[ detailed description ] embodiments
For better understanding of the technical solutions of the present application, the following detailed descriptions of the embodiments of the present application are provided with reference to the accompanying drawings.
It should be understood that the embodiments described are only a few embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The terminology used in the embodiments of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in the examples of this application and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
Technical term interpretation:
main chain
The main chain refers to a formally online, independent blockchain network.
Side chains
The side chain refers to wedged side chain technology (sidechains), which is a relative concept for the main chain, and the english language is sidechains. The side chain concept is proposed mainly to realize the transfer of bitcoin and other digital assets between a plurality of blockchains, and simply, the side chain is a mechanism for moving the currency between two blockchains.
Intelligent contract
An intelligent contract refers to a computer protocol that enables self-execution (self-validation) and self-verification (self-verification) once formulated and deployed, and that does not require human intervention. From a technical point of view, an intelligent contract may be considered a computer program that autonomously performs all or part of the contract-related operations and produces corresponding evidence that may be verified to demonstrate the effectiveness of the contract operations. Before deploying the intelligent contracts, the logic flow of most of the terms related to the contracts is established. Intelligent contracts are typically provided with a user interface (interface) to allow a user to interact with the contracts that have been established, all in strict compliance with previously established logic.
The intelligent contract has the following advantages: (1) efficient real-time updating; (2) accurate execution is carried out; (3) lower risk of human intervention; (4) removing the centralized authority; (5) lower running cost.
Ether house
Etherhouse is a universal global block chain, as well as platform and programming languages, including digital currency ethernet (Ether), and ethernet scripts (EherScript) used to build and publish distributed applications. Additionally, from a bottom-level perspective, etherhouses are a multi-tiered, open source technology protocol based on cryptography. The different function templates of the system are comprehensively integrated through design, and the system is a platform for creating and deploying decentralized application as a whole.
Account
Each account is determined by a pair of private and public keys. Each account has an address.
Trading
A transaction refers to a signed data packet storing a message sent from an external account number. The transaction contains the recipient of the message, a signature to confirm the sender, the ethernet account balance, and/or the data to be sent, etc.
Status of state
Confirmed, unconfirmed, locked, unlocked, executed, and/or unexecuted transactions, etc.
Because all the intelligent contract operations are performed on the main chain in the current block chain, the number of times that the intelligent contract is operated is continuously increased along with the continuous increase of block chain users, and the operation resources of the whole block chain are limited, so that the intelligent contract is slow to operate, and even congestion is caused. For example, in an ethernet house, a large number of intelligent contracts are run, which results in slow running speed and high cost, for example, the gas cost of the ethernet house is higher and higher, which results in increased economic cost for users. In order to solve the above technical problems, embodiments of the present application provide a processing method based on a block chain intelligent contract, in which a side chain is added to perform operation on an intelligent contract, so as to implement shunting of intelligent contract operation on a main chain, thereby increasing a main chain operation speed and reducing a cost required by a user for operating the intelligent contract. As will be described in detail below.
Fig. 1 is a flowchart of an embodiment of a processing method based on a blockchain intelligent contract according to the present application. It should be noted that the block chain includes a main chain and at least one side chain, wherein the main chain and the matching side chain are generally in a unique corresponding relationship. The reason for the side chain setting is that when the main chain is temporarily unable to meet new requirements, the transaction operation on the main chain is transferred to the side chain, and after the transaction operation on the side chain is completed, the transaction information on the side chain can be completely transferred to the main chain.
Through the side chain, new functions such as intelligent contracts can be added on the basis of the main chain, and even if a large number of transactions need to run the intelligent contracts, the work influence on the main chain can not be caused. In addition, the side chain provides a safer protocol upgrade, and the main chain is not greatly influenced when the side chain has a catastrophic problem. In addition, it should be noted that, because the side chains themselves are independent block chains, there is a node network (accounting node, etc.) of themselves, and the codes and data are also relatively independent; therefore, the load of the main chain cannot be increased in the running process, and the condition of excessive expansion of data is avoided.
