Rare Sats Clock: watch the next rare sats come into existence

Bitcoin continuously produces satoshis. But some occupy a special position in the structure of the network.

According to Casey Rodarmor’s rarity classification, certain satoshis are considered rare because they correspond to periodic Bitcoin events:

  • Uncommon: the first satoshi of a block;
  • Rare: the first satoshi of a difficulty adjustment period;
  • Epic: the first satoshi of a halving period;
  • Legendary: the first satoshi of a cycle where a halving and a difficulty adjustment coincide.

To visualize these events, we created the Proof of Sats Rare Sats Clock.

The tool works like a Bitcoin clock: it shows when the next satoshi of each rarity level will be mined, its expected serial number, and the progress until its creation. It also shows how many sats of each rarity level have already been produced compared with the total number that will ever exist.

Bitcoin Core + math

What makes the Rare Sats Clock special is that it doesn’t use any Ordinals indexer.

It connects directly to our Bitcoin Core node. Using block height, block subsidies, and the halving schedule, a calculation layer determines the serial numbers of future satoshis.

The guilloché patterns displayed by the clock are generated using the same engine as the Proof of Sats cards.

Uncommon. Rare. Epic. Legendary.
