Blockchain’s First Fully Post-Quantum Transaction Just Settled on Mainnet. Here Is the Hash.

BitcoinWorld Blockchain’s First Fully Post-Quantum Transaction Just Settled on Mainnet. Here Is the Hash. On QoreChain mainnet (qorechain-vladi), a 1,000 QOR transfer to a wallet created in Keplr is the first mainnet transaction to settle on a fully post-quantum foundation: an ML-DSA-87 (Dilithium-5) signature on the transaction, ML-KEM-1024 as the chain’s key-encapsulation primitive, and SHAKE-256 as its live default hash, all finalized NIST standards. Here is why that is a first, and how any developer can verify it byte for byte. Rolle, Switzerland – On July 2nd 2026, a transfer of 1,000 QOR settled on QoreChain mainnet (qorechain-vladi) on a fully post-quantum cryptographic foundation. The claim is precise, and deliberately so: this is not merely a post-quantum signature, which several networks already have, but the first live mainnet transaction to settle on a foundation that is post-quantum across all three primitive classes at once, all finalized standards from the U.S. National Institute of Standards and Technology. The transaction itself carries an ML-DSA-87 (Dilithium-5, FIPS 204) signature and is recorded under the chain’s SHAKE-256 (FIPS 202) hash, and the chain’s key-encapsulation primitive is ML-KEM-1024 (FIPS 203). Classical fallback is disabled on the transaction path. The transaction is public, and every claim below is checkable on the explorer at explore.qore.network. For a technical audience, the phrase that matters is “full stack.” Post-quantum signatures have appeared on other networks. What has not shipped before, to the team’s knowledge, is a live mainnet transaction that settles on a foundation where the signature, the key-encapsulation primitive, and the hash function are all post-quantum and all drawn from the finalized NIST standards, produced from a standard self-custody wallet rather than a laboratory harness. The receiving wallet was created in Keplr, a wallet anyone can install. Why this is a first, and why it is not the others Being specific is what makes the claim defensible. Post-quantum work has been happening across the industry, and this milestone does not erase it. It clears a higher and narrower bar: one live mainnet where a settled transaction rests on all three finalized NIST post-quantum primitive classes together, a signature (ML-DSA, FIPS 204), key encapsulation (ML-KEM, FIPS 203), and a hash foundation (SHAKE-256, FIPS 202), at NIST Security Level 5, with classical fallback closed on the transaction path. To displace the claim, another chain has to show the same three, live, at once. Here is where the closest efforts stand, by their own public materials. Algorand executed a mainnet Falcon-signed transaction in November 2025 and pioneered Falcon-signed State Proofs in 2022, and deserves credit for both.
