Description
Technical Field
The invention relates to the technical field of block chains, in particular to a novel alliance chain with a light account book as a characteristic.
Background
Most of the existing alliance chains are reconstructed based on the hyper-bridge-fabric, and the account book is not innovated too much, or the account book design of the hyper-bridge-fabric is adopted, namely: the method comprises the steps that firstly, orderer nodes pack and drop transactions to form an account book, then lead peer nodes pull the account book, and finally the account book is synchronized among the peer nodes through a gossip protocol, so that the formed final state is that all the nodes store the same account book in full amount.
The accounts stored in each node are all full and the same, and cannot be applied to some special service scenarios, such as: the node is deployed on a small terminal device, a storage space enough for accommodating a full-volume ledger cannot be provided, and a client connected with the node does not care about transactions irrelevant to the node, namely the node does not need to synchronize the full-volume ledger but only synchronizes the transactions relevant to the node in the ledger. Aiming at the problems, a novel alliance chain which takes a light-weight account book as a characteristic is designed.
Disclosure of Invention
The invention aims to provide a novel alliance chain with a light-weight account book as a characteristic, which has the advantage of universality in the current business mode by expanding the existing alliance chain on an account book layer, and solves the problem that the existing alliance chain cannot be applied to small-sized terminal equipment.
In order to achieve the purpose, the invention adopts the following technical scheme: a novel alliance chain with a light-weight account book as a characteristic comprises a plurality of full-amount nodes and a plurality of light-weight nodes, wherein each light-weight node is connected with each full-amount node, the full-amount nodes are used for collecting all endorsed transactions to perform sequencing and block dropping and forming transaction data information, and the transaction data information is further processed by an agreement mechanism to generate the full-amount account book;
The lightweight node initiates request data of a synchronous account book to a full-scale node, wherein the request data comprises a transaction identification list, and the transaction identification list comprises transaction source member numbers and transaction related member numbers to distinguish transaction information; the full-volume node receives request data from a synchronous account book in the light-weight node, the full-volume node generates light-weight response account book data by adopting an association filtering mode according to a transaction identification list in the request data and the full-volume account book, the full-volume node returns the response account book data to the corresponding light-weight node, and the light-weight node analyzes transactions in a block according to the response account book data and updates the world state in sequence; the full-volume nodes and the light-weight nodes are divided according to different account book storage modes, the full-volume nodes record all transaction account book data, and the light-weight nodes record transaction data related to the nodes; the association filtering mode is that if the transaction contains any information in the transaction identification list, the transaction meets the requirement of the lightweight node; if the transaction does not contain any information in the transaction identification list, the transaction does not meet the requirements of the lightweight node.
Furthermore, the full-scale node and the light-weight node can perform transaction endorsement, transaction verification and world state updating.
Compared with the prior art, the invention has the following beneficial effects:
1. different from the situation that each peer node in the traditional alliance chain can only store a full account book, each peer node in the novel alliance chain can determine whether to store a light account book or a full account book according to configuration; compared with a full account book, the light account book occupies a smaller storage space, is quicker to establish a world state, and is more suitable for being applied to business scenes of small-sized terminal equipment such as mobile phones and pos machines in a alliance chain.
Drawings
The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and together with the description serve to explain the principles of the invention and not to limit the invention. In the attached fig. 1:
fig. 1 is a schematic structural diagram of a novel federation chain featuring a lightweight ledger according to the present invention.
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.
Referring to fig. 1, a novel federation chain featuring a lightweight ledger includes a plurality of full-volume nodes and a plurality of lightweight nodes, each of the lightweight nodes is connected to each of the full-volume nodes, the full-volume nodes are used for collecting all endorsed transactions to perform sorting and blocking, and forming transaction data information, and the transaction data information is further processed by an agreement consensus mechanism to generate a full-volume ledger;
the lightweight node initiates request data of a synchronous account book to a full-scale node, wherein the request data comprises a transaction identification list, and the transaction identification list comprises transaction source member numbers and transaction related member numbers to distinguish transaction information; the full-volume node receives request data from a synchronous account book in the light-weight node, the full-volume node generates light-weight response account book data by adopting an association filtering mode according to a transaction identification list in the request data and the full-volume account book, the full-volume node returns the response account book data to the corresponding light-weight node, and the light-weight node analyzes transactions in a block according to the response account book data and updates the world state in sequence.
The full-amount node and the light-weight node are divided according to different account book storage modes, the full-amount node records all transaction account book data, and the light-weight node records transaction data related to the node.
The association filtering mode is that if the transaction contains any information in the transaction identification list, the transaction meets the requirement of the lightweight node; if the transaction does not contain any information in the transaction identification list, the transaction does not meet the requirements of the lightweight node.
The full-scale nodes and the light-weight nodes can perform transaction endorsement, transaction verification and world state updating.
Conventional transaction endorsements are as follows;
a. after the client creates the transaction, it sends a request to the endorsement node selected by the client, that is, sends a PROPOSE message to the endorsement node set selected by the transaction.
B. The endorsement node simulates the transaction and then generates an endorsement signature.
C. The submitting client obtains the endorsement of the transaction and broadcasts through the ordering service (the former submitting node waits, when enough messages and signatures are obtained, the transaction is concluded to be endorsed, the transaction involves multiple rounds of interaction with the endorsement node, and if not, the submitting client abandons the transaction and retries the transaction later).
d. The ordering service delivers a message to all nodes that propagates the transaction.
The operation mode is as follows: and after collecting all endorsed transactions, the full-volume node performs sorting and block dropping, and writes the blocks into a local account book after the step of achieving consensus, namely the full-volume account book.
The lightweight node sends a request for synchronizing the ledger to the full-volume node, and the request parameter comprises a transaction identification list (information for distinguishing transactions by transaction source member numbers and transaction related member numbers).
After receiving the synchronous account book request from the light-weight node, the full-volume node analyzes a transaction identification list, and filters the transactions in the local full-volume account book one by one according to the transaction identification list, wherein the method is as follows: if the transaction contains any information in the transaction identification list, the transaction meets the requirement of the lightweight node; if the transaction does not contain any information in the transaction identification list, the transaction does not meet the requirements of the lightweight node.
The full-scale node repackages the satisfactory transactions into blocks (block header and block meta-information is unchanged, only block data content is changed), which are returned to the lightweight node as part of the request response.
And after receiving the response, the lightweight node analyzes the transactions in the block and then sequentially updates the world state.
The invention is not described in detail, but is well known to those skilled in the art.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
