The phrase "In the world of Bitcoin, you don't need to trust anyone — code is law" (English: "In Bitcoin, don't trust, verify – code is law") reflects a core philosophy of Bitcoin and blockchain technology:

1. No need for personal trust: Bitcoin is designed to function without relying on trust in individuals, intermediaries, or governments. Instead of trusting someone to do the right thing, the system requires everyone to follow rules that are pre-defined and encoded.

2. Code is law: Every operational rule of Bitcoin — such as the 21 million BTC supply cap, 10-minute block time, and the proof-of-work consensus algorithm — is written into open-source code. Anyone can view, inspect, and verify it. No one can unilaterally change the rules without consensus from the network.

3. Don't trust, verify: This is a spirit of resistance against centralized systems, where people are forced to place trust in third parties (like banks or governments). With Bitcoin, anyone can run a full node to independently verify every transaction, block, and network rule — without depending on anyone else.
