US10592979

1. A method, comprising: (1) (6)

changing, via a node of a blockchain system, a status of a current blockchain of the blockchain system to a closed status and a retired status based on expiration of a limited time window defined in a smart contract implemented on the current blockchain;

creating, via the node, a genesis block associated with a new blockchain;

storing, via the node, a world state of the current blockchain in the genesis block;

modifying, via the node, the smart contract for the new blockchain;

communicating, via the node, the modified smart contract to the genesis block; and

writing, via the node, one or more potential blockchain transactions to the new blockchain based on an initiating of an open stage on the new blockchain, wherein the initiating of the open stage is based on the creation of the genesis block.

2. The method of claim 1, further comprising: (2) (2)

determining when to close the new blockchain based on a new limited time window; and

changing the new blockchain status to a closing state based on an expiration of the new limited time window.

3. The method of claim 2, comprising: (0) (1)

4. The method of claim 2, further comprising: (1) (2)

responsive to the determining when to close the new blockchain, initiating another new blockchain; and

determining world state information of the new blockchain that will be included in the another new blockchain.

5. The method of claim 4, further comprising: (1) (2)

creating a genesis block associated with the another new blockchain; and

setting a genesis block attribute of the genesis block associated with the another new blockchain to a hash value of a last block of the new blockchain.

6. The method of claim 5, further comprising: (1) (2)

initiating an open stage on the another new blockchain; and

inputting the world state information of the new blockchain in the another new blockchain.

7. The method of claim 6, further comprising: (0) (2)

8. A node of a blockchain system, the node, comprising a processor configured to: (1) (6)

change a status of a current blockchain of the blockchain system to a closed status and a retired status based on expiration of a limited time window defined in a smart contract implemented on the current blockchain;

create a genesis block associated with a new blockchain;

store a world state of the current blockchain in the genesis block;

modify the smart contract for the new blockchain;

communicate the modified smart contract to the genesis block;

write one or more potential blockchain transactions to the new blockchain based on an initiating of an open stage on the new blockchain, wherein the initiating of the open stage is based on the creation of the genesis block.

9. The apparatus of claim 8, wherein the processor is further configured to: (2) (2)

determine when to close the new blockchain based on a new limited time window; and

change the new blockchain status to a closing state based on an expiration of the new limited time window.

10. The apparatus of claim 9, wherein the processor is further configured to: (0) (1)

11. The apparatus of claim 9, wherein the processor is further configured to: (1) (2)

responsive to the determination of when to close the new blockchain, initiate another new blockchain; and

determine world state information of the new blockchain that will be included in the another new blockchain.

12. The apparatus of claim 11, wherein the processor is further configured to: (1) (2)

create a genesis block associated with the another new blockchain; and

set a genesis block attribute of the genesis block associated with the another new blockchain to a hash value of a last block of the new blockchain.

13. The apparatus of claim 12, wherein the processor is further configured to: (1) (2)

initiate an open stage on the another new blockchain; and

input the world state information of the new blockchain in the another new blockchain.

14. The apparatus of claim 13, wherein the processor is further configured to: (0) (2)

15. A non-transitory computer readable storage medium configured to store one or more instructions that when executed by a processor cause the processor to perform: (1) (1)

storing, via the node, a world state of the current blockchain in the genesis block;

modifying, via the node, the smart contract for the new blockchain contracts;

communicating, via the node, the modified smart contract to the genesis block; and writing, via the node, one or more potential blockchain transactions to the new blockchain based on an initiating of an open stage on the new blockchain, wherein the initiating of the open stage is based on the creation of the genesis block.

16. The non-transitory computer readable storage medium of claim 15, further configured to store one or more instructions that when executed by the processor cause the processor to perform: (2) (2)

determining when to close the new blockchain based on a new limited time window; and

changing the new blockchain status to a closing state based on an expiration of the new limited time window.

17. The non-transitory computer readable storage medium of claim 16, further configured to store one or more instructions that when executed by the processor cause the processor to perform: (0) (1)

18. The non-transitory computer readable storage medium of claim 16, further configured to store one or more instructions that when executed by the processor cause the processor to perform: (1) (2)

responsive to the determining when to close the new blockchain, initiating another new blockchain; and

determining world state information of the new blockchain that will be included in the another new blockchain.

19. The non-transitory computer readable storage medium of claim 18, further configured to store one or more instructions that when executed by the processor cause the processor to perform: (1) (2)

creating a genesis block associated with the another new blockchain; and

setting a genesis block attribute of the genesis block associated with the another new blockchain to a hash value of a last block of the new blockchain.

20. The non-transitory computer readable storage medium of claim 19, further configured to store one or more instructions that when executed by the processor cause the processor to perform: (0) (4)

initiating an open stage on the another new blockchain;

including the world state information of the new blockchain in the another new blockchain;

responsive to initiating the open stage on the another new blockchain, transmitting notifications regarding closure of the new blockchain to members of the new blockchain; and

initiating a retiring status to the new blockchain that prevents new transactions from being written to the new blockchain by any member of the blockchain.
