Prediction,

Ryan Walsh is a great British level fighter, has probably been the most successful of the Walsh brothers, has keeps defending his title, he fell short at European level, but I think he can win a European title. Paulin is 12-0, not many fights, he has been 10 rounds, but he hasn't fought many decent opponents if any (beat a couple of unbeaten fighters, but not experienced or previously tested fighters), his recoed suggests he is a non-puncher, 25% KOs, he might hit harder than that, because all though he has beaten a lot of very limited opponents with losing records, a lot of them rarely get stopped, but he certainly hasn't proven he can punch, Paulin. Paulin has been out of the ring for 13 months, so inactivity is highly likely to be an issue.

I think Walsh will have too much experience, will pressure Paulin, gradually break him down, might stop him late, might go this distance, but I think Walsh wins this fairly easily.
