Description
Technical Field
The invention relates to the technical field of block chains, in particular to a method for specifying an address when an Ethernet shop issues an intelligent contract.
Background
The intelligent contract is a set of commitments defined in a digital form, controls digital assets and specifies the rights and obligations of contract participants, the intelligent contract is automatically executed by a computer system, and the execution process of the intelligent contract is the processing process of data. In essence, smart contracts are the use of if-then (if-then) in a computer system to interact with real-world property. Although the intelligent contract concept was proposed earlier, the goal of intelligent contracts was difficult to achieve due to the lack of systems or technologies capable of supporting the intelligent contract feature.
An ethernet bay is a block chain implementation, and an intelligent contract is executable code on the ethernet bay, and the development of the intelligent contract is generally performed by using a truffle. Wherein, the truffle is a development framework of an Ethern.
The Blockchain (Blockchain) is an important concept of bitcoin, and the Blockchain is a series of data blocks which are generated by using a cryptographic method to be associated, and each data block contains information of all bitcoin network transactions in the past ten minutes, so that the information is verified to be valid (anti-counterfeiting) and the next block is generated. This concept is proposed in the white paper of the traditional Chinese clever, which has the first block, namely the "created block".
The latest technical application of the block chain is the bitcoin technology which appears in 2008 after the tire is removed, and the block chain provides a decentralized credit establishment paradigm without trust accumulation. The Block chain technology is essentially a decentralized and distributed structure data storage, transmission and certification method, the dependence of the internet on a central server at present is replaced by a data Block (Block), all data changes or transaction items are recorded on a cloud system, the self-certification of data in data transmission is realized theoretically, the data Block exceeds an information verification paradigm that the center is required to be depended on in the traditional and conventional meanings, the establishment cost of global credit is reduced, the point-to-point verification generates a basic protocol, the basic protocol is a novel form of distributed artificial intelligence, and a brand new interface and a shared interface of human brain intelligence and machine intelligence are established.
The Blockchain (Blockchain) technology is widely applied to the financial field due to the characteristics of decentralization, transparent and traceable transaction process and the like, and the barrier in the intelligent contract implementation process is perfectly solved due to the appearance of the Blockchain. Because the blockchain has the characteristics of decentralization, the transaction records are not falsifiable and can be tracked, the characteristics ensure the fairness of the execution of the intelligent contract, and the blockchain is an application program and can be interacted with by the intelligent contract. The advent of blockchains has enabled the rapid development of intelligent contracts, which are now widely used and one of the features of blockchain technology.
The intelligent contracts executed in the blockchain generally comprise two stages of deployment and execution, wherein a creator creates the intelligent contracts in the deployment stage and deploys the intelligent contracts on the blockchain, and the intelligent contracts deployed on the blockchain are visible to all persons due to the openness of the blockchain. In the execution phase, the block chain node acquires the intelligent contract to be executed, then acquires the processed data, and generally enables the intelligent contract to process the data in the environment similar to a virtual machine, then the block chain node performs consensus on the result, and returns the consensus result to the creator.
However, in the prior art, the address for issuing the intelligent contract in the blockchain by using the ether house is automatically generated by the system, and the transaction signed by the intelligent contract cannot be directly issued.
Disclosure of Invention
The invention aims to solve the problems in the prior art, and provides a method for specifying an address when an Ethernet shop issues an intelligent contract, which can directly send out a transaction signed by the intelligent contract and also can directly manage the balance of the intelligent contract.
In order to achieve the purpose, the invention adopts the following technical scheme:
a method for specifying an address when an Ethernet shop issues an intelligent contract comprises the following steps: creating an intelligent contract according to transaction requirements;
adding a flag bit attach in the created intelligent contract parameter;
the created intelligent contracts are issued to the block chain by utilizing the Ethernet;
the nodes in the block chain judge whether the issued intelligent contract is the intelligent contract of the designated address through the attach, if the flag bit of the attach is 1, the intelligent contract is represented as the intelligent contract of the designated address, the address of the intelligent contract is given in the parameter to, if the flag bit of the attach is 0 or no attach flag bit, the intelligent contract is represented as the intelligent contract of the designated address, and the address of the intelligent contract is automatically generated by the system.
Preferably, the intelligent contract requires a signature, and in the signature process, a corresponding private key is generated according to the unique transaction code, and the signature is generated through the private key to complete the transaction intelligent contract.
Preferably, the method for generating the intelligent contract address comprises the following steps: and calculating to obtain a corresponding hash value according to the address of the sender of the transaction user and the transaction number of the current transaction, and then finding a corresponding intelligent contract transaction address.
Preferably, the transaction address is a 160-bit address preset by the user.
Preferably, the transaction number is a natural number, starting from 0, the connection is incremented.
Preferably, the intelligent contract needs to be encrypted by using a symmetric encryption algorithm.
Compared with the prior art, the invention provides a method for specifying an address when an Ethernet workshop issues an intelligent contract, which has the following beneficial effects: the method for assigning the address when the ether house issues the intelligent contract can directly send out the transaction signed by the intelligent contract and directly manage the balance of the intelligent contract by assigning the issuing address in the intelligent contract.
The parts which are not involved in the device are the same as or can be realized by adopting the prior art, and the device has the advantages of simple structure and convenient operation.
