Join our [Telegram group](https://t.me/zold_io) to discuss it all live. The license is [MIT](https://github.com/zold-io/zold-score/blob/master/LICENSE.txt). This small Ruby Gem calculates the score for Zold nodes. To calculate a new Score you create an object first: ```ruby score = Zold::Score.new( host: 'example.com', port: 4096, invoice: 'MYPREFIX@ffffffffffffffff', strength: 6 ) ``` This score has zero value and the strength of six. Then you just ask it to calculate the next score: ```ruby n = score.next ``` That's it. This project is actively used in our [main Ruby repo](https://github.com/zold-io/zold). # How to contribute Read [these guidelines](https://www.yegor256.com/2014/04/15/github-guidelines.html).
