Bancor（BNT）是什麼？

The Bancor protocol employs an automated market maker (AMM) smart contract to facilitate token trades against token liquidity pools without matching buyers and sellers. It has a built-in token called BNT that serves as the common price token to fulfill trades among other smart contract tokens. A portion of total trading fees are distributed to Liquidity Providers, or LPs, that deposit tokens into Liquidity Pools. Trading fees also protect user deposits from Impermanent Loss while minted and burned BNT supply maintains the constant market function for continuous token pricing.
The BNT token is the common price token that facilitates trades within the Bancor exchange. Instead of a central order book, Bancor fulfills trades between users and cryptoasset reserves called liquidity pools. Tokens in a liquidity pool are matched with a proportionate BNT amount to create pairs. The BNT serves as a common price among all unique tokens which creates markets for two otherwise illiquid tokens.
