Welcome | Spaces Guide
Spaces are community identifiers; think of them as top-level domains such as ".com", ".org", and ".net". Every Space is represented as a Bitcoin UTXO (Unspent Transaction Output), and can operate millions of decentralized identities underneath called subspaces. There are only about 3600 community spaces released per year, acquired through permissionless auctions on the Bitcoin blockchain.
Unlike Bitcoin-themed naming systems such as ones based on RSK and STX, Spaces are Bitcoin UTXOs secured directly by the Bitcoin blockchain and have the following properties:
Spaces are community identifiers, capped at ~3600 per year, acquired through permissionless auctions on the Bitcoin blockchain.
Spaces AND subspaces (once allocated) are permissionless and as secure as Bitcoin itself! No bridges, slashing, or optimistic security.
The spaces protocol is designed with zk-light clients in mind making these identities verifiable on resource constrained devices.
