Odaily News: Researcher Robin Linus has released the Bitcoin Poker protocol, expanding the unfinished poker interface that Satoshi Nakamoto left in Bitcoin's early code in 2008 into a runnable solution. The protocol supports two players in Texas Hold'em without a dealer, using Bitcoin's existing rules to handle gameplay and fund settlement.Bitcoin Poker generates card faces through secret information jointly provided by both parties, generating only the 9 cards needed per hand, and uses cryptographic commitments and zero-knowledge proofs to maintain fair dealing. The protocol can check for duplicate cards, and the probability of a randomly generated hand passing the check is approximately 48%, requiring an average of 2.08 attempts.The protocol pre-builds a transaction tree for possible game outcomes, with a reference configuration containing 56,132 logical nodes and approximately 8.4 MB of preparation data. Normal gameplay occurs off-chain, with transactions used only to handle disputes when cooperation breaks down.If one party refuses to continue, a timeout mechanism can settle the committed pot after a specified delay and return the departing party's unused balance, but cannot force players to reveal their cards. The design requires no modifications to Bitcoin's consensus rules, supports only two participants, and still requires independent security review. (Bitcoin.com News)

Odaily News: Bitcoin News posted on X platform that U.S. federal prosecutors informed Judge Katherine Polk Failla that the U.S. Court of Appeals for the D.C. Circuit upheld the conviction of Bitcoin Fog founder Roman Sterlingov on September 25, supporting the trial of Tornado Cash defendant Roman Storm in New York. The appellate court determined that Washington, D.C. has trial jurisdiction, reasoning that law enforcement officers had deposited approximately $250 worth of Bitcoin into Bitcoin Fog from Washington, D.C. Prosecutors argued that since user Shakeeb Ahmed accessed Tornado Cash from his apartment in Manhattan, the same logic applies. Roman Storm released this letter and noted that FinCEN withdrew its 2023 mixer reporting requirement on the same day, citing concerns that the proposal could suppress legitimate activity.
Odaily News: As the crypto industry discusses whether users need to enter "bunker mode" before AI or quantum computing technologies expose wallet private keys, custody institutions face a more complex challenge: how to upgrade key management, approval, and audit systems before an emergency migration occurs.Project Eleven CEO Alex Pruden stated that institutions have already begun preparing for post-quantum migration outside of blockchain, and different blockchains may adopt different quantum-resistant signature schemes and migration paths in the future. Institutions holding multiple types of assets will face the challenge of simultaneously adapting to multiple cryptographic systems.Quantus co-founder and CEO Christopher Smith stated that AI is accelerating the development of quantum hardware and software, and the tail risk of quantum attacks should be incorporated into portfolio decisions — this is an institutional fiduciary duty.Currently, the timeline for quantum computers to crack Bitcoin and Ethereum's existing public-key cryptographic systems remains uncertain, but the industry is gradually viewing the coming years as a window for establishing migration plans, rather than waiting for an attack to occur before responding reactively.

HM Revenue & Customs (HMRC) is pushing to expand its investigation powers over crypto asset information, proposing to allow tax authorities to directly obtain customer data from crypto asset service providers and to update rules for inspecting software and electronic records. UK crypto tax software company Recap has warned that the proposed regulations' definition of service providers is too broad and could encompass non-custodial wallet software, blockchain explorers, hardware wallet manufacturers, and tax software providers. Since Bitcoin transaction records are publicly transparent, once investors' names, addresses, and tax identities are linked to on-chain wallet addresses, their long-term asset activity records could be exposed, increasing the risk of data leaks, extortion, and physical attacks.
Odaily reports: Bitcoin News posted on X platform that Lightspark has released a dotMoney prototype, allowing users to send test funds by sharing links, .money files, or directly between nearby iPhones. The files can be sent via AirDrop, messaging apps, or stored on a USB drive; the underlying funds are transferred between wallets via Spark. Each file can only be claimed once, and copying or forwarding will not generate duplicate funds. The sender can also cancel unclaimed payments. Currently, the prototype uses test funds with no monetary value, and Lightspark is also testing bank, Cash App, and Lightning withdrawal functionality through Grid.

