Subject: [bitcoindev] Scalable & Permissionless Bitcoin CA

I’d like to discuss a project we’re developing called Spaces, for creating 
a scalable & permissionless ~250KB Bitcoin Certificate Authority. We’re 
working on building a zk light client for the protocol using RISC0 zkVM[0] 
and the protocol uses client-side validation. Leveraging Bitcoin & ZK, it 
seems we could finally get decentralized PKI that works well and 
lightweight enough to verify by end-users.

What makes Spaces scalable is that it introduces a concept of “subspaces” 
which are off-chain entities that have great autonomy. It is not exactly 
like zk-rollups as the data itself is off-chain - although it may not 
exactly fit into “validium” either as data availability itself is not a 
major issue. Users hold their own inclusion proofs. The commitments posted 
on-chain have a lifetime during which they’re able to transact on-chain and 
off-chain.

We’re at an early stage and welcome your feedback. For more technical 
details:
