A vision initiated by ORA
In this section, we provide a list of educational tutorials, that will help you get started with Onchain AI Oracle (OAO).
ai/fi = AI + DeFi
Permissionless Technology for AI x Crypto
Usage Guide for Anyone to Use Onchain AI Directly as User
Initial Model Offering

ssh-keygen -t rsa -b 4096 -C "[email protected]"docker build -t ubuntu-opml-dev .git clone [email protected]:OPML-Labs/mlgo.gitcd mlgopip install -r requirements.txtcd examples/mnistpython3 convert-h5-to-ggml.py models/mnist/mnist-small.state_dictcd ../mnist_mips && ./build.sh# How to run instructions:
# 1. Generate ssh command: ssh-keygen -t rsa -b 4096 -C "[email protected]"
# - Save the key in local repo where Dockerfile is placed as id_rsa
# - Add the public key to the GitHub account
# 2. Build docker image: docker build -t ubuntu-opml-dev .
# 3. Run the hardhat: docker run -it --rm --name ubuntu-opml-dev-container ubuntu-opml-dev bash -c "npx hardhat node"
# 4. Run the challange script on the same container: docker exec -it ubuntu-opml-dev-container bash -c "./demo/challenge_simple.sh"
