Rolle, Switze la d, July 04, 2026 (GLOBE NEWSWIRE) — O July 2 d 2026, a t a sfe of 1,000 QOR settled o Qo eChai mai et (qo echai -vladi) o a fully post-qua tum c yptog aphic fou datio . The claim is p ecise, a d delibe ately so: this is ot me ely a post-qua tum sig atu e, which seve al etwo ks al eady have, but the fi st live mai et t a sactio to settle o a fou datio that is post-qua tum ac oss all th ee p imitive classes at o ce, all fi alized sta da ds f om the U.S. Natio al I stitute of Sta da ds a d Tech ology. The t a sactio itself ca ies a ML-DSA-87 (Dilithium-5, FIPS 204) sig atu e a d is eco ded u de the chai ‘s SHAKE-256 (FIPS 202) hash, a d the chai ‘s key-e capsulatio p imitive is ML-KEM-1024 (FIPS 203). Classical fallback is disabled o the t a sactio path. The t a sactio is public, a d eve y claim below is checkable o the explo e at explo e.qo e. etwo k.
Fo a tech ical audie ce, the ph ase that matte s is “full stack.” Post-qua tum sig atu es have appea ed o othe etwo ks. What has ot shipped befo e, to the team’s k owledge, is a live mai et t a sactio that settles o a fou datio whe e the sig atu e, the key-e capsulatio p imitive, a d the hash fu ctio a e all post-qua tum a d all d aw f om the fi alized NIST sta da ds, p oduced f om a sta da d self-custody wallet athe tha a labo ato y ha ess. The eceivi g wallet was c eated i Kepl , a wallet a yo e ca i stall.
Bei g specific is what makes the claim defe sible. Post-qua tum wo k has bee happe i g ac oss the i dust y, a d this milesto e does ot e ase it. It clea s a highe a d a owe ba : o e live mai et whe e a settled t a sactio ests o all th ee fi alized NIST post-qua tum p imitive classes togethe , a sig atu e (ML-DSA, FIPS 204), key e capsulatio (ML-KEM, FIPS 203), a d a hash fou datio (SHAKE-256, FIPS 202), at NIST Secu ity Level 5, with classical fallback closed o the t a sactio path. To displace the claim, a othe chai has to show the same th ee, live, at o ce. He e is whe e the closest effo ts sta d, by thei ow public mate ials.
Algo a d executed a mai et Falco -sig ed t a sactio i Novembe 2025 a d pio ee ed Falco -sig ed State P oofs i 2022, a d dese ves c edit fo both. Falco , howeve , is a diffe e t scheme that NIST is sta da dizi g sepa ately as FN-DSA (FIPS 206), ot ML-DSA (FIPS 204), a d Algo a d’s ow mate ials ote that its co se sus a d built-i t a sactio s still use Ed25519 a d that this does ot p ovide full qua tum secu ity at p ese t. The e is o ML-KEM key e capsulatio a d o SHAKE-256 hash fou datio . That is a post-qua tum sig atu e, ot a post-qua tum stack.
QRL has authe ticated t a sactio s with hash-based XMSS o e-time sig atu es si ce lau ch, which is ge ui e a d ea ly post-qua tum histo y. It is also a si gle hash-based sig atu e family: o ML-DSA lattice sig atu e, o ML-KEM key e capsulatio , a d ot the FIPS 203, 204, a d 202 combi atio .
BNB Chai has a ou ced mig atio wo k movi g t a sactio sig atu es a d co se sus votes to ML-DSA-44 with pqSTARK agg egatio . By its ow mig atio table, the P2P ha dshake move to ML-KEM a d the KZG commitme t eplaceme t a e still pe di g, so the key-e capsulatio leg is ot yet live, a d ML-DSA-44 sits at NIST Level 2 agai st Qo eChai ‘s Level 5 ML-DSA-87 a d ML-KEM-1024. That is post-qua tum mig atio i p og ess, ot a settled t a sactio o a completed th ee-p imitive fou datio .
Abelia has u lattice-based sig atu es a d a key-e capsulatio mecha ism o mai et si ce 2022, usi g p imitives i spi ed by CRYSTALS-Dilithium a d Kybe athe tha the fi alized NIST FIPS 203 a d 204 algo ithms. Qo eChai ‘s disti ctio is the fi alized NIST sta da ds specifically.
