It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
Fig. 1 is a flowchart of a transaction broadcasting method according to an embodiment of the present invention. As shown in fig. 1, in this embodiment, the present invention provides a transaction broadcasting method suitable for blockchain nodes, where the blockchain network is configured with a corresponding transaction pool network, the transaction pool network includes a plurality of transaction pool nodes that communicate with each other, and each blockchain node is respectively registered with a push address for pushing a new transaction at any transaction pool node, where the method includes:
s12: receiving and storing a first transaction sent by a client, broadcasting a first transaction hash of the first transaction to other blockchain nodes, sending the first transaction to a first transaction pool node for broadcasting the first transaction to other transaction pool nodes, and pushing the first transaction to a plurality of blockchain nodes according to registered push addresses;
s14: receiving second transaction hashes broadcast by other blockchain nodes, and judging whether second transactions corresponding to the second transaction hashes exist locally: if not, monitoring whether a second transaction is received;
s16: and receiving and storing the third transaction pushed by the first transaction pool node.
Specifically, assume that there are 7 blockchain link points node 1-node 7 in the blockchain; a corresponding transaction pool network is configured in the block chain network, and 3 transaction pool nodes txpool 1-txpool x3 are arranged in the transaction pool network; a push address for pushing a new transaction is registered in txpool1 by node1, node2 and node3, a push address for pushing a new transaction is registered in txpool2 by node4 and node5, and a push address for pushing a new transaction is registered in txpool3 by node6 and node 7; suppose that tx1 to tx10 exist locally in node1 to node 7;
take node1 as an example to broadcast a hash (tx10) to node 2;
the node2 executes step S14, receives the hash (tx10), determines whether tx10 corresponding to the hash (tx10) exists locally, and broadcasts the hash to other blockchain nodes (tx10) because tx10 exists locally.
Taking the example that the client of the user A generates tx11 and establishes connection with the node 1;
the client of the user A generates tx11 and sends the tx11 to the node 1;
the node1 executes the step S12, receives and stores tx11 sent by the client of the user A, broadcasts the hash (tx11) to nodes 2 to 7, and sends tx11 to txpool 1; txpool1 broadcasts tx11 to txpool2 and txpool 3;
node2 executes step S16, receiving tx11 pushed by txpool 1;
node3 executes step S16, receiving tx11 pushed by txpool 1;
node4 executes step S16, receiving tx11 pushed by txpool 2;
node5 executes step S16, receiving tx11 pushed by txpool 2;
node6 executes step S16, receiving tx11 pushed by txpool 3;
node7 executes step S16, receiving tx11 pushed by txpool 3;
take the example that node2 receives the hash (tx11) broadcast by node1 before it receives tx11 pushed by txpool 1;
the node2 executes step S14, receives the hash (tx11), determines whether tx11 corresponding to the hash (tx11) exists locally, and monitors whether tx11 is received because tx11 does not exist locally.
The above embodiment assumes that there are 7 block link points node 1-node 7 in the block chain; a corresponding transaction pool network is configured in the block chain network, and 3 transaction pool nodes txpool 1-txpool x3 are arranged in the transaction pool network; a push address for pushing a new transaction is registered in txpool1 by node1, node2 and node3, a push address for pushing a new transaction is registered in txpool2 by node4 and node5, and a push address for pushing a new transaction is registered in txpool3 by node6 and node 7; suppose that tx1 to tx10 exist locally in node1 to node 7; taking an example that node1 broadcasts a hash (tx10) to node2, a client of user a generates tx11, the client of user a establishes a connection with node1, and node2 receives the hash (tx11) broadcast by node1 before receiving tx11 pushed by txpool1 as an example, an exemplary explanation is made. In more embodiments, the number of the block chain nodes in the block chain, the number of the transaction pool nodes in the transaction pool network, and the registration relationship between the block chain nodes and the transaction pool nodes may also be configured according to actual requirements, so that the same technical effect can be achieved.
In the prior art of block chains, assuming that nodes 1-7 are connected with each other, node2 receives tx11 at least 6 times, while in the present application, node2 receives tx11 only once and hash (tx11) at least 6 times, and the data amount of hash (tx11) is much smaller than tx11, so that the method of the present application reduces transaction redundancy and improves transmission efficiency.
Fig. 2 is a flowchart of step S16 in a preferred embodiment of the method shown in fig. 1. As shown in fig. 2, step S16 includes:
s161: receiving and storing a third transaction pushed by the first transaction pool node;
s162: judging whether a third transaction hash of a third transaction exists locally:
if yes, go to step S163: monitoring is stopped for receipt of a third transaction.
Specifically, assume that node2 receives the hash (tx11) broadcast by node1 before receiving tx11 pushed by txpool1, at which time node2 monitors whether tx11 is received;
node2 executes step S161, receiving and storing tx11 pushed by txpool 1;
the node2 executes step S162 to determine whether there is a hash locally (tx 11);
since the hash (tx11) is locally stored, node2 executes step S163 to stop monitoring whether tx11 is received.
