Trustless
blockchain · security
A property where users rely on verifiable protocol rules instead of trusting a central operator or counterparty.
A trustless system reduces the need to trust people or institutions by making rules enforceable through cryptography, consensus, and open verification. Users can check state and authorize actions with their own keys.
Trustless does not mean risk-free. Users may still trust wallet software, bridge operators, oracle feeds, contract code, hardware, or social recovery processes depending on the system.
