Altlayer is a decentralized layer-2 scaling solution for Ethereum. It is designed to address the scalability and high gas fee issues faced by the Ethereum network. Altlayer aims to achieve this by leveraging a unique architecture that combines rollup and sidechain technologies.

With Altlayer, transactions are processed off-chain, reducing the load on the Ethereum network and allowing for faster and cheaper transactions. By bundling multiple transactions together and submitting them as a single transaction to the Ethereum mainnet, Altlayer achieves scalability while maintaining the security and trustlessness of the Ethereum network.

Altlayer also introduces a novel concept called "arbitration liquidity," which allows for the resolution of disputes between users and applications in a more efficient and cost-effective manner.

Overall, Altlayer aims to provide a more scalable and affordable infrastructure for decentralized applications (dApps), enabling them to reach a wider user base and improve the user experience on the Ethereum network.
