Subspaces are individual identities within a community Space. Examples of this hierarchical structure:
- alice@nostr
- bob@bitcoin
- mike@x
Here, Alice, Bob, and Mike are subspaces or unique identities within their respective community spaces @nostr, @bitcoin, and @x.
The Spaces protocol is being built in two stages. Initially, launch of the base layer on the Bitcoin mainnet, which includes on-chain auctions for the top-level spaces.
Work on subspaces will begin after the mainnet launch and will be implemented as a soft fork.
Subspaces are key to scalability as they enable the creation of millions of individual identities within each community space. They have a much lower on-chain footprint, making them more accessible and affordable for everyone!
- Subspaces, unlike traditional domains, are sovereign and permissionless identities.
- Once issued, they cannot be taken down by their respective community.
- They can do 100% of their transactions on-chain if they wish treated the same as a parent space.
- They are cost effective to maintain.
While we work towards implementation, you can:
- Read the paper for initial design notes on subspaces.
- Experiment with subspacer, a tool that creates validity zk-proofs. These proofs attest that the subspaces trie was updated correctly, without revealing the individual changes.
- Checkout Fabric for storing records for spaces & subspaces off-chain.
