Description
Technical Field
The invention relates to the technical field of cryptography, in particular to a method for generating a block chain.
Background
The blockchain is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism and an encryption algorithm.
The Blockchain (Blockchain) is an important concept of the bitcoin, which is essentially a decentralized database, and is used as the underlying technology of the bitcoin, and is a series of data blocks which are generated by using a cryptographic method to be related, wherein each data block contains information of a batch of bitcoin network transactions, and the information is used for verifying the validity (anti-counterfeiting) of the information and generating the next block. The white paper English original edition of Bimingju does not have the word of blockchain actually, but rather has the chain of blocks. In the earliest translation version of the bitcoin white paper Chinese, chain of blocks is translated into a block chain. This is the earliest time of occurrence of the Chinese word "blockchain".
Trading over the internet almost always requires the processing of electronic payment information by means of third party credit agencies, and such systems are still inherently limited to "credit-based models", and the advent of the blockchain is solving this problem.
Disclosure of Invention
The technical problem to be solved by the present invention is to provide a method for generating a block chain to solve the problem that trades on the internet almost always require the help of a third-party credit institution to process electronic payment information, and such systems are still inherently limited to a "credit-based mode".
In order to solve the technical problems, the technical scheme of the invention is as follows: a method for generating block chain includes setting up a transaction accounting for multiple sub-nodes distributed at different places to complete together, each sub-node recording complete account to form legality of participating in supervision transaction and forming a general node for receiving request information of sub-node;
the asymmetric encryption and authorization technology is carried out on the general node, the transaction information stored on the block chain is disclosed, and under the condition of receiving the authorization of the request information of the subnodes, the authorization of the request information of the subnodes is verified, so that the related data can be accessed;
establishing a consensus mechanism for achieving consensus among all transaction bookings and confirming the validity of records so as to confirm the data and prevent tampering with the data to form data which cannot be tampered, so that the efficiency and the safety of the data are balanced;
finally, based on the data which can not be tampered, the predefined rule clauses can be automatically executed to form a block chain.
Transaction information in the blockchain is verified and stored using a blockchain data structure.
The data generation and updating of the sub-nodes are generated and updated by utilizing a distributed node consensus algorithm.
The creation of non-tamperproof data is cryptographically secured for data transmission and access.
The automated execution of predefined rule terms is a distributed infrastructure and computing mode in which data is programmed and manipulated by automated script code as an intelligent contract.
The one sub-node corresponds to one general node respectively so as to form one block, and thus, a plurality of sub-nodes form the general node corresponding to the sub-node so as to form a plurality of blocks.
The block includes transaction information, a hash formed from a previous block, and a random number.
The transaction information is task data carried by the block, and specifically comprises private keys of both transaction parties, transaction quantity and digital signatures of electronic money.
The hash formed by the previous block is used for connecting the blocks, so that the sequential arrangement of past transactions is realized.
The random number is the core of transaction achievement, all miner nodes compete for calculating the answer of the random number, the node which obtains the answer the fastest generates a new block, and the new block is broadcasted to all nodes for updating, and therefore a transaction is completed.
Compared with the prior art, the invention has the beneficial effects that:
the method for generating the block chain comprises the steps that a transaction accounting is jointly completed by a plurality of sub-nodes distributed in different places, and each sub-node records a complete account to form a legal transaction participating in supervision and can jointly make a certificate for the sub-nodes to form a total node for receiving request information of the sub-nodes; the asymmetric encryption and authorization technology is carried out on the general node, the transaction information stored on the block chain is disclosed, and under the condition of receiving the authorization of the request information of the subnodes, the authorization of the request information of the subnodes is verified, so that the related data can be accessed; establishing a consensus mechanism for achieving consensus among all transaction bookings and confirming the validity of records so as to confirm the data and prevent tampering with the data to form data which cannot be tampered, so that the efficiency and the safety of the data are balanced; finally, based on the data which can not be tampered, the predefined rule clauses can be automatically executed to form a block chain. The problem that trades on the Internet almost need to process electronic payment information by means of a third-party credit mechanism, and the system is still internally limited by a credit-based mode is solved.

Detailed Description
The following further describes embodiments of the present invention with reference to the drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Referring to fig. 1, a method for generating a block chain according to the present invention includes the following steps:
s101: establishing a transaction accounting for being completed by a plurality of sub-nodes distributed in different places together, wherein each sub-node records a complete account to form the legality of participating in supervision transaction and can make a certificate for the sub-nodes together to form a total node for receiving the request information of the sub-nodes;
s102: the asymmetric encryption and authorization technology is carried out on the general node, the transaction information stored on the block chain is disclosed, and under the condition of receiving the authorization of the request information of the subnodes, the authorization of the request information of the subnodes is verified, so that the related data can be accessed;
s103: establishing a consensus mechanism for achieving consensus among all transaction bookings and confirming the validity of records so as to confirm the data and prevent tampering with the data to form data which cannot be tampered, so that the efficiency and the safety of the data are balanced;
s104: finally, based on the data which can not be tampered, the predefined rule clauses can be automatically executed to form a block chain.
Transaction information in the blockchain is verified and stored using a blockchain data structure.
The data generation and updating of the sub-nodes are generated and updated by utilizing a distributed node consensus algorithm.
