DFP Arithmetic Operations +//! +//! Implements deterministic arithmetic per RFC-0104. +//! +//! # Bug fixes applied (see review doc for full analysis) +//! +//! ## ADD (Bug A1 — ADD sign after align_mantissa for large exponent diff) +//! `align_mantissa(dfp, diff >= 128)` previously returned `Dfp::zero()` (class = Zero, +//! sign = false). This caused the subtraction branch to pick up the wrong sign when the +//! smaller operand was negative and its entire mantissa vanished due to the large shift. +//! Fix: return a zero-value Dfp that keeps the *original* sign and class = Normal so +//! the existing sign logic sees the correct sign before deciding on result_sign. +//! +//! ## ADD (Bug A2 — same-sign addition carry discarded) +//! `a.mantissa.overflowing_add(b.mantissa)` silently dropped the carry flag. +//! Fix: keep the carry and inject it into round_to_113 by using a u128 + u128 addition +//! whose result is held in a wider intermediate before the truncating round. +//! Both mantissas are at most 113 bits (odd, canonical), so their sum is at most +//! 114 bits. We widen to i128 before calling round_to_113 so the carry bit (bit 113) +//! becomes the round-bit input, which is exactly what round_to_113 already handles. +//! +//! ## MUL (Bug M1 — exponent shift sign inverted in the product_msb > 112 branch) +//! Code had `(rm, ea - shift_right as i32)` — the shift_right was subtracted. +//! RFC requires result_exponent += exp_adj + shift_amount. +//! Shifting the product RIGHT by shift_right *increases* the exponent by shift_right +//! (each right-shift is a ÷2, so the implicit 2^x factor rises by 1 per shift). +//! Fix: `result_exponent = base + ea + shift_right as i32`. +//! +//! ## MUL (Bug M2 — product_msb <= 112 branch passed `lo_bits as i128` to round_to_113) +//! When product_msb <= 112, hi == 0 and lo holds the full product. +//! The mask `(1u128 << 114) - 1` kept 114 bits of lo but round_to_113 expects +//! the value already positioned with bit 112 as the LSB to keep. When the product +//! genuinely fits in <= 112 bits there is nothing to round; the value is passed +//! straight through and exp_adj=0, which is correct. However the mask was +//! needlessly restricting guard bits used for stickiness. The simpler fix is to +//! just pass lo directly (only lo, since hi=0) to round_to_113 and let it handle +//! the correct position. But the real fix is to unify both branches: always use +//! the full U256 shift-and-align path, eliminating the special-case branch entirely. +//! +//! ## DIV (Bug D1 — quotient accumulator is u128, overflows for a_m > b_m) +//! The loop accumulates ONE bit per iteration. Starting with dividend_hi=a_m, after +//! N iters the quotient equals the first N bits of the binary expansion of a_m/b_m +//! anchored at bit 2^(-1) (i.e., the fractional expansion with the integer part +//! possibly missing). For a_m >> b_m (e.g. 7/1), nearly all 128 bits are 1, giving +//! a wildly wrong result. Fix: pre-scale b_m left until b_m > a_m (tracking the +//! scale factor), guaranteeing a_m < b_m so the quotient is in (0,1) and all 128 +//! bits are below the radix point. The scale factor is folded back into the exponent. +//! +//! ## DIV (Bug D2 — exponent formula uses magic constant -240 based on u128 MSB) +//! The original formula `final_exponent = result_exponent + (quotient_msb as i32) - 240` +//! was derived assuming a 256-bit MSB position, but with a u128 quotient the MSB is +//! at most 127, giving a large negative exponent for almost all inputs. +//! Fix: with the pre-scaled approach, exponent = (a_e - b_e) + exp_adj + shift + scale - 128. +//! +//! ## SQRT (Bug S1 — bit loop runs 0..128 instead of 0..226) +//! RFC requires 226 iterations (bits 225 down to 0) for 113-bit precision. +//! With only 128 bits the result has at most 128 significant bits and the +//! mantissa extraction formula is also wrong. +//! +//! ## SQRT (Bug S2 — shl_256((0, adjusted_mantissa), 226) overflows hi word) +//! A 113-bit mantissa shifted left 226 needs 339 bits. The (hi,lo) representation +//! holds only 256 bits; the hi word can hold at most 128 bits of the shifted value, +//! but `adjusted_mantissa << (226-128) = adjusted_mantissa << 98` yields a 211-bit +//! number, overflowing hi. Fix: use a true 512-bit (4×u128) representation for +//! the scaled input and for the candidate² comparison. +//! +//! ## SQRT (Bug S3 — mantissa extraction wrong bit positions) +//! Code used `(sqrt.0 >> 15) | (sqrt.1 >> 79)` — mixed shifts with wrong amounts. +//! Correct formula for extracting bits [225:113] from a (hi,lo) 256-bit integer: +//! `(hi << 15) | (lo >> 113)`. +//! +//! ## SQRT (Bug S4 — exponent has spurious +1) +//! `result_exponent = exponent_quotient + 1` — the +1 is from a stale wrong algorithm. +//!

This report provides a comprehensive examination of the current state of ZKP technology as of 2025-2026, analyzing the fundamental cryptographic concepts, major protocol implementations, and the growing ecosystem of Rust-based development tools. The research reveals that the ZK proof market has expanded to over $28 billion in total value locked across major rollup implementations, with projected growth to $7.59 billion by 2033. Key findings indicate that zk-SNARKs continue to dominate due to their compact proof sizes and efficient verification, while zk-STARKs are gaining traction for their quantum resistance and lack of trusted setup requirements. The blockchain industry has seen significant deployment of these technologies through projects like zkSync Era, StarkNet, Polygon zkEVM, and Scroll, each taking distinct technical approaches to achieving Ethereum compatibility. The Rust ecosystem has matured considerably with libraries like arkworks, Bellman, and Halo2 providing robust foundations for ZKP development. + +## 1. Introduction + +The advent of blockchain technology has revolutionized digital transactions by enabling trustless peer-to-peer exchanges without requiring intermediaries. However, public blockchains face fundamental challenges regarding privacy and scalability. Zero knowledge proofs offer an elegant cryptographic solution to both problems by allowing one party to prove to another that a statement is true without revealing any information beyond the validity of the statement itself. This capability has profound implications for blockchain networks, where maintaining transaction privacy while achieving throughput comparable to traditional financial systems remains an active area of research and development. + +The concept of zero knowledge proofs was first formally introduced in a landmark 1985 MIT paper by Shafi Goldwasser and Silvio Micali titled "The Knowledge Complexity of Interactive Proof-Systems" [32]. Since then, the technology has evolved from theoretical cryptographic constructs to practical systems powering real-world blockchain deployments. The period from 2023 to 2026 has been particularly transformative, with major blockchain projects deploying production-ready ZK rollups that collectively process millions of transactions daily while maintaining the security guarantees of the underlying Layer 1 networks. + +This report examines three critical dimensions of the ZKP landscape. First, it explores the fundamental properties that define zero knowledge proofs and the technical characteristics of major protocols including zk-SNARKs, zk-STARKs, Bulletproofs, and PLONK. Second, it analyzes how these cryptographic primitives have been implemented in major blockchain projects such as zkSync Era, StarkNet, Polygon zkEVM, and Scroll, comparing their technical approaches and trade-offs. Third, it surveys the Rust implementation ecosystem, examining libraries like arkworks, Bellman, and Halo2 that enable developers to build ZKP-powered applications. The analysis draws upon current documentation, technical specifications, and industry reports to provide a comprehensive view of this rapidly evolving field. + +## 2. Fundamentals and Current State of ZKP Technology + +### 2.1 Core Concepts and Properties + +Zero knowledge proofs are cryptographic protocols that enable one party, known as the prover, to convince another party, the verifier, that a specific statement is true without revealing any information beyond the fact that the statement is indeed true [38]. This seemingly paradoxical capability relies on sophisticated mathematical constructions that allow verification through probabilistic methods rather than direct disclosure of the underlying data. The power of ZKPs lies in their ability to preserve privacy while maintaining verifiability, a combination that has proven invaluable for blockchain applications where transparency and confidentiality must coexist. + +The formal definition of zero knowledge proofs encompasses three fundamental properties that every valid ZKP system must satisfy [25]. Completeness ensures that if a statement is actually true, an honest prover can successfully convince an honest verifier of this truth. This property guarantees that legitimate proofs are always accepted by the system. Soundness, the second critical property, ensures that if a statement is false, no cheating prover can convince an honest verifier that it is true except with negligible probability. This prevents fraudsters from generating false proofs. The third property, zero-knowledge, is perhaps the most distinctive: it guarantees that the verifier learns nothing from the proof beyond the fact that the statement is true. Specifically, the verifier gains no information about the secret data that would enable them to prove the statement to others independently [32]. + +Zero knowledge proofs can be broadly categorized into interactive and non-interactive variants [32]. Interactive ZKPs require multiple rounds of communication between the prover and verifier, with the verifier issuing challenges that the prover must respond to correctly. While conceptually important and useful for certain applications, interactive proofs are impractical for blockchain contexts where a single proof must be verifiable by many parties without direct communication. Non-interactive ZKPs resolve this limitation by allowing the prover to generate a single proof that anyone can verify independently. This property is essential for blockchain applications where transaction proofs must be validated by the network without requiring ongoing dialogue between the original prover and each verifier. + +### 2.2 Current State and Market Overview + +The ZKP technology landscape has experienced remarkable growth and maturation between 2024 and 2026, driven primarily by the adoption of zero-knowledge rollups for Ethereum scaling [37]. The total value locked in ZK rollup solutions has exceeded $28 billion, representing