BNB is the native utility and staking asset of the BNB Chain ecosystem, used as the fee (“gas”) token for on-chain execution and as the economic unit for validator security and governance. After migrating from an original ERC-20 form to become the native asset of Binance Chain mainnet (April 18, 2019), BNB’s role expanded with the launch of the EVM-compatible BNB Smart Chain (September 2020), enabling smart-contract applications and tokenized asset issuance at scale. Network security is anchored in Proof of Staked Authority (PoSA), a stake-weighted validator model designed for low-latency finality, with block production concentrated in a small active set (top 21 by stake). BNB’s supply policy incorporates systematic reduction via BNB Auto-Burn (quarterly, based on BNB price and blocks produced) alongside a real-time burn mechanism that destroys a portion of gas fees (BEP-95). Since February 15, 2022, Binance Chain and BSC have been unified under the BNB Chain brand to reflect BNB’s role as the core settlement and security asset across the ecosystem.
