Ethereum co-founder Vitalik Buterin shared a new proposal over the weekend that would radically overhaul the system that powers its smart contracts.Buterin's suggestion, which he posted on Ethereum's primary developer forum, involves replacing the Ethereum Virtual Machine, the software engine that powers programs on the network, with RISC-V, a popular open-source framework that offers built-in encryption and other benefits. .The EVM is a key piece of Ethereum's underlying design and has been seen as one of the main elements that helped the network succeed in a crowded field of other blockchains
