BTOOLS: Trusted Transaction Generation for Bitcoin and Ethereum Blockchain Based on Crypto Currency SmartCard

摘要

This paper presents an innovative and open software framework whose goal is to increase the trust of blockchain transactions. Transactions are signed by the Elliptic Curve Digital Signature Algorithm (ECDSA) associated with a 32 bytes secret private key. We designed a Javacard application used for key generation, storage and cryptographic procedure dealing with the secp256kl elliptic curve. Our open software BTOOLS generates Bitcoin and Ethereum transactions whose trust is enforced by the support of a Crypto Currency SmartCard (CCSC).
