Abstract:
A method for generation of blocks for a partitioned blockchain includes: storing blocks comprising a partitioned blockchain, wherein each block includes a header and transaction entries; receiving transaction data entries for each of a plurality of subnets; generating a hash value of the header included in the most recently added block; generating a new block header, the new block header including the generated hash value, a timestamp, and a sequence of pairs including a pair for each of the plurality of subnets, each pair including a subnet identifier associated with the respective subnet and a merkle root of each of the transaction data entries received for the respective subnet; generating a new block, the new block including the generated new block header and the transaction data entries for each of the plurality of subnets; and transmitting the new block to a plurality of nodes associated with the partitioned blockchain.
