According to the present invention, a dealing method of crypto-currency based on a block chain system comprises the steps of: creating a private key of a member by using a function using a crypto-currency exchange program when a combination of numbers and letters in or over predetermine digits or numbers is inputted; creating and storing an exchange web wallet address of the member in an exchange web wallet paired with the private key as soon as the private key has been created; creating the exchange web wallet address of the member in an exchange server without storing the private key in order to tighten security; creating an address of an exchange general wallet installed in the exchange server having a database storing the crypto-currency transactions of the member; creating an exchange address of the stored member in the exchange server to allow the member to make a crypto-currency deal; transmitting crypto-currency to the address of a general wallet of the exchange (or a third party) from the exchange web wallet address of the member by the member in order to allow the rapid closing of a crypto-currency deal; and a step of depositing a value of the crypto-currency in the database as an account of the exchange server instead of the actual crypto-currency to the exchange address of the member after confirming the transfer of the crypto-currency to the address of the general wallet of the exchange (or the third party) from the address of the exchange web wallet of the member in the exchange server by the member.

Description

[0001] The present invention relates to an encryption method using a block chain structure,

The present invention creates a member's private key using a function when a combination of digits and characters larger than digits set in the exchange program represented by the bit coin is input, (DB) in which the private key is not stored in any place and the member's bit coin transaction details are stored in order to increase the security, , The member generates the address of the member stored in the exchange server for trading the bit coin, and in order to promptly process the bit coin transaction, the member transmits the address of the exchange (or the third party ) To send the bit coin to the general purse address, After confirming the transmission of the bit coin from the address of the small web wallet to the general purse address of the name of the exchange (or a third party), deposit the bit coin to the member's exchange address as a numerical value on the database, The present invention relates to a method of trading a bit coin including a step of giving a payout amount.

All of the crypto-currencies running in the block-chain system, including bit coins, are made up of a pair of keys in the form of a 'private key-public key (address)' at the user end. The public key corresponds to the bank account number and the private key corresponds to the password, which is a pair that fits only with one another.

In the case of the bit coin QT program (user's personal wallet program), the private key is encrypted using the user's password and stored in the member computer.

 In the case of Web Coin Exchange, a private key is encrypted and stored on the server using user password or SALT of the server.

Anyway, the existing approach is to store the private key on the server or store it on the member computer.

In other words, the Exchange security related internal person who knows how to encrypt is likely to decrypt the encrypted private key stored in the server and secretly use it.

When a member views his or her account through an exchange server, the balance stored in the server database (DB) is displayed. The actual balance existing at the address is meaningless to the member. The actual transmission of bit coin requires six checks, which takes about an hour, which makes it impossible to trade in a short period of time.

Patent Publication No. 2002-0046561) discloses a technique of purchasing electronic money based on gold by using the Internet and possessing it on cyberspace and using the electronic money based on the gold owned by the electronic money for commercial transactions The difference between the basic principle of money generation and the transaction mode differs from the bit coin in the present invention.

The problem to be solved by the present invention is to add a web wallet of an exchange to a bit coin exchange server in addition to an ordinary purse of an exchange and to add a web coin to an exchange web wallet address from an exchange common wallet address built in an exchange server, In order to improve security.

A problem to be solved by the present invention is to configure a private key of a member's web wallet address not to be stored in any form of a server and / or a member's computer, A method of trading a bit coin that is blocked from the original way.

The problem to be solved by the present invention is that transactions are processed only by manipulating the balance of an exchange database (DB) without transferring actual coins within the exchange address, and the exchange web wallet exists separately from the database (DB) of the exchange server, (DB) of a bit coin that can not be interworked with a database (DB).

Another problem to be solved by the present invention is that a member transmits a bit coin to the general purse address in the name of the exchange (or a third party) at the address of his or her exchange web wallet in order to quickly process the bit coin transaction, After the member confirms that the transfer of the bit coin from the web address of the exchange web site to the general purse address of the exchange (or the third party) is started, the member's exchange address is a numeric value on the database And to provide a quick bit coin transaction method by depositing a bit coin through a change.

Another problem to be solved by the present invention is to provide a bit coin transaction method in which both an exchange web wallet made by an exchange and an ordinary purse of an exchange owned by an exchange and a balance database (DB) of members are controlled by an exchange server.

