Adaptation of Blockchain Consensus Criteria Based on a Computing Context

A method of dynamically adapting a blockchain consensus criteria. The method comprises evaluating a first computing context by a consensus criteria adaptation application executing on a computer, wherein the first context comprises a first current vulnerability to cyber threats and an operational importance of a blockchain, based on evaluating the first computing context, adapting a first blockchain validity consensus criteria by the adaptation application, where the first consensus criteria identifies a first minimum number of consensus voting server computers, a first minimum percentage of approvals among voting server computers, and a first nonce calculation difficulty, applying the first consensus criteria to a first block requested to be added to the first blockchain, and determining, based on applying the first consensus criteria, that the first block is approved to be added to the first blockchain.
