Crypto Tech Week

Unlocking the core tech behind Bitcoin—one day, one concept, five key points. Simple, smart, and straight to the chain.

Day 5: The Magic of Consensus

Without trust, crypto dies. Consensus makes it work.

1. No Central Authority: Everyone checks, no one rules.

2. 51% Attack: If someone controls most of the power, they could cheat—but it’s expensive.

3. Longest Chain Wins: The network follows the chain with the most work.

4. Forks: When there’s a disagreement, the chain can split (hello, Bitcoin Cash).

5. Trustless Doesn’t Mean Untrustworthy: It just means the system works without needing trust.
