You can find the\n\u003e latest version of this document at\n\u003e https://github.com/TheBlueMatt/bips/blob/master/bip-TODO.mediawiki.\n\nThanks Matt!\n\nI've been testing this for a couple weeks (in various forms).  I've\nbeen getting over 96% reduction in block-bytes sent. I don't have a\ngood metric for it, but bandwidth spikes are greatly reduced. The\nlargest blocktxn message I've seen on a node that has been up for at\nleast a day is 475736 bytes. 94% of the blocks less than 100kb must be\nsent in total.\n\nIn the opportunistic mode my measurements are showing 73% of blocks\ntransferred with 0.5 RTT even without prediction, 87% if up to 4\nadditional transactions are predicted, and 91% for 30 transactions (my\nrough estimate for the 10k maximum prediction suggested in the BIP."}
