Recently, interest in bitcoin, a kind of digital cryptocurrency that can be paid in kind, has been rising, and bitcoin is a digital currency created by Satoshi Nakamoto in 2009. It consists of a structure in which there is no central device to manage. Instead, Bitcoin transactions are made by a distributed database based on a peer-to-peer network (P2P), and transactions are usually performed using a public key encryption algorithm.

As such, digital cryptocurrencies that can be paid in kind include Bitcoin, Litecoin, Darkcoin, Namecoin, Dogicoin, Ripple, etc. Thus, a book of transaction details is stored in the electronic wallet, and the ledger is sequentially connected according to blockization and hash transformation in a certain unit, and can be shared on the blockchain network in a verifiable form by hash comparison. These cryptocurrencies may currently be exemplified by Bitcoin, Litecoin, Darkcoin, Namecoin, Dogecoin, Ripple, and the like.

Individual blocks connected to such a block chain may be sequentially connected according to hash conversion, and may be configured in the form of a data packet including a plurality of information. For example, the information included in the block may be a transaction history in which the participants traded currency, and the hash value of the previous block, difficulty, nonce, and the like. Each block contains the hash value of the previous block, and the blocks connected in this way can form a single block chain containing the transfer details that occurred in chronological order.

When such a block chain network is formed, one transaction book can be shared through nodes connected to the network, and the transaction book can be preserved by the block chain verified and formed by a large number of unspecified nodes. Since such a transaction book is continuously shared, verified and preserved by all node terminals connected to the network, forgery and falsification of the transaction book is prevented by the majority of nodes wishing to maintain the transaction system.

In addition, the target of such an attack action such as hacking on the block chain network should be the transaction system itself composed of an unspecified number of nodes, not a specific terminal, and the action itself destroys the transaction system itself. Due to the low benefit value, the establishment of hacking itself can be prevented in advance, and therefore reliable decentralized transactions of cryptocurrencies can be established without separate central control.
