Note that the majority of hashing power is using Matt Corallo's block relay network, something I confirmed the other day through my mining contacts. Interestingly, the miners that aren't using it include some of the largest pools; I haven't yet gotten an answer as to what their rational for not using it was exactly. Importantly, this does mean that block propagation is probably fairly close to optimal already, modulo major changes to the consensus protocol; IBLT won't improve the situation much, if any. It's also notable that we're already having issues with miners turning validation off as a way to lower their latency; I've been asked myself about the possibility of creating an "SPV miner" that skips validation while new blocks are propagating to shave off time and builds directly off of block headers corresponding to blocks with unknown contents. --=20 'peter'[:-1]@petertodd.org 00000000000000000327487b689490b73f9d336b3008f82114fd3ada336bcac0 --0OAP2g/MAC+5xKAE Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature -----BEGIN PGP SIGNATURE----- iQGrBAEBCACVBQJVZ1VEXhSAAAAAABUAQGJsb2NraGFzaEBiaXRjb2luLm9yZzAw MDAwMDAwMDAwMDAwMDAwMzI3NDg3YjY4OTQ5MGI3M2Y5ZDMzNmIzMDA4ZjgyMTE0 ZmQzYWRhMzM2YmNhYzAvFIAAAAAAFQARcGthLWFkZHJlc3NAZ251cGcub3JncGV0 ZUBwZXRlcnRvZC5vcmcACgkQwIXyHOf0udwDtwf/Y/V4odt7j+QnHBwOozDz8ImX 44UT0yv4UZVjynBr8+pZCH3S6w5qa4IaZNNJjZ7Z51F2ya1Gcf8K/C93NMUuO6+F MPgH6ldqMPUSZifaoRewvr8ihay/gNyBkFIkOViK4wUUSWnuwOzzTaRKpkTWptCo I6bOUSfZNkdw9XcLLxlULX7cnJPRhD3zmn5oCeP6cSEersIOSG7+dgue1U2VDW5X 8Q3iI7zzX5OJyw3xPbzL5CaObqqCaWp6BjjLwSddHzzdrP6jF8KCo2+ylYQinWbn qd/cQtpfjf8KvDCYU/+gA7NsoSIuoe/3k7wBfUXSsuhmuSeRLcb5zgtv9qjR0w== =3MpU -----END PGP SIGNATURE----- --0OAP2g/MAC+5xKAE--
