Description
Technical Field
The present invention relates to the field of a block chain, and in particular, to a method and an apparatus for updating a rule of a block chain, a block chain node point, and a network.
Background
Since the advent of the bitcoin system in 2009, which brought many innovations in computer science and electronic cash, decentralized cryptocurrency, represented by bitcoin and its derived competitive coins, received a great deal of attention. The currency system is characterized in that a distributed shared general ledger is constructed based on a block chain, so that the safety, reliability and decentralization characteristics of system operation are guaranteed.
The block chain refers to a technical scheme for collectively maintaining a reliable database in a decentralized and distrust mode, and is a string of data blocks which are generated in a correlation mode by using a cryptography method. The technical scheme mainly enables any plurality of nodes participating in the system to generate data blocks through a string of data blocks which are associated by using a cryptography method, wherein each data block contains all information exchange data of the system within a certain time, and data fingerprints are generated for verifying the validity of the information and linking the next database block.
For the blockchain, how to prevent the ledger from being tampered, how to ensure the data consistency among the nodes is a problem to be solved when the blockchain establishes the decentralized transaction, and therefore a consensus mechanism is generated.
So far, there are the following mechanisms for block chain consensus: PoW workload certification, PoS stock right certification, DPoS authorization stock right certification.
The workload Proof mechanism (Proof of work) has the advantage of complete decentralization, in a block chain which is commonly recognized by the workload Proof mechanism, nodes can freely enter and exit, the accounting right is contended by calculating the numerical value of the random hash, and the capability of obtaining the correct numerical value solution to generate a block is the concrete expression of the node computing power. Its advantages are high speed verification, high number of nodes, high cost and high self-observing performance. The disadvantages are that a large amount of algorithm and computing resources are consumed, and the period for reaching the consensus is long.
The Proof of rights mechanism (Proof of stamp) requires a prover to provide ownership of a certain amount of cryptocurrency. The equity accreditation mechanism operates in such a way that when a new block is created, the miners need to create a "minty" transaction that sends some coins to the miners themselves in a predetermined proportion. The equity certification mechanism proportionally reduces the ore digging difficulty of the nodes according to the proportion and time of tokens owned by each node and an algorithm, thereby accelerating the speed of searching random numbers. Its advantages are short time needed for agreeing, and saving energy. The disadvantage is that the nodes in the network are still essentially required to carry out the ore digging operation, and the account transfer authenticity is difficult to guarantee.
The authorized Proof of stock mechanism (freed Proof of stamp), similar to the voting of board of directors, has a built-in real-time shareholder voting system, just as the system is holding a never-scattered shareholder meeting at any time, where all the shareholders vote to decide corporate decisions.
The authorized equity proves that the negative effect brought by centralization can be counteracted by implementing scientific democratics while the traditional PoW mechanism and PoS mechanism problems are solved. The decentralized creation of block chains based on DPoS mechanisms relies on a certain number of representatives, not on the totality of users. In such a block chain, the whole nodes vote to select a certain number of representative nodes, and the representative nodes proxy the whole nodes to confirm the block and maintain the ordered operation of the system. At the same time, all nodes in the blockchain have the right to be struck and represented at any time. If necessary, all the nodes can make the existing node representatives lose the membership of representatives through voting, and the new representatives are reselected to realize real-time democratics. The authorization and equity certification mechanism can reduce the number of nodes participating in verification and accounting, thereby achieving second-level consensus verification.
In the operation process of the block chain network, sometimes the on-chain rules need to be updated, such as generating rules for updating tokens or handling fees of each block or the number of tokens of each block, and in this case, how to ensure the update of the rules is agreed by most nodes and how to ensure the fairness of the rules is a problem to be considered.

Detailed Description
The technical solutions 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 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 invention.
Before further detailed description of the present invention, terms and expressions referred to in the embodiments of the present invention will be described below.
Tokens, referred to in embodiments of the present invention as encrypted internet currency, are distributed digital currency based on cryptography, including bitcoin, ethercoin, ledebut coin, and other similar derivative currencies, where different blockchains may define different tokens.
The Block (Block) is a storage unit, each Block realizes the link (chain) through random hash (also called hash algorithm), the Block head (Block head) of the next Block contains the hash value of the previous Block, thereby realizing the sequential connection of the blocks and forming the Block chain.
The block chain (Blockchain) is characterized in that a plurality of nodes are related to each other by a string of nodes by using a cryptography method to generate a block, the block adopts a structure of a block head and a block body, data used for verifying the validity of recorded data in the block head and index data of a previous block are included in the block body, and the block body contains the recorded data within a certain time.
Functionally, a blockchain is a distributed database that is run by a group of distributed nodes and is used to store various records, such as records of virtual currency transactions. In terms of data structure, the blockchain includes a series of blocks, once a new block is added to the blockchain, the new block cannot be removed, and the blocks contain the recorded data for verifying the validity (anti-counterfeiting) of the recorded data and generating the next block.
Taking bitcoin as an example, the transaction of bitcoin depends on the confirmation of nodes in the running blockchain, when the bitcoin transaction is confirmed by a node for the first time, the corresponding transaction list is added to the latest block in the blockchain, the transaction is continuously confirmed by other nodes in the blockchain network to avoid transaction repetition, when the confirmation is obtained in enough blocks (namely, the transaction is recorded in blocks), the transaction is finally confirmed, and the transaction is not reversible.
