Zero-Knowledge (ZK) Rollups are a layer-2 scaling solution designed to improve the scalability and efficiency of blockchain networks.
They work by aggregating many transactions into a single batch and using zero-knowledge proofs to verify that the batch is valid without revealing the individual details. This helps reduce the load on the main blockchain, significantly lowering transaction fees while maintaining security.
ZK Rollups offer an efficient way to process transactions, increasing the blockchain’s capacity while ensuring privacy and scalability.
Blockchain rollups are a critical Layer-2 scaling solution designed to increase Ethereum's transaction throughput without sacrificing decentralization or security. They work by "rolling up" or bundling numerous off-chain transactions into a single, compressed representation.
A data structure called a Directed Acyclic Graph (DAG) is used in blockchain technology and computer science to organize and represent information without cycles or loops. It is a graph in which no pathways lead back to the beginning point and where edges have a distinct direction.
