Want to master blockchain? Start with the core: a tamper‑proof ledger stored across nodes, secured by consensus algorithms like Proof‑of‑Work or Proof‑of‑Stake. For beginners, focus on transactions, addresses, and wallets. Experts dive into smart contracts, layer‑2 scaling, zk‑SNARKs, and cross‑chain bridges. Build, test, audit, and join the community—your first step is a single block.
