1. A computer-implemented method of mining in a blockchain network, the blockchain network including a non-mining node and a plurality of mining nodes, the method comprising:
generating, by the non-mining node, a candidate block containing a plurality of transactions including a source transaction that includes a first output associated with the non-mining node and a miner transaction that includes the first output of the source transaction as an input and includes a second output associated with a first mining node;
determining a payload summary of the candidate block;
sending, to the first mining node, the payload summary, the miner transaction, and a first summary path for the miner transaction;
receiving, from the first mining node, a proof-of-work solution for the candidate block; and
propagating the candidate block on the blockchain network,
wherein the source transaction and the mining transaction are not propagated on the blockchain network and are not contained in a mempool prior to receipt of the proof-of-work solution for the candidate block.
