Swiss-registered blockchain network QoreChain has recorded a transaction on its live public mainnet utilizing a complete, end-to-end post-quantum cryptography (PQC) stack. The transaction involved a transfer of 1,000 QOR executed on July 2, 2026, routing directly into a standard address generated via the open-source Keplr self-custody wallet. While individual decentralized protocols have previously implemented partial quantum-resistant signatures at the transaction edge, this network deployment marks a milestone by applying standardized post-quantum math across the protocol’s entire cryptographic path—covering signatures, key exchanges, and hash functions simultaneously.
[ QoreChain Full-Stack PQC Architecture ]
Signature Layer ──► ML-DSA-87 (FIPS 204 / Dilithium-5) Category 5 signature verification.
Encapsulation ──► ML-KEM-1024 (FIPS 203 / Kyber) quantum-safe asymmetric key exchange.
Hashing Framework ──► SHAKE-256 state functions replacing traditional elliptic-curve primitives.
The comprehensive layer-1 deployment directly targets the “Harvest Now, Decrypt Later” vulnerability, where external actors record encrypted block data and public key histories from distributed ledgers today to compromise them retroactively once fault-tolerant quantum computers become available. Running on the Cosmos SDK v0.53 framework, the production mainnet (qorechain-vladi, EVM Chain ID 9801) integrates National Institute of Standards and Technology (NIST) FIPS 203 and 204 compliant algorithms natively within its genesis state layer. Rather than applying temporary application-level patches, the network’s specialized engineering pairs hybrid secp256k1 + ML-DSA-87 signatures with an AI-optimized PRISM Consensus engine that executes deterministic, on-chain reinforcement learning inference to dynamically tune node parameters.
To support general-purpose web3 deployment, the protocol pairs its quantum resistance with a triple-VM runtime environment that natively executes EVM, CosmWasm, and SVM smart contracts on a single chain with native cross-VM messaging. For decentralized application development, the node architecture deploys sidecar containers running a dedicated anomaly detection and risk scoring engine (QCAI) alongside standard JSON-RPC, REST, and gRPC endpoints. Operated under the Swiss DLT Act by the QoreChain Association in Rolle, Switzerland, the platform features a deflationary utility token model where 30% of all gas fees are permanently burned. The organization holds a FINMA no-action letter classifying its native asset, QOR, as a utility token.
