Today in crypto, StarkWare tested an experimental transaction demonstrating quantum-resistant Bitcoin spending without a fork. The SEC moved its crypto custody overhaul into White House review, while Bernstein called for Bitcoin to reclaim $125,000 by late 2026.
StarkWare tests quantum-resistant Bitcoin transaction on mainnetStarkWare researcher Avihu Levy has tested an experimental quantum-resistant transaction on the Bitcoin mainnet, in what the company described as the first transaction of its kind.
According to StarkWare, the transaction was confirmed Wednesday in Bitcoin block 964,199. Onchain data shows that it spent a 10,000-satoshi output protected by Levy’s Quantum Safe Bitcoin (QSB) scheme, with MARA Pool mining the block after receiving the transaction through its Slipstream service.
Levy’s paper and code repository said QSB combines hash-based one-time signatures with computational searches that bind an authorization to a specific transaction. The construction is intended to prevent forgery even if a quantum computer breaks the elliptic-curve cryptography Bitcoin uses.
The test moves Levy’s April proposal from theory to an onchain demonstration, showing that Bitcoin’s existing consensus rules can accommodate one form of quantum-resistant spending without a protocol change.
SEC advances crypto custody overhaul to White House for reviewThe US Securities and Exchange Commission (SEC) has sent its planned overhaul of crypto custody rules to the White House for review, moving forward with changes that could clarify how investment advisers and funds can hold digital assets for clients.
The proposal reached the Office of Management and Budget’s (OMB) regulatory review arm on Aug. 25. It has not yet been made public, and OMB can request changes before returning it to the SEC, where commissioners would vote on whether to release it for public comment.
The SEC is considering changes to existing rules or new rules under the Investment Advisers Act and Investment Company Act. The effort forms part of the regulator’s broader shift toward formal crypto rulemaking under Chair Paul Atkins, alongside a retreat from the enforcement-heavy approach of previous years.
The move comes as the Trump administration pushes its digital asset agenda while the CLARITY market structure bill remains stalled in the Senate ahead of a potential September cloture vote.
Bernstein forecasts Bitcoin to reclaim $125K by late 2026 ahead of cycle peakWall Street research company Bernstein expects Bitcoin to recover from its latest downturn, reclaim its 2025 high and set new records in the coming years heading into the peak of its historical cycle.
Bernstein expects Bitcoin (BTC) to reclaim $125,000 by late 2026 under both its base and bull cases, according to a research report published Wednesday and seen by Cointelegraph.
The company said Bitcoin gained 28% over the previous 10 days after falling about 50% from its October 2025 peak, a rebound that could signal the end of the current bear cycle.
The analysts’ call comes as institutional investors and corporate Bitcoin buyers play a bigger role in the market, which Bernstein said provided greater downside support during the latest cycle and contributed to a smaller drawdown than the 75% to 90% declines of previous cycles.
