US spot Bitcoin ETFs post best week since April with $1B inflows

Demand for US spot Bitcoin exchange-traded funds (ETFs) rebounded sharply this week, signaling renewed investor appetite after months of uneven flows, even as uncertainty persists around digital asset regulation and the security of crypto self-custody.  On Saturday, Bloomberg ETF analyst Eric Balchunas said the spot funds attracted roughly $1 billion in net inflows for the week, their strongest showing since April and third-best week since last October — a period he referred to as Bitcoins “silent IPO.”Source: Eric Balchunas  The term was popularized by investor Jordi Visser in November to describe what he viewed as a changing of the guard among Bitcoin holders. Under the theory, early investors were selling into growing demand from ETFs and other institutional buyers, creating enough supply to keep Bitcoin subdued despite substantial new capital entering the market.  That distribution coincided with a deterioration in ETF flows compared with earlier periods of stronger demand, making this weeks rebound particularly notable.

Bitcoins BIP-110 enters mandatory signaling with miner support below 3%

Bitcoin Improvement Proposal 110 entered its mandatory-signaling phase at block 961,632 on Saturday, with miners signaling support in just 51 of the preceding 2,016 blocks, or 2.53%, well below the 55% threshold required for early activation, according to the BIP-110 monitor.  Starting at block 961,632, nodes enforcing BIP-110 began rejecting blocks that did not set version bit 4, while ordinary Bitcoin nodes continued accepting both signaling and non-signaling blocks. A minority BIP-110 branch subsequently emerged, but quickly fell behind the dominant chain.  The low signaling rate makes a sustained rival chain unlikely without substantially greater miner participation. With relatively little mining support, a BIP-110 branch could advance slowly or stop producing blocks altogether.  The milestone tests whether supporters can advance a contentious consensus change without broad miner backing, potentially separating enforcing nodes from the dominant chain and escalating a dispute over how Bitcoins block space should be used.  BIP-110 seeks temporary limits on Bitcoin data  Written by pseudonymous developer Dathon Ohm, BIP-110 proposes additional consensus restrictions lasting roughly one year.  It would limit most new output scripts to 34 bytes, cap OP_RETURN outputs at 83 bytes, restrict certain data pushes and witness elements to 256 bytes, and temporarily limit several Taproot features. Unspent transaction outputs created

Crypto Weekly: ADA and Privacy Coins Outperform While XRP Slides

The aggregate crypto market cap rose from under $2.2 trillion to $2.9 trillion during the first week of August 2026. Bitcoin gained over 3% to peak above $65,300, pushing its market cap past $1.3 trillion while Cardano logged a second week of double-digit gains.   Bitcoin Reclaims $65,000 Despite CLARITY Act Setback  The first week of August delivered strong momentum across the cryptocurrency market, with aggregate market capitalization surging from a low under $2.2 trillion to reach $2.9 trillion by Aug. 8. Bitcoin spearheaded the rally, reclaiming the $65,000 threshold for the first time in August and lifting its total market cap back past $1.3 trillion.  Market data shows bitcoin gained over 3% over seven days, ascending from $62,721 to a peak just above $65,300 on Friday before consolidating above key support. Crucially, bitcoin secured these gains despite regulatory headwinds following the U.S. Senates failure to pass the CLARITY Act.  While bitcoin anchored the broader market, Cardano (ADA) emerged as the weeks standout performer, logging double-digit gains for the second consecutive week. ADA rallied from $0.174 to hit $0.211 on Aug. 6—a high not seen since June 4—fueled by news of a strategic integration between Cardano and the Injective protocol. Despite this short-term breakout,

US Senate to vote on advancing CLARITY Act in September after Thune files cloture

US Senate Majority Leader John Thune has filed cloture on a motion to take up the Digital Asset Market Clarity Act, also known as the CLARITY Act, setting up a key procedural vote on the crypto market structure bill for September.  The vote is expected after the Senate reconvenes on Sept. 15, giving lawmakers several more weeks to resolve disagreements that prevented a deal before the August recess.  The Senate Daily Press confirmed that Thune filed cloture on the motion to bring the CLARITY Act to the Senate floor for consideration. Invoking cloture requires 60 votes, meaning Republicans will need Democratic support to clear the procedural hurdle.  Thunes move puts the CLARITY Act on a path toward Senate consideration after lawmakers failed to reach an agreement before the August recess. Negotiations have been complicated by disagreements over ethics provisions and rules governing stablecoin rewards, among other issues.  Source: Eleanor Terrett  While the move marks progress for the legislation, it does not guarantee that the CLARITY Act will receive a final vote or pass the Senate. The cloture vote concerns whether to take up the legislation for consideration, rather than passage of the bill itself.  The CLARITY Act is considered a landmark piece of US crypto legislation

