Blockchain isn't just Bitcoin. At its core, it's a tamper‑proof ledger that anyone can audit. For beginners: think of it as a shared spreadsheet where each row is a block linked by cryptographic hashes. Experts look beyond to layer 2 scaling, sharding, consensus algorithms like PoS, and cross‑chain bridges. Master the basics, then explore the protocols shaping the future.
