One of the most frequent questions asked about distributed censorship-circumvention systems is why the architecture must be made so complex when a simple dedicated server could deliver access. The answer lies in the fundamental weakness of any finite set of static IP addresses when confronted with modern blocking techniques.
Single-server and small-server deployments are easy to develop and maintain, yet they share one critical vulnerability: once an address enters a blocklist, service through that address stops. Discovery does not require deep packet inspection of every packet; it is enough to recognize characteristic traffic patterns and record the destination. When the number of addresses is limited, they can be identified and blocked sequentially.
Maintaining many servers does not solve the problem by itself. If a significant portion of the infrastructure belongs to the same provider or ASN, a single block can affect numerous nodes simultaneously. Moreover, any fixed list of addresses can be gradually updated by the blocking party as long as the list changes slowly.
The decisive difference in the distributed model is that user devices themselves become transport nodes. Clients form a mesh and can relay traffic for one another in a P2P manner similar to the original Skype architecture. Consequently, data transfer no longer depends on every user connecting to one of a small number of dedicated servers. The resulting network lacks a stable, enumerable list of addresses; its composition changes with the set of active participants.
Individual client nodes can still be discovered and blocked, yet the detected set constantly becomes outdated. Address blocking therefore turns from the relatively simple task of maintaining a server list into the continuous task of discovering a dynamic participant set.
A separate backbone network continues to exist, but its role is limited to trust, coordination, and providing exit points. It helps clients determine which configurations and nodes to trust and is not intended to replace the client mesh for transport.
Mesh operation does not eliminate the need for anti-DPI measures. Techniques such as uTLS ClientHello rotation and decoy traffic remain essential to prevent individual connections from being easily classified. The two layers address different problems: anti-DPI mechanisms make single connections harder to fingerprint, while the distributed architecture prevents blocking from being reduced to maintenance of a small, stable server list.
The approach carries tangible costs. When a device relays transit traffic it consumes its own bandwidth and battery, an especially noticeable burden on mobile clients. Operational safeguards are also required to prevent abuse of the relay mechanism and to account for devices that cannot sustain server-level loads. The result is a deliberate engineering trade-off: added system complexity is accepted in exchange for turning a static blocking task into a continuously evolving discovery problem.
