The primitive.

full primer →

Every brush preset exchange action is signed with a Winternitz one-time key that is burned on use, so painters watch a hash-chain of verified entries grow instead of trusting a database row.

Why this primitiveLoading details…

Kernel
a Winternitz One-Time Signature (WOTS+) generated with @quip.network/hashsigs, where every action burns the next one-time key and extends an immutable hash-chain of ownership
Drives the UI as
a growing chain of signed entries, each with its nonce, signature digest and a live 'verified' tick
