METHOD AND SYSTEM FOR A TRUSTED EXECUTION ENVIRONMENT-BASED PROOF OF STAKE PROTOCOL

摘要

A method prevents posterior-corruption long-range attacks in a proof of stake blockchain protocol in a blockchain network. The method includes: generating, by a blockchain node associated with a TEE device, a signing key pair, including a public key and a private key; remotely-attesting, by the blockchain node, a trusted enclave application, including generating an attestation certificate; and issuing, by the blockchain node, a registration transaction to distribute the attestation certificate; the registration transaction specifying an amount of mining stake purchased by the blockchain validator. Once the registration transaction is confirmed, the TEE device becomes enabled for mining blocks in the blockchain network.
