The blockchain infrastructure company Gattaca announced the launch of the open-source Ethereum consensus client Silver. The company operates the Ethereum block builder Titan Builder and the relay Titan Relay. Gattaca stated that Silver was built from scratch, aiming to support shorter time slots and post-quantum security while maintaining decentralization, censorship resistance, privacy, and security. Currently, Silver is in the alpha stage, with audits and final testing yet to be completed.Gattaca claims that Silver's state transition function has a p99 latency of less than 10 milliseconds, approximately 10 times faster than other clients. During the mainnet window from October 17 to 20, 2026, Silver, Prysm, Lighthouse, and Grandine processed the same 20,300 canonical blocks. The median block processing latency for Silver was 6.5 milliseconds, with a p99 of 9.5 milliseconds, and the slowest block in the sample was 17.8 milliseconds; the second-lowest median was 33.5 milliseconds, and the second-lowest p99 was 91 milliseconds. All four clients operated as supernodes, subscribing to all 64 proof subnets and hosting all 128 data columns, with the executing client being ethrex v29.0.1.The above comparison used consensus processing metrics available for each client, excluding execution client processing time. Silver is based on Gattaca's Flux framework, using six threads bound to CPU cores for parallel processing, and comes with a low-latency peer-to-peer network, state hash library, formally verified BLS and KZG cryptographic libraries, and a node cluster for penalty protection. In another comparison, supernodes needed to verify about 32 times the proofs and about 16 times the KZG unit proofs relative to the default configuration, with block processing latency and resident memory still within a similar range.

According to market news combined with on-chain data, it is suspected that Binance's Ethereum hot wallet has encountered a large abnormal outflow, involving over 60 types of tokens, with an asset scale of approximately 2.53 billion USD.Currently, this news has not been officially confirmed, and the specific situation awaits further verification.

Axis Robotics issued a statement regarding the massive sell-off of AXIS tokens from October 28 to 29, stating that no team or investor tokens were sold. The team, investors, and other locked allocations total 835 million AXIS, accounting for 83.5% of the total supply, and remain in a custody contract co-managed with Binance, with no tokens transferred out, and they will not be unlocked before the end of the 12-month lock-up period.The project party stated that the tokens sold this time came from a portion of the ecological allocation in the initial circulating supply, which was originally delivered through a single over-the-counter (OTC) trading counterparty, and the relevant written agreement includes lock-up terms. The project party believes that the trading model indicates that this counterparty may sell the tokens on the open market, which, if true, would violate the agreement. They have currently suspended further transactions with this counterparty and are reviewing the agreement with legal counsel to seek remedies; the remaining ecological tokens will only be distributed through on-chain custody mechanisms in the future.ChainCatcher previously reported that, according to on-chain detective ZachXBT, insiders from Axis Robotics (AXIS) obtained over 76 million AXIS tokens (worth over 12 million USD) from a multi-signature wallet, which were then sold off through a DEX, with some tokens transferred to Bitget exchange. As a result, the AXIS price plummeted by 40% in the past 24 hours.One insider sold 42 million AXIS tokens and currently holds over 5.04 million USDC across their 8 wallet addresses.

According to the Digital Currency Research Society, on October 27, Beijing Bank released a public tender announcement for the procurement project of firewall equipment for digital currency business in 2026 through the official centralized procurement management system. Along with the previously announced procurement projects for IPS, encryption machines, WAF, SSL, signature devices, etc., the bank has officially launched a centralized upgrade of the full-chain security infrastructure for digital renminbi business, covering core security nodes such as intrusion defense, encrypted transmission, web application protection, and identity signing.In April of this year, Beijing Bank became a newly added operational institution for digital renminbi business and connected to the central bank's digital renminbi system. In August, the central bank added 8 more operational institutions, expanding the total to 30. Previously, several newly added operational institutions, such as Huishang Bank, Hangzhou Bank, and Guangxi Beibu Gulf Bank, had initiated tenders for core digital currency systems worth tens of millions. The report pointed out that Beijing Bank's inclusion of various security devices such as firewalls and encryption machines in centralized procurement is a proactive security layout to adapt to the new features of digital renminbi, such as high-concurrency transactions and programmable smart contracts.

CryptoQuant analyst BaykusCharts stated that Binance's Ethereum open interest is currently about 5.8 billion USD, which is about half of last summer's peak of over 12 billion USD. On the surface, this looks like large-scale deleveraging, but open interest is denominated in USD, and the ETH price has also dropped by about half during the same period. When converted to ETH, the current open interest is about 2.5 million ETH, close to the peak of about 2.5 million ETH. Therefore, the decline is primarily driven by price rather than traders closing their positions.In terms of funding rates, the significant positive premiums seen in early 2021 and early 2024 have disappeared. After experiencing several periods of negative funding rates this year, it is currently just slightly above zero, with both long and short positions not overly crowded, and longs are not paying significant premiums. Analysis suggests that there is still a large amount of leveraged ETH exposure in the market, but there is a lack of strong directional confidence. This limits the risk of a one-sided liquidation chain reaction, but it also means that any decisive breakthrough in either direction could accelerate quickly. The key signals are: a price increase and a sharp rise in funding rates indicate long crowding; a price decrease and an increase in open interest indicate a growth in short positions.
