Abstract

A system, method, and computer readable storage medium configured for a transactional database management system shared by all computing nodes participating in a system based on a blockchain protocol. The transactional database management system includes transactions and blocks, where the transactions are data to be stored in the blockchain and the blocks are records that confirm when and in what sequence certain transaction became journaled as part of the blockchain. A request is received signed with a signature of a user system to include a new transaction with additional data in the blockchain. In response to the signature being verified and hash of batches of receive transaction into the block being verified. The block are added that records the new transaction with additional data in the blockchain using within the transactional database management system.

Claims

1. A computer-based method comprising:

accessing, by a processor, a transactional database management system shared by all computing nodes participating in a system based on a blockchain protocol, the transactional database management system including transactions and blocks, where the transactions are data to be stored in the blockchain and the blocks are records that confirm when and in what sequence certain transaction became journaled as part of the blockchain;

receiving a request signed with a signature of a user system to include a new transaction with additional data in the blockchain;

in response to the signature being verified and hash of batches of receive transaction into the block being verified

adding a block that records the new transaction with additional data in the blockchain using within the transactional database management system which is treated as coherent, independent of other changes to the transactional database management system, and only commits the new transaction into the transactional database management system if no errors occur otherwise the new transaction is rolled back and not committed into the transactional database management system.

2. The computer-based method of claim 1, wherein the transactional database management system is defined as a hierarchical structure in which data is organized in a series of levels using nodes and branches, with each child node only having branched linked to one higher level parent node.

3. The computer-based method of claim 1, wherein the transactional database management system is defined as a network structure in which data is organized using nodes and branches with each child node linked to multiple parent nodes.

4. The computer-based method of claim 1, wherein the transactional database management system is defined as a relational structure in which data is organized in a series of related tables.

5. The computer-based method of claim 1, wherein the transactional database management system is defined as a network structure in which data is organized using nodes and branches with each child node linked to multiple parent nodes with a relational structure in which data is organized in a series of related tables.

6. The computer-based method of claim 1, wherein the transaction in the transactional database management system is defined as atomic, consistent, isolated, and durable (ACID).

7. The computer-based method of claim 1, wherein the transaction in the transactional database management system is defined as basically available, software state, eventual consistency (BASE).

8. The computer-based method of claim 1, wherein the adding the block that records the new transaction with additional data in the blockchain includes a hash of a previous block.

9. The computer-based method of claim 8, wherein the adding the block that records the new transaction with additional data in the blockchain includes a timestamp.

10. The computer-based method of claim 8, wherein the adding the block that records the new transaction with additional data in the blockchain includes a transaction identifier.

11. The computer-based method of claim 1, further comprising:

receiving a request with a transaction identifier from a user system to access data journaled as part of the blockchain in the transactional database management system shared by all computing nodes participating in a system based on a blockchain protocol;

searching the transactional database management system using the identifier for a corresponding block in the blockchain; and

in response to finding the corresponding block in the blockchain making available the data that has been decrypted to the user system.

12. The computer-based method of claim 11, wherein the making available the data that has been decrypted includes making available a category associated with the data.

13. A system comprising:

a memory;

a processor communicatively coupled to the memory, where the processor is configured to perform

accessing, by a processor, a transactional database management system shared by all computing nodes participating in a system based on a blockchain protocol, the transactional database management system including transactions and blocks, where the transactions are data to be stored in the blockchain and the blocks are records that confirm when and in what sequence certain transaction became journaled as part of the blockchain;

receiving a request signed with a signature of a user system to include a new transaction with additional data in the blockchain;

in response to the signature being verified and hash of batches of receive transaction into the block being verified

adding a block that records the new transaction with additional data in the blockchain using within the transactional database management system which is treated as coherent, independent of other changes to the transactional database management system, and only commits the new transaction into the transactional database management system if no errors occur otherwise the new transaction is rolled back and not committed into the transactional database management system.

14. The system of claim 13, wherein the transactional database management system is defined as a hierarchical structure in which data is organized in a series of levels using nodes and branches, with each child node only having branched linked to one higher level parent node.

15. The system of claim 13, wherein the transactional database management system is defined as a network structure in which data is organized using nodes and branches with each child node linked to multiple parent nodes.

16. The system of claim 13, wherein the transactional database management system is defined as a relational structure in which data is organized in a series of related tables.

17. The system of claim 13, wherein the transactional database management system is defined as a network structure in which data is organized using nodes and branches with each child node linked to multiple parent nodes with a relational structure in which data is organized in a series of related tables.

18. The system of claim 13 wherein the transaction in the transactional database management system is defined as atomic, consistent, isolated, and durable (ACID).

19. The system of claim 13, wherein the transaction in the transactional database management system is defined as basically available, software state, eventual consistency (BASE).

20. A non-transitory computer program product comprising a computer readable storage medium having computer readable program code embodied therewith, the computer readable program code configured to perform:

accessing, by a processor, a transactional database management system shared by all computing nodes participating in a system based on a blockchain protocol, the transactional database management system including transactions and blocks, where the transactions are data to be stored in the blockchain and the blocks are records that confirm when and in what sequence certain transaction became journaled as part of the blockchain;

receiving a request signed with a signature of a user system to include a new transaction with additional data in the blockchain;

in response to the signature being verified and hash of batches of receive transaction into the block being verified; and

adding a block that records the new transaction with additional data in the blockchain using within the transactional database management system which is treated as coherent, independent of other changes to the transactional database management system, and only commits the new transaction into the transactional database management system if no errors occur otherwise the new transaction is rolled back and not committed into the transactional database management system.
