CAPE System Components

EQS

Service that monitors the state of the CAPE smart contract and provides an API to query that state.

Address Book

The CAPE Address Book maps user addresses to encryption public keys. Users publish their encryption public keys here. This is done by submitting their UserPubKey bundle (that includes both address and encryption public key) and signing the request using the user private key associated with the address. This way, it is infeasible to publish an invalid encryption key for a user.

This public mapping allows a sender to retrieve the encryption key associated with the recipient address. This is particularly important for the freezing feature: when the freezer releases records back to the original owners, it needs to know their encryption keys in order to produce owner memos for them.

The Address Book is a standalone web service.

Relayer

The Relayer is the component of the system that collects transactions from end users and submit them to the CAPE contract.

A faucet service to issue CAPE native assets.