The creation of non-tamperproof data is cryptographically secured for data transmission and access.
The automated execution of predefined rule terms is a distributed infrastructure and computing mode in which data is programmed and manipulated by automated script code as an intelligent contract. Each miner is a node in a network of computers forming a whole to verify all bitcoin transactions. In each transaction, the algorithm rewards them with bitcoins, which have value in the real world, and the operators of these machines have the incentive to keep the machines running.
By utilizing the block chain, the block chain is compared with an open account book, records of all transactions are stored in the block chain, the block chain is maintained by miners, and the block chain is not exclusively controlled by an entity and is opened to all persons; various networks are created in parallel with bitcoin blockchains by which to accomplish tasks that bitcoin networks cannot accomplish, but blockchains can be utilized, such as to timestamp their jobs or to confirm jobs.
Such as counterty (which is a free open financial instrument platform in bitcoin networks), such as "sidechains", one of the common denominations of these networks, regardless of the form in which they are used to cover the overlap, is that they are tied to bitcoin blockchains, and the network effect they can obtain from is liquidity, without their crypto-currency as an auxiliary program, or as an alternative to blockchains as required by Ethereum.
Developing an open source, decentralized protocol, and built-in data, verification mode and transaction system, without any entity being able to control alone; this is where the traditional software industry began to break down, and the best examples are bitcoin, Ebay, Facebook and Uber are valuable because they would benefit greatly from the network effect that they would concentrate user data in their hands and benefit from transactions, and the decentralized protocol built over the blockchain would likely eliminate each individual component, for example, they could create a common decentralized data set, usable by anyone, and support bitcoin-based p2p transactions.
Indeed, for example, Lazooz, which is a real-time carpooling protocol, and the OpenBazaar protocol, which supports the free decentralized p2p market.
Generally, the problem of establishing an agreement is controversial, but the opportunity for them to easily determine whether the industry is well developed in the long term is considered to be an important component of the whole hierarchy. On these decentralized protocols, it is important for any developer to be able to quickly create new applications or experiments.
This can be a commercial service or an open source project, the best example of this trend is the API, and the open source node tool Toshi of Coinbase. The goals of the two are the same, but the API is a business service, whereas Toshi is open source. Most of the time, the applications built on this basis operate in the same way as our current approach, like Coinbase and PayPal, but a big difference for the user is that they are built on a decentralized protocol, each application can interface with other applications, like different email applications and bitcoin purses can interoperate.
It grows gradually from the bottom upwards, initially with miners, block chains and bitcoins, and something else is now created on this basis, which is established in this way.
This presents a series of interesting challenges for developers, creators and investors, as the value of the current internet's hierarchical structure is commercialized by the above blockchain hierarchy. But this architecture is best in that users benefit even more because web site conversion rates, transposition costs, individual ownership of data, and market dominance may decrease or no longer exist.
As shown in fig. 2, each of the sub-nodes corresponds to one of the total nodes, thereby forming one block, and thus, the plurality of sub-nodes form the total node corresponding thereto, thereby forming a plurality of blocks.
The block includes transaction information, a hash formed from a previous block, and a random number. The transaction information is task data carried by the block, and specifically comprises private keys of both transaction parties, transaction quantity and digital signatures of electronic money. The hash formed by the previous block is used for connecting the blocks, so that the sequential arrangement of past transactions is realized. The random number is the core of transaction achievement, all miner nodes compete for calculating the answer of the random number, the node which obtains the answer the fastest generates a new block, and the new block is broadcasted to all nodes for updating, and therefore a transaction is completed.
The block chain is relatively open, is commonly known, has transparent transaction, is anonymous to both sides and can not be tampered. Traceable anyone can participate in the blockchain network, each device can act as a node, and each node allows a complete copy of the database to be obtained. The nodes are based on a set of consensus mechanism, and the whole block chain is maintained together through competition calculation.
When any node fails, the rest nodes can still work normally. Meanwhile, the method is also used for removing the center and trust, a block chain is formed into an end-to-end network by a plurality of nodes, and no centralized equipment or management mechanism exists. The data exchange between the nodes is verified by a digital signature technology, mutual trust is not needed, and other nodes cannot be deceived as long as the data exchange is carried out according to the rules set by the system.
For example: when a wants to remit money to B, a new order entry is created detailing the transaction; this order item would then be sent to hundreds of other computers that own copies of the record, which confirm that the transaction is authorized and eventually they agree (or disagree) that all of the contents of the transaction are legitimate, and then give approval to the item as if a and B had hundreds of spectators standing around them, seeing that a handed over to B for money, and they all agree that a really handed over money to B, then what is the difference to the bank for transaction disclosure transparent? The benefit of this common record book (master node) is that it does not require banks, nor a centrally entitled company, and does not require trust in any financial institution, requires any intermediary, and is decentralized.
In detail, this shared logbook (total node) does not belong to any one individual or organization. It is owned by everyone that owns the notebook, but this does not mean that any person who owns the notebook can control it. In addition, this record is said to be "immutable" or colloquially, it is irreversible, as long as the internet is present, and every line will be permanent. If B wants to refund B's money, it will be a new item, returning the money instead of the original transaction of the transaction.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, and the scope of protection is still within the scope of the invention.
