Abstract

Systems and methods for managing blockchain nodes. Blockchain node clusters are created and used to process blockchain requests. Blockchain clusters are managed by adding nodes to a cluster, stopping nodes in the cluster, and generating snapshots of state. of one or more nodes.

First claim

We claim:

1. A system comprising a non-transitory computer readable medium having stored thereon software instructions that, when executed by a processing system, cause the processing system to perform operations comprising:
generating a snapshot of a blockchain chain state of a blockchain node;
identifying a new blockchain node; and
initializing the new blockchain node using the snapshot, wherein a full chain state is initialized for the new blockchain node, wherein the full chain state is determined from the snapshot, an initial snapshot, and a set of intervening snapshots between the initial snapshot and the snapshot.

2. The system of claim 1 , wherein the blockchain chain state captured by the snapshot comprises a change in the blockchain chain state over a prior snapshot.

3. The system of claim 1 , wherein generating the snapshot of the blockchain chain state comprises:
identifying a node configuration to snapshot;
identifying a node agent that manages the blockchain node having the identified node configuration; and
controlling the identified node agent to generate the snapshot of the blockchain chain state of the blockchain node.

4. The system of claim 1 , the operations further comprising verifying blocks in the snapshot based on a blockchain protocol associated with the blockchain chain state.

5. The system of claim 1 , wherein the snapshot comprises an incremental backup of the blockchain chain state over a prior snapshot of the blockchain chain state, and wherein the prior snapshot is generated from a secondary blockchain node, different from the blockchain node.

6. The system of claim 1 , wherein the snapshot is stored in a storage volume, wherein initializing the new blockchain node comprises mounting the storage volume to the new blockchain node.

7. The system of claim 1 , wherein the blockchain node is part of a blockchain node cluster for a blockchain network, wherein the blockchain node is selected for snapshot generation based on a set of health parameters, comprising at least one of a block height, latest block hash, total work on a blockchain synchronized with the blockchain node, or node telemetry.

8. A system comprising a non-transitory computer readable medium having stored thereon software instructions that, when executed by a processing system, cause the processing system to perform operations comprising:
generating a snapshot of a blockchain chain state of a blockchain node synchronized with a blockchain network, wherein generating the snapshot comprises stopping the blockchain node from synchronizing with the blockchain network during snapshot generation;
identifying a new blockchain node; and
initializing the new blockchain node using the snapshot.

9. The system of claim 8 , wherein the blockchain chain state captured by the snapshot comprises a change in the blockchain chain state over a prior snapshot.

10. The system of claim 8 , wherein generating the snapshot of the blockchain chain state comprises:
identifying a node configuration to snapshot;
identifying a node agent that manages the blockchain node having the identified node configuration; and
controlling the identified node agent to generate the snapshot of the blockchain chain state of the blockchain node.

11. The system of claim 8 , the operations further comprising verifying blocks in the snapshot based on a blockchain protocol associated with the blockchain chain state.

12. The system of claim 8 , wherein the snapshot comprises an incremental backup of the blockchain chain state over a prior snapshot of the blockchain chain state, and wherein the prior snapshot is generated from a secondary blockchain node, different from the blockchain node.

13. The system of claim 8 , wherein the blockchain node is part of a blockchain node cluster for the blockchain network, wherein the blockchain node is selected for snapshot generation based on a set of health parameters, comprising at least one of a block height, latest block hash, total work on a blockchain synchronized with the blockchain node, or node telemetry.

14. A system comprising a non-transitory computer readable medium having stored thereon software instructions that, when executed by a processing system, cause the processing system to perform operations comprising:
generating a snapshot of a blockchain chain state of a blockchain node;
identifying a new blockchain node;
initializing the new blockchain node using the snapshot, wherein the blockchain node and the new blockchain node are both part of a blockchain node cluster; and
receiving, from a client, a blockchain transaction and routing the blockchain transaction to at least one blockchain node within the blockchain node cluster.

15. The system of claim 14 , wherein the blockchain chain state captured by the snapshot comprises a change in the blockchain chain state over a prior snapshot.

16. The system of claim 14 , wherein generating the snapshot of the blockchain chain state comprises:
identifying a node configuration to snapshot;
identifying a node agent that manages the blockchain node having the identified node configuration; and
controlling the identified node agent to generate the snapshot of the blockchain chain state of the blockchain node.

17. The system of claim 14 , the operations further comprising verifying blocks in the snapshot based on a blockchain protocol associated with the blockchain chain state.

18. The system of claim 14 , wherein the snapshot comprises an incremental backup of the blockchain chain state over a prior snapshot of the blockchain chain state, and wherein the prior snapshot is generated from a secondary blockchain node, different from the blockchain node.

19. The system of claim 14 , wherein the snapshot is stored in a storage volume, wherein initializing the new blockchain node comprises mounting the storage volume to the new blockchain node.

20. The system of claim 14 , wherein the blockchain node is part of the blockchain node cluster for a blockchain network, wherein the blockchain node is selected for snapshot generation based on a set of health parameters, comprising at least one of a block height, latest block hash, total work on a blockchain synchronized with the blockchain node, or node telemetry.
