According to The Defiant, the number of active addresses for the Ethereum Layer 2 scaling solution Arbitrum rose to 1.09 million on October 28, setting a new 30-day high.Data shows that the increase in the number of transactions on that day was significantly lower than the increase in active addresses, while the fees paid by users remained roughly at the median level of the previous week.

The cryptographic security vulnerability of the Indian certificate authority eMudhra affects the Ethereum clients Teku and Besu. Researchers found that the private keys of 8 intermediate certificate authorities under eMudhra could potentially be deduced due to insufficient randomness, allowing attackers to forge certificates and trick unpatched software into trusting malicious services.Teku has released version 26.1.3, and Besu has released version 26.1.2, both of which have removed trust in the relevant certificates from their Docker images. If an attacker performs a man-in-the-middle attack, they could trick some validators into sending block fee rewards to the attacker's address; the risk may be higher under specific configurations using external signers. The Teku team stated that the default configuration of the Ethereum mainnet Teku node is not affected, and no action is required, with no reports of the vulnerability being exploited so far.For operators running Teku or Besu directly on the host without using Docker, simply updating the client may not be sufficient; they also need to manually update Java and its trusted certificate list. Operators still using the no longer maintained Java 26 will need to migrate to Java 25.

EIP-8450 proposal update, intended to introduce a quantum-resistant public key registration mechanism for Ethereum validators, using a hash-based cryptographic scheme, including leanXMSS keys and VRF tree roots.The update clarifies that the registration and replacement of quantum-resistant keys are authorized by BLS signature keys, and sets a replacement delay of at least one Epoch and a replay protection mechanism; this proposal is currently still in the Draft stage and has not yet been deployed.

The decentralized liquidity staking protocol Diva Staking announced on social media that it will shut down the project and will not launch the mainnet. The official statement said that this decision was made after thorough discussion and apologized to the early stakers who had pre-deposited in the vault, stating that related deposits can be withdrawn through Enzyme without further waiting.The official statement mentioned that the team has been operating for about two and a half years without income or salary since the funds were exhausted in mid-2024, with three members pushing the project forward. Diva went live on the Hoodi testnet earlier this summer and has been running stably for about four months without any issues, but failed to gain support from large institutions for the mainnet launch. The three-member team also could not bear the costs of a new round of audits and mainnet operations, thus choosing to wind down rather than risk launching.The announcement also stated that the demand structure for LST has changed after the Shanghai upgrade. As of the end of June this year, BitMine, Coinbase, and Binance together accounted for about 30% of the total staked ETH, with approximately 11.5%, 10.9%, and 7.9% respectively, which is comparable to the concentration when the market was concerned about Lido's share being close to one-third. The official also congratulated Lido for advancing Simple DVT and opening up to independent stakers.

The Ethereum Foundation forwarded tweets related to the privacy tool Kohaku, expressing support for the development of privacy-protecting wallet tools. In response to the attacks and exploits that occurred over the past week, the Ethereum Foundation pointed out that privacy and security should not be viewed as mutually exclusive goals. Setting privacy protection as a default feature helps reduce the risk of attackers exploiting users' on-chain historical records to carry out attacks.According to developer Jordan Enev, the Kohaku team is working to make privacy protection a standard feature of Ethereum. Currently, its SDK has integrated privacy protocols such as Railgun, Privacy Pools, and Tornado Cash, with development progress becoming increasingly mature, and they are calling for more wallets to promote related integrations.

ENSv2 officially launched on the Ethereum mainnet, introducing a layered registry and a more refined permission model, supporting community and institutional custom subdomain issuance rules and partitioned authorization management. The new version also updates the domain resolution method and supports record link sharing, while launching the ENS App for ordinary users and the ENS Explorer for developers.ENS states that its ecosystem currently supports over 36 million domain names, covering more than 600 applications; existing .eth domain names do not need to be re-registered and can voluntarily upgrade to ENSv2 within the ENS App starting today.

According to CoinDesk, Ethereum developers have fixed a vulnerability in the Glamsterdam upgrade that could allow operators to withdraw ETH intended for new validators from the staking service. The fix changed the handling rules for validator deposits and was merged on Monday, after developers had rejected the modification a week earlier.Researcher avsetsin discovered that if an operator first registers as a builder with a specific public key, and the staking service subsequently deposits ETH using the same key to activate the validator, the draft rules would credit both deposits to the builder. Avsetsin stated that this is a conditional code discovery and not a confirmed real-time exploit; existing checks can prevent the attack, and there are currently no reports of losses. The new rules treat deposits as sorted by withdrawal receipts, ensuring that validator deposits still belong to the validators.Glamsterdam has been running on the Sepolia testnet, but the launch on the Hoodi testnet has been delayed, with a new date to be determined before the mainnet launch.

ARK Invest's Director of Digital Asset Research, Lorenzo Valente, stated that the number of addresses holding stablecoins has surpassed 300 million for the first time. The Ethereum ecosystem currently accounts for 37% of all stablecoin holding addresses, up from 29% two years ago, with approximately three-quarters coming from L2. He believes that the strategy of expanding adoption through L2 is proving effective and expects tokenized stocks to develop along the same path.Valente also mentioned that if one were to illustrate the dominance of EVM, EVM-compatible chains hold about 94% of stablecoin addresses. It took 8 years for the number of stablecoin holding addresses to reach 300 million, and he anticipates that it could reach 1 billion wallets within 18 months, faster than the existing trend.
