Best Smart Contract Platforms for Quicknode

Bitcoin is an innovative payment network and a new kind of money. Bitcoin uses peer-to-peer technology to operate with no central authority or banks; managing transactions and the issuing of bitcoins is carried out collectively by the network. Bitcoin is open-source; its design is public, nobody owns or controls Bitcoin and everyone can take part. Through many of its unique properties, Bitcoin allows exciting uses that could not be covered by any previous payment system. Bitcoin transactions are secured by mathematics and energy. Cryptographic signatures prevent other people from spending your money. Energy spent by proof of work (PoW) prevents other people from undoing, rearranging or losing your transactions. So long as you take the required steps to protect your wallet, Bitcoin can give you control over your money and a strong level of protection against many types of fraud.

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.

BNB Smart Chain (BSC) is a blockchain platform developed by Binance, designed to enable decentralized applications (dApps) and smart contracts. It operates as a parallel chain to Binance Chain, combining high-speed transactions with the programmability of Ethereum-compatible smart contracts. BSC uses a Proof-of-Staked-Authority (PoSA) consensus mechanism, which enhances scalability and efficiency while reducing transaction costs. It is compatible with the Ethereum Virtual Machine (EVM), allowing developers to easily port dApps and projects from Ethereum. BSC has become a popular choice for decentralized finance (DeFi), gaming, and NFT ecosystems, offering users a fast, low-cost, and secure platform for blockchain-based innovations.

Polygon is a leading blockchain infrastructure designed to bring the speed, scalability, and efficiency of the internet to global finance. With over 5 billion transactions, 117 million active addresses, and a 99.99% uptime record, Polygon has become the trusted foundation for real-time payments, stablecoin transfers, and decentralized finance. The network enables instant settlement at near-zero cost, powering billions in digital asset movement worldwide. Its enterprise-ready infrastructure includes built-in wallets, onramps, and compliance tools that simplify blockchain adoption for businesses. Powered by POL, Polygon’s native token fuels transactions, staking, and security across its multi-chain ecosystem. Built for scalability, Polygon delivers the reliability and performance that modern financial systems demand.

The new scalability stack for Ethereum. Instant transactions and scalable smart contracts. Optimism is a Public Benefit Corporation (PBC): a for-profit corporation intended to produce a public benefit and operate in a responsible and sustainable manner. This means that we are obligated to balance the pecuniary interests of our stockholders with the best interests of those materially affected by our conduct, as well as a specific "public benefit charter" we incorporated with. The specific public benefit purpose of the Company is to enhance and enshrine fair access to public goods on the internet through the development of open source software. This charter represents our pledge to the Ethereum community to uphold its values by producing infrastructure which promotes the growth and sustainability of an ecosystem of public goods.