Asymmetric encryption is a secret method of a key. Asymmetric encryption algorithms require two keys: public key (publickey) and private key (privatekey). The public key is paired with the private key, and if data is encrypted with the private key, it can only be decrypted with the corresponding public key. This algorithm is called asymmetric encryption algorithm because two different keys are used for encryption and decryption. The basic process of realizing confidential information exchange by the asymmetric encryption algorithm is as follows: the first party generates a pair of keys and discloses one of the keys as a public key to the other party; the party B obtaining the public key encrypts the confidential information by using the key and then sends the encrypted confidential information to the party A; the first party decrypts the encrypted information by using another private key stored by the first party.
Referring to fig. 1, an embodiment of the present invention provides a method for updating a rule of a block chain, including:
s101, when receiving the initiated rule updating request, obtaining the type of the current node.
In the present embodiment, each node located in the blockchain network is connected through the P2P network. In this embodiment, the nodes include two types, a representative node and a common node, and the representative node can be generated by voting by all nodes. The voting may be performed according to the contribution of each node to the whole block chain or the integral of each node, and the present invention is not limited in particular. In addition, the whole nodes can also replace the representative nodes or make a representative node lose the qualification by voting.
In this embodiment, the rule update request may be, for example, the token acquisition amount, the difficulty or the transaction fee of updating the blockchain network, the election mode of replacing the representative node, and the like, which are determined according to the nature of the blockchain network, and the present invention is not limited thereto.
And S102, sending the rule updating request to a preset node according to the type of the node.
S103, obtaining feedback of the node receiving the rule updating request to the rule updating request, and judging whether the feedback meets a preset requirement.
And S104, when the feedback meets the preset requirement, submitting the rule updating request to all nodes of the block chain network so as to acquire the approval rate of all nodes to the rule updating request.
In this embodiment, if the type of the node initiating the rule update request is a representative node, the rule update request is sent to other representative nodes, and the other representative nodes determine whether it is necessary to perform the rule update. When the ratio of the number of the representative nodes agreeing to the rule updating request to the number of all the representative nodes is larger than a first preset ratio, the rule updating request is agreed by the representative nodes, at this time, the rule updating request is sent to all the nodes in the block chain network, and the rule updating request is voted by all the nodes.
In this embodiment, if the type of the node initiating the rule update request is a common node, the rule update request is sent to the global node, and if the number of nodes agreeing to the rule update request reaches a second preset proportion of the global node, the rule update request is submitted to the global representative node, and then the representative node submits the rule update request to the global node for voting.
In this embodiment, the first preset ratio may be set to 4/5, and the second preset ratio may be set to 1/10, but it should be noted that, in other embodiments of the present invention, the first preset ratio and the second preset ratio may be set according to actual needs, and the present invention is not limited herein.
And S105, when the approval rate is greater than a preset threshold value, updating a rule to the block chain, and starting trial run timing.
And S106, after the preset time is reached, voting is carried out according to the contribution value integral of the node in the trial operation period, and whether the updated rule is effective or not is determined according to the contribution value integral of the voting.
In this embodiment, after the rule update request is sent to the global node, if the approval rate for the rule update request is greater than a preset threshold (e.g., 2/3), it indicates that the rule has been approved by most people, and a commissioning may be initiated. At this time, a timer is started to count down (for example, set to count down for 60 days), and the contribution integral of each node to the blockchain network during the count-down period is obtained. The contribution score may be determined by the demo link network during the development design, for example, by determining the number of blocks, and the invention is not limited thereto.
In this embodiment, after the countdown is finished, a vote is again performed, at this time, the contribution value integral sum of the approved nodes is obtained, and when the ratio of the contribution value integral sum to the total contribution value integral is greater than 2/3, the updated rule is determined to be valid, otherwise, the updated rule is determined not to be valid. Because the contribution value integral represents the contribution degree of the node to the whole block chain, the method can ensure that the updating result of the rule is the selection made by the node which has more sufficient knowledge on the rule, and ensure the relative objectivity of the result.
In summary, the rule updating method for the blockchain provided by this embodiment may provide the rule updating request regardless of the representative node or the common node, and the execution and validation of the final rule need to depend on the confirmation of all nodes and the feedback of the node that finally contributes to the blockchain network, so as to maximally consider the fairness and efficiency of the rule updating of the whole blockchain network.

the representative node is further configured to obtain feedback of the representative node receiving the rule update request on the rule update request, and submit the rule update request to all nodes of the blockchain network when the feedback meets a preset requirement, so as to obtain an approval rate of all nodes on the rule update request; when the approval rate is greater than a preset threshold value, the block chain network updates the rule to the block chain, starts trial operation timing, and votes according to the contribution value integral of the node in the trial operation period after the timing reaches the preset time, so as to determine whether the updated rule is effective according to the voted contribution value integral;
the common node is used for initiating a rule updating request and sending the rule updating request to all nodes;
the common node is further configured to obtain feedback of the node receiving the rule update request on the rule update request, and when the feedback meets a preset requirement, submit the rule update request to a representative node, so that the representative node sends the rule update request to all nodes of the block link network to obtain an approval rate of all nodes on the rule update request; when the approval rate is greater than a preset threshold value, the block chain network updates the rule to the block chain, starts trial operation timing, and votes according to the contribution value integral of the node in the trial operation period after the timing reaches the preset time, so as to determine whether the updated rule is effective according to the voted contribution value integral.
