Abstract
The present disclosure provides a blockchain sharding method, system, and server based on locally repairable system codes. The blockchain sharding system includes k original shards and n−k encoding shards. In each round of consensus, each original shard and m corresponding encoding shards form a local verification group (m<<n−k), and each encoding shard and t original shards participating in generation of the encoding shard form local recovery groups (t<<k). The local verification group is responsible for verifying whether a to-be-verified transaction is legitimate. When a single shard in the verification group is corrupted, the remaining m shards can reach a consistent verification result. According to the principle that the minority is subordinate to the majority, the verification group can still correctly verify the legitimacy of the transaction.
