Description
Technical Field
The invention relates to the technical field of block chains, in particular to a block chain multi-level framework based on a storage application scene and an operation method thereof.
Background
In this application, the term "blockchain" is used to encompass all forms of electronic, computer-based distributed ledgers, including but not limited to consensus-based blockchain and transaction chain techniques, licensed and unlicensed ledgers, shared ledgers, and variations thereof.
The most widely known application of blockchain technology is the bitcoin ledger, but other blockchain implementations have been developed based on their architecture in the prior art. Although illustrated herein with reference to bitcoin for purposes of convenience and explanation, those skilled in the art will appreciate that the present invention is not limited to use with bitcoin blockchains, and thus any alternative blockchain implementation and protocol that results based on this "blockchain" technique and its concepts fall within the scope of the present disclosure.
A blockchain, as an electronic ledger, is implemented as a computer-based decentralized, distributed system consisting of a plurality of blocks, which in turn consist of a plurality of transactions. Each transaction is a data structure encoding a transfer of control of a digital asset between participants in the blockchain system, and each transaction includes at least one input and at least one output. Each chunk contains a hash of the previous chunk, so that the chunks become linked together to create a record that all transactions written to the chunk chain since the beginning of the chunk chain, can never be changed.
In order to write a transaction to the blockchain, the transaction must be "verified". The network node (miners) must perform work to ensure that each transaction is valid and to make invalid transactions denied to the network. That is, the software client installed on the node performs this verification work on the Unspent Transaction (UTXO) by executing its lock script and unlock script. If the execution of the lock script and unlock script evaluates to TRUE (TRUE), the transaction is valid and the transaction is written to the blockchain. Thus, in order to write a transaction to a blockchain, the transaction must: 1 is verified by a first node receiving the transaction, and if the transaction is verified, the node relays the transaction to other nodes in the network; 2 to a new block built by the miners; and; 3 mined, i.e. added to a public ledger of past transactions.
Although blockchain technology is well known for its application to cryptocurrency implementations, digital entrepreneurs have begun exploring cryptosecurity systems on which bitcoins are based and the application of data that can be stored on blockchains to implement new systems. It would be advantageous if blockchains could be used for automation tasks and processes that are not limited to the field of cryptocurrency. Such a solution would enable existing business network solutions to be upgraded with the advantages of blockchains (e.g., permanence of events, tamper-resistant logging, distributed processing, etc.).
One aspect of current state-of-the-art research is the application of blockchains in the implementation of "intelligent contracts". These intelligent contracts are computer programs designed to automatically execute machine-readable contracts or terms of an agreement. Unlike traditional contracts that will be written in natural language, intelligent contracts are machine-executable programs that include rules that can process input to produce results, and can then cause actions to be performed depending on those results.
The present invention combines various prior art concepts in order to provide an infrastructure for blockchain mechanism based storage services that can be provided between different parties. The technical problem faced in the art is that the current blockchain design cannot be directly applied in the storage service application scenario, and even if the blockchain design is reluctant to be adopted, the problem of serious performance delay still exists, thereby troubling those skilled in the art.

Detailed Description
It should be noted that, in the present application, the embodiments and features of the embodiments may be combined with each other without conflict. The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, shall fall within the scope of the present invention.
It should be noted that the terms "S1", "S2" and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," as well as any variations thereof, are intended to cover non-exclusive inclusions.
To address the deficiencies of the prior art, embodiments of the present invention provide a blockchain multi-tier architecture based on storage application scenarios that employs a P2P network architecture design to form a distributed architecture that shares work and tasks among interconnected computing devices in "nodes" or "peers" to form a decentralized network, enabling no individual computer to be designated as "hosting".
As shown in fig. 1 to fig. 2, in the block chain multi-hierarchy architecture based on the storage application scenario provided by the embodiment of the present invention, an existing block chain, such as a bitcoin chain, is used as a main chain, and two layers of side chains are designed, that is, a contract chain: managing a blockchain of intelligent contracts, and certifying the chains: and managing the block chain for storing the certificate so as to carry out capacity expansion storage on the intelligent contract and corresponding certificate information required to be stored in the main block chain transaction.
