Blockchain data compression and storage

A non-transitory machine-readable medium having stored thereon machine-readable instructions executable to cause a machine to perform operations comprising:

• receiving a data access request for data associated with a blockchain system that is distributed across a plurality of computer nodes;
• accessing a compressed blockchain associated with the blockchain system via a first computer node of the plurality of computer nodes, wherein the compressed blockchain comprises (i) a first genesis block generated based on a first set of blocks associated with the blockchain system and (ii) a second set of blocks that is chained to the first genesis block;
• determining that the data is not stored in the second set of blocks;
• accessing a root hash value and a database address stored in the first genesis block;
• retrieving the data based on querying a database corresponding to the database address using the root hash value;
• and
• providing the data to a device.

A method comprising:

• receiving a request for accessing data associated with a blockchain system;
• accessing a blockchain associated with the blockchain system, wherein the blockchain comprises (i) a first genesis block generated based on a first plurality of blocks associated with the blockchain system and (ii) a second plurality of blocks chained to the first genesis block;
• determining that the data is not stored in the second plurality of blocks;
• accessing a root hash value and a database address stored in the first genesis block;
• retrieving the data based on querying a database corresponding to the database address using the root hash value;
• and
• providing the data to a device.