According to an aspect of the present invention, there is provided a method for generating a private key of a member using a function when a combination of a number and a number of digits or a predetermined number of digits is input; And generating and storing an exchange web wallet address of a member stored in the web site wallet of the exchange at the same time of generating the private key, and implementing a bit coin transaction method in which the private key is not stored anywhere to enhance security have.

A further object of the present invention is to implement a bit coin transaction method for generating a private key by combining hash information and user information with a cryptographic technique for encrypting a user password.

Another object of the present invention is to provide a method and apparatus for a member to access a web address of a web site for a bit coin transaction, Key, and generates a bit coin transaction method in which authentication is completed when the generated private key is compared with a member web site address of a web site and the pair is matched.

According to another aspect of the present invention, there is provided an electronic commerce system, comprising: Generating an address of an exchange general purse built in an exchange server having a database (DB) in which a member's bit coin transaction details are stored; And generating a member exchange address of a member stored in an exchange server for trading a bit coin, wherein, in order to expeditiously process the bit coin transaction, the member registers the exchange (or a third party) And transmits the bit coin to the address of the general purse of the member. After confirming that the member starts the transmission of the bit coin from the address of the exchange web wallet to the address of the general purse of the exchange (or the third party) And depositing a bit coin by changing a numeric value on a database which is a book of an exchange server rather than an actual bit coin.

Another solution to the problem of the present invention is to provide a bit coin transaction method configured to control an exchange web wallet created by an exchange, a general purse of an exchange held by an exchange, and a balance database (DB) of members in an exchange server.

The present invention further improves security by using a bit coin stored in an exchange web wallet address from an exchange common wallet address built in an exchange server in addition to a web wallet of an exchange in addition to a general purse of an exchange on a bit coin exchange server There is an advantageous effect.

In addition, according to the present invention, a private key is not stored in an exchange server and / or a member computer, so that the exchange can basically block the way of knowing the private key linked with the web site address of the corresponding member's web site, There is an advantageous effect of increasing the reliability of the apparatus.

According to another advantage of the present invention, transactions are processed only by the balance operation of the exchange database (DB) without transferring the actual coins in the exchange address, and the exchange web wallet exists separately from the database of the exchange server, (DB), so that security and reliability of members can be enhanced.

Another effect of the present invention is that a member transmits a bit coin to the general purse address of the name of the exchange (or a third party) at the address of his or her exchange web wallet in order to quickly process the bit coin transaction, (Or third party) in the exchange web address of the web site, after confirming that the bit coin has been transmitted to the address of the exchange (or third party) And coins are deposited to process a quick bit coin transaction.

Another effect of the present invention is to provide a high security and reliability while controlling transactions on an exchange server by controlling both the exchange web wallet, the general purse of the exchange and the balance database (DB) of the members.

Hereinafter, the present invention will be described in detail.

The present invention relates to a method and apparatus for generating a private key of a member using a function when a combination of digits and characters greater than a predetermined number of digits in a bit coin exchange program is input, The wallet address is generated and stored, and the private key is configured not to be stored anywhere in order to increase security.

In order to improve security, the present invention generates an address of a member's web site purse of an exchange on an exchange server, generates an address of an ordinary purse of an exchange built in an exchange server having a database (DB) , A member creates an exchange address of a member stored in an exchange server for trading a bit coin, and in order to expedite the bit coin transaction, a member inserts an ordinary purse (or a third party) (Or a third party) at the exchange server after confirming that the member has initiated the transmission of the bit coin from the web address of the web site of the exchange to the general purse address of the name of the exchange (or a third party) Is a member's exchange address, and not the actual bit coin, deposits the bit coin into the numerical value on the database which is the account of the exchange server And a step.

The meaning of the bit coin and the payment method are examined.

Bitcoin (BTC, Bitcoin) system was developed in 2009 by an individual or group of programmers who use the nickname Nakamoto Satoshi. It is basically a P2P (pear-to-pear) It is based on a distributed database. In short, it means that individual computers or servers with bit coin programs installed collectively create a whole bit coin system.

In this system, what we call bit coin is created through the act of Mining (which is originally called Data Mining, which means "information mining" in our country, but "mining" in Korea) You can store and trade in your wallet. These bit coins are currently being mined and circulated by about 13.8 million, and 21 million are scheduled to be mined sequentially in 21 million.

The following is a look at Mining.

