01
The principle
Sharing adds a participant.
It keeps the origin.
A researcher shares one exact definition with a collaborator. The researcher remains its origin; the collaborator receives independently controlled access.
{ A }One origin
{ A, B }Expanded access
02
The exchange
One artifact. One version.
A traceable connection.
KEP is designed to bind an encrypted artifact, its origin identity, and each recipient to an auditable record. The content stays unchanged as access expands.
03
The protocol
Private knowledge.
Verifiable access.
Encrypted knowledge stays off-chain. The protocol design gives recipient keys, artifact commitments, and the public record distinct roles.
