Quick TakeThere are two main types of sharding for blockchains: state and networkState sharding is typically more difficult to execute but scales blockchains more sustainably than network shardingContrary to the belief that shard chains are fully functional, most shard chains are currently mainly utilizing a single shard for smart contracts to reduce the technical complexityThe eventual growth in shard chains can serve as a useful precursor for the development of Ethereum 2.0 shard chains
