and then later
this "problem" seems to have a very simple solution to me, and i haven't seen anybody else talk about it, so i thought i'd share it here. basically the transactions should be assembled outsize of the great firewall of china - somewhere with fast internet - then only the block header need be transmitted into china for mining. infact the block header need only be transmitted once per mined block, and the 32 byte merkle root can be updated and transmitted more frequently to the miners in china as new transactions are added to the block (prior to the mining operation being completed of course).
then, once the miner discovers the nonce that mines the block they can transmit this back out and broadcast the block to the network. transmitting 32 bytes past the great firewall has to be easy. and of course it never changes regardless of block size.
has anybody else considered this already? is there any reason this is not already happening?
I suggest you stop taking anything Mike Hearn says seriously. He's got his own agendas & will say anything to try & manipulate people right now.
