Max Tannahill launches Dojo Bay to block server seizures
- Max Tannahill launched Dojo Bay to distribute Bitcoin node lookups after federal backend seizures.
- Volunteer server nodes operating across multiple countries prevent single enforcement points of failure.
- Cryptographic Bit47 signatures verify node identities so malicious server operators cannot trace wallet histories.
Federal domain seizures broke mobile privacy wallets overnight. When authorities shut down Samourai Wallet's central servers, thousands of users lost access to their funds. The outage exposed the core vulnerability of relying on centralized backends for mobile apps.
Max Tannahill designed Dojo Bay to fix that single point of failure. Speaking on Ungovernable Misfits, Tannahill explained how the open-source directory routes mobile users to independent, volunteer-operated nodes scattered across Mexico, Spain, and the UK. Running a full local node requires hardware and technical skills that most mobile users lack, making a distributed directory crucial for network access.
Distributing backends across multiple borders dilutes regional legal risks. No single court order can take down dozens of independent servers running across five continents.
Security remains the principal risk when connecting mobile wallets to third-party public nodes. Arbitrary node connections can leak extended public keys, enabling host operators to map a user's entire financial history. Dojo Bay mitigates this by requiring server operators to sign pairing credentials with Bit47 payment codes before joining the directory.
Users cryptographically verify those pairing signatures before establishing connections. Any tampered data provided by a compromised web host instantly fails signature checks. The entire system operates without central cloud databases, corporate domain registrars, or password authentication, utilizing Auth47 cryptographic challenges for administrative access instead.
System resiliency extends to the directory's distribution layer. The full Dojo Bay codebase is mirrorable over Tor onion routing, letting users download independent copies directly from active nodes with a single terminal command. Wallet software like Sentinel can query these signed directories directly, executing automated node failovers without manual configuration.
Cryptographic verification replaces institutional trust. Centralized wallet backends are officially obsolete.