The most important word in the description of bit coin is Mining.

Mining is usually a way to get a new bit coin. The process of providing a bit coin to a computer that finds it first by competing with a computer (terminal) constituting a bit coin network to find an operation value satisfying a specific condition is called mining. However, this mining is not only a method of acquiring a simple bit coin but also a role of authenticating a bit coin transaction.

Suppose that a general financial transaction occurs between A and B. The two of them will obviously have financial transactions with money, and it is not necessary to argue that someone else has had such a deal because it has the power to be recognized by the government and the law.

If money or goods are exchanged between each other, it is enough. Rather, the desire to be a secret is stronger. Most people do not want to let themselves know that they have money and have traded something with it.

But the story of Bitcoin is a little different. Since the bit coin has a starting point that is not related to the government, the law, or the central bank, the bit coin determines whether the transaction between A and B is a normal transaction or a fake transaction by hacking or the like, Is an important issue.

The bit coin solves that by noting everyone around it that there was a trade between A and B. By encrypting and transmitting the transaction contents to all terminals (computers or servers) connected horizontally to each other on the network, all of them allow the transaction to be acknowledged.

It also orders the terminals to encrypt their transactions and make them into one block (block chain). The number of terminals participating in this cryptographic operation is also very easy to understand because of the mining.

The following is a description of the features of bit coin.

 The beat coin has a distinctive feature that distinguishes it from various existing currencies or trading systems.

 First, there is no specific bit coin issuer as described above.

 No country, no government, no central bank, no institution, no company, is involved in the issuance of bit coins, but bit coins are produced only through individual nodes (computers and / or servers) participating in the network. In other words, foreign countries, institutions, and organizations are essentially shielded from their intervention by their own circumstances and needs.

Second, the issue amount of bit coins is limited.

The bit coin is programmed so that 21 million are issued by 2140 as described above. Currently, more than 13.8 million have been issued, and these issuances are scheduled in advance and can not be adjusted from outside. It is not necessary to worry about the depreciation of the monetary value due to inflation, which was explained in the history of monetary history, following the continuous issue of money.

Third, anonymity is guaranteed.

The bit coin address has anonymity because it does not contain information about the owner. Bitcoin users can have multiple addresses and can create new addresses without limit. Simply creating a new public key and cryptographic key pair without having to contact any network node can instantly create a new address.

Fourth, transaction costs associated with transaction through bit coin are small enough to be negligible.

The average transaction fee of 0.0002 BTC per transaction is about 50 won when converted to current market price. This is because the transaction cost that accompanies cash transaction is smaller than any transaction other than direct cash transaction, It opens.

The following explains the value of the Crypto-Currency system.

What we should look at is not the 'bit coin' as a cipher but the 'cipher system' represented by a bit coin. It is important that this system can make a difference in the world we live in.

As we have seen, intuitively, the world we live in turns to money. However, it takes money for this money to roll. Let's say we pay 100,000 won. If you pay 100,000 won for a credit card at the mart, the credit card company will take 1,500 won, which is about 1.5%, for the fee. If you pay 100,000 won for a hair salon, this fee will increase to around 3,000 won. If you use 100,000 won for small phone settlement, the fee will increase to about 8,000 won. If you sell 100,000 won at Chopin Mall in G-Market or 11th Avenue, you should pay a commission of 10% to the company besides 3% credit card fee. If you pay 100,000 won on Google or Apple's App Store for a smartphone, the commission goes up to 30%.

But the Bitcoin system is a shock to these existing fee systems.

The bit coin naturally has functions of money and payment at the same time.

Bitcoin makes all other external payment systems unnecessary for the transaction.

The bit coin is the same as carrying the check card and its payment terminal at the same time (assuming that it is the Internet). Automatic exchange is a bonus. The fee is much smaller than any other system ever has.

Of course, the check against him is already taking place. Apple has recently declined to register all of its Bitcoin-related apps in their App Store since late 2013, In addition, due to the possibility of being used for tax evasion or crime, I do not want to recognize the bit coin in the system right now.

But let's assume that you are a self-employed person who sells to a lot of ordinary people. Regardless of the type of industry, after paying for raw materials, labor costs, and rent payments, you usually earn between 10 and 30 percent of your sales. At the margin of 10 ~ 30%, 3% of the card fee will account for about 10 ~ 33%. You can take advantage of 10 to 30 percent of your margin by simply changing your payment method or including a bit coin as a payment method.

