does anyone can explain the how Bancor protocol works in a nutshell? )
I've looked through the WP for 3 times
and I got nothing litteraly )
Bancor protocol enables the creation of “smart tokens” which independently handle their own liquidity and price discovery through their smart contracts. The method smart tokens use to do this is by holding a balance of another token (let’s use ETH as an example) so that the smart token can be purchased by sending the connector token (ETH) to the smart contract (this ETH is then added to the connector balance, and smart tokens are issued to the buyer) or liquidated by sending smart tokens to the smart contract (the seller then receives ETH from the connector balance and the smart tokens are destroyed) all without needing a second party to trade with. The price at which the smart token is bought or sold for any of its reserve tokens is set by an algorithm which balances the current connector balance with the current smart token supply, at a predefined Weight, which is a above 0 and up to 100%. The smart contract also recalculates its own price following each purchase (which causes price to increase) or liquidation (which causes price to decrease), in proportion to the transaction size. So, a larger purchase or liquidation will change the price more than a smaller one. This ensures that the connector cannot be drained and will always maintain their Weight of connector token balance in the contract. Thus, a smart token does not need to be listed in an exchange in order to be liquid and priced by the market.
Now they are not called Smart Tokens any more. They are called Liquid tokens.

On the other side, Bancor is getting more and more complex as it develops, so I'm getting a hard time myself to get all the details.
In just a few words, Bancor mainly uses a system of Bancor tokens with different properties and functions to create a pool of liquidity between classes of assets - at the moment just different ERC-20 tokens. This system uses the Bancor Protocol which contains a formula able to determine ("discover") the price of the assets in any moment. So when you buy or sell an asset against another you don't need a counterparty any more. The Bancor reserve is the counterparty and it's managed automatically by the Bancor protocol.
