9. The method of claim 1 , wherein:
the digital asset represents a value of the tangible asset.
10. The method of claim 1 , further comprising:
obtaining one or more blocks of the blockchain;
extracting, from the one or more obtained blocks, one or more blockchain transactions associated with a third blockchain account of the blockchain; and
determining, based on the one or more extracted blockchain transactions, a quantity of the digital asset in the third blockchain account.
11. The method of claim 1 , further comprising:
obtaining one or more blocks of the blockchain;
extracting, from the obtained one or more blocks, one or more blockchain transactions invoking the blockchain contract; and
determining a transaction history associated with the digital asset based on the one or more extracted blockchain transactions.
12. The method of claim 1 , wherein the blockchain is maintained by a plurality of blockchain nodes, wherein one or more of the blockchain nodes correspond to:
one or more asset exchange institutions; or
one or more asset exchange regulatory agencies.
13. A non-transitory computer-readable storage medium for digital asset management, configured with instructions executable by one or more processors to cause the one or more processors to perform operations comprising:
obtaining a request for creating a digital asset corresponding to a tangible asset, wherein the request comprises:
