Cachee is AI-powered distributed cache infrastructure for Bitcoin nodes, wallets, bridges, indexers, and exchanges. Evidence-backed outcome caching eliminates duplicated RPC fan-out, cuts UTXO state lookups, removes redundant merkle reconstruction, and accelerates signature verification. Downstream systems independently verify the cached result without re-running the verification and without trusting the cache operator. H33-74 attaches a 74-byte post-quantum evidence reference to each cached outcome; H33's cryptographic replay reconstructs the trust path. Cachee stores and serves across the industry's migration off elliptic curves.
The H33-74 evidence element — not Cachee — lets independent parties trust each cached outcome without trusting the cache operator. That single property converts blockchain verification from a per-node cost into a shared, portable asset — the foundation of distributed verification infrastructure.
— The category shift
Every Bitcoin participant — full nodes, light clients, SPV wallets, bridges, indexers, block explorers, exchanges, custodians, analytics platforms, settlement systems — performs the same verification work over and over. The same block header gets validated thousands of times. The same merkle path gets reconstructed for every SPV client. The same UTXO state gets re-queried millions of times per day across the network.
This is the design Bitcoin chose for trust minimization, and it works. But modern Bitcoin infrastructure has scaled the cost of that design to the point where verification is the bottleneck. RPC providers run massive node fleets just to answer the same questions repeatedly. Bridges replay block validation per relay. Indexers re-process the chain on every restart. Wallet sync still takes minutes because there's no portable, trustable answer that survives across sessions.
The waste is structural. It's not a Bitcoin-protocol problem — it's an infrastructure-layer problem that every chain inherits.
These are the operational line items that Bitcoin infrastructure teams pay for every day. Each one is a searchable pain point — and each one collapses from linear → constant with portable verification receipts.
getblock, gettxout, and getrawtransaction calls millions of times. Cachee distributes those answers as attested cache entries reusable across operators and consumers, with a post-quantum attestation as the trust anchor.A single cached result 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 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.
Most blockchain infrastructure still assumes elliptic-curve trust models — secp256k1 signatures, EC-based bridge proofs, EC-anchored attestations. The entire stack inherits a single hardness assumption that the cryptography community expects to break within the working lifetime of the infrastructure being built today.
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 verification receipts remain portable through the industry's migration to PQ cryptography. Infrastructure that ships against Cachee today doesn't need to redo its trust assumptions when quantum computers arrive — or when NIST tightens the standards, or when an EC-side vulnerability is disclosed.
For long-lived Bitcoin infrastructure — custodial systems, settlement layers, regulatory reporting, multi-decade time-locked vaults — post-quantum portability isn't a feature. It's the only honest design choice.
Three concrete surfaces where portable verification pays for itself immediately.
The pattern repeats anywhere Bitcoin state is read more often than it changes: SPV acceleration, UTXO caching, bridge verification, validator performance, light client performance, proof caching, blockchain indexing. Cachee compresses the verification cost from per-consumer to per-attestation — and the attestation is post-quantum, so the cost collapse survives the PQ migration.
Bitcoin doesn't live alone. Polygon zkEVM bridges read Bitcoin state. Solana programs settle against Bitcoin checkpoints. Rollups anchor to Bitcoin for finality. Every one of those systems pays the full Bitcoin 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 Bitcoin cache layer is the same primitive reused by the Polygon zkEVM and Solana cache layers. A Bitcoin block, verified once on Cachee, is distributed as a portable computation receipt that a Polygon bridge, a Solana program, and a Cosmos zone independently verify — without re-running Bitcoin validation, eliminating duplicated cross-chain compute.
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 verification compute repeatedly — Cachee turns that bill into a single attestation.
The economics of blockchain infrastructure are dominated by a single hidden line item: the cost of independently re-verifying state that has already been verified. When that cost moves from per-consumer to per-attestation, three things happen.
Marginal cost of a new consumer collapses. Adding a new wallet, bridge, indexer, or analytics integration no longer means adding a new full pass of verification. The new consumer reads the existing attestation. RPC providers stop scaling node fleets linearly with customer count.
Cross-system trust collapses to zero cost. Two systems that don't trust each other — a wallet and an exchange, a bridge and a rollup, an indexer and an explorer — agree on chain state without either operating Bitcoin infrastructure. Both verify the attestation; neither re-executes the verification.
The trust model shifts to post-quantum. Long-lived infrastructure built against Cachee inherits a 74-byte attestation that survives the EC → PQ migration. Custodial systems, settlement layers, and regulatory reporting design verification receipts that are never redone when the cryptographic ground shifts.
This is what we mean by Bitcoin scaling infrastructure. Not bigger blocks. Not faster nodes. Verification that doesn't need to be repeated.
Pair the Bitcoin cache layer with Polygon zkEVM and Solana — one post-quantum attestation primitive, three live integrations, cross-chain by design.
