Abstract

A blockchain of transactions may be referenced for various purposes and may be later accessed for ledger verification. One example operation may include one or more of identifying a plurality of rules defining a temporary private blockchain, creating a private blockchain block comprising the plurality of rules defining the temporary private blockchain, transmitting an update to a private blockchain block, and designating the temporary private blockchain closed responsive to receiving the update.

First claim

What is claimed is:

1. A method, comprising:
identifying a plurality of rules defining a temporary private blockchain;
creating a private blockchain block comprising the plurality of rules defining the temporary private blockchain;
transmitting an update including a conclusion block comprising a conclusion flag and a public key to a private blockchain block;
designating the temporary private blockchain closed responsive to receiving the update; and
designating the private blockchain as part of a public blockchain and storing a checksum signature of transactions on the private blockchain in the public blockchain based on the conclusion block being processed.

2. The method of claim 1 , wherein the update comprises a public key.

3. The method of claim 1 , further comprising:
generating a private key to sign and verify a communication session outside the private blockchain.

4. The method of claim 1 , further comprising:
designating the temporary private blockchain abandoned, responsive to the update being transmitted.

5. The method of claim 1 , further comprising:
linking the public blockchain to a plurality of transactions on the private blockchain via the public key and a private key.

6. An apparatus, comprising:
a processor configured to:
identify a plurality of rules defining a temporary private blockchain,
create a private blockchain block comprising the plurality of rules defining the temporary private blockchain; and
cause a transmitter to transmit an update including a conclusion block comprising a conclusion flag and a public key to a private blockchain block;

designate the temporary private blockchain closed responsive to receiving the update; and
designate the private blockchain as part of a public blockchain and storing a checksum signature of transactions on the private blockchain in the public blockchain based on the conclusion block being processed.

7. The apparatus of claim 6 , wherein the update comprises a public key.

8. The apparatus of claim 6 , wherein the processor is further configured to:
generate a private key to sign and verify a communication session outside the private blockchain.

9. The apparatus of claim 6 , wherein the processor is further configured to:
designate the temporary private blockchain abandoned, responsive to the update being transmitted.

10. The apparatus of claim 6 , wherein the processor is further configured to:
link the public blockchain to a plurality of transactions on the private blockchain via the public key and a private key.

11. A non-transitory computer readable storage medium configured to store at least one instruction that when executed by a processor causes the processor to perform:
identifying a plurality of rules defining a temporary private blockchain;
creating a private blockchain block comprising the plurality of rules defining the temporary private blockchain;
transmitting an update including a conclusion block comprising a conclusion flag and a public key to a private blockchain block;
designating the temporary private blockchain closed responsive to receiving the update; and

designating the private blockchain as part of a public blockchain and storing a checksum signature of transactions on the private blockchain in the public blockchain based on the conclusion block being processed.

12. The non-transitory computer readable storage medium of claim 11 , wherein the update comprises a public key.

13. The non-transitory computer readable storage medium of claim 11 , further configured to store at least one instruction that when executed by the processor causes the processor to perform:
generating a private key to sign and verify a communication session outside the private blockchain.

14. The non-transitory computer readable storage medium of claim 11 , further configured to store at least one instruction that when executed by the processor causes the processor to perform:
designating the temporary private blockchain abandoned, responsive to the update being transmitted.

15. The non-transitory computer readable storage medium of claim 11 , further configured to store at least one instruction that when executed by the processor causes the processor to perform:
linking the public blockchain to a plurality of transactions on the private blockchain via the public key and a private key.