The technical basis for sidechain implementation is Two-way anchoring (Two-way Peg), by which temporary locking of digital assets in the main chain can be achieved while releasing equivalent digital assets in the sidechain. Likewise, when an equivalent digital asset is locked in a sidechain, the digital asset of the main chain may also be released. The current side chain generation modes include a single escrow mode, a federation mode, a Simple Payment Verification (SPV) mode, a drive chain mode, a hybrid mode and the like.
The processing method based on the block chain intelligent contract provided in fig. 1 may be applied to the application scenario shown in fig. 5, and fig. 5 is a schematic view of the application scenario of the processing method based on the block chain intelligent contract according to the present application.
Referring to fig. 1 and 5, the processing method based on the blockchain intelligent contract may include:
step 101: initiating a transaction on the main chain triggers the establishment of the sidechain;
step 102: deploying an intelligent contract on the side chain;
step 103: running the intelligent contract on the side chain to bill the transaction;
step 104: voting and verifying the operation result of the intelligent contract through the participants of the intelligent contract;
step 105: and transmitting the operation result after voting verification to the node of the main chain through the side chain.
In a preferred embodiment, the side chains in the block chain of the above processing method are ether house block chains. The Ethernet workshop is provided with an Ethernet virtual machine built on a block chain, and the intelligent contract writing becomes simple due to the introduction of the virtual machine. The Ethernet virtual machine is a code running environment established on an Ethernet workshop blockchain, is stored on each node computer, and runs the virtual machine by each check node participating in the Ethernet workshop network and takes the virtual machine as a part of a blockchain validity check protocol. Each node performs the same calculations for deployment and invocation of the intelligent contracts and stores the same data to ensure that the most authoritative and true results are recorded in the blockchain.
Fig. 3 is a schematic structural diagram of an embodiment of a processing system based on a block chain intelligent contract according to the present application, and fig. 4 is a schematic structural diagram of another embodiment of a processing system based on a block chain intelligent contract according to the present application, as shown in fig. 3 and fig. 4, in the embodiment of the present application, generation of a side chain 12 is triggered when a transaction is initiated on a main chain 11 (i.e., when transaction information on a transaction terminal is transferred to the main chain 11), that is, creation of a creation block in the side chain is based on whether a transaction is performed on the main chain or not. When the side chain is generated, a synchronization relationship between the side chain 12 and the main chain 11 is formed by a bidirectional anchoring technique such as a single escrow mode, a alliance mode, an SPV mode and/or a driving chain mode between the side chain 12 and the main chain 11. The synchronous relationship refers to the transaction information in the side chain 12 and the main chain 11, the running results of the intelligent contracts can be shared with each other, and the latest state is synchronously updated.
In addition, the creation of the first block in the side chain 12 may be a creation block generated independently from the main chain 11, or as shown in fig. 4, the first block side chain 01 in the side chain 12 may be served by the last block main chain End in the main chain 11. In this way, the combination and synchronization of the main chain 11 and the side chain 12 can be made simpler. Of course, in the embodiment of the present application, each main chain 11 may include a plurality of different side chains 12, and the different side chains 12 may have different functions, such as smart contract operation performed by one side chain 12, transaction security and/or information upgrading performed by another side chain, and the like.
With continued reference to fig. 1, in the embodiment of the present application, the operation of the intelligent contract on the main chain 11 is shunted to the side chain 12, so that the intelligent contract needs to be deployed on the side chain 12, and specifically, the following steps may be included:
(1) multiple users participate in making the intelligent contract together;
(2) diffusing and storing the intelligent contract into the side chain of the block chain through a point-to-point (Peer to Peer; hereinafter referred to as P2P) network;
(3) automatically executing the intelligent contract in the side chain.
Wherein, for the step (1), the method specifically comprises the following steps:
① firstly, the user must register as a user of the blockchain, and the blockchain returns a pair of public key and private key to the user, where the public key is the account address of the user on the blockchain and the private key is the only key for operating the account.
② at least two users agree on a commitment containing the rights and obligations of each party, the rights and obligations are recorded in electronic form in machine language, and the participants sign with their private keys to ensure the effectiveness of the contract.
③ the signed intelligent contract will be transmitted to the blockchain network according to the promised content therein.
