Phase III · Beyond
Closure L1 is the chain underneath the substrate. Every inference, every mutation, every grant of agency settles on a network where coherence is the consensus rule. Not another DePIN of compute or storage — the substrate itself is the network.
PoC
Proof of Closure is the L1 consensus mechanism: transitions finalize through Coverage-Based Finality — stake-weighted epistemic coverage — the way Proof of Stake uses block validation. What settles is coherence over the closure index, not first-past-the-post hashing.
L1
A new kind of DePIN. Compute, identity, and value all proved against the substrate. The chain does not store what happened — it stores what was true.
χ
Every callable execution unit is signed, addressable, reproducible. Models, prompts, derivations, decisions — all on-chain, all verifiable. The model is the chain. The chain is the model.
Why now
When intelligence is physics, the only honest infrastructure is one where every step is checkable. Closure Network is that infrastructure. The L1 is not a coin. It is the ledger of coherence.
