Polkadot Blockchain Academy (Hong Kong) — an intensive 5-week, project-heavy program in blockchain engineering, with full-day sessions six days a week covering advanced topics in cryptography, consensus, and Rust-based blockchain development. I worked on the following Rust projects.

Key projects:

• 🔐 Many-Time Pad Cracker: Cracked reused OTP encryptions to explore cryptographic vulnerabilities.
• ⛓️ Custom Blockchain: Built from scratch with its own consensus and data structure layer.
• 💾 UTXO Chain Node: Developed a node supporting chain reorgs, utxo management, and state consistency.
• 🪙 Multi-Token Treasury Pallet (Substrate): Treasury designed for managing multiple tokens and spend proposals.
• 🌳 Merkle Multi-Proof Generator: Built efficient verification proofs for multiple claims in one Merkle tree.
