    \caption{The core of the on-chain protocol implements an upgradeable, decentralized pub-sub 
    network. Insight consumers publish consent contracts via the consent contract factory which is 
    upgradable by the Protocol DAO. The EOA which publishes a consent contract receives the 
    $DEFAULT\_ADMIN\_ROLE$ associated with that contract.}
