This strategy is mostly the same as UniswapStrategy since Sushi forked their code. However, Sushi added features for additional incentives, e.g. Sushi and xSushi. This strategy has an additional method harvest to occasionally convert earned Sushi into a balance of senior and junior assets to reinvest into LP tokens. Of course, those LP tokens are placed into Masterchef, which earns Sushi, that is again harvested to reinvest into LP tokens. The cycle continues.
