Description
Technical Field
The invention belongs to the technical field of P2P file sharing technology and block chain application, and particularly relates to a nesting excitation method, a nesting excitation system and application of a distributed file sharing system.
Background
Currently, P2P file sharing is one of the most popular P2P applications. The P2P file sharing systems (e.g., BitTorrent, Napster, and Gnutella) have successfully attracted hundreds of millions of users. BitTorrent, one of the most successful P2P distributed file systems, supports over 1 billion online users. It has a large-scale deployment with thousands of nodes connected each day. Due to the fact that the number of nodes in the system is large, the behavior of taking a free car easily occurs under the condition that an incentive mechanism is not available. Nodes do not contribute when downloading resources greedily, resulting in an imbalance between uploading and downloading, causing other nodes to lose power for sharing as well. The greatest challenge of this system is therefore to provide incentives in an efficient, safe and practical manner.
There are many successful studies on P2P file sharing and its incentive mechanism today, such as the Tit-for-Tat policy, reputation management system or credit-based approach. From the above approaches, it can be seen that most reputation-based and credit-based incentive measures rely on a central trusted authority to improve efficiency and confidence. In the actual P2P system, it is difficult to find a third party trusted authority, which brings difficulties to the efficient and reliable implementation of the incentive scheme. The distributed technology of the block chain provides a potential solution for the distributed technology. Nakamoto published his famous paper in 2008, which introduced a practical blockchain consensus protocol, later referred to as bitcoin protocol. The protocol realizes a set of mechanism, so that nodes which are not trusted mutually can achieve consensus and jointly maintain an account book. The node uses the bitcoin to trade, the trade record confirmed by the account book can not be modified, and the consensus can be achieved without a third-party trusted institution. The first generation blockchain is primarily used as a decentralized digital distributed book for economic transactions until intelligent contracts emerge.
The intelligent contract is a script language embedded in a blockchain network and can provide rich functions. EtherFang is one of the most representative intelligent contract platforms. The etherhouse executes stack-based turing-complete language and manipulates blockchain state using the Etherhouse Virtual Machine (EVM). Rights and obligations of participating nodes, conditions triggering contract execution, and corresponding results of execution are specified in the intelligent contract. Current smart contracts still cannot afford heavy computational tasks and storage loads.
Through the above analysis, the problems and defects of the prior art are as follows: current smart contracts still cannot withstand the heavy computational tasks and storage loads.
The difficulty in solving the above problems and defects is:
1. most incentive methods for solving the problem of taking a free car in the distributed file sharing system need a trusted third party organization for guarantee. However, in a distributed system, it is difficult to find a third party trusted authority to efficiently and reliably execute the incentive scheme.
2. The existing reputation and reputation incentive methods cannot achieve the circulation of incentives in the system, and only increase or decrease the reputation value singly. Once the reputation of the user is too low, the account can be abandoned directly, and the problem of taking a free car cannot be well solved
The significance of solving the problems and the defects is as follows: and (3) a nested incentive method is used, downloading resources are paid, and nodes which actively respond to transaction requests and help file propagation are rewarded. The problem of carrying a free car in the distributed file sharing system is better solved, so that the system user activity is high, and the benign operation of the system is maintained.

By combining all the technical schemes, the invention has the advantages and positive effects that: there is now much success in the research on P2P file sharing and its incentive mechanisms, such as reputation management systems and credit-based approaches. Reputation systems may help users identify uncooperative peers by monitoring the behavior of neighbors during data transmission and propagating uncooperative reputations in the network, such systems often lacking formal specification and analysis of incentive types and consideration of how to define the reputation of new users. Credit-based methods provide incentives by paying a certain amount of credit or virtual currency to collaborating users, which may be the most promising due to their clear and flexible incentive methods. Most reputation-based and credit-based incentive measures rely on a central trusted authority to improve efficiency and confidence. In the actual P2P system, it is difficult to find a third party trusted authority, which brings difficulties to efficiently and reliably implement the incentive scheme.
The invention solves the problem of no third-party trusted authority by using a block chain technology. The blockchain technique may reach consensus without a trusted third party. Cryptocurrency, as the original application of blockchains, may become the most efficient incentive for distributed file sharing systems. The downloading behavior of the file is replaced by purchasing behavior, and the downloading cost can eliminate the behavior of taking a free car. The creators get authoring incentives, the nodes that help document propagation get propagation incentives, the incentives can stimulate the nodes to create with high quality, are more willing to participate in the document propagation process, and can use the earned incentives on purchasing the required documents. This enables the incentive to be turned around in the system, forming a prototype of the incentive for currency based on block chains.
In the P2P file sharing system of the present invention, there are two kinds of file transferors, one is that the first nodes recruited by the author store files as primary providers, and the other is that the nodes that have subsequently purchased files participate in the propagation and transition to secondary providers. The invention aims to solve the problem that an effective incentive mechanism is lacked in a P2P file sharing system, and the nodes do not make any contribution to greedy underground resource-the behavior of carrying out a vehicle for convenience, so that other nodes are not willing to share, and a system user is inactive. The incentive mechanism is designed with the basic idea of rewarding nodes that respond positively to transaction requests to successfully transfer file blocks. And by utilizing a block chain and an intelligent contract technology, the automatic execution of incentive distribution is realized under the condition of no third-party trusted authority.