a substantial portion of Ethereum's Layer 2 ecosystem. This market growth reflects the increasing recognition that ZKPs provide the most promising path toward achieving both privacy and scalability in public blockchain networks. Major financial institutions and technology companies have invested billions of dollars in ZKP research and development, accelerating the pace of innovation and bringing new products to market. + +The zero knowledge proof market itself is projected to grow from $1.28 billion in 2024 to $7.59 billion by 2033, representing a compound annual growth rate of 22.1% [11]. This growth is fueled by several factors including the maturation of ZK rollup technology, increasing demand for privacy-preserving financial services, and the emergence of new use cases beyond simple transaction privacy. The technology is finding applications in identity verification, supply chain transparency, decentralized finance, and even machine learning verification. Additionally, the growing concern over quantum computing threats has elevated interest in post-quantum ZKP schemes like zk-STARKs that rely on cryptographic assumptions believed to be resistant to quantum attacks. + +Ethereum has become the primary battleground for ZKP deployment, with over 60% of Layer 2 transactions now processed by ZK-based solutions [11]. This dominance reflects both the technical advantages of ZK rollups over alternative scaling approaches like optimistic rollups and the substantial investment by major teams in developing and deploying these systems. The competition among zkSync Era, StarkNet, Polygon zkEVM, Scroll, and other implementations has driven rapid improvements in performance, developer experience, and ecosystem tooling. Each project has made different trade-offs regarding compatibility, performance, and decentralization, creating a diverse landscape of options for developers building on Ethereum's Layer 2 infrastructure. + +## 3. Major Types of Zero Knowledge Proofs + +### 3.1 zk-SNARKs + +Zero-knowledge Succinct Non-interactive Arguments of Knowledge (zk-SNARKs) represent the most widely deployed ZKP technology in blockchain applications today [32]. The term succinctly captures the key properties: zero-knowledge ensures privacy, succinctness refers to the compact proof size, non-interactive means single-round verification, and arguments of knowledge indicates computational soundness rather than perfect soundness. SNARKs have been deployed in production systems including Zcash for privacy-preserving transactions and numerous Ethereum Layer 2 scaling solutions. + +The technical foundation of zk-SNARKs relies on elliptic curve cryptography, specifically bilinear pairings constructed from elliptic curves [25]. This mathematical structure enables the creation of compact proofs that can be verified quickly regardless of the complexity of the underlying computation. A typical zk-SNARK proof is approximately 200 bytes in size, making it practical to include on-chain and transmit over networks with limited bandwidth [25]. The verification complexity is constant O(1), meaning verification time remains the same regardless of how complex the proven statement is. This efficiency makes SNARKs particularly suitable for blockchain applications where on-chain verification costs must be minimized. + +However, zk-SNARKs come with significant trade-offs that have influenced their adoption patterns. The most notable limitation is the requirement for a trusted setup ceremony, a process in which initial cryptographic parameters are generated in a way that requires at least one participant to act honestly [23]. If all participants collude or the setup is compromised, the security of the entire system can be undermined. While trusted setup ceremonies can involve hundreds of participants to increase confidence, the requirement nonetheless introduces an initial trust assumption that some projects find unacceptable. Additionally, zk-SNARKs rely on elliptic curve cryptography, which is not believed to be secure against quantum computers, making them potentially vulnerable in a post-quantum future [25]. + +Several notable implementations have advanced the state of zk-SNARKs since their initial deployment. Groth16, developed by Jens Groth, offers extremely compact proofs and fast verification but requires a circuit-specific trusted setup. Marlin and PLONK introduced universal trusted setups where a single ceremony supports any circuit up to a certain size. These advances have reduced the operational burden of maintaining SNARK-based systems while maintaining the core benefits of small proof sizes and efficient verification. + +### 3.2 zk-STARKs + +Zero-knowledge Scalable Transparent Arguments of Knowledge (zk-STARKs) were developed to address some of the fundamental limitations of zk-SNARKs, particularly the trusted setup requirement and vulnerability to quantum attacks [32]. STARKs achieve transparency through the use of publicly verifiable randomness and collision-resistant hash functions rather than secret cryptographic parameters. This eliminates the need for any trusted setup ceremony and provides security based on assumptions that are widely believed to hold even against quantum computers. + +The scalability properties of zk-STARKs distinguish them from other ZKP protocols, particularly for large-scale computations [25]. The prover complexity scales as O(N × poly-log(N)), where N represents the size of the computation, making STARKs highly efficient for complex statements. This scalability has made STARKs the preferred choice for applications requiring proofs of very large computations, such as entire blockchain state transitions. The transparency of STARKs also means that the security of the system does not depend on any secret information being properly destroyed after an initial setup phase, reducing the risk of catastrophic failure due to setup compromise. + +The trade-offs for these advantages include larger proof sizes and higher computational requirements during proof generation [25]. A single STARK proof is approximately 45 kilobytes, roughly 225 times larger than a comparable SNARK proof. These larger proofs translate to higher gas costs when verified on Ethereum, approximately 2.5 million gas compared to roughly 600,000 gas for SNARK verification. Additionally, the prover must perform more computation to generate STARK proofs compared to SNARKs, though the development of specialized hardware and optimized implementations has narrowed this gap significantly. StarkNet, built by StarkWare, has become the primary production deployment of STARK technology, demonstrating that the trade-offs are acceptable for many real-world applications. + +### 3.3 Bulletproofs + +Bulletproofs represent a different approach to zero knowledge proofs, optimized specifically for range proofs and confidential transactions [25]. Originally developed by Bootle et al. and further improved by Bünz et al., Bulletproofs enable proof that a secret value lies within a specified range without revealing the value itself. This capability is particularly valuable for cryptocurrency systems that need to verify transaction amounts are positive without publicly disclosing the exact amounts. Monero, a privacy-focused cryptocurrency, adopted Bulletproofs to reduce the data size and costs of confidential transactions by up to 80%. + +The technical design of Bulletproofs avoids trusted setup requirements entirely by relying on the discrete logarithm assumption and the Fiat-Shamir heuristic for non-interactivity [25]. This makes Bulletproofs easier to deploy in practice since there is no ceremony to coordinate and no risk of compromised setup parameters. The proof sizes are relatively compact at approximately 1.5 kilobytes, significantly smaller than STARKs but larger than SNARKs. This positions Bulletproofs as a middle-ground option in the proof size trade-off spectrum. + +The primary limitation of Bulletproofs is their verification complexity, which scales linearly O(N) with the size of the statement being proven [25]. This makes them less suitable for complex computations compared to SNARKs or STARKs, but their optimization for range proofs means they excel at their specific use case. For applications requiring only simple range proofs, such as verifying that a transaction amount is positive without revealing the exact amount, Bulletproofs offer an excellent balance of properties. The lack of trusted setup, compact proof sizes for their intended use case, and strong security foundations have ensured their continued relevance in privacy-focused blockchain systems. + +### 3.4 PLONK and Modern SNARKs + +PLONK, standing for Permutations over Lagrange-bases for Oecumenical Noninteractive arguments of Knowledge, represents a significant advancement in general-purpose ZK-SNARK technology [71]. Introduced by Ariel Gabizon, Zac Williamson, and Oana Ciobotaru, PLONK builds upon earlier protocols like SONIC and Marlin while introducing key improvements that have made it one of the most widely adopted ZK proof systems in recent years. The protocol has become particularly popular in the blockchain scaling space, with implementations in Polygon zkEVM and numerous other projects. + +The architectural innovation of PLONK lies in its universal and updateable trusted setup [72]. Unlike circuit-specific setups that must be performed separately for each application, a single PLONK setup ceremony can support any program up to a maximum size defined during the initial setup. This dramatically reduces the operational overhead of deploying multiple ZK applications while maintaining the security benefits of a multi-party ceremony. The setup is also updateable, meaning participants can contribute fresh randomness to extend the life of the setup or repair potential compromise, providing ongoing security guarantees that single-shot setups cannot match [71]. + +Performance characteristics of PLONK demonstrate substantial improvements over earlier SNARK constructions [71]. For circuits exceeding one million gates, PLONK can generate proofs in under 23 seconds using consumer-grade hardware. The protocol requires only five polynomial commitments and two opening proofs, significantly reducing the computational burden on the prover compared to earlier protocols. The standardized polynomial commitment scheme, typically Kate commitments based on trusted setups and elliptic curve pairings, provides flexibility to swap in alternative commitment schemes like FRI or DARK for different security trade-offs [72]. This modularity has enabled PLONK to serve as a foundation for further innovations in the ZKP space. + +## 4. ZK Solutions in Major Blockchain Projects + +### 4.1 zkSync Era by