Embodiment 1

[0069] Such as figure 1 As shown, the present invention provides a blockchain-based transaction method, including:

[0070] Step S1: When conducting a transaction, the payee writes a "receipt statement" on the blockchain; the payer writes the corresponding "payment commitment" on the blockchain;

[0071] Step S2: Conduct credit evaluation based on the transaction amount and the credit status of the payer; the payee writes the corresponding "transaction established" item in the blockchain according to the credit evaluation result to indicate that the transaction is established, or writes the corresponding "transaction approved" item in the blockchain. Rejected” to indicate that the transaction has been rejected;

[0072] Step S3: If the transaction is rejected, the payee and the payer cannot complete the transaction through the blockchain;

[0073] Step S4: If the transaction is established, the funds in the payer's bank account are transferred to the payee's account as agree...

Embodiment 2

[0133] In order to better describe the technical solution of the present invention, the specific process of a preferred embodiment of the present invention will be described in detail below, as figure 2 As shown, this embodiment provides a blockchain-based transaction method, including:

[0134] Step 101: When conducting a transaction, the payee writes a "receipt statement" on the blockchain;

[0135] Step 102: The payer writes the corresponding "payment commitment" on the block chain;

[0136] Step 103: The transaction settlement node conducts credit evaluation according to the transaction amount and the credit status of the payer, and writes the "credit evaluation completed" item on the blockchain after completion;

[0137] According to the credit evaluation result, if the credit evaluation is passed, proceed to step 104: the payee writes the "transaction established" item on the block chain;

[0138] At the same time, write the reason for the establishment of the transac...

Embodiment 3

[0152] Such as image 3 As shown, according to another aspect of the present invention, the present invention also provides a blockchain-based transaction system, including: a blockchain system 1; the blockchain system 1 includes: a payee node 11, a payer Node 12 and payment settlement node 13;

[0153] The payee node 11 is used to write the "collection statement" in the block chain system 1 when conducting a transaction; the payer node 12 is used to write the corresponding statement in the block chain system 1 when performing a transaction. "payment commitment";

[0154] The payment settlement node 13 is used to perform credit evaluation according to the transaction amount and the credit situation of the payer; the payee node 11 is also used to write the "transaction established" item in the block chain system 1 according to the credit evaluation result to indicate The transaction is established, or the corresponding "transaction rejected" item is written to indicate that t...

Abstract

The invention provides a transaction method based on block chain, and the method comprises the steps that a payee writes a collection declaration into the block chain during transaction; the payer writes in a corresponding payment commitment; credit evaluation is carried out according to the transaction amount and the payer credit; the payee writes a transaction establishment item or a transactionrejection item into the block chain according to the credit evaluation result; and if the transaction is established, fund in the payer account is transferred into the payee account according to theagreement, and writing a transaction completion item into the block chain. The invention further provides a corresponding system. Regret cannot be caused when the transaction is established; and the situation that the payer cannot meet the payment condition all the time is avoided through a credit assessment and insurance mechanism, the situation that the payer cannot perform transaction due to insufficient or non-concentrated existing funds and the trouble of two transaction parties caused by payment means are solved, and the two transaction parties are better served.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a block chain-based transaction method and a block chain-based transaction system. Background technique [0002] At present, when the two parties of the transaction are conducting transactions, they often encounter the situation that the payer hopes to conclude the transaction immediately, but due to various reasons, the payment cannot be completed immediately, for example: the payer temporarily does not have enough cash (deposit) or credit ( card) amount, although the cash will arrive soon; or, although there is sufficient cash (deposit) or credit (card) amount, but not in the same bank account, the funds are scattered everywhere, and it is not easy to concentrate together; and some accounts may not have opened online banking, etc., and at this time the payee requires that the payment must be completed, resulting in the failure to complete the transaction; it has formed a c...
