Challenge-Based / Lazy Checkpoints + +**How it works:** Don't require regular checkpoints. Instead, anyone can challenge a provider at any time.

Changes: - Create file-system-primitives crate with protobuf schemas - DirectoryNode: stores directory structure with child references - FileManifest: tracks file chunks and metadata - DriveInfo: on-chain drive metadata (owner, bucket, root CID) - Helper functions for CID computation and serialization - Implement pallet-drive-registry for on-chain drive management - Multi-drive support: users can create multiple drives per account - Extrinsics: create_drive, update_root_cid, delete_drive, update_drive_name - Storage: Drives (DriveId → DriveInfo), UserDrives (Account → Vec) - Events: DriveCreated, RootCIDUpdated, DriveDeleted, DriveNameUpdated - 13 comprehensive tests all passing Architecture: - Layer 1 (On-Chain): Registry stores DriveId → root CID mapping - Layer 0 (Off-Chain): Metadata blobs stored in buckets as protobuf - DAG traversal: root CID → DirectoryNode → child CIDs → files/dirs - Immutable versioning: Each root CID = snapshot of drive state Key design decisions: - Names stored in parent (optimal for renames) - Multi-drive per account (flexible) - BoundedVec for names (MaxEncodedLen compliance) - DriveId auto-increment counter Tests: All passing (5 primitive tests + 13 pallet tests) --- Cargo.toml | 4 + client/src/bin/demo_upload.rs | 18 +- file-system-primitives/Cargo.toml | 34 ++ file-system-primitives/build.rs | 4 + file-system-primitives/proto/filesystem.proto | 40 +++ file-system-primitives/src/lib.rs | 336 +++++++++++++++++ pallet-drive-registry/Cargo.toml | 37 ++ pallet-drive-registry/src/lib.rs | 334 +++++++++++++++++ pallet-drive-registry/src/mock.rs | 67 ++++ pallet-drive-registry/src/tests.rs | 340 ++++++++++++++++++ 10 files changed, 1207 insertions(+), 7 deletions(-) create mode 100644 file-system-primitives/Cargo.toml create mode 100644 file-system-primitives/build.rs create mode 100644 file-system-primitives/proto/filesystem.proto create mode 100644 file-system-primitives/src/lib.rs create mode 100644 pallet-drive-registry/Cargo.toml create mode 100644 pallet-drive-registry/src/lib.rs create mode 100644 pallet-drive-registry/src/mock.rs create mode 100644 pallet-drive-registry/src/tests.rs diff --git a/Cargo.toml b/Cargo.toml index 3e1e08e..31c5fc8 100644 --- a/Cargo.toml +++ b/Cargo.toml @@ -6,6 +6,8 @@ members = [ "provider-node", "client", "runtime", + "file-system-primitives", + "pallet-drive-registry", ] [workspace.package] @@ -18,9 +20,11 @@ repository = "https://github.com/parity/scalable-web3-storage" # Internal crates storage-primitives = { path = "primitives", default-features = false } pallet-storage-provider = { path = "pallet", default-features = false } +pallet-drive-registry = { path = "pallet-drive-registry", default-features = false } storage-provider-node = { path = "provider-node" } storage-client = { path = "client" } storage-parachain-runtime = { path = "runtime" } +file-system-primitives = { path = "file-system-primitives", default-features = false } # Substrate frame frame-executive = { git = "https://github.com/paritytech/polkadot-sdk", tag = "polkadot-stable2512", default-features = false } diff --git a/client/src/bin/demo_upload.rs b/client/src/bin/demo_upload.rs index 9dbdf00..ac21984 100644 --- a/client/src/bin/demo_upload.rs +++ b/client/src/bin/demo_upload.rs @@ -29,22 +29,23 @@ async fn main() -> Result<(), Box> { let args: Vec = std::env::args().collect();

c2700484b245ba7147aad23dab6e3398ecb18f8c Mon Sep 17 00:00:00 2001 From: Naren Mudigal Date: Wed, 4 Feb 2026 17:13:29 +0000 Subject: [PATCH 03/48] feat: implement Layer 1 file system with multi-drive support - Add file-system-primitives crate with protobuf schemas - DirectoryNode: Protobuf-serialized directory structure - FileManifest: File metadata with chunk references - DriveInfo: On-chain drive metadata (owner, bucket, root CID) - CID computation using blake2-256 - Add pallet-drive-registry for drive management - create_drive: Register new drive with bucket and root CID - update_root_cid: Update drive after file system changes - delete_drive: Remove drive - update_drive_name: Rename drive - Multi-drive per account support - UserDrives storage for tracking user's drives - Organize in storage-interfaces/file-system/ structure - Separates Layer 0 (storage primitives) from Layer 1 (interfaces) - Clear hierarchy: storage-interfaces/file-system/{primitives,pallet-registry} - Comprehensive README with architecture, data flow, and examples --- Cargo.toml | 15 +- storage-interfaces/file-system/README.md | 212

