Hello, I’ve uploaded the version 1.0 of the new ledger-lite library / gem. What’s Ledger Lite? It’s a hyper ledger accounting book for the distributed blockchain internet era; add your transactions one block at a time; transfer crypto(currencie)s and balance the accounts. Happy new year. Prosit 2018! PS: You might also enjoy the new (free online) Programming Cryptocurrencies & Blockchains (in Ruby) book @ Yuki & Moto Press.
