Detailed Description
The embodiments of the present invention will be described in further detail with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the embodiments of the invention and that no limitation of the invention is intended. It should be further noted that, for convenience of description, only some structures, not all structures, relating to the embodiments of the present invention are shown in the drawings.
Example one
Fig. 1 is a flowchart of a method for upgrading a blockchain system according to an embodiment of the present invention, where the method is executed by a node in the blockchain system, and may be executed by an apparatus for upgrading the blockchain system. The method specifically comprises the following steps:
s110, generating an upgrading request of the block chain system, and initiating a voting proposal transaction according to the upgrading request.
In an embodiment of the present invention, the upgrading of the blockchain system refers to an update or modification operation of any data configuring the operation of the blockchain system, such as inherent system parameters and system mechanisms in the blockchain system. Before upgrading the blockchain system, generating an upgrading request of the blockchain system according to the blockchain system upgrading object to be updated or modified. Correspondingly, the upgrade request at least includes the blockchain system upgrade object and the corresponding target upgrade data, so as to instruct the blockchain system to update or modify the blockchain system upgrade object into the target upgrade data.
Preferably, determining a system parameter to be upgraded and a target value of the system parameter, and generating an upgrade request comprising the system parameter and the target value; and/or the presence of a gas in the gas,
determining a system mechanism to be upgraded and a target algorithm to be adopted in the system mechanism, and generating an upgrade request comprising the system mechanism and the target algorithm.
In the embodiment of the present invention, the system parameter may be any parameter for configuring the operation of the blockchain system, and the system mechanism may be any mechanism for configuring the operation of the blockchain system. It can be understood that the local node can initiate a corresponding system upgrade request only when it has voting proposal rights for the upgrade object, or the upgrade request transmitted to the blockchain system can be responded. And when the system parameters to be upgraded and/or the system mechanism to be upgraded are determined, the local node can check the authority of the local node.
Preferably, the determining the system parameter to be upgraded and/or the system mechanism to be upgraded includes:
and selecting the system parameters to be upgraded and/or the system mechanism to be upgraded from the system parameters and/or the system mechanisms which have the authority of initiating the voting proposal of the local node, so that the block generation node determines whether the local node has the authority of initiating the voting proposal of the system parameters and/or the system mechanism to be upgraded in the upgrading request, and if not, shielding the voting proposal transaction.
In the embodiment of the invention, whether the node has the system parameter to be upgraded and/or the voting proposal authority initiated by the system mechanism can be determined according to various modes such as the economic capability, the equity interest, the hardware capability and the stability of the node, so as to ensure that the node can propose and implement an effective upgrade request. It can be understood that the authority for initiating voting proposal possessed by different nodes is different, and the authority for initiating voting proposal corresponding to the same node at different periods is also different, the authority relates to an object to be upgraded which can initiate upgrading of the blockchain system, and may be any data configuring operation of the blockchain system, such as inherent system parameters and system mechanisms in the blockchain system, for example, the system parameters and the system mechanisms.
Preferably, the system parameters include at least one of block-out time, block height and voting effectiveness ratio; and/or the system mechanism includes at least one of a consensus mechanism and an encryption mechanism.
It should be noted that the object to be upgraded for the blockchain system upgrade can be any data configuring the operation of the blockchain system, such as inherent system parameters and system mechanisms in the blockchain system, and is not limited to the objects to be upgraded listed in the above examples.
Specifically, for upgrading the system parameters, in this embodiment, first, the system parameters to be upgraded are selected from the system parameters having the authority to initiate the voting proposal in the local node, the system parameters to be upgraded and the target values of the system parameters to be upgraded are determined, and then, an upgrade request including the system parameters and the target values is generated according to the system parameters to be upgraded and the target values. The system parameter may be any parameter configuring the operation of the blockchain system, and may include at least one of a block-out time, a block height, and a vote validation ratio. The block output time refers to a block generation period, namely, the time for generating a new block is limited; the block height refers to the number of blocks on the block link main chain, and for a single block, the block height can represent the identification of the block; the voting effective proportion refers to the default voting proportion which can be passed by the system for the blockchain system upgrading request or the voting proportion which can be passed by the blockchain system upgrading request and is updated by the initiator of the blockchain system upgrading request. It can be understood that the higher the voting effective ratio, the better, it means that there are more nodes in the blockchain to agree on the upgrade of the blockchain system.
