System and method of decentralized management of multi-owner nodes using blockchain
The disclosure relates to decentralized management of nodes in a blockchain network. Participants may agree to a consensus rules and implement them as smart contracts. For example, one rule may specify that a node will accept a change proposal only when its local policies and/or data allow it to implement the change. A smart contract may implement this rule and deploy it across the blockchain network for each node to follow. Other participants, through their nodes, may propose changes to the blockchain network, and each node may consult its copy of the smart contract to determine whether to vote to approve the change request and apply the change request locally.
1. A decentralized management system for a blockchain network, comprising:
a first node of the blockchain network, wherein the first node includes a processor and instructions programming the processor to cause the first node to:
enroll with the blockchain network to participate in management of the blockchain network;
receive a blockchain transaction with a change request proposed by a second node of the blockchain network;
determine a vote of whether to approve the change request;
transmit the vote to the blockchain network in a blockchain transaction, wherein at least a third node of the blockchain network provides a vote on whether to approve the change request; and
determine that the change request is approved;
implement the change request on the first node; and
generate a blockchain transaction comprising a payload that indicates a state of the first node after implementing the change request.
2. The system of claim 1 , wherein to determine that the change request is approved, the first node is programmed to:
determine a consensus decision that the change request is approved based on the vote and the vote from the third node.
3. The system of claim 1 , wherein to determine that the change request is approved, the first node is programmed to:
read, from a ledger block from a local copy of a distributed ledger of the blockchain network, a consensus decision that the change request is approved.
4. The system of claim 1 , wherein to determine the vote, the first node is programmed to:
obtain a local copy of a smart contract previously agreed to by nodes of the blockchain network.
5. The system of claim 1 , wherein to determine the vote, the first node is programmed to: consult a local policy to determine whether the change request violates the local policy.
6. The system of claim 1 , wherein to transmit the vote, the first node is programmed to transmit the blockchain transaction to at least one other node of the blockchain network.
7. The system of claim 1 , wherein to implement the change request, the first node is programmed to implement the change request in accordance with a smart contract previously agreed to by nodes of the blockchain network.
8. A method of decentralized management of a blockchain network, comprising:
enrolling, by a first node of the blockchain network, with the blockchain network to participate in management of the blockchain network;
receiving, by the first node, a blockchain transaction with a change request proposed by a second node of the blockchain network;
determining, by the first node, a vote of whether to approve the change request;
transmitting, by the first node, the vote to the blockchain network in a blockchain transaction, wherein at least a third node of the blockchain network provides a respective vote on the whether to approve the change request;
determining, by the first node, that the change request is approved;
implementing, by the first node, the change request; and
generating, by the first node, a blockchain transaction comprising a payload that indicates a state of the first node after implementing the change request.
9. The method of claim 8 , wherein determining that the change request is approved comprises:
determining, by the first node, a consensus decision that the change request is approved based on the vote and the respective vote.
10. The method of claim 8 , wherein determining that the change request is approved comprises: reading, by the first node, from a ledger block from a local copy of a distributed ledger of the blockchain network, a consensus decision that the change request is approved.
11. The method of claim 8 , wherein determining the vote comprises: obtaining, by the first node, a local copy of a smart contract previously agreed to by nodes of the blockchain network.
12. The method of claim 8 , wherein determining the vote comprises, consulting, by the first node, a local policy to determine whether the change request violates the local policy.
13. The method of claim 8 , wherein transmitting the vote comprises: transmitting, by the first node, the blockchain transaction to at least one other node of the blockchain network.
14. A non-transitory machine-readable storage medium comprising instructions executable by a processor a first node of a blockchain network, the instructions programming the processor to:
enroll with the blockchain network to participate in management of the blockchain network;
receive a blockchain transaction with a change request proposed by a second node of the blockchain network;
determine a vote of whether to approve the change request;
transmit the vote to the blockchain network in a blockchain transaction, wherein at least a third node of the blockchain network provides a vote on whether to approve the change request; and
determine that the change request is approved;
implement the change request on the first node; and
generate a blockchain transaction comprising a payload that indicates a state of the first node after implementing the change request.
15. The non-transitory machine-readable storage medium of claim 14 , wherein the instructions to determine that the change request is approved comprises instructions to determine a consensus decision that the change request is approved based on the vote and the vote from the third node.
16. The non-transitory machine-readable storage medium of claim 14 , wherein the instructions to determine that the change request is approved comprises instructions to read, from a ledger block from a local copy of a distributed ledger of the blockchain network, a consensus decision that the change request is approved.
17. The non-transitory machine-readable storage medium of claim 14 , wherein the instructions to determine the vote comprises instructions to obtain a local copy of a smart contract previously agreed to by nodes of the blockchain network.
18. The non-transitory machine-readable storage medium of claim 14 , wherein the instructions to determine the vote comprises instructions to consult a local policy to determine whether the change request violates the local policy.
19. The non-transitory machine-readable storage medium of claim 14 , wherein the instructions to transmit the vote comprises instructions to transmit the blockchain transaction to at least one other node of the blockchain network.
20. The non-transitory machine-readable storage medium of claim 14 , wherein the instructions to implement the change request comprise instructions to implement the change request in accordance with a smart contract previously agreed to by nodes of the blockchain network.
