Technology & Cryptography - Discusses Zcash and its underlying technology [1] - Explores the concepts of Zero-Knowledge (ZK) proofs and their functionality for both technical and non-technical audiences [1] - Covers methods for scaling Bitcoin [1] - Compares different cryptographic techniques: Fully Homomorphic Encryption (FHE), Multi-Party Computation (MPC), Zero-Knowledge (ZK), and Trusted Execution Environments (TEE) [1] - Mentions Layer 2 solutions like Starkware and Base [1]

Bitcoin Scaling & Immutability - On-chain scaling faces inherent limitations to maintain immutability [1] - Block space scarcity is crucial for preserving Bitcoin's immutability [1] Transaction & Payment Solutions - Economic incentives drive smaller payments towards second layers [1] - Lightning Network facilitates fast and cheap Bitcoin transactions [1]
