In this application, the investment project management method mainly relates to an investor, a project party and a third party service provider, and it is understood that the third party service provider may be any one or more of a management team, a consultant and a regulatory agency, which are determined according to actual needs, and are not specifically limited herein.

In order to illustrate the technical scheme of the invention, the following description is given by specific examples:

example 1

Referring to fig. 1, which is a schematic flow chart of an investment project management method according to a first embodiment of the present invention, for convenience of explanation, only a portion related to the embodiment of the present invention is shown, the method includes:

step S10, acquiring investment projects registered and submitted by project parties, auditing the investment projects, and then issuing the investment projects to a blockchain;

wherein in one embodiment of the invention, the investment project management method is applied to an investment project management platform to achieve investment project management. When an investment project is formulated by the project party, the investment party needs to invest to realize the smooth implementation of the investment project, the project party can issue the relevant information of the investment project to the investment project management platform, and the authority and rules of the investment party and the project party are defined. Specifically, if the project party does not register in the investment project management platform, the project party needs to register and fill corresponding registration information and perform identity authentication operation, and can issue the investment project in the investment project management platform after the identity authentication is passed; if the project party registers on the investment project management platform, the project party can directly register on the investment project management platform and submit and release the investment project on the investment project management platform after the identity authentication is passed. It should be noted that, if the item party is an individual, the identity authentication operation is usually face identity authentication; if the project party is a legal organization, the identity authentication operation is generally that the license authentication is performed first, and then the face identity authentication of the responsible person is performed. At the moment, identity authentication technology is adopted for the project party so as to ensure the identity information of the project party and the authenticity and safety of investment projects, and the problem of investment loss possibly caused by false investment projects released by the project party with unknown identity is avoided.

Specifically, the specific information of the investment project includes project introduction, project amount, project yield, project period, etc., and the rights and rules include qualification requirements of the investor, investment period, and profit allocation, etc. It should be noted that the investment projects published by the project parties may be invested by at least one investor, i.e. it does not limit the number of investors, and the investors may be one or more, which is determined according to the project requirements of the actual project parties and the investment interests of the investors. When the investment project is invested, the project party can respectively negotiate the problems of investment amount and income distribution and the like with each investor, and different investors can have different investment amounts, investment periods and income distribution, for example, a larger investor can invest large investment amounts, long investment periods and high income ratio, and a smaller investor can invest small investment amounts, short investment periods and low income ratio; meanwhile, the method can dynamically determine the profitability, the distribution mode and the like according to the actual earning condition of the investment project in the implementation process, the investment mode of the investor and the like, and the method is determined according to the investment agreement actually established by the project party and the investor, and is not particularly limited.

Further, in one embodiment of the present invention, after the investment project management platform obtains the investment project registered and submitted by the project party, the submitted investment project is audited, wherein the relevant information of the investment project, the credit rating and financial report of the project party and other data are mainly audited to determine the authenticity and security of the project party and the investment project thereof, and then the investment project and the auditing result thereof are issued to the blockchain after the auditing is completed, wherein the blockchain can be implemented by using a public chain such as an ethernet or a alliance chain, so that the blockchain records the relevant information of the investment project and the authority and rules of the investment party and the project party defined by the project party, and it is pointed out that the investment project management platform can also issue each investment project, so that the investment party can directly screen the required investment project through the investment project management platform.

In particular, in order to facilitate understanding, the blockchain technique will be briefly described below, where the blockchain technique is a distributed database technique that may divide data into a plurality of small blocks, each of which includes records of transactions or events, and hash values of previous small blocks, and then concatenate the small blocks in time order to form an ever-increasing chain, called a blockchain. The data on the blockchain is commonly maintained and verified by a plurality of nodes in a Peer-to-Peer (P2P) network, each node has a complete blockchain copy, when a new transaction or event occurs, the data is broadcast to all nodes, then consensus is reached among the nodes, the new data is packaged into a new small block, and the new small block is added to the end of the blockchain. In this way, the data on the blockchain can be guaranteed to be public and transparent, and any person can view and trace back. At the same time, it is also ensured that the data on the blockchain is not tamperable and irreversible, as any modification to the existing data will result in a subsequent small block of mismatched hash values, and thus rejected and excluded by other nodes in the peer-to-peer network. Meanwhile, any one or more nodes of the peer-to-peer network are paralyzed, so that data on the blockchain cannot be lost, the blockchain data has strong security, and the data is ensured to be permanently stored and cannot be tampered.

Further, in one embodiment of the present invention, the investment project management platform may further utilize artificial intelligence algorithms such as machine learning and deep learning to analyze and evaluate each investment project submitted by all project parties, and make evaluation decisions on the investment projects based thereon. That is, the investment project management platform can evaluate the investment project registered and submitted by the project party to obtain the investment risk. Specifically, the method comprises the following steps:

The method is specifically realized as follows: firstly, data acquisition and processing are carried out, and information such as historical data, market data, financial data and the like of each investment project is obtained through a data mining technology, and the data are preprocessed and cleaned; secondly, carrying out feature extraction, namely carrying out feature extraction on data by utilizing a machine learning technology, such as classification, clustering, regression, recommendation and other algorithms of machine learning, and analyzing various features and indexes of investment projects, such as project types, scales, risks, benefits, progress, evaluation and the like, so as to facilitate subsequent modeling and prediction; then, model building and training are carried out, specifically, analysis and evaluation decision-making models are built according to the characteristics and indexes of each investment project through deep learning and machine learning technologies, and model training and optimization are carried out; and finally, predicting and deciding, namely predicting and evaluating the new investment project by utilizing the trained model, and evaluating the decision on the new investment project based on the predicting and evaluating the new investment project. The new investment project submitted by the project party is subjected to auditing evaluation to evaluate the investment risk of the investment project, so that corresponding investment suggestions can be provided for different types and asset investors, intelligent recommendation and decision support can be provided for the investors, and the investment efficiency of the investors can be improved.

