Astar Network vs. Moonriver vs. Parity vs. Substrate Comparison Chart

Moonriver is a companion network to Moonbeam and provides a permanently incentivized canary network. New code ships to Moonriver first, where it can be tested and verified under real economic conditions. Once proven, the same code ships to Moonbeam on Polkadot. Quickly deploy your new or existing Solidity DApps to the Moonriver parachain — with little or no modifications — and gain easy access to the Kusama network. By mirroring Ethereum’s Web3 RPC, accounts, keys, subscriptions, logs, and more, Moonriver minimizes the changes required to run existing Solidity smart contracts on the network. Ethereum projects can simply replicate their DApp and deploy it to Moonbeam using Hardhat, Truffle, Remix, and other popular deployment tools. Quickly deploy your new or existing Solidity DApps to the Moonriver parachain — with little or no modifications — and gain easy access to the Kusama network.

Substrate Developer Hub, Blockchain development for innovators. Substrate is a modular framework that enables you to create purpose-built blockchains by composing custom or pre-built components. Create the perfect custom blockchain for your enterprise. That’s why we’ve built Substrate, a technology that makes it quick and easy to build the perfect blockchain for your needs. Substrate builds upon the achievements from the major blockchain protocols, and uses the lessons learned to give developers the latest technology to build flexible blockchains. Not every blockchain is suitable for every network. With Substrate, you can mix and match features to suit your project's needs. Substrate's modular design means you can reuse battle-tested libraries while building the custom components that matter most. Substrate is powered by best-in-class cryptographic research and comes with peer-to-peer networking, consensus mechanisms, and much more.
