🔗 What Blockchain Really Is

Blockchain is a digital ledger that records transactions across many computers — secure, transparent, and unchangeable. It removes middlemen and builds trust through code, not people.

💡 Lesson from the OneCoin Story:

Always research before investing. OneCoin claimed to be a blockchain but had no real network — it was a scam. Real blockchains are open, verifiable, and decentralized.
