Abstract

A digital currency management method and a digital currency node apparatus for a digital currency network based on a block-chain are provided. The method includes: determining whether a transaction is generated, performing a proof-of-work mechanism if the transaction is generated. The method also includes: not performing the proof-of-work mechanism if no transaction is generated. In addition, the proof-of-work mechanism includes: obtaining a pre-block and calculating a pre-hash value of the pre-block; and finding a current verification value according to the pre-hash value. Accordingly, a newly generated transaction could be processed immediately and the waste of computing resource in the digital currency network could be reduced.

Claims

1. A digital currency management method, adapted for a digital currency network based on a block-chain, the digital currency management method comprising:

determining whether a transaction is generated;

performing a proof-of-work mechanism if the transaction is generated, wherein the step of performing the proof-of-work mechanism comprises;

obtaining a pre-block and calculating a pre-hash value of the pre-block; and

finding a current verification value of a current block according to the pre-hash value, wherein the current verification value is for verifying validity of the current block; and

not performing the proof-of-work mechanism if no transaction is generated.

2. The digital currency management method according to claim 1, further comprising:

publishing the current verification value if the current verification value of the current block is found.

3. The digital currency management method according to claim 2, further comprising:

not obtaining a reward corresponding to the found current verification value of the current block.

4. The digital currency management method according to claim 1, further comprising:

receiving a to-be-confirmed verification value corresponding to a to-be-confirmed block; and

verifying validity of the to-be-confirmed block according to the to-be-confirmed verification value.

5. The digital currency management method according to claim 1, further comprising:

adjusting, dynamically, a difficulty degree of finding the current verification value used in the proof-of-work mechanism from a first difficulty degree to a second difficulty degree, wherein the first difficulty degree and the second difficulty degree are different.

6. A digital currency node apparatus, adapted for a digital currency network based on a block-chain, the digital currency node apparatus comprising:

a storage unit, configured to store a plurality of modules; and

a processor, coupled to the storage unit and configured to load and execute the modules from the storage unit to;

determine whether a transaction is generated; and

perform a proof-of-work mechanism if the transaction is generated, wherein the proof-of-work mechanism comprises;

obtaining a pre-block and calculating a pre-hash value of the pre-block; and

finding a current verification value of a current block according to the pre-hash value, wherein the current verification value is for verifying validity of the current block,

wherein the processor does not perform the proof-of-work mechanism if no transaction is generated.

7. The digital currency node apparatus according to claim 6, wherein the processor is further configured to load and execute the modules from the storage unit to:

publish the current verification value if the current verification value of the current block is found.

8. The digital currency node apparatus according to claim 7, wherein the digital currency node apparatus does not obtain a reward corresponding to the found current verification value of the current block.

9. The digital currency node apparatus according to claim 6, wherein the processor is further configured to load and execute the modules from the storage unit to:

receive a to-be-confirmed verification value corresponding to a to-be-confirmed block; and

verify validity of the to-be-confirmed block according to the to-be-confirmed verification value.

10. The digital currency node apparatus according to claim 6, wherein the processor is further configured to load and execute the modules from the storage unit to:

adjust, dynamically, a difficulty degree of finding the current verification value used in the proof-of-work mechanism from a first difficulty degree to a second difficulty degree, wherein the first difficulty degree and the second difficulty degree are different.
