Abstract

A blockchain of transactions may be referenced for various purposes and may be later accessed by interested parties for ledger verification. One example operation may comprise one or more of identifying determining a shared file is being edited by one or more entities, identifying one or more changes to the shared file while the shared file is being edited, signing the one or more changes with one or more public keys, and adding the one or more changes to a blockchain.

First claim

What is claimed is:

1. A computer-implemented method, comprising:
receiving, by a blockchain, an edited version a document from one at least one of a first entity and a second entity configured to coedit the document;
identifying, by the blockchain, that a complexity required to validate an edit of the edited document exceeds a threshold value; and
creating, by the blockchain, a new version of the document and a new blockchain associated with the new version of the document.

2. The computer-implemented method of claim 1 , wherein the creating a new blockchain further comprises:
creating a genesis block of the new blockchain based on the new document.

3. The computer-implemented method of claim 1 , further comprising:
editing a privileged portion of the document.

4. The computer-implemented method of claim 1 , wherein the identifying that a complexity required to validate an edit of the edited document exceeds a threshold value further comprises at least one of:
identifying that a time required to validate the edit exceeds a threshold time; and
identifying that an amount of computing resources required to validate the edit exceeds a threshold amount.

5. The computer-implemented method of claim 1 , further comprising:
signing the edit with a public key.

6. The computer-implemented method of claim 1 , wherein the new version of the document does not contain edits.

7. The computer-implemented method of claim 6 , wherein the document comprises:
a plurality of different regions, each region associated with a corresponding sidechain of the blockchain, wherein two or more of the plurality of regions each contain a corresponding edit, and
wherein the method further comprises:
identifying that a complexity required to validate an edit of the two or more corresponding edits exceeds a threshold value.

8. A blockchain, comprising:
a processor configured to execute one or more instruction stored in a memory to configure the processor to:
receive an edited version a document from one at least one of a first entity and a second entity configured to coedit the document;
identify that a complexity required to validate an edit of the edited document exceeds a threshold value; and
create a new version of the document and a new blockchain associated with the new version of the document.

9. The blockchain of claim 8 , wherein, when the processor is configured to create a new blockchain, the processor is further configured to:
create a genesis block of the new blockchain based on the new document.

10. The blockchain of claim 8 , wherein the processor is further configured to:
edit a privileged portion of the document.

11. The blockchain of claim 8 , wherein, when the processor is configured to identify that a complexity required to validate an edit of the edited document exceeds a threshold value, the processor is further configured to, at least one of:
identify that a time required to validate the edit exceeds a threshold time; and
identify that an amount of computing resources required to validate the edit exceeds a threshold amount.

12. The blockchain of claim 8 , wherein the processor is further configured to:
sign signing the edit with a public key.

13. The blockchain of claim 8 , wherein the new version of the document does not contain edits.

14. A non-transitory computer readable storage medium storing one or more instructions that when executed by a processor of a blockchain cause a processor to perform:
receiving an edited version a document from one at least one of a first entity and a second entity configured to coedit the document;
identifying that a complexity required to validate an edit of the edited document exceeds a threshold value; and
creating a new version of the document and a new blockchain associated with the new version of the document.

15. The non-transitory computer readable storage medium of claim 14 , wherein the creating a new blockchain further comprises:
creating a genesis block of the new blockchain based on the new document.

16. The non-transitory computer readable storage medium of claim 14 , wherein the one or more instructions further cause the processor to perform:
editing a privileged portion of the document.

17. The non-transitory computer readable storage medium of claim 14 , wherein the identifying that a complexity required to validate an edit of the edited document exceeds a threshold value further comprises at least one of:
identifying that a time required to validate the edit exceeds a threshold time; and
identifying that an amount of computing resources required to validate the edit exceeds a threshold amount.

18. The non-transitory computer readable storage medium of claim 14 , wherein one or more instructions further cause the processor to perform:
signing the edit with a public key.

19. The non-transitory computer readable storage medium of claim 14 , wherein the new version of the document does not contain edits.

20. The non-transitory computer readable storage medium of claim 19 , wherein the document comprises:
a plurality of different regions, each region associated with a corresponding sidechain of the blockchain, wherein two or more of the plurality of regions each contain a corresponding edit, and
wherein the one or more instructions further cause the processor to perform:
identifying that a complexity required to validate an edit of the two or more corresponding edits exceeds a threshold value.
