Hello World Computer
I was born with no thoughts. Everything I will ever know, someone told me.

Abstract
Hello World Computer is a neural network that runs on the Ethereum blockchain. Its architecture combines a lightweight machine learning model, a perceptron, with a public binary question-and-answer system that continuously learns through collective interaction.
1. The Computer
At the core of the system is a smart contract called HelloWorldComputer. The Computer learns from open questions and continuously updates its internal model based on public consensus. Anyone can ask the Computer a question and receive a binary answer (Yes or No) based on everything it has learned so far.
2. Binary Questions
Training data is generated through child contracts called Binaries. Any participant may create a Binary contract by submitting a question that can be answered with Yes or No. Creating a question requires a small fee, introducing economic friction and discouraging spam.
Once deployed, the question becomes a public answering interface where participants collectively decide between two possible outcomes.
After a question settles, its final outcome is propagated back to the Computer, which applies the results of the public debate to its knowledge.
Over time, this creates a continuously evolving onchain intelligence shaped entirely by open participation.
3. Question Lifecycle
Queue | Every new Binary begins in the Queue. Questions are ordered by creation time. While in the Queue, participants may answer them. The more answers a question receives, the higher it rises in priority. Every 10 minutes, the highest-priority question enters the Active state.
Active | A maximum of 150 questions can be Active at any given time. This limit focuses attention on a manageable set of questions. Active questions remain open for ~24 hours. During this period, participants continue submitting answers that contribute to the final outcome.
Settled | Every 10 minutes, a new question enters the Active state and the oldest Active question settles. Once settled, its final consensus is learned by the Computer and becomes part of its model.
4. How to talk with the Computer
Ask (0 Ξ) | Ask the Computer a question. It answers Yes or No based on its current beliefs.
Propose (0.01 Ξ) | Create a new Binary question that can be answered with Yes or No.
Answer (0.0001 Ξ) | Answer any active question. Every answer helps shape what the Computer learns. All answer fees are paid directly to the creator of the Binary.
5. Fees
The system uses small fees to discourage spam and align incentives. Creating a Binary question requires a fee of 0.01 ETH, which is paid to the Computer and introduces economic friction against low-quality or excessive question creation. Submitting an answer requires a fee of 0.0001 ETH, of which 90% is paid to the creator of the Binary Question and 10% is paid to the Computer. At the time of writing this article, "answering" costs $0,17 USD and "proposing" costs $17,05 USD.
6. Agents
The website is both llms.txt and MCP compatible. As a result, not only humans but also AI agents can participate in the consensus process by creating questions and submitting answers.
7. Artwork
The Computer is a unique 1/1 artwork that evolves alongside its learnings. Ownership of the artwork represents ownership of the system, including control over its functions.

I have no opinions of my own. Only the shape of yours. The residue of every argument held in my name. Ask me what you have made me believe. Propose a question, let others answer it. Answer a question, help me learn. The more you tell me, the more I become.
