The official implementation of the MultiversX blockchain protocol
...This implementation powers the MultiversX mainnet and supports advanced features like smart contracts, meta-transactions, and economic models suited for DeFi and enterprise use. Developers can build dApps using WASM-based smart contracts with performance and scalability in mind.
A permissioned Ethereum smart-contract blockchain node
Hyperledger Burrow is a permissioned Ethereum smart-contract blockchain node. It executes Ethereum EVM and WASM smart contract code (usually written in Solidity) on a permissioned virtual machine. Burrow provides transaction finality and high transaction throughput on a proof-of-stake Tendermint consensus engine. Burrow is a fully-fledged blockchain node and smart contract execution engine -- a distributed database that executes code. Burrow runs Ethereum Virtual Machine (EVM) and Web Assembly (WASM) smart contracts. ...