If you make money in the United States, etc., and transfer money to a banking system like Africa, you will pay a commission of 10 ~ 15%. This can be done quickly and inexpensively by using bit coin. There are also techniques to transmit and authenticate bit coins only by using mobile phone text messages in case the internet environment is poor.

In addition to this, there are many fields that can apply block chain technology, which is the core of encrypted money, such as proof of authenticity of various documents and data through p2p, encryption of stock-bond-registration part, and individual issuance and transaction system.

As of February 10, 2015, more than 1,300 kinds of encryption currencies have been issued worldwide, but bit coins account for more than 80%. Bitcoin's market capitalization amounts to approximately KRW 3.5 trillion (13.8 million * 230 $). Throughout the world, the amount of transactions through the Bitcoin Exchange is an average of $ 40 million per day, and the daily average payment amount Is about $ 1 million.

Worldwide companies that receive payments by bit coin now include DELL (computer), MicroSoft (software), Expedia (the world's largest online travel agency), and Braintree, a subsidiary of PayPal (billing) It is. The approximate franchise status can be found at http://coinmap.org .

The following is the structure of the Crypto-Currency.

Crypto-currencies represented by bit coins have a common type of transaction book called a block chain.

The outline is as follows.

General users download encrypted wallet program. Then install it on your own computer. Then, the program starts executing the task of synchronizing itself with the block chain recorded on the network while it is being executed. Because the data is tens of gigabytes, it usually takes 3-7 days. After the synchronization is completed, you can create your own address (the concept of an account at the bank) in your wallet and send or receive a bit coin through that address. (In the case of bit coin, (Upper / lower case) and numbers.

ex) 1MowqQrQJL5AeaDMpX35B6EiJ4qnXPJnFp)

There are special users that are not ordinary users. They download a mining program that is not a regular wallet program. Each of these users is referred to as a node, and these nodes are connected to each other to provide computing power (sum of CPU or graphics card's computing power) to transmit the transmission records of the encrypted money between the general wallets to the block chain It records and encrypts everything. In return, the encrypted money system generates and distributes new coins probabilistically in proportion to the computing power (Hash, hash) provided to each of these nodes, and collects and distributes the commissions required for transmission.

These new coins (currently 20 in the case of bit coin) and transmission charges are motivated by the nodes to participate in the encryption process of such a block chain. These actions are called 'mining' .

It is this that gives a bit coin when solving complex mathematical problems known to the general press.

In the case of bit coin, a new block is created every 10 minutes, which is a collection of all the transmission records from the entire network for 10 minutes. It is the block chain in which each block is cumulatively recorded. In conclusion, the block chain can be understood as a "transaction book" that is a collection of transaction records from the beginning of the virtual currency to the present.

When a wallet user requests the coin to be transmitted to the network, the neighboring nodes sequentially transmit the corresponding transmission request And records it in the block chain that this is the correct transfer request. This record must be made six times to ensure that the transfer is complete and that the system will be fully authorized and the ownership of the coin will be fully transferred. One such record is called a confirm, and 6 conform must be made on the network before the ownership of the coin is completely surpassed.

In the case of the bit coin, one new block is generated in about 10 minutes. Therefore, it takes about 1 hour to perform the 6 conform in the coin transfer request.

The following explains the use of Crypto-Currency.

Bitcoin users can store their bit coins on their personal PCs and leave them to the general purse and web wallet of the exchange.

The reason why you want to keep your bit coin yourself is because you are afraid that if you leave it to the exchange, the exchange will take your bit coin.

It has already been done on several large exchanges. At the time, Mt.Gox, the largest bank in the world, was in the process of bankruptcy because its coins of about 320 billion won were withdrawn unfairly. In this case, you may not be able to find the coin forever when your computer is broken, and in fact, personal computers often fail. Or, a password may be leaked through a malicious program installed on a personal computer, and the contents of the virtual money wallet may be hijacked. In addition, there is a disadvantage in that it is difficult to quickly respond to changes in the market price because it takes time to transfer to the KRX when the price of the bit coin changes rapidly.

The reason for leaving it to the exchange is the opposite. The Exchange periodically backs up the wallet systematically and has a superior defense system against personal computer (PC) against hacker 's intrusion. You can also respond immediately to sudden changes in the market price. However, there is also a great concern that the exchange itself will have a coin with the coins left by members.

