RChain concurrency model compared to Ethereum, Cardano and EOS sequential model

RChain is the only smart contract platform that allows for safe concurrent execution of transactions at layer one. The maximum number of transactions that can be executed in one second is around 20 in the case of EOS. RChain uses a new programming language called rholang which follows pi-calculus principles developed by Robin Milner, Joachim Parrow and David Walker in the 90's. The platform is decentralized, with each computer within a network maintaining a replica of the virtual machine (VM)
