Hydra v2.0.5 — Vesting Status Command

🆕 What's New

• 📊 Added: New read-only hydragon vesting-status command that lets validators check their vesting position status on-chain
• 🔍 Queries: 4 view functions across HydraStaking and HydraDelegation contracts — no state changes, no gas costs
• 📋 Displays: Vesting period (in weeks), start/end timestamps, base stake, bonuses, generated rewards, unclaimed rewards, and claimable commissions

📌 Usage

# Human-readable output
hydra hydragon vesting-status --data-dir /path/to/data --jsonrpc http://localhost:8545

# JSON output
hydra hydragon vesting-status --data-dir /path/to/data --jsonrpc http://localhost:8545 --json

📌 Important Notes

• 🧩 This is a read-only command — it only queries on-chain state, no transactions are sent.
• ⛔ Validators with an active vesting position will see full details; validators without vesting will see a compact view with generated rewards, unclaimed rewards, and claimable commissions.

What's Changed

• Add vesting-status CLI command for validators by @ipetrov22 in #131

v2.0.4

Hydra v2.0.4 — Bootnodes and Restart Bootstrap Enhancements

🌐 Mainnet Release

This release brings the bootnode discovery and restart bootstrap improvements previously tested on Testnet to the Mainnet network.

🆕 What's New

• 🗺️ Automatic Bootnode Initialization:
  On first startup, the node automatically generates a bootnodes.json, pre-seeded with the default bootnodes from genesis.json.

• 🔄 Persistent Peer Tracking:
  The node now maintains a last_peers.json file, continuously recording recently connected peers during runtime to speed up reconnections.

• ⚙️ Enhanced Restart Bootstrap:
  On restart, the node first connects to the default bootnodes and then gracefully falls back to peers listed in last_peers.json if needed.

• 🧭 Improved Network Resilience:
  Optimized peer discovery and recovery flow ensures smoother restarts and faster network convergence without manual peer configuration.

📌 Important Notes

• 🧩 Default bootnodes remain the primary discovery source; last_peers.json serves as a fallback only.
• 🧼 For best performance, perform graceful shutdowns to ensure last_peers.json captures a fresh, valid peer set.
• 💾 Both bootnodes.json and last_peers.json are human-readable JSON lists of multiaddrs for easy inspection and manual edits.
• ⛔ All validators must upgrade to adopt the new bootnode and restart logic.

What's Changed

• Introduce bootnodes discovery feature by @s-h-ubham in #121
• Improve peer persistence and bootnode loading by @s-h-ubham in #128
• persist active-first peers with debounced writer by @s-h-ubham in #129
• Resolves bootnodes loading issues by @s-h-ubham in #130

Hydra v2.0.4-rc — Bootnodes and Restart Bootstrap Enhancements(Testnet Release)

Hydra v2.0.4-rc — Bootnodes and Restart Bootstrap Enhancements

🚀 Testnet Release Only

This is a Testnet-only release.

🆕 What's New

• 🗺️ Added: Automatic generation of bootnodes.json on first startup, seeded with default bootnodes from genesis.json.
• 🔄 Introduced: Continuous peer tracking via last_peers.json — the server now records recently connected peers during runtime for faster reconnection.
• ⚙️ Enhanced: Smart restart flow with prioritized fallback — the node first attempts to connect to default bootnodes, then gracefully falls back to peers in last_peers.json if needed.
• 🧭 Improved: Network recovery and bootstrap performance, ensuring smoother restarts without manual peer configuration.

📌 Important Notes

• 🧩 Default bootnodes remain the primary source for discovery; last_peers.json acts only as a fallback.
• 🧼 Prefer graceful shutdowns so that last_peers.json captures an up-to-date, high-quality peer list.
• 💾 Both bootnodes.json and last_peers.json are simple JSON lists of multiaddrs for easy inspection and editing.
• ⛔ All validators must upgrade to adopt the new logic.

Hydra v2.0.0

Breaking Changes – Action Required

This release introduces the Price Oracle Fix, which will be activated at block 12419989 (approximately 20 days after this release). Node operators must upgrade to ensure accurate price fetching and maintain consensus.

Additionally, the --chain flag for the server command has been simplified to accept predefined network values instead of requiring a genesis file path.

⚠️ Upgrade Instructions

• Validators & Node Operators: Upgrade before block 12419989 to ensure proper price oracle functionality.
• --chain flag of the server command doesn't need a genesis path anymore but instead uses mainnet or testnet as values. More information can be found in the README.md file.

What's Changed

• Fix readme by @R-Santev in #95
• 349 add multi network genesis configuration by @R-Santev in #107
• Introduce price oracle fix by @R-Santev in #108

Hydra v1.0.0: Foundations for the Future

Today, we release Hydra v1.0.0 — the first chapter of an ambitious story. Built for speed, scalability, and resilience, Hydra introduces sub-1-second block times, instant finality, and the promise of seamless cross-shard communication through Project Prometheus. Early stress tests have shown its capabilities, but we know this is only the foundation for what’s to come.

This is not just a release; it’s an invitation to developers, innovators, and dreamers to explore what’s possible. Together, we’ll shape the next evolution of decentralized technology, one block at a time.
