Shor's algorithm reduces the security of ECDSA-256, the signature scheme underpinning the majority of production blockchains, from approximately $2^{128}$ classical operations to $O(2^{24})$ quantum operations, rendering it categorically broken in the post-quantum era. The "Harvest Now, Decrypt Later" attack vector compounds this risk: adversaries collecting signed transactions today can retroactively extract private keys once quantum hardware matures, exposing all assets whose public keys have been revealed on-chain. This paper presents QoreChain, a Layer~1 blockchain platform designed from first principles to operate in a post-quantum world. QoreChain integrates three foundational capabilities into a single protocol stack: (1)~full-stack post-quantum cryptography implementing NIST-standardised algorithms (ML-DSA-87 per FIPS~204, ML-KEM-1024 per FIPS~203, SLH-DSA per FIPS~205, and SHAKE-256) at FIPS Security Level~5 across every protocol layer, from transaction signing and consensus messaging to cross-chain bridge attestations; (2)~an AI-native intelligence layer (QCAI) that applies reinforcement learning to consensus parameter optimisation, graph neural networks to anomaly detection, and multi-objective optimisation to transaction routing; and (3)~a triple virtual machine execution environment supporting EVM, CosmWasm, and SVM within a unified state model with atomic cross-VM call semantics and full rollback guarantees. The consensus mechanism, Combined Proof of Stake (CPoS), merges Reputation PoS, Delegated PoS, and classical PoS with BFT finality. A five-way fee distribution (37\% validators, 30\% burned, 20\% treasury, 10\% stakers, 3\% light nodes) aligns incentives across all participant classes. Governance employs Quadratic Delegation with Reputation Weighting (QDRW), for which we present formal game-theoretic analysis demonstrating bounded resistance to plutocratic capture (voting power scales sub-linearly with stake) and flash-loan manipulation (reputation updates lag delegation by one block finality cycle). Cross-chain interoperability is provided by the QoreChain Bridge (QCB), connecting directly to 25 Layer~1 blockchains with over 120 additional networks reachable via IBC. All bridge operations are secured by ML-DSA-87 multi-attestation with QCAI anomaly detection and circuit breaker mechanisms. A multi-layer scaling architecture incorporating sidechains, paychains, and a Rollup Development Kit (RDK) enables horizontal throughput expansion while inheriting the main chain's quantum-safe settlement guarantees. The QOR token has a fixed supply of 4,500,000,000 with epoch-based emissions following a halving schedule. The architecture is designed for 5,000+ transactions per second with sub-second finality; multi-node testnet benchmarks are pending. QoreChain Association is incorporated under the Swiss DLT Act (CHE-484.963.998, Rolle) with formal FINMA utility token classification (January 2026). Testnet is operational (chain ID: \texttt{qorechain-diana}) with 47 genesis modules. Mainnet launch is targeted for Q4~2026. The full specification spans 16 chapters and 351 pages, presenting 530 formal equations, 78 data tables, and 9 architectural diagrams covering cryptographic foundations, AI integration, smart contract execution, consensus, tokenomics, governance, interoperability, and regulatory compliance.
