Abstract
Description
Claims (30)
- A computer-implemented method for managing updates to smart contracts executed in blockchain networks, the method comprising:receiving, by a contract updates management system, an update request indicating a change to a smart contract, the change being a proposed update to the smart contract;determining, by executing an updates smart contract within the contract updates management system, whether conditions are met for updating the smart contract to incorporate the change, the updates smart contract defining the conditions; andupon determining, by the contract updates management system, that the conditions are met, updating, by the contract updates management system, the smart contract, and recording the change to one or more blocks in a blockchain of a blockchain network.
- The method of claim 1, wherein the update request comprises an identifier assigned to the smart contract within the blockchain network.
- The method of claim 1, wherein the update request comprises an identifier assigned to the updates smart contract within the blockchain network.
- The method of claim 1, wherein the smart contract comprises:a controller contract defined by a dispatcher upon receipt of a request by a contract originator who originates the smart contract;a service contract that includes logic of the smart contract; anda data contract that includes terms of the smart contract.
- The method of claim 1, wherein determining whether the conditions are met includes performing a voting process comprising:sending a request to one or more nodes in the blockchain network for a vote relative to the change;collecting votes from the one or more nodes; anddetermining that conditions are met when the collected votes indicate an approval of the change by the one or more nodes.
- The method of claim 5, wherein performing the voting process includes weighting votes by weights associated with respective nodes, and wherein approval is based on a function of the collected votes and their associated weights.
- The method of claim 5, wherein performing the voting process includes applying a veto received from a veto-privileged node, wherein the voting process ends when a veto is received for the change during the voting process, the veto causing the change to be rejected.
