Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail with reference to fig. 1 to 3, the described embodiments should not be construed as limiting the present invention, and all other embodiments obtained by a person of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein is for the purpose of describing embodiments of the invention only and is not intended to be limiting of the invention.

Before further detailed description of the embodiments of the present invention, terms and expressions mentioned in the embodiments of the present invention are explained, and the terms and expressions mentioned in the embodiments of the present invention are applied to the following explanations.

Fabric: an open source project in the super account book is mainly applied to an enterprise-level block chain.

Consensus nodes (Orders): or called a sort node, the consensus node simply receives the transactions from all channels from the network, then sorts the transactions in time order according to the channels, and finally sorts the transactions into blocks after constructing the blocks.

Block discharging: and the sequencing node sends the constructed block to a confirmation node (Committer), the confirmation node (Committer) checks the integrity, signature and repetition of the transaction, checks whether the transaction conforms to an Endorsement strategy, executes legal transaction in the block after checking that the version and the ledger in the read set are consistent, and updates the state of the ledger.

Transactions (transactions), equivalent to the computer term "Transaction", include calls to smart contracts to effect operations on data related to a target account in the ledger, including operations to add, check, change, modify data in the form of Key-Value pairs in the account, or add new accounts in the ledger, not simply transactions in the business context, which embodiments of the present invention follow in view of the convention that "transactions" are colloquially used in blockchain technology.

A Block (Block) recording a data structure of the ledger data updated by the exchange within a period of time, marked with a timestamp and a unique mark (e.g. a digital fingerprint) of a previous Block, and after the Block is subjected to consensus verification by nodes in the Block chain network, the Block is appended to the end of the Block chain to become a new Block.

A chain of blocks (Blockchain), a chain of data structures in which blocks are assembled in a sequentially contiguous manner, each block having a hash value of a previous block or a subset thereof referenced therein, to cryptographically secure the recorded transaction against tampering and forgery.

A blockchain network incorporates new blocks into a set of centerless nodes of the blockchain in a consensus manner.

The account book (Legger) is the sum of data recorded by taking an account as a dimension in a block chain network, and comprises the elements of the account book data, the state of the account book, the state certification of the account book, a block index and the like.

The ledger data, the actual block data storage, i.e. the record of a series of ordered and non-falsifiable transactions recorded in the block chain, may be expressed in the form of a file system, and the update of the data in the account/account is realized when an intelligent contract called in the transaction is executed.

The ledger state, also referred to as state data, i.e. the state of the ledger data, may be in the form of key-value pairs in the database terminal, where the real-time ledger state is used to represent the latest record of key-value pairs updated by the agreed-upon exchange and the historical ledger state is used to represent the historical record of key-value pairs.

Consensus (Consensus), a process in a blockchain network, is used to agree on the outcome of a transaction among the nodes involved, and the mechanisms for achieving Consensus include Proof of workload (PoW), Proof of rights and interests (PoS, Proof of approval, Proof of share authorization (DPoS), Proof of elapsed Time (PoET, Proof of elapsed Time), and so on.

Intelligent Contracts (Smart Contracts), also called chain codes (chaincodes), are deployed in the blockchain network, and trigger the execution of programs according to conditions, and are used for operating the ledger through query, addition and modification so as to realize query or update of the ledger.

Example 1

Example 2

The difference between this embodiment and embodiment 1 is that the method for performing block output according to the sequence of received transactions after completing block construction by processing transactions satisfying the block output condition with the common node receiving transactions without interruption includes the following steps:

s1, the consensus node receives the transaction continuously;

Example 3

The difference between this embodiment and embodiment 2 is that, in step S1, after the common node receives the transactions without interruption, the transactions are sorted according to the order of the received transactions.

Further, the constructing of the block for completing the transaction processing comprises calculating a block Hash of the block. The block Hash of the calculation block comprises a Merkle root, a block head Hash value and a block height of the calculation block.

Example 4

The difference between this embodiment and embodiment 1 is that the blockchain adopts Fabric architecture.

Example 5

An apparatus for improving block chaining-out efficiency, comprising:

a memory for storing executable instructions;

Example 6

As shown in fig. 1, the present embodiment is an existing block chaining block processing flow, which includes the following steps performed in sequence:

s01, the consensus node receives the transaction;

s02, the consensus node judges whether the transaction meets the block-out condition, if so, the step S03 is carried out; if the block-out condition is not met, the consensus node waits for the transaction to meet the block-out condition and then goes to step S03;

s03, processing the transaction by the consensus node, and turning to the step S04 after the block structure is completed;

s04, the consensus node blocks the block constructed in step S03, and then the step S02 is proceeded after receiving a new transaction.

