What standardising on an oracle network actually asks of the node operators underneath it.

For chain infrastructure, where the assets at stake are keys rather than data, the real questions are legal jurisdiction and physical auditability.

What one does, how it differs from a validator node, and what it actually requires once the chain it serves gets busy.