Based on Monday's price of $85,179, these BTC are worth approximately $141 billion. Some of this is held on corporate balance sheets, while the rest backs ETF issuance and redemption shares.
Odaily Report: Blockchain platform Solana has launched x402 batch payment functionality through PayAI Network and BlockRunAI, enabling AI agents to initiate multiple USDC payments and settle them all through a single on-chain transaction.BlockRunAI has already applied this technology to its AI model routing service. The company states that by consolidating multiple model calls into a single USDC settlement, it can save over $20,000 per month in network fees and reduce latency by approximately 10x; its service provides access to over 113 AI models through a single endpoint.Solana development organization Anza stated that the upgrade to ultimately reduce Solana's block time to 200 milliseconds is expected to go live around 15:00 UTC on October 9, having previously been gradually reduced from 400 milliseconds to 350, 300, and 250 milliseconds.

According to Decrypt, Europol released a report on Wednesday stating that cryptocurrency wallets are the primary exposure points for quantum computing threats. Attackers can derive private keys from publicly exposed on-chain public keys and transfer assets, while underlying hash functions are largely quantum-resistant. The report notes that approximately 30.2% of BTC (6.04 million coins) public keys have already been exposed on-chain, recommending a phased industry transition to post-quantum cryptography, and calling for proactive preventive migration of related assets prior to an attack.
Odaily reports: Europol released two reports on Wednesday, urging organizations, policymakers, and the cryptocurrency industry to immediately prepare for the threat of quantum computing. Its European Cybercrime Centre noted that cryptocurrency wallet keys are the primary exposure point for quantum attacks, while the hash functions used to secure blockchains currently remain largely quantum-resistant.The reports state that a sufficiently capable quantum computer could derive private keys from exposed public keys, enabling attackers to transfer assets without authorization. Wallets whose public keys have already been exposed on-chain cannot be protected retroactively; holders need to migrate their assets to new wallets before an attack occurs.Glassnode estimated in May that 6.04 million BTC, representing 30.2% of the issued supply, have exposed public keys. The reports note that NIST-standardized post-quantum signatures are 10 to 120 times larger than the ECDSA signatures currently used by Bitcoin, and migrating all Bitcoin unspent transaction outputs would require at least 76 cumulative days of downtime.A second report published by Europol points out that commonly used protocols such as TLS, SSH, and OpenPGP face "harvest now, decrypt later" risks, but there is currently no clear evidence that this approach has been exploited at scale. The report argues that for payments, immediate interception within the brief window before transaction confirmation poses a more direct quantum risk than post-hoc decryption. (Decrypt)

Odaily reports: The U.S. Department of Justice (DOJ), in a filing submitted on Monday, cited the appellate ruling in the case of Roman Sterlingov, the operator of cryptocurrency mixer Bitcoin Fog, as supplementary grounds for opposing Tornado Cash developer Roman Storm's acquittal motion.U.S. prosecutors stated that the ruling supports their position that the Southern District of New York is the proper venue for the trial. Prosecutors argued that Shakeeb Ahmed used Tornado Cash in a Manhattan apartment, and that this activity is sufficient to establish venue for the money laundering and unlicensed money transmission conspiracy charges against Roman Storm.Judge Katherine Polk Failla heard arguments on Roman Storm's acquittal motion in April 2026 but has not yet issued a ruling. A jury in August 2025 convicted him of conspiracy to operate an unlicensed money transmitting business, but failed to reach a unanimous verdict on the money laundering and sanctions conspiracy charges, with a retrial tentatively scheduled for April 26, 2027.

Odaily News: Jan van Eck stated that approving more nuclear power projects could simultaneously boost AI and Bitcoin: on one hand by enhancing AI value, and on the other by easing Bitcoin selling pressure through providing cheaper energy to miners. Bipartisan support for nuclear energy in the U.S. is strong, with the goal of quadrupling nuclear power output within 25 years, as evidenced by the accelerated restart of the Three Mile Island nuclear reactor. Matthew Sigel, Head of Digital Assets Research at VanEck, stated that miners hold long-term power contracts and infrastructure, possessing undervalued optionality value; if miners shift toward AI contract revenue, their pressure to sell Bitcoin will correspondingly decrease.
