Satributes 101: how RareSats classifies rare satoshis
A quick tour of the rare-sat categories RareSats detects from public on-chain data — what they mean, where they came from, and why collectors care enough to put them on a watch face.
"Satribute" is shorthand for satoshi attribute — a property a single satoshi acquires from its position on the Bitcoin timeline. RareSats currently recognizes more than 20 of them. Here's a tour of the most popular categories.
Block-era satributes
- Block 9 / Block 78 — sats minted in the very first weeks of Bitcoin, often associated with Satoshi-era miners.
- Vintage — sats minted before block 1,000.
- Nakamoto — sats from blocks attributed to Satoshi.
- First TX — sats from the first non-coinbase transaction.
Numerical satributes
- Palindrome — the satoshi number reads the same forwards and backwards.
- Alpha / Omega — the first or last sat of its block.
- Pizza — sats traced to the famous 10,000 BTC pizza transaction.
Tier satributes
RareSats also exposes the canonical Ordinals rarity tiers: Common, Uncommon, Rare, Epic, Legendary, Mythic, plus their "Black" variants for the rarest first-of-cycle satoshis.
How RareSats uses them
When you add a public address (or a specific sat number), the app queries public on-chain data and emits a satribute breakdown locally. You can then filter your collection, set a sat as an Apple Watch face, or generate a wallpaper — all rendered on your device.
