信任機制

Why do we keep money in the bank? Because we need an 'intermediary' to prove how much money I have. But what if the bank goes bankrupt or the system crashes?
Blockchain technology solves this trust issue. It's like a cloud-based super ledger, where every participant (node) keeps a copy of the same transaction record. Once written, it cannot be unilaterally altered or deleted. This is what is known as 'decentralization'.
Bitcoin (BTC) is the first successful application of blockchain technology. When you buy Bitcoin, you are not just buying an asset; you are investing in a global financial network that 'works without banks'. This is currently the safest and most powerful blockchain network in the world.
