Merkle Trees 101 (Part 1): Structure, Proofs, and Real-World Uses

Part one of this series breaks down Merkle trees from first principles, starting with basic tree data structures and traversal methods before introducing hierarchical cryptographic hashing. It explains how inclusion proofs work and why Merkle trees scale logarithmically, making them essential for blockchain networks, distributed filesystems, version control systems, and peer-to-peer infrastructure.
