Farside’s currently reported $137.3 million U.S. spot Bitcoin ETF inflow on Aug. 17 rested heavily on Fidelity, leaving the session short of a market-wide demand signal.Fidelity Wise Origin Bitcoin Fund, or FBTC, supplied $111.9 million, equal to 81.5% of the displayed total, according to Farside’s live table. ARKB added $14.2 million and MSBT added $11.2 million. Those were the only three numeric inflows in the row; the remaining reported fund entries were 0.0.BlackRock’s iShares Bitcoin Trust, or IBIT, did not have a numeric entry. Farside displayed a dash, which its table visually distinguishes from 0.0 without providing a legend for…

Ethereum developers are weighing a new defense against predatory trading bots that exploit pending transactions before they reach the blockchain.The problem stems from Ethereum’s public mempool, a transparent waiting room where transactions can be inspected before execution. That visibility lets automated traders spot profitable orders and place their own transactions around them, extracting value from users before a trade settles.The practice has become most closely associated with sandwich attacks. A bot spots a pending swap, buys the same asset first to move the price against the user, then sells immediately after the victim’s trade executes at the worse price.While estimates…

Coinbase’s announced Aug. 17 cutoff for USDC deposits and withdrawals on Noble had passed, but Circle’s public Noble guide was still telling users to use Coinbase and select Noble as the network as of press time Aug. 18.Coinbase’s July 15 notice did not specify a clock time or timezone for the cutoff. It warned users not to send USDC to Coinbase’s Noble deposit addresses after Aug. 17 because those funds may not be recoverable. The warning identifies a transfer risk, not evidence that users have already lost funds.Coinbase named Ethereum, Base, Solana, Arbitrum, Optimism, and Polygon as other supported USDC…

A paper accepted for Crypto 2026 in Santa Barbara says it resolves a theoretical gap in permissionless consensus by replacing a public beacon that supplied participants with fresh random values at regular intervals.The problem is how parties can reach Byzantine agreement without knowing in advance who is participating, except for an upper bound on the number of participants, and without relying on a public-key infrastructure. Bitcoin helped motivate this line of research, but the public records do not present the new work as a Bitcoin upgrade or a change for any live network.

One of the smallest details on the new 1776 ~ 2026 U.S. Constitution quarter carries a clever anniversary message: the clock on Independence Hall, depicted on the reverse, is set to 2:50 in a nod to America’s 250th anniversary. An enlarged view of the 1776 2026 US Constitution quarter shows the Independence Hall clock set to 250 as a subtle reference to the 250th anniversary of American independence The detail is easy to miss at actual quarter size. Enlarged views reveal the minute hand pointing toward 10 and the hour hand approaching 3, making the intended time clear. The U.S.…

Early Bitcoin developer and self-proclaimed “Bitcoin thought leader,” Peter Todd, has revived debate over Bitcoin’s 21 million-coin limit and whether Bitcoin tail emission could help fund proof-of-work security as block subsidies shrink. The dispute turns on whether transaction fees alone can eventually fund adequate security.The clip posted Aug. 16 framed Todd as saying Bitcoin should eliminate the cap. Todd did not call for an immediate cap change; he framed tail emission as a long-term design question. In a July 23 talk at Bitcoin++ Toronto, Todd argued that Bitcoin is moving from subsidy-supported security toward a fee-dominant model. He said there…

Key takeaways Chainlink trades around $9.42 after gaining more than 14% last week. A long-to-short ratio of 0.76 and negative funding point to weakening derivatives sentiment. Spot LINK ETFs attracted $2.07 million on Monday, their largest daily inflow since July 22. Losing support at $9.39 could trigger a pullback toward $8.94 and the $8.60–$8.50 region. Chainlink (LINK) is struggling to overcome resistance near $9.56 on Tuesday, pausing after rallying more than 14% during the previous week. Weakening derivatives indicators suggest that bullish momentum may be losing strength. However, renewed institutional demand through spot LINK exchange-traded funds could support another attempt…

Galaxy’s Aug. 7 snapshot of Aave V3 Core found 19,073 loans on the protocol after applying standard filters. Fewer than 9% of those positions are using Aave’s E-mode setting, account for roughly half of all outstanding debt on the platform, and show an Ethereum correlation trade.Galaxy puts their debt-weighted loan-to-value near 90%, their average health factor around 1.06, and their debt-to-equity ratio near 10.7 times. The remaining 91% of positions carry a debt-weighted LTV closer to 49%, a health factor around 1.79, and debt-to-equity near 1.07 times, a profile with far more room to absorb a bad day.Borrower groupShare of…
