Blockchain Made Simple: It Doesn’t Get Easier Than This

05.01.2023

Blockchain isn’t magic — it’s just a smart table that no one can fake. Think of it as a digital ledger where every record is saved forever, and everyone sees the same version. 1. It’s Like a Chain of RecordsThe word "blockchain" means "a chain of blocks."Each block is like a page where it's recorded:who sent cryptocurrency to whom,when it happened,and how much. Once the block is full, it gets “sealed” forever and added to the previous ones. That creates the chain — the blockchain. 2. You Can’t Fake a BlockEach block has a unique digital fingerprint (hash).If someone changes even one character — the hash changes, and the whole chain breaks. The network quickly notices and rejects the tampered version. 3. Everyone Stores EverythingBlockchain runs on thousands of computers at once — that’s called decentralization.Every participant has a full copy of the chain.No one can secretly erase or edit the records. 4. Who Adds New Blocks?That’s done by miners or validators, depending on the network.They verify transactions and add them to a new block. For this, they earn rewards — for example, in BTC or ETH. In Summary:Blockchain is like a public, secure transaction log.Nothing can be deleted, faked, or hidden.It works automatically and without a central authority — only with the help of the network itself.
