🚀 Dogecoin Vulnerability Exposes Node Weaknesses

According to PANews, a recent vulnerability attack has significantly impacted Dogecoin's node structure. The flaw, known as 'Dogereaper,' was exploited by Sequentia developer Andreas Kohl, who managed to crash 69% of Dogecoin nodes using an old laptop from El Salvador. Despite the severe impact on Dogecoin nodes, the situation could have been worse. The vulnerability was disclosed by ecash developer Tobias Ruck and another developer, Roqqit.

Tobias Ruck revealed that he first discovered the vulnerability while developing Doged, an alternative to Dogecoin Core. During code testing for their alternative software, they identified an unpatched segmentation fault in the original code. Ruck emphasized the importance of network security, stating, 'We do not tolerate node crashes, and we have put in a lot of effort to ensure network safety. This attack could have been more severe, but all major stakeholders, such as miners and exchanges, had already patched the issue before the attack occurred. This highlights the importance of our cautious approach.'

🚀 Bitcoin Core Identifies Wallet Migration Error in Latest Versions

According to Foresight News, Bitcoin Core has reported a wallet migration error in its 30.0 and 30.1 versions. In rare instances, migrating older BDB wallets may result in the deletion of all wallet files on the same node. This issue could lead to the loss of funds if these wallets are not backed up.

Bitcoin Core clarified that only the migration process of older wallets is affected. All other functionalities remain unaffected. Users can continue to use Bitcoin Core, including existing wallets and running nodes without wallets.

🚀 Understanding the Role of Public and Private Keys in Digital Transactions

Crypto KOL 陈剑Jason posted on X. In a digital transaction scenario, the public key is akin to a phone number displayed in a lost and found notice, pointing to wallet assets visible to the public key owner. The private key, comparable to the owner's ID number, is required to initiate a signature on the public key, enabling the completion of the call process. The individual who finds the wallet acts as a node, verifying the correctness of the private key signature and facilitating the wallet transfer. Once the transaction is packaged, the owner retrieves a 100-unit reward from the wallet, which serves as Gas for the node.

🚀 Optimism to Cease Support for op-geth and op-program by 2026

Optimism has announced plans to discontinue support for op-geth and op-program by May 31, 2026. According to BlockBeats, while security patches and critical vulnerability fixes will continue to be released, new feature development, including the upcoming Karst hard fork, will be exclusively conducted on op-reth.

The fault proof program of op-program will be migrated to kona-client, with current deployments expected to remain operational until the Karst hard fork. Chain operators must complete the migration by the time of the Karst hard fork, as chains still running op-geth will be unable to follow the main chain.

Cannon-kona can operate within the existing op-node environment without the need for kona-node, which is an optional component. Node operators are advised to migrate to op-reth promptly to maintain network compatibility and access new feature support.
