Web3 utilizes three key structural principles that allow secure coordination between completely anonymous global players:
### 1. Trustlessness
This does not mean participants are untrustworthy. Rather, it means **you do not need to rely on the honesty of a human intermediary or bank clerk**. Transactions are written, verified, and strictly enforced by open-source computer code (Smart Contracts).
### 2. Immutability
Once a block of transacting history is agreed upon by consensus and officially written to the public blockchain, it becomes **technically impossible to alter, edit, or delete**. This builds a bulletproof, historically permanent sequence of records.
### 3. Permissionlessness
Anyone with a standard internet connection can participate in Web3 economies. You do not need to request permission from centralized gatekeepers, complete corporate application signups, or fulfill geographic identity filters.
