That'd be 7 bytes of nonce in the block header, which is
72,057,594,037,927,936 ~ 72 petahashes = 72,000 terahashes
So: the changes for version 2 blocks would be has height in the
coinbase, and has a 1-byte version number with a 3-byte extranonce.
I don't understand why more nonce bits
My point is that stuffing nonces into whatever spaces we can find to
eke out a bit more scalability in pools seems like a very short term
fix with potentially very long term consequences.
Although it may sound harsh, if your pool is struggling to keep up
with calculating merkle roots (which is
I think it would be great to have more nonce space with less merkle
calculation; keeping track of all possible versions of a block already
takes real RAM, real computation. Being able to change one bit in the
header and send out a new block for checking would ease our pool server
work by a real
