Hello World Computer

Hello World Computer is a neural network that runs on the Ethereum blockchain and learns from public yes-or-no questions answered collectively by participants. Its architecture combines a lightweight perceptron model with a binary question-and-answer system, and anyone can ask it a question and receive a Yes or No answer based on what it has learned. Questions are created for a fee of 0.01 ETH and enter a queue, then become active for about 24 hours, with at most 150 active at once. Answers cost 0.0001 ETH, with 90% paid to the question's creator and 10% to the Computer. The article also says the website is compatible with llms.txt and MCP, so AI agents can participate too.