Protobuf-serialized directory with child references +- `FileManifest`: File metadata and chunk references +- `DriveInfo`: On-chain drive metadata (owner, bucket, root CID) +- `Cid`: Content identifier (blake2-256 hash) + +**Features:** +- Protobuf schemas for efficient serialization +- CID computation and manipulation +- DAG helper functions + +### `pallet-registry/` +On-chain registry pallet for drive management. + +**Extrinsics:** +- `create_drive(bucket_id, root_cid, name)` - Create new drive +- `update_root_cid(drive_id, new_root_cid)` - Update after file system changes +- `delete_drive(drive_id)` - Remove drive +- `update_drive_name(drive_id, name)` - Rename drive + +**Storage:** +- `Drives: DriveId → DriveInfo` - Drive registry +- `UserDrives: AccountId → Vec` - User's drives +- `NextDriveId: u64` - Auto-incrementing counter + +**Features:** +- Multi-drive support (multiple drives per account) +- Immutable versioning (each root CID = snapshot) +- Event emission for all operations + +## Data Flow + +### Writing a File + +``` +1. Client splits file into chunks + └─> Upload chunks to Layer 0 bucket + +2. Client creates FileManifest + └─> Serialize with protobuf + └─> Upload to Layer 0 bucket (get file_cid) + +3. Client updates parent DirectoryNode + └─> Add DirectoryEntry { name: "file.txt", cid: file_cid, ... } + └─> Serialize and upload (get new_parent_cid) + +4. Client recursively updates parents up to root + └─> Generate new root_cid + +5. Client calls update_root_cid(drive_id, new_root_cid) + └─> On-chain update (creates new snapshot) +``` + +### Reading a File + +``` +1. Query on-chain: get_drive_root_cid(drive_id) + └─> Returns root_cid + +2. Fetch from Layer 0: GET /node?hash=root_cid + └─> Deserialize DirectoryNode (root /) + +3. Traverse path: /documents/report.pdf + └─> Find "documents" → get documents_cid + └─> Fetch documents_cid → DirectoryNode + └─> Find "report.pdf" → get report_cid + +4. Fetch FileManifest: GET /node?hash=report_cid + └─> Get list of chunk CIDs + +5. Fetch and reconstruct file from chunks +``` + +## Design Decisions + +### Why Names in Parent? +Storing entry names in the parent DirectoryNode (not in the child) optimizes renames: +- Renaming only changes parent blob +- Child CID stays stable (good for caching) +- Minimal cascade (only path from changed dir → root) + +### Why Multi-Drive Per Account? +Flexibility for different use cases: +- Personal vs Work drives +- Public vs Private drives +- Different storage providers per drive +- Easier access control management + +### Why Immutable Versioning? +Each root CID represents a complete snapshot: +- "Time machine" capability (access any historical state) +- Audit trail of all changes +- Easy rollback to previous versions +- Compatible with IPFS/IPLD patterns + +## Usage Example + +```rust +use file_system_primitives::{DirectoryNode, FileManifest, compute_cid}; +use pallet_drive_registry::Pallet as DriveRegistry; + +// Create empty drive +let root = DirectoryNode::new_empty("drive_1"); +let root_cid = root.compute_cid()?; +let root_bytes = root.to_bytes()?; + +// Upload root to Layer 0 +provider_client.upload(bucket_id, &root_bytes).await?; + +// Register drive on-chain +DriveRegistry::create_drive( + origin, + bucket_id, + root_cid, + Some(b"My Drive".to_vec()) +)?; +``` + +## Testing + +```bash +# Test primitives +cargo test -p file-system-primitives + +# Test pallet +cargo test -p pallet-drive-registry + +# Run all Layer 1 tests +cargo test -p file-system-primitives -p pallet-drive-registry +``` + +## Future Work + +### Planned Features (File System Interface) +- [ ] Client SDK for high-level file operations +- [ ] DAG builder and traversal utilities +- [ ] Path resolution helpers +- [ ] Batch operations (multiple file changes → single root update) +- [ ] Indexer service (off-chain metadata indexing) +- [ ] Search API (full-text search on file names/metadata) + +### Layer 2 Integration (Future) +- [ ] FUSE driver for local mounting +- [ ] Web dashboard (Google Drive-like UI) +- [ ] CLI tools (ls, cp, mv, rm) +- [ ] WebDAV server +- [ ] Access control (W3ACL/UCAN integration) + +## References + +- [Layer 1 Design Doc](../../docs/design/layer-1-file-system.md) _(to be created)_ +- [Three-Layered Architecture](../../docs/design/scalable-web3-storage.md) +- [Layer 0 Implementation](../../docs/design/scalable-web3-storage-implementation.md) +- [Protobuf Schemas](./primitives/proto/filesystem.proto) + +## Contributing + +When adding new features to the File System Interface: +1.

