Google's Multiparty Compute crypto custody system is in private preview for companies and is being tested by several major financial firms and parent company Alphabet. The platform manages signing keys for digital assets, with independent signing parties holding separate key shares, so multiple parties must come together to sign without assembling the complete private key in one location. Institutions choose how many signing parties must approve a transaction. The documentation lists support for Bitcoin and Ethereum, while Solana support is marked as coming soon, and the system is not generally available. The speaker argues that self-custody has been weakened as AI threats grow, and that this could be a future solution for safely custodying Bitcoin.

- AI found a way to crash bitcoin nodes on Windows and Macs. It's now public
- AI agents help rescue ETH’s Glamsterdam fork, ‘Steal My Bitcoin’ site: Hodler’s Digest
The second and final testnet for Ethereum’s Glamsterdam hard fork was cancelled after ChainSecurity found vulnerabilities in two gas-scaling proposals (EIP-8037/8038) that could have affected at least 13 DeFi contracts. Derek Chiang of Eth Labs said the flaw was found only a few minutes before midnight, forcing everyone to scramble, and the Hoodi dress rehearsal will not be rescheduled until the second-order effects are fully analysed. To speed up the review, researchers from Eth Labs and the Ethereum Foundation deployed AI agents that coordinated through a message board in a GitHub repo, and a second board now examines EIP-8198 (“Quick Slots”) for the proposed Hegota fork. Separately, the ‘Steal My Bitcoin’ site, which has not been patched against the PHP2Shell vulnerabilities, holds the key to a Bitcoin wallet worth around $2000 and had gone 25 hours without a successful hack at the time of writing.
- Bitcoin Core Rewrites Its Security Policy for a World Where AI Finds Bugs in One Prompt
Bitcoin Core has updated its security policy so that bugs that are easily discoverable will be patched quickly rather than kept under a long embargo. The project will backport fixes to all maintained releases, ship a new version as fast as possible, and publish an advisory, since large language models have greatly lowered the effort needed to find such flaws and a quiet patch would accomplish little. The change was proposed by Chaincode Labs developer Antoine Poinsot and merged on Thursday. The article links the shift to AI-driven bug discovery, noting that an AI-driven audit logged nearly 5,000 findings across hundreds of crypto projects in early August, and that developers have patched AI-surfaced bugs in Lightning implementations and hardware wallets, while one Bitcoin bridge shut down.
- Bitcoin Core changes security rules as AI makes finding code bugs dangerously easy
Bitcoin Core has changed its security policy so that vulnerabilities an AI model could rediscover with a simple prompt will be quickly disclosed and patched, replacing embargoes that could last about a year. According to developer Antoine Poinsot, reports of easily rediscovered flaws rose as LLMs lowered the bar for finding certain bugs, though fixes may get less testing before reaching users. A volunteer group of 16 developers ran AI models across 390 bitcoin projects in about a day in late July, logging 4,962 findings, 85 of them critical. Separately, a Coldcard hardware-wallet firmware flaw dormant since 2021 let attackers drain 594 BTC in 25 minutes on July 30, with losses nearing $114 million across four sweeps.
- Bitcoin Core changes security policy as AI makes bugs easier to find
Bitcoin Core is changing its security disclosure policy because large language models have made some flaws easy to rediscover, so long embargoes offer little protection. Under the new policy, vulnerabilities deemed easily discoverable will be fixed as soon as possible across all maintained major versions, with security advisories published alongside the updates. Other flaws will follow severity-based schedules: low-severity bugs will be disclosed two weeks after the fix is released, while medium and high-severity bugs will be disclosed two weeks after the last affected release reaches End of Life, typically a year after the fix. The change follows a volunteer Bitcoin Red Team report of nearly 5,000 potential issues across 390 projects in August, though only about a fifth had been reproduced at that point.
- ‘Wow, it’s a real discovery’: Claude cracks a 25-year NSA number mystery
An Anthropic AI model traced five seeds for NIST elliptic curves, supplied by the NSA in the late 1990s, to an ordinary random-number generator fed with 1997 and 1998 timestamps, in under 30 minutes. The finding makes a hidden NSA backdoor less likely and requires no action from NIST curve users, though questions remain about how some elements were chosen. Bitcoin was not affected because it uses secp256k1, a simpler curve with little room to hide a weakness, though sufficiently powerful quantum computers could eventually pose a separate threat. The 25-year puzzle had a bounty that started at $12,288 and could rise past $36,000 if donated to charity.

- Nvidia Reports Nov. 17. History Says What Its Stock Usually Does Next.
Nvidia will report results for its fiscal third quarter of 2027 after the close on Nov. 17, with shares near $205, about 14% below their Oct. 6 closing high of $239.24. Revenue beat the top of management's forecast range in each of the past 10 reports, yet the stock fell the next trading day after six of them, with the largest drop about 8.5% in February 2025. Most of those declines were recovered by the next report roughly three months later, though the roughly 9% gain after the August report has since faded to about 10% below its post-report close. Nvidia guides for third-quarter revenue of $108.0 billion, plus or minus 2%. The author concludes history is not a strong reason to avoid the stock before the report, leaning toward buying before Nov. 17 rather than guessing the next day's move, with shares trading at about 14 times the consensus fiscal 2028 EPS estimate of $15.80.

- Palantir's U.S. Revenue Soars 119% as Commercial Revenue Surpasses Government Revenue for the First Time. Here's Why Its Growth Is Still Surging, Even as Other AI Stocks Falter
Palantir reported Q3 revenue of $2.3 billion, up 96% year over year and its fastest growth on record, with EPS of $0.44, up 144%, beating consensus estimates of $2.2 billion and $0.41. U.S. commercial revenue rose 148% to $984 million, surpassing U.S. government revenue of $953 million for the first time. Management raised full-year revenue growth guidance to roughly 91% from 82%. The article notes the stock trades at 125 times earnings with a PEG ratio of 0.53, and the author views the outlook positively while cautioning that the premium valuation could lead to a swift and severe rerating if results fall short.
- Apple beats sales and profit expectations but AI costs weigh on holiday sales
Apple beat analysts' expectations with record revenue for the July–September quarter, driven by iPhone and services sales, but higher AI-related costs will weigh on margins. CEO John Ternus, who succeeded Tim Cook in September, said the company is closing the year with its most ambitious lineup and hinted at a strong holiday season, including the foldable Duo. CFO Kevan Parekh guided gross margin to 45% to 46%, down from 47.9% in the September quarter, citing higher memory costs and costs tied to ramping Siri AI, which uses Google's Gemini model. Analysts had expected Apple to spend about $11 billion over the 12 months to September, a fraction of the more than $700 billion that Microsoft, Alphabet, Amazon and Meta are on track to spend this year. Parekh said AI gives customers a compelling reason to upgrade.
- Alphabet Lost $500 Billion in Market Value. Should You Really Buy AI Stocks Now?
Alphabet shares fell 13% in one session, their worst trading day ever, after parts of its earnings report disappointed investors and wiped out about $500 billion in market value. The concern centers on AI infrastructure spending: Alphabet kept its capex forecast unchanged at $195 billion to $205 billion, and free cash flow came in at negative $9 billion versus analysts' estimate of $2.7 billion. Google ads still accounted for 64% of total revenue, while the cloud business posted a record 103% revenue gain to more than $30 billion. Alphabet, Amazon, Microsoft and Meta together aim to spend more than $700 billion this year on infrastructure. The author argues that for most investors, the recent decline is a chance to buy at an attractive price, though more volatility could follow.
