View source for Ethereum-flavored Web Assembly (eWASM)

* From a [https://media.consensys.net/the-roadmap-to-serenity-bc25d5807268 post] about the Serenity [[roadmap]]:
''"In Phase 2, the functionality of [[Ethereum (ETH)|Ethereum]] 2.0 comes together. With the introduction of a new [[Ethereum Virtual Machine (EVM)|Virtual Machine]] — Ethereum-flavored [[WebAssembly|Web Assembly]] (eWASM) — shard chains evolve from fairly rudimentary data markers to fully-functional transactional chains, capable of scaling the Ethereum network.''

''In order for a [[blockchain]] ecosystem to operate, nodes must execute transactions and [[Smart Contract|smart contracts]] in a virtual machine. Ethereum 1.0’s virtual machine was called the Ethereum Virtual Machine ([[EVM]]). With the switch to Ethereum 2.0 and the Beacon Chain, the network’s virtual machine will be upgraded to eWASM, a virtual machine based off Web Assembly, which is defined by the World Wide Web Consortium (W3C) as an open-source standard. Because WASM supports a number of coding languages, eWASM could allow [[smart contracts]] written in any language to be executed on Ethereum, as opposed to just ones written in [[Solidity]] in today’s EVM."''

''"Ewasm will replace the [[EVM]] as the state execution engine of the [[Ethereum]] network and is expected to be one of the final aspects of Eth 2.0 to be integrated. Ewasm (Ethereum WebAssembly), is a “restricted subset of Wasm” that has been modified specifically for the Ethereum network. One of the major targets is to provide an EVM transcompiler and a metering injector, preferably as an Ewasm [[contract]].[https://github.com/ewasm/design. ⁶] Another is a clear specification of the Ethereum interface and Ewasm contract semantics.[https://github.com/ewasm/design. ⁶] Finally, the team aims to implement an Ewasm backend for the [[Solidity]] compiler and to provide instructions and a library for writing contracts in C and [[Rust]].[https://github.com/ewasm/design. ⁶] The differences between Ewasm and wasm can be thought of in the following way: Ewasm = Wasm — nondeterminism (floating point) + metering + EEI methods (used to interact with Ethereum). Ethereum will join projects like [[Polkadot]], [[Cardano]], [[EOS]], [[Tron]], [[Spacemesh]] and [[NEAR]] protocol, who have either already adopted or are in the process of adopting Wasm.⁹"''[[Category:Jargon/Various]]
