Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, 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.
It is to be understood that the use of a plurality of references in the present invention refers to two or more, and the terms "first", "second", etc. in the description of the present invention are used for descriptive purposes only and are not to be construed as indicating or implying relative importance, nor is it to be construed as indicating or implying any order.
Example 1:
fig. 1 is a schematic diagram of a data archiving process of a block chain according to an embodiment of the present invention, where the process includes:
s101: a write request for transaction data is received.
S102: and detecting whether the first block chain meets a preset filing condition, if not, performing S103, and if so, returning to S104.
The data archiving method for the block chain provided by the embodiment of the invention is applied to any block chain node of the block chain, and the block chain node can be electronic equipment such as a PC (personal computer), a server cluster and the like with operation and storage functions.
In the present embodiment, the first blockchain may also be referred to as a current blockchain, which refers to a blockchain that is not archived, and only one current blockchain exists in the blockchain link points. The archive blockchain refers to a blockchain that has satisfied a predetermined archive condition and is prohibited from data writing, wherein after the current blockchain satisfies the predetermined archive condition, the current blockchain is prohibited from data writing, and after a new blockchain is created at a block link point, the current blockchain becomes a archive blockchain, and the new blockchain at the block link point becomes a new current blockchain, wherein after the current blockchain and the first blockchain satisfy the predetermined archive condition, the newly created block chain at the block link point may also be referred to as a second blockchain in the embodiment of the present invention.
In addition, it should be understood that the block chains referred to in the embodiments of the present invention, such as the first block chain, the second block chain, the current block chain, etc., refer to a block chain that can be used for storing transaction data, i.e., a block chain composed of blocks storing transaction data one by one, rather than a block chain technique or a block chain system, etc.
In addition, the preset filing conditions in the embodiment of the present invention include: the block height of the block chain reaches one or more of a set block height threshold value, the storage space occupied by the block chain is larger than a set storage space threshold value, the creation time length of the block chain is larger than a set time length threshold value and the like.
Specifically, after receiving a write request of transaction data each time, the block link point detects whether the first block link point meets a preset archive condition, and if the first block link point meets any preset archive condition, for example: and determining that the first block chain meets a preset filing condition when the block height of the first block chain reaches a set block height threshold.
S103: writing the transaction data to the first blockchain.
S104: and newly building a second block chain, and writing the transaction data into the second block chain, wherein the created block of the second block chain points to the first block chain.
Specifically, if the first blockchain does not meet the preset archiving condition, it is indicated that the first blockchain still meets the storage condition of the transaction data, and the blockchain node writes the transaction data into the first blockchain; if the first block meets the preset filing condition, it indicates that the first block chain does not meet the storage condition of the transaction data, the block link point prohibits the data writing function of the first block chain, prevents the newly generated transaction data from being written into the first block chain, and prevents the transaction data on the first block chain from being tampered, and at the same time, the block link point newly creates a second block chain, and points the created block of the newly created second block chain to the first block chain, for example: by writing the identification information of the first block chain into the block header of the created block of the second block, the created block of the newly-created second block chain is pointed to the first block chain, and preferably, the hash value of the created block of the second block chain pointing to the first block chain is the hash value of the last block of the first block chain in the created block of the second block chain.
And the block link point writes the transaction data into the second block chain after the created block of the newly-built second block chain points to the first block chain, and the newly-built second block chain is used for the subsequent newly-generated transaction data before the preset filing condition is not met, namely the block link point writes the transaction data after receiving the writing request of the subsequent transaction data.
Because the newly generated block chain in the block chain link points to the last block chain generated by the block chain link point, when the new block chain link point is added, the newly added block chain link point can determine all transaction data needing to be synchronized according to the directional relation between the block chains in any block chain link point of the existing block chain, so that the synchronization efficiency is improved, and the synchronization accuracy is ensured.
In addition, in the embodiment of the present invention, when the second block chain is newly created at the block link point, the second block chain may be newly created in the same storage device as the storage device corresponding to the address of the first block chain at the block link point, or the second block chain may be newly created in a storage device different from the storage device corresponding to the address of the first block chain. Preferably, when the second blockchain is newly created, the blockchain node may determine whether the size of the remaining storage space of the storage device corresponding to the address of the first blockchain is greater than a set storage space threshold, if so, create the second blockchain in the storage device corresponding to the address of the first blockchain, and if not, create the second blockchain in other storage devices whose size of the remaining storage space in the blockchain node is greater than the set storage space threshold.
Since the block link point creates the second block chain after receiving the write request of the transaction data and detecting that the first block chain meets the preset archive condition in the embodiment of the invention, wherein the created block of the second block chain points to the first block chain and is used for writing transaction data, because the address of the first block chain does not need to be changed when the second block chain is created, the address of the created second block chain is not limited by the address of the first block, the block link point can create the second block chain in the same or different storage devices corresponding to the address of the first block chain in the block link point, used for storing new transaction data, avoids the problem that the block chain link points meet the storage bottleneck, realizes the infinite capacity expansion of the block chain, and the data archiving method does not relate to the transfer of the transaction data, avoids the transaction data from being tampered after the transfer, and improves the practicability of the data archiving of the block chain.

and aiming at the transaction data, adding the identification information of the transaction data, the identification information of the target block chain corresponding to the transaction data and the index relation of the identification information of the target block chain in an index table.
In the embodiment of the present invention, the identification information of the transaction data may be identification number (ID) information of the transaction data, or may also be information of a key field in the transaction data, and the like, the identification information of the block may be height information of the block on the blockchain, and the identification information of the blockchain may be information of a digital fingerprint of the blockchain, information of a storage address, ID information of the blockchain, and the like. In the embodiment of the invention, after the transaction data is written into the block chain, the index relationship between the transaction data and the block chain and between blocks of the block chain is determined, and the index relationship is added into the index table to maintain the index table.
As shown in fig. 2, when transaction data is queried, a block link node receives a query request containing transaction data identification information sent by a user, and queries whether the transaction data is located in a filing block chain and location information of the transaction data through the identification information of the transaction data and an index table, where the location information of the transaction data may be identification information of a block chain and identification information of a block corresponding to the transaction; if the transaction data are located in the filing blockchain, inquiring the transaction data on the filing blockchain according to the position information of the transaction data, and returning the inquired transaction data result; and if the transaction data is not located in the filing blockchain, inquiring the transaction data on the current blockchain, namely the unfiled blockchain, and returning the inquired result of the transaction data.
