The Blockchain for Domain Based Static Sharding

摘要

Blockchain is the shared distributed ledger to record the history of transactions. In blockchain network, nodes validate the transactions and reach the consensus on the ordered transactions. The more transactions are happened, the more processing powers of nodes are needed. Shard is introduced to blockchain for processing the multiple transactions in parallel. In this paper, we propose the blockchain for a domain based static sharding. We split a blockchain into multiple shards based on the domain. In each shard, nodes validate the multiple transactions concurrently and keep the shard's ledger separately. With this, it can be processing of low-latency transaction. Also, by changing the composition of committee members that validate blocks dynamically, we can enable the blockchain to be more trust.