In more embodiments, the step of S163 may be configured according to actual requirements, for example, configured as a first manner "storing the third transaction pushed by the first transaction pool node, stopping monitoring whether the third transaction is received, and deleting the third hash value of the third transaction", or configured as a second manner "storing the third transaction pushed by the first transaction pool node, stopping monitoring whether the third transaction is received, and deleting the third hash value of the third transaction when the third transaction is pulled to generate the block" (when configured as a second manner, the second transaction is correspondingly pulled to generate the block, and the second hash value of the second transaction also needs to be deleted), so that the same technical effect may be achieved.
Fig. 3 is a flowchart of step S14 in a preferred embodiment of the method shown in fig. 1. As shown in fig. 3, in a preferred embodiment, step S14 includes:
s141: receiving second transaction hashes broadcast by other blockchain nodes, and judging whether second transactions corresponding to the second transaction hashes exist locally:
otherwise, step S142 is executed: when a second transaction corresponding to the second transaction hash is not received within a preconfigured first time length, requesting the second transaction from the block link node which sends the second transaction hash; and the number of the first and second groups,
s143: and storing the second transaction when the block chain node sending the second transaction hash returns the second transaction.
In the existing blockchain technology, node1 cannot broadcast tx11 to connected node2 due to network congestion, and because of mutual broadcast transactions among blockchain nodes, node2 will eventually receive tx11 broadcast by other blockchain nodes, such as node 3; however, in the present application, since tx11 is not generated by the client to which node2 is connected, it is only possible to wait for tx11 to be pushed by txpool 1; if txpool1 cannot push tx11 to node2 due to network congestion, node2 may not receive tx 11; the above problem can be solved by steps S141 to S143 shown in fig. 3.
FIG. 4 is a flow chart of a preferred embodiment of the method shown in FIG. 3. As shown in fig. 4, in a preferred embodiment, the method further includes:
s144: the second transaction hash is deleted.
The above embodiments configure a mechanism to delete transaction hashes.
FIG. 5 is a flow chart of a preferred embodiment of the method shown in FIG. 4. As shown in fig. 5, in a preferred embodiment, the method further includes:
s17: when the transaction pushed by the first transaction pool node is not received within a preset second time length, sending second request information for registering and pushing a new transaction to a second transaction pool node;
s18: and sending second request information for canceling the registration and pushing of new transaction to the first transaction pool node, so that the first transaction pool node deletes the pushing address of the current node when receiving the second request information.
Specifically, the node2 executes step S17, and when the transaction pushed by the txpool1 is not received within a preconfigured second time length (e.g. 2min), sends first request information for registering to push a new transaction to the txpool 2;
after receiving the first request message, the txpool1 stores the push address of the node 2;
the node2 executes step S18, and sends second request information for canceling the registration push new transaction to txpool 1;
when txpool1 receives the second request message, the push address of node2 is deleted.
The above embodiments save unnecessary network overhead for block-linked nodes.
FIG. 6 is a flow chart of a preferred embodiment of the method shown in FIG. 5. As shown in fig. 6, in a preferred embodiment, the method further includes:
s19: and requesting a second transaction which is not received within the first time length from the second transaction pool node.
Specifically, the node2 performs step S19, (after successful registration with txpool 2) node2 queries for a transaction (e.g., hash (tx12)) that has received the transaction hash locally but has not been received for more than a first duration, requests the transaction corresponding to the hash (tx12) from txpool2, and stores tx12 and deletes the hash (tx12) when txpool2 returns tx 12.
Step S19 is a method of how to obtain a transaction hash that has been received but a corresponding transaction has not been received beyond a first duration when a block link point registers a push address for pushing a new transaction with a new transaction pool node; in further embodiments, S19 may be configured as a first way to "request tx12 from the block link point that sent the hash (tx12), and when tx12 is returned, to store tx12 and delete the hash (tx 12)", or configured as a second way to "generate request information including hash (tx12), hash (tx13) and hash (tx14) if there are multiple transactions (e.g., hash (tx13) and hash (tx14)) that have received the transaction hash but have not been received for a first duration, and send the request information to tx pool2, and if there are corresponding tx12, tx13 and tx14 in tx 2, generate first information including tx12, tx13 and tx14 and return the first information to node 2", which may achieve the same technical effect.
Preferably, the registration of the block link node with a push address for pushing a new transaction at any transaction pool node includes:
sending first request information for registering and pushing new transactions to a plurality of transaction pool nodes so that each transaction pool node receiving the first request information can store a pushing address;
counting data results of the transaction pool nodes receiving the first request information within a preset third time length; wherein the data result comprises at least one of: transaction missed sending total number, transaction re-sending total number and time stamp for receiving transaction;
selecting a first transaction pool node according to a selection rule of a pre-configured transaction pool node and each data result;
and shielding the transactions pushed by other transaction pool nodes except the first transaction pool node (in another embodiment, the current step may also be configured according to actual requirements, and second request information for canceling the registration and pushing of new transactions is sent to other transaction pool nodes except the first transaction pool node and sending the first request information, so that when the second request information is received, the push address of the current node is deleted).
The above embodiment enables the block link point to be connected with the optimal trading pool node to obtain the optimal trading push service.
