Chainalysis has released results from Operation Lighthouse, a multinational effort focused on criminal networks linked to child sexual abuse material, or CSAM. According to Bitcoin.com, the initiative reviewed 29,120 cryptocurrency addresses and digital identifiers across more than 100 clearnet and darknet platforms, forums, and distribution networks. The effort generated 14,300 investigative leads and identified more than 7,700 suspicious accounts, along with connected suspects spread across 125 countries. The operation was organized in New York by the National Cyber-Forensics and Training Alliance in the United States. At least nine law enforcement agencies and more than 13 private-sector and nonprofit groups took part, including Europol, the Australian Federal Police, the Royal Canadian Mounted Police, and the UK National Crime Agency. Chainalysis said the leads may later result in account restrictions, arrests, and prosecutions. It added that enforcement outcomes are expected to continue through 2027 and that the collaboration model may be extended to other forms of crypto-related crime.

Chainalysis said a global operation it led identified more than 7,700 suspect accounts linked to child sexual abuse material. Operation Lighthouse reviewed 29,120 crypto addresses and digital identifiers tied to more than 100 CSAM platforms, forums and distribution networks across the surface web and dark web. The operation produced 14,300 investigative leads across 11 crypto exchanges and payment services, and suspects were identified in 125 countries. Among them were 16 registered sex offenders. Tom McLouth, a senior intelligence analyst at Chainalysis, said the suspect pool also included military personnel, law enforcement officers, medical professionals and educators, including people with direct access to children. The multi-day sprint took place at the National Cyber-Forensics and Training Alliance in New York after months of data enrichment. Participants included Europol, the UK National Crime Agency, Binance, Coinbase, Block and the Internet Watch Foundation. Chainalysis said the results were expected to support arrests, prosecutions and account-level disruption.

Jason Hughes, VP of Development and Engineering at Ocean Mining, argues that BIP-110 has not reached anything close to broad Bitcoin network consensus and is currently on track to fail. In a guest article published by Bitcoin Magazine with his permission, Hughes said he is neither pro-BIP-110 nor anti-BIP-110, but the measurable data does not support claims that the proposal is inevitable. He cited two figures he sees as central to the debate: only 7% to 15% of Bitcoin nodes appear to be signaling support for BIP-110, depending on the crawler used, and just 0.6% of blocks over the past 60 days have signaled support. Hughes also said all major mining pools he monitors, except OCEAN, are running some variant of Bitcoin Core v30 or v31, and he sees no evidence that they are preparing BIP-110-compatible deployments. The article focuses on what miners should do as block 961632 approaches. Hughes advises miners who support BIP-110 to signal, and those who do not support it or do not care not to signal, while watching whether major pools continue producing non-signaling blocks. He wrote that BIP-110 could still be enforced if it reaches more than 51% of network hashrate by or before block 961632, but based on current data he puts its odds of success at less than 5%.

Bitcoin Core v30 plans to raise OP_RETURN data limit from 90 bytes to 100,000 bytes, sparking fears of malware injection and forced node shutdowns. Critics like Bitcoin Mechanic predict catastrophic disruptions for exchanges and mining pools, while Peter Todd dismisses the claims as unrealistic. Core developers maintain the release schedule.
