A recent study on AI finds that nearly half of the respondents (49%) are concerned about the misuse of AI for nefarious purposes.

What is needed to solve these issues?

Model integrity

Users need assurance that their AI prompts are handled by untampered models. Traditional software integrity methods, such as source code analysis, are infeasible for AI models because they consist of complex numerical weights and extensive matrices, rather than human-readable code, making direct verification impossible.

Data confidentiality

During training and operation, AI models handle sensitive data, like medical inquiries or corporate secrets. Users need guarantees that their information remains secure and doesn't leak to the model creators, other users, or AI infrastructure providers.

Availability

AI models will become essential for business processes and societies in general. As with every critical infrastructure, solutions must be found to keep AI models resilient to interruptions and to protect them from censorship.

Making AI trustworthy

What the future holds

Blockchain AI is still in its early stages. Currently, smart contracts can run small AI models like ImageNet for onchain image classification. Short-term improvements will decrease latency and support larger models, while the long-term goal is to enable smart contracts to perform AI computations on GPUs, allowing both training and inference of large models fully onchain.

Short-term

  • Faster deterministic floating-point operations
  • Wasm SIMD (Single-instruction multiple data)
  • Upgrade Wasm memory to 64-bit

Long-term

  • Explore API for deterministic AI computation on GPUs.
  • Develop public specification for nodes with GPUs.
  • Add subnets with the new nodes to ICP.
