Anthropic researcher resigns, stating that AI may go out of control next year

Anthropic researcher Jacob Coxon announced his resignation and is preparing to leave the AI industry. He has conducted pre-training research at OpenAI and Anthropic over the past three years. He pointed out that neither company has responsibly advanced AI and are competing to create superintelligence that can continue to enhance its own capabilities, "betting our lives on it."He switched from OpenAI to Anthropic this year because the latter places more emphasis on model safety. Coxon acknowledged that Anthropic's safety work is serious, but believes that as long as companies are racing to be the first to create AGI (artificial general intelligence that surpasses humans in a wide range of tasks), safety compromises are unavoidable, and self-discipline from a single company cannot solve the problem. His assessment of the two companies is: many people inside OpenAI still do not truly realize how great this risk is; Anthropic knows the risks but believes others are unreliable, so they must create it themselves first.Coxon stated that some AI practitioners are much more pessimistic privately than they express publicly, and are even worried that AI could destroy humanity before the end of this decade. He personally judges that in the most radical scenario, AI could go out of control by the end of next year, so such decisions should not be made solely by the engineers of a few companies.

first_img Hacken Report: Half of USDT is controlled by only two signing keys

Blockchain security company Hacken released an assessment report indicating that approximately half of the circulating USDT (about $91.3 billion on the Tron network) is controlled by a 2-of-3 multi-signature contract, which lacks built-in delays, cancellation processes, or reliable revocation mechanisms. Attackers only need to compromise two signature keys to change contract ownership, mint tokens, freeze addresses, clear frozen balances, or set transfer fees without accessing any user wallets. Hacken also discovered that Tether reuses the same set of six signature keys across three chains: Ethereum, Avalanche, and Celo, posing a risk of cross-chain spread.Meanwhile, stablecoin rating agency Bluechip upgraded Tether's company rating from D to C, citing that KPMG's audit showed Tether's reserves exceeded liabilities by $6.8 billion as of December 31, 2025. This is the first time Bluechip has adopted the expanded SMIDGE methodology, which incorporates Hacken's technical risk analysis. However, Hacken only gave USDT a cybersecurity score of 3.3 out of 10 and pointed out that the USDT smart contract does not have automatic reserve proof checks or a token minting cap. Once signers authorize a transaction, the contract can mint an unlimited number of tokens without a bank reserve proof.Hacken stated that it has not yet completed an equivalent assessment of Circle's USDC, and Bluechip's previous B+ rating for USDC was based on an old methodology, which cannot be directly used for technical comparison.

Report: The concentration of the DeFi treasury market is significant, with the top 5 managers controlling 69% of the funds

Vaults.fyi released the report "2026 DeFi Custody Market Status," covering 856 vaults, 131 custodians, and 18 protocols, with a total locked value of approximately $11.29 billion. Over the past year, the TVL on the supply side of DeFi decreased by 41.8%, while the TVL of custody vaults grew by 39%, increasing market share from 5.24% to 12.51%. The top 5 custodians manage 69% of the funds, and the top 10 account for 79.1%. The leading landscape has changed dramatically, with Sentora and Concrete not making the list a year ago, now ranking second and fourth, respectively, while Usual dropped from fourth to thirty-fourth.Morpho ranks first among protocols with a custody TVL of 46.2%, with the remaining 53.8% distributed across the other 17 protocols. Bitcoin collateral accounts for 54.1% of Morpho's top 25 stablecoin vaults (approximately $3.71 billion). In terms of address concentration, weighted by TVL, a single address holds an average of 47% of vault shares, with the top ten addresses collectively controlling 74%. About 33% of the custody funds require a multi-step redemption process, with a 7-day annualized yield median of 4.82%, which is 98 basis points higher than instant redemption vaults.The report also points out that traditional financial institutions such as Société Générale, Apollo, and JPMorgan have begun to deploy custody vault strategies.
