ttceco / oak_random_service

This is an oracle service for the OAK token generation process. It generates a list of random numbers based on a seed value obtained from smart contracts and provides these numbers back to the smart contracts. This allows the smart contract to select winners in each token generation round.

OAK Random Service

OAK Random Service is a crucial component in the process of OAK generation. It ensures that the OAK generation process is both fair and transparent. Specifically, this service is designed to randomly select tickets when the number of tickets for a given day surpasses the one-day limit.

How it Works

1. Seed Generation: Call the smart contract to generate a seed. This can be done only once per round by any user.
2. Random Data Generation: With the seed, obtain random data off-chain using any compatible program. For instance, with Python, once the data is generated, check if your tickets are part of the selection.
3. Admin Input: Admins input the random data to the smart contract in batches. After all entries, you can verify your ticket's status either on the smart contract or via the OAK app.

Running the Checker Script

To check the ticket status with our Python script:

Prerequisites:

Ensure Python3 and pip3 are installed:

sudo apt-get update
sudo apt install python3-pip

Install the required Python packages:

pip3 install web3

In case of any issues installing web3:

python -m pip install --user cython
python -m pip install --user cytoolz
python -m pip install --user eth-brownie

Execution:

Run the script:

python3 oak_random_checking.py
