no no no
simple shit like :
1) making sure the gossip network actually does make every peer on average use 503Bytes to get everyone to hear about a 500Byte msg.
2) communicate new blocks by listing all the TX ID's in that block instead of in full.
3) has SOME trusted centralized nodes dedicated to allowing new nodes to sync fast ( probably don't even need to trust them using some fancy PGP or something)
4) and yes some SPV, and maybe different types of nodes, simi-full node, full node, super node, minner node.
wtv it takes.
It's disheartening to see how some people want to sacrifice Bitcoin's uniqueness just because they hope that more txs on blockchain will somehow help in their
get rich quick scheme. Nothing unexpected, though...
Truth is, there might be optimizations in the relay protocol, but I doubt they are as significant in the grand scheme of things.
nothing i proposed there " sacrifice Bitcoin's uniqueness ".
there is a relay network which implements #2 and gets blocks to miners that connect to this network and configure there software to accept new blocks in this way (header + list of TX ID") get there blocks 250X faster.
clearly there are significant optimizations to be had.
whats disheartening is seeing how poeple are so afraid of the tiniest changes, bitcoin development grinds to a halt.
