Abstract
Described in detail herein is a nested blockchain system. The nested blockchain system can include distributed nodes in a network. A node is configured to generate a master cryptographically verifiable distributed ledger represented by a sequence of blocks. The node spawns a first sub cryptographically verifiable ledger represented by a first genesis block containing a hash value referencing the first block generated in the master cryptographically verifiable ledger, in response to a first event. The node purges the first sub cryptographically verifiable ledger, in response to a second event.
