We provide a method for managing theft and loss of various IDs to make it possible.

In the present invention, an independent environment for executing smart contracts can be created so that each function can be designed separately for smooth function change and efficient transaction processing.

In addition, the smart contract described in the present invention is a computer protocol for establishing, verifying, and executing a specific contract by itself in a situation that satisfies the condition when the user inputs a desired condition by allowing multiple conditions to be set. Transactions are programmed to execute automatically without intermediary intervention.

That is, as an automated contract system, it is widely used for personal identification, ownership authentication, transfer of ownership, inheritance, gift, purchase of goods, product guarantee, etc. Recently, it is used in connection with the Internet of Things. In smart contracts, transactions are automatically established according to conditions, so it is possible to prevent forgery and falsification damage by middle managers.

In addition, because transaction information records are preserved, malicious acts such as contract forgery*?* accident record manipulation, etc. can be prevented, thereby reducing credit risk and counterparty risk.

Here, the structure of the smart contract is simple. It is executed when the conditions of the contract made between the parties are satisfied, and these transaction clauses can be recorded in a script in the block chain, which is also shared by all participants.

Blockchain is a technology that records and manages the ledger that records data information jointly by electronic devices participating in the network by distributing it to a P2P network rather than a central server of a specific institution.

In the existing system, there was an arbitrary central administrator, and the role of confirming and clearing data between both parties and keeping transaction records, but the blockchain ultimately makes the role of such central administrator unnecessary, resulting in low system infrastructure costs and There is also an advantage in that data integrity increases as the number of participating electronic devices increases.

In the present invention, a transaction is a set of operations constituting one logical unit of work, and includes atomicity (all tasks are completed or canceled as an inseparable unit), consistency (used All data is consistent), Isolation (data being accessed can see the state before and after the transaction is completed from another transaction, but cannot see the intermediate data of the transaction) , has durability (when a transaction is normally terminated, the result is permanently applied to the system).
