QoreChain announced that it has completed what it described as the first blockchain transaction on a live public mainnet to be protected end-to-end using all three post-quantum cryptographic algorithms standardized by the U.S. National Institute of Standards and Technology (NIST). The milestone involved a transaction secured throughout its entire cryptographic process with ML-DSA-87 for digital signatures, ML-KEM-1024 for key encapsulation, and SHAKE-256 for hashing, rather than relying on post-quantum protection for only a single component.
According to the company, the transaction involved the transfer of 1,000 QOR tokens on July 2, 2026, to a wallet created using the widely adopted Keplr wallet. It added that the transaction was completed on its public mainnet and remains publicly accessible through the blockchain explorer, allowing independent verification by anyone.
QoreChain, which describes itself as a quantum-safe and AI-native Layer 1 blockchain, said the achievement marked the first instance of a blockchain transaction being secured from end to end with all three NIST-standardized post-quantum cryptographic algorithms on a live public network.
Complete Cryptographic Protection
The company stated that many blockchain projects promoting quantum-resistant capabilities typically replace only one cryptographic component, most often transaction signatures, while continuing to rely on conventional cryptography for other parts of the protocol. According to QoreChain, such an approach leaves portions of the system potentially vulnerable to future quantum computing attacks.
By contrast, the company said its latest transaction incorporated post-quantum cryptography across every stage of the cryptographic process. It explained that the transaction employed ML-DSA-87, standardized under FIPS 204 and based on Dilithium-5, for digital signatures, ML-KEM-1024, standardized under FIPS 203 and derived from Kyber, for key encapsulation, and SHAKE-256 for hashing. All three algorithms have been standardized by NIST.
Founder and Chief Technology Officer Liviu Epure said the company’s long-standing position had often been viewed as premature. He stated that the latest transaction demonstrated that the discussion had moved beyond theory because every stage of the cryptographic process—including signing, key exchange, and hashing—was protected using post-quantum algorithms. He also noted that the receiving wallet was created using the Keplr wallet, enabling users to access the technology through an application already available to the public.
Today, QoreChain did what no blockchain has done before.

Preparing for the Quantum Computing Era
President and Chief Executive Officer Tilak Patel said the company was focused less on being first than on ensuring readiness for the coming transition to quantum computing. He explained that financial institutions and other organizations requiring strong security standards would need infrastructure that follows recognized standards rather than experimental technologies. He added that the transaction demonstrated that standardized, live, and independently verifiable post-quantum security could now be implemented on a public blockchain.
The company linked the announcement to growing concerns surrounding the Harvest Now, Decrypt Later strategy, under which attackers collect encrypted information today with the expectation of decrypting it once sufficiently powerful quantum computers become available. QoreChain argued that because blockchain records remain permanently accessible, networks that do not implement post-quantum cryptography from the outset could face the risk of historical data being exposed in the future. The company said migrating to quantum-resistant systems later would secure only newly created data rather than information already stored on the blockchain.
Built With Existing User Tools
QoreChain emphasized that the transaction was completed using mainstream software instead of specialized laboratory infrastructure. The company said the recipient wallet was generated through the Keplr self-custody wallet, demonstrating that users would not need to abandon widely used tools to benefit from post-quantum security.
Epure said the objective had been to make the technology practical rather than confining it to controlled testing environments. He encouraged cryptographers, engineers, and researchers to examine the publicly available transaction, stating that its open availability was intended to enable independent technical verification.
The company added that its public mainnet is operational, its blockchain explorer is publicly accessible, and its developer documentation is currently available in ten languages.
