Sparse peer with transient participation

A method, comprising:

• connecting, by a sparse peer, to a blockchain network of a plurality of peers controlled by orderers;
• selecting, by the sparse peer, a subset of data to be replicated;
• specifying, by the sparse peer, data selection filters based on the selected subset of the data;
• providing, by the sparse peer, the selection filters to the plurality of the peers;
• receiving, by the sparse peer, blocks matching the selection filters over a gossip protocol from the plurality of the peers;
• constructing, by the sparse peer, a local ledger of the sparse peer from the received blocks;
• and
• bootstrapping the sparse peer based on the local ledger.

A non-transitory computer readable medium comprising instructions, that when read by a processor, cause the processor to perform:

• connecting to a blockchain network of a plurality of peers controlled by orderers;
• selecting a subset of data to be replicated;
• specifying data selection filters based on the selected subset of the data;
• providing the selection filters to the plurality of the peers;
• receiving blocks matching the filters over a gossip protocol from the plurality of the peers;
• constructing a local ledger of the sparse peer from the received blocks;
• and
• bootstrapping the sparse peer based on the local ledger.
