Accelerating transaction deliveries in blockchain networks using acceleration nodes

1. A computer-implemented method, comprising:

selecting an acceleration node in a blockchain for sending a transaction from a first node to a second node based on determining that a transaction delivery time using the acceleration node is expected to be faster than a transaction delivery time that is expected by sending the transaction directly to the second node;

receiving, by the second node and from the acceleration node and using a blockchain transaction acceleration system, the transaction generated by the first node, wherein the transaction is sent from the first node to the acceleration node instead of being sent directly to the second node that is an intended recipient of the transaction, and wherein the first node, the second node, and the acceleration node are different nodes; and

executing, by the second node, the transaction.

2. The computer-implemented method of claim 1 , wherein the transaction is sent from the acceleration node to a recipient-side acceleration node, and wherein the computer-implemented method comprises:

receiving, by the second node, the transaction from the recipient-side acceleration node.

3. The computer-implemented method of claim 2 , wherein the acceleration node forwards transactions to one or more specific acceleration nodes in different networks.

4. The computer-implemented method of claim 1 , wherein the first node and the second node are in different networks.

5. The computer-implemented method of claim 1 , wherein the first node sends a copy of the transaction directly to the second node.

6. The computer-implemented method of claim 1 , wherein the blockchain transaction acceleration system is implemented in one or more nodes in the blockchain or in a server accessible by the blockchain.

7. A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations comprising:

selecting an acceleration node in a blockchain for sending a transaction from a first node to a second node based on determining that a transaction delivery time using the acceleration node is expected to be faster than a transaction delivery time that is expected by sending the transaction directly to the second node;

receiving, by the second node and from the acceleration node and using a blockchain transaction acceleration system, the transaction generated by the first node, wherein the transaction is sent from the first node to the acceleration node instead of being sent directly to the second node that is an intended recipient of the transaction, and wherein the first node, the second node, and the acceleration node are different nodes; and

executing, by the second node, the transaction.

8. The non-transitory, computer-readable medium of claim 7 , wherein the transaction is sent from the acceleration node to a recipient-side acceleration node, and wherein the operations comprise:

receiving, by the second node, the transaction from the recipient-side acceleration node.

9. The non-transitory, computer-readable medium of claim 8 , wherein the acceleration node forwards transactions to one or more specific acceleration nodes in different networks.

10. The non-transitory, computer-readable medium of claim 7 , wherein the first node and the second node are in different networks.

11. The non-transitory, computer-readable medium of claim 7 , wherein the first node sends a copy of the transaction directly to the second node.

12. The non-transitory, computer-readable medium of claim 7 , wherein the blockchain transaction acceleration system is implemented in one or more nodes in the blockchain or in a server accessible by the blockchain.

13. A computer-implemented system, comprising:

one or more computers; and

one or more computer memory devices interoperably coupled with the one or more computers and having tangible, non-transitory, machine-readable media storing one or more instructions that, when executed by the one or more computers, perform one or more operations comprising:

selecting an acceleration node in a blockchain for sending a transaction from a first node to a second node based on determining that a transaction delivery time using the acceleration node is expected to be faster than a transaction delivery time that is expected by sending the transaction directly to the second node;

receiving, by the second node and from the acceleration node and using a blockchain transaction acceleration system, the transaction generated by the first node, wherein the transaction is sent from the first node to the acceleration node instead of being sent directly to the second node that is an intended recipient of the transaction, and wherein the first node, the second node, and the acceleration node are different nodes; and

executing, by the second node, the transaction.

14. The computer-implemented system of claim 13 , wherein the transaction is sent from the acceleration node to a recipient-side acceleration node, and wherein the operations comprise:

receiving, by the second node, the transaction from the recipient-side acceleration node.

15. The computer-implemented system of claim 14 , wherein the acceleration node forwards transactions to one or more specific acceleration nodes in different networks.

16. The computer-implemented system of claim 13 , wherein the first node and the second node are in different networks.

17. The computer-implemented system of claim 13 , wherein the first node sends a copy of the transaction directly to the second node.

18. The computer-implemented system of claim 13 , wherein the blockchain transaction acceleration system is implemented in one or more nodes in the blockchain or in a server accessible by the blockchain.
