Bancor is a decentralized exchange protocol that is designed to increase liquidity for Ethereum and EOS tokens. The company has been at the center of the debate about Decentralized vs Centralized Exchanges, as well as the overall need of institutions to serve as a hub for decentralized networks. Their protocol, and exchange, enable any token to hold one or other additional tokens in reserve. Bancor allows conversions between tokens on their decentralized exchange with smart tokens that increase liquidity, and establish market prices for smaller tokens. Specifically, for those that do not have large trading volumes. Bancor tokens facilitate the exchange and act as a connective tissue, and have a centralizing effect on the exchange.