Specifically, for the upgrade of the system mechanism, in this embodiment, a system mechanism to be upgraded is first selected from the system mechanisms having the authority to initiate a voting proposal in the local node, the system mechanism to be upgraded and a target algorithm to be adopted in the system mechanism to be upgraded are determined, and then an upgrade request including the system mechanism and the target algorithm is generated according to the system mechanism to be upgraded and the target algorithm. The system mechanism may be any mechanism that configures the operation of the blockchain system, and may include at least one of a consensus mechanism and an encryption mechanism. The consensus mechanism is that special nodes in the block chain vote for verification and confirmation of the transaction, and when a certain number of nodes achieve consensus in a specified time, the whole block chain can be considered to achieve consensus; the encryption mechanism refers to a mechanism for encrypting data of a transaction transmitted or stored in a block chain.
In this embodiment, when the blockchain system is upgraded, only the system parameters or the system mechanism may be upgraded, but since a specific system mechanism and the system parameters have a certain correlation, the system parameters and the system mechanism may also be upgraded at the same time. And then, after an upgrade request containing the upgrade object and the corresponding target upgrade data is generated, initiating a voting proposal transaction according to the upgrade request. The voting effective block height and/or voting effective proportion threshold value related to the voting proposal transaction can be set or selected so as to definitely judge the execution condition of the voting proposal transaction and the voting result.
Illustratively, due to the update of the consensus mechanism, different consensus mechanisms also differ with respect to block chain system delay and data throughput, as well as with respect to transaction processing capabilities. Assume that the local node of this embodiment intends to adopt a released Proof of trust (DPOS) to update the originally configured workload Proof mechanism (POW) in the blockchain system. Correspondingly, the POW mechanism is used as a system mechanism to be upgraded, and the DPOS mechanism is used as a target algorithm to be adopted in the system mechanism to be upgraded. Therefore, an upgrade request for upgrading the POW mechanism into the DPOS mechanism is generated, and voting proposal transaction is initiated according to the upgrade request.
S120, transmitting the voting proposal transaction in the block chain system, so that the block generating node performs the following operations: and voting in response to the voting proposal transaction, and responding to the upgrading request to upgrade the block chain system if the voting passes.
In an embodiment of the present invention, when the initiator of the upgrade request initiates a voting proposal transaction, the voting proposal transaction is transmitted to the blockchain system, so that most nodes or specific nodes in the blockchain and the current block generation node receive the voting proposal transaction. And the block generation node monitors all the affairs related to the voting proposal affairs in the block chain system, judges the block chain system environment, the initiator of the upgrading request and the content related to the upgrading request according to the voting proposal affairs, and determines whether to respond to the voting proposal affairs according to the judgment result. For example, the determination may be made according to the data information specified by the voting proposal transaction, such as the block height, the initiating authority of the initiator for the content associated with the upgrade request, and the like. If the voting proposal transaction can be voted, most nodes or specific nodes in the block chain vote for the voting proposal transaction. And the block generation node responds to the upgrading request to upgrade the block chain system according to the voting result if the voting passes, namely, an upgrading object associated with the upgrading request is updated or modified into target data, so that the block chain system is upgraded.
According to the technical scheme of the embodiment, an upgrade request is generated by a node in a block chain system aiming at a specific block chain system upgrade object, a corresponding voting proposal transaction is initiated according to the upgrade request, and the voting proposal transaction is propagated in a block chain network, so that a current block generation node in the block chain system responds to the voting proposal transaction, the voting result in the block chain system is supervised, and the block chain system is controlled to be upgraded according to the upgrade request when votes pass. The block chain system responds to the internal node to vote according to the voting proposal transaction initiated by the system upgrading request, and the corresponding upgrading is carried out on the block chain system after the voting proposal transaction associated with the upgrading request passes through the voting, so that the problem that the block chain system cannot be upgraded is solved, and the performance of the block chain system is improved.
Example two
On the basis of the first embodiment, this embodiment provides a preferred implementation of the method for upgrading a blockchain system, and can initiate a voting proposal transaction according to an upgrade request. In the embodiment of the invention, after the upgrade request containing the upgrade object and the corresponding target upgrade data is generated, the voting proposal transaction is initiated according to the upgrade request. The voting effective block height and/or voting effective proportion threshold value related to the voting proposal transaction can be set or selected so as to definitely judge the execution condition of the voting proposal transaction and the voting result. In the embodiment, when the block generation node receives the voting proposal transaction, the voting is directly carried out by judging the voting transaction; alternatively, the time node at which the voting starts may be limited. When the voting is finished, the voting result can be judged according to a default voting effective proportion threshold value of the block chain system or according to a voting effective proportion threshold value set by an initiator of the upgrading request.
