Challenges & Solutions
UTXO Management System
Designed and implemented an efficient UTXO (Unspent Transaction Output) system to track available funds and prevent double-spending, requiring careful state management and validation logic throughout the transaction lifecycle.
Cryptographic Security Implementation
Incorporated robust cryptographic primitives using ED25519 signatures and SHA3-256 hashing to ensure transaction authenticity and blockchain integrity, balancing security requirements with performance considerations.
Consensus and Validation
Created a Proof of Work consensus mechanism with multi-level validation to ensure blockchain consistency across nodes, properly managing mining rewards, transaction verification, and maintaining an immutable ledger structure.
My Role
Architect and developer responsible for designing the cryptocurrency framework, implementing core blockchain components, transaction handling systems, and cryptographic operations. Focused on creating a modular, secure, and educational implementation.
