The name 'Karbo' is derived from Ukrainian word 'karbovanets', that comes from an ancient way of recording settlements or debts by marking wooden stick called 'tally stick' or 'tally' with a system of notches that was very popular in the Mediaeval Europe from Antiquity up to the first decades of XX century. The stick would be split in half, down its length from one end to the other. The debtor would retain half, called the 'foil'. The creditor would retain the other half, called the 'stock'. Because wooden stick has natural and distinctive irregularities, the two halves would match only each other providing simple and effective protection against forgery. The way medieval tally sticks system worked resembles how blockchain works. Hence comes the name 'karbovanets' and its shortened version 'Karbo'. The 'karbovanets' has been a distinct unit of currency in Ukraine during three separate periods in its history. Nowadays it is obsolete and replaced by Ukrainian Hryvnia. 'Karbovanets' therefore is a very well-known word, with very strong associations with 'money' not only in Ukraine but also in Russia and other neighboring countries. It sounds familiar to people, which makes it more easy to adopt. It was resurrected in the digital form of cryptocurrency as people’s unofficial, independent exchange medium.
Sooner or later people will realize that something in the ideas of people opposing corruption regimes was about real unrestrained P2P electronic transfers without censorship. And it turns out that there are only a couple of coins that meet these requirements in the world. And it is impossible to create the same coin as Karbo with ease. The 5 years of fair distribution of emission, the 5 years of bug fixes and code improvements, and the 5 years of a devotion and demonstration by developers that they are ready to work on a project is impossible to get in one day. Reputation cannot be bought, it can only be earned by time.