Ensure Runtime Configuration + +Check that the runtime has proper configuration in `runtime/src/lib.rs`: + +```rust +impl pallet_drive_registry::Config for Runtime { + type RuntimeEvent = RuntimeEvent; + type MaxDrivesPerUser = ConstU32<100>; // Max drives per account + type MaxDriveNameLength = ConstU32<256>; // Max name length +} +``` + +#### 2. Deploy Pallet + +Ensure the Drive Registry pallet is included in the runtime: + +```rust +construct_runtime!( + pub enum Runtime { + System: frame_system, + Balances: pallet_balances, + StorageProvider: pallet_storage_provider, // Layer 0 + DriveRegistry: pallet_drive_registry, // Layer 1 + // ... other pallets + } +); +``` + +#### 3. Verify Genesis State + +Check genesis configuration: + +```bash +# Verify pallet is initialized +polkadot-js-apps -> Developer -> Chain State -> driveRegistry +``` + +--- + +## Provider Management + +### Register a Storage Provider + +Storage providers must be registered in Layer 0 before they can accept drive agreements: + +```rust +// Via Layer 0 pallet +use pallet_storage_provider::Call as StorageProviderCall; + +// 1.

You specify what you need (size, duration, budget), and the system sets up everything automatically. + +### Basic Drive Creation + +```rust +use file_system_primitives::CommitStrategy; + +// Create a 10 GB drive for 500 blocks +let drive_id = fs_client.create_drive( + Some("My Documents"), // Drive name (optional) + 10_000_000_000, // 10 GB capacity + 500, // 500 blocks duration + 1_000_000_000_000, // 1 token payment (12 decimals) + None, // Auto-select providers + None, // Use default commit strategy +).await?; + +println!("✅ Drive created with ID: {}", drive_id); +``` + +**What happens automatically:** +1. System creates a bucket in Layer 0 +2. Selects 1 provider (short-term storage) +3. Requests storage agreement with provider +4. Sets up empty drive structure +5. Configures batched commits (every 100 blocks) + +### Understanding the Parameters + +| Parameter | Type | Description | Example | +|-----------|------|-------------|---------| +| `name` | `Option<&str>` | Human-readable drive name | `Some("My Documents")` | +| `max_capacity` | `u64` | Maximum storage in bytes | `10_000_000_000` (10 GB) | +| `storage_period` | `u64` | Duration in blocks | `500` (≈50 minutes at 6s/block) | +| `payment` | `u128` | Total payment (12 decimals) | `1_000_000_000_000` (1 token) | +| `min_providers` | `Option` | Number of providers | `None` (auto), `Some(3)` | +| `commit_strategy` | `Option` | Checkpoint frequency | `None` (default), `Some(...)` | + +### Storage Duration Examples + +```rust +// Short-term (1 hour at 6s/block) +let storage_period = 600; + +// Medium-term (1 day) +let storage_period = 14_400; + +// Long-term (1 week) +let storage_period = 100_800; + +// Very long-term (1 month) +let storage_period = 432_000; +``` + +--- + +## File Operations + +### Upload a File + +```rust +// Read file from disk +let file_data = std::fs::read("./documents/report.pdf")?; + +// Upload to drive +fs_client.upload_file( + drive_id, + "/report.pdf", // Path in drive + &file_data, + bucket_id, // Associated bucket ID +).await?; + +println!("✅ File uploaded: /report.pdf"); +``` + +**What happens:** +1. File is split into chunks (if large) +2. Chunks are uploaded to provider +3. FileManifest is created with chunk references +4. Parent directory is updated +5. Changes are queued for next checkpoint + +### Upload to Subdirectory + +```rust +// Auto-creates parent directories +fs_client.upload_file( + drive_id, + "/documents/work/report.pdf", + &file_data, + bucket_id, +).await?; + +// Creates: /documents/ and /documents/work/ automatically +``` + +### Download a File + +```rust +let file_data = fs_client.download_file( + drive_id, + "/report.pdf", +).await?; + +// Save to local disk +std::fs::write("./downloaded_report.pdf", file_data)?; + +println!("✅ File downloaded: report.pdf"); +``` + +### Delete a File + +```rust +fs_client.delete_file( + drive_id, + "/old_document.pdf", + bucket_id, +).await?; + +println!("✅ File deleted: /old_document.pdf"); +``` + +**Note:** Deletion updates the directory structure but doesn't immediately remove the data from storage (chunks remain until garbage collected). + +--- + +## Directory Operations + +### Create a Directory + +```rust +fs_client.create_directory( + drive_id, + "/documents", + bucket_id, +).await?; + +println!("✅ Directory created: /documents"); +``` + +### Create Nested Directories + +```rust +// Creates all parent directories automatically +fs_client.create_directory( + drive_id, + "/work/projects/2024/q1", + bucket_id, +).await?; +``` + +### List Directory Contents + +```rust +let entries = fs_client.list_directory( + drive_id, + "/documents", +).await?; + +println!("Contents of /documents:"); +for entry in entries { + let type_str = if entry.is_directory { "DIR" } else { "FILE" };

+ +println!("✅ Drive renamed"); +``` + +### Delete a Drive + +```rust +// Must be the drive owner +delete_drive(drive_id).await?; + +println!("✅ Drive deleted"); +``` + +**Requirements:** +- You must be the drive owner +- Best practice: Delete all files first (cleanup) + +### Check Drive Status + +```rust +let drive_info = get_drive_info(drive_id).await?; + +println!("Drive Status:"); +println!(" Owner: {:?}", drive_info.owner); +println!(" Bucket: {}", drive_info.bucket_id); +println!(" Root CID: 0x{}", hex::encode(drive_info.root_cid)); +println!(" Capacity: {} / {} bytes", current_usage, drive_info.max_capacity);

