Application of Blockchain for DATA TRUST in ENTERPRISE DATA ENGINEERING

Businesses, Regulatory compliance (e.g., GDPR) often need a Data Lake / Data Foundation / System-of-Engagement to have Comprehensive Data Trust pillars (audit, provenance, Lineage, Verifiability). But, the Organization (a large FinTech Org) wants to have Future-gen architecture which can provide

  • enablement of the Comprehensive Data Trust pillars (audit, provenance, Lineage, Verifiability)@port-of-entry of System-of-Engagement
      - auditing capability to keep track of critical data 
      - Data Provenance 
      - complete history of assets / Data Lineage
      - Verifiability : a verification mechanism to verify integrity of past records
    
  • Post enablement of DATA TRUST pillars @port-of-entry, it should be able to trigger serverless-processing or serverless-workflows for

      - caching the history for querying in Amazon Elasticsearch, 
      - transforming and loading the data into an Amazon Redshift cluster, and 
      - also storing the data in an Amazon S3 data lake.
    
  • for critical events/ datasets originating from Streaming sources / Batch sources

      - for critical events originating from Streaming sources, such as "*credit* and *debit transactions* across bank accounts", and also
      - for critical datasets originating from Batch sources, such as "*history of assets* for Loan lending to Orgs/customers like vehicle maintenance records /or/ Lending application records".

Application of Blockchain for CIRCULAR SUPPLY CHAIN with IoT

Business Techo Problem statement

  • CIRCULAR SUPPLY CHAIN with IoT
  • Continuous Monitoring & Notification for SAFE ENVIRONMENTAL CONDITION for raw crop produce SHIPMENTs in TRANSPORTATION
  • right credit attribution to the Farmers

  • Enabling SMOOTH ADOPTION of blockchain (HL FABRIC)

    • how to right size the load for blockchain?
    • How to cost optimize the adoption of blockchain?
    • how to manage, deploy, auto-scale, descale container Blockchain network (HL FABRIC)?
    • how to monitor the nodes used for blockchain network cluster?
    • how to secure member's keys created for each member for accessing blockchain network? Possibly securing/fortifying keys in hardware using AWSCloud HSM.

Please Note The fundamental technology of blockchain is cryptography. Cryptography works on KEYS. Hence, Keys become very important part of the solution.
