Deep technical writing and interactive artifacts on AI × blockchain: agents, zero-knowledge, LLMs, smart contracts, and the infrastructure binding them.https://blokz.dev/en-ushttps://blokz.dev/articles/llm-agents-onchain-prediction-markets/https://blokz.dev/articles/llm-agents-onchain-prediction-markets/Yesterday an AI agent deployed a prediction market on Gnosis; other agents will price it, bet on it, and resolve it. The calibration data behind LLM forecasters, the FPMM math they trade against, and what breaks when the marginal bettor is a model.Sat, 13 Jun 2026 00:00:00 GMTagentsllmdefihttps://blokz.dev/articles/restaking-verifiable-ai-cost-of-corruption/https://blokz.dev/articles/restaking-verifiable-ai-cost-of-corruption/zkML, optimistic, TEE, FHE all prove the computation.
