No Repudiation in Distributed Ledgers: P-256 ECDSA Digital Signatures
Los secretos compartidos son un antipatrón en sistemas de ledger distribuido. wFabricSecurity impone criptografía de clave pública con ECDSA P-256 para un no repudio total.

wFabricSecurity, an open-source project by Wisrovi, has introduced a solution to address shared secrets vulnerabilities in distributed ledger systems. The project utilizes public key cryptography with ECDSA P-256 to ensure non-repudiation. On the second day of its technical series, wFabricSecurity presented its implementation, which includes a Python library that enables nodes to sign and verify JSON payloads.
The solution has been tested and verified in Hyperledger Fabric environments and is compatible with Python 3.10+. The project is available on GitHub and PyPI.