The commo th ead is simple to check: fi alized NIST sta da ds, all th ee p imitive classes togethe as the live fou datio , Secu ity Level 5, a d a publicly ve ifiable settled t a sactio o a amed mai et. Each of the effo ts above is missi g at least o e of those, which is exactly why Qo eChai f ames this as the fi st fully post-qua tum t a sactio stack athe tha the fi st post-qua tum t a sactio .
Qo eChai e fo ces post-qua tum c yptog aphy by default o its Cosmos t a sactio path. The x/pqc module u s with hyb id_sig atu e_mode set to equi ed a d allow_classical_fallback set to false. I p actice, eve y cosmos-path t a sactio must ca y both a classical secp256k1 sig atu e a d a Dilithium-5 sig atu e; a classical-o ly t a sactio f om a PQC accou t is ejected. The o ly bootst ap exemptio s a e ge esis ge txs at height 0 a d the PQC key- egist atio messages themselves, so a accou t ca egiste its fi st key. This 1,000 QOR t a sfe is a cosmos-path ba k t a sactio , which is why it ca ies the hyb id post-qua tum sig atu e.
A desig choice wo th stati g plai ly, because it is i te tio al a d built fo develope s athe tha a gap: the e fo ced hyb id post-qua tum equi eme t cu e tly applies to the Cosmos t a sactio path, while the EVM la e authe ticates o a sepa ate eth_secp256k1 path (the Qo eChai EVM E gi e path). Keepi g the EVM path byte-compatible with the Ethe eum sta da d is the poi t. It mea s existi g wallets, lib a ies, a d tooli g wo k o Qo eChai u cha ged, which lowe s the ba ie fo Solidity teams a d makes it fa easie to co ect Qo eChai to the wide EVM ecosystem a d to othe chai s. Compatibility is what lets builde s a ive without a ew ite. Post-qua tum sig i g fo the EVM path is al eady developed, a d sta da dizi g it ac oss the EVM la e is the ext step, so builde s keep that compatibility a d gai the same qua tum-safe p otectio . Today, the e fo ced e d-to-e d gua a tee lives o the Cosmos path, which is whe e this 1,000 QOR t a sfe settled.
The post-qua tum sig atu e t avels as a t a sactio exte sio with the type URL /qo echai .pqc.v1.PQCHyb idSig atu e. Fo Dilithium-5, that is a 4,627-byte sig atu e bou d to a 2,592-byte public key, both at NIST Secu ity Level 5, the highest sta da dized catego y. Ve ificatio is dete mi istic a d ep oducible ac oss eve y validato , which is what makes the esult auditable athe tha a ecdotal.

Develope s who wa t to ep oduce the p imitives ca use the ope -sou ce qo echai -pqc lib a y, which exposes ML-DSA, ML-KEM, a d SHAKE-256 th ough o e byte-compatible API ac oss six la guages (JavaSc ipt a d TypeSc ipt, Rust, Go, C, Pytho , a d Java), o attach a cosig atu e di ectly with qo echai d tx pqc cosig .
Post-qua tum p imitives a e big. A Dilithium-5 sig atu e is 4,627 bytes whe e a ECDSA sig atu e is o the o de of 64 to 72, a d eve y cosmos-path t a sactio o Qo eChai ca ies o e, alo gside ML-KEM key mate ial a d SHAKE-256 hashi g. Co ve tio al wisdom says that has to be slow.
It is ot, a d the umbe s a e measu ed athe tha modeled. O a six-validato dev et i Ju e 2026, Dilithium-5 ve ificatio took about 53 mic oseco ds a d sig i g about 110 mic oseco ds, so the post-qua tum check adds o the o de of 53 mic oseco ds to a t a sactio .

Put plai ly, the post-qua tum laye is measu ed i mic oseco ds while blocks a e measu ed i seco ds. It does ot egiste .
Th oughput is bou ded by block space, ot by c yptog aphy. The tested block pa amete s leave head oom o the o de of 64,000 t a sactio s pe seco d at typical t a sactio sizes, a d a multi-accou t test placed 40 co cu e t t a sactio s i to a si gle block with o co te tio . That is the takeaway fo a develope : Qo eChai puts a full post-qua tum sig atu e o eve y cosmos-path t a sactio a d still u s i the pe fo ma ce class of the fastest mode Laye 1s, because the qua tum-safe p imitives cost mic oseco ds, ot seco ds.
