Could a Folding@home-style P2P network of idle GPUs collectively run and train LLMs?

lenicalicious · reddit · 2026-11-03

A Reddit user proposes an open question: build a Folding@home-style decentralized peer-to-peer network that pools the world's idle compute — gaming PCs, servers, phones — to collectively run and even train large LLMs.

The vision: no central servers, subscriptions, crypto tokens, or corporate ownership; contributors donate spare resources in exchange for access; latency is acceptable if responses are slower; anonymity is architectural (no accounts, no IP logging, no centralized histories). The author acknowledges prior art like Petals and known obstacles — synchronization, malicious nodes, computation verification — but argues these may be underexplored engineering problems rather than fundamental limits. They invite distributed-systems and LLM-architecture experts to weigh in.