Specifically, the contract chain is attached to the main chain, and a plurality of contract chains can be formed according to business requirements initiated by user nodes, so that the contract chains correspond to all blocks on the main chain, and therefore, according to the growth and distribution conditions of storage tasks, the contract chains can be expanded flexibly and transversely, and high-concurrency storage tasks are borne. Further, the contract chain is used for maintaining and storing intelligent contracts and simultaneously carries a settlement task of storing the intelligent contracts, and the settlement is carried out in the trading contract by receiving the storage certification event from the certification chain.
And the proof strand, i.e., the side chain of the contract strand. Where there may be several chains of certificates under each contract chain, the number of chains of certificates depending on the number of storage nodes on the contract chain. Therefore, the storage task can be flexibly and transversely expanded according to the increase and distribution conditions of the storage task. Wherein after a storage node is assigned to a given chain of credentials, storage nodes under the same chain of contracts can only provide credentials on the given chain of credentials to form an ordered management. The certification chain is also responsible for recording the target certification information stored on the storage node and monitoring the stored target state change event, namely storing the certification event.
The change event comprises a content copy success or failure event, or an abnormal event such as off-line of a storage node and damage of a hard disk. These change events are reported to the contract chain, and trigger the intelligent contract on the contract chain to perform corresponding processing actions.
On the other hand, the chain of certification is tasked with verification services and monitoring services in the design. The authentication service responds to a storage attestation request of the storage node and stores a storage attestation result on an attestation chain. The monitoring service is used for monitoring the online state of the storage node, and if the storage node is offline, the offline event also needs to be stored on a certification chain, so that information is collected on any execution trend of a transaction executing party, and high reliability of the storage service is ensured.
Specifically, the invention provides a block chain multi-hierarchy architecture scheme based on a storage application scenario, which is based on a P2P network architecture and provides a distributed storage architecture based on a block chain technology, wherein the architecture can allow a network node (user node) initiating a storage demand and a network node (storage node) meeting the storage demand of the user node to perform node registration on a contract chain and form a supplier and a demander, so that a storage demand offer is initiated on the contract chain through the user node, a task scheduler calls the storage node meeting the storage demand to perform matching and transaction under the rule of an intelligent contract, and the certification chain is used for storing a storage certification event of a completed storage task given by the storage node, so that the intelligent contract can be verified and updated, corresponding information is recorded on each corresponding block chain, or a change event is reported to the contract chain, and a processing action of the intelligent contract on the contract chain is triggered, so as to ensure the stability and sustainability of the whole transaction.
Therefore, it can be seen that each independent contract chain and corresponding plural certification chains can be derived from the transaction contract of the storage service initiated by each user, so as to meet the requirement of the storage user for high concurrent storage tasks and form a stable, efficient and reliable transaction flow.
It should be noted that, in the design of the block chain, the block chain mainly serves the requirements of a user storage service scene, and depends on the main block chain as an economic foundation/support, so that the user node/storage node actually having storage requirements/supply performs node registration on the contract chain, and initiates storage requirement transaction on the contract chain, and the contract chain performs node registration on the main block chain and obtains a corresponding account, thereby forming a system framework in which the contract chain proxies the user node/storage node to initiate transaction and record to the main block chain, and finally each contract chain reports the main block chain to complete and record the balance transaction, thereby forming a third party transaction and payment management mode depending on the main block chain financial system.
In addition, since the blockchain technology is based on a transaction and verification system, in this embodiment, the contract chain requires a user node/storage node to perform a pre-charging operation to perform a matching use of the storage transaction service on the contract chain. And simultaneously, the user node and the storage node can also recharge the node account of the appointed contract chain on the main module chain through the node account of the user node and the storage node on the main module chain, the recharged assets can be transferred to the accounts of each user node and the storage node on the corresponding contract chain, and then the transaction and the consumption are carried out on the contract chain. Similarly, the assets earned by the user nodes or the storage nodes on the contract chain can also be brought up through the reverse operation, and are transferred back to the accounts of the user nodes or the storage nodes on the main block chain, so that the framework has higher commercial value.
To better explain the operation method under the framework, the transaction contract and the storage certification event are first defined under the embodiment:
wherein the transaction contract initiated by the user node comprises: recording an intelligent contract of storage targets of user nodes which are responsible for each storage node, wherein the intelligent contract further comprises: storing the target ID, the storage duration, the storage price, the user node ID, the storage node ID and the like. Meanwhile, the trading contract is recorded on a contract chain and cannot be freely altered.
