QuarkChain

QuarkChain: A High-Capacity Peer-to-Peer Transactional System

Welcome to QuarkChain wiki!

QuarkChain is a sharded blockchain protocol that employs a two-layer architecture - one extensible sharding layer consisting of multiple shard chains processing transactions and one root chain layer securing the network and coordinating cross-shard transactions among shard chains. The capacity of the network scales linearly as the number of shard chains increase while the root chain is always providing strong security guarantee regardless of the number of shards. QuarkChain testnet consistently hit 10,000+ TPS with 256 shards run by 50 clusters consisting of 6450 servers with each loadtest submitting 3,000,000 transactions to the network.
