According to online reports, Ronin announced that it will soon return from Ethereum sidechain to Ethereum L2. Four years ago, a separate Ethereum sidechain was established because Axie Infinity needed a faster and more efficient network, and Ethereum's expansion roadmap was still in its infancy. Now that Ethereum is back, transaction costs and speeds are better than ever. Ronin plans to become the gamification engine of Ethereum and will become a fully functional L2 next year.
