Vitalik signs the "No Trust Declaration", emphasizing that the system relies solely on mathematics and Consensus.

On November 13, Vitalik Buterin tweeted that he has signed The Trustless Manifesto. This manifesto was authored by Yoav Weiss, Vitalik Buterin, and Marissa Posner, and defines a “trustless” system as one in which any honest participant can join, verify, and act without permission. The core requirements include self-sovereignty, verifiability, censorship resistance, Walkaway test, accessibility, and incentive transparency. The content includes the “Three Laws”: 1. No critical secrets (protocol steps do not rely on private information of a single actor); 2. No indispensable intermediaries (participants are replaceable and open); 3. No unverifiable outcomes (state changes can be reproduced from public data). Trustless designs need to be embedded from the start to avoid convenience leading to reliance on intermediaries (such as custodial RPC or centralized ordering). For Ethereum, the manifesto emphasizes maintaining user-initiated actions, verifiability, inclusivity, and code-driven logic to achieve trusted neutrality. Trustlessness is not a post-facto feature, but rather foundational; otherwise, efficiency, user experience, and scalability are merely decorations on a fragile core.
