🎉 Minimal Blockchain Learning CLI

Basic Block-chain + mining concept using python

Cryptography-driven offline payment simulation using AES-256-GCM, ECDSA signatures, ECDH key exchange, and immutable hash-chained ledgers.

Interactive Merkle Tree Visualizer for Database Replication: Simulate efficient data sync using hash trees in distributed systems. Build trees, compare roots, drill down mismatches, and sync only changes—perfect for learning anti-entropy in DBs like Cassandra or DynamoDB.
