æternity Universe One
æternity is a public, open-source blockchain protocol that enables a platform for next-generation decentralized applications and high scalability. Its core components are written in the functional programming language Erlang, and its smart contracts are also functional. æternity has a stellar team of developers including Robert Virding - co-creator of Erlang, John Hughes - co-designer of Haskell, and Ulf Norell - co-designer of the Agda programming language for formal verification.
Unlike other blockchain platforms, the æternity protocol itself incorporates several essential technological features. State channels for off-chain scaling, oracles for real-world information, and a naming system for increased user-friendliness are all implemented on Layer 1. æternity also features SDKs in Java, GO, Phyton, Java, as well as a middleware and a development suite that streamline smart contract development.
