Detailed Description

In order to make the objects, technical solutions and advantages of the present disclosure more apparent, the technical solutions of the present disclosure will be clearly and completely described below with reference to the specific embodiments of the present disclosure and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person skilled in the art without making any inventive step based on the embodiments in the description belong to the protection scope of the present application.

The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.

Referring to fig. 1, the scheme of the present application provides a block chain-based method for tracking government finances, comprising the following steps:

s11, building a block chain platform, and respectively generating a trusted timestamp and a trusted random number according to the receiving and dispatching behaviors.

The blockchain platform in this embodiment may be constructed, for example, by a Fabric framework of a super book, or may be constructed by an ethernet network, and specifically, the technical problem that the blockchain platform should be solved according to what kind of framework is constructed is determined, which is not limited in this embodiment. For ease of understanding, the blockchain platform in this embodiment is constructed from a Fabric framework, unless specifically noted otherwise.

And S12, respectively binding the trusted timestamp and the trusted random number to the income and expenditure behaviors, collecting the income and expenditure information in the income and expenditure process, and generating a financial income and expenditure record.

The balance information in this embodiment includes at least one of the following: sponsor, beneficiary, use, income amount, expenditure amount, income time, expenditure time, etc.

And S13, uploading the financial income and expense records to a block chain platform through an intelligent contract, and encrypting the financial income and expense records to generate an encrypted file.

And S14, decrypting the encrypted file to obtain a decrypted file, and auditing the balance record in the decrypted file.

Preferably, the audit of the balance record may be performed according to a preset time period, where the time period may be, for example, one week, one month, or even one quarter, and this is not limited by the embodiment of the present invention. In addition, the financial income and expenditure auditing mainly comprises the performance auditing of the budget of the level, the performance and settlement auditing of the budget of subordinate government, other financial income and expenditure auditing and the like.

And S15, disclosing the auditing result.

Specifically, the audit result may include, for example, one of a financial deficit, a financial surplus, and a financial balance. When the audit result is disclosed to the public or a superior government, the audit result can be disclosed through a related website of the government, can be announced through media such as broadcast, television, newspaper and the like, and can also be disclosed through a statistical report and the like of a third party organization.

In step S12, the government income and expenditure may be divided into two types:

the financial revenue may include, for example, at least one of: tax revenue, non-tax revenue, social security fund revenue, national property revenue, debt revenue, diversion revenue, and the like. The tax income may include circulation tax, income tax, property tax, resource tax, behavior tax, etc.; non-tax revenue including government funds, lottery equity funds, national paid use income, national asset paid use income, penalty income, donation income on behalf of the government, central income of governing bodies, interest income generated by government financial funds, etc.; the social insurance fund income is divided into basic endowment insurance fund income, unemployment insurance fund income, basic medical insurance fund income, industrial injury insurance fund income and fertility insurance fund income according to projects; the national asset earnings comprise incomes such as profits, rent, dividends, fund use fees and the like obtained by governments by virtue of the acquisition rights of the national assets; debt revenue includes paid revenue that governments take by credit, and the like. The embodiments of the present invention are not limited to the specific forms of the above-described government financial income, and are not exemplified one by one.

Financial expenditures may include, for example, at least one of: general public service expenditure, public safety expenditure, education expenditure, scientific and technical expenditure, social security and employment expenditure, medical health and family planning expenditure, energy-saving and environment-friendly expenditure, urban and rural community expenditure and the like. The education expenses mainly comprise education public expense, education basic construction expense and the like; the social security and employment expenditure mainly comprises social security fund assistance expenditure, administrative and public institution retirement expenditure, employment assistance expenditure, urban resident minimum life guarantee expenditure, rural minimum life guarantee expenditure, natural disaster life rescue expenditure and the like; the embodiments of the invention are not limited with respect to specific forms of government financial expenditure and are not to be construed as exemplary.

The trusted timestamp refers to a complete and verifiable electronic certificate issued by an authoritative trusted timestamp service center, which can prove that a data message (electronic file) is existed at a time point and has legal effectiveness. The trusted timestamp in the embodiment of the present invention may be provided by a third party timestamp service center, or may be provided by the blockchain platform itself, which is not limited in the embodiment of the present invention.

In addition, when generating the trusted random number according to the balance and earning behavior, the embodiments of the present invention provide the following two different implementation manners:

implementation mode one

Referring to fig. 2, the method comprises the following steps:

s21, performing a hash operation on the block header of the block corresponding to the receiving and distributing behavior to obtain a first hash value.

And S22, carrying out hash operation on the first hash value and the time corresponding to the receiving and paying behaviors to obtain a second hash value, and taking the first hash value and the second hash value as trusted random numbers.

Second embodiment

Referring to fig. 3, the method comprises the following steps:

s31, performing a hash operation on the block header of the block corresponding to the receiving and distributing behavior to obtain a first hash value.

And S32, carrying out hash operation on the first hash value and the random parameter to obtain a second hash value, and taking the first hash value and the second hash value as a credible random number.

The random parameter is provided by the initiator of the check-in and payment behavior, and may be, for example, financial staff of the government, leadership, staff of the auditing institution, and the like. And the random parameter comprises at least one of: initiator identity ID, initiator name, initiation amount, beneficiary identity ID, beneficiary amount, and the like.

As a preferred implementation of the embodiment of the present invention, when writing the financial balance records into the intelligent contracts, the principle of "few subject to majority" needs to be observed. By "majority-less," it is specifically meant that all nodes in the blockchain platform need to be broadcast before writing the financial balance records into the intelligent contract, and that the balance records can only be written into the blockchain platform after most nodes have agreed, i.e., the uplink is completed. It should be noted that "few subject to majority" does not refer to the number of nodes, but may be the computing power, the number of shares, or other characteristic quantities that can be compared by the computer.

When the financial records are encrypted, for example, an asymmetric encryption manner may be adopted, or a symmetric encryption manner may be adopted, which is not limited in this embodiment. Preferably, the encryption mode in the embodiment of the present invention may be, for example, encryption by using an asymmetric encryption algorithm. Generally, an asymmetric encryption algorithm requires two keys, namely, a public key (public key) and a private key (private key), where the public key and the private key are paired, and if data is encrypted by the public key, only the corresponding private key can be used for decryption. This kind of encryption mode can promote the secret degree of block chain platform information data, prevents revealing of information, and then prevents artificially maliciously to falsify information data, and this has guaranteed authenticity and reliability of data at to a great extent.

The blockchain technology is applied to the field of government financial tracking, and all nodes added into a blockchain platform can acquire the financial income and expense records uploaded to the blockchain platform, so that the public can know the government financial income and expense conditions more clearly, and further the trust of the government is increased. In addition, the credible timestamp and the credible random number are bound for the income and expenditure behavior, so that the authenticity of the data can be further improved, and the data can be prevented from being arbitrarily tampered by others, so that the public trust of the government is finally improved. When the receipt and payment records are checked, the check can be realized through any node (such as a computer), so that the checking efficiency is higher, and more convenient and quicker office work is realized.
