➰04. Service Data Flow

The BLOCKSTREET Service data and personal information data are registered on the blockchain through hash codes and off-chain logic in the following scenario. Personal data is issued and stored in the form of a unique HASH CODE at the time of registration. The HASH CODE is immutable because it contains information about the location path and storage for this information, and is used to call journal information by registering verification information for this file on each node.

However, it is currently very difficult to store all data about the BLOCKSTREET Service information in blocks, so we store the most core data of transactions occurring in a limited block in the form of CORE INDEX through an internal network,
