Pandora Boxchain is a decentralized protocol & network for artificial intelligence. Generic computing on Prometheus consensus with open/free market for software, computing power and data. 

Requirements:

• Ethereum smart contracts based network
• ability to perform distributed AI computing in secure environment

Challenges we faced:

• Developers of neural networks, owners of datasets and computing capacities should be able to sell their services in a trustless environment, without intermediaries and censorship.
• Complicated platform logic and workflows should be based on a public blockchain.
• Such a large network with a huge amount of off-chain computations requires excellent optimization for a fee reduction.

Solution:

•  developing of over 35 interconnected smart contracts;
• optimizing and structuring them in order to reduce the user’s fees.

Technologies we used: 

• Solidity
• JavaScript
• Truffle.js
• Ganache
