In recent years, interest in artificial intelligence research based on machine learning is increasing. There is widespread expectation that artificial intelligence based on machine learning will advance humanity's future to a different level than before. Artificial intelligence research based on machine learning basically has three essential elements: hardware resources that can support a large amount of computation, training data that can be used for machine learning, and machine learning models (algorithms). However, as is well known, some large companies, including Facebook, Amazon, Google, Microsoft, etc., monopolize each element for the above artificial intelligence research in their own way, and individual researchers or small companies in a relatively poor environment They are deprived of the opportunity to participate in artificial intelligence research, which is raising concerns that artificial intelligence and its various development by-products will become 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 that supports them has been increasing. Blockchain technology, in that it enables transactions based on a decentralized distributed shared ledger method, and provides high openness, reliability, transparency, and interactivity, and its applicability in various fields is being examined. In particular, new blockchain technologies such as Ethereum following Bitcoin support a smart contract, that is, a digital contract function that specifies contract conditions on the blockchain and automatically executes the contract contents when those conditions are met. , Application of such blockchain technology is being attempted in a wider variety of industries.

By providing data transmission and reception on the blockchain as a transmission/reception method of a public key infrastructure, a secure and low-cost communication method is being used. There are various types of encryption algorithms based on public key infrastructure, but the'elliptic curve encryption algorithm (ECC)' is mainly used in the blockchain. The elliptic curve encryption algorithm is, in simple terms,'an algorithm that generates a corresponding public key by using an elliptic curve when a specific secret key is input'. Of course, this is also a public key-based structure, so it is powerful in that you cannot know what the original secret key was with the public key.
