Abstract

A method for mining a block in a decentralized blockchain consensus network (DBCN) includes sending, by a mining computing entity (MCE), a signing request for mining a new block of a blockchain to a trusted execution environment computing entity (TEE-CE), the signing request including block information, the block information including block height information, and comparing, by the TEE-CE, the block height information of the signing request with block height information from a last signing request and providing a matching, when the difference between the block height information of the signing request and the block height information from the last signing request satisfies a defined value. The method further comprises, upon providing the matching, signing, by the TEE-CE, the new block based on the block information, and providing, by the MCE, the new signed block to the DBCN.
