Spaces are nice & memorable sovereign handles anchored in Bitcoin with minimal on-chain footprint. They are easier to share compared to an , and can be used to sign things just like a regular public key!
Spaces are anchored in Bitcoin, the most secure Proof-of-Work blockchain, and have the following properties:
Primary spaces are community identifiers, capped at ~3600 per year, acquired through permissionless auctions on the Bitcoin blockchain.
Each primary Space is a community that may issue sovereign handles off-chain known as subspaces.
Spaces AND subspaces (once allocated) are permissionless and as secure as Bitcoin itself! No bridges, slashing, or any kind of optimistic security.
The spaces protocol is designed with zk-light clients in mind making these identities verifiable on resource constrained devices.
Subspaces do not need to trust the community operator once allocated, and they can do 100% of their transactions on-chain if they wish.
Minimal on-chain footprint.
For full verification, you can sync the entire spaces protocol with a pruned Bitcoin full node on an old Raspberry PI. Bitcoin is the most secure Proof-of-Work blockchain today, and it's relatively lightweight compared to running an Ethereum node. The majority of ENS integrations trust centralized third-parties defeating the whole purpose of decentralized identities.
