Protocol
Lemma: the middle layer our products share.
Applications need privacy without opacity to the law, compliance without mass disclosure, and proofs that stay sound across the retention horizon. Lemma is that shared middle layer — consumed first by Proof of Reserves and tokenized-asset compliance.
Design
One problem, one object, two first consumers.
This is the interface both applications are built against.
Problem: institutions must attest solvency and policy execution continuously across regimes, without surrendering custody or privacy. Object: a selectively disclosable, post-quantum-ready protocol with executable policy and target succinct state proofs (history will fold; verification cost stays flat analytically, not measured on folded histories). First consumers: the two vertical applications on this site. All properties are target or specified; none are delivered today.

The Lemma protocol deck ships with the raise; until then, request it directly.
