Re: Blocks are [not] full. What's the plan?

Just do this:

For example lets look at this recent block:
https://blockchain.info/block-index/443364/0000000000000003b90c99433d07078d5498910442489383f18e250db0a843e2

301 tx and 480 KB. If the block message was changed to be just tx hashes the block message would drop from 480 KB to ~10 KB or a 98% reduction in size.

then you do not need to do this:

we should schedule a change to the max block size to be 10mB in a year or two

and we can easily support more TPS than PayPal.
