Hello, hint: would love to see a write-up about any gem (e.g. kittyverse, blockchain-lite, universum, ed25519, etc.) from the Ruby Blockchain Programming books in the Best of Crypto Books collection. Join us in the new year in 2021 and claim a free day in the upcoming Ruby Blockchain Week 2021, January 3rd to January 9th - 7 Days of Ruby (Crypto) Gems. Why not highlight a blockchain / cryptos gem with your write-up in the ruby universe? Yes, you can! Cheers. Prosit 2021!
