Helius CEO: Anthropic Is Using Cryptographic Technology First Adopted by Zcash

According to 深潮 TechFlow, on November 3, Mert, CEO of Solana infrastructure company Helius, stated in a post that Anthropic and Claude are using similar cryptographic technology first adopted globally by Zcash.

According to Anthropic's official website, Anthropic open-sourced the research prototype FlashProve on November 2, using zero-knowledge proofs (zkSNARK) to achieve provable inference, meaning model providers can prove that a response was indeed generated by their stated model without revealing model weights.

According to the description, providers first publish a commitment to the model weights offline, then generate a proof for each request, and users can verify it on a standard CPU in a few seconds. Taking Llama 4 Maverick with 400 billion parameters as an example, a single H100 can generate proofs for about 110 tokens per second, and the proof for a 1024-token request is about 19 MB. The system was optimized with Claude's participation, and its security properties are formally described using Lean.

Anthropic stated that the current proof cost is approximately 70–95 times the GPU time of standard inference, and it remains a research prototype, not yet production-ready.
