Zk-rollup and StarkNet are two different technologies, but they both fall into the category of Layer 2 solutions and can be used to improve the throughput and scalability of the Ethereum network.
zk-rollup is a Layer 2 solution based on zero-knowledge proof, which realizes batch processing of transactions by creating an Aggregator Chain on the Ethereum network. In zk-rollup, transaction verification and processing are performed on the Aggregator Chain, and only the final result will be submitted to the Ethereum main chain, thereby improving the efficiency and security of transactions.
StarkNet is a Layer2 solution based on the StarkEx protocol, which uses zero-knowledge proofs to implement batch processing of transactions and reduces transaction costs through batch submission. Unlike zk-rollup, StarkNet is a more general Layer2 platform that can be used to build various types of decentralized applications, such as decentralized exchanges, games, financial services, etc.
Although zk-rollup and StarkNet are both Layer 2 solutions based on zero-knowledge proof technology, their implementation methods and application scenarios are different. At the same time, zk-rollup and StarkNet can also be used in combination with each other to achieve better scalability and efficiency. For example, zk-rollup can be used as a specific application in StarkNet to achieve more efficient transaction processing.
