Bare 1-sat output

1 sat

A P2PKH output holding exactly one sat, with no envelope. It may carry an object made earlier.

What it is

The lock is plain P2PKH; what makes it different is the amount. Under the 1Sat Ordinals convention, a single sat can carry an inscription from the transaction that made it, through every transfer after. So a 1-sat output with no envelope of its own may still be an object, and a careful wallet keeps it out of coin selection until it knows.

Script pattern

  1. OP_DUP OP_HASH160 The P2PKH opening.
  2. <pubkey hash> 20 bytes: the owner's key hash.
  3. OP_EQUALVERIFY OP_CHECKSIG The P2PKH close.

The script is identical to P2PKH; the output's value is 1 sat.

How it is spent

The owner's signature, as P2PKH. To move the object with it, send it on as 1 sat.

Background

1Sat Ordinals arrived on BSV in 2023, adapting the ordinal idea to whole outputs of one sat. Wallets that follow it hold back every 1-sat output from payments, so an object is never spent as change by accident.
