Bitcoin Core Contributor Peter Todd Joins MARA Foundation as Chief Maintainer of Slipstream

Techub News reports that the MARA Foundation has announced that Bitcoin Core contributor Peter Todd has joined as the chief maintainer of its private Bitcoin mempool service Slipstream, responsible for the development and operation of the service. Slipstream allows users to bypass Bitcoin's public peer-to-peer network and send transactions directly to MARA Pool, keeping transaction information private before block confirmation. The service was previously used to support research projects such as Quantum Safe Bitcoin and Binohash. (WuBlockchain)

Bitcoin Core releases v31.0, introducing cluster mempool and enhancing private transaction broadcast

Techub News reports that Bitcoin Core has released version v31.0. The core of this update lies in the introduction of the "cluster mempool" design. This mechanism reorganizes related transactions into clusters not exceeding 64 transactions or 101 KB in size, enabling nodes to more precisely evaluate the overall value of transaction groups based on the fee rate diagram. This optimizes block packaging efficiency and refines the logic for RBF and CPFP. Furthermore, the new version significantly enhances privacy features, supporting users in broadcasting transactions privately via the Tor or I2P networks, effectively hiding the transaction initiator's IP address and geographical location. While ordinary transfer users are less affected, users of the Lightning Network or complex wallet services may notice significant changes in transaction acceptance rules.

Bitcoin Core: Wallet migration vulnerability exists in old wallet migration for versions 30.0 and 30.1

Techub News reports that Bitcoin Core Project posted on X, stating that Bitcoin Core 30.0 and 30.1 may, in very rare cases, delete all wallet files on the same node during the legacy (BDB) wallet migration process. If not backed up, this could lead to loss of funds. The fix will be released with Bitcoin Core 30.2. Until then, it is not recommended to use 30.0 or 30.1 for legacy wallet migration. Apart from the migration process, other functions are unaffected, and node operation and existing wallets can be used normally.

Bitcoin Core releases v30, increasing OP_RETURN data limit to 100,000 bytes

Techub News, according to Cointelegraph, Bitcoin Core developers have released version 30. The core changes include: introducing optional encrypted connections between nodes to enhance privacy protection, and increasing the OP_RETURN data limit in Bitcoin Core software from 80 bytes to 100,000 bytes, significantly expanding the amount of non-financial data that can be embedded in Bitcoin transactions. Although this update also includes bug fixes, performance optimizations, and fee rate adjustments, the community is divided due to the substantial increase in the OP_RETURN data limit. In particular, Bitcoin purists argue that the network should only be used for financial transactions.
