The Bancor protocol
is created of a serie of smart contracts “liquidity pools” that are designed to pool liquidity and perform peer-to-contract trades in a single transaction
When creating or staking in a Bancor pool, users do so in equal values of ERC20 token + BNT, or EOS token + BNT.
Bancor allows users to instantly convert between two tokens without needing a counterparty to the trade.
The Bancor network is a open source and closed source software.
Bancor is a interesting platform with a great team !