Further, in one embodiment of the invention, the investment project management platform may also utilize artificial intelligence algorithms to credit rate the project parties. That is, the investment project management platform may credit rate the project party based on the outcome data of the historical investment projects of the project party. Specifically, when the project party submits and implements the investment project on the investment project management platform, the investment project management platform can analyze historical data about projects and funds, such as project progress monitoring, financial reports and the like, in each historical investment project of the project party through an artificial intelligence algorithm, so that credit rating is carried out on the project party, and intelligent recommendation and decision support can be provided for the investment party correspondingly based on the investment project, credit rating and the data of risk assessment and the like of the project party.

Step S20, acquiring registration information registered and submitted by an investor and completing identity authentication, so that the investor after the identity authentication acquires investment rights of investment projects and performs screening investment on each investment project on a blockchain;

wherein, in one embodiment of the present invention, when an investor needs to invest, the investor can know related information by looking at each investment project on the blockchain and conduct investment screening, however, at this time, the investor cannot directly invest in the investment project, and needs to register in an investment project management platform to realize docking communication with the investor and obtain the investment authority of the investment project. Specifically, if the investor does not register in the investment project management platform, the investor needs to register and fill corresponding registration information and perform identity authentication operation, and can perform docking communication and investment with the project party through the investment project management platform after the identity authentication is passed; if the investor registers on the investment project management platform, the investor can directly register on the investment project management platform, and after the identity authentication is passed, the investor can communicate with the project party in a butt joint way through the investment project management platform and invest. Specifically, the registration information includes personal identity information, asset proof, investment preference, investment capability and the like, and it is noted that if the investor is a person, the identity authentication operation is usually face identity authentication; if the investor is a legal organization, the identity authentication operation is generally to perform the authentication of the license first and then perform the face identity authentication of the responsible person. At the moment, the authenticity and the safety of personal identity information and asset certification of the investor are ensured by adopting an identity authentication technology for the investor. It should be noted that the above-mentioned investment rights are rights that the investor has the possibility of investing in the existence of each investment project, and do not represent that the investor is certain to be able to meet the qualification requirements of the investor defined in the rights and rules of the investment project by the project party.

Further, in one embodiment of the present invention, when an investor looks up each investment item on a blockchain or an investment item management platform and screens out investment items meeting own needs and preferences, the investor can initiate communication with the investor on the investment item management platform, and if the investor and the investor achieve an investment intention for the investment item, the investor can correspondingly negotiate to make an investment agreement. It should be noted that, the rights and rules of the investors and the project parties are the preset conceptual frame of the investment project, and the investment agreement is the actual clear content determined after the investors and the project parties communicate and negotiate, so that the investment agreement may be identical to or partially identical to the rights and rules of the defined investors and project parties, and is mainly determined according to the result of the communication and negotiation between the investors and the project parties, which is not limited herein.

Further, in other embodiments of the present invention, when an investor expresses an intent to invest in a certain project type in an investment project management platform, the investment project management platform automatically matches each project party meeting the conditions with the submitted investment project, so that the investor can screen the required investment project and communicate with the project party of the investment project.

Further, in other embodiments of the present invention, the investment project management platform may also automatically match qualified project parties and submitted investment projects according to the asset certificates, investment preferences and investment capabilities of the investors in the registration information. Namely, the proper investment and preferred investment items are matched and screened out according to the asset evidence, investment preference and investment capacity of the investor, the credit rating of each item party, each investment item and the assessed investment risk, and the investment items are recommended to the investor. Specifically, referring to the foregoing, the investment project management platform collects data such as credit rating, each investment project and assessed investment risk of each project party, and at this time, according to the asset evidence, investment preference and investment capability of the investment party, and the credit rating, each investment project and assessed investment risk of each project party, the investment project management platform matches and screens out the appropriate investment party asset and preferred investment project and recommends to the investment party, so that the investment party and its investment project suitable for the preference and requirement of the investment party can be matched and recommended, the satisfaction degree of the investment party is improved, for example, the investment party is robust in preference and insufficient in asset, and at this time, the project party and its investment project with high credit rating and low risk assessment can be matched. Further, in the above embodiments, when the investor looks up the investment project and the project side thereof, the investment project management platform may display the credit rating and risk assessment of the project side in addition to the relevant information of the investment project, so that the investor may also take into account the direct credit rating and the investment risk, and the investment project management platform may also provide investment suggestions and services for the investor for the screened investment project.

Further, in other embodiments of the present invention, the investment project management platform may perform credit rating on the investors according to the investment history, the profit situation and the credit records of the investors; when the communication between the investor and the project party is acquired, the credit rating of the investor is displayed to the project party, so that the project party can determine whether the investor needs to invest according to the credit rating of the investor. Specifically, the investment project management platform analyzes the investment history, the income condition, the credit record and other data of the investors through an artificial intelligence algorithm to realize the credit rating of the investors, at the moment, the credit rating result can be used as an important basis for the investors to participate in the investment project, and meanwhile, better screening service of the investors can be provided for the investors, and the investors can correspondingly determine whether the investors need to invest according to the credit rating result of the investors. Therefore, the investment parties with high credit rating can be screened out through the credit rating of the investment parties, and the success rate of investment projects is improved.

Step S30, acquiring an investment agreement established by a project party and an investor after the investment party achieves an investment intention on an investment project;

in one embodiment of the present invention, referring to the above description, when the project side and the investor reach the investment intention for the investment project, the investment agreement may be correspondingly negotiated to make the investment agreement, and the two parties may further make contract terms mainly composed of the investment agreement, where the investment agreement includes terms such as investment amount, yield and allocation mode, investment period, withdrawal mechanism, default punishment, and the like. Wherein the exit mechanism may be a mechanism for refunds or reimbursements negotiated by both parties to protect the investor's interests from loss when major changes or severe violations occur in the investment project. The default punishment can be any action of violating the contract, such as the project party submitting a progress report or proving results or the investor paying investment amount on time, etc., which occurs when the default punishment such as deducting a guarantee, ending the contract, etc. Specifically, the exit mechanism and the penalty can be determined according to the actual negotiation between the project party and the investor, and are not limited herein. And the investment protocol also comprises accounts of funds used by the investors and the project parties, so that the corresponding accounts can be clearly defined when the investors and the project parties transfer funds.

It should be noted that, when multiple investors invest in an investment project, the investment amount, investment period, profit allocation mode, exit mechanism, default penalty, etc. of each investor may be dynamically formulated, that is, may be the same or different, and are not specifically limited herein according to the investment agreement actually determined by the project party and each investor.

Further, after the investment project management platform obtains the project party and the investment agreement established by the investor after the investor achieves the investment intention on the investment project, the method further comprises the following steps:

respectively sending a signature request for signing the investment agreement to the project party and the investor so that the project party and the investor respectively sign the investment agreement by utilizing the private keys of the project party and the investor;

and issuing the investment agreement commonly signed by the project party and the investor to the blockchain.

Specifically, the investment project management platform sends signature requests to the project party and the investor, at this time, the project party and the investor sign the investment agreement by using private keys of the project party and the investor respectively, and send signed signature files to the investment project management platform, at this time, the investment project management platform can issue the investment agreement signed by the project party and the investor together to the blockchain, so that the authenticity and the integrity of the investment agreement can be ensured because the investment agreement passes through the common signatures of the project party and the investor, meanwhile, the investment agreement is prevented from being tampered or forged, and the conditions of funds and the like can be correspondingly processed according to the signed investment agreement issued on the blockchain when the implementation of a subsequent investment project is completed or abnormal, and the problems of information asymmetry, trust loss and the like in the existing investment project management are solved due to the untampere and high reliability of the blockchain technology, the decentralization trust between the investor and the project party is realized, and the transparency of investment is improved.

Step S40, creating an intelligent contract according to an investment protocol, wherein the intelligent contract is divided into a core layer responsible for processing key business logic and security attributes and an auxiliary layer responsible for processing non-key business logic and additional functions, the auxiliary layer is divided into a plurality of fragments, and each fragment is responsible for processing transactions of a part of the auxiliary layers;

further, in one embodiment of the present invention, the investment project management platform obtains the formulated investment agreement, and then formulates and composes the intelligent contract according to the investment agreement, that is, the intelligent contract is formulated and composed according to the investment agreement such as the investment amount, the yield, the investment period, the benefit distribution mode, the exit mechanism, the default punishment and the like. In particular, in order to facilitate understanding, the smart contract technology will be described briefly, where a smart contract is a computing protocol that is automatically executed on a blockchain, and may perform operations or transactions according to various preset rules and conditions without any intermediaries or trust authorities, and automatically trigger corresponding behavior operations when the preset conditions are met, so that data on the blockchain may not be merely records, but rather have logic and functions, thereby implementing more possibilities and values. The intelligent contract can realize automatic execution and non-falsification of the contract, and avoids errors and fraudulent behaviors of manual operation.

Specifically, the intelligent contract is written in a code form, the intelligent contract code is usually written by using intelligent contract development languages such as a solubility language and the like to realize the automation of each task, wherein the investment project management platform can provide corresponding contract templates, the investor and the project party only need to write necessary information such as investment amount, yield, investment period and the like into the templates, namely, the investor and the project party can write the investment agreement negotiated and formulated by the investor and the project party into the templates of the intelligent contract correspondingly to generate an intelligent contract meeting the willingness of both parties, thereby completing the writing of the intelligent contract, and the specific investment project management platform mainly writes the relevant information of the investment project and the contract clause formed by the investment agreement into the intelligent contract in a code form. At the moment, the intelligent contracts can be used for defining and executing various stages of investment projects, including project money transfer, progress report, return distribution and the like, and the functions of project management and money management are realized, so that the fairness and the credibility of the subsequent execution process are ensured, and meanwhile, the intelligent contracts can ensure the automation and the non-falsification of contract terms, and human intervention and dispute are avoided.

Wherein, in one embodiment of the present invention, the above-mentioned intelligent contract creation according to the investment agreement can be realized by the following steps:

when no abnormal result is detected, the intelligent contract is created.

Specifically, before designing the intelligent contract, selecting a proper intelligent contract template according to the type and the scale of the investment project, wherein the template comprises general or predefined conditions and events and customizable or selectable conditions and events; and then modifying and supplementing the intelligent contract template, adding or deleting some conditions and events or adjusting parameters and logics of some conditions and events according to the related requirements in the investment agreement of the investment project so as to meet the management requirements of the investment project. After modifying and supplementing the smart contract template, the smart contract is tested by a test function that simulates the different inputs and outputs to check if the smart contract meets the expected functions and effects. Specifically, firstly, static analysis is carried out on the source code in the process of compiling the intelligent contract source code into the byte code, whether common security holes exist or not is detected, such as code reentry, integer overflow, short address attack and the like, and warning or error prompt is given when the holes are found. Performing formal verification on the compiled byte codes, performing formal modeling on functional correctness and safety attributes of the intelligent contracts by using a logic language, and checking whether the intelligent contracts meet preset specifications and properties and whether common vulnerability types exist or not by mathematical reasoning and proving; to verify functional correctness and security attributes of the smart contract, such as whether expected business logic is met, whether there is a potential risk of denial of service, race conditions, etc., and to give a warning or error indication if the verification is not passed. And then dynamically analyzing the intelligent contract, generating a large amount of random or symbolized input data by utilizing the techniques such as fuzzy test, symbol execution and the like to form executable transaction, referring to the feedback of the test result, dynamically adjusting the generated data to explore the state space of the intelligent contract, monitoring whether abnormal results exist or behaviors which violate safety rules, such as predictable random processing, time stamp dependence and the like, and recording and reporting when problems are found. And when the loophole or abnormal condition is found in the static analysis, formal verification or dynamic analysis, modifying or optimizing the intelligent contract, and repeating the steps until the loophole or abnormal condition is not found, so that the intelligent contract is finally built. By combining the advantages of static analysis, formal verification and dynamic analysis, the intelligent contract can be ensured to be absolutely correct within a certain range, more possible input and state spaces can be explored, the coverage rate and the accuracy of detection are improved, and the high efficiency and the comprehensiveness of intelligent contract safety detection are realized.

Further, in one embodiment of the present invention, the intelligent convergence is divided into a core layer and an auxiliary layer. The core layer relates to key business logic and security attributes such as fund distribution, project progress, project quality, reward and punishment mechanisms and the like among the sponsor, the project party and the third party service provider, and the auxiliary layer relates to non-key business logic and additional functions such as project execution, project supervision, data analysis, user feedback, task distribution, cooperative communication, data sharing and the like among the project party and the third party service provider. The auxiliary layer is divided into a plurality of fragments, and each fragment is responsible for processing the transaction of a part of the auxiliary layers; such as transactions performed by one shard processing item, transactions supervised by another shard processing item, transactions analyzed by yet another shard processing data, etc. The number and size of the fragments can be dynamically adjusted according to the types, the number, the priority and the like of the transactions.

Step S50, respectively deploying a core layer of the intelligent contract on a main chain and an auxiliary layer on a side chain, establishing a cross-chain communication mechanism between the main chain and the side chain, performing cross-chain verification and execution, and establishing an internal communication mechanism between the side chain and the fragments, performing internal verification and execution;

Wherein, in one embodiment of the invention, the backbone refers to a public, consensus, non-tamperable blockchain for storing basic information and status of investment projects; while the side chain refers to a private, customizable, extensible blockchain for performing specific tasks and logic of investment projects. By disposing the core layer on the main chain, the core layer is guaranteed to be untampered and traceable; the auxiliary layer is deployed on the side chain, so that the auxiliary layer is flexible and extensible.

Further, by establishing a cross-link communication mechanism between the main chain and the side chain through an anchoring mechanism, data synchronization and coordination between the core layer and the auxiliary layer are realized, and cross-link verification and execution are performed when necessary. For example, after the project party receives enough investment, the auxiliary layer on the side chain is informed to start project execution through the cross-chain communication mechanism, and corresponding verification and execution are performed on the side chain. After the project party or the third party service provider completes the project task, the core layer on the main chain is informed to release corresponding execution rewards through a cross-chain communication mechanism, and corresponding verification and execution are carried out on the main chain.

By establishing an internal communication mechanism between the side chains and the fragments, data exchange and cooperation between the auxiliary layers are realized, and internal verification and execution are performed as necessary. For example, after the project side or third party service provider submits the task proof material, it is sent to the corresponding sponsor via an internal communication mechanism and the corresponding verification and execution is performed on the corresponding tile. After the investor submits the supervision report, the supervision report is sent to the corresponding data analyzer through an internal communication mechanism, and corresponding verification and execution are carried out on the corresponding fragments.

Further, in one embodiment of the present invention, the establishment of the cross-link communication mechanism between the main chain and the side chain and the cross-link verification and execution can be achieved by the following steps:

creating an anchor contract on the main chain, wherein the anchor contract stores addresses of side chains, public keys and hash functions, and provides an interface for receiving and sending cross-chain messages;

More specifically, in one embodiment of the present invention, the above specific implementation of performing cross-chain verification and execution may be varied, and the following is one possible example:

an authentication function is set in the anchor contract on the backbone, receives a cross-link message as input and returns a boolean value as output indicating whether the cross-link message is valid. The specific logic of the function can be designed according to different service requirements and security requirements, for example, whether the source of the cross-link message is an auxiliary layer on a side chain, whether the cross-link message is sent by an anchor node, whether the correct digital signature is contained, whether the preset format and content are met or not can be checked;

an execution function is set in the anchor contract on the main chain, the execution function receives a cross-link message as input, and according to the content of the cross-link message, the core layer on the main chain is controlled to execute corresponding operations, such as releasing or deducting funds, updating the state of funds, sending a credit or debit message and the like. The specific logic of the function can also be designed according to different business requirements and safety requirements, for example, whether the content of the cross-link message accords with contract terms, whether the corresponding condition is met, whether the sufficient fund balance exists or not can be checked;

An event monitor is arranged in an anchor contract on the main chain, and is responsible for monitoring a cross-chain message from an auxiliary layer on the side chain, and calling a corresponding verification function and an execution function according to the type and the content of the message. For example, if a cross-chain message reporting project progress is received, a validation function is invoked to validate it and an execution function is invoked to give a corresponding punishment.

As a specific example of the implementation manner, for example, after the investment direction is shifted to the core layer on the main chain, the core layer distributes the funds to the project party and the third party service provider, and sends a cross-link message to the auxiliary layer on the side chain through the anchor contract to inform that the funds are paid out, and information such as the funds distribution proportion and the address is attached. After the anchor node monitors that the anchor contract sends a cross-link message, an instruction or data is sent to the auxiliary layer on the side chain according to the message content. The instructions or data contain information such as the addresses, digital signatures, funds distribution ratios, and addresses of the sponsor, project party, and third party service provider. After receiving the instruction or data sent by the anchor node, the auxiliary layer on the side chain creates a corresponding sub-account on the side chain according to the fund distribution proportion and the address, and sends a cross-chain message to the anchor contract to confirm that the anchor contract has received the fund, and attaches information such as the sub-account address. The cross-link message contains information such as addresses, digital signatures, sub-account addresses, etc. of the sponsor, project party and third party service provider. After the anchor contract monitors the cross-link message sent by the auxiliary layer on the side chain through the event monitor, the anchor contract calls a verification function to verify the validity of the cross-link message, wherein the verification function verifies the validity according to the source, the digital signature, the format and other factors of the cross-link message, transmits a verification result and the cross-link message to an execution function, and the execution function updates the fund state according to the core layer on the control main chain corresponding to the cross-link message and sends a confirmation message to an investor. The validation message contains information such as the addresses, digital signatures, funds distribution ratios, and addresses of the sponsor, project party, and third party service provider.

