  • Patent number: 11082291
    Abstract: Operating conditions of a blockchain configuration may be dynamic and change automatically under certain circumstances. One example method of operation may include one or more of identifying an existing consensus procedure used in an existing blockchain configuration, identifying current metrics associated with the existing blockchain configuration, comparing the current metrics to predefined rules, identifying one or more deviations based on the current metrics being compared to the predefined rules, and changing the existing consensus procedure to a next consensus procedure for a subsequent block in the existing blockchain configuration responsive to identifying the one or more deviations.

  • Patent number: 10360191
    Abstract: The system, method, and computer program product described herein provides a built-in feedback mechanism for a blockchain to sanction validator nodes that consistently “vote” in a manner that does not match the ultimate consensus. The method includes receiving a vote on whether to add a transaction to the blockchain, comparing the vote to a consensus decision on whether to add the transaction to the blockchain, determining based on the comparison that the vote does not match the consensus decision, in response to determining that the vote does not match the consensus decision, incrementing a value associated with the validator node in a feedback registry, determining that the value associated with the validator node is above a predetermined threshold value, and in response to determining that the value associated with the validator node is above the predetermined threshold, proposing a sanction of the validator node to the plurality of validator nodes.

  • Publication number: 20180096360
    Abstract: The present disclosure relates to the enforcement of a smart contract execution hierarchy on a blockchain. A method includes receiving a submission of a first smart contract to be appended to a blockchain, comparing a priority value of the first smart contract to a priority value of a second smart contract previously appended to the blockchain, determining based on the comparison that the first smart contract has a lower priority than the second smart contract, comparing the terms of the first smart contract to the terms of the second smart contract, determining at least one of an overlap and a conflict between the terms of the first smart contract and the terms of the second smart contract, resolving any terms of the first smart contract that are determined to overlap or conflict with the terms of the second smart contract, and appending the resolved first smart contract to the blockchain.