Bitcoin Red Team Says AI Is Finding Critical Exploits Across Core Projects

In briefThe initiative says it has scanned about 150 Bitcoin repositories and made more than a dozen vulnerability disclosures.The team is developing an open-source AI platform for auditing Bitcoin software.Developers say the effort is uncovering critical vulnerabilities across wallets, cryptographic libraries, and infrastructure.  A volunteer security initiative says it used frontier AI models to scan 150 Bitcoin repositories and found more than a dozen vulnerabilities as developers increasingly use artificial intelligence to audit blockchains.  In a post on X earlier this week, AnchorWatch CEO Rob Hamilton said the group has spent about $20,000 on AI services while building a “Bitcoin red team” platform.  “We have been working around the clock, with ~$20,000 of spend up to this point across different services,” he wrote. “Funding is secured, I appreciate all the gestures for donations but it is not necessary. The bill is taken care of.”  A red team refers to cybersecurity professionals who test software from an attackers perspective, probing for vulnerabilities before they can be exploited.  According to Hamilton, the Bitcoin red team uses Kimi K3 alongside OpenAI‘s GPT Sol, Anthropic’s Claude Fable and Opus models, and Z.ais GLM 5.2 to identify vulnerabilities and generate supporting documentation.  “We also have been connected with OpenAI for some

US court backs Bybits bid to trace funds from $1.5B North Korea hack

United States court records unsealed on Thursday show that a federal judge backed crypto exchange Bybits effort to trace assets stolen in the $1.5 billion North Korea-linked hack by granting the company expedited discovery.  According to the records, Bybit filed the lawsuit under seal on June 18 against North Korea, its Reconnaissance General Bureau, the Lazarus Group and 20 unidentified defendants. The court granted Bybits request for expedited discovery on June 19.  The discovery authority gives Bybit a practical route to identify alleged intermediaries and pursue a small portion of stolen assets that remains traceable, rather than relying solely on a judgment against North Korea.  In its complaint, Bybit alleged that some traceable assets reached exchanges operating or maintaining infrastructure in the US. The company sought account-holder identities, balances and transaction histories, saying certain platforms had indicated they would cooperate after receiving a court order.  Bybit says 90% of stolen funds became untraceable  Bybit also obtained a temporary restraining order on June 19 preventing the unidentified defendants from transferring certain traceable assets. The court renewed the order on July 16 and partially granted Bybits request for a preliminary injunction on July 30. Some exhibits and other records remain sealed.  As of the June 18 filing, Bybit

Coldcard Hack: Bitcoin Losses and Seed Flaw Explained

In the latest Bitcoin news today, Analytical estimates from Galaxy Research, cited by analytics account Lookonchain, indicate that total losses tied to the Coldcard hack have reached approximately 2,055 Bitcoin (BTC), worth $130 million, across more than 7,700 victim addresses.  The estimate follows reports of multiple suspected on-chain sweep waves linked to a seed-generation flaw in devices made by Canadian firm Coinkite.  The flaw affected how seeds were generated on vulnerable firmware, allowing attackers to derive and test candidate keys offline when they could determine or sufficiently constrain relevant device information.  EXPLORE: Best Meme Coins to Buy for August  Bitcoin News Today: Coldcard Firmware Flaw and Weak Randomness  March 2021 firmware integration error routed seed generation to a deterministic software pseudorandom number generator (PRNG) rather than the STM32 hardware random number generator (RNG).  The production configuration defined the hardware-RNG macro as zero, while the underlying libngu library checked whether the macro existed rather than whether it was enabled, binding the build to MicroPythons Yasmarang fallback.  The MicroPython fallback was initialized from chip unique identifiers and timer registers and did not collect fresh entropy after initialization. Block said an attacker able to determine or sufficiently constrain the device UID, timer state and prior RNG-call history could reproduce candidate
