A distributed transaction system is provided including a group of validator nodes that are known to each other in a network but are indistinguishable to other network nodes. The validator nodes form a Committee including a Leader node and one or more Associate nodes configured to receive and process transaction requests, for example, to add new blocks to one or more blockchains. The Committee may be dynamically changed, such that new network nodes may be added to the Committee or may replace existing validator nodes. The Associate nodes also may coordinate with each other to select a new Leader node. The validator nodes in the Committee may be changed at a sufficient frequency to remove unreliable, unavailable, or otherwise untrusted nodes.

Systems and methods for selecting and utilizing a committee of validator nodes in a distributed system

The disclosed embodiments provide a distributed transaction system including a group of validator nodes that are known to each other in a network but are indistinguishable to other network nodes. The validator nodes form a Committee including a Leader node and one or more Associate nodes. The Committee may be dynamically changed, such that new network nodes may be added to the Committee or may replace existing validator nodes. The Associate nodes also may coordinate with each other to select a new Leader node. The disclosed embodiments reduce the distributed system's reliance on the stability of any particular node(s) in the network, as the validator nodes in the Committee may be changed at a sufficient frequency to remove unreliable, unavailable, or otherwise untrusted nodes. Further, the disclosed embodiments provide a scheme that helps ensure the Leader node, as well as the other Committee members, functions properly.
