The present disclosure relates to a distributed computing resource sharing system, and more specifically, based on a blockchain supporting smart contract, security on a resource sharing system to share distributed computing resources that can be used for machine learning. It's about communication.

In recent years, interest in artificial intelligence research based on machine learning is increasing. There is a high expectation that artificial intelligence based on machine learning will advance the future of mankind to a different level than before. Artificial intelligence research based on such machine learning basically has three essential elements: hardware resources that can support large amounts of computation, learning data that can be used for machine learning, and machine learning models (algorithms). By the way, as is well known, some big companies, such as Facebook, Amazon, Google, Microsoft, etc., each have their own monopoly for the above AI research, and individual researchers or small companies in relatively poor environments. They are being deprived of the opportunity to participate in AI research, which raises concerns that AI and the resulting developmental byproducts will be the property of these giants.

Meanwhile, since Satoshi Nakamoto introduced blockchain technology to the world through cryptocurrency bitcoin in 2009, interest in various types of cryptocurrencies and the blockchain technology supporting them has been getting hotter. Blockchain technology enables transactions based on a decentralized decentralized shared ledger method, providing high openness, reliability, transparency, and interactivity, and its applicability in various fields is being investigated. In particular, new blockchain technologies such as Ethereum following Bitcoin support smart contracts, that is, digital contract functions that specify the terms of the contract on the blockchain and automatically execute the contract contents when the conditions are met. , Application of such blockchain technology is being attempted in more various industries.

By providing data transmission and reception on the blockchain as a transmission / reception method of a public key infrastructure, a safe and low-load communication method is used. There are various types of cryptographic algorithms based on public key infrastructure, but 'Elliptic Curve Cryptographic Algorithm (ECC)' is mainly used in blockchain. The elliptic curve cryptographic algorithm is simply an 'algorithm that generates a corresponding public key using an elliptic curve when a specific secret key is input'. This is of course also a public key infrastructure, so it is powerful in that it is not possible to know what the original secret key was with the public key.