In the Fabric architecture, the block-out condition has two conditions, one is that there are many transactions in the block and the size of the block reaches the size configured in the configuration file, and the other is that there are few transactions in the block and the size of the block does not reach the size configured, then the consensus node waits until the size is large enough or the time configured in the configuration file is exceeded. With the above steps, it can be seen that if a block cannot meet the block output condition, the consensus node is stuck at the node, and subsequent transactions can only be queued for processing, without exerting the advantages of the multi-core computer, resulting in system resources being in an idle state, and overall efficiency is not high.

Example 7

As shown in fig. 2 and fig. 3, in the embodiment of the method, the consensus node receives the transaction 1, the transaction 2, and the transaction 3 in sequence, the consensus node starts to process the transaction after sequencing the transaction 1, the transaction 2, and the transaction 3, at a time node a, the consensus node first determines whether the transaction 1 can be blocked, and determines that the transaction 1 does not satisfy the blocking condition, and the consensus node suspends the transaction 1; then, a time node b, a consensus node judges whether the transaction 2 can be blocked or not, and the judgment result is that the transaction 2 meets the blocking condition; then entering a time node c, simultaneously processing the construction of a Block2 of the transaction 2 and judging whether the transaction 3 can output blocks, and simultaneously judging whether the transaction 1 can output blocks, wherein the result is that the transaction 1 meets a Block output condition and the transaction 3 does not meet the Block output condition; at the next time node d, the consensus node simultaneously processes the Block1 structure of transaction 1, the Block2 structure is completed, whether the Block1 is blocked is judged, if so, the Block1 is not blocked, the Block2 is suspended, if not, whether the Block can be blocked for transaction 3 is judged, and if so, the Block condition for transaction 3 is met; in the node e, after the Block1 is constructed, Block outputting is carried out, and after the Block1 is subjected to Block outputting; at node f, Block2 is out, Block3 is constructed, whether Block2 is out is judged, and the result is that Block2 is out; at node g, Block3 goes out.

Example 8

This embodiment is a comparison between embodiment 6 and embodiment 7, and includes 3 transactions to be sent to the consensus node, which are transaction a, transaction B, and transaction C, respectively, in this order, the time of the consensus node according to the transaction building block is 1min, the time of the consensus node waiting for transaction a to satisfy the block-out condition after receiving transaction a is 3min, the time of the consensus node waiting for transaction B to satisfy the block-out condition after receiving transaction B is 0.5min, and the time of the consensus node waiting for transaction B to satisfy the block-out condition after receiving transaction B is 3.5 min.

By adopting the method of embodiment 7, after receiving transaction a, the consensus node determines that a block cannot be immediately found, suspends transaction a to receive transaction B, determines that transaction B cannot be immediately found, suspends transaction B to receive transaction C, almost no time is consumed, after 0.5min, transaction B satisfies a block finding condition, the consensus node constructs a block according to transaction B with a block time of 1min, i.e., 1.5min, transaction B can find a block, since transaction a has not found a block, block B matching transaction B is suspended, and after 1.5min, transaction a satisfies a block finding condition, the consensus node constructs a block according to transaction a with a block time of 1min, and transaction C also satisfies a block finding condition, when the consensus node can construct only one block at a time, transaction C waits for the block corresponding to transaction a to be constructed and then constructs a block, block a corresponding to transaction a can be found, block B can be found after block a is found, thus transaction A is issued at minute 4, transaction B is issued at minute 4, and transaction C is issued at minute 5; when the consensus node can build at least 2 tiles at a time, transaction C starts building tiles at 3.5 minutes, so transaction A gets tiles at 4 minutes, transaction B gets tiles at 4 minutes, and transaction C gets tiles at 4.5 minutes. It can be seen that, although embodiment 7 adopting the scheme has no advantage over embodiment 6 in terms of the block output efficiency of the first block, when the transaction request is frequent, the block output efficiency of the subsequent transaction is greatly improved.

Example 9

The embodiment of the method for sequencing the receiving sequence of the transactions and sequencing the blocks of the transactions by the consensus node, which is used for receiving a new transaction at the consensus node, recording the parameters of the last transaction of the new transaction in the new transaction, updating the block record by the consensus node each time the block is generated, recording the transaction information of the last block of the new transaction, after the block corresponding to the new transaction is constructed, judging whether the information of the last transaction of the new transaction record is consistent with the transaction information of the last block of the consensus node, if so, generating the block, otherwise, waiting for the consensus node to complete the block generation, and then performing judgment again until the information of the last transaction of the new transaction record is consistent with the transaction information of the last block of the consensus node, and completing the block generation of the block corresponding to the new transaction.

Example 10

The embodiment provides another method for ordering transaction receiving sequence and sorting out blocks by a consensus node, wherein a data table is established in the consensus node, the data table records received transactions in sequence, the consensus node updates the data table when each block is issued, marks the transaction corresponding to the block, reads the next transaction information corresponding to the block after each block issuing or after a new block is established, and traverses the established block until a block matched with the transaction information corresponding to the block appears in the established block, and then the block is issued.
