Upgrading to Majora v3

In 2025 we redesigned Majora and released version 3. Compared with v2, the new architecture brings the following changes and advantages.

Refocused Priorities

Majora started as a solution for aggregating mobile devices into a proxy pool, where endpoints were often short-lived. Years of field experience showed that most customers actually build pools from VPS dial-up servers. As a result:

• The product now emphasizes deterministic endpoint deployment and configuration on VPS nodes.
• The Android app no longer escalates via shizhuku to toggle airplane mode. Root access is required to perform mobile redial.
• The “vendor” concept was removed; customers who need supplier-level settlement can calculate it from endpoint billing data.
• Deployment on Linux is simpler and more stable.

Protocol Enhancements

Majora v3 introduces a new proprietary protocol to address shortcomings in v2:

• Carefully designed message structures to avoid waste and ambiguity.
• Payload encryption at the protocol layer to reduce the risk of corporate firewalls flagging traffic.
• Shared-memory forwarding handles that minimize GC pressure and improve throughput.
• End-to-end tracing built into the protocol, which greatly improves debugging and observability.
• Semantic clarity: features that used to rely on ad-hoc extensions are now first-class protocol fields.
• Remote control operations (redial, shell execution, etc.) are standardized for better reliability.
• Added pty support so Linux endpoints can be managed via a web terminal.
• Java endpoints now support proxy chaining, making it easy to expose internal IP pools with built-in NAT traversal.

Composable Pools

In Majora v2, the distinction between the global pool and per-user pools made it hard to combine endpoints. In v3, pools and nodes are clearly separated: create any number of pools and assign arbitrary endpoints to them, assembling the exact topology you need.

Performance & Security

Majora v2 was tuned for hundreds of users and around ten thousand concurrent endpoints. Majora v3 reworks memory management and metrics to support:

• Tens of thousands of users.
• Hundreds of thousands of online endpoints (and even more on high-end multi-core servers with large memory pools).

These improvements deliver better scalability without sacrificing stability, while also tightening the overall security posture.
