A method for using a distributed ledger (DL) of a blockchain applicable to a network of blockchain nodes is provided. The method reduces a time period between an assertion placed on the blockchain by an assertor blockchain node and execution of one or more action items dependent on a consensus of the assertion, by: creating an Artificial Intelligence (AI) model, by one of the blockchain nodes of the network, using historical data stored by the DL, wherein the network of blockchain nodes further comprises the assertor blockchain node; calculating an index value indicating a probability that the consensus is true, based on the AI model and the historical data stored by the DL, by the one of the blockchain nodes, wherein each of the blockchain nodes comprises a computer system including at least a processor, a system memory element, and a communication device configured to send and receive data transmissions between the blockchain nodes of the network; and when the index value exceeds a predefined threshold, initiating the execution of the one or more action items dependent on the consensus, by the one of the blockchain nodes.
