Description

Apparatus and method for approving deposit of cryptocurrency

The present invention relates to an apparatus and a method for approving deposit of a cryptocurrency exchange.

Bitcoin, a cryptocurrency and cryptocurrency that appeared in the world in 2009, not only showed high demand in the market by shaking the definition of currency, but also had a ripple effect of applying blockchain to existing services. Satoshi Nakamoto, the founder of Bitcoin, proposed a method of combining cryptography and network technology to record and verify currency issuance and transaction history on a peer-to-peer distributed network at the same time, which is a distributed ledger called Blockchain ( distributed ledger) technology. Bitcoin is the first use case to demonstrate that blockchain technology actually works. The market cap of global cryptocurrency (virtual currency) reached $ 150B in August 2017. In addition, in August 2017, Bitcoin achieved a global daily trading volume of KRW 2,600 billion, Ethereum of KRW 900 billion, and Ripple of KRW 1.8 trillion. As of November 2018, there are more than 1,000 cryptocurrencies being traded.

Cryptocurrency exchange refers to a market place that trades cryptocurrency held by a specific user with fiat currency or other cryptocurrency. Currently, representative cryptocurrency exchanges include Bitumb, Upbit, Kobit, Coinone, and Upxide in Korea, and bitFlyer, Quoine, Coincheck in Japan, etc. There are BTCChina, OKCoin, gate.io, KuCoin of China and Hong Kong, bitMEX, Bittrex, Coinbase, Kraken, deyMEX of USA, Binance, Bitfinex, Bitstamp, HitBTC of Europe. Cryptocurrency exchanges are on the rise worldwide, and as of March 2017, you can trade cryptocurrencies in 152 exchanges in 76 currencies.

In these cryptocurrency exchanges, when performing cryptocurrency deposits and withdrawals such as coins and tokens, cryptocurrency deposits and withdrawals are performed based on the confirmation of transactions that include state change information between the user account address of the public blockchain and the account address of the exchange. . At this time, according to the creation or distribution of the transaction, the user does not immediately perform the deposit and withdrawal of cryptocurrency, but since the withdrawal of the cryptocurrency is performed based on the confirmation of the transaction, there is a problem that the user's cryptocurrency deposit and withdrawal must be delayed considerably. . This is because the stability of a transaction improves as blocks accumulate after the creation and distribution of a specific transaction.

The transaction confirmation means, for example, in order to transfer the bitcoin of the A address to the B address, it creates a transfer transaction (Transaction) and signs it with its own 'private key' to propagate it to the network. When the transaction is stored in the queue of each node's memory, the stored transaction is propagated after the miner receives it, inserts it into the block it mines and issues, and then propagates it. As such, if a new block is additionally formed after the transaction is confirmed and connected to the previous blockchain with a blockhead hash value, the number of confirmations becomes 2 or more. Each cryptocurrency exchange pre-sets the number of such confirmations and approves or confirms the deposit.

Accordingly, for example, the coin deposit and withdrawal from the A exchange to the B exchange proceeds to the next step. The first stage is the withdrawal approval step of the A exchange, and in order to transfer the coin of the A exchange to the B exchange, the withdrawal approval of the A exchange must first be performed. In exchange A, if financial fraud such as voice phishing is suspected, exchange A will refuse to approve the withdrawal. The second stage is the blockchain network approval (confirmation) stage, and when the withdrawal approval is completed at the A exchange, the coin is sent to the blockchain network to receive confirmation. At this time, if the fee to be paid (GAS in the case of Ethereum) is low, the approval may be delayed or canceled if the miner evades approval. The third step is an approval step for depositing B exchanges, and approval is automatically performed when the number of confirmations for deposit approval is satisfied at the exchange to be deposited. The number of confirmations required for approval is different for each coin and exchange.