Fig. 2 is a flowchart of initiating a voting proposal transaction according to a second embodiment of the present invention, and as shown in fig. 2, the method includes the following specific steps:
s210, determining the height of the voting effective block.
In a specific embodiment of the present invention, the time node at which the voting starts may be limited. Since the current block-out time in the blockchain system is fixed when the blockchain system is not upgraded, the voting validation block height can be set, that is, the start execution time node of the voting operation is determined. For example, the voting validation block height is determined to be 469739.
S220, initiating a voting proposal transaction according to the upgrading request and the height of the voting validation block, and responding to the voting proposal transaction to vote if the block generating node detects that the height of the current block to be generated is the height of the voting validation block.
In the embodiment of the invention, when an upgrade request including an upgrade object and target data thereof and the height of a voting validation block for starting voting are determined, a voting proposal transaction is initiated according to the upgrade request and the height of the voting validation block. The voting proposal transaction is used for indicating the block generation node to detect the height of the current block, responding to the voting proposal transaction if the height of the current block to be generated is detected to be the height of the voting effective block, and indicating a majority node or a special node in the block chain to vote for the voting proposal transaction associated with the upgrading request.
Illustratively, in the above example, the vote validation tile height is 469739. A voting proposal transaction containing a voting validation block height of 469739 is initiated according to the upgrade request and the voting validation block height, so that the block generation node detects whether the current block height to be generated is 469739, and when it is determined that a block with a block height of 469739 is generated, the block chain system is controlled to start voting and obtain a voting result. And finally, judging the voting result according to a default voting effective proportion threshold value of the system, and if the voting passing proportion value is greater than the default voting effective proportion threshold value of the system, determining that the voting passes and upgrading the block chain system.
In addition to the above embodiments, when a voting proposal transaction is initiated according to an upgrade request, the embodiment may also directly perform voting by judging the voting transaction, without limiting the start voting time node. Fig. 3 is a flowchart of initiating a voting proposal transaction according to a second embodiment of the present invention, and as shown in fig. 3, the method includes the following specific steps:
s310, determining a voting effective proportion threshold of the voting proposal transaction.
In the embodiment of the present invention, a default voting effective ratio threshold exists in the blockchain system, and in addition, the initiator may set the voting effective ratio threshold. For example, the native node may set the vote validation percentage threshold to 80%. The voting effective proportion threshold reflects the ratio of the number of nodes accepting the upgrade request to the number of all nodes voting, and it can be understood that the higher the voting effective proportion is, the better the voting effective proportion is, the more nodes in the block chain accept the upgrade of the block chain system at this time.
Preferably, a voting effective proportion threshold value set by the local node is obtained; if the set voting effective proportion threshold is equal to or smaller than the system voting effective proportion threshold, taking the system voting effective proportion threshold as the voting effective proportion threshold of the voting proposal transaction; otherwise, the set voting effective proportion threshold is used as the voting effective proportion threshold of the voting proposal transaction.
In the specific embodiment of the present invention, when the initiator sets the voting validation ratio threshold, one of the voting validation ratio thresholds set by the local node and the system default voting validation ratio threshold with a larger threshold is selected to be determined as the voting validation ratio threshold of the voting proposal transaction.
For example, in the above example, assuming that the default voting effective proportion threshold of the system is 60%, the voting effective proportion threshold set by the local node may be determined to be the voting effective proportion threshold of the voting proposal transaction, that is, 80%, by comparing with 80% of the voting effective proportion threshold set by the local node.
S320, initiating a voting proposal transaction according to the upgrading request and the voting effective proportion threshold value, and determining that the votes pass if the proportion value of the block generation nodes passing the votes is larger than the voting effective proportion threshold value.