When the auxiliary layer of the project party on the side chain completes a stage of task, the auxiliary layer sends a cross-chain message to the anchor contract, reports the project progress of the anchor contract and attaches information such as related proving materials and the like. After the anchor contract monitors the cross-link information through the event monitor, the source and the effectiveness of the cross-link information are verified by calling a verification function, and information such as a verification result, a proof material and the like and the cross-link information are transmitted to an execution function, the execution function controls a core layer on a main chain to give corresponding rewards or punishments according to the cross-link information and a set rewarding and punishment mechanism, and sends a cross-link information to an auxiliary layer on a side chain through the anchor contract to inform the rewarding and punishment result, and information such as the amount and the address of funds released or deducted is attached. After receiving the cross-link information, the auxiliary layer increases or decreases corresponding funds in the sub-account on the side chain according to the reward and punishment result, and sends a cross-link information to the anchor contract to confirm that the sub-account has received the reward and punishment result and attach information such as balance of the sub-account. After the anchor contract monitors the cross-link information through the event monitor, the source and the effectiveness of the cross-link information are verified through the verification function, the verification result and the cross-link information are transmitted to the execution function, the execution function controls a core layer on a main chain to update the fund state according to the cross-link information, and a reddening or deduction message is sent to an investor.

Therefore, by means of the method, a cross-chain communication mechanism is established between the main chain and the side chain through an anchoring mechanism, data synchronization and coordination between the core layer and the auxiliary layer are achieved, data and funds are communicated, and consistency and safety of investment projects are guaranteed. Meanwhile, time-efficient cross-chain communication and cooperation between the main chain and the side chain can be realized, and the efficiency and the safety of investment project management are improved.

Further, in one embodiment of the present invention, the above-mentioned establishment of an internal communication mechanism between the side chain and the fragment and internal verification and execution can be achieved by:

dividing the auxiliary layer into a plurality of fragments on a side chain according to the transaction amount and complexity of the auxiliary layer, wherein each fragment is responsible for processing the transaction of a part of the auxiliary layer, and each fragment can have parameters such as respective block size, block discharging speed, consensus algorithm, transaction cost and the like so as to adapt to different business requirements and performance requirements;

a coordination node is arranged on the side chain and is responsible for establishing an internal communication mechanism between the side chain and the fragments, and the coordination node can be a special anchoring node, an independent node or a node consisting of a plurality of nodes;

An internal communication protocol is arranged on the side chain, defines the format, the content, the source, the destination, the signature and the encryption rule of the information among different fragments, and provides an interface for sending and receiving the internal information;

an internal communication network is arranged on the side chain and is responsible for transmitting internal messages among different fragments, and the internal messages are correspondingly processed according to an internal communication protocol, such as signature verification, data decryption, format checking and the like;

each of the fragments on the side chain is respectively provided with an internal communication module which is responsible for interacting with an internal communication network and carrying out corresponding processing on internal messages, such as signature data, encryption data, formatting data and the like, according to an internal communication protocol;

and each of the fragments on the side chain is respectively provided with a first event monitor, and the first event monitor is responsible for monitoring internal messages from other fragments and calling corresponding business logic or additional functions according to the type and the content of the messages. For example, if the first event listener receives an internal message of a task allocation result, then invoking a task allocation contract to receive the task and begin execution; if the first event listener receives an internal message of a collaboration communication result, a collaboration communication contract is invoked to receive data and exchange information.

More specifically, in one embodiment of the present invention, the above specific implementation manner of performing the internal verification and execution may be various, and the following is one possible example:

setting a routing function in a coordination node on a side chain, wherein the routing function receives a transaction of an auxiliary layer as input and returns a serial number of a fragment as output to indicate which fragment the transaction should be processed by; the specific logic of the function may be designed according to different routing strategies, for example, the appropriate fragment may be selected according to the type, content, source, destination, etc. of the transaction, or the transaction may be randomly or polled to be allocated to different fragments;

setting a forwarding function in a coordination node on a side chain, wherein the forwarding function receives a transaction of an auxiliary layer as input, determines a specific fragment according to a return value of a routing function, and forwards the transaction to the corresponding fragment; the function may also perform some pre-or post-processing of the transaction, such as encryption or decryption, compression or decompression, signing or verification of the transaction, before or after forwarding the transaction as desired;

an aggregation function is arranged in a coordination node on a side chain, receives data or feedback information from different fragments as input, and aggregates the data or feedback information into a unified data or feedback information as output; the specific logic of the function can be designed according to different aggregation strategies, for example, a proper aggregation mode can be selected according to factors such as the type, the content, the source, the purpose and the like of data or feedback information, or some encryption technology or consensus mechanism can be used for ensuring the correctness and the safety of an aggregation result;

And setting a second event monitor in the coordination node on the side chain, wherein the second event monitor is responsible for monitoring a cross-chain message from an anchor contract on the main chain or internal messages of other fragments on the side chain, and calling a corresponding routing function, a forwarding function and an aggregation function according to the type and the content of the message. For example, if the second event listener receives a cross-chain message informing of funds to account, then invoking a routing function to select a fragment and invoking a forwarding function to forward the message to the fragment; if the second event listener receives internal messages such as project progress reports and associated certification materials from different segments, then an aggregation function is invoked to aggregate them into a unified project progress report and associated certification materials, and a forwarding function is invoked to forward them to the anchor contract.

As a specific example of the above implementation, for example, when the project party needs to perform task allocation with the third party service provider, a task allocation transaction is sent to the coordination node, where the transaction includes information such as the address of the project party, a digital signature, task content, task requirements, and the like. After receiving the task allocation transaction, the coordination node calls a routing function to select a fragment, and calls a forwarding function to forward the transaction to the fragment. The routing function selects proper fragments according to factors such as task content, requirements and the like; the forwarding function encrypts and formats the transaction to ensure the security and consistency of the transaction. After the fragments receive the task allocation transaction, the internal communication module and the internal communication network interact based on an internal communication protocol, and operations such as decryption and verification are performed on the transaction so as to ensure the validity and correctness of the transaction. The sharding distributes tasks to third party service providers according to task distribution transaction logic and sends an internal message of task distribution results to the coordination node. The internal message contains information such as the address of the project party, the digital signature, the address of the third party service provider, the task number, the task status, etc. And after receiving the internal information of the task allocation result, the coordination node calls the aggregation function to aggregate the internal information into a unified task allocation result, and calls the forwarding function to forward the unified task allocation result to the project party. The aggregation function selects a proper aggregation mode according to factors such as different task numbers and states; the forwarding function decrypts and formats the internal message so as to ensure the safety and consistency of the internal message. After receiving the task allocation result, the project party interacts with the internal communication network based on the internal communication protocol through the internal communication module, and performs operations such as decryption and verification on the internal message so as to ensure the validity and correctness of the internal message. And the project party confirms that the task is successfully distributed to the third party service provider according to the task distribution result and starts to cooperatively communicate with the third party service provider.

