Decentralized post-quantum threshold signatures and zk-STARK proofs that protect bridges, treasuries, validators, and DAO governance against the inevitable quantum break, without changing your existing stack.
// rust · qpl-sdk let sig = client.signing().sign(b"message").await?;
Quantum doesn't break the consensus. It breaks the keys that run on top of it. And every protocol team has a 7-9 year window to migrate before the math stops working.
Every cross-chain bridge depends on ECDSA multisigs to control locked collateral. When CRQCs arrive, those keys are recoverable from public signatures. Every bridge drains in parallel. There is no incident response for "the math broke."
DAO treasuries and protocol multisigs use the same ECDSA primitives that secure Bitcoin. The same day a CRQC ships, every onchain treasury that has ever signed a transaction is recoverable by anyone with the published pubkey.
PoS validator signing keys, MEV-relay keys, oracle attestation keys: all classical. A quantum attacker doesn’t need to break the chain. They just steal the keys signing on it.
Nation-state adversaries are archiving today’s encrypted mempool data, signed messages, and key-exchange handshakes for future decryption. Every transaction you sign today is a hostage that becomes recoverable on Q-day.
QPL is not a blockchain. It's the layer that protocols on every chain call when they need a signature or a proof that survives Q-day.
N-of-M quantum-resistant threshold signing. No single operator holds the complete key. 3-of-5 quorum, HSM-wrapped shards, zero-knowledge key shares.
Zero-knowledge proofs with no trusted setup and quantum-resistant hash assumptions. High128 security level. Verifiable on-chain.
Operators serve Ed25519, ECDSA-P256, or ML-DSA-65 per request via dynamic algorithm negotiation. Clean migration as FIPS 204 firmware ships to HSMs.
QPL only works when protocols integrate, operators run the infrastructure, and backers fund the public good. Pick your side.
Bridges, DEXs, lending markets, oracles, DAOs. Bolt QPL onto your existing custody and governance. No consensus changes, no hard forks, no enterprise contracts. Pay per signature, per proof.
Independent service providers operate the quantum-resistant signing network. 15 Genesis seats. HSM-backed, threshold-secured, per-operation fee revenue for compute performed.
Public raise live on Futard.io. Solana’s permissionless launchpad with onchain spending limits and futarchy governance. Support the network the post-quantum DeFi stack will run on.
Protocol sends a signing or proving request via SDK. Specifies algorithm preference, urgency tier, and quorum size.
client.signing().sign(payload).await?;
Deterministic coordinator selection via consistent hashing. Coordinator assembles a 3-of-5 quorum, routes partial signing tasks, and aggregates partial signatures.
coordinator.assemble_quorum(t=3, n=5);
Combined signature returned to protocol. Verifiable on-chain. Quantum-resistant. Completed in ~200ms off-chain latency.
verify_on_chain(sig, pubkey);
Per-operation pricing means no enterprise contracts, no minimums, no surprises. Drag the dials and read the number. That’s the number.
* Estimates only. Actual cost is the on-chain sum of per-operation fees you consume. No subscription, no commitment, no enterprise license.
Rust crate, gRPC API, Solana-native. Import and start signing.
Serves Ethereum, Solana, Cosmos, Move-based chains. Quantum risk is universal.
Read the docs, import the SDK, integrate. The code sells itself.
Per-operation fee. No enterprise tiers. No negotiated contracts.
ML-DSA-65 (FIPS 204), ML-KEM-1024 (FIPS 203). Not experimental.
Threshold cryptography has bounded coordination cost. The network is intentionally constrained to 15 operators through Cohort 01. After that, the protocol opens permissionlessly. Operators are independent service providers running quantum-resistant infrastructure and earning service fees for computational work performed.
5 of 15 Cohort 01 seats are reserved for qualifying Futard.io holders. Hold the token, meet the operator requirements, get application priority. Remaining 10 seats are open to anyone who qualifies.
* Operator fees are compensation for computational services rendered. Revenue varies with network demand. Staking SOL is a security deposit for network access, not an investment. Futard.io holder priority is application-stage routing only. It does not waive operator requirements, KYB, or HSM attestation. QPL does not guarantee earnings.
Every assumption is documented. Every primitive is standardized. Every operator is constrained by an HSM boundary and an on-chain stake.

QPL is the only open-source, quantum-proof, chain-agnostic signing and proving infrastructure with transparent per-operation pricing.
Genesis operators onboard. Public testnet open.
3rd-party security audits. Bug bounty live.
STARK proof system formally verified.
Public availability. Open operator registration.
QPL ships pseudonymously by design. In quantum-resistant crypto, team bios don't prove the math. What does: open source, published audits, formal threat models, and key material that operators physically cannot exfiltrate.
* If you are a researcher, cryptographer, or auditor who wants to review the protocol, the repo is open. Issues and security disclosures live on GitHub.
One email per release. Operator-cohort openings, SDK updates, audit publications, and Futard raise milestones. No noise.