Matter Labs + +zkSync Era, developed by Matter Labs, stands as one of the leading zero-knowledge rollup implementations on Ethereum, having processed over 27 million transactions monthly as of 2025 [11]. The project launched in March 2023 and has since accumulated significant TVL while maintaining strong security guarantees through its novel proof system. zkSync Era represents a comprehensive approach to Ethereum scaling that goes beyond simple transaction compression to include native account abstraction, a custom zkEVM, and an ambitious roadmap for decentralized proving. + +The technical architecture of zkSync Era centers on the Boojum proof system, a recursive STARK-based construction that achieves 100-bit security target while maintaining practical performance [67]. Boojum uses the Redshift protocol, which combines Plonk IOP with List Polynomial Commitments based on FRI for the core proving system. This transparent scheme avoids trusted setup requirements for the main proof generation while wrapping the final proof using Plonk with KZG commitments over the BN254 curve for efficient Ethereum verification. The system utilizes 15 different circuit types organized in a multi-layer recursive architecture including node circuits, scheduler circuits, compressor circuits, and wrapper circuits that progressively aggregate and compress proofs [67]. + +The EraVM instruction set architecture provides compatibility with Ethereum's EVM while introducing optimizations for zero-knowledge proof generation [67]. Unlike EVM's stack-based architecture, EraVM uses 16 registers that enable more efficient compilation and proof generation. The LLVM compiler infrastructure allows zkSync Era to support multiple programming languages including Solidity, Vyper, and Yul, transforming them into zkVM bytecode that can be proven efficiently. This approach achieves a balance between EVM compatibility and ZK-optimized performance, though developers may need to make some adjustments to their existing tooling. + +Native account abstraction represents a distinctive feature of zkSync Era's design philosophy [11]. Unlike Ethereum mainnet where accounts and contracts are fundamentally different, zkSync Era treats all accounts as smart contracts at the protocol level. This enables powerful capabilities like gas fee sponsorship where third parties can pay transaction fees on behalf of users, batched transactions that combine multiple operations, and sophisticated permission systems that can implement complex access control logic. These features have attracted significant DeFi activity, with major protocols like SyncSwap and Mute.io reporting transaction cost reductions exceeding 90% compared to Ethereum mainnet, dropping fees from $2-3 to under $0.05 per transaction. + +Matter Labs has continued advancing the technology through the Boojum 2.0 initiative, currently in development as of early 2025 [61]. This next-generation system utilizes a RISC-V-based proving architecture designed to deliver substantial improvements in both cost and performance. The open-sourcing of CPU and GPU provers under the names era-boojum and era-shivini has enabled broader community participation in proof generation and optimization [68]. The zkStack framework extends the Boojum technology to support multiple interconnected ZK-powered chains, enabling horizontal scaling and interoperability across the ecosystem. + +### 4.2 StarkNet by StarkWare + +StarkNet, developed by StarkWare Industries, represents the production deployment of zk-STARK technology for general-purpose blockchain scaling [52]. Operating as a Layer 2 validity rollup on Ethereum, StarkNet processes transactions by executing them on the StarkNet sequencer and generating STARK proofs that attest to the correctness of the state transition. These proofs are then verified on Ethereum, inheriting Ethereum's security while achieving throughput far beyond what the base chain can support. Since its launch, the StarkNet ecosystem has powered over $1.5 trillion in transaction volume through the StarkEx scaling engine and executed more than one billion individual transactions. + +The choice of zk-STARKs as the underlying proof system gives StarkNet unique properties among major rollup implementations [51]. The absence of a trusted setup requirement means StarkNet's security does not depend on any secret parameters that could potentially compromise the entire system if mishandled. This transparency provides stronger security assurances than SNARK-based alternatives. Furthermore, STARKs rely on collision-resistant hash functions rather than elliptic curve cryptography, making StarkNet's proof system quantum-resistant and future-proof against advances in quantum computing that could break current encryption standards. + +Cairo, the programming language purpose-built for StarkNet, represents a distinctive aspect of the StarkWare ecosystem [53]. Unlike approaches that attempt to maximize compatibility with existing Ethereum tooling by implementing EVM-compatible virtual machines, StarkNet chose to design a new language optimized for provable computing. Cairo compiles to an ad-hoc assembly specifically engineered for efficient proof generation, enabling significant performance improvements over EVM-based alternatives. The language draws inspiration from Rust, emphasizing memory safety and efficient code generation. Cairo 1.0, released in 2024, brought substantial improvements in usability, safety, and developer experience while maintaining the performance advantages of the original design. + +The year 2025 marked a pivotal period for StarkNet with major technical upgrades transforming its capabilities [51]. The v0.13.5 release in March 2025 introduced stateful compression, making StarkNet the first rollup to optimize blob usage for reduced fees. The v0.14.0 "Grinta" upgrade in September 2025 delivered the first decentralized sequencer architecture in production, with three sequencers running in rotation and pre-confirmations reducing latency from 2 seconds to 500 milliseconds. Block times dropped from 30 seconds to just 4 seconds, while TPS capacity doubled to over 1,000 with peaks reaching 2,630 UOPS. The November 2025 integration of the S-two prover delivered a 100x efficiency improvement over the previous Stone prover, with client-side proving now possible on consumer hardware. + +StarkNet has made substantial progress on decentralization throughout 2025 [51]. The staking mechanism saw STRK staked increase eleven-fold from 110 million to over 1.1 billion, with 23% of circulating supply now staked. The introduction of BTC staking in October 2025 created the first rollup to tether security to Bitcoin, with a dual-token consensus model using 75% STRK and 25% BTC. Over 1,700 BTC valued at approximately $160 million has been staked in just three months. The roadmap for 2026 includes full prover decentralization, sub-second block times, and expansion of the BTCFi ecosystem with a trust-minimized Bitcoin bridge through the Alpen partnership. + +### 4.3 Polygon zkEVM + +Polygon zkEVM represents Polygon Labs' entry into the zero-knowledge rollup space, backed by over $1 billion in committed investment to ZKP adoption [11]. Launched in March 2023, Polygon zkEVM implements a Type 3 zkEVM in Vitalik Buterin's classification system, achieving bytecode-level EVM compatibility that allows developers to deploy existing Solidity contracts with minimal modifications. This approach prioritizes ecosystem compatibility over maximum optimization, enabling a faster transition for the large existing base of Ethereum developers and smart contracts. + +The technical implementation of Polygon zkEVM uses zkSNARK proofs generated from circuits that precisely mirror EVM execution semantics [11]. This design decision required substantial engineering investment to correctly capture all EVM opcodes and edge cases in zero-knowledge circuits, but results in near-perfect compatibility with the Ethereum developer ecosystem. Developers can deploy their existing smart contracts to Polygon zkEVM without rewriting or extensive modification, dramatically reducing the migration burden. The Polygon CDK (Chain Development Kit) extends this capability by allowing projects to launch their own custom ZK-powered chains using Polygon infrastructure while maintaining compatibility with the broader Polygon ecosystem. + +The AggLayer architecture represents Polygon's approach to interoperability across its growing network of ZK-powered chains [11]. Rather than treating each chain as an isolated execution environment, AggLayer stitches together liquidity and finality across Polygon's rollup ecosystem using a superchain model. This enables seamless asset transfers and message passing between different Polygon chains while maintaining the security benefits of zero-knowledge proofs. The architectural vision encompasses multiple specialized chains serving different use cases while presenting a unified interface to users and developers. + +Gaming applications have found Polygon zkEVM particularly attractive, with several Web3 gaming studios migrating to take advantage of the combination of low costs and EVM compatibility [11]. Transaction costs dropped from $2-3 on Ethereum mainnet to under $0.05 while maintaining full compatibility with existing Ethereum development tools and workflows. This has enabled game developers to build more sophisticated on-chain games that would be economically impractical on Layer 1 Ethereum, driving adoption in the gaming vertical. The project continues to face challenges including higher fees compared to some competitors and ongoing questions about the role of the MATIC token in network operations. + +### 4.4 Scroll and Other zkEVM Implementations + +Scroll has emerged as the third-largest Ethereum Layer 2 by TVL at $748 million as of mid-2025, while achieving the largest market share among zkEVM implementations [11]. The Scroll team's approach emphasizes maximum EVM equivalence, implementing a Type 2 zkEVM that achieves bytecode-equivalence with Ethereum rather than merely opcode compatibility. Every EVM opcode is supported directly, meaning the full Ethereum tool ecosystem works seamlessly without modification. The October 2024 launch of the SCR token, while controversial, validated the project's commitment to decentralization and community ownership. + +The decentralized proof generation network represents Scroll's distinctive technical approach to scaling proof production [11]. Rather than relying on a single centralized prover, Scroll distributes proof generation across a network of validators. This architectural decision improves both the liveness and censorship resistance of the system while potentially reducing