	At a high level, the lookout service receives input via two sources: block events and it's database. Incoming state updates are continually written to the database, and are made available to the lookout as soon as the tower successfully persists the encrypted blob. As new blocks come in, the tower searches for any breach hints matching the txid prefixes contained in the newly found block. If any matches are generated from the query, the lookout service will dispatch an attempt to decrypt and sweep the transaction on behalf of the user.

			= Fees =
			Watchtowers have a "sweep fee". The way watchtowers work is that you give them an encrypted Bitcoin justice transaction getting your funds back in the case of a breach. When they see that evil thieving transaction on the chain, that transaction reveals the decryption key and they decrypt and broadcast the transaction.