In the specific embodiment of the invention, when the upgrading request containing the upgrading object and the target data thereof and the voting effective proportion threshold of the voting proposal transaction are determined, the voting proposal transaction is initiated according to the upgrading request and the voting effective proportion threshold of the voting proposal transaction. The voting proposal transaction is used for instructing the block generation node to control the block chain system to vote for the voting proposal transaction associated with the upgrading request and obtain a voting result. And finally, judging the voting result according to the determined voting effective proportion threshold, and if the voting passing proportion value is greater than the voting effective proportion threshold, determining that the voting passes and upgrading the block chain system.
Illustratively, in the above example, the vote validation percentage threshold is 80%. And initiating a voting proposal transaction containing 80% of the voting effective proportion threshold value according to the upgrading request and the voting effective proportion threshold value so as to enable the block generation node to control the block chain system to start voting and acquire a voting result. And finally, judging the voting result according to an 80% voting effective proportion threshold, and if the voting passing proportion value is greater than 80%, determining that the voting passes and upgrading the block chain system.
The foregoing embodiments may be executed in combination, and fig. 4 is a flowchart of initiating a voting proposal transaction according to a second embodiment of the present invention, as shown in fig. 4, the method includes the following specific steps:
and S410, determining the height of the voting validation block.
And S420, determining a voting effective proportion threshold of the voting proposal transaction.
S430, initiating a voting proposal transaction according to the upgrading request, the height of the voting validation block and the voting validation ratio threshold, enabling the block generating node to respond to the voting proposal transaction for voting if the current block height to be generated is the height of the voting validation block, and determining that the vote passes if the proportion value of the vote passing is greater than the voting validation proportion threshold.
In the embodiment of the invention, the time node of the start of voting and the threshold of the voting effective proportion can be set simultaneously, so that the starting condition and the ending condition of the voting process in the block chain system are judged, and the self-definition of the voting proposal transaction by the local node is completely realized.
According to the technical scheme of the embodiment, the voting proposal transaction associated with the upgrading request is finally generated by setting the height of the voting validation block associated with the voting proposal transaction and/or the voting validation ratio threshold. The self-definition of the local node on the voting proposal transaction is realized, the block chain system is convenient to upgrade according to the user requirements, and the user experience and the performance of the block chain system are improved.
EXAMPLE III
Fig. 5 is a flowchart of a method for upgrading a blockchain system according to a third embodiment of the present invention, where the method is executed by a blockchain generation node in the blockchain system, and can be executed by a blockchain system upgrading apparatus. The method specifically comprises the following steps:
s510, voting is carried out in response to the voting proposal transaction provided by the initiator in the block chain system, and a voting result is obtained.
In an embodiment of the present invention, the voting proposal transaction is generated according to an upgrade request of the blockchain system generated by the initiator. After receiving the voting proposal transaction, the block generation node in this embodiment may directly respond to the voting proposal transaction provided by the initiator in the block chain system by determining the voting transaction, control the block chain system to vote according to the voting proposal transaction, and acquire a voting result.
The embodiment may also detect the block chain system at any moment according to the voting proposal transaction if it is determined that the voting start time node is limited in the voting proposal transaction, respond to the voting proposal transaction when the voting start time node that is set in the voting proposal transaction is detected, control the block chain system to vote according to the voting proposal transaction, and obtain a voting result.
Illustratively, according to the voting proposal transaction, if the voting effective block height is set in the voting proposal transaction, if the block generation node detects that the current block height to be generated is the voting effective block height included in the voting proposal transaction, the voting proposal transaction transmitted by the initiator is responded, the block chain system is controlled to vote according to the voting proposal transaction, and a voting result is obtained.
S520, if the voting is determined to pass according to the statistical voting result, controlling the block chain system to respond to the upgrading request to upgrade the block chain system.
In the embodiment of the present invention, after obtaining the voting result in the block chain, the block generation node may determine the voting result according to a default voting effective proportion threshold of the block chain system, and if the voting passing proportion value is greater than the default voting effective proportion threshold of the system, it is determined that the voting passes, and the block chain system may be updated.
The embodiment may also determine, according to the voting proposal transaction, the voting result according to the voting effectiveness ratio threshold of the voting proposal transaction if it is determined that the voting effectiveness ratio threshold is limited in the voting proposal transaction, and determine that the vote passes if the voting pass ratio value is greater than the voting effectiveness ratio threshold of the voting proposal transaction, so as to upgrade the block chain system.
In this embodiment, after determining that the vote for the upgrade request passes, the block generation node controls the block chain system to respond to the upgrade request, and updates or modifies the upgrade object associated with the upgrade request to the target data, thereby implementing the upgrade on the block chain system.
