ZK-SNARK Layer Sharding refers to a method of scaling blockchain networks by combining zero-knowledge succinct non-interactive arguments of knowledge (ZK-SNARKs) with sharding. ZK-SNARKs allow one party to prove the validity of a statement without revealing the underlying data. This feature enhances privacy and reduces the amount of information that needs to be processed by validators. Sharding, on the other hand, divides a blockchain into smaller, manageable pieces called shards. Each shard can process transactions and smart contracts independently, increasing the overall throughput of the network.When combined, ZK-SNARKs and sharding improve efficiency and scalability. By using ZK-SNARKs, each shard can generate compact proofs of its transactions, enabling the main chain to verify these proofs without processing all transactions individually. This results in faster processing times while maintaining security and privacy, allowing a blockchain to handle a larger volume of activities without becoming congested.
