Bifrost (BNC) is a Polkadot-based parachain designed to provide liquidity and staking without nominating delays. A decentralized finance (DeFi) project in the Polkadot ecosystem, Bifrost allows users to deposit their staking tokens and mint vTokens (Staking Derivatives Voucher Token) to obtain staking liquidity, as well as receive staking rewards when a token is locked by a smart contract. With Bifrost, you can convert a proof-of-stake (PoS) token into a vToken; for example, DOT can be converted into vDOT.
