Crypto: Ethereum Developers Suggest Using Zk Tech To Anonymize AI Use
Ethereum co-founder Vitalik Buterin and the Ethereum Foundation’s head of AI have proposed a method to keep users’ AI API calls private while still allowing punishment for abuse.
Ethereum Foundation AI lead Davide Crapis and Ethereum co-founder Vitalik Buterin have proposed a way to use zero-knowledge proofs and other methods to ensure that a user’s interactions with large language models are private, while preventing spam and abuse.
“We need a system where a user can deposit funds once and make thousands of API calls anonymously, securely, and efficiently,” they said.
“The provider must be guaranteed payment and protection against spam, while the user must be guaranteed that their requests cannot be linked to their identity or to each other,” they added.
The duo proposes a system where users deposit funds into a smart contract and then make API calls without revealing their identity or linking requests, leveraging zero-knowledge proofs and rate-limit nullifiers for payments and anti-spam enforcement.
“A user deposits 100 USDC into a smart contract and makes 500 queries to a hosted LLM. The provider receives 500 valid, paid requests but cannot link them to the same depositor, or to each other, while the user’s prompts remain unlinkable to the user identity,” Crapis and Buterin said.
To deter scammers, illegal content generation, jailbreaking attempts, and other terms-of-service violations, Crapis and Buterin propose a dual-staking system.

If a user is caught trying to double-spend, their deposit can be claimed by anyone, including the server. However, users violating the terms of service will have their deposit sent to a burn address, and the slashing event is recorded on-chain.
“For example, a user might submit a prompt asking the model to generate instructions for building a weapon or to help them bypass security controls — requests that would violate many providers’ usage policies,” Crapis and Buterin said.
