A method for improving consensus in a blockchain network through decentralized grouping includes: identifying, by each node of a plurality of nodes in a blockchain network that manages a blockchain, a plurality of groups, where each is comprised of a subset of nodes; generating, by each node in each subset of nodes, a new block for the blockchain; performing, by each subset of nodes, a first consensus operation among all nodes in the subset of nodes for the new block generated by in the subset of nodes to identify a group consensus block, where each node in the subset of nodes receives the group's group consensus block; and performing, by the blockchain network, a second consensus operation among all groups for the identified group consensus block to identify an overall consensus block, where a majority of groups of the plurality of groups receives the overall consensus block.

A method for expedited confirmation and inclusion of orphaned transactions in a blockchain network includes: receiving new blockchain transactions, confirming each of the new blockchain transactions, receiving a new block accepted for the blockchain that includes only a subset of the confirmed blockchain transactions, generating a subsequent new block that includes at least the orphaned transactions that were not included in the received new block, and transmitting the subsequent new block to one or more other nodes in the blockchain network.
