However, the proposal failed to attract significant miner support. It reportedly received only around 2.5% support before mandatory signaling began.
A separate chain launched by supporters subsequently mined only two blocks over roughly eight hours before activity stalled. The chain faced the additional challenge of maintaining Bitcoin-level mining difficulty without the same economic incentives or market liquidity as the main Bitcoin network.
The proposal generated significant debate among Bitcoin developers and advocates.
Supporters argued that limiting certain forms of blockchain spam could help preserve Bitcoin's blockspace for financial transactions. Critics, however, warned that introducing restrictions at the consensus level could undermine Bitcoin's neutral and predictable rules.
The debate highlights a long-running question for Bitcoin: how should the network balance limited blockspace, transaction utility and permissionless data use without introducing censorship into the protocol?
CLARITY Act vote moves to September
U.S. cryptocurrency regulation also remained in focus after the Senate postponed a procedural vote on the CLARITY Act.
The legislation is intended to establish a clearer regulatory framework for digital assets and define responsibilities between U.S. financial regulators.
The Senate is now expected to consider the procedural vote on Sept. 15, giving lawmakers and industry groups additional time to negotiate unresolved provisions.
The legislation still faces a difficult path because Senate approval requires enough support to clear the procedural threshold before lawmakers can move toward final passage.
For the Bitcoin market, the outcome could have broader implications for exchanges, digital-asset businesses, developers and institutional participants operating in the United States.
Bitcoin security researchers uncover thousands of issues
Bitcoin's security landscape also came under scrutiny as the volunteer Bitcoin Red Team expanded its AI-assisted review of Bitcoin-related software.
The group reported finding thousands of potential issues across open-source projects, including critical and high-severity vulnerabilities.
The initiative gained additional attention following recent attacks involving cryptocurrency wallets and infrastructure. The researchers are combining automated AI analysis with human review to identify weaknesses that could potentially be exploited.
The effort highlights an important issue for the Bitcoin ecosystem: while Bitcoin's core protocol is highly scrutinized, the wider infrastructure surrounding it includes wallets, payment systems, applications and other software that can introduce additional risks.
That distinction became particularly important after vulnerabilities in third-party infrastructure resulted in cryptocurrency losses.
Ethereum staking debate spreads across the crypto market
Ethereum researchers also proposed changes to the network's staking economics that could reduce validator rewards as the percentage of staked ETH increases.
The proposal, known as EIP-8363, would progressively reduce issuance and could eventually eliminate new protocol issuance if the proportion of staked ETH reaches a specified threshold.
Supporters argue that Ethereum may not need to continue increasing staking incentives indefinitely as more ETH becomes locked to secure the network.
Critics, however, warn that reducing rewards could hurt smaller validators, increase staking concentration and affect decentralized finance applications that rely on liquid staking.
Although the proposal concerns Ethereum rather than Bitcoin, the debate is relevant to the broader crypto market because changes to major blockchain monetary policies can influence investor expectations around supply, staking and network security.
Bitcoin ETFs record strongest week in months
U.S. spot Bitcoin ETFs delivered one of the strongest weekly performances of the year, attracting approximately $853.5 million in net inflows across five consecutive trading sessions.
The inflows represented a major reversal from the previous week's withdrawals and were roughly five times larger than the total amount attracted by the funds throughout July.
BlackRock's IBIT accounted for the majority of the demand, attracting an estimated $693 million during the five-session period.
Fidelity's FBTC, Bitwise's BITB and ARK 21Shares' ARKB also recorded positive inflows, although smaller funds experienced withdrawals.
The renewed ETF demand suggests institutional interest in Bitcoin remained resilient despite BTC trading within a relatively narrow range.
Ethereum ETFs also recorded approximately $244 million in weekly inflows, bringing combined Bitcoin and Ethereum ETF demand to roughly $1.1 billion.
SoSoValue Bitcoin ETF data
Bitcoin market remains rangebound
Despite the strong ETF inflows, Bitcoin continued trading below the $65,000 level during the week.
The disconnect between strong institutional ETF demand and relatively limited price movement suggests that other market forces are still preventing a decisive breakout.
Bitcoin's recent price action has remained concentrated around the $60,000–$65,000 area, with traders watching whether sustained ETF inflows can eventually translate into stronger spot demand.
A sustained move above the upper end of the range could improve market sentiment, while renewed selling pressure could push Bitcoin back toward lower support levels.
Crypto derivatives activity continues to weaken
The broader derivatives market also showed signs of declining activity.
Centralized exchanges recorded approximately $4 trillion in perpetual futures volume during July, marking the lowest level since late 2023, according to CryptoRank data.
Binance led the market with approximately $1.4 trillion in monthly perpetual futures volume, followed by OKX and Bybit.
Decentralized perpetual futures volumes also declined, falling to approximately $531 billion in July.
The decline suggests traders have become less aggressive with leveraged positions as Bitcoin remains trapped within a relatively narrow trading range.
Lower derivatives activity can reduce immediate speculative pressure, but it can also indicate that traders are waiting for a stronger catalyst before increasing exposure.
Crypto security remains a growing concern
Security continued to be one of the biggest issues across the digital-asset industry.
Physical attacks targeting cryptocurrency holders reportedly generated more than $30 million in losses during the first half of 2026, while software vulnerabilities and infrastructure exploits continued to expose weaknesses across wallets and crypto applications.
For Bitcoin users, the developments reinforce the importance of secure self-custody practices and careful evaluation of wallet and payment infrastructure.
The Bitcoin network itself can remain secure while applications built around it still contain exploitable vulnerabilities.
Bitcoin enters another important week
Bitcoin's latest week combined strong institutional ETF demand with continued uncertainty around regulation, protocol development and ecosystem security.
BIP-110's failure to gain meaningful support demonstrates how difficult it can be to change Bitcoin's consensus rules, while the delayed CLARITY Act vote shows that regulatory uncertainty remains unresolved in the United States.
At the same time, the $853.5 million ETF inflow streak provides a more constructive signal for institutional demand.
For now, Bitcoin remains caught between strong investment-product demand and relatively subdued market activity. The next major catalyst could come from ETF flows, U.S. regulatory developments or a decisive breakout from Bitcoin's current trading range.
