Cachee is AI-powered distributed cache infrastructure for Polygon zkEVM sequencers, provers, bridges, rollup-as-a-service stacks, and L2 indexers. Evidence-backed outcome caching eliminates duplicated STARK proof verification, cuts recursive composition cost, and removes bridge-message replay. Downstream systems independently verify the cached result without re-running the proof and without trusting the cache operator. H33-74 attaches a 74-byte post-quantum evidence reference to each cached proof outcome; H33's cryptographic replay reconstructs the trust path. Cachee stores and serves across the industry's migration to PQ-secure proof systems.
The H33-74 evidence element — not Cachee — lets independent parties trust each cached proof outcome without trusting the cache operator. That single property converts zkEVM verification from a per-system cost into a shared, portable asset — the foundation of distributed verification infrastructure.
— The category shift
zkEVM proofs are designed to compress execution into something a verifier can check in milliseconds instead of milliseconds-per-transaction. That works — but "check in milliseconds" still gets paid millions of times across the modern zk ecosystem. Sequencers verify proofs before posting. Bridges re-verify on the destination chain. Rollup-as-a-service operators verify on customer infrastructure. Indexers re-verify on every reorg or schema migration. Exchanges re-verify before crediting deposits.
The waste is structural. A single STARK proof can be 200–500 KB. Its verification involves polynomial commitment checks, FRI queries, hash chains, and pairing operations that — while fast — are non-trivially expensive when paid per consumer per proof. Recursive composition compounds the problem: a proof of proofs still has to be verified by every downstream party.
The Polygon zkEVM protocol didn't pick a wasteful design. Modern zk infrastructure has scaled the cost of verification to the point where verification itself is the bottleneck. Every new consumer pays the full re-verification tax.
These are the operational line items zkEVM teams pay for every day. Each one collapses from per-consumer → per-attestation with portable verification receipts.
A single cached proof verification anchors the source of truth for every downstream verifier. The post-quantum attestation is what makes each cached outcome independently verifiable without trusting Cachee — the H33-74 evidence reference, not the cache, anchors trust — eliminating the per-verifier STARK re-execution tax.
Cachee does not generate attestations. Cachee does not verify them. The architecture works because three independent layers compose: Cachee stores. H33-74 attests. Replay reconstructs.
This three-layer composition is what “verifiable computation caching” actually means: not Cachee acting as a trust anchor, but Cachee as the high-speed delivery layer for outcomes that H33-74 makes independently verifiable.
Modern zk infrastructure mixes hash-based primitives (which are PQ-secure) with elliptic-curve primitives (which are not). Pairings, KZG commitments, and EC-based recursion all assume discrete-log hardness — the same assumption that quantum computers are expected to break.
Cachee's attestations are post-quantum from inception. The 74-byte verification receipt is signed by three independent post-quantum primitives: ML-DSA (lattice), FALCON (NTRU lattice), and SLH-DSA (stateless hash). Breaking the attestation requires breaking three independent mathematical bets simultaneously.
The practical consequence: cached zkEVM verification receipts remain portable through the industry's migration to PQ-secure proof systems. Rollups, bridges, and prover networks built against Cachee today don't need to redo their trust assumptions when quantum computers arrive — or when NIST tightens the standards, or when an EC-side vulnerability is disclosed.
For long-lived zk infrastructure — settlement layers, restaking-backed prover markets, regulatory-grade rollups, multi-year proof archives — post-quantum portability isn't a feature. It's the only honest design choice.
Concrete surfaces where portable proof verification pays for itself immediately.
The pattern repeats anywhere a zkEVM proof is verified more than once: STARK proof caching, SNARK proof caching, recursive proof composition, bridge verification, sequencer compute, on-chain verification gas, prover network economics, L2 indexing, large proof delivery. Cachee compresses the verification cost from per-consumer to per-attestation — post-quantum, portable, and reusable.
Polygon zkEVM doesn't live alone. Ethereum L1 settles its proofs. Bitcoin-anchored sidechains consume its bridge messages. Solana programs read its rollup checkpoints. Every one of those systems pays the full zkEVM verification cost today — and pays it per-consumer, per-chain, per-relay.
H33-74's evidence primitive — served by Cachee — is chain-agnostic. The 74-byte receipt produced by the Polygon zkEVM cache layer is the same primitive reused by the Bitcoin and Solana cache layers. A zkEVM proof, verified once on Cachee, is distributed as a portable computation receipt that a Bitcoin bridge, a Solana program, and any rollup with a Polygon dependency independently verify — without re-running the STARK, eliminating duplicated cross-chain proof verification.
This is what "cross-chain result reuse" actually means. Not a bridge token. Not a wrapped asset. The verification itself is the asset.
If you operate one of these and pay for proof verification compute repeatedly — Cachee turns that bill into a single attestation.
zk economics are dominated by two hidden costs: generating proofs (prover compute) and repeatedly verifying them (everyone downstream). The proof-generation cost is well understood. The repeated-verification cost is the invisible tax that compounds with every new consumer of the rollup.
Marginal cost of a new consumer collapses. Adding a new bridge, indexer, exchange, or DEX integration no longer means adding a new pass of STARK verification. The new consumer reads the existing attestation. L2 verification infrastructure stops scaling node fleets linearly with customer count.
Cross-system trust collapses to zero cost. Two systems that don't trust each other — a bridge and a rollup, an exchange and a DEX, an indexer and an explorer — agree on zkEVM state without either running prover infrastructure. Both verify the attestation; neither re-executes the proof.
The trust model shifts to post-quantum. Long-lived zk infrastructure built against Cachee inherits a 74-byte attestation that survives the EC → PQ migration. Settlement layers, restaking-backed prover markets, and regulatory-grade rollups design verification receipts that are never redone when the cryptographic ground shifts.
This is what we mean by zkEVM scaling infrastructure. Not bigger batches. Not faster provers. Verification that doesn't need to be repeated.
Pair the Polygon zkEVM cache layer with Bitcoin and Solana — one post-quantum attestation primitive, three live integrations, cross-chain by design.
