this cuts the max memo in half. The memo is now 1/4 the size of a single share, and costs 25% more per gas (10 gas/byte vs 8 gas/ blob byte)

I think we can explore how the memo is currently used. And limit the number to the minimum necessary. also, In celestia people can exchange messages directly in the blobs instead of the memo field.

How is this used by the Cosmos SDK? Got a link to docs maybe?

blocks per year is used to determine the rate of change for inflation (we currently have the max inflation rate change set to 0, so this value shouldn't be important unless we ever change it)
