Abstract: The current invention is connected with the system and the method of post-quantum cryptography through quantum-resistant blockchain transactions. Elliptic-curve cryptography is used in traditional blockchain, which is vulnerable to quantum cryptographic algorithms such as Shor. To address this threat, this invention introduces a blockchain design to modifications or to strengthen wallets, transactions, consensus mechanisms, and smart contracts against quantum attacker adversarial software exploitations, through the addition of PQC algorithms, including Dilithium, Falcon and SPHINCS +. It builds upon a variant of a hybrid dual-signature-based approach where antique Signatures and PQC Signatures across a migration period are facilitated with the objective of enabling interoperability during a following invulnerable backward implementation. PQC validation Smart contracts expressly accept quantum-resistant authentication (this is achievable with or without privacy-preserving data encryption), so user applications and DAOs can place quantum-resistant authentication on-chain. It is based on compression/aggregation schemes of signatures like Merkle schemes to keep the storage and executions demands of large PQC signatures down. The invention offers end-to-end protection implemented at all layers of the blockchain to deliver a future-proof framework with your cryptocurrency wallet utility, enterprise blockchain, government identity systems, decentralized finance (DeFi), and central bank digital currencies (CBDCs) implementation.
