BLOCK CHAIN POWER TRANSACTION SYSTEM, CONSENSUS METHOD, DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/040796
Kind Code:
A1
Abstract:
Provided in the present invention are a block chain power transaction system, a consensus method, a device and a storage medium. The block chain power transaction system comprises reputation modules, a shard partitioning module, intra-shard consensus modules and a cross-shard consensus module. The shard partitioning module is used for partitioning nodes into a plurality of shards according to a reputation value of each node in the system and a region where the node is located; the reputation modules consist of reputation chains and are used for calculating a reputation value of each node in a shard on the basis of work data of the node; the intra-shard consensus modules are used for verifying node transactions in the shard by means of an intra-shard consensus algorithm on the basis of node transaction information in the shard, and for proposing cross-shard transactions for nodes in the shard; and the cross-shard consensus module is used for verifying the cross-shard transactions by means of a multi-level cross-shard consensus mechanism. The present invention compiles nodes into shards on the basis of the reputation mechanism, thus ensuring the security in shards; and verifying cross-shard transactions by means of the multi-level cross-shard consensus mechanism can ensure safe and highly-efficient node transactions.
