Why are Merkle trees crucial for blockchain scalability?
They allow light clients to verify that a transaction is included in a block using only O(log N) hashes instead of downloading the entire block history.
Build interactive Merkle Trees from transaction hashes, calculate the cryptographic root hash, and verify audit path inclusion proofs with visual graphs.
