Database mergeable ledgers

Abstract:

An example operation may include one or more of generating, by a block generator, modified blocks for source ledgers, receiving a merge request to merge a plurality of source ledgers into a merged ledger, identifying the plurality of source ledgers, generating a genesis block from modified blocks of the identified source ledgers, ordering blocks, by a committer node or peer, in the merged ledger based on the genesis block, and validating a block order in the merged ledger.
