Abstract

A method for signing a new block of a blockchain of a distributed blockchain consensus network (DBCN), comprising a mining computing entity (MCE) and a node computing entity, includes the step of signing and/or encrypting of predefined MCE information by the MCE, using a secret key of a public key/secret key key pair of the MCE to obtain hidden information (HI). The new block is signed by the MCE using the secret key and block information comprising block height information to create a signature for the new block. In a case of at least one further signing of a different block with the respective same block height information by the MCE, reveal information is provided to reveal the HI to the DBCN by another node computing entity of the DBCN when the node computing entity has received two signatures comprising the same corresponding block height information.
