I'm curious why block times were moved from 9 seconds to 12 seconds from testnet to mainnet and why are TPS 75 when (if i'm not mistaken) testnet was upwards of 350 tps to as high as 1,000 tps and Atlantis was claiming around 500 TPS prior to testnet / mainnet? What is the plan going forward to scale that? Are you guys planning to do a write up explaining what you hoped for, what you're currently at, and what you plan to do to improve the network scalability in the future or the avenues you're considering for scalability in the future?
