Bittensor has launched a quantum-resistant wallet with support for post-quantum signatures and optional automatic key rotation. According to Foresight News, the wallet supports ML-DSA-65, Falcon-512 and Falcon-1024; ML-DSA-65 has been standardized by the U.S. National Institute of Standards and Technology (NIST). It works with both coldkeys and hotkeys for TAO transfers, staking and validator weight settings. The optional key-rotation feature switches to a new signing key after a user-signed transaction is recorded on-chain. The old key can no longer authorize transactions for the account, while its address, balance and staking remain unchanged; users do not need to replace their recovery phrase each time. Wallets without key rotation enabled require no registration. Enabling rotation requires registration and a one-time, permanent lock of 0.2 TAO. Existing wallets can still be used. Users can move funds and staking to a new account through a transfer or coldkey swap.

The selloff in US stocks paused, with dip buyers moving in to support the bruised artificial-intelligence trade after the S&P 500's steepest drop in more than a year, Bloomberg reported. S&P 500 futures rose 0.4%, and Nasdaq 100 contracts gained 1.4%, set to pare part of Thursday's 6.4% decline. Worries about tighter data center regulation shaved around $3 trillion off the index in the previous session. The turmoil kept reverberating: the MSCI Asia Pacific Index fell 3.9%, the Stoxx Europe 600 dropped 1.2% and the MSCI Emerging Markets Index lost 2.7%, while Dow futures slipped 0.6%. Treasuries halted their haven-driven advance ahead of Friday's payrolls report, the dollar outperformed all major peers and Brent traded around $97 a barrel. Global markets have been whipsawed this week. Investors first bet a Democratic sweep would hasten an end to the Iran war, before fears of a clampdown on the data center buildout overwhelmed that optimism. Chipmakers bore the brunt, with a key US semiconductor gauge down almost 16% since Monday. An ETF tracking US chip stocks rebounded 4.5% in premarket trading and Nvidia jumped more than 4%, though Amazon and Apple remained under pressure. Data center firm IREN soared 18% after reporting a surge in AI cloud revenue. Roberto Scholtes at Singular Bank said he expected a modest rebound as opportunistic buyers picked up some of the hardest-hit stocks, adding that investors would look for clues about the Democratic Party's intentions and that a credible sign a nationwide moratorium was off the table could help reverse sentiment. Santiago Mateo Yanguas at CaixaBank Asset Management said Thursday felt close to capitulation, and that while it may be too early to call a bottom, much risk had already been flushed out and fundamentals were not validating the most bearish AI concerns. Hedge fund losses deepened the unease: Walleye Capital is returning cash after its worst month since March 2020, Greg Coffey's Kirkoswald posted its worst-ever monthly decline, and credit fund Arini Capital Management lost more than 12% last month. Bloomberg Economics expects payrolls to rise 26,000 with unemployment near 4.2%, neither of which would deter the Fed from its path to a December rate hike, economists including Anna Wong wrote. Francisco Simon at Santander Asset Management said a strong jobs report could calm nerves by reinforcing confidence in the economic cycle, though focus is likely to stay on AI and data centers, and that cyclical employment still has room to expand. Other moves: 10-year Treasury yields were little changed at 4.84%, gold slipped 0.4% to $4,072.05 an ounce, Brent fell 1.3% to $96.98, bitcoin rose 0.4% to $76,054.23 and ether added 0.4% to $2,235.54.

BNB Chain announced that BEP-706 will be included in the Jenner hard fork, adding a precompiled contract at address 0x70 to provide smart contracts with millisecond-level block timestamps. According to Odaily, the new interface will let developers read timestamps in milliseconds, while the existing `block.timestamp` value and second-based timing logic will remain unchanged. The feature is intended for applications requiring subsecond precision, including quote settlement with validity periods of several hundred milliseconds, auction deadlines and checks on price oracle data freshness. The precompiled contract will cost 20 gas, with additional costs for the call and memory. BNB Chain advised developers to check unit consistency between seconds and milliseconds and verify that calls succeed and return the expected 32 bytes of data.

The Ethereum Foundation said security firm ChainSecurity recently found that certain invariants used by some projects could stop holding after the Glamsterdam upgrade. According to Odaily, the risks involve EIP-8037 and EIP-8038, which change gas fees for some operations and state gas accounting. The All Core Developers meeting decided to delay the hard fork and not start the fork on the Hoodi testnet until the issues are resolved. The foundation said it is reviewing the changes with several audit firms and conducting an internal audit, but cannot cover every project’s on-chain and off-chain code. The foundation urged contract developers and auditors to check whether their projects rely on the eight invariants. It has created a dedicated GitHub repository with explanations, examples and prompts for projects to assess potential effects and possible specification changes.
