4.0 Data and Storage¶

The Data and Storage component defines how the MBI platform manages, validates, and stores information across on-chain and off-chain systems. It ensures security, performance, and reliability while maintaining compliance with blockchain standards.

4.1 Data Flow (On-Chain vs Off-Chain)¶

Status: Pending Completion

The data flow design currently exists at the product layer, while integration at the MBI Platform level is still pending.

On-Chain Data Storage¶

On-Chain Data

Purpose: Ensures data integrity and immutability

Only critical information is stored directly on the blockchain:

Transaction hashes
Digital signatures
Reference identifiers
Smart contract states

Off-Chain Data Storage¶

Off-Chain Data

Purpose: Optimizes performance and reduces costs

Application data is stored in secure external systems:

Application metadata
Large payloads and files
User-generated content
Query-optimized databases

4.2 Invalid Data Handling¶

Status: Pending Completion

Documentation for invalid data handling procedures is currently under development.