+``` + +**Use case:** Company records, legal documents, irreplaceable data + +### Real-Time Collaboration + +For shared drives where changes need immediate visibility: + +```rust +let drive_id = fs_client.create_drive( + Some("Team Project"), + 10_000_000_000, // 10 GB + 1_000, // 1000 blocks + 3_000_000_000_000, // 3 tokens (immediate commits = more transactions) + Some(3), // 3 providers (standard redundancy) + Some(CommitStrategy::Immediate), // Every change commits immediately +).await?; +``` + +**Use case:** Shared documents, real-time collaboration, live data + +### Manual Checkpoint Control + +For batch operations where you want to control checkpoints: + +```rust +let drive_id = fs_client.create_drive( + Some("Batch Upload"), + 50_000_000_000, // 50 GB + 500, // 500 blocks + 5_000_000_000_000, // 5 tokens + Some(3), // 3 providers + Some(CommitStrategy::Manual), // User controls commits +).await?;

+``` + +--- + +## Best Practices + +### Storage Planning + +1. **Estimate Your Needs** + ```rust + // Calculate required capacity + let total_files_size = 8_500_000_000; // 8.5 GB + let buffer = 1.2; // 20% buffer for metadata + let max_capacity = (total_files_size as f64 * buffer) as u64; // ~10 GB + ``` + +2. **Choose Appropriate Duration** + - Short-term (<1000 blocks): Temporary files, caches + - Medium-term (1000-10000 blocks): Active projects + - Long-term (>10000 blocks): Archives, backups + +3. **Calculate Payment** + ```rust + // Check provider price first + let price_per_byte = 1_000_000;

"DriveNotFound" Error + +**Problem:** Trying to access non-existent drive + +**Solutions:** +- Verify drive_id is correct +- Check if drive was deleted +- Ensure you're querying the right network + +#### 4. "NotDriveOwner" Error + +**Problem:** Trying to modify someone else's drive + +**Solution:** +- Verify you're using the correct account +- Check drive ownership: `get_drive_info(drive_id).owner` + +#### 5. Upload Fails + +**Problem:** File upload fails silently + +**Checklist:** +```rust +// 1. Verify drive exists +let drive_info = get_drive_info(drive_id).await?; + +// 2. Check bucket is valid +let bucket_info = get_bucket_info(drive_info.bucket_id).await?; + +// 3. Verify provider is active +let provider_info = get_provider_info(provider_id).await?; + +// 4.

Upload File + +**Client SDK:** +```rust +// Simple file upload +fs_client.upload_file( + drive_id, + "/documents/report.pdf", + file_bytes, +).await? +``` + +**What happens under the hood:** +1. Client splits file into chunks +2. Uploads chunks to pool's bucket (transparent) +3. Creates FileManifest +4. Updates directory structure +5. Calculates new root CID +6. Stores as `pending_root_cid` (not yet on-chain) +7. **If pool uses batched commits**: Waits for interval +8. **If pool uses immediate commits**: Commits right away + +**Cost:** +- File upload: Layer 0 storage cost (paid to providers) +- Commit (batched): 1 transaction per 100 files +- Commit (immediate): 1 transaction per file + +#### 4. Create Folder + +**Client SDK:** +```rust +fs_client.create_directory( + drive_id, + "/images", +).await? +``` + +**What happens:** +1. Creates new empty DirectoryNode +2. Uploads to pool's bucket +3. Updates parent directory +4. Updates pending_root_cid + +#### 5. List Directory + +**Client SDK:** +```rust +let entries = fs_client.list_directory(drive_id, "/documents").await?; + +for entry in entries { + println!("{} ({} bytes)", entry.name, entry.size); +} +``` + +**Output:** +``` +report.pdf (1048576 bytes) +presentation.pptx (2097152 bytes) +notes.txt (4096 bytes) +``` + +#### 6. Download File + +**Client SDK:** +```rust +let file_bytes = fs_client.download_file( + drive_id, + "/documents/report.pdf" +).await?; + +std::fs::write("./report.pdf", file_bytes)?; +``` + +**What happens:** +1. Query drive's root CID from chain +2. Traverse DAG to find file +3. Fetch FileManifest +4. Download chunks from pool's bucket +5. Reassemble file + +#### 7. Delete File + +**Client SDK:** +```rust +fs_client.delete_file( + drive_id, + "/documents/old_report.pdf" +).await? +``` + +**What happens:** +1. Removes entry from parent directory +2.

