Best Smart Contract Platforms for Substrate

Polkadot is a blockchain network being built to enable Web 3.0, a decentralized and fair internet where users control their own data and markets prosper from network efficiency and security. Polkadot was founded in 2016 by Gavin Wood, former Co-Founder and CTO of Ethereum. Polkadot’s technology addresses the major issues that have stymied blockchain adoption in recent years. Polkadot’s software development toolkit, Substrate, created by Parity Technologies, makes it easy for blockchain developers to build their own custom, fit-for-use blockchains. Polkadot also enables multiple blockchains to communicate between each other, allows for easy upgradeability, and introduces “shared security”, a plug-and-play network security model that allows developers to focus on the technology and avoid spending time and resources recruiting a set of operators to run a new blockchain.

Ethereum is the community-run technology powering the cryptocurrency, ether (ETH) and thousands of decentralized applications. Ethereum is a technology that's home to digital money, global payments, and applications. The community has built a booming digital economy, bold new ways for creators to earn online, and so much more. It's open to everyone, wherever you are in the world – all you need is the internet. Today, billions of people can’t open bank accounts, others have their payments blocked. Ethereum's decentralized finance (DeFi) system never sleeps or discriminates. With just an internet connection, you can send, receive, borrow, earn interest, and even stream funds anywhere in the world. Today, we gain access to 'free' internet services by giving up control of our personal data. Ethereum services are open by default – you just need a wallet. Stake your ETH to become an Ethereum validator.

No need to rewrite or reconfigure your smart contracts. Moonbeam is much more than just an EVM implementation: it’s a highly specialized Layer 1.5 chain that mirrors Ethereum’s Web3 RPC, accounts, keys, subscriptions, logs, and more. The Moonbeam platform extends the base Ethereum feature set with additional features such as on-chain governance, staking, and cross-chain integrations. Address segments of your market that are out of reach on Ethereum due to gas prices. Enjoy a “first mover” advantage by deploying early to Polkadot’s rapidly expanding parachain ecosystem. Built-in integrations for assets like DOT and ERC-20s, and infrastructure services like Chainlink and The Graph.

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.

Write Ethereum-compatible smart contracts in popular programming languages, & run them much faster, on Substrate. A decentralized open source business model funded by developer treasuries on participating blockchains. All existing Ethereum smart contracts work on ParaState’s Ewasm VM (Pallet SSVM) without any change. ParaState expands the developer ecosystem by supporting 20+ programming languages to create Ethereum-compatible smart contracts. Examples include generic programming languages such as Solidity, Fe, Rust, and JavaScript, and domain-specific languages (DSLs) such as MOVE, DeepSEA, and Marlowe. Substrate-based blockchains, such as Polkadot parachains, already enjoy much higher TPS (transactions per second) than Ethereum. For a smart contract platform, compute performance is more important than TPS throughput. Try deploying smart contracts on ParaState.
