# Key Terms To understand the tokenomics of BounceBit it helps knowing these key terms. * **BB:** The BB token is the native BounceBit platform asset * **Proof-of-Stake:** The consensus mechanism that selects, incentivizes and rewards validators who process transactions and create new blocks on BounceBit. * **Gas fees:** Gas fees are the transaction fees users pay on the BounceBit blockchain to submit transactions (e.g. sending or swapping BBTC) and execute smart contracts. They prevent spam and denial-of-service attacks. * **Dual-Token Staking:** Dual-Token is a mixed Proof-of-Stake mechanism. It uses two tokens to secure one network. BounceBit uses BB and combines it with BTC, which has lower volatility, deeper liquidity and more accessibility. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
