Document redaction and reconciliation

1. A system comprising:

a memory storing one or more instructions; and

a processor that when executing the one or more instructions is configured to:

split a document provided by a document owner node into a plurality of segments and store the plurality of segments via a blockchain ledger of a blockchain network, wherein a plurality of participant nodes of the blockchain network are assigned different restrictions with respect to the plurality of segments,

receive a proposed change to the document which is input via a view of the document at a participant node among the plurality of participant nodes,

approve the proposed change to the document based on votes on the proposed change collected from the plurality of authorized participant nodes, and

in response to the determination, update a view of the document at a different participant node from among the plurality of participants nodes by redacting a portion of the document based on a smart contract of the blockchain ledger of the blockchain network and the approved proposed change to the document.

2. The system of claim 1 , wherein the processor is further configured to:

send a notification of the update to the document to the plurality of authorized participant nodes.

3. The system of claim 1 , wherein the processor is further configured to:

determine, for the plurality of the participant nodes, view access and edit access for the segment.

4. The system of claim 1 , wherein the processor is further configured to:

receive a consensus method for reconciliation of the proposed change from the document owner node.

5. The system of claim 1 , wherein the processor is further configured to:

assign the plurality of authorized participant nodes to vote on the proposed change to the document.

6. The system of claim 1 , wherein the processor is further configured to:

convert a segment into a blob prior to storage on the blockchain ledger.

7. A method, comprising:

splitting, by a document server of a blockchain network, a document provided by a document owner node into a plurality of segments and storing the plurality of segments via a blockchain ledger of the blockchain network, wherein a plurality of participant nodes of the blockchain network are assigned different restrictions with respect to the plurality of segments;

receiving a proposed change to the document which is input via a view of the document at a participant node among the plurality of participant nodes;

approving the proposed change to the document based on votes on the proposed change collected from the plurality of authorized participant nodes, and

in response to the determination, updating a view of the document at a different participant node from among the plurality of participants nodes by redacting a portion of the document based on a smart contract of the blockchain ledger of the blockchain network and the approved proposed change to the document.

8. The method of claim 7 , further comprising:

sending a notification of the update to the document to the plurality of authorized participant nodes.

9. The method of claim 7 , further comprising:

determining, for the plurality of the participant nodes, view access and edit access for the segment.

10. The method of claim 7 , further comprising:

receiving a consensus method for reconciliation of the proposed change from the document owner node.

11. The method of claim 7 , further comprising:

assigning the plurality of authorized participant nodes to vote on the proposed change to the document.

12. The method of claim 7 , further comprising:

converting a segment into a blob prior to storage on the blockchain ledger.

13. A non-transitory computer readable medium comprising one or more instructions that when executed by a processor of a server in a blockchain network cause the processor to perform:

splitting a document provided by a document owner node into a plurality of segments and storing the plurality of segments via a blockchain ledger of the blockchain network, wherein a plurality of participant nodes of the blockchain network are assigned different restrictions with respect to the plurality of segments;

receiving a proposed change to the document which is input via a view of the document at a participant node among the plurality of participant nodes which is authorized to update the segment within the different access restrictions;

approving the proposed change based on votes on the proposed change collected from the plurality of authorized participant nodes, and

in response to the determination, updating a view of the document at a different participant node from among the plurality of participants nodes by redacting a portion of the document based on a smart contract of the blockchain ledger of the blockchain network and the approved proposed change to the document.

14. The non-transitory computer readable medium of claim 13 , wherein the one or more instructions further cause the processor to perform:

sending a notification of the update to the document to the plurality of authorized participant nodes.

15. The non-transitory computer readable medium of claim 13 , wherein the one or more instructions further cause the processor to perform:

determining, for the plurality of the participant nodes, view access and edit access for the segment.

16. The non-transitory computer readable medium of claim 13 , wherein the one or more instructions further cause the processor to perform:

receiving a consensus method for reconciliation of the proposed change from the document owner node.

17. The non-transitory computer readable medium of claim 13 , wherein the one or more instructions further cause the processor to perform:

assigning the plurality of authorized participant nodes to vote on the proposed change to the document.
