Best Smart Contract Platforms for Harmony

Ethereum is the community-run technology that powers the cryptocurrency, Ethereum (ETH), and thousands of decentralized apps. Ethereum is a technology that allows for digital money, global payments, as well as applications. The community has created a vibrant digital economy, new ways for creators of online income, and many other benefits. It's accessible to anyone, anywhere in the world. All you need is the internet. Today, billions cannot open bank accounts and others have their payments blocked. The Ethereum decentralized finance system (DeFi), never sleeps nor discriminates. You can send, receive and borrow money anywhere in the world with an internet connection. We can now access 'free' internet services without having to give up our personal data. Ethereum services are available by default. You only need a wallet. These services are free and easy-to-set up. They can be controlled by you and work without your personal information. Stake your ETH to become an Ethereum validator. Staking is a public good for the Ethereum ecosystem. You can help secure the network and earn rewards in the process.

BNB Smart Chain is a blockchain-based platform developed by Binance. It was designed to allow decentralized applications (dApps), and smart contracts. It is a parallel chain that operates alongside Binance Chain. It combines high-speed transactions and the programmability provided by Ethereum-compatible smart contract. BSC uses a Proof-of-Staked-Authority (PoSA) consensus mechanism, which enhances scalability and efficiency while reducing transaction costs. It is compatible with Ethereum Virtual Machine (EVM), which allows developers to easily port projects and dApps from Ethereum. BSC is a popular platform for Decentralized Finance (DeFi), Gaming, and NFT ecosystems. It offers users a fast and low-cost platform for blockchain-based innovation.

API3's secure, decentrally managed data feeds make it easy to create powerful decentralized applications. API3 data feeds (dAPIs), aggregate data from first party oracles. They are operated by some the most reputable API providers in the world. Transparent, decentralized, trust-minimized governance. Instead of third-party intermediaries, first-party oracles. Users are covered against data feed failures For any smart contract platform, real-world data. API3 data feeds are managed by an open DAO made up of industry experts, stakeholders, and project partners. This allows dAPIs maximum transparency, minimal trust in centralized operators, as well as no centralized attack surface. API token holders can participate directly in the governance of the project by purchasing API3 tokens and staking them into the API3 insurance contract. This grants them shares in API3 DAO.

Connect your smart contract with the outside world. Chainlink's decentralized Oracle network provides reliable, tamperproof inputs and outgoings for complex smart contract on any blockchain. Start building your universally connected smart contracts. To connect high-quality and accessible data/APIs to any smart contracts, use decentralization, trusted data, premium data, cryptographic proofs, and trust nodes. A flexible framework can be used to retrieve data from any API, connect to existing systems, and integrate any blockchain, both now and in the future. Integrate battle-tested and proven oracle solutions that have secured billions in value for leading blockchain projects. Independently verify Chainlink's open source code, performance of its oracle network, and quality of individual node operator.
