zk-dex-glossary
Glossary of core terms used in Tokamak's zk-DEx project. Based on the ZKDIPs documents and zkdex-utils source code.
Term Definitions
ZKDIP (ZK-DEX Improvement Proposal)
A proposal document that defines standards for the zk-DEx platform. It specifies protocol specifications, client APIs, contract standards, and more.
zk Address
A destination identifier in zk-DEx for receiving assets. Multiple zk addresses can exist under a single Ethereum account.
- Generation:
zk+ base58(sha256(pubkey.x + pubkey.y)[12:]) - Example:
zk2aGHYonwumtLAG7SNKjharksCP3r
Note
A unit representing an asset in zk-DEx. Like a physical cash note, it contains information such as owner, value, type, viewKey, and salt.
Note Hash
The unique hash value of a note. Used as the asset's address, calculated as sha256(owner + value + type + viewKey + salt).
View Key
A key that allows the note owner to grant third parties the ability to view the note. Only the owner can spend the asset, but the view key enables read-only access.
Salt
A random number used to ensure the uniqueness of a note. Allows different notes to be created even with identical information.
OwnerType
Specifies the type of note owner.
- External: A regular external account (e.g., Ethereum address)
- Note: When another note is the owner (smart note)
Note
This glossary is based on ZKDIP-2, ZKDIP-5, and the Account.js, Note.js files in the zkdex-utils library.
