So tell us how is your "vision" of 10,000 big beefy full nodes with SPV peers any different from the Electrum model? These days Electrum clients have block headers and verify that transactions have merkle paths to the block headers. The only difference I see is that SPV uses bloom filtering and Electrum can query by transaction. But Mike wants to add querying by transaction to full nodes anyway, and one of the purported advantages of this UTXO proof stuff is that you can query servers for UTXO's by address, so I see no difference at all. A patch to do bloom filtering on Electrum would be amusing to me. Here you have Peter talking about clever ways to actually get decentralization by having SPV peers donate back to the network with spare bandwidth, like relaying blocks, not to mention his partial UTXO set ideas, and you completely ignore that. But I guess that would raise ugly questions when people realize they can't now contribute back to Bitcoin, because the blocksize is a gigabyte of microtransactions... It may also raise ugly questions with regulators that may find the idea of "full node == data chokepoint == regulatory chokepoint" an attractive notion. Why are there not any competent people other than Peter who really have the guts to bring up these proposals? I've little luck getting proof-of-concepts built for money anyway. Maybe we just have a darth of smart competent people in this space. You do a good job of signaling your priorities Gavin. The payment protocol includes no notion that you may want to pay anyone but a SSL certified merchant. Yes I know the crypto can be upgraded, but it says volumes that you pushed for that first, without even the slightest token effort to allow individuals to participate in any way. Sad given you have made things *less* secure because there is no safe way to get money *into* my wallet with the payment protocol, but could have been. Tell me, when my decentralization pull-req is voted on, which way are you planning on voting? -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQEcBAEBCAAGBQJSEYg/AAoJEEWCsU4mNhiPQBIH/A2cef0NDzu72CY0+N1HdPO+ fdixwncAg1ok6YdJj5WALjHbkhJ+QRVEZoRr6rHPxxxTywI+HiPN1oaopIrq3StP bNpvouaWXLyw6xHMrMYefVOluHNZg3lu1akLdGuYA7rDHLwP/RhlF1FFzXSxKFsp ANcw4WW7U5r5nfBHYc/a9xo8S6THI7Nv2NDW6WaRQO4X9sbSKSdwanoe75CLsRzE E2cPNvwG4WA/MUgkl3Ao6dMsEPPa8dJK98LaS4BE/m9iFWQiV8t35/FQ0GAFQoJo PQUs8aAWiI0caAxI0vddxKQ+YlwPw2m1QH6h19wUO7+KLKOtxMFmWoDu/OLdTRM= =IfkA -----END PGP SIGNATURE----- ------------------------------------------------------------------------------ Get 100% visibility into Java/.NET code with AppDynamics Lite!
