BNB Smart Chain

BNB Smart Chain (BSC) is a high-performance, community-driven blockchain platform built to support scalable and user-friendly decentralized applications (dApps), with a particular focus on decentralized finance (DeFi). It is fully compatible with the Ethereum Virtual Machine (EVM), enabling developers to deploy existing Ethereum smart contracts and use familiar Ethereum tooling. BSC achieves faster finality and lower transaction fees by employing a Proof of Staked Authority (PoSA) consensus mechanism, which combines delegated staking and authority-based block production.

The chain operates with a limited set of 21 validators elected through staking governance, balancing decentralization and efficiency. BNB is the native token used for gas fees and staking, securing the network and enabling participation in on-chain governance. BSC supports a rich ecosystem including bridges for cross-chain asset transfers, staking solutions, MEV protection, and developer tools such as JSON-RPC APIs, native dApp bindings, and node operation utilities.

Developers can run full nodes using the open-source BSC client, which is a fork of go-ethereum, and interact programmatically via standard JSON-RPC endpoints over HTTP, WebSocket, or IPC. The platform provides extensive documentation, example projects, and community programs like hackathons and grants to accelerate dApp development. BSC's ecosystem includes over 92,000 issued assets and supports thousands of projects, making it a popular choice for DeFi and Web3 builders seeking scalability and low fees.
