Implementation Details

BIP-341 (Taproot)

Implementation of the Taproot proposal, which introduces a new SegWit version 1 output type that can be spent using either a key path or by satisfying a script path.

Features Implemented: - Taproot Merkle Tree construction - Taproot spend validation - Taproot output generation - Key path spending - Script path spending

Location: core/src/bip/bip341.rs

BIP-342 (Tapscript)

Implementation of the Tapscript, which defines the semantics of the leaf version and the script execution context for spending Taproot outputs along the script path.

Features Implemented: - Leaf version handling - Tapscript execution - Signature validation with specified rules - Size limits and resource constraints

Location: core/src/bip/bip342.rs

Implementation Priorities

The following BIPs are prioritized for upcoming implementation:

  1. BIP-174 (PSBT) - Partially Signed Bitcoin Transactions
  2. BIP-370 (PSBT v2) - Enhanced version of PSBT
  3. BIP-340 (Schnorr Signatures) - Foundational for later enhancements

Compliance Requirements

All BIP implementations must: - Pass the standard Bitcoin test vectors - Follow the hexagonal architecture pattern - Include comprehensive security checks - Be thoroughly documented

Testing Strategy

  1. Unit Tests: Direct validation of implementation against test vectors
  2. Integration Tests: Interaction between multiple BIP implementations
  3. Security Tests: Fuzz testing and edge case exploration
  4. Regression Tests: Ensure compatibility with Bitcoin Core

Audit Status

Regular security audits are conducted on all BIP implementations, with results documented in security/audit/bip_audit_reports.md.
