How to sign new blocks in a decentralized blockchain consensus network

摘要

The present invention relates to a method for signing new blocks in a blockchain of a distributed blockchain consensus network "DBCN" including a mining computing entity "MCE" and a node computing entity. The method comprises the steps of: i. At least one of the following: the MCE signs predetermined MCE information and / or encrypts predetermined MCE information using a secret key of the MCE's public / private key pair. Obtaining confidential information “HI” by performing ii. Creating a signature for the new block by the MCE signing a new block using the secret key and block information including block height information; iii. If the MCE applies at least one more signature to different blocks having the same block height information, the node computing entity may receive another signature including the same corresponding block height information when the node computing entity receives two signatures including the same corresponding block height information. Providing public information to publish the HI to the DBCN. [Selection diagram] Fig. 1
