first_img Claude of Anthropic cracked the 25-year puzzle of NSA's elliptic curve

Anthropic's AI model Claude cracked a 25-year-old puzzle in the field of cryptography in less than 30 minutes, tracing a set of numbers provided by the National Security Agency (NSA) to the U.S. government in the late 1990s back to a common random number generator that used timestamps from 1997 and 1998. These numbers have long been suspected of hiding a backdoor.In 2000, the National Institute of Standards and Technology (NIST) adopted a set of elliptic curves provided by the NSA, but the NSA never explained where the partial numbers (seeds) used to generate these curves came from. After Edward Snowden disclosed that the NSA had attempted to undermine cryptographic standards, suspicions about its hidden backdoors intensified. Cryptographers Neal Koblitz and Alfred Menezes discussed this controversy in a 2015 paper, and security researcher Steve Weis spent years searching for answers. In 2023, Filippo Valsorda and others even set up a bounty for this.Claude traced the five NIST curve seeds back to the random number generator lrand48 in an old C software library and reproduced the widely used P-256 curve sequence, finding an exact match with the published seeds among the 1842 candidates. Anthropic stated that this significantly reduces the possibility of hidden weaknesses, and users of NIST curves do not need to make any changes. Bitcoin is unaffected, as its wallets use the simpler secp256k1 curve, which has almost no room for secretly implanted weaknesses. The bounty of $36,864 will be donated to the nonprofit organization Internet Security Research Group behind Let's Encrypt.

first_img The Curve soft liquidation mechanism allows hundreds of loans to survive in a liquidation state for several weeks

According to CoinDesk, data from Curve Finance shows that its lending market has recorded a total of 704 "soft liquidation" events, involving 602 borrower addresses, with a median duration of 14.5 days, of which a quarter lasted at least 38.9 days, and some positions remained within the liquidation range for several months. Of these soft liquidations, 476 began in the first half of 2026. Unlike traditional lending protocols such as Aave and Compound, Curve's LLAMMA system does not sell off collateral all at once after the price drops below a threshold, but gradually converts collateral into borrowed assets within a price range. If the price rebounds before the loan completely fails, some or all of the conversions may be reversed. This means that borrowers are not in a grace period; their collateral has been partially liquidated during the loan's duration, but they still have the opportunity to restore their positions if the price reverses. However, soft liquidations are not without costs. Data shows that borrowers may still incur losses due to transaction fees, conversions, rebalancing, interest, and bid-ask price fluctuations, and if the market remains unfavorable, positions may still fall into hard liquidation. Curve Finance is a mainstream DeFi protocol focused on stablecoin exchanges and crvUSD lending, currently holding approximately $1.35 billion in deposits, with a DEX trading volume of about $3.4 billion over the past 30 days and active loans of about $46 million.

Analysis: The VIX curve is rising, and anxiety in the stock market is increasing as the U.S. midterm elections approach

Although Nvidia's upcoming earnings report and Federal Reserve Chairman Waller's speech at the Jackson Hole annual meeting are the main events of interest for investors this week, traders in the stock derivatives market have already begun preparing for potential volatility increases around the November U.S. midterm elections.Traders focused on volatility in the futures market linked to the VIX index have noted signs indicating that demand for hedging S&P 500 index volatility has increased before and after the elections. VIX futures expiring in September are currently trading at around 17.4, but October contracts have risen to 19, and November contracts have further increased to 19.7.Matthew Thompson, co-portfolio manager at Little Harbor Advisors, stated, "The U.S. elections are approaching, and you are entering a time window where the elections will impact the VIX. You can already see this 'backwardation' in the term structure of VIX futures."A study by analysts at the Chicago Board Options Exchange Global Markets shows that since 1945, in 80% of midterm election years, actual volatility has been higher than the previous year, with an average increase of 3.5 volatility points. In years when both the White House and Congress are controlled by the same party, actual volatility increases by an average of 6 volatility points.
