Sidechain certificate creator
In the Cardano sidechain toolkit, a sidechain certificate creator is a sidechain component whose responsibilities are:
To accrue data on the sidechain that needs to be ferried to the main chain (hoard)
To inform the governing committee (block producers) of the sidechain that it is time to certify the hoarded data (prove)
To make the proof available for the ferrying mechanism (rely).
