Steem has already proven itself as the fastest and most heavily transacted public blockchain in existence, and scalability continues to remain a top focus of ours. We know that scaling challenges will never completely go away, which is why we plan to continue innovating to ensure that whatever growth comes our way - we'll be ready
I love the fact that @steemitblog and it's team are working daily to improve the blockchain and Steemit experience for its Millions of users.