Preferably, the target value of the system parameter to be upgraded in the upgrade request is controlled to be the current value of the system parameter in the block chain system; and/or the presence of a gas in the gas,
and controlling a target algorithm of the system mechanism to be upgraded in the upgrade request in the blockchain system as a current algorithm adopted by the system mechanism.
In the embodiment of the present invention, the block generation node may use the target value of the system parameter to be upgraded in the block chain system as the current value of the system parameter according to the upgrade request, so as to upgrade the system parameter; and/or the block generation node can take the target algorithm of the system mechanism to be upgraded in the block chain system as the current algorithm adopted by the system mechanism according to the upgrading request, so as to realize the upgrading of the system mechanism.
It should be noted that, in response to the voting proposal transaction, the block generation node for controlling the block chain system to vote and the block generation node for obtaining the voting result and upgrading the block chain system according to the voting result may be the same block generation node. However, since the current block generation node in the blockchain system is continuously updated and changed, the two block generation nodes may also be different block generation nodes corresponding to different times. The change of the block generation node does not affect the normal execution of the scheme of the embodiment.
According to the technical scheme of the embodiment, the current block generation node responds to the voting proposal transaction provided by the initiator in the block chain system, controls the block chain system to vote for the upgrading request and obtains the voting result; and if the voting is determined to pass according to the statistical voting result, controlling the block chain system to respond to the upgrading request to upgrade the block chain system. The block generation node responds to the voting proposal transaction initiated by the internal node according to the system upgrading request, controls the block chain system to vote, and correspondingly upgrades the block chain system after the voting proposal transaction associated with the upgrading request passes through the voting, thereby solving the problem that the block system cannot be upgraded and improving the performance of the block chain system.
Example four

In the embodiment of the present invention, before voting in response to a voting proposal transaction provided by an initiator in a blockchain system, a blockchain generation node may determine whether a node has a system parameter to be upgraded and/or an initiating voting proposal authority of a system mechanism according to various ways such as economic capacity, equity interest, hardware capacity, stability, and the like of the initiator node, so as to ensure that the initiator node can propose and implement an effective upgrade request.
S620, voting is carried out in response to the voting proposal transaction provided by the initiator in the block chain system, and a voting result is obtained.
In an embodiment of the present invention, the voting proposal transaction is generated according to an upgrade request of the blockchain system generated by the initiator. After receiving the voting proposal transaction, the block generation node in this embodiment may directly respond to the voting proposal transaction provided by the initiator in the block chain system by determining the voting transaction if the initiator node has the system parameters to be upgraded and/or the voting proposal initiating authority of the system mechanism. Or, according to the voting proposal transaction, if the voting start time node in the voting proposal transaction is further judged to be limited, the block chain system is detected at all times, and when the voting start time node which is set in the voting proposal transaction is detected, the voting proposal transaction is responded.
Preferably, if it is detected that the current block height to be generated is the voting validation block height included in the voting proposal transaction, voting is performed in response to the voting proposal transaction transmitted by the initiator.
In the embodiment of the invention, by limiting the voting start time node, when the block generation node detects that the voting start time node is reached, the block chain system is controlled to vote according to the voting proposal transaction and acquire the voting result in response to the voting proposal transaction.
S630, if the proportion value of the votes passing is larger than the threshold value of the voting effective proportion, determining that the votes pass.
In an embodiment of the present invention, when the voting is finished or the voting time expires, the block generation node may determine the voting result according to a default voting effectiveness ratio threshold of the block chain system, or according to a voting effectiveness ratio threshold of the voting proposal transaction. The voting pass can be judged only if the proportion value of the voting pass is larger than the voting effective proportion threshold value.
Preferably, if the proportion value of the voting passes is greater than the voting effectiveness proportion threshold value included in the voting proposal transaction, the voting passes are determined.
In the specific embodiment of the present invention, the voting effective ratio threshold included in the proposal transaction may be a voting effective ratio threshold defaulted by the blockchain system, or may also be a voting effective ratio threshold set by the initiator of the upgrade request, and the two are selected as the voting effective ratio threshold of the voting proposal transaction. And similarly, the voting pass can be judged only if the proportion value of the voting pass is greater than the voting effective proportion threshold value included in the voting proposal transaction.
