SNS

Sats Name Service (SNS) is a decentralized naming protocol on Bitcoin. Users register human-readable names (like alice.sats) by inscribing them through Ordinals — a Bitcoin-native alternative to DNS.

Key Concepts​

  • Names — Full registered name including domain (e.g., alice.sats)
  • Domains — Namespace suffixes (e.g., .sats, .btc)
  • Namespaces — Top-level domains registered through inscriptions
  • First-come, first-served — First valid inscription for a name owns it

What You Can Query​

Rebar Data indexes all SNS registrations:

  • Look up any registered name and its inscription details
  • List all names under a domain
  • Browse registered namespaces
  • Verify indexer state through cryptographic hashes