The reason why this is happening is due to the peculiarity of the purse of the virtual currency.

For virtual money users, there is a higher concept called 'wallet' and a sub concept called 'address'. Within a single wallet, a user can create a myriad of addresses at random, and these addresses are managed as one password for that wallet.

Transmitting coins to their own address on the Exchange is because it sends bit coins to one of the addresses managed by the Exchange, so the Exchange can of course manage all the members' bit coins as one of the Exchange's wallet passwords. do.

Apart from the wallet responsible for the transfer of the bit coin, the exchange operates a program for managing the database (DB) in which the balance of the members' bit coins is recorded. It takes about an hour to actually transfer the bit coin. Therefore, rather than taking the method of transmitting the actual bit coin between addresses when a transaction of bit coin occurs between members, And the like.

The balance and transmission history of all member addresses are all inquired in the block chain. For this reason, the balance existing in the DB of the members of the general exchange and the actual balance existing at the corresponding address must be different.

In addition to the above mentioned 'User Personal Wallet' and 'Exchange General Purse (broadly, Exchange Private Wallet)', there is also a 'Web Wallet'. This allows you to create a personal wallet on your web (network), not your personal computer, to store coins.

When using 'coin' instead of 'transaction' in online and offline, there are restrictions due to '6 conform' system.

It takes about an hour to go online, but it does not matter if the coin is transferred anyway. But if you ask for a bit coin 'transfer' after offline purchase, it will not be inconvenient for you to transfer the coin's ownership in about an hour . There are some places where only 3 consul agreements are made, but there is a danger that the coin transfer which is not 6 conformed basically can become a 'non-existent' transaction.

Hacking, etc., and false information spreads on the network, it means that there is a possibility that the transmission request of 6 conform or less is invalidated. A specific embodiment according to the present invention will be described.

<Examples>

A specific embodiment according to the present invention will be described.

The present invention does not store the private key anywhere, including a computer, a server, etc., so that it is not known or hacked by anyone.

The first important technical feature of the present invention is that no 'private key' is stored anywhere.

In the encrypted currency system, the private key-public key (the address of the open encrypted currency) is paired and acts as security maintaining means. To use the encrypted currency in someone's public address (public key), you only need to know the private key. However, this private key itself is not a password that the user uses to memorize.

Typically, this private key is encrypted with the user's password. At the time of use, the encryption key is decrypted by inputting the encrypted private key from the server or the member, and the private key is extracted, and then the encrypted key contained in the public key (address) is handled by the extracted private key.

Private key storage methods of security companies such as existing financial institutions and game companies all randomly generate private keys and then encrypt them using a user's password or its own salt and store it in a server. When a member requests to notify them that they have forgotten their password, they must have the information in some form to respond.

Salt means literally salt, so it's hard to find someone else's encryption structure by hitting a salt that is known only here in the middle of encryption.

In the case of the bit coin QT program (user's personal wallet program), the private key is encrypted using the user's password and stored in the member's personal PC.

In the case of a bitcoin web wallet, the private key is encrypted and stored on the server using a user password or a salt of the server.

In any case, the existing method is to store the private key in the server or store it in the member. In other words, the Exchange security related internal person who knows how to encrypt is likely to decrypt the encrypted private key stored in the server and secretly use it.

In order to solve the above-mentioned problems, the present invention includes a technical configuration in which a bit-coin exchange server operated by an operator additionally constructs an exchange web wallet in addition to an ordinary exchange purse.

The purpose of the present invention is to allow a member to transfer a coin from an exchange common wallet address embedded in an exchange server to an exchange web wallet address.

Exchange General Purse Address and Exchange Web Wallet Address can be stored and managed on the same server or on different servers.

The web address of this exchange web site is configured so that individual members can manage the private key (password) of the corresponding address. Therefore, it is impossible for a member to directly deal with managing a bit coin at an exchange web wallet address.

As described above, in the address of the general purse of the exchange, the transaction is processed by only the DB balance operation without transmitting the actual coin. However, since the exchange web wallet exists separately from the DB of the exchange server and can not be linked with DB of the exchange server Because.

This is a structure in which the exchange can not use members' coins privately.

It is a technological composition (invention) invented in order to further enhance trust in the exchange by blocking the way for the KSE to know the private key (password) associated with the member's web site address.

