Zero-knowledge
A zero-knowledge service is built so that it has no knowledge of your data — it cannot read your content because it never holds the keys to decrypt it.
What it means
"Zero-knowledge" describes a service architecture where the provider genuinely cannot access your data. The keys live only with you, so the provider has zero knowledge of what you store.
How it differs from "encrypted"
Many services encrypt data "at rest" but hold the keys themselves — meaning they can still read it. Zero-knowledge goes further: the provider never has the keys, so even they cannot decrypt your content.
Why it matters
Zero-knowledge means a breach, a rogue employee, or a legal demand cannot expose your readable data — because the provider has nothing readable to expose.
How Atomic Blend uses it
Atomic Blend is zero-knowledge by design: your data key is sealed with your password and backup phrase, so only you can unlock your data.
