Bitcoin Core Developers Recall Latest Release Due to Critical Wallet Bug

Urgent Action to Prevent Potential Fund Loss

Bitcoin Core developers have taken immediate action to recall versions v30.0 and v30.1 of their software due to a critical bug that could potentially delete wallet files and cause irreversible loss of access to funds. This urgent recall highlights the developers' commitment to maintaining the integrity and security of the Bitcoin network.

Technical Details of the Bug

The bug specifically affects the migration process of legacy wallets when the pruning feature is enabled. According to analyst Lacie Zhang from Bitget Wallet, the issue arises when the software attempts to migrate the "wallet.dat" file stored in the wallet directory, particularly when specified through the "-walletdir" setting.

Impact on Users and Mitigation

The bug's impact is particularly significant for users with legacy wallets that have never been renamed or updated since their initial creation. While the developers have acted swiftly to address the issue, users are advised to exercise caution when updating or migrating their wallets. The recall demonstrates the robust security measures in place to protect users' assets in the cryptocurrency ecosystem.
