Quarkchain consist of two layers of blockchains
Elastic sharding blockchains (shards) as I layer
Root blockchain that confirms the blocks from the shards as II Layer
· Cross-shard transactions can be issued at any time, and confirmed in minutes. The throughput of cross-shard transactions increases linearly as the number of shards increases.
· There is only one account needed for all shards. All cryptocurrencies from different shards are stored in one smart wallet.
· Because a super-full node can be extremely expensive when TPS goes high, it allows multiple honest nodes forming a cluster running as a super-full node.