A fatal disadvantage of the system according to the present invention is that if a member does not remember the private key (password) set by the member, the access to the Exchange web wallet address of the corresponding Exchange server may be blocked, .

For other existing servers

a. For private key generation

Enter user password - randomly generate private key on server - Encrypt private key with user password. In this case, the encrypted private key is stored in the server.

b. For private key use

 Enter user password - decrypt the encrypted private key stored in the server - can execute the corresponding command.

The technical construction according to the present invention will be described.

a. For private key generation

Enter user password - After merging some information (membership number, order, e-mail, etc.) in the exchange program installed on the member's PC and not the server, generate the private key with the hash function. The private key is not stored anywhere, including the server.

b. For private key use

User password input - If the private key is generated from the member's PC and the pair is matched with the address stored in the Exchange server, the corresponding command is executed.

In the present invention, since there is no encrypted private key stored in the server or the member computer, it is impossible to decrypt even an internal party.

Bit coin exchange program It is configured to generate a member's private key by using a function when a combination of digits and characters exceeding a predetermined number of digits is input.

The above function is an ambiguous function named by the applicant of the present invention.

The haspone function hashes the user's password to sha256 (cryptography) and then combines this information with some user information (e-mail address, membership number, etc.) to generate a private key. If the user's password is the same, Is generated.

More specifically, the private key according to the present invention is generated by using a hash function in case of inputting a combination of this information and user information (e-mail address, membership number) after hashing the user's password into sha256 At the same time as the generation of the private key, the exchange web wallet address of the member stored in the matching web wallet is created and stored. The generated private key is not stored anywhere.

That is, the private key of the member according to the present invention and the web site purse address of the exchange are generated as a pair, and the generated private key is not stored anywhere.

There may be several URLs for members' Exchange web wallet addresses. In order to generate the member private key, since the information corresponding to the 'order' is different when the user password is shashed to sha256 (cryptosystem) and then this information is combined with the user information (e-mail address, sequence, membership number) This is because the members' Exchange web wallet addresses are created and stored differently.

In order for a member to access the web wallet address for a bitcoin transaction, if the user enters the user password that the member used to create the web address of the exchange web site into the exchange program, the hash function of the sha256 (cryptography) And then generates a private key of a number and / or character combining the user information (e-mail address, order, membership number, etc.), and compares the generated private key with the member's web site address. Is completed.

The user's private key is not stored anywhere on the server and the member's computer. When entering a password for bit coin transfer, a private key is generated as a deterministic function and coin transfer is initiated. It is a way of disappearing from.

The server of the company is separated in the generation and management of the private key (password) of the member so that the company can not obtain the individual's private key (password).

The Exchange web wallet address is not associated with the Exchange database (DB), and therefore bit coin transaction can not be made. That is, for the transaction, the corresponding bit coin must be moved to the address of the general purse of the exchange linked to the exchange database (DB).

The technical construction of Express transmission according to the present invention will be described.

Basically, a lot of addresses can be created in one wallet, and these addresses are all managed as one password in the wallet.

First, I will explain the wallet system of the first exchange.

One member A is said to store the personal wallet address 1 on the external server. The Exchange server has its own address, a. A member may have multiple addresses.

In addition, there are a lot of other members' addresses in the wallet of exchange server, such as b, c, d, ....

If A sends a bit coin from 1 to a, the coin will of course enter the address a. However, the balance of the bit coin in the a address is different from the sum of the bit coins transmitted or subtracted by A itself.

For example, suppose A sends the first 1-bit coin to address a of his Exchange server.

In this case a 1-bit coin comes in via a 6-conform (address balance = 1).

It is also treated that a 1-bit coin is deposited to A's database (DataBase) (DB balance = 1).

In this case, the address balance = DB balance = 1.

There are a lot of transactions in the exchange, but it does not move the actual bit coin in transactions inside, rather than requests to send to the outside. Only the members' DB balance will be adjusted in numbers.

Think about when this member sold this 1-bit coin to someone else in the exchange.

Even after the transaction, there is a 1-bit coin in member's address a. (Address balance = 1)

In the DB balance of the exchange, this member sold 1-bit coin, so 1-1 = 0 (DB balance = 0)

Because this process is repeated, the member's address balance and the DB balance do not match.

