Abstract:Sharding technology is seen as the most likely solution to the scalability of blockchain, by dividing nodes into smaller groups called shards that transactions can be processed in parallel. However, most sharding scheme adopted random sharding to avoid the aggregation of malicious nodes, while the performance difference between nodes is ignored, resulting in the transaction efficiency gap of each sharding. In this paper, we propose BEST, a blockchain sharding scheme with both security and effiency, nodes are a… Show more