Wherein, for the step (2), the method specifically comprises the following steps:
① the contract is diffused in the block chain whole network by the mode of P2P, each node receives one contract, the verification node in the block chain stores the received contract in the memory first, waits for a new round of consensus time, and triggers the consensus and processing of the contract;
② when the agreement is reached, the verification node will pack all the contracts stored in the last period into a contract set (set) and calculate the Hash (Hash) value of the contract set, and finally assemble the Hash value of the contract set into a block structure to be diffused to the whole network, after other verification nodes receive the block structure, the Hash of the contract set contained in the verification node will be taken out and compared with the contract set stored by themselves, and at the same time, a contract set approved by themselves will be sent to other verification nodes, through the multi-round sending and comparison, all the verification nodes will finally reach the agreement to the latest contract set in the stipulated time.
③ the latest contract collection will be spread to the whole network in blocks, each block contains the Hash value of the current block, the Hash value of the previous block, the timestamp when the consensus is achieved, and other description information, the most important information of the block chain is the one with a group of agreed contracts, the node receiving the contracts will verify each contract, the verified contract will be written into the block chain finally, the verified content is mainly whether the signature of the contract participant private key matches with the account.
Wherein, for step (3), specifically, the method may include:
① the intelligent contract will periodically check the state of the automaton, traverse the state machine, affairs and trigger condition contained in each contract, push the affairs with satisfied condition to the queue to be verified, wait for consensus, and keep storing the affairs without satisfying the trigger condition on the block chain.
② the latest round of verification transaction can be spread to each verification node (accounting node), as with the common blockchain transaction or transaction, the verification node first performs signature verification to ensure the validity of the transaction, the transaction passing verification enters the waiting consensus set, and after most verification nodes achieve consensus, the transaction will be successfully executed and inform the user.
③ after the affairs are successfully executed, the state machine of the intelligent contract judges the state of the contract, when all affairs included in the contract are executed in sequence, the state machine marks the state of the contract as completed and removes the contract from the latest block, otherwise, the state of the contract is marked as in progress and continuously stored in the latest block to wait for the next round of processing until the processing is completed, the whole affairs and the state processing are automatically completed by the intelligent contract system built in the bottom layer of the block chain, and the whole process is transparent and can not be changed.
Fig. 2 is a flowchart of another embodiment of the processing method based on a block chain intelligent contract according to the present application, and as for the voting verification process in step 105 in fig. 1, as shown in fig. 2, the running result of the intelligent contract is implemented by performing the voting verification process by the participants of the intelligent contract, where the participants of the intelligent contract include at least two users, and for the confirmation of the running result of the intelligent contract, all the users need to reach a agreement to perform the voting verification process. The specific steps may include:
step 201, voting and confirming the operation result of the intelligent contract through all the participants of the intelligent contract;
step 203 transmits the operation result of the intelligent contract to the main chain through the side chain when all intelligent contract participants approve the operation result.
In an embodiment of the present application, in step 202, when there is an disapproval of the participant of the intelligent contract with the operation result, the method may further include: and voting to confirm whether the current operation result needs to be operated again through the participants of the intelligent contract. If the participants of the intelligent contract vote to decide that the operation needs to be carried out again, step 203 is entered; if the participants of the smart contract vote to decide that no further execution is necessary, execution is terminated.
According to the method and the device, the participant of the intelligent contract carries out a voting confirmation mechanism on the operation result of the intelligent contract in the side chain, so that the accuracy of the operation result of the intelligent contract is confirmed, and the problem that each accounting node of the operation result of the intelligent contract needs to be confirmed in the related technology, and the calculation amount is huge is solved. According to the method and the device for processing the intelligent contract, the intelligent contract is operated on the side chain, the operation result of the intelligent contract is transmitted to the main chain, after the operation result transmitted by the side chain is received by the node of the main chain, the operation result of the intelligent contract is issued to all the nodes of the main chain through the node of the main chain, and the operation result of the intelligent contract is stored in the block chain, so that the intelligent contract is operated on the side chain, resources on the main chain are occupied, and the method and the device for processing the intelligent contract are efficient.

In this embodiment, when the main chain node 11 initiates a transaction on the main chain, the creation block is created in the side chain node 12, and the side chain node 12 and the main chain node 11 are anchored in two directions, so as to form a synchronization relationship between the side chain node 12 and the main chain node 11.
The last block in the main chain node 11 serves as the above-described founder block in the side chain node 12.