Therefore, by the method, an efficient, safe and reliable internal communication mechanism is established between the side chains and the fragments, data exchange and cooperation between auxiliary layers are realized, and meanwhile, the parallelism and expandability of the auxiliary layers can be improved, and the congestion and delay of the auxiliary layers are reduced.

Therefore, in the embodiment of the invention, the balance and the scalability of intelligent contract optimization are realized by layering and slicing technical means, the structure and the operation mode of the intelligent contract can be flexibly adjusted according to different service demands and scenes, and at the moment, different projects can be executed on different side chain layers without mutual interference or resource competition. Simultaneously, by stripping non-critical business logic and additional functions from the main chain and carrying out parallel processing on the side chains, the burden and the congestion on the main chain are reduced, the operation efficiency and the performance of intelligent contracts are improved, the transaction cost and delay are reduced, and the user experience and satisfaction are improved; meanwhile, through adding some functions which are not supported or inconvenient to realize on the main chain, such as privacy protection, data analysis, user feedback and the like, in the auxiliary layer, the effect and the value of investment project management are enhanced, and the functional richness and the flexibility of the intelligent contract are increased.

Step S60, the transaction information is sent to the investor, so that the investor uses a digital wallet to conduct transaction according to the transaction information to transfer funds to an address appointed by the intelligent contract, and then the intelligent contract is automatically executed;

in one embodiment of the present invention, after the investment project management platform completes the creation of the intelligent contract and deploys the core layer of the intelligent contract to the main chain and deploys the auxiliary layer to the side chain respectively, the start of the execution of the intelligent contract needs to be controlled, specifically, the execution of the intelligent contract is completed by a node on the blockchain network, when the intelligent contract is created, the intelligent contract is compiled into byte codes and issued to the blockchain network, the execution of the intelligent contract needs to be triggered by a transaction, at this time, an investor needs to transfer funds to an address designated by the intelligent contract, that is, an account for receiving funds of the investor is set in the intelligent contract, and when the transferred funds reach an investment amount determined in the intelligent contract, the intelligent contract automatically activates the investment project to perform the automatic execution of the contract clauses, and the execution result is saved on the blockchain.

Wherein during the investment process, the investor may have a digital wallet, wherein the digital wallet may use an open-source wallet application or self-development, which may be run on a mobile device or computer, and provide a set of public and private key pairs. The private key is stored only on the investor's device for signing the transaction, so that the authenticity and integrity of the transaction can be ensured by digital signature techniques, where once the transaction is signed, it cannot be tampered with or revoked. The public key is used for verifying the signature, so that the private key and sensitive information of the investor can be protected by using the digital wallet, and the safety and the credibility of the transaction are improved. Accordingly, the project party may also have a digital wallet such that subsequent smart contracts may transfer funds for the investment project into the project party's digital wallet and the project party may transfer the amount of revenue generated by the implementation of the investment project to the address specified by the smart contract at the end of the investment project to facilitate subsequent allocation of revenue by the smart contract.

In one embodiment of the present invention, the investment project management platform sends transaction information to the investor, the transaction information including the investment amount and the address specified by the smart contract, and the investor transfers funds to the address specified by the smart contract by using the digital wallet to conduct a transaction according to the transaction information. The method can be realized by the following steps: 1. creating a transaction according to transaction information, and appointing information such as a sender, a receiver and transfer amount of funds, wherein the sender is a digital wallet of an investor, the receiver is an address appointed by an intelligent contract in the transaction information, and the transfer amount is the investment amount in the transaction information; 2. the sponsor signs the transaction by using the private key of the digital wallet, broadcasts the signed transaction to all nodes in the blockchain network, and verifies and packages the transaction through special nodes on the network; 3. nodes in the blockchain network verify whether the signature is valid or not, and check whether the transaction accords with rules and restrictions of a blockchain protocol, and the transaction can be confirmed when the signature is valid; 4. funds will be transferred from the digital wallet of the sponsor to the address specified by the smart contract; 5. when a transaction is validated, it is added to the blockchain and a new blockchain is generated by a workload certification mechanism, wherein each new blockneeds to be validated by complex mathematical problems and validated by a consensus mechanism of the network node, once the new blockchain is added to the blockchain, the transaction is considered permanent and cannot be modified or deleted. At the moment, the investor invests by using the digital wallet, and ensures the safety of the transaction by the digital signature technology, so that the safety and reliability of the investment project are improved, and better investment experience is provided for the investor.

Step S70, performing project management and fund management of the investment project by utilizing automatic execution of the intelligent contract, and automatically distributing benefits of the investment project to an investor and a project party by utilizing the intelligent contract according to an investment agreement when the end of the investment project is determined according to the execution state of the intelligent contract;

in one embodiment of the present invention, after the intelligent contract is issued to the blockchain and automatically executed, the investment project management platform can implement project management and fund management of the investment project by using the intelligent contract, so as to ensure smooth progress of the investment project and rights protection of the project party and the investor. The project management comprises the functions of project progress management, staged result management, project party and investor rights and interests protection and the like; the fund management comprises functions of fund circulation, fund distribution, fund supervision and the like. Specifically, the project side begins executing the investment project according to the tasks and objectives defined in the smart contracts, and periodically submits project progress reports and related certification materials to the smart contracts. The third party service provider may also provide related services and ratings to the intelligent contracts based on its own responsibilities. The intelligent contract automatically verifies the project progress and quality according to the submitted information, and gives corresponding rewards or penalties according to a set rewards and punishment mechanism. For example, if a project party completes a phase of a task on time and reaches an intended goal, the smart contract will automatically release a portion of funds to the project party and give a proportion of the funds to the sponsor; if the project party delays or does not reach the standard, the smart contract deducts a portion of the funds as fines and reduces or cancels the equity to the sponsor. The intelligent contract can automatically execute contract clauses and automatically trigger corresponding operations when preset conditions are met. For example, when the intelligent contract receives enough investment amount, the investment project is automatically activated, funds are transferred to the project party, so that the project party starts to implement the investment project, when the project party submits a progress report and passes the audit of the investment party, the intelligent contract automatically releases funds of the next stage, an investment threshold value, a funds flow rule and the like can be set by the intelligent contract, and when the threshold value is reached, the next operation of the investment project such as paying income, transferring funds and the like is automatically triggered, so that the allocation management of funds can be automatically executed, the execution efficiency of the investment project is improved, and the problem of the project party for stealing funds can be effectively avoided through the execution of the intelligent contract.

