The Data Layer is a decentralized, permissionless protocol built on Synternet that serves as the customizable execution layer between all blockchains, enabling developers instant access to any cross-chain data. It uses a pub-sub (publish-subscribe) framework where data providers can stream live data to applications and smart contracts.
This eliminates the computational burden and centralization risks of traditional request-reply oracle methods. The Data Layer provides real-time, ultra-low cost data delivery without the need of middlemen.
