Ethereum flavored WebAssembly, eWASM, just ethereum’s version of the WASM (which stands for WebAssembly) code, created by the World Wide Web Consortium (W3C), the team of developers responsible for maintaining and standardizing the web. eWASM will allow developers to code in multiple programming languages — not just the ethereum-specific language, Solidity — and is said to come with a host of performance enhancements as well.
