According to the Ontology blog, its core development team discovered potential security vulnerabilities during routine security checks. Due to a high emphasis on the security and integrity of the mainnet, Ontology has immediately suspended block production on the Ontology mainnet to allow the technical team and validators to conduct a comprehensive security review of the network and related components. Ontology stated that no security incidents have been confirmed at this time, and there are no indications that user assets have been lost or stolen. ONT, ONG, and other on-chain assets are currently assessed to be unaffected; this suspension is a preventive security measure rather than a response to confirmed asset losses or ongoing attacks.During the review period, block production will remain suspended, and on-chain transactions cannot be processed. Users do not need to transfer or take any action regarding their ONT, ONG, and other on-chain assets, but should avoid conducting time-sensitive on-chain transactions until the network officially confirms its restoration. The duration of the suspension has not yet been determined, and the team will prioritize the comprehensiveness of the security review over speed; block production will not resume until the network has been thoroughly assessed and confirmed to be secure. The Ontology team is collaborating with validators and ecosystem partners to address this matter and will update progress through official channels, with a separate announcement to be made before and after the network restoration.

Polygon disclosed multiple previously undisclosed security vulnerabilities recently fixed through two hard forks, Austin and Kyoto, which could affect its proof-of-stake network. The vulnerabilities involve Polygon's Bor and Heimdall clients, including denial-of-service risks, validator resource exhaustion, and defects affecting checkpoint and milestone processing.Polygon stated that the fixes were privately tested before being deployed to the mainnet and publicly disclosed. The most severe issue involved Heimdall, where carefully crafted transactions could force validators to perform excessive processing work, disrupting the network. The Austin hard fork also fixed two denial-of-service risks in Bor that could slow down block processing or cause node crashes. Polygon indicated that these vulnerabilities were not exploited on the mainnet, and the fixes were proactively completed before the details of the vulnerabilities were made public.

As Bitcoin's price rose to about $79,007 on Sunday, the 840,447 Bitcoins held by Michael Saylor's Strategy had a total value of approximately $6.64 billion, about 4.4% higher than its average purchase cost of $75,653, resulting in an unrealized gain of over $2.8 billion. Saylor posted a chart of his holdings on the X platform with the caption "We're Back," sparking speculation in the market about a possible resumption of buying.Strategy typically discloses its weekly Bitcoin purchases on Monday mornings, and the company has not increased its holdings for about two months. Recently, Strategy raised $334 million by selling MSTR stock without touching its Bitcoin holdings and sold a small amount of Bitcoin to pay preferred stock dividends and buybacks, indicating a shift in capital management strategy. Bitcoin fell to $76,877 last Friday due to comments from Federal Reserve Chairman Waller about inflation cooling less than expected, but it remains far below the historical high of about $126,000 in October.

CryptoQuant analyst Darkfost stated that during the recent rise of Bitcoin to $80,000, the average unrealized profit margin for short-term holders (STH) is close to 15%. The estimated holding cost is currently around $70,100, and the profit level has reached the highest since July 2025. This range is often accompanied by significant profit growth, which also makes the holding mentality of short-term holders more unstable, and some investors may choose to take profits. Therefore, it is not surprising that Bitcoin is temporarily stagnating around $80,000.

According to CoinDesk, six Bitcoin wallets that were active from 2011 to 2014 and had not moved since transferred a total of 553.59 BTC, worth about $40 million, between August 16 and 26. Five of the wallets sent Bitcoin to addresses with no known exchange associations, while one wallet transferred 40 BTC to the German crypto custody and trading service provider Boerse Stuttgart Digital.

U.S. short-term Treasury yields rose. Federal Reserve Chairman Waller emphasized in a highly anticipated speech that the Fed needs to curb rising consumer prices, alleviating some market concerns about its ability to combat inflation.During Waller's speech, short-term U.S. Treasuries were sold off, while long-term Treasuries rose. The yield on the two-year Treasury increased by 5 basis points to 4.28%, while the 30-year yield decreased by 1 basis point to 5.19%. These changes indicate that the market expects the Fed may need to raise short-term rates. Since Waller held his first press conference in June, bond traders have had doubts about his policy stance. At that time, Waller emphasized the need to lower inflation and showed a hawkish stance.Since the global economy reopened from the pandemic in 2021, U.S. inflation has remained above the Fed's 2% target. However, in July, the Fed again kept rates unchanged, and Waller did not indicate whether a rate hike might occur this year. Subsequently, long-term Treasury yields surged as traders demanded higher returns to compensate for the risks posed by rising inflation.Waller warned on Friday that inflation has not shown meaningful signs of slowing and stated that policymakers must be confident that inflation is improving; otherwise, the central bank "has work to do." He also reiterated that policymakers will bring the inflation rate back to the 2% target and emphasized that this goal is clear and fixed.