Add cleanup_bucket_internal() for complete bucket cleanup - Ends all agreements with prorated refunds - Pays providers for time served - Removes bucket from storage - Emits BucketDeleted event Layer 1 (pallet-drive-registry): - Add clear_drive() extrinsic to wipe drive contents - Resets root CID to zero - Keeps drive structure and agreements intact - No refunds (storage continues) - Update delete_drive() to properly cleanup buckets - Calls cleanup_bucket_internal() in Layer 0 - Provides prorated refunds to drive owner - Removes bucket-to-drive mapping - Emits DriveDeleted event with refund amount Tests: - Add clear_drive tests (ownership, multiple clears) - Update delete_drive tests for new behavior - Add integration test for Layer 0 dependency Documentation: - Update API_REFERENCE.md with clear_drive and updated delete_drive - Add DriveCleared and update DriveDeleted events - Add BucketCleanupFailed error documentation - Update USER_GUIDE.md with clear vs delete comparison Key improvements: - Drive owners now receive refunds when deleting drives - Clear distinction between clearing (wipe) and deleting (remove) -

Changes: - Create SCALE-encoded types (DirectoryEntry, DirectoryNode, FileManifest, FileChunk, EntryType) that work in no_std environments - Make prost/proto module std-only via #[cfg(feature = "std")] - Add conversion traits between SCALE and proto types for std builds - Update file-system-client to use new SCALE types API - Update examples to use new API (name_str(), to_scale_bytes(), etc.) - Make prost, prost-types, thiserror optional dependencies This fixes the "duplicate lang item in crate core" error that occurred when building the runtime with Rust 1.88.0. --- .../client/examples/basic_usage.rs | 6 +- .../file-system/client/src/lib.rs | 129 ++- .../file-system/examples/basic_usage.rs | 154 ++-- .../examples/pallet_interaction.rs | 7 +- .../file-system/primitives/Cargo.toml | 17 +- .../file-system/primitives/src/lib.rs | 789 ++++++++++++++---- 6 files changed, 754 insertions(+), 348 deletions(-) diff --git a/storage-interfaces/file-system/client/examples/basic_usage.rs b/storage-interfaces/file-system/client/examples/basic_usage.rs index 57ea60e..152bbc1 100644 --- a/storage-interfaces/file-system/client/examples/basic_usage.rs +++ b/storage-interfaces/file-system/client/examples/basic_usage.rs @@ -114,7 +114,7 @@ async fn main() -> Result<(), Box> { let root_entries = fs_client.list_directory(drive_id, "/").await?;

Rust toolchain, system dependencies, rust cache, and free disk space were only needed for the build step which has been removed. * ci: restore free disk space step in setup job * fix: use host function signing in benchmarks for no_std compatibility Pair::sign is unavailable in no_std (requires randomness). Switch to sp_io::crypto::sr25519_generate and sr25519_sign host functions, and register a MemoryKeystore in test externalities to support them. * chore: use pre-built binary for provider node in justfile The build dependency already ensures the binary exists, so skip the redundant cargo invocation. * feat: add genesis bucket creation for storage provider pallet Pre-create two buckets (bucket_id=0 and bucket_id=1) with Bob as admin at genesis, improving developer experience by having ready-to-use buckets on chain start. Also adds formatting section to CLAUDE.md, fixes zepter feature propagation for sp-keystore, and tweaks zombienet log levels. * refactor: move demo binaries from client to separate examples crate Separates the 5 demo/tool binaries (demo_setup, demo_upload, demo_checkpoint, demo_challenge, challenge_watcher) into a dedicated storage-examples crate so the client crate is purely a library. The justfile now prebuilds via build-examples and runs binaries directly, avoiding redundant cargo run recompilation checks. * chore: simplify justfile downloads and merge integration CI into single job Collapse ~100 lines of copy-paste download recipes into a reusable _download helper with computed URL variables. Mark internal recipes (downloads, check, build-examples) as [private] to declutter just --list. Merge the two-job integration CI (setup + integration-tests) into a single job to avoid redundant checkouts and cache restores. * test: assert two ChallengeDefended events in demo workflow Capture challenge watcher output and verify exactly two challenges were defended (off-chain and on-chain checkpoint). The demo now fails if the watcher does not successfully respond to both challenges. --------- Co-authored-by: Naren Mudigal --- .github/workflows/integration-tests.yml | 55 +---- CLAUDE.md | 19 +- Cargo.lock | 21 +- Cargo.toml | 3 + client/Cargo.toml | 17 -- examples/Cargo.toml | 44 ++++ .../src/bin/challenge_watcher.rs | 0 .../src/bin/demo_challenge.rs | 0 .../src/bin/demo_checkpoint.rs | 0 {client => examples}/src/bin/demo_setup.rs | 0 {client => examples}/src/bin/demo_upload.rs | 0 justfile | 190 +++++++----------- pallet/Cargo.toml | 2 + pallet/src/benchmarking.rs | 172 +++++++++++++--- pallet/src/lib.rs | 22 ++ pallet/src/mock.rs | 6 +- runtime/src/genesis_config_presets.rs | 14 ++ runtime/src/lib.rs | 4 +- scripts/build-chain-spec.sh | 2 +- zombienet.toml | 4 +- 20 files changed, 343 insertions(+), 232 deletions(-) create mode 100644 examples/Cargo.toml rename {client => examples}/src/bin/challenge_watcher.rs (100%) rename {client => examples}/src/bin/demo_challenge.rs (100%) rename {client => examples}/src/bin/demo_checkpoint.rs (100%) rename {client => examples}/src/bin/demo_setup.rs (100%) rename {client => examples}/src/bin/demo_upload.rs (100%) diff --git a/.github/workflows/integration-tests.yml b/.github/workflows/integration-tests.yml index 51e0afd..62bbb64 100644 --- a/.github/workflows/integration-tests.yml +++ b/.github/workflows/integration-tests.yml @@ -12,8 +12,8 @@ concurrency: cancel-in-progress: true jobs: -

