Binance-Peg WETH (WETH)
BNB Chain is a blockchain network that is closely associated with the Binance cryptocurrency exchange. It was created to facilitate the development of a range of decentralized applications (DApps) and provide users with a robust platform for various blockchain activities. BNB Chain serves as the foundation for Binance's ecosystem, offering enhanced performance, scalability, and security.
History of BNB Chain
BNB Chain was initially launched as Binance Chain in April 2019 by Binance, one of the largest cryptocurrency exchanges in the world. The primary purpose of Binance Chain was to enable the issuance and exchange of digital assets in a decentralized manner. Binance Coin (BNB), originally an ERC-20 token on the Ethereum network, was migrated to this chain to become its native coin.

In September 2020, Binance Smart Chain (BSC) was introduced as a parallel chain to Binance Chain. BSC was designed to support smart contracts and operate with Ethereum-compatible programming languages. This dual-chain architecture allowed users to benefit from the fast transaction capabilities of Binance Chain while also utilizing the smart contract functionality of BSC.
In February 2022, Binance announced a rebranding of both Binance Chain and Binance Smart Chain into BNB Chain. This rebranding reflects the chain’s focus on building a broader ecosystem around Binance Coin (BNB) and supporting the growth of decentralized finance (DeFi) and the metaverse.
Architecture and technology
Dual-chain architecture
BNB Chain operates on a dual-chain architecture, comprising the Binance Chain and Binance Smart Chain. This architecture allows users to access the fast and efficient trading capabilities of Binance Chain, while also benefiting from the smart contract functionality provided by Binance Smart Chain.
Consensus mechanism
BNB Chain uses a Proof of Staked Authority (PoSA) consensus mechanism. This is a hybrid consensus model that combines elements of both Proof of Stake and Proof of Authority. It allows for faster block times and lower transaction costs, making it an attractive choice for developers and users seeking efficient blockchain solutions.
Cross-chain compatibility
A key feature of BNB Chain is its cross-chain compatibility, particularly with Ethereum. This compatibility is achieved through the implementation of Ethereum Virtual Machine (EVM) support on Binance Smart Chain. As a result, developers can easily port their Ethereum DApps to BNB Chain with minimal modifications, expanding the reach and usability of their applications.
Use cases and applications
Decentralized finance (DeFi)
BNB Chain is a popular platform for decentralized finance (DeFi) applications. Its scalability and low transaction fees make it an ideal environment for projects offering lending, borrowing, yield farming, and other financial services. Numerous DeFi platforms, such as PancakeSwap and Venus, have been launched on BNB Chain, contributing to its growing ecosystem.
Non-fungible tokens (NFTs)
The BNB Chain also supports the creation and trading of non-fungible tokens (NFTs). Artists, creators, and collectors can leverage the chain’s capabilities to mint, buy, sell, and trade unique digital assets. The chain's compatibility with Ethereum standards ensures that NFTs on BNB Chain can be easily integrated with existing NFT marketplaces.
Gaming and metaverse
With the rise of blockchain gaming and metaverse platforms, BNB Chain provides an efficient and scalable infrastructure for developers looking to build immersive virtual experiences. The chain's low fees and fast transaction times make it an attractive option for game developers and metaverse creators.