costs through competition among provers. The design draws on Halo2 as the underlying proof system, with Scroll contributing improvements and optimizations back to the open-source Halo2 ecosystem. + +The practical benefits of Scroll's EVM equivalence were demonstrated when Aave deployed on Scroll with zero contract modifications [11]. The deployment took hours rather than the weeks that might be required on less compatible systems, and transaction costs reduced by over 95%. This near-perfect compatibility has attracted projects that prioritize migration speed and ecosystem tool compatibility over maximum performance optimization. The trade-off is that Scroll's performance characteristics are bound by EVM semantics rather than the more aggressive optimizations possible with custom VM designs. + +Linea, developed by ConsenSys, represents another significant zkEVM implementation with approximately $2 billion in TVL [11]. As ConsenSys's ZK rollup offering, Linea benefits from deep integration with the broader ConsenSys product suite including MetaMask and Infura. This integration provides Linea with strong tooling support and developer relationships. The implementation uses zkSNARK proofs and achieves Type 2 EVM equivalence similar to Scroll. Aztec Network takes a different approach as a privacy-first hybrid ZK rollup using dual-layer ZK proofs that provide both encryption and compression, enabling private transactions while maintaining compatibility with Ethereum's execution environment. + +## 5. Rust Implementations of ZKP + +### 5.1 The Arkworks Ecosystem + +The arkworks-rs ecosystem has established itself as the preeminent collection of Rust libraries for designing and working with zero knowledge succinct non-interactive arguments [2]. This comprehensive framework provides the foundational infrastructure for building ZKP applications in Rust, with a modular architecture that separates concerns between polynomial commitments, proof systems, and constraint systems. The ecosystem's design philosophy emphasizes composability and cryptographic flexibility, enabling developers to mix and match components to achieve specific performance and security requirements. + +The core of the arkworks ecosystem centers on two primary libraries. The ark-snark crate provides generic traits for zkSNARKs, encapsulating the functionality required to produce and verify proofs across different proof system implementations [2]. The ark-relations crate defines generic traits for NP relations, including the widely-used R1CS (Rank-1 Constraint System) format that serves as an intermediate representation for computations to be proven. This separation allows developers to express their computations in a high-level constraint language while remaining agnostic to the specific proof system used for verification. + +Several major proof system implementations exist within the arkworks ecosystem, including Groth16, GM17, and Marlin [2]. Each implementation satisfies the generic SNARK trait, enabling applications to switch between proof systems without modifying application logic. The Groth16 implementation provides highly optimized proofs for circuits with known size at setup time, while Marlin offers a universal setup that can support multiple circuits with a single ceremony. The modular design also extends to polynomial commitments, with implementations supporting different algebraic constructions to achieve various trade-offs between proof size, verification time, and security assumptions. + +The arkworks project carries important disclaimers regarding production use [2]. As an academic proof-of-concept implementation, the code has not undergone the extensive security auditing that production cryptographic systems require. The documentation explicitly warns that the implementation is not ready for production use without careful review and hardening. Despite this caution, arkworks has become the foundation for numerous research projects and production systems, with contributions from organizations including the Ethereum Foundation, Interchain Foundation, and various blockchain projects. The ecosystem maintains over 890 stars on GitHub and continues to receive active development and maintenance. + +### 5.2 Bellman and zk-SNARK Implementations + +Bellman stands as a foundational Rust library for building zk-SNARKs, originally developed by the Zcash team and now maintained as an open-source project [6]. The library provides efficient implementations of the cryptographic primitives required for SNARK construction, with a focus on the BN254 curve that enables compatibility with Ethereum's cryptographic infrastructure. Bellman's design emphasizes correctness and performance, implementing optimized arithmetic operations that leverage Rust's ownership system to prevent common programming errors while maintaining competitive performance. + +The technical implementation in Bellman follows the Groth16 proof system, one of the most efficient SNARK constructions for circuits with circuit-specific trusted setups [8]. The library handles the complex polynomial arithmetic, commitment schemes, and pairing-based verification that constitute modern SNARKs. Developers using Bellman define their computations as arithmetic circuits, which are then compiled into the format required for proof generation. The resulting proofs are compact enough to be published on-chain and verified with minimal gas costs, making Bellman suitable for blockchain applications. + +Bellman has proven its production readiness through deployment in Zcash, the privacy-focused cryptocurrency that pioneered practical zero-knowledge proofs at scale [6]. The library has protected billions of dollars in value while maintaining the privacy guarantees that Zcash users expect. This real-world deployment has driven continuous improvements in both security and performance, with the library undergoing extensive testing and review. The Zcash community's continued investment in Bellman ensures the library remains current with the latest cryptographic research and performance optimizations. + +### 5.3 Halo2 and Scroll's Implementation + +Halo2, developed by the Electric Coin Company (Zcash), represents the most widely adopted ZK proof system in production blockchain applications today [46]. The library implements a recursive SNARK construction that eliminates the need for circuit-specific trusted setups through the use of polynomial commitments with opening proofs. This architectural choice provides substantial flexibility, as a single setup can support circuits of varying sizes up to a defined maximum bound. Halo2's design emphasizes practical usability while maintaining the cryptographic rigor expected for financial applications. + +The halo2 library requires Rust version 1.60 or higher, with support for both single-threaded and multi-threaded operation [46]. Parallel computation is enabled through the rayon library, with the RAYON_NUM_THREADS environment variable controlling the number of worker threads. Developers can disable the multicore feature if single-threaded operation is preferred, though this significantly impacts performance for proof generation. The library includes both halo2_proofs for the core proving system and halo2_gadgets for reusable circuit components that simplify common cryptographic operations. + +Scroll's zkEVM implementation relies heavily on Halo2, with the team contributing substantial improvements and optimizations back to the ecosystem [44]. The Scroll team has open-sourced their Halo2-based circuit development tools through the scroll-tech/zk-mooc-halo2 repository, providing educational resources for developers learning to build ZK circuits. This commitment to open-source development has helped grow the Halo2 developer community while improving the quality and documentation of available tooling. + +The Halo2 ecosystem extends beyond Scroll and Zcash to numerous other blockchain projects [45]. Polygon zkEVM's implementation utilizes a Halo2 fork with KZG support from both the Ethereum Foundation and Scroll. The Axiom project has developed halo2-lib, a monorepo of Halo2 crates providing basic primitives for writing zero-knowledge proof circuits. This broad adoption has created a rich ecosystem of reusable components, tutorials, and tooling that lowers the barrier to entry for new developers building ZKP applications. + +### 5.4 Cairo and StarkNet Development + +While Cairo is not implemented in Rust, it represents an important language in the ZKP development landscape that warrants coverage in this report. Cairo is a modern programming language developed by StarkWare, specifically designed for writing provable programs that can be verified using STARK proofs [53]. The language draws inspiration from Rust, adopting similar syntax and emphasizing memory safety and efficient code generation. Cairo compiles to a custom assembly language optimized for proof generation, enabling significantly better performance than general-purpose languages compiled to EVM bytecode. + +The Cairo ecosystem provides comprehensive tooling for developers building on StarkNet [53]. The Cairo Book offers extensive documentation covering everything from basic programming concepts to advanced optimization techniques. The Cairo Playground enables developers to experiment with code in a browser-based environment without local setup. StarkWare maintains active development with regular releases, including Cairo v2.12.0 as the most recent version. The language continues to evolve with new features that improve both developer experience and generated proof efficiency. + +The S-two prover, integrated into StarkNet in late 2025, represents the latest advancement in Cairo's proving infrastructure [51]. This prover achieves 100x efficiency improvements over the previous Stone prover, enabling client-side proving on consumer hardware. The development of the Cairo Coder tool in 2025 further simplifies onboarding for developers familiar with other programming languages. The combination of an optimized language, high-performance provers, and comprehensive tooling has established Cairo as a leading choice for developers building ZK-powered applications that prioritize performance and scalability. + +## 6. Comparative Analysis and Trade-offs + +### 6.1 Technical Trade-offs Between ZKP Types + +The choice between different zero knowledge proof systems involves fundamental trade-offs that blockchain projects must carefully evaluate based on their specific requirements. zk-SNARKs offer the smallest proof sizes at approximately 200 bytes and constant-time verification complexity O(1), making them ideal for applications where on-chain verification costs are paramount [25]. However, these benefits come