So in the code outlined, I am submitting a job composed of a txid (bbdb1113e161b7ce4e9f5337afe7a286da2514d33b01638fccfc589609241597) and adding 0.00052 difficulty to it, by creating a hex of that transaction and then signing/spending with my wallet? Then, optionally, I can take the signed hex and POST it to the boost server to have it likely mined faster. Is this accurate?
