There is a protocol called "Bancor Protocol" which is said to bring about automation of token liquidity and transaction price finding in Smart Contract.
To verify the usefulness of this protocol in your project, it is costly to write a smart contract program and implement the application.
When implementing applications with Ruby, I am making gem "bancor" to easily introduce and verify the Bancor Protocol.
In this presentation, we will talk about how developers build "token economy" on Ruby application using "bancor" and how to quickly verify effect.
