Tracking BitCoin "Q-Day".

Researcher cracks 15-bit elliptic curve key, aka an Elliptic Curve Cryptography (ECC) Key using public quantum hardware and is awarded the “Q-Day Prize bounty" of 1 BTC.

BitCoin and Ethereum utilize ECC - the larger 256 bit key - specifically the secp256k1 curve, for securing wallets and transactions. https://decrypt.co/365444/bitcoin-q-day-draws-nearer-quantum-researcher-breaks-simplified-key #Bitcoin #Cryptography #Ethereum #Crypto #CryptoCurrencies #Encryption #Security #ECC #EllipticCurve #QDay #DigitalSignature #BlockChain #QuantumComputing #Quantum #BTC

@decrypt.co Still waiting for results (successful submissions) from #QDay price (Project 11). Let us see if anyone reported some #ECC key break of any size on a real quantum platform up and running today. The coming weeks will show how big the "quantum threat" to Bitcoin really is.

양자컴퓨터가 타원곡선 암호를 깨는 데 필요한 큐비트 수를 크게 줄였다는 새로운 연구가 소개됐다. 이 연구는 HTTPS 연결, 디지털 서명, 암호화폐 지갑을 보호하는 핵심 암호체계의 안전성에 대한 우려를 키우며, 양자암호/보안 분야에 중요한 시사점을 준다.

A new research work dramatically reduces the amount of qubits to break elliptic curve ciphers on a hypothetical quantum computer. Elliptic curve crypto is the math protecting most HTTPS connections, digital signatures, and cryptocurrency wallets. Shor's quantum algorithm can

UWAGA! AliExpress wspiera oszustwa "Bait & Switch". Sprzedawca Shop1104057082 podaje fake tracking i nie wysyła towaru, choć oferta wciąż wisi. AE ignoruje dowody i po 1,5 m-ca wymusza niechciany zwrot pieniędzy. Totalna fikcja ochrony kupujących! Case: 2053807544521661 #AliExpress #Oszustwo #ECC

WARNING!!! AliExpress supports "Bait & Switch" fraud. Seller Shop1104057082 uses fake tracking & refuses to ship, but keeps the listing active. AE forces unwanted refund after 1.5 months, ignoring evidence. Total failure of protection! Case: 2053807544521661 #AliExpress #Scam #ECC

Called it.

In Nov I wrote that ECC was the easier quantum target: postquantum.com/post-quantum/shor-rsa-ecc-diffie-hellman/

In March I argued Bitcoin's quantum risk was underestimated because everyone used RSA benchmarks: postquantum.com/post-quantum/bitcoin-quantum-risk-closer-ecc/

EUROCRYPT 2026 just confirmed both.

Chevignard, Fouque & Schrottenloher halved ECDLP qubit counts:

P-256: 2,124 → 1,193 (42% less than RSA-3072!)

P-224: 1,098 (21.5% less than RSA-2048)

A New Algorithm Shrinks the Quantum Attack Surface for ECC

15 Mar 2026 - When Clémence Chevignard, Pierre-Alain Fouque, and André Schrottenloher submitted their latest paper to EUROCRYPT 2026, they already had a track record that the cryptographic community was watching closely. In 2024, the same team at INRIA Rennes had published a method that slashed the qubit requirements for quantum factoring of RSA integers - work that Craig Gidney at Google Quantum AI subsequently used as a foundation to bring the estimated physical qubit cost of breaking RSA-2048 from 20 million down to under one million. That result sent tremors through every risk committee tracking quantum timelines. Now the

Quantum Decryption of RSA Is Much Closer Than Expected

The JVG algorithm factors RSA and ECC keys using fewer quantum resources than Shor’s algorithm, accelerating the time needed to break today’s public-key cryptography.
