Tether is testing a new decentralized search engine designed to work without relying on a single central server, and its latest test involved distributing the full Wikipedia archive across 100 separate nodes.
Tether CEO Paolo Ardoino said the company’s peer-to-peer team is developing what he calls the “Unstoppable Search Engine.” The goal is to eventually run the system across thousands of nodes while keeping information available even if some parts of the network go offline.
In the latest test, the entire Wikipedia archive was spread across 100 nodes and remained searchable through the network. Ardoino shared a demonstration of the search interface on Sept. 8 and described the results as “insane.”
The project builds on Hypersearch, a decentralized search system Ardoino first revealed in April. Instead of keeping the search index and processing system under one central operator, the technology distributes them across multiple participants.
Tether says the system uses fault-tolerant structures so information can remain available even when individual nodes are unavailable. The company also sees the approach as a way to make search more resistant to censorship and reduce dependence on centralized infrastructure.
However, the search engine is still being developed. Tether has not announced when it will be available to the public or explained exactly how it plans to search and rank information from the wider internet.
Hypersearch uses distributed hash table technology, which allows information to be stored and found across different network participants without depending on one central directory.
The system is also connected to HyperDHT and other peer-to-peer technologies used by Tether and the Holepunch software ecosystem. Tether is currently looking for engineers with experience in distributed databases, peer-to-peer networking, search systems and related technologies.
The company’s move into decentralized search is part of a much larger push into peer-to-peer software.
Tether and Bitfinex have previously supported Holepunch and its encrypted communication app Keet, which allows users to make calls, send messages and transfer files through a distributed network.
Tether has also used similar technology in its Bitcoin mining projects. Its Mining OS was released as open-source software in February 2026, using encrypted peer-to-peer networking for mining operations ranging from individual setups to large facilities.
The company later introduced an open-source Mining Development Kit aimed at giving developers tools to control and monitor mining hardware through software.
Now, Tether is applying the same decentralized approach to search and information retrieval.
The Wikipedia test gives the company a way to see how the system performs with a huge collection of existing information. But several major questions remain, including how the system would search the wider web, how results would be ranked and how it would handle spam, false information and conflicting data across thousands of nodes.
Tether is also working on other decentralized technologies outside its stablecoin business.
The company has been developing QVAC, an artificial intelligence project focused on running AI models directly on users’ devices instead of relying heavily on centralized cloud services.
Its broader goal appears to be building software and infrastructure that can operate across distributed networks rather than depending on a single company, server or data center.
For now, the search engine remains in the testing stage. The latest demonstration shows that Tether has successfully distributed the full Wikipedia archive across 100 nodes, while the company works toward a system that could eventually operate across thousands of participants.