The new demo.mjs script: - Connects to chain via PAPI with native event subscription - Performs setup, upload, 2 challenges + 2 responses synchronously - Asserts exactly 2 ChallengeDefended events - No background processes, no sleep-based synchronization, no log grep The old bash demo is preserved as `just demo-legacy`. CI updated: added Node.js setup and PAPI descriptor generation step. * ci: run both legacy and PAPI demos in integration tests * fix: replace fixed sleep with polling loop for challenge defense assertion The 30s sleep was not always enough for the watcher to respond to the second challenge in CI. Now polls the watcher log every 2s for up to 120s, proceeding as soon as both challenges are defended. * refactor: rename demo.mjs to demo.js, add error handling and upload assertion - Rename to .js since package.json already has "type": "module" - Add catch block with error logging and non-zero exit code - Assert uploaded data matches by downloading it back from provider * refactor: extract demo steps into named functions for readability Break the monolithic main() into registerProvider, createBucket, createAgreement, uploadData, challengeOffchain, submitCheckpoint, challengeCheckpoint, and respondToChallenge. Remove unused ALICE_SS58 constant and waitFor helper. * refactor: remove storage-examples crate and demo-legacy The PAPI-based demo (`just demo`) fully replaces the Rust binary orchestration. Remove the storage-examples crate (demo_setup, demo_upload, demo_challenge, demo_checkpoint, challenge_watcher) and all associated justfile recipes (demo-legacy, demo-setup, demo-upload, demo-challenge, start-watcher, build-examples). * rename demo.js to full-flow.js * chore: remove redundant examples/papi/.gitignore Already covered by node_modules/ in root .gitignore. --------- --- .github/workflows/integration-tests.yml | 8 + .gitignore | 3 + Cargo.lock | 19 - Cargo.toml | 2 - examples/Cargo.toml | 44 --- examples/papi/full-flow.js | 363 ++++++++++++++++++ examples/papi/package.json | 20 + examples/src/bin/challenge_watcher.rs | 474 ------------------------ examples/src/bin/demo_challenge.rs | 144 ------- examples/src/bin/demo_checkpoint.rs | 91 ----- examples/src/bin/demo_setup.rs | 184 --------- examples/src/bin/demo_upload.rs | 122 ------ justfile | 126 +------ 13 files changed, 404 insertions(+), 1196 deletions(-) delete mode 100644 examples/Cargo.toml create mode 100644 examples/papi/full-flow.js create mode 100644 examples/papi/package.json delete mode 100644 examples/src/bin/challenge_watcher.rs delete mode 100644 examples/src/bin/demo_challenge.rs delete mode 100644 examples/src/bin/demo_checkpoint.rs delete mode 100644 examples/src/bin/demo_setup.rs delete mode 100644 examples/src/bin/demo_upload.rs diff --git a/.github/workflows/integration-tests.yml b/.github/workflows/integration-tests.yml index 62bbb64..6fc6d57 100644 --- a/.github/workflows/integration-tests.yml +++ b/.github/workflows/integration-tests.yml @@ -39,6 +39,11 @@ jobs: sudo apt-get update sudo apt-get install -y protobuf-compiler libclang-dev jq + - name: Setup Node.js + uses: actions/setup-node@v4 + with: + node-version: "22" + - name: Rust cache uses: Swatinem/rust-cache@v2 with: @@ -102,6 +107,9 @@ jobs: sleep 2 done + - name: Generate PAPI descriptors + run: just papi-setup + - name: Run demo run: just demo diff --git a/.gitignore b/.gitignore index 2e20d6b..ec29662 100644 --- a/.gitignore +++ b/.gitignore @@ -23,3 +23,6 @@ Thumbs.db # Downloaded binaries .bin/ + +# Node.js +node_modules/ diff --git a/Cargo.lock b/Cargo.lock index e94565a..0e74a10 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -7090,25 +7090,6 @@ dependencies = [ "tracing-subscriber", ] -[[package]] -name = "storage-examples" -version = "0.1.0" -dependencies = [ - "base64 0.22.1", - "hex", - "reqwest", - "scale-value", - "serde", - "serde_json", - "sp-core", - "sp-runtime", - "storage-client", - "storage-primitives", - "subxt", - "subxt-signer", - "tokio", -] - [[package]] name = "storage-parachain-runtime" version = "0.1.0" diff --git a/Cargo.toml b/Cargo.toml index 7e91ada..61124bf 100644 --- a/Cargo.toml +++ b/Cargo.toml @@ -2,7 +2,6 @@ resolver = "2" members = [ "client", - "examples", "pallet", "primitives", "provider-node", @@ -19,7 +18,6 @@ repository = "https://github.com/parity/scalable-web3-storage" # Internal crates pallet-storage-provider = { path = "pallet", default-features = false } storage-client = { path = "client" } -storage-examples = { path = "examples" } storage-parachain-runtime = { path = "runtime" } storage-primitives = { path = "primitives", default-features = false } storage-provider-node = { path = "provider-node" } diff --git a/examples/Cargo.toml b/examples/Cargo.toml deleted file mode 100644 index 3711d23..0000000 --- a/examples/Cargo.toml +++ /dev/null @@ -1,44 +0,0 @@ -[package] -name = "storage-examples" -version = "0.1.0" -authors.workspace = true -edition.workspace = true -license.workspace = true -repository.workspace = true -description = "Demo binaries and tools for scalable Web3 storage" -publish = false - -[dependencies] -storage-client = { workspace = true } -storage-primitives = { workspace = true, features = ["serde", "std"] } -sp-core = { workspace = true, features = ["std"] } -sp-runtime = { workspace = true, features = ["std"] } -tokio = { workspace = true } -serde = { workspace = true, features = ["std"] } -serde_json = { workspace = true } -hex = "0.4" -base64 = "0.22" -reqwest = { workspace = true } -scale-value = "0.16" -subxt = "0.37" -subxt-signer = { version = "0.37", features = ["sr25519"] } - -[[bin]] -name = "demo_setup" -path = "src/bin/demo_setup.rs" - -[[bin]] -name = "demo_upload" -path = "src/bin/demo_upload.rs" - -[[bin]] -name = "demo_checkpoint" -path = "src/bin/demo_checkpoint.rs" - -[[bin]] -name = "demo_challenge" -path = "src/bin/demo_challenge.rs" - -[[bin]] -name = "challenge_watcher" -path = "src/bin/challenge_watcher.rs" diff --git a/examples/papi/full-flow.js b/examples/papi/full-flow.js new file mode 100644 index 0000000..2d84ae0 --- /dev/null +++ b/examples/papi/full-flow.js @@ -0,0 +1,363 @@ +/** + * PAPI-based integration test for web3-storage. + * + * Replaces the bash demo orchestration with a single script that: + * 1.