When a member views his or her account on the Exchange server, the DB balance is displayed. Address balances are meaningless to members. When a transaction between members is repeated and a request for transfer of the coin from the member comes in, the exchange places a coin of the corresponding quantity at any address in the wallet managed by the exchange such as a, b, c, d ... It will respond to the transfer request. The reason for this is that the actual transfer of bit coins takes about an hour, so the actual coin transfer method in each transaction is often impossible to trade in a short period of time.

The key to the technical construction of the present invention is that 'actual transmission' takes about one hour, but 'transmission in the exchange database' is immediate. This is because it is the act of changing only the number of balances in the books of the members managed by the exchange.

A. Let's look at the existing method.

Member's web wallet address ------------- ① ----------> Member's exchange address

The existing method is simply a method of transmitting a bit coin from the web wallet address of the member (important 1) made by the exchange to the member's exchange address. Since the actual bit coin transmission occurs because it corresponds to (1), it takes about one (1) hour for the 6-conform for the bit coin transmission system.

Express transmission according to the present invention will now be described.

Member's web wallet address --- ① ----> The address of the general purse of the exchange name (or the name of the third party) --- ② ---> It is to go to the member's exchange address.

Instead of sending a member directly from his / her web wallet address to the member's own exchange address, the member transmits a bit coin from his / her web wallet address to the address of the general purse of the exchange name (or a third party name) , The exchange (or the name of a third party) deposits the coin as the number on the DB, not the actual bit coin, as the 'member's exchange address'.

In this case, the actual ① process takes 6 hours and takes about 1 hour. However, the exchange (or the name of a third party) is not required to wait for the 6 conforms and is configured to immediately deposit the corresponding bit coin into the DB balance of the member will be.

This is possible because both the 'web wallet created by the exchange' and the 'general purse of the exchange' and the balance of the members' DB are under control of the exchange.

If a member requests a transfer from the web wallet address of the member created by the exchange to the address of the general purse of the exchange owned by the exchange, the transaction is performed in the web page of the exchange, HTS, or App, You can immediately know that the act is true.

This means that there is no need to wait for "certification of other people", which means the 6 conform which is the core of the technical composition of the present invention.

Therefore, the act of ② can act to directly increase the balance of the members. After 6 hours of consultation, the bit coin due to the act of ① comes naturally into the general address of the exchange (or third party) name.

In other words, the exchange is like lending a bit coin to a member for the time it takes for six consults to be sent.

In summary, the transmission of the bit coin does not occur directly, but a subject (exchange or a third party) capable of providing credit in the middle is interrupted and indirectly transferred from the database (DB) first.

The technical structure of the present invention will be summarized on the basis of the above-mentioned description.

In the bit coin transaction method,

The program provided to the bit coin exchange server includes the steps of generating a member's private key using a function when a combination of numbers and letters greater than a predetermined number of digits is input, And storing and storing the exchange's web wallet address of the member stored in the storage unit of the web site, but the private key is not stored anywhere to enhance the security.

The function generates a private key by combining user information with information obtained by hashing a user's password using a cryptographic technique.

In order to access the server's web wallet address for a bitcoin transaction, the member enters the password used to create the web address of the member's Exchange web wallet into the exchange program, and stores some other personal information (membership number, order, e-mail, etc.) After the combination, the private key is generated through the hash function and the authentication is completed when the generated private key is paired with the member's web site address.

In another bit coin transaction method,

Generating an address of an exchange's general purse built in an exchange server having a DB storing a member's bit coin transaction history; Generating a member exchange address of a member stored in an exchange server for trading a bit coin,

In order to expedite the processing of the encrypted currency transaction, the member transmits the encrypted currency from the address of his or her exchange web wallet to the ordinary wallet address of the exchange or a third party name,

In the Exchange server, after the member confirms the transmission of the encrypted currency from the address of the exchange web wallet to the address of the ordinary purse of the exchange or a third party name, the member's exchange address changes the numeric value on the database which is the book of the exchange server And depositing and processing the encrypted currency.

Both the Exchange web wallet created by the Exchange and the Exchange General Purse held by the Exchange and the Members' balance database (DB) are configured to be controlled by the Exchange server.

In the present invention, a bit coin exchange program generates a member's private key by using a function when a combination of numbers and characters having a predetermined number of digits or more is input, A purse address is generated and stored.
