Bitcoinjs-lib, a library used to build Bitcoin applications, has patched two bugs that can make software understate the miner fee a valid transaction would pay if broadcast and accepted.The Oct. 26 security disclosures identify fixes in versions 5.2.2, 6.1.9 and 7.0.4 for the corresponding release lines.The affected format is a partially signed Bitcoin transaction (PSBT), and BIP 174 defines it as a way to pass transaction information and signatures between clients. Signing, combining signatures, finalizing inputs, and extracting the transaction are separate functions, even when one application performs several of them.The risk concerns applications that import these packages and trust…

BNY now supports custody of XRP and Ripple’s RLUSD stablecoin for eligible institutional clients, according to an Oct. 27 announcement from Ripple, giving institutions another way to hold and transfer the XRP Ledger’s native token.The service offers a banking route to safeguard the asset and manage its operations. BNY describes its platform as connecting custody with settlement, accounting and servicing.The announcement names no funded XRP custody client and discloses neither an XRP balance nor an incremental purchase. Moving tokens that clients already own to BNY would change their custodian without necessarily creating demand for more coins.BNY’s XRP custody supports transfers…

An attacker still acquired two governance seats on X100, a token project with a Senate-governed treasury, and approved a treasury transaction and repaid a flash loan in a single blockchain transaction on Oct. 24.At Arkadiko, a lending protocol where users borrow against vault collateral, a roughly five-day vote ended two days early, giving a malicious contract authority over vault assets. People bought voting tokens shortly before the decisive vote, and the proposal took effect when the ballot closed.The incidents expose different gaps between committing money, qualifying to vote, and executing an approved action. X100 tokens should be locked for a year,…

Polymarket’s five-minute Bitcoin contract sampled on Oct. 27 uses averaged opening and closing benchmarks, following an August reform that changed the incentive to move its settlement price.The current design requires a different risk assessment from the single-snapshot rule examined in earlier research.An estimate of about $8.2 million earned by 821 wallets in earlier pushed cycles belongs to that historical research. Guangzhe Wang’s newer study cites the finding from Dai and co-authors.Wang’s before-and-after results instead point to a subsiding Binance trading pattern in the first weeks after averaging. That gives the reform an empirical test, while keeping separate whether an observed…

Zcash faces competing proposals to scrap or extend developer subsidies as growing investor interest swells the privacy network’s funding reserves.The debate intensified after Zcash co-founder Sean Bowe proposed ending automatic payments to Zcash Community Grants (ZCG), arguing that the program already controls enough resources to finance years of development without additional subsidies.His proposal has drawn more aggressive demands from ZODL founder Josh Swihart, Gemini co-founder Tyler Winklevoss, and other ecosystem participants, while a rival plan would preserve reduced development funding until 2036.The disagreement comes as Zcash approaches its 10th anniversary on Oct. 28, with renewed institutional interest and rising private…

OpenAI says its AI system has refuted the Exponential Time Hypothesis, a longstanding assumption about how difficult certain logic problems are to solve. The Oct. 26 announcement has researchers organizing an independent examination. The disclosed result does not establish a practical attack on Bitcoin.ETH here means Exponential Time Hypothesis, rather than Ether. The subject is 3-SAT, a puzzle in which a computer must find true-or-false settings that satisfy a collection of logical rules. The hypothesis says solving these problems requires exponential time in the number of variables in the worst case.OpenAI says the result was verified in Lean, a proof…

Ripple said it secured final US approval for a national trust bank despite objections from traditional banking groups concerned about crypto firms entering regulated finance.The company announced on Oct. 26 that the Office of the Comptroller of the Currency (OCC) had granted final approval for Ripple National Trust Bank to manage RLUSD reserves, serve as collateral trustee and provide fiduciary digital asset custody. Ripple put RLUSD’s market capitalization at $2.5 billion in the announcement.Brad Garlinghouse, CEO of Ripple, said:“We’ve spent over a decade building regulated financial infrastructure that institutions can actually use at scale. A national trust charter gives us…

Lightning developers tightened BOLT11, the Lightning Network’s invoice standard, on Oct. 19 to require software to reject ambiguous payment-hash and payment-secret fields. The change follows a developer’s account of an attack that made completed Bitcoin withdrawals appear unpaid.The merged change targets software components reading the same signed payment request differently. A payment hash identifies the payment a component is tracking. Bitcoin Optech highlighted the rule change on Oct. 23.In a Sept. 10 statement on the proposal, developer Roasbeef reported a recent hack of a Telegram peer-to-peer bot that exploited libraries choosing different hashes: some took the first payment-hash field in…

By the end of Iran’s prolonged February-to-May 2026 internet shutdown, Bitcoin transaction activity in Chainalysis’s selected everyday-use series had recovered to over 75% of its baseline after an initial fall of around 80%, the blockchain analytics company reported Oct. 26.The rebound developed while the blackout was still in place. Some Iran-attributed activity was reaching the network during severe restrictions, while the number of people with dependable access to their funds remains unmeasured.The findings come from Chainalysis’s new Middle East and North Africa analysis, covering July 2025 through June 2026. Independent traffic observations from Cloudflare document the prolonged disruption and its…
