Conflict-free version control
An example operation may include one or more of receiving from a user node, by a blockchain processor node, a document access request containing a document ID, acquiring, by the blockchain processor node, from a blockchain ledger an encrypted URL of the document and a source hash of the document based on the document ID, verifying, by the blockchain processor node, a document received from a document owner's node storage based on a decrypted URL of the document and, in response to the verification, transmitting the document received from the document owner's node storage to the user node.
1. A document processor node of a blockchain network, the document processor node comprising:
a processor that when executing one or more instructions stored in a memory is configured to:
receive a document access request that contains a document ID and an instance ID of a document owner, wherein the document ID is from a user node of the blockchain network;
acquire an encrypted URL (Uniform Resource Locator) of the document and a source hash of the document from a ledger of the blockchain network using the document ID;
request the document from a document owner node using the instance ID, wherein the request comprises the encrypted URL and a public key of the document processor node;
verify the requested document based on a decrypted URL corresponding to the encrypted URL of the document; and
in response to the verification, transmit the document to the user node.
2. The document processor node of claim 1 , wherein the processor is further configured to:
responsive to a verification of the blockchain processor node by the document owner node, receive the document from the document owner node.
3. The document processor node of claim 1 , wherein the processor is further configured to:
verify the document based on a comparison of a hash of the document to the source hash of the document.
4. The document processor node of claim 1 , wherein the processor is further configured to:
decrypt the URL of the document.
5. A method, comprising:
receiving, by a document processor node of a blockchain network, a document access request containing a document ID and an instance ID of a document owner, wherein the document ID is from a user node of the blockchain network;
acquiring, by the document processor node, an encrypted URL (Uniform Resource Locator) of the document and a source hash of the document from a ledger of the blockchain network using the document ID;
requesting, by the document processor node, the document from a document owner node using the instance ID, wherein the request comprises the encrypted URL and a public key of the document processor node;
verifying, by the document processor node, the requested document based on a decrypted URL corresponding to the encrypted URL of the document; and
in response to the verifying, transmitting, by the document processor node, the document to the user node.
6. The method of claim 5 , further comprising:
responsive to a verification of the document processor node by the document owner node, receiving the document from the document owner node.
7. The method of claim 5 , further comprising:
verifying the document by a hash of the document to the source hash of the document.
8. The method of claim 5 , further comprising:
decrypting the URL of the document.
9. A non-transitory computer readable medium comprising one or more instructions that when executed by a processor document processor node in a blockchain network cause the processor to perform:
receiving a document access request containing a document ID and an instance ID of a document owner, wherein the document ID is from a user node of the blockchain network;
acquiring an encrypted URL (Uniform Resource Locator) of the document and a source hash of the document from a ledger of the blockchain network using the document ID;
requesting the document from a document owner node using the instance ID, wherein the request comprises the encrypted URL and a public key of the document processor node;
verifying, by the document processor node, the requested document based on a decrypted URL corresponding to the encrypted URL of the document; and
in response to the verifying, transmitting, by the document processor node, the document to the user node.
10. The non-transitory computer readable medium of claim 9 , wherein the one or more instructions further cause the processor to perform:
responsive to a verification of the document processor node by the document owner node, receiving the document from the document owner node.
11. The non-transitory computer readable medium of claim 9 , wherein the one or more instructions further cause the processor to perform:
verify the document by a hash of the document to the source hash of the document.
