Unreleased

0.2.4 - 2025-03-12

Fixed

• Remove corrupted test_slush.rs:: files from git

0.2.2 - 2025-03-12

Added

• Slush protocol example from Avalanche paper (Section 2.2) as ApplicationObject
• examples/slush_example.rs: 10-node metastable consensus demo over real UDP
• tests/test_slush.rs: 13 tests (unit + integration)

Changed

• Package and crate renamed from chaincraft-rust to chaincraft (crates.io/docs.rs)
• GitHub repository remains chaincraft-rust

0.2.1 - 2025-03-10

Fixed

• VDF tests for CI (--all-features): iteration minimum 66, conditional test for feature-off case
• CI: install libgmp-dev for vdf-crypto feature

0.2.0 - 2025-03-05

Added

• ECDSA-based VRF primitive (matches Python crypto_primitives/vrf.py)
• Symmetric encryption (Fernet, Python-compatible) in SymmetricEncryption
• rand_core feature for ed25519-dalek key generation

Changed

• Removed libp2p dependency; all P2P/socket logic is in-house (UDP)
• Updated openssl-tls feature (no longer depends on libp2p)

Removed

• libp2p and libp2p-websocket dependencies

0.1.0 - 2025-06-11

Added

• Initial release of ChainCraft Rust
• Core blockchain data structures and validation
• P2P networking with peer discovery

• Modular consensus framework
• Flexible storage backends (memory, persistent)
• CLI interface for node management
• Comprehensive test suite
• Documentation and examples
• GitHub Actions for CI/CD
• Automated publishing to crates.io

Features

• Node Management: Start, stop, and configure blockchain nodes
• Cryptography: Key generation, signing, and verification
• Networking: P2P communication and peer discovery
• Storage: Multiple storage backend options
• CLI: Command-line interface for easy node operations
• Modularity: Pluggable components for customization

Security

• Memory-safe Rust implementation
• Cryptographic operations using audited libraries
• Input validation throughout the codebase

Performance

• Async networking with tokio
• Efficient serialization with bincode
• Configurable resource limits
• Optimized cryptographic operations
