Bitcoin

Bitcoin is a peer—to-peer payment system that uses a unit of the same name to account for transactions. Cryptographic methods are used to ensure the functioning and protection of the system, while all information about transactions between system addresses is available in clear text.

The minimum value transferred (the smallest amount of fragmentation) — 10-8 bitcoins — was named "satoshi" — in honor of the creator Satoshi Nakamoto, although he himself used the word "cent" in such cases[1].
