System and method to dynamically setup a private sub-blockchain based on agility of transaction processing

A system, comprising:

• at least one hardware processor configured to:
• receive a request to create a private sub-blockchain from a main blockchain, the request including a trust requirement and an agility requirement for executing transactions and exchanging messages on the private sub-blockchain;
• receive monitoring data from at least one of a plurality of validator nodes of the main blockchain, the monitoring data generated by monitoring the execution of transactions and the exchange of consensus messages by one or more of the plurality of validator nodes;
• determine a minimum number of validator nodes required to meet the trust requirement;
• identify a subset of the plurality of validator nodes of the main blockchain that meets the agility requirement based on the received monitoring data, the subset containing at least the determined minimum number of validator nodes required to meet the trust requirement;
• and
• create a private sub-blockchain of the main blockchain, the private sub-blockchain including the identified subset of the plurality of validator nodes of the main blockchain.

A non-transitory computer readable medium comprising instructions that when executed by at least one hardware processor, configure the at least one hardware processor to:

• receive a request to create a private sub-blockchain from a main blockchain, the request including a trust requirement and an agility requirement for executing transactions and exchanging messages on the private sub-blockchain;
• receive monitoring data from at least one of a plurality of validator nodes of the main blockchain, the monitoring data generated by monitoring the execution of transactions and the exchange of consensus messages by one or more of the plurality of validator nodes;
• determine a minimum number of validator nodes required to meet the trust requirement;
• identify a subset of the plurality of validator nodes of the main blockchain that meets the agility requirement based on the received monitoring data, the subset containing at least the determined minimum number of validator nodes required to meet the trust requirement;
• and
• create a private sub-blockchain of the main blockchain, the private sub-blockchain including the identified subset of the plurality of validator nodes of the main blockchain.
