Jinse Finance reported that this week, Bitcoin Core developers mistakenly claimed that nearly 40% of Knots nodes—Core's largest competitor—were double-counted, creating a false impression of its actual scale being exaggerated. They cited technical criticism of the number of reachable Knots nodes, alleging (before many posts were deleted) that as many as 39% of nodes (1,758 out of 4,468) were double-counted due to so-called "Sybil attacks," thus "artificially inflating the number of Knots users." For context, the two most popular Bitcoin node software versions currently are: Bitcoin Core (dominating approximately 80-88%) and Knots (holding about 12-19% share). The specific percentages depend on the estimation method.

ChainCatcher News, according to The Block and several other media outlets, crypto asset management company Grayscale has submitted multiple filings to the SEC, covering spot ETF proposals for Bitcoin Cash (BCH), Litecoin (LTC), and Hedera (HBAR): among them, LTC and BCH are filed in S-3 form with the intention of converting existing trusts into ETFs, while HBAR has submitted an S-1 registration and the exchange has simultaneously submitted a 19b-4 rule change application for listing. All of these products are pending SEC approval, and the progress related to HBAR has recently been postponed to November 12. Grayscale stated that this move aims to expand the coverage of spot crypto ETFs from Bitcoin and Ethereum to more mainstream assets; whether they can ultimately be listed still depends on the dual approval of the 19b-4 and registration filings.
