Key terms

Decentralization

The distribution of power, control, and decision-making away from a central authority across a network of participants. Vitalik distinguishes three types: architectural, political, and logical.

Censorship resistance

The property of a system that prevents any single authority from blocking or reversing valid transactions. A core selling point of well-designed decentralized systems.

Single point of failure

A component in a system whose failure would cause the entire system to stop functioning. Decentralization aims to eliminate or minimize these.

Sovereignty

In crypto context, the ability of individuals to have full control over their own assets and data without depending on third parties. "Self-sovereignty" is a related term.

Trustless system

A system where participants do not need to trust each other or a central authority because rules are enforced transparently by code. Better termed "trust-minimized."

Permissionless

A system that anyone can join, use, or build on without needing approval from any authority. Opposite of permissioned (where access is gated).

Permissioned blockchain

A blockchain where participants must be approved to read or write. Used by enterprise blockchains; sacrifices decentralization for performance and compliance.

De-banking

When a financial institution closes a customer account or refuses service based on factors like industry, political views, or government pressure rather than credit. A primary motivator for decentralized alternatives.

Self-custody

Holding your own private keys rather than relying on a third party (like an exchange) to hold them. The phrase "not your keys, not your coins" captures this principle.