And the storage attestation events given by the storage node to the chain of attestation include: successful replication of the storage target, persistent certification of the storage target, failure of content storage, friendly departure of the storage node, offline of the storage node and other changing events. These events need to be reported by the chain of storage certificates to the chain of contracts for corresponding processing.
For example, referring to fig. 3 to 6, in a preferred embodiment, the specific operation method of the blockchain multi-level architecture based on the storage application scenario includes:
1) And (3) signing a transaction contract:
s1, a user node creates a trading contract on a contract chain and initiates a storage demand offer, wherein conditions such as the size, the duration and the payable fee of the storage demand are given.

And S3, the user node sends the storage target to the matched storage node according to the address information of the storage node.
And S4, after the storage node finishes receiving the storage target, sending the storage target certification to the certification chain, and sending the storage target replication success event to the contract chain by the certification chain.
And S5, after the contract chain receives the storage proving event of successful copying of the storage target, the corresponding trading contract is changed to take effect.
2) Transaction contract retention:
s1, the transaction contract of the user node needs the storage node to continuously provide a storage target existence certification event to prove that the storage node continues to perform during the existence period.
S2, the storage node sends a storage target storage certification event to the certification chain, and the certification chain sends the storage target continuous certification event to the contract chain.
And S3, after the contract chain receives the storage target continuous proving event, continuously maintaining the validity of the corresponding trading contract.
3) Transaction contract rescheduling:
s1, if the storage node can not continuously provide the storage evidence to prove that the storage node continues to perform during the existence period of the transaction contract of the user node, the transaction contract is rescheduled, and the mortgage charge of the storage node is penalized.
Specifically, when the certification chain sends a failure event of the storage target to the contract chain, or an abnormal change event such as the storage node being offline, the contract chain will arrange the contract to enter a rescheduling state.
And S2, the dispatcher re-matches the existing storage nodes meeting the storage requirement size, duration and payable fee conditions according to the transaction contract requirements, updates the transaction contract after successful matching, and puts the mortgage fee of the newly matched storage nodes into the contract.
S3, the newly matched storage node selects a mode from the former storage node or other storage nodes stored with the storage target to obtain the storage target.
S4, after the newly matched storage node receives the storage target, the storage target certification is sent to the certification chain, and the certification chain sends the storage target replication success event to the contract chain.
And S5, after the contract chain receives the storage proving event of successful copying of the storage target, the corresponding trading contract is changed and is enabled to take effect again.
4) Transaction contract termination:
s1, the trading contract of the user node can be actively stopped by the user during the existence period, and the residual charge is returned to the account of the user node after the contract chain is settled according to the existence period.
S2, after the trading contract of the user node is expired, the trading contract is naturally terminated, and the storage node can obtain all income.
S3 the storage node cannot terminate the trading contract on its own initiative, but can send a friendly departure event to the contract chain through the certification chain, so that the trading contract is scheduled again, with the mortgage charge portion of the storage node penalized.
5) Trading contract revenue:
the S1 storage node can obtain the income obtained by the period of the existence as long as the normally stored storage proving event can be provided regularly during the existence period of the trading contract.
The S2 storage node may periodically or aperiodically extract available revenue from the trading contract, or may wait for a one-time extraction after contract fulfillment is complete.
In summary, according to the disclosure of the block chain multi-level architecture based on the storage application scenario and the operation method thereof, it can be seen that the scheme of the present invention has more flexibility and risk resistance compared with the centralized management of cloud storage in the prior art. The system framework can provide distributed storage service in a network, so that corresponding storage nodes are adapted through a contract chain according to the storage requirements of users to automatically facilitate storage transaction, meanwhile, in order to ensure the storage reliability, an intelligent contract is triggered through the change events of the storage nodes to ensure that the storage targets are automatically adapted and transferred under a preset mechanism, so that the transaction contracts of the users are continuously and reliably executed to form decentralized storage efficacy, spare storage resources in the network are fully utilized to obtain benefits, the focus attack risk stored in a certain centralized storage is avoided, the storage loss risk which can be met is reduced, and a high-reliability distributed storage resource allocation transaction framework is formed.
