Description

Fast blockchain trading method

The present invention relates to a blockchain transaction method, and more particularly to a blockchain transaction method capable of quickly executing a transaction.

In the existing blockchain trading method, the blockchain system generates a hash value based on all transactions included in a block, that is, a Merkle tree root; Each block can be connected in series through a block of block headers containing a hash value for each block.

In order to increase the security of the hash value, it is often necessary to utilize multiple transactions to generate the hash value. Therefore, in general, after a new transaction is generated, it will be added to a block by the blockchain system. After the block contains multiple transactions, the blockchain system will add the block to the current block. The blockchain completes each transaction in the block. Therefore, as far as the existing blockchain trading method is concerned, after a new transaction is generated, it will not be executed immediately, and the immediacy of the execution of the transaction is insufficient.

Therefore, the object of the present invention is to provide an instant transaction that can be achieved. Fast blockchain trading method.

Thus, the fast blockchain transaction method of the present invention is used to conduct a transaction and is implemented by at least a first computer system. The transaction corresponds to a target transaction data. The fast blockchain transaction method includes a step (a), a step (b), and a step (c).

The step (a) is that the first computer system generates at least one virtual transaction data.

The step (b) is that the first computer system generates a block containing the target transaction data and the at least one virtual transaction data.

The step (c) is that the first computer system adds the block to a blockchain.

The effect of the present invention is that by instantaneously generating the at least one virtual transaction data and the block including the target transaction data and the at least one virtual transaction data, the block can be immediately added to the blockchain, and the instant is achieved. transaction.

Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.

An embodiment of the fast blockchain transaction method of the present invention is used to conduct a transaction and is implemented by a first computer system. The transaction corresponds to a target transaction data, and the target transaction data includes at least one digital signature associated with the transaction. The first computer system corresponds to a public key pair including a private key and a public key.

Referring to FIG. 1 and FIG. 2, in the process of conducting a transaction, first, the first computer system verifies the authenticity of the at least one digital signature of the target transaction data (step 11).

Then, if the result of the verification is true, the first computer system generates a plurality of messages, and generates a plurality of virtual transaction materials by individually digitally signing each message by using a corresponding private key thereof, wherein Each virtual transaction data includes one of the at least one digit signatures (step 12).

Each message contains an identical timestamp for recording the time at which the message was generated. Except for the timestamp, the content of such messages is not limited and may be the same or different content. In addition, the amount of virtual transaction data can be determined according to the demand for security. If the number of virtual transaction materials is increased, security is also Relatively improved.

As shown in FIG. 2, after generating the virtual transaction data, the first computer system instantly generates a block 2 containing the target transaction data and the virtual transaction data (step 13).

After generating the block, the first computer system immediately adds the block 2 to a blockchain (step 14).

For example, the transaction is related to the signing of an electronic contract corresponding to a first contractor and a second contractor, and each contractor corresponds to a public key pair containing a private key and a public key. The target transaction data includes a first contract signature and a second contract signature, wherein the first contract signature is generated by the first contractor by digitally signing the contract by using the private key corresponding to the contract. And the second contract signature is generated by the second contractor by digitally signing the contract by using the private key corresponding to the contract.

In an embodiment, the first contractor and the second contractor respectively generate the first contract signature and the second contract signature through an electronic contract platform, and then the first computer system re-enters the electronic contract The platform receives the first contract signature and the second contract signature, and generates the target transaction data accordingly. In another embodiment, the first contractor and the second contractor can directly establish the first contract signature and the second contract signature on the first computer system, and then the first computer system The target transaction data is generated accordingly.

After receiving or generating the target transaction data, the first computer system respectively uses the public key corresponding to the first contractor and the public key corresponding to the second contractor to sign the first contract and the second The contract signature is verified. The first computer system generates a plurality of virtual transaction data when the first computer system verifies that the first contract signature is true and the second contract signature is true.

Then, the first computer system generates a block containing the target transaction data and the virtual transaction materials, and immediately adds the block to a blockchain to complete the signing of the electronic contract.

Referring to Figure 3, initially, the blockchain 4 is empty, and after joining the block, the block is the first block 41 of the blockchain 4. Then, when the first computer system 3 generates the second block 42 including another target transaction data according to the foregoing steps 11 to 13, the first computer system 3 is included according to the first block 41. The target transaction data and the virtual transaction data calculate a corresponding Merkel root; then, the first computer system 3 causes the header of the second block 42 to include the Merkel root, thereby taking the second Block 42 links to the first block 41; thereafter, the next block joins the blockchain 4 by linking with the second block 42, and so on.

In addition, in another embodiment, after receiving or generating the target transaction data, the first computer system may digitally sign the target transaction data and the set of the virtual transaction materials by using the private key corresponding to the first computer system. And generating a transaction signature and generating a block containing the transaction signature; thus doing the target transaction data For further security protection, the user needs to use the public key corresponding to the first computer system to verify the transaction signature before obtaining the target transaction data.

In addition, in another embodiment, as shown in FIG. 4, the first computer system 3 can also transmit the generated block to a second computer system 5, so that the second computer system 5 stores the same. The first computer system 3 has the same blockchain 4. That is to say, in addition to forming a blockchain system only by the first computer system 3, the first computer system 3 and the second computer system 5 may together form a blockchain system.

In summary, the fast blockchain transaction method of the present invention generates a plurality of virtual transaction materials in real time after receiving or generating a target transaction data by the first computer system, and includes the target transaction data and the The block of virtual transaction data can instantly add the block to the blockchain and meet the security requirement, that is, to complete the transaction related to the target transaction data and meet the security requirement in real time, without waiting for the Since the block contains a plurality of real transaction materials before the transaction is made, the object of the present invention can be achieved.

However, the above is only the embodiment of the present invention, and the scope of the invention is not limited thereto, and all the simple equivalent changes and modifications according to the scope of the patent application and the patent specification of the present invention are still Within the scope of the invention patent.
