US Patent 11860856 Managing distributed ledger storage space

An example operation includes one or more of receiving a block, extracting information from the block, correlating an identifier to the information as previously stored in a first storage area, replacing the information in the block with the identifier, and submitting the block with the identifier for storage in a second storage area. The identifier links to the information previously stored in the first storage area in order to allow for recovery of the information, and at least the second storage area is in a blockchain.