at the cost of a trusted setup requirement and vulnerability to quantum attacks. The trusted setup creates a single point of failure that must be carefully managed through multi-party ceremonies, while the elliptic curve cryptography underlying SNARKs could become insecure if sufficiently powerful quantum computers are developed. + +zk-STARKs provide an attractive alternative for applications where security transparency and future-proofing take precedence over proof size [25]. The absence of a trusted setup eliminates an entire class of potential security vulnerabilities, while quantum resistance ensures long-term security even in the face of dramatic advances in computing. The trade-off manifests in larger proof sizes of approximately 45 kilobytes and higher on-chain verification costs of roughly 2.5 million gas compared to 600,000 gas for SNARKs. For applications prioritizing security over efficiency, particularly those expected to operate over decades, STARKs offer compelling advantages. + +Bulletproofs occupy a specialized niche optimized for range proofs and confidential transactions [25]. Their lack of trusted setup and compact proof sizes for their intended use cases make them the preferred choice for cryptocurrency systems requiring transaction amount privacy. However, the linear verification complexity O(N) limits their applicability to more complex computations. Projects like Monero have successfully deployed Bulletproofs for confidential transactions, demonstrating their practical utility for specific use cases. + +PLONK and modern SNARK constructions provide a middle ground by offering universal trusted setups that reduce operational complexity while maintaining the compact proofs and efficient verification of traditional SNARKs [71]. The ability to reuse a single setup across multiple applications democratizes access to ZK technology, as projects no longer need to coordinate their own trusted setup ceremonies. This has accelerated the deployment of ZK applications across the blockchain ecosystem. + +### 6.2 Blockchain Project Comparison + +The major ZK rollup implementations have made distinct technical choices that result in different characteristics and trade-offs for users and developers. zkSync Era prioritizes maximum scalability and native account abstraction, using a custom VM design that achieves significant performance improvements over EVM-compatible alternatives [11]. The trade-off is that developers must adapt to the zkSync environment, with some tool modifications required. The Boojum proof system provides strong security through recursive STARK construction, while the active development of Boojum 2.0 promises continued performance improvements. + +StarkNet's choice of zk-STARKs provides unique security properties including quantum resistance and no trusted setup requirement [51]. The trade-off manifests in the need to learn Cairo rather than using familiar Solidity, and a smaller ecosystem of tools compared to EVM solutions. However, the 2025 technical improvements have substantially closed the performance gap, with TPS capacity exceeding 1,000 and transaction costs below $0.001. The decentralization progress through staking and BTC integration positions StarkNet as a leading option for projects prioritizing security and decentralization. + +Polygon zkEVM maximizes EVM compatibility at the cost of some performance optimization [11]. This approach minimizes friction for developers migrating from Ethereum, enabling existing smart contracts to deploy with minimal modification. The substantial investment of over $1 billion demonstrates long-term commitment to the ZK space. The AggLayer architecture provides interoperability benefits across the Polygon ecosystem, though users face higher fees compared to more optimized alternatives. + +Scroll's Type 2 zkEVM implementation represents the closest approach to native Ethereum [11]. The bytecode-equivalence ensures that every EVM opcode works identically to the base chain, eliminating surprising differences that can cause bugs during migration. This has attracted major DeFi protocols like Aave that prioritize migration speed and ecosystem compatibility. The decentralized proof generation network provides architectural advantages for censorship resistance. + +### 6.3 Rust Ecosystem Comparison + +The Rust ZKP libraries serve different use cases and offer distinct trade-offs for developers. Arkworks provides the most comprehensive framework with support for multiple proof systems and flexible component composition [2]. The modular architecture enables developers to experiment with different constructions and optimize for specific requirements. However, the academic nature of the implementation means it requires careful security review before production deployment. The extensive documentation and active community support make it an excellent choice for research projects and applications with extended development timelines. + +Bellman offers a production-proven implementation with the strongest track record of securing significant financial value [6]. The Zcash deployment has subjected the library to intense scrutiny and real-world testing. Developers seeking maximum assurance of correctness may prefer Bellman, accepting the trade-off of working with a more opinionated library focused on a specific proof system. The tight integration with BN254 curve operations makes it particularly suitable for Ethereum-compatible applications. + +Halo2 has emerged as the dominant choice for new blockchain projects due to its flexibility and the substantial ecosystem built around it [46]. The support for universal setup reduces operational complexity, while the extensive tooling and documentation lower the barrier to entry. Projects like Scroll have demonstrated Halo2's capability to handle production workloads with billions of dollars in value. The ongoing development and community support ensure continued improvement and long-term viability. + +## 7. Conclusion + +Zero knowledge proofs have matured from theoretical cryptographic constructs into practical technologies powering real-world blockchain applications. The period from 2024 to 2026 has witnessed remarkable growth in ZKP deployment, with over $28 billion in total value locked across major ZK rollups and the broader proof market projected to reach $7.59 billion by 2033. This growth reflects both the technical maturity of ZK systems and the increasing recognition that privacy and scalability are fundamental requirements for blockchain adoption in financial applications. + +The diverse landscape of ZKP protocols provides solutions tailored to different requirements. zk-SNARKs continue to dominate applications where proof size and verification efficiency are paramount, while zk-STARKs have gained significant traction for their security properties including quantum resistance and no trusted setup. Bulletproofs remain relevant for specialized use cases like confidential transactions, and PLONK has enabled widespread deployment through its universal trusted setup. The ongoing research and development in this space promise continued improvements in performance, security, and usability. + +Major blockchain implementations including zkSync Era, StarkNet, Polygon zkEVM, and Scroll have demonstrated that ZK rollups can achieve practical deployment at scale. Each project has made different trade-offs between compatibility, performance, and decentralization, creating a healthy ecosystem of options for developers. The technical advances in 2025, particularly StarkNet's S-two prover and decentralized sequencing, have substantially improved the practical viability of ZK-based systems. The continued progress toward full decentralization and interoperability suggests an increasingly mature technology stack. + +The Rust ecosystem provides robust foundations for ZKP development, with libraries like arkworks, Bellman, and Halo2 addressing different needs within the development community. The combination of Rust's safety guarantees, extensive cryptographic libraries, and active open-source communities positions Rust as a leading language for ZKP application development. As the technology continues to evolve, the ecosystem will likely see further consolidation around the most successful approaches while new innovations emerge to address evolving requirements. + +## 8.

The investigation reveals a vibrant and rapidly evolving landscape of AI implementations within the Cairo ecosystem, ranging from neural network implementations to comprehensive provable machine learning frameworks. The S-two prover represents a significant advancement in enabling AI verification capabilities within the Cairo ecosystem, offering unprecedented performance for zero-knowledge proof generation related to machine learning workloads. + +## 1. Introduction and Background + +Cairo is a Turing-complete programming language developed by StarkWare that serves as the native language for StarkNet, Ethereum's Layer 2 scaling solution. Originally designed for creating provable programs for general computation, Cairo has evolved to become a powerful platform for zero-knowledge proof generation, with significant implications for artificial intelligence applications. The language abstracts away the complex cryptography and mathematics involved in proof generation, allowing developers to focus on building applications while the underlying STARK (Scalable Transparent ARguments of Knowledge) cryptographic infrastructure handles the proving mechanism. + +The intersection of Cairo with AI represents a relatively new but rapidly developing field, driven primarily by the need for verifiable and privacy-preserving machine learning. Zero-knowledge machine learning (ZKML) enables the verification of ML model execution without revealing the underlying model weights or input data, creating new possibilities for trustless AI applications. This research investigates the current state of AI implementations within the Cairo ecosystem, examines the feature enabling aspects of the S-two prover, and provides a comprehensive feature matrix for comparative analysis. + +## 2. Cairo AI Ecosystem Overview + +### 2.1 Foundational AI Frameworks + +The Cairo ecosystem has developed several specialized frameworks and tools for AI and machine learning applications. The most prominent among these is Orion, an open-source, community-driven framework dedicated to provable machine learning. Developed by Gizatech, Orion provides essential components for building verifiable ML models and implements an ONNX Runtime in Cairo 1.0 for executing machine learning inference with cryptographic proof verification through STARKs. + +Orion represents a significant milestone in democratizing access to verifiable machine learning, enabling developers to train models in mainstream frameworks such as TensorFlow or PyTorch and then execute them with verifiable inference on StarkNet. The framework leverages the ONNX (Open Neural Network Exchange) format as a universal intermediary, ensuring compatibility with the broader deep learning ecosystem. This approach allows organizations to maintain their existing ML workflows while gaining the ability to generate cryptographic proofs of correct inference execution. + +The framework is structured around three primary components: the Framework itself providing building blocks for verifiable machine learning models, the Hub offering a curated collection of community-built ML models and demonstration spaces, and the Academy providing educational resources and tutorials for developers seeking to build ValidityML applications. As of March 2025, the original Orion project has been archived, with the development team transitioning to work on LuminAIR, a new zkML framework based on custom AIR (Algebraic Intermediate Representation) proven with the S-two Prover. + +### 2.2 Neural Network Implementations + +Several notable neural network implementations exist within the Cairo ecosystem, demonstrating the practical applicability of machine learning models on the platform. The neural-network-cairo project provides a complete neural network implementation from scratch for MNIST digit classification, written entirely in Cairo 1.0. This implementation features a two-layer architecture with 784 input units corresponding to the 28×28 pixel images, a hidden layer with 10 units using ReLU activation, and an output layer with 10 units using softmax activation for digit classification. + +The implementation includes sophisticated features such as 8-bit weight quantization based on ONNX quantization standards, various data structure implementations including vectors, matrices, and tensors with associated operations, forward propagation capabilities, and methods for loading pre-trained weights from TensorFlow models into Cairo neural networks. This project demonstrates the feasibility of running practical machine learning inference on blockchain infrastructure while maintaining verifiability guarantees. + +Additional AI demonstrations within the ecosystem include Tic-Tac-Stark, which implements a provable Tic-Tac-Toe AI model using Orion and Cairo, and drive-ai, a self-driving car AI project built on the Dojo game engine. These projects, while more experimental in nature, demonstrate the versatility of Cairo for different AI application domains and serve as proof-of-concept implementations for more sophisticated future applications. + +## 3. Zero-Knowledge Machine Learning Applications + +### 3.1 Cairo Verifier and ZKML Capabilities + +The Cairo Verifier deployed on StarkNet represents a transformative advancement for zero-knowledge machine learning applications. The verifier enables STARK proofs to be verified directly on StarkNet smart contracts, providing substantially cheaper verification costs compared to Ethereum mainnet verification. This cost efficiency is essential for making ZKML applications economically viable, as the computational overhead of proof verification has historically been a significant barrier to adoption. + +The technical architecture of the Cairo Verifier features a single contract design, unlike Ethereum's Solidity verifier which is split across dozens of separate contracts. This monolith architecture improves auditability and reduces the complexity of integration for developers. The verifier supports bootloader programs that reduce verifier complexity without revealing entire bytecode, flexible hash functions including Poseidon, Blake, and Keccak for optimization trade-offs between prover and verifier costs, and various Cairo layouts with different builtin combinations. + +The enablement of client-side proving represents a particularly powerful capability for ZKML applications. Machine learning computations can be proven locally on client devices and verified on-chain, creating a privacy-preserving workflow where sensitive input data never leaves the client while still providing cryptographic guarantees of correct execution. This architecture supports the verification of model outputs without revealing model weights, enabling scenarios such as proving that a credit risk assessment was generated by a specific model without exposing the proprietary model parameters. + +### 3.2 ZKML Use Cases and Applications + +Zero-knowledge machine learning enabled by Cairo encompasses a broad range of practical applications across multiple industries. The technology enables verification of AI model outputs in decentralized contexts, allowing smart contracts to depend on AI-generated decisions while maintaining cryptographic certainty about the correctness of those decisions. This capability is particularly valuable for DeFi applications requiring credit scoring, risk assessment, or automated decision-making that benefits from verifiability guarantees. + +Privacy-preserving inference represents another significant application domain, where ZKML enables proving the correctness of ML inference without revealing the underlying input data. This capability addresses regulatory compliance requirements in sectors such as healthcare and finance, where sensitive data processing must be combined with strong privacy guarantees. The technology also enables verifiable random forests and other ensemble methods, where the integrity of complex voting-based predictions can be cryptographically verified. + +The integration with the broader StarkNet ecosystem enables sophisticated multi-party computation scenarios where different participants can contribute to ML inference while maintaining confidentiality over their respective inputs. This capability opens possibilities for collaborative machine learning on blockchain infrastructure, where multiple organizations can jointly evaluate models on combined datasets without exposing individual data contributions. + +## 4. S-two Prover and AI Feature Enablement + +### 4.1 Technical Architecture and Performance + +The S-two prover (stwo-cairo) represents StarkWare's next-generation zero-knowledge proving system, described as the fastest prover in the world. The prover is fully open-source and written in Rust, implementing the Circle STARK protocol—a breakthrough proving system over 31-bit chip-friendly Mersenne prime field. The technical architecture supports multiple hardware backends including CPU, SIMD, and GPU, with WebGPU and WASM compilation for in-browser proving capabilities scheduled for future release. + +The performance characteristics of S-two are particularly relevant for AI applications, with benchmarks demonstrating 28X faster performance than Risc0 precompile on Keccak chain and 39X faster than SP1 precompile on equivalent benchmarks. The prover achieves 10-30X performance gains depending on the specific task compared to alternative solutions. These performance improvements are attributable to the use of high-level general-purpose language (Cairo) rather than low-level hand-tuned circuits, combined with the mathematical innovations of the Circle STARK protocol. + +The S-two prover architecture supports recursive proving out of the box, enabling complex proof compositions that are essential for sophisticated AI verification workflows. The compatible Cairo programming language provides a familiar development environment for developers building AI applications, while the prover's client-side capabilities enable practical deployment scenarios where proof generation occurs on consumer hardware including phones, laptops, and browser tabs. + +### 4.2 AI-Specific Capabilities + +S-two includes specific features designed to address AI verification needs, categorized into four primary capability areas. Model authenticity verification enables proving that a known model produced a given output, addressing concerns about adversarial substitution of ML models in production systems. This capability ensures that on-chain applications can verify they are interacting with the intended model rather than a modified version. + +Input integrity verification provides mechanisms to prove what inputs were used in a computation without revealing those inputs, essential for privacy-preserving AI applications. This capability enables scenarios where the existence and correctness of specific input data can be demonstrated without exposing the actual data values, creating powerful primitives for privacy-sensitive applications. + +zkML inference enables running provable inference locally with proofs verified on-chain, bringing zero-knowledge capabilities to standard machine learning workflows. The practical feasibility of generating proofs of ML inference on real-world hardware represents a significant advancement for the field, making it economically viable to deploy verifiable AI in production systems. AI automation capabilities enable triggering on-chain actions based on verifiable AI outcomes, closing the loop between off-chain AI inference and on-chain execution. + +### 4.3 Integration with Cairo Ecosystem + +The integration of S-two with the broader Cairo ecosystem creates a comprehensive platform for AI application development. The prover is accessible through the Scarb build tool via the `scarb prove` command (requires Scarb version 2.10.0 or later), providing a seamless developer experience for building and proving Cairo programs. The dual crate architecture separates prover and verifier implementations, enabling optimized deployment strategies based on specific application requirements. + +The availability of S-two as an open-source project (272 stars, 60 forks, 1,199 commits) ensures community engagement and transparency in the proving infrastructure. The expected on-chain verifier deployment on StarkNet by the end of 2025 will further enhance the accessibility of these capabilities for production AI applications, enabling direct on-chain verification of proofs generated by the S-two prover. + +## 5. Feature Matrix Analysis + +The following feature matrix provides a comparative analysis of the key AI-related capabilities across the Cairo ecosystem components: + +| Feature Category | Cairo Language | Orion Framework | S-two Prover | Cairo Verifier | +| ------------------------ | --------------- | ------------------ | ------------- | ----------------- | +| **ML Framework** | | | | | +| Neural Network Support | Basic | Advanced | N/A | N/A | +| ONNX Runtime | Via External | Native | N/A | N/A | +| Model Training | Not Supported | Limited | N/A | N/A | +| Pre-trained Model Import | Via Manual Port | Automatic (ONNX) | N/A | N/A | +| **Proving Capabilities** | | | | | +| STARK Proof Generation | Native | Via Framework | Native | N/A | +| ZK Proof Support | Native | Native | Native | Verification Only | +| Recursive Proving | Via Libraries | Via Libraries | Native | Limited | +| Client-side Proving | Not Native | Not Native | Native | N/A | +| **AI Verification** | | | | | +| Model Authenticity | Manual | Via Framework | Native | Supported | +| Input Integrity | Manual | Via Framework | Native | Supported | +| Output Verification | Manual | Via Framework | Via Proof | Supported | +| Privacy Preservation | Manual | Via Framework | Native | Supported | +| **Performance** | | | | | +| Proof Generation Speed | Standard | Standard | 28-39X Faster | N/A | +| Verification Cost | High | Medium | Low | Low (L2) | +| Hardware Acceleration | No | No | CPU/SIMD/GPU | N/A | +| Browser Support | No | No | Coming Soon | N/A | +| **Development** | | | | | +| Language | Cairo 1.0 | Cairo 1.0 | Rust/Cairo | Cairo | +| Framework Integration | N/A | TensorFlow/PyTorch | N/A | N/A | +| Documentation | Comprehensive | Good | Good | Good | +| Maintenance Status | Active | Archived | Active | Active | + +### 5.1 Feature Matrix Interpretation + +The feature matrix reveals distinct specializations among the ecosystem components. Cairo language provides the foundational programming model and native STARK proof generation capabilities, serving as the substrate upon which higher-level AI tools are built. The language itself supports basic neural network operations through manual implementation but does not provide integrated ML framework capabilities. + +The Orion framework delivers the most comprehensive ML-specific feature set, including native ONNX runtime support, automatic model import from standard frameworks, and built-in mechanisms for verifiable inference. However, its archived status as of March 2025 raises questions about long-term maintenance and suggests that the ecosystem may be transitioning toward newer solutions. + +The S-two prover represents the performance leader in the ecosystem, providing native support for all key AI verification capabilities including model authenticity, input integrity, and privacy-preserving inference. Its hardware acceleration support and client-side proving capabilities position it as the preferred solution for production AI applications requiring high throughput and low latency. + +The Cairo Verifier provides essential on-chain verification capabilities at substantially reduced costs compared to Ethereum mainnet alternatives. Its support for client-side proving enables the privacy-preserving ZKML workflows that are essential for many practical applications. + +## 6. Practical Applications and Use Cases + +### 6.1 Current Implementations + +The practical applications of Cairo-based AI span multiple domains and complexity levels. The MNIST digit recognition implementation demonstrates the feasibility of running conventional machine learning inference on blockchain infrastructure, providing a template for more sophisticated image classification applications. The Tic-Tac-Toe AI demonstrates game AI with provable correctness guarantees, illustrating how AI decision-making can be verified in adversarial settings. + +The Dojo-based drive-ai project extends AI applications into simulation and gaming domains, leveraging the provable game engine to create verifiable autonomous agent behaviors. These early implementations serve as proof-of-concept demonstrations that establish the technical viability of more ambitious future applications. + +### 6.2 Emerging Applications + +The combination of S-two prover capabilities with Cairo's programming model enables several emerging application categories. Verifiable AI agents can operate autonomously on-chain while providing cryptographic proof of their decision-making processes, enabling trustless automation of complex financial and organizational tasks. The integration with AI agents enables on-chain actions to be triggered based on verifiable AI outcomes, creating closed-loop systems where off-chain intelligence drives on-chain execution. + +Proof of humanity and identity applications leverage ZKML capabilities to verify human characteristics without revealing biometric data, addressing concerns about bot proliferation while maintaining privacy. Age verification and zkKYC (zero-knowledge Know Your Customer) represent additional application domains where AI classification must be combined with privacy-preserving verification mechanisms. + +Decentralized identity systems benefit from ZKML capabilities through verifiable credentials that demonstrate possession of certain attributes without revealing the underlying evidence. Proof of uniqueness systems enable demonstration of personhood without revealing specific identity, addressing Sybil attack concerns in governance and allocation systems while preserving anonymity. + +## 7. Conclusion + +The Cairo ecosystem has developed a comprehensive suite of tools and frameworks for AI applications, with particular strength in zero-knowledge machine learning and verifiable AI systems. The combination of the Cairo programming language, Orion framework (and its successor LuminAIR), S-two prover, and Cairo Verifier creates a complete platform for developing, deploying, and verifying AI applications on blockchain infrastructure. + +The S-two prover represents a significant advancement in enabling practical AI verification, with performance characteristics that make client-side proof generation viable on consumer hardware. Its specific capabilities for model authenticity, input integrity, and privacy-preserving inference directly address the requirements of production AI applications. + +The ecosystem continues to evolve, with the transition from Orion to LuminAIR indicating ongoing development activity. The expected deployment of on-chain verification for S-two proofs on StarkNet by the end of 2025 will further enhance the accessibility of these capabilities for mainstream applications. + +For organizations seeking to build verifiable or privacy-preserving AI applications on blockchain infrastructure, the Cairo ecosystem provides a mature and well-documented platform. The key considerations include selecting appropriate tools based on specific requirements (performance, privacy, verification needs), monitoring the transition from Orion to LuminAIR for updated capabilities, and leveraging client-side proving capabilities for privacy-sensitive applications. + +## 8.

This niche emphasizes inference accessibility, timezone arbitrage, and seamless integration for AI devs — differentiating from broader compute markets by being AI-specific, user-centric, and low-barrier. To compete head-on with each project's strengths, CipherOcto should lean into its strengths: drop-in compatibility (OpenAI proxy), cost normalization across providers, reputation/slashing for trust, and early contributor multipliers for rapid liquidity. +Vs. Bittensor (TAO): Best at Collaborative ML Incentives & Subnet Specialization +Bittensor excels in creating a global, incentivized "brain" where miners contribute specialized ML models/subnets (e.g., for text gen or predictions), validated via "Proof of Intelligence" for quality rewards. +Positioning to compete: CipherOcto should highlight its own agent-driven, reputation-based marketplace as a "subnet for inference quotas" — allowing devs to contribute/sell idle API access as micro-subnets, with slashing for poor quality (e.g., timeouts/garbage responses) mirroring Bittensor's validation. Differentiate by focusing on immediate, low-effort participation (list spare quotas vs. running full models) and multi-provider normalization (e.g., equating GPT-4 to Claude units) for easier cross-model routing. Market as "Bittensor for quick AI access" to attract devs who want rewards without heavy ML ops. +Vs. Akash (AKT): Best at Permissionless Cloud/GPU Rental & Cost Savings +Akash dominates as a decentralized AWS alternative, with reverse auctions for leasing global hardware (CPUs/GPUs) at 50–90% lower costs, emphasizing scalability for any workload. +Positioning to compete: Emphasize CipherOcto's quota trading as "Akash for AI APIs" — a spot market for burst inference capacity (e.g., buy 1000 GPT prompts at auction-like prices) without provisioning servers. Compete on cost by enabling timezone arbitrage (e.g., US dev sells idle quota to Asian users) and auto-recharge policies for seamless scaling. Differentiate via AI-specific ergonomics: local proxies for zero-downtime routing, no hardware setup (just share API keys securely), and OCTO-W as metered credits — positioning as faster/cheaper for inference-only workloads vs. Akash's general compute. +Vs. Gensyn: Best at Aggregating Idle Hardware for ML Training +Gensyn shines in trustless ML training on distributed idle devices (GPUs, CPUs, even mobiles), with verification to ensure honest computation and massive cost reductions for large-scale models. +Positioning to compete: CipherOcto should frame itself as "Gensyn for inference" — aggregating idle API quotas (not hardware) for on-demand prompting, with future ZK proofs (as teased in docs) for verifiable responses. Compete by targeting inference-heavy devs (e.g., agent builders needing quick queries) where training isn't the bottleneck, offering lower latency via proxied APIs vs. Gensyn's distributed training delays. Differentiate with developer bootstrapping: early multipliers for quota contributors to build liquidity faster than Gensyn's hardware-focused network effects. +Vs. Ritual: Best at On-Chain AI Composability & Inference for dApps +Ritual leads in embedding AI directly into blockchains — enabling smart contracts/dApps to call models natively, with modular verification, privacy, and governance for composable AI (e.g., DeFi oracles with ML). +Positioning to compete: Position CipherOcto as "Ritual's off-ramp for real-world devs" — a hybrid layer where quota routers integrate with on-chain calls (e.g., swap OCTO-W via Starknet for Ritual-like composability). Compete on composability by evolving agent policies to support custom on-chain triggers (e.g., auto-route prompts based on blockchain events), with TEE/ZK for privacy matching Ritual's. Differentiate via standalone utility: no blockchain required for basic quota trading, plus multi-provider support (OpenAI + Anthropic) for broader access than Ritual's chain-specific focus. +Overall Strategy Recommendations + +Core differentiation: Double down on "frictionless bootstrapping" — CipherOcto's local router + quota flywheel (contribute idle → earn → buy more) lowers barriers compared to competitors' hardware/ML expertise needs. Use multipliers to hit 