Nonces & Mining Math
The nonce field, the astronomical odds of finding a valid hash, and why miners iterate quintillions of guesses.

Merkle Trees
How hashing transactions into a tree yields a compact root, and how SPV wallets prove inclusion without the full block.

Merkle Patricia Tries
Ethereum's state structure — how Merkle tries store accounts, storage, and receipts and enable fast state proofs.

Hash Commitments & Preimages
How committing to a hash hides a value until reveal, and where commitments underpin protocols and proofs.

Bloom Filters
How light clients probabilistically request relevant transactions without revealing which addresses they own.

Key Derivation (BIP32/39/44)
From mnemonic seed to master key to child keys — the HD wallet derivation paths behind every modern wallet.

The Quantum Threat
How Shor's and Grover's algorithms threaten ECDSA and hashes, and the post-quantum signature migration ahead.
