Dev Meetup Kyiv #1

• 📍 BIockchain Hub
• 🎓 What kind of cryptography is used in Bitcoin crypto wallets

At Dev Meetup Kyiv #1, Vadim Grusha discussed key aspects of cryptography in Bitcoin, the principles of cryptocurrency wallets, and the mechanics of deterministic keys. The talk covered digital signature algorithms, entropy generation and recovery, the structure of cryptocurrency addresses, and different wallet types. Security concerns, hierarchical wallet usage, and the implementation of SegWit in Bitcoin were also explored.

• 🔹 How hierarchical keys are generated and why they matter
• 🔹 How Bitcoin addresses work and why there are multiple types
• 🔹 What entropy, mnemonic phrases, and PBKDF2 are and how they function
• 🔹 How SegWit increased block capacity without a hard fork
• 🔹 What security risks wallets face and how to mitigate them
