Where it came from

An original Bitcoin Universe protocol, published 2025.

Where the specification lives

The specification and reference documentation for Witness Circles live in bitcoinuniverseio/witness-circles and are published at https://bitcoinuniverseio.github.io/witness-circles/. That site is the authority. This page exists so you can find it and compare it with the rest of the estate.

Bitcoin Universe indexes or implements it in bitcoinuniverseio/index-witness-circles.

Support in Bitcoin Universe products

Witness Circles has no marketplace entry in the Core protocol registry, so no Bitcoin Universe product implements a trade path for it. Where a Universe indexer exists, the data is available through that indexer rather than through a product surface.
