Google says Willow chip advance cuts quantum error rate by about 40x

Google Quantum AI said in a paper published in Science that its "magic state cultivation" technique reduced the error rate by about 40 times on the company’s Willow processor, while reaching 99.99% fidelity for the resulting magic states. Magic states are single-use resources needed to run practical quantum programs, and earlier estimates had suggested that preparing them could account for as much as 95% of a quantum computer’s total compute capacity. Google said the work turns one of quantum computing’s most promising theoretical methods into something that can be used on chip in practice. According to the Techub summary, citing Decrypt, the advance is also one of the key pieces behind Google’s 2025 projection that the number of noisy qubits required to break RSA-2048 encryption could fall below one million. The report added that lower construction costs for quantum computers could speed up applications in drug design and new materials research, while also carrying implications for the cryptography used to secure bank logins and Bitcoin wallets.

EU MiCA review weighs certification requirement for non-custodial Bitcoin wallet software

The European Union is reviewing its Markets in Crypto-Assets framework, and the consultation process has raised the possibility that developers of non-custodial Bitcoin wallets could be required to obtain certification before offering software to the public. The point surfaced in a post on X cited by Bitcoin News. At the same time, the European Securities and Markets Authority, or ESMA, said open-source development, self-custody, automated smart contracts and permissionless infrastructure should not automatically be treated as regulated intermediaries. ESMA also proposed creating a new regulated service category for crypto-asset service providers that give clients access to decentralized protocols. No current rules have been changed at this stage. The European Commission will review the feedback it receives and, under Article 140 of MiCA, submit a review report by June 30, 2027.

Samourai Wallet co-founder says he faces another prison transfer

Samourai Wallet co-founder Keonne Rodriguez said in a social media post that he and 70 other inmates are facing another prison transfer after his treatment program was discontinued. Rodriguez said his previous transfer took 30 days. Samourai Wallet is a privacy-focused Bitcoin wallet. Its two co-founders, Rodriguez and William Lonergan Hill, were previously charged by the U.S. Department of Justice with allegedly operating an unlicensed money-transmitting business and conspiracy to commit money laundering. The update was cited by Techub, which referenced Cointelegraph.

Sparrow Wallet proof of concept shown running on a $40 handheld gaming device

Bitcoin News said in a post on X that @DesobedienteTec has released a working proof-of-concept version of Sparrow Wallet after previously porting SeedSigner to a $40 handheld gaming device. The update points to another example of bitcoin wallet software being adapted to low-cost consumer hardware. According to the post, the device includes two microSD card slots and supports a camera and a virtual keyboard. It also supports game emulators for Nintendo, SEGA, N64, PSP, and PS1. No additional technical details, release timeline, or broader deployment plans were disclosed in the source material. The report was cited by Odaily as a market analysis newsflash.

Electrum 4.8.2 fixes critical Lightning wallet backup issue and adds security hardening

Electrum has released version 4.8.2 with a set of security fixes and broader hardening for its Bitcoin wallet codebase, according to a post by Bitcoin News on X. The release incorporates findings reported by Bitcoin Red Team, Calle, l0rinc, haoxucu, and m0wer. A key fix addresses a critical backup issue affecting some Lightning wallets that used non-deterministic keys and anchor channels. In those cases, channel backups and full wallet backups could miss the keys required to move funds on-chain after requesting a remote force close. Impacted users will see a warning when starting Electrum and are advised to export a new backup, as older backups cannot correctly recover funds in that scenario. The update also tightens Lightning HTLC validation, rejects malformed xpub/xprv keys that may previously have been accepted, expands security hardening across the codebase, and prevents the Android QR code scanner from reading screenshots. The release is Electrum’s third security-focused update since July, following versions 4.8.0 and 4.8.1.

Alby Hub discloses severe cross-version flaw, confirms one affected user

Bitcoin wallet provider Alby said a severe vulnerability affected Alby Hub versions v1.7.0 through v1.18.5, covering releases published before August 2025. According to the team, if a Hub instance was reachable from the public internet, an attacker could access the management API, gain unauthorized access, and move funds out of the wallet. Alby said v1.19.0 and later are not affected, noting that v1.19.0 was released on Aug. 29, 2025. The company has confirmed that one user was impacted. For users running affected versions, Alby urged immediate action: restrict public internet access to the management interface and upgrade to the latest release, v1.24.0. It also said that users whose management interface had previously been exposed publicly should change their unlock password after upgrading. Even users on unaffected versions were advised to move to v1.24.0 to receive additional security improvements. Alby added that it plans to publish full details later under a responsible disclosure process.

Xverse Wallet Launches Joint Bitcoin Staking with sBTC/STX Pairs for PoX-5 Lock-Up

Xverse, a bitcoin wallet, has announced a new joint bitcoin staking service that allows users to pair their sBTC tokens with STX tokens and participate in the PoX-5 lock-up cycle on the Stacks network. The key feature is that during the staking period, the bitcoin remains on the Bitcoin mainnet and is fully controlled by the user, without any need for cross-chain bridging or wrapping. To use this service, users must upgrade to Xverse v2.9. Registration is open until September 9, or until the quota is filled. Staking rewards are expected to start being distributed on September 10, corresponding to Bitcoin block 966350 and Stacks epoch 143. Several institutions have joined as anchor participants, including UTXO (a subsidiary of Nakamoto Inc.), HashKey Cloud, and 21shares. Previously, Xverse had managed approximately 152 million STX in non-custodial staking.

Coldcard attack tied to seed-generation flaw, Coinkite urges firmware upgrade

Techub News said Coinkite, the developer behind the Bitcoin wallet Coldcard, shared new details on Aug. 20 about an asset outflow disclosed on July 30, 2026, and strongly advised users of the Mk4, Mk5 and Q models to upgrade their firmware immediately. Coinkite said the attack stemmed from a seed-generation vulnerability and that law enforcement is still investigating. Galaxy Research data put total losses at more than $110 million, making it the third-largest crypto theft of 2026. Coinkite also said the new firmware cannot make already compromised seeds safe, and users need to move funds to wallets created with new seeds.
