Subscription service method using blockchain-based smart contract {SUBSCRIPTION METHOD USING SMART CONTRACT BASED BLOCK CHAIN}

The present invention relates to a subscription service method using a blockchain-based smart contract.

Blockchain is a data recording technology based on P2P technology, and anyone is the subject of data storage and management and records the same information, respectively.

Here, the "block" of the block chain refers to a data storage unit, and is different from the meaning of the "block" of the file system as the minimum space in which one file can be allocated on the disk.

Blockchain technology does not store data in units of files based on the file system, but stores data in units of blocks in a distributed database environment.

Blockchain technology provides data integrity and persistence by synchronizing the records of blocks in which the same data is stored between nodes, which are the storage subjects of the block.

In addition, since the technology of the blockchain can be applied to general-purpose computer equipment, it provides cost-saving construction without expensive hardware and software equipment.

On the other hand, a subscription service is gaining great popularity recently, and the subscription service is a regular delivery service that'subscribes' to products or services at a fixed monthly fee.

The subscription service has the advantage of eliminating waste of resources and enabling efficient cost management because consumer consumption cycles are scheduled.

First, when explaining smart contracts, smart contracts refer to program code that can execute and execute contracts or negotiations using blockchain technology.

Thus, the entire process can be automated by program code to supplement or replace legal contracts.

The virtual currency storage function of the existing blockchain can be programmed in various forms.

Among the multiple cryptocurrencies, ethereum is a blockchain system that can execute smart contracts, and it can provide a global platform through EVM (Ethereum Virtual Machine).

Developers can execute smart contracts through programming and manage digital assets such as virtual currency.

Here, Ethereum was developed to use a platform that records various information such as SNS, e-mail, and electronic voting to overcome the fact that negotiations are not well conducted due to the structural problem of the Bitcoin network.

Ethereum can provide account management, currency generation and mining, and can use Distributed Applictaion (dApp) that can run applications on smart contracts and EVMs.

Nick Szabo, the first creator of smart contracts, defined smart contracts as a highly developed automatic contract execution method between machines in an unreliable computer networking environment, and various decentralized applications such as real estate contracts, online voting and healthcare on the blockchain. The platform has been extended to enable development.

Currently, the technology that focuses most in the second-generation blockchain is smart contract.

Even in Bitcoin, smart contracts were possible, but only if conditional statements were available, so there were restrictions on creating desired contracts.

On the other hand, Ethereum, well-known as a smart contract, can provide Turing completeness, so it can support even programming on a computer, so it is possible to program various types of transactions or contracts.

Existing contracts included legal language in documents printed by legal experts and were highly dependent on third parties.

In addition, traditional contracts are time consuming, and when disputes arise, they must rely on the judicial system, which is costly and time consuming.

However, the smart contract of the blockchain can be written by a computer programmer through a digital language to define the rules and results in the same way as specifying the obligations, benefits and penalties of the contracting party in the existing traditional contract, and is developed by programming. It has the advantage that the contract can be enforced by the system.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
