The Sunflower Farmers blockchain game DDoSes the Polygon blockchain for several days

Sunflower Farm, a play-to-earn farming game on the Polygon network, contributed to massive slowdowns and a spike in gas fees on the Polygon blockchain. Heavy bot usage and a game design where practically every action (including saving the game, using a tool, harvesting something) required a blockchain transaction flooded the Polygon blockchain with more traffic than it could handle, and spiked gas fees for a given transaction from around 30 gwei up to more than 1000. This event casts some doubt on Polygon's claims it can handle up to 65,000 transactions per second — in reality it averages about 85 transactions per second and so presumably should have had a lot of wiggle room for even a pretty major increase in transactions.