Meanwhile, the progress of the investment project is determined according to the execution state of the intelligent contract and is synchronized to the investor and the project party, the specific intelligent contract can also automatically record the progress situation of the investment project by setting specific conditions and rules, the project party is required to periodically submit progress reports and achievement certificates to verify the progress, so that the record and verification of the workload are realized, the transparency and traceability of the investment project are ensured by automatically recording the progress situation of the investment project, and therefore, the automation and standardization of each task can be realized in the execution process of the intelligent contract.

Specifically, the intelligent contract can automatically record the progress condition of the investment project by setting specific conditions and rules, and can be realized by the following methods: 1. setting a time stamp: in the smart contract, a time stamp may be set to record the time of each operation, so that the progress of the investment project is known by automatically recording the time of each operation. 2. Setting state variables: in a smart contract, state variables may be set to record the state of an investment project. For example, a state variable may be set to represent the current progress of the investment project, the use of the investment money, etc., so that by querying the state variable of the smart contract, the execution and progress of the investment project may be determined, and the state variable may be automatically updated each time the investment project progresses. 3. Setting an event: in a smart contract, events may be set to record important operations. For example, when an investment project completes a certain important stage (e.g., start-up of the project, completion of a certain stage, occurrence of an abnormality, etc.), an event may be triggered to record the operation, so that important changes and progress of the investment project are known by monitoring events of the smart contract.

Further, in one embodiment of the present invention, the step of determining the progress of the investment project according to the execution status of the smart contract and synchronizing the progress of the investment project with the investor and the project party includes:

monitoring state variables or events set in the smart contracts;

Specifically, after determining the progress of the investment project according to the intelligent contract, the investment project management platform can analyze the progress of the investment project, and synchronize the progress and analysis to the investor and the project party according to whether the execution of the investment project accords with the expectation or not, so that when the execution of the investment project is not as expected, the investor can supervise the project party and take measures in time to solve the problem, and the problem of influence on the investor caused by the overtime of the execution of the investment project is avoided. Meanwhile, the investor can actively monitor the execution conditions of the investment project through the intelligent contract, including the fund flow direction, project progress and the like, so as to ensure the normal execution of the investment project and the interests of the investor. In addition, the investor can also give instructions to the project party through intelligent contracts, such as requiring the project party to publish more information, propose a change scheme, etc. At this time, the fairness and standardization of investment projects can be ensured through supervision of investors.

In other embodiments of the present invention, if an unpredictable or uncontrollable situation occurs during the process of investment project, and the original intelligent contract is no longer applicable or needs to be modified, the investor, the project party and the third party service provider can make a request for modifying the intelligent contract through a negotiation mechanism on the investment project management platform, and specify the modification reason and content. If all interested parties agree to the modification, validating and updating the smart contract by digital signature; if any party does not agree to the modification, then an independent third party arbitrator may decide whether to modify the smart contract and perform the arbitration result via an arbitration mechanism on the investment project management platform.

Specifically, the manner of modifying the intelligent contract through the negotiation mechanism and the arbitration mechanism can be realized through the following steps:

setting a negotiation contract on the main chain, the negotiation contract provides an interface for receiving and sending a negotiation request, a negotiation result and a negotiation confirmation message, and stores information related to negotiation, such as a negotiation initiator, a negotiation participant, a negotiation reason, negotiation content, a negotiation state and the like;

An arbitration contract is provided on the backbone, which provides interfaces for receiving and sending arbitration requests, arbitration results, and arbitration acknowledgement messages, and stores arbitration-related information such as arbitration initiator, arbitration participant, arbitration cause, arbitration content, arbitration status, etc. The arbitration contract also maintains a list of arbitrators, including address, public key, reputation, etc. information of the arbitrators, and provides interfaces for registration, cancellation, selection, evaluation, etc. operations;

when the investor, the project party or the third party determines that the intelligent contract needs to be modified, sending a negotiation request for explaining the reason of modification and the content of modification through the negotiation contract, broadcasting the negotiation request to all relevant parties, and storing the negotiation request in the negotiation contract;

after receiving the negotiation request, the related party replies the negotiation result through the negotiation contract, broadcasts the negotiation result to all the related parties after digital signature, and stores the negotiation result in the negotiation contract;

when all the related parties reply to agree to modify the negotiation result of the intelligent contract, sending negotiation confirmation indicating that the content is modified to the intelligent contract through the negotiation contract and broadcasting to all the related parties, and storing the negotiation confirmation in the negotiation contract;

The intelligent contracts update the intelligent contracts on the main chain and the side chains by the anchor contracts according to the modification content in the negotiation confirmation sent by the negotiation contracts;

when any party replies a negotiation result which does not agree to modify the intelligent contract, the party sends out an arbitration request which indicates arbitration reasons and arbitration contents through the arbitration contract and broadcasts the arbitration request to all relevant parties, and the arbitration request is stored in the arbitration contract;

after receiving the arbitration request, the relevant party replies an arbitration contract to indicate whether the arbitration result of modifying the intelligent contract is supported and broadcast to all relevant parties, and the arbitration result is stored in the arbitration contract;

after all the related parties reply to the arbitration result, an independent third party arbitrator is selected through an arbitration contract to send an arbitration request and an arbitration result, wherein the mode of selecting the arbitrator can be designed according to different strategies, for example, the arbitrator can be selected randomly or according to factors such as credit level, or the related parties can be voted to select the arbitrator;

when a third party arbitrator receives the arbitration request and the arbitration result, arbitrating whether to modify the intelligent contract according to the professional knowledge and judgment of the third party arbitrator, sending the arbitration result through the arbitration contract, broadcasting the arbitration result to all relevant parties through the digital signature, and storing the arbitration result in the arbitration contract;

