<DIV>I also need to argue for increasing the default block limit to the full 1MB
in the next release. We’re already hitting that limit in bursts of
transactions, which puts pressure on the average displayed in the below
graphs.</DIV>

we get to the maximum block size, the slower we grow the average block size

with average block size. Based on these graphs we can expect that hitting
1 million transactions per day will be impossible without raising the maximum
block size.</SPAN></FONT></DIV>

<DIV>Well, yes. Isn't that rather key to the issue? Whereas by simply
increasing the block size, SPV wallets don't care (same security and protocol as
before) and fully validating wallets can be updated with a very small code
change.</DIV>

<DIV>Let's say an old client makes a payment that only gets confirmed in an