According to the embodiment of the invention, the author earns the creation incentive by selling the original works, recruits nodes by giving the transmission incentive to the author, stores and transmits the files as primary suppliers, reduces the storage pressure of the author, and enhances the transmission capability of the files. In a distributed file sharing system, files need to be transmitted in blocks, and an author needs to perform block encoding on the files.

Example 2
At the initial stage of file dissemination, only the primary supplier provides file dissemination when no secondary supplier is added to the file dissemination market.
The method comprises the following steps: the author carries out block encoding on the file Flie by using an error correcting code, divides the file Flie into 7 parts [ R1-R7], and needs 4 parts to recover the file Flie;
step two: 7 nodes are recruited as primary suppliers to respectively store file blocks, the primary supplier F1 stores file blocks R1, F2 stores R2, F3 stores R3, F4 stores R4, F5 stores R5, F6 stores R6, and F7 stores R7;
step three: the author sets the pricing of the file Flie to be 100Coin, sets the primary revenue sharing proportion to be 20%, and sets the total propagation incentive in each successful transaction to be 20Coin, wherein the incentive obtained by each file transmitter is 20/4-5 Coin;

step eight: the transmitters are all primary suppliers, and the primary suppliers F1, F2, F5 and F6 obtain complete propagation excitation 5 Coin;
example 3
The number of creators recruiting primary providers must exceed the number of recoverable files, as close as possible to the number of encoded redundancies
The method comprises the following steps: the creator divides the file, redundantly encodes the digital product into k parts, and can recover the k parts by n parts;
step two: the author broadcasts k file blocks;
step three: checking the response quantity of the nodes in T time;
step four: if the number of the primary suppliers does not meet the condition, broadcasting the rest file blocks again;
step five: if the number of the primary suppliers is larger than n and is close to k, stopping broadcasting;
step six: and repeating the third step to the fifth step until the condition is met.
The invention realizes the transmission excitation by using the block chain and the intelligent contract technology in an effective, safe and practical mode, and stops the behavior of taking the convenient car. The nested incentive mechanism attracts nodes to participate in the file transmission process, increases the activity of system nodes, and reduces the storage and bandwidth pressure of creators. After obtaining the incentive, the node can be used for purchasing files to realize incentive circulation in the P2P file sharing system.
The technical solution of the present invention is further described with reference to the following specific examples.
According to the theoretical analysis of the nested incentive model, the demand of a market on the digital product is considered firstly, the demand is increased rapidly in a certain time period, the demand is gradually reduced after the heat is passed, the market demand is influenced by time factors, and the market demand shows a trend of increasing first and then decreasing along with the change of time. Assuming that the propagation period of the digital product is [0, T ], the demand function can be expressed as:
D(t)＝A·t2·e-ηt (1)
a is the market demand rate which is not influenced by time; eta is the sensitivity coefficient of the demand to time; d (t) is the demand function.
Suppose a file transmitter TiUnder the transaction requirement at the time t, the probability of successful transaction is PtThen transmitter TiPropagation excitation obtained at time t
Comprises the following steps:
when the first supplier FiAs a transmitter TiTime, primary supplier FiPropagating excitation of
Is equal to transmitter TiExcitation of
When the second supplier SiAs a transmitter TiA nested excitation mechanism will be implemented. Primary supplier FiPropagating excitation of
And secondary supplier SiExcitation of
Respectively as follows:
then primary supplier FiTotal propagation excitation obtained at time t
Comprises the following steps:
propagation period [0, T ] in digital products]Inner, primary supplier FiObtained total propagation excitation INFiAnd secondary supplier SiObtained byTotal nested propagation excitation INSiRespectively is as follows:
it can be seen from the above formula that in the transmission process [0, T ], the transmission incentive of the primary supplier is divided into the incentive of the secondary supplier in addition to the part earned by the primary supplier. The nested incentive model can really ensure the benefit maximization of the primary suppliers and is more beneficial for the creators to recruit nodes as the primary suppliers. Nested incentives also encourage secondary providers to join document dissemination to obtain rewards, while also expanding the file dissemination capabilities.