After all the related parties receive the arbitration result, if the third party arbitrators arbitrate and modify the intelligent contract, all the related parties send arbitration acknowledgements through the arbitration contract and broadcast the arbitration acknowledgements to other related parties through the digital signature, and the arbitration acknowledgements are stored in the arbitration contract;

the intelligent contracts update the intelligent contracts on the main chain and the side chains by the anchor contracts according to the arbitration content in the arbitration acknowledgement sent by the arbitration contracts, and the arbitration process is ended;

if the third party arbitrator cuts and never modifies the intelligent contract, all related parties send arbitration confirmation through the arbitration contract and broadcast to other related parties after digital signature, and the original intelligent contract is maintained unchanged to finish the arbitration process.

In particular, in one embodiment of the present invention, the above-described manner of updating the smart contract may be implemented mainly by a proxy mechanism, so that the smart contract may update its logic while maintaining the address unchanged, and thus may modify parameters or suspend the original smart contract by deploying a new smart contract. The proxy mechanism is used for separating logic and data of the original intelligent contract and managing and calling the original intelligent contract through one proxy contract, so that transparent proxy of the original intelligent contract is realized. When the intelligent contract is required to be upgraded, only a new intelligent contract is required to be deployed, and a new address is pointed through the proxy contract, so that seamless switching is realized, and dynamic upgrading and maintenance of the intelligent contract can be realized on the premise that the original intelligent contract function and safety are not affected. As one example of the present invention, the proxy mechanism is essentially by first separating the logical code (i.e., functions and events) from the data code (i.e., state variables and constants) in the original smart contract and deploying it into a separate logical contract; separating the data codes in the original intelligent contracts from the logic codes and deploying the data codes into an independent data contract; and deploying an agent contract, wherein the agent contract can store addresses of the logic contract and the data contract and provide an interface for unified management and invocation. When the intelligent contract needs to be upgraded, a new logic contract or data contract is deployed, and the corresponding new address is updated through the proxy contract, so that the original intelligent contract is upgraded.

In this way, during the investment project, if unpredictable or uncontrollable situations occur, which result in the original intelligent contract no longer being applicable or requiring modification, the sponsor, project party and third party service provider can make a request to modify the intelligent contract through the negotiation mechanism on the blockchain platform, and specify the reason and content of modification. If all interested parties agree to the modification, validating and updating the smart contract by digital signature; if any party does not agree to the modification, then an independent third party arbitrator may decide whether to modify the smart contract and perform the arbitration result via an arbitration mechanism on the blockchain platform. Thus, the flexibility and fairness of investment project management can be ensured.

Thus, in embodiments of the present invention, investment project management is achieved through the use of blockchain technology and intelligent contract technology based on blockchain technology, such that investors can view their own investment projects on the blockchain, as well as the progress of the investment projects. The transparency and the safety of the investment project are ensured, the decentralised data storage and the untampered data recording can be realized, the safety and the integrity of the investment project data are ensured, and in addition, the problems of single-point fault, data tampering and the like can be avoided through the decentralised characteristic of the blockchain technology.

Further, in one embodiment of the present invention, after the project party submits the final result proof to the intelligent contract after the investment period is finished and transfers all the profit funds generated by the investment project implementation to the address designated by the intelligent contract, the intelligent contract can automatically allocate the profit according to the final project result and the profit, particularly allocate the profit to the investor, the project party and the third party service provider according to the rule defined when the investment agreement is written, and break up the contract after the investment project is finished. Wherein all transaction records and project information are permanently stored on the blockchain for viewing and verification by all interested parties. Further, in other embodiments of the present invention, when the investment project management platform determines that there is an default behavior of the project party or the investor in the implementation process of the investment project according to the intelligent contract, the intelligent contract is utilized to execute the default punishment in the investment agreement, and the punishment is synchronized to the project party and the investor. That is, in the implementation process of the investment project, if any action violating the contract occurs, such as the project party does not submit a progress report or a result proof on time, or the investment party does not pay the investment amount on time, the intelligent contract automatically executes penalty measures correspondingly specified in the investment agreement, such as deducting a guarantee, ending the contract, and the like.

Thus, all information and transactions for an investment project, including project applications, audit results, contractual content, funds flow, progress reports, outcome acceptance, return distribution, etc., can be recorded and stored throughout the investment project management process using blockchain technology. So that it is ensured that the information and transactions of the investment project are not tamperable, falsified, or deleted, while all participants are allowed to view and supervise the status and progress of the investment project in real time.

Therefore, compared with the existing investment management method, the investment project management method in the embodiment of the invention has the following beneficial effects:

through the blockchain technology, the intelligent contract technology and the digital signature technology, the non-tamper property of data, the non-credit property of transaction and the confidentiality of information can be ensured, the intervention and the fraud of intermediaries are avoided, the interests of investors and project parties are protected, and the safety of investment project management is improved.

Through the blockchain technology, the data can be disclosed and traced, so that the investors and the project parties can check the state and income conditions of the investment project at any time, the trust and the confidence are increased, and the transparency of the investment project management is improved.

Through layering and slicing technology, balance and scalability of intelligent contract optimization can be achieved, the structure and operation mode of the intelligent contract can be flexibly adjusted according to different business demands and scenes, and at the moment, different projects can be executed on different side chain layers without mutual interference or resource competition. Simultaneously, by stripping non-critical business logic and additional functions from the main chain and carrying out parallel processing on the side chains, the burden and the congestion on the main chain are reduced, the operation efficiency and the performance of intelligent contracts are improved, the transaction cost and delay are reduced, and the user experience and satisfaction are improved; meanwhile, through adding some functions which are not supported or inconvenient to realize on the main chain, such as privacy protection, data analysis, user feedback and the like, in the auxiliary layer, the effect and the value of investment project management are enhanced, and the functional richness and the flexibility of the intelligent contract are increased.
