I run a number of high speed nodes and while I don't have historical logs handy over time, I've noticed a drop from about %5-%10 SPV clients at any one time to closer to %1 (Matt: you have a few TB of logs saved don't you?) Also, as I mentioned, just look at the popularity of wallets such as Mycelium that are not adopting bloom filters, but going with SPV verification of block headers w/ lookup servers. Anyway, look at the analogous implementation of NODE_GETUTXO's, which helpfully has provided the infrastructure for wallets that need bloom filters to find appropriate nodes to connect too - we certainely aren't seeing any shortages of nodes for those wallets to use. --=20 'peter'[:-1]@petertodd.org 00000000000000000402fe6fb9ad613c93e12bddfc6ec02a2bd92f002050594d --nFreZHaLTZJo0R7j Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature -----BEGIN PGP SIGNATURE----- iQGrBAEBCACVBQJV1sASXhSAAAAAABUAQGJsb2NraGFzaEBiaXRjb2luLm9yZzAw MDAwMDAwMDAwMDAwMDAwNDAyZmU2ZmI5YWQ2MTNjOTNlMTJiZGRmYzZlYzAyYTJi ZDkyZjAwMjA1MDU5NGQvFIAAAAAAFQARcGthLWFkZHJlc3NAZ251cGcub3JncGV0 ZUBwZXRlcnRvZC5vcmcACgkQwIXyHOf0udwT3Af9FIQ6Hf+hvPO7h0fYWRqzrhPS 0Ty1xjwFUB3bIWH25z3TETkdtWUBTZKgOwx4HFd5m7TycPak69IQAGS5+CxwhrEg oNNZ4EGw0QhfquAbv8yVhL7pHn1UnCbhYx/eQTxqKlszCIS95ZLiypVlpX+O4W4j rpa/xDzVqcxVuZZy8szEGz3ldSd6BrvRMeDRDF1/AZGL3VmD06ZcEltPI6MAZLp0 F4s2IVowTtDApqXoI/KmC+d8yhQLKXXvir5Tc8TIN954zbo+iiJLF5z1Q6/c54qU GFsAid99tNJJ/N9JAgkY44vNOEK5zgpUXk+wSotQwEQPjF7GjhOI4418saGp9A== =OMhl -----END PGP SIGNATURE----- --nFreZHaLTZJo0R7j--