100 early contributors fast, creating network effects. +Marketing angle: Pitch as the "developer-first deAI gateway" — easier than Bittensor/Akash for quick wins, complementary to Gensyn/Ritual for inference (partner/integrate where possible, e.g., route to Ritual on-chain). +Roadmap leverage: Accelerate ZK/TEE for privacy/verification to close gaps with Gensyn/Ritual; expand to raw compute trading post-MVE to nibble at Akash. +Metrics for success: Aim for 1M OCTO-W volume in Month 1 (per use-case doc) by undercutting competitors' costs 20–30% via arbitrage. + +LuminAIR specializes in verifiable ML computations — cryptographically proving that a machine learning model (inference or forward pass) executed correctly using Circle STARK proofs powered by StarkWare's S-two (STWO) prover, often with Cairo programs for on-chain verification on Starknet. + +Positioning Options for CipherOcto + +1. Get Inspiration (Recommended Starting Point – Low Effort, High Value) + LuminAIR / Giza's approach offers several concrete ideas CipherOcto can borrow without any partnership: + +Privacy upgrade path +CipherOcto's biggest current limitation is the trust assumption that sellers see prompt content when proxying requests. +→ Draw inspiration from zkML techniques to explore future-proofing with selective disclosure or encrypted prompts. Even if full ZK inference is too heavy for MVE, reference LuminAIR's Circle STARKs + STWO as a north star for eventual "provable clean routing" or "ZK proof of correct proxy execution without revealing prompt". +Verifiable quality / disputes +In RFC-0900 disputes (garbage response, failed inference), CipherOcto relies on automated signals + reputation. +→ Take cues from LuminAIR's proof-of-correct-execution to design lightweight proofs for "the model produced a valid output shape/latency" or integrate STWO-based verification for high-stake routes in Phase 2/3. +Starknet / Cairo alignment +CipherOcto's RFC-0102 (Numeric/Math) already chooses Starknet ECDSA, Poseidon hashing, and Cairo-compatible structures. +→ This makes future integration technically natural. Use LuminAIR as inspiration to make quota proofs verifiable on Starknet (e.g., prove that X prompts were routed correctly and burned OCTO-W). +Agent verifiability +As both projects target autonomous agents, borrow the "verifiable intelligence" narrative: position CipherOcto's quota router as the access layer that feeds into verifiable execution layers like LuminAIR. + +2. Partnering / Integration (Medium-Term Opportunity) + A natural symbiosis exists, especially given shared Starknet ecosystem affinity: + +CipherOcto as the "data & access frontend" for LuminAIR agents +Verifiable agents (e.g., DeFi trading bots, autonomous recommenders) built on LuminAIR need reliable, cheap, burstable inference. CipherOcto can become the decentralized quota provider/routing layer that these agents call — e.g., a router policy that prefers "verifiable" routes when available. +Joint use-case: zk-proved quota usage +In the future, prove on-chain (via STWO + Cairo verifier) that a certain number of prompts were successfully routed/executed without revealing content — useful for OCTO-W burn transparency or dispute resolution. +Co-marketing in Starknet / deAI ecosystem +Both projects are early, Starknet-aligned, and agent-focused. A loose collaboration (e.g., "LuminAIR agents powered by CipherOcto quota routing") could help both bootstrap adoption. + +3. Against / Competitive Framing (Only If Forced) + Avoid direct "vs" framing — it's not apples-to-apples. If pressed: + +CipherOcto wins on immediate utility & developer onboarding (drop-in OpenAI proxy, earn from idle quota today). +LuminAIR wins on cryptographic trust & on-chain composability (verifiable outputs for smart contracts). +Position CipherOcto as complementary: "We get you the inference cheaply & scalably — LuminAIR proves it happened correctly." + +Bottom line recommendation (March 2026) +Start with inspiration — study LuminAIR's STWO integration, AIR design, and Cairo verifier patterns to roadmap your privacy & dispute upgrades (e.g., in reputation-system or custom-policy-engine missions). +Once MVE is live and you have real routing volume, reach out to Giza (they're active on X @gizatechxyz and open-source friendly) for potential integration discussions — especially around verifiable agents in DeFi or web3. The overlap in Starknet tooling makes this one of the more realistic and high-upside partnerships in the current deAI landscape. diff --git a/docs/research/stoolap-agent-memory-gap-analysis.md b/docs/research/stoolap-agent-memory-gap-analysis.md new file mode 100644 index 0000000..2e0d6ff --- /dev/null +++ b/docs/research/stoolap-agent-memory-gap-analysis.md @@ -0,0 +1,1200 @@ +# Stoolap → Agent Memory: Feature Gap Analysis + +> **Strategic Analysis: Evolving Stoolap from SQL Database to Verifiable Agent Memory System** + +**Date:** 2026-03-09 +**Version:** 1.0 +**Status:** Strategic Planning + +--- + +## Executive Summary + +**CipherOcto is building Stoolap as its memory infrastructure**, but there is a significant gap between Stoolap's current capabilities (embedded SQL database with ZK proofs) and the requirements for a production-grade Agent Memory system. + +### Key Finding + +**Stoolap has ~40% of the foundational components for Agent Memory**, but lacks the critical higher-level memory abstractions, lifecycle management, and agent-specific features that systems like Mem0, Zep/Graphiti, and Letta/MemGPT provide. + +| Category | Stoolap Current | Agent Memory Required | Gap | +| ----------------------- | -------------------------------- | -------------------------------------- | ----------- | +| **Storage Engine** | ✅ Complete (MVCC, WAL, Indexes) | Same | ✅ None | +| **Vector Search** | ✅ Complete (HNSW) | Same | ✅ None | +| **Verifiable State** | ✅ Complete (Merkle, ZK) | Same | ✅ None | +| **Memory Abstractions** | ❌ None | Episodic, Semantic, Procedural | 🔴 Critical | +| **Memory Lifecycle** | ❌ None | Consolidation, Compression, Forgetting | 🔴 Critical | +| **Agent Identity** | ⚠️ Partial | Agent-scoped memory, Ownership | 🟡 High | +| **Memory Operations** | ⚠️ Partial | Smart retrieval, Ranking, Reflection | 🟡 High | +| **Multi-Modal** | ❌ None | Video, Audio, Image memory | 🟡 Medium | +| **Benchmarks** | ❌ None | LongMemEval, BEAM, MOOM | 🟢 Low | + +**Overall Gap Analysis:** + +- ✅ **Foundational Layer (60% complete)**: Storage, indexing, vector search, verification +- 🔴 **Memory Layer (0% complete)**: Abstractions, lifecycle, operations +- 🟡 **Agent Layer (20% complete)**: Identity, multi-agent sharing, ownership + +--- + +## Table of Contents + +1.

It remains at 0104 as it belongs to the Numeric/Math category. + +## Summary + +This RFC introduces Deterministic Floating-Point (DFP) — a numeric abstraction that provides floating-point developer ergonomics while guaranteeing bit-identical execution across all nodes participating in CipherOcto consensus. DFP enables floating-point arithmetic in blockchain state transitions and deterministic query execution without sacrificing reproducibility. + +The design introduces a two-tier numeric model: non-deterministic FLOAT/DOUBLE for analytics, and deterministic DFP for consensus-critical computations. Type mixing requires explicit casting to prevent ambiguous semantics. + +> ⚠️ **EXPERIMENTAL WARNING**: DFP consensus usage is **experimental and carries high technical risk**. Most production blockchains avoid floating-point in consensus paths entirely. DFP should be considered **alpha-stage technology** until: +> +> - Hardware verification is proven robust over years of production +> - Comprehensive test vectors are validated across architectures +> - Transcendental functions (Mission 1b) are implemented +> - Real-world benchmarks demonstrate acceptable performance +> +> **Recommendation**: Start with software-only path.

Platform Word Size + +**Hazard:** 32-bit, 64-bit, and 128-bit native integers can cause implicit widening/narrowing inconsistencies. + +**Mitigation:** Explicitly define all numeric widths: + +``` +mantissa: i128 +exponent: i32 +``` + +##### 6. Endianness + +**Hazard:** Little vs big endian can misinterpret serialized values. + +**Mitigation:** Use fixed byte order (little-endian) in serialization: + +``` +struct { int128 mantissa, int32 exponent } +``` + +##### 7. Non-Deterministic Math Libraries + +**Hazard:** Standard math libraries (libm, libc) use platform-specific implementations for sqrt(), pow(), exp(). + +**Mitigation:** All mathematical operations must be implemented within the DFP library itself. + +##### 8. Parallel Execution + +**Hazard:** Parallel reductions and SIMD can change evaluation order. + +**Mitigation:** DFP arithmetic must execute in deterministic sequential order with fixed reduction trees. + +##### 9.

verified AI inference replaces traditional hash computation as the primary work securing the network. Instead of miners performing meaningless SHA256 hashing, nodes perform deterministic AI-VM inference tasks whose correctness is verified via STARK proofs. The system ensures AI computation equals consensus work, transforming the network into a global distributed AI compute system. + +## Design Goals + +| Goal | Target | Metric | +|

Draft +**Submission Date:** 2026-03-10 + +> **Note:** This RFC was renumbered from RFC-0149 to RFC-0303 as part of the category-based numbering system. + +## Summary + +This RFC defines HNSW-D, a deterministic version of the Hierarchical Navigable Small World (HNSW) vector index suitable for consensus execution. The index supports efficient approximate nearest neighbor (ANN) search over vectors stored in the CipherOcto vector storage engine. + +Standard HNSW implementations are nondeterministic due to random level assignment, concurrent graph updates, floating-point distance, and nondeterministic traversal ordering. HNSW-D removes these sources of nondeterminism by defining deterministic level assignment, canonical graph insertion, deterministic search ordering, deterministic tie-breaking, and fixed-point distance metrics. + +## Design Goals + +| Goal | Target | Metric | +| ---- | ---------------- | ------------------------------------------- | +| G1 | Determinism | Identical graph structures across all nodes | +| G2 | Consensus Safety | Deterministic graph edges from same dataset | +| G3 | Efficient Search | O(log N) similar to standard HNSW | +| G4 | ZK Compatibility | Distance via RFC-0106 primitives | + +## Motivation + +Vector similarity search is essential for: + +- AI retrieval-augmented generation (RAG) +- Semantic embedding search +- Agent memory layers +- Recommendation systems + +Current blockchain vector indexes lack determinism.
