Key summary

VeritasChain Protocol (VCP) has open-sourced its Cloudflare Workers-based implementation of cryptographically verifiable audit trails for algorithmic trading. This solution addresses the fundamental problem of mutable trading system logs by introducing a three-layer architecture that makes tampering mathematically detectable.

TL;DR

  • VCP introduces a three-layer architecture to make tampering mathematically detectable
  • Events are hashed and signed to prevent modification
  • External anchoring is mandatory to prevent system control
  • Cloudflare Workers are used for their latency-sensitive performance
  • VCP defines three compliance tiers and four core event types
  • The implementation is open-source under the MIT License
  • Contributions are welcome through the GitHub repository
  • VCP is being standardized through the IETF as a profile of SCITT
