Ethereum has been experiencing scalability issues due to its limited transaction processing capabilities. To address this, various layer 2 scaling solutions have been proposed, one of which is StarkNet.

StarkNet is a layer 2 scaling solution for Ethereum that is designed to enable high scalability while maintaining the security and decentralization of the Ethereum blockchain. It is built on top of the StarkEx engine, which is a decentralized exchange (DEX) platform that uses zk-rollups to achieve high scalability.

StarkNet uses a different approach from other layer 2 scaling solutions such as Plasma and Optimistic Rollups. Instead of relying on fraud proofs or optimistic assumptions, StarkNet uses zero-knowledge proofs (ZKPs) to ensure the validity of transactions. ZKPs allow for the verification of transactions without revealing any confidential information, making StarkNet a highly secure and private layer 2 solution.

StarkNet is also highly customizable, allowing developers to create their own smart contracts and dApps. It supports both native and EVM-compatible programming languages, making it accessible to a wide range of developers.

One of the key advantages of StarkNet is its high throughput, with a capacity of up to 9,000 transactions per second (TPS). This is achieved through the use of zk-rollups, which batch multiple transactions together to reduce gas fees and increase efficiency.

StarkNet is currently in its alpha testing phase, and it is expected to be launched in the near future. Once live, it is expected to greatly improve the scalability and usability of the Ethereum blockchain.

In summary, StarkNet is a layer 2 scaling solution for Ethereum that uses zero-knowledge proofs to achieve high scalability, security, and privacy. With its high throughput and customizability, it has the potential to greatly enhance the Ethereum ecosystem and enable the development of new and innovative dApps.
