METHODS AND DEVICES FOR PROVIDING TRAVERSABLE KEY-VALUE DATA STORAGE ON BLOCKCHAIN

摘要

Disclosed herein are methods, devices, and apparatuses, including computer programs stored on computer-readable media, for providing traversable key-value data storage. One of the methods includes: receiving a first user-provided key-value pair for recordation on a storage system, the first user-provided key-value pair comprising a first user-provided key and a first user-provided value; assigning a first index to the first user-provided key-value pair; generating a first index-to-key key-value pair, the first index-to-key key-value pair having a key comprising the first index and a value comprising the first user-provided key; generating a first key-to-index key-value pair, the first key-to-index key-value pair having a key comprising the first user-provided key and a value comprising the first index; and storing the first user-provided key-value pair, the first index-to-key key-value pair, and the first key-to-index key-value pair on the storage system.