The new demo.mjs script: - Connects to chain via PAPI with native event subscription - Performs setup, upload, 2 challenges + 2 responses synchronously - Asserts exactly 2 ChallengeDefended events - No background processes, no sleep-based synchronization, no log grep The old bash demo is preserved as `just demo-legacy`. CI updated: added Node.js setup and PAPI descriptor generation step. * ci: run both legacy and PAPI demos in integration tests * fix: replace fixed sleep with polling loop for challenge defense assertion The 30s sleep was not always enough for the watcher to respond to the second challenge in CI. Now polls the watcher log every 2s for up to 120s, proceeding as soon as both challenges are defended. * refactor: rename demo.mjs to demo.js, add error handling and upload assertion - Rename to .js since package.json already has "type": "module" - Add catch block with error logging and non-zero exit code - Assert uploaded data matches by downloading it back from provider * refactor: extract demo steps into named functions for readability Break the monolithic main() into registerProvider, createBucket, createAgreement, uploadData, challengeOffchain, submitCheckpoint, challengeCheckpoint, and respondToChallenge. Remove unused ALICE_SS58 constant and waitFor helper. * refactor: remove storage-examples crate and demo-legacy The PAPI-based demo (`just demo`) fully replaces the Rust binary orchestration. Remove the storage-examples crate (demo_setup, demo_upload, demo_challenge, demo_checkpoint, challenge_watcher) and all associated justfile recipes (demo-legacy, demo-setup, demo-upload, demo-challenge, start-watcher, build-examples). * rename demo.js to full-flow.js * chore: remove redundant examples/papi/.gitignore Already covered by node_modules/ in root .gitignore. * fix: reorder PORT as first parameter in start-provider recipe just uses positional parameters, so PORT must come first to allow `just start-provider 3001` without passing SEED and CHAIN_WS. * fix: use top-level variable for PORT in start-provider just supports KEY=VALUE overrides for top-level variables, not recipe parameters. Usage: just PORT=3001 start-provider * chore: make demo depend on papi-setup Removes the need to run papi-setup separately. Also removes the now-redundant CI step. * chore: ignore generated .papi/ and package-lock.json * Logs * ci: remove redundant papi-setup step Already runs as a dependency of `just demo`. --------- --- .github/workflows/integration-tests.yml | 4 ---- .gitignore | 2 ++ justfile | 8 ++++++-- 3 files changed, 8 insertions(+), 6 deletions(-) diff --git a/.github/workflows/integration-tests.yml b/.github/workflows/integration-tests.yml index 6fc6d57..20783cd 100644 --- a/.github/workflows/integration-tests.yml +++ b/.github/workflows/integration-tests.yml @@ -107,9 +107,6 @@ jobs: sleep 2 done - - name: Generate PAPI descriptors - run: just papi-setup - - name: Run demo run: just demo @@ -121,7 +118,6 @@ jobs: pkill -f "storage-provider-node" 2>/dev/null || true - name: Upload logs (on failure) - if: failure() uses: actions/upload-artifact@v4 with: name: integration-test-logs diff --git a/.gitignore b/.gitignore index ec29662..860c03c 100644 --- a/.gitignore +++ b/.gitignore @@ -26,3 +26,5 @@ Thumbs.db # Node.js node_modules/ +package-lock.json +.papi/ diff --git a/justfile b/justfile index 083b5ab..4270c58 100644 --- a/justfile +++ b/justfile @@ -17,6 +17,9 @@ polkadot_sdk_base := "https://github.com/paritytech/polkadot-sdk/releases/downlo darwin_suffix := if os == "darwin" { "-aarch64-apple-darwin" } else { "" } zombienet_asset := if os == "darwin" { if arch == "arm64" { "zombienet-macos-arm64" } else { "zombienet-macos-x64" } } else { "zombienet-linux-x64" } +# Provider port (override with: just PORT=3001 start-provider) +PORT := "3000" + # Default recipe default: @just --list @@ -80,10 +83,11 @@ start-provider SEED="//Alice" CHAIN_WS="ws://127.0.0.1:9944": build echo "" echo "=== Starting Storage Provider Node ===" echo "" - echo "Provider health: http://127.0.0.1:3000/health" + echo "Provider health: http://127.0.0.1:{{ PORT }}/health" echo "" SEED="{{SEED}}" \ CHAIN_RPC="{{CHAIN_WS}}" \ + BIND_ADDR="0.0.0.0:{{ PORT }}" \ ./target/release/storage-provider-node # Health check for provider node @@ -97,7 +101,7 @@ stats: # Demo: full integration test (PAPI-based) # Runs setup, upload, 2 challenges + responses, and asserts 2 ChallengeDefended events. # Requires: npm install in examples/papi/ and descriptors generated (just papi-setup). -demo CHAIN_WS="ws://127.0.0.1:9944" PROVIDER_URL="http://127.0.0.1:3000": +demo CHAIN_WS="ws://127.0.0.1:9944" PROVIDER_URL="http://127.0.0.1:3000": papi-setup node examples/papi/full-flow.js "{{CHAIN_WS}}" "{{PROVIDER_URL}}" # Install PAPI dependencies and generate chain descriptors (requires running chain) From 8c4444b7bbaa2dc9eca6ba90cd487b2fc4916925 Mon Sep 17 00:00:00 2001 From: Naren Mudigal Date: Fri, 20 Feb 2026 23:26:06 +0100 Subject: [PATCH 37/48] feat: add create_bucket_with_storage with automatic provider matching (#12) Adds a new extrinsic that allows users to create buckets with storage requirements and have the system automatically match them to a suitable provider. This eliminates the manual request/accept dance for agreements. Key changes: - New extrinsic `create_bucket_with_storage(max_bytes, duration, max_price_per_byte)` with call_index 16 - Automatic provider selection based on: accepting_primary status, capacity, price, duration constraints, and stake requirements - Selects cheapest matching provider when multiple qualify - Creates bucket and agreement atomically in one transaction - Added NoMatchingProvider error when no suitable provider exists - Added comprehensive tests (7 new tests covering success and error cases) - Added benchmark for the new extrinsic The matching algorithm bridges the gap between users (who work at bucket level with small requests) and providers (who offer capacity pools).

From: Naren Mudigal Date: Thu, 26 Feb 2026 13:23:48 +0100 Subject: [PATCH 39/48] feat: add S3-compatible storage interface (Layer 1) Implement S3-compatible storage interface that provides familiar S3 API semantics on top of Layer 0 blob storage. The S3 pallet internally creates Layer 0 buckets, encapsulating the storage layer from clients. Components: - s3-primitives: Core types (ObjectMetadata, S3BucketInfo) and validation - pallet-s3-registry: On-chain S3 bucket/object metadata with automatic Layer 0 bucket creation via create_bucket_internal() - s3-client: High-level SDK using subxt 0.44 for chain operations and storage-client for provider blob operations Key features: - Bucket operations: create, delete, head, list - Object operations: put, get, delete, copy, list with prefix/delimiter - S3 naming rules validation (3-63 chars, lowercase alphanumeric + hyphens) - Content-addressed storage via CID (blake2-256) - User-defined metadata support The architecture ensures clients only interact with the S3 layer while Layer 0 provides the underlying storage guarantees (checkpoints, challenges, slashing). ---

Client tries to download data, provider fails to respond or returns wrong data +2. Client submits challenge on-chain with: + - Bucket/chunk identifier + - Merkle proof from last checkpoint showing provider committed to having this data +3. Provider has a challenge period (e.g., 100 blocks) to respond with valid data +4. If provider fails: stake is slashed, client receives compensation +5.

This version mismatch caused polkadot-omni-node to fail executing the runtime WASM in CI, while working locally due to cached binaries. Changes: - Update all SDK references to polkadot-stable2512-2 (00fbc91) - Fix generate_session_keys API change (signature changed in new SDK) - Add node_spawn_timeout = 240 to zombienet.toml for
