According to @1HowardWu, delegable proving schemes allow outsourcing computation without leaking witness data, so the prover performs the work without seeing private inputs (source: @1HowardWu on X, Nov 10, 2025). The author states that privacy-preserving delegation is built into the Varuna proof system, addressing concerns about data exposure during outsourced proving (source: @1HowardWu on X, Nov 10, 2025). The author also notes the capability is not widely deployed yet, indicating limited current availability for production use (source: @1HowardWu on X, Nov 10, 2025). For traders, the stated ability to outsource proving without input leakage reduces data exposure risk in outsourced ZK workflows, a factor to watch for adoption signals once deployments expand (source: @1HowardWu on X, Nov 10, 2025). Monitor announcements of production rollouts or integrations of Varuna’s privacy-preserving delegation to gauge potential traction across ZK applications and proving marketplaces (source: @1HowardWu on X, Nov 10, 2025).
