Embodiment 1

[0045] As mentioned above, the transaction process of the present invention is as follows, as figure 2 Shown:

[0046] If it is the first time user, it will first enter the member management module through the user identity initialization interface to register, and then enter the service layer through the identity authentication interface after successful registration; if it is an old user, it can directly enter the service layer through the identity authentication interface;

[0047] ① The merchant presents the QR code to the user to request payment.

[0048] ②The user scans the QR code to confirm the transaction.

[0049] ③ At this time, the transaction money does not enter the merchant's account, but enters the chain code service module. The merchant confirms the execution of taxes at the terminal, and the chain code service module pays taxes according to the tax rules, and deposits the tax bill into the block service module.

[0050] ④ The merchant executes payment coll...

Embodiment 2

[0055] As mentioned above, the proof process of the present invention is as follows, as image 3 Shown:

[0056] ① After the tax department proves the electronic taxation process of a transaction through the supervision interface, the supervision module generates a tax bill for the transaction, and the block service module hashes the tax bill, and records the private key signature in the block service module.

[0057] ②The tax department encrypts the tax bill with the buyer's public key and sends it directly to the buyer.

[0058] ③ The buyer presents the tax bill to the company for reimbursement.

[0059] ④ The company finds the corresponding certification information of the block service module through the authentication record query interface, and compares the tax bill after verification with the seller's public key with the result of the hashed tax bill to complete the proof of reimbursement.

[0060] To sum up, the present invention realizes the automatic taxation funct...

Abstract

The invention provides blockchain-based tax architecture. The blockchain-based tax architecture comprises a service layer and a data interface layer; the service layer is connected with the data interface layer; the service layer triggers the interior of the service layer to work cooperatively through an event flow, so that a blockchain service is provided; a block service module and a chain codeservice module are also arranged in the service layer; the block service module is used for storing signed data subjected to hash processing; and a tax rule is stored in the chain code service module.According to the blockchain-based tax method and architecture provided by the invention, trusted information is shared; a database is managed and maintained by multiple parties together through decentralized architecture; any one party cannot completely operate data; a blockchain cannot be tampered by depending on the hash pointer of each block head and the Merkle tree of a block; the data security is reinforced through a consensus mechanism; and thus, justice and equity are promoted.

Description

technical field [0001] The invention relates to a blockchain-based taxation method and framework, belonging to the technical field of blockchain applications. Background technique [0002] In the existing technology, taxation lacks a comprehensive top-level design, and the respective taxation systems are difficult to expand. Regular automatic data reporting leads to large data delays and low system efficiency. In this way, small-amount transactions are too trivial, and it is inconvenient for the tax bureau to track down large amounts. Even if the transaction is traced, it will consume a lot of manpower and material resources. Therefore, there is a public account book in the blockchain system to record the user's operation behavior. In the case of Alipay, WeChat and other electronic payment methods are becoming more and more common, the blockchain system is introduced into electronic payment, using smart contracts. Realize zero tolerance for tax evasion. [0003] The existi...
