Hi, I wrote and published another article in Concerning Pharo: Understanding Base58 Encoding It is all about integers https://medium.com/concerning-pharo/understanding-base58-encoding-23e673e37ff6 This introductory article shows a bit how easy and how much fun it is to do integer and binary encoding and decoding as well as printing and parsing in Pharo. It also tries to explain Base58 Encoding from a first principles point of view. Sven
