Unfortunate. What makes them not work out? DHT torrents seem pretty popular. > More importantly, I think it's very important that the process of > offering up more storage not take any more steps.

I only mean if it is possible in an easy way to integrate the BitTorrent technology into Bitcoin in an automatic fashion. Yes part of that may have to be finding a way to re-use the existing port for instance. > We already have to worry about nodes finding each other just for basic > operation.

Sure I guess my concern is more how do you find the specific part of the chian you need without some structure to the network? Although I guess it may be enough to just add that structure or depend on just walking the nodes advertising themselves until you find what you want. We can build this stuff incrementally I'll agree. It won't be the case that one in a thousand nodes serve up the part of the chain you need overnight. So many I am over engineering the solution with BitTorrent. > Using Bitcoin to bootstrap the Bittorrent DHT would probably make it > more reliable, but then again it might cause commercial services that > are in the business of poisoning the bittorrent DHT to target the > Bitcoin network. Good point. Sadly one that may apply to the Tor network too in the future. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) iQEcBAEBCAAGBQJRfe1LAAoJEEWCsU4mNhiPuDgIAM1zz+ohlHgz37RgToQhInRc 1tv4Fnb6uGWyb4+U6UpK24LlXMFvOJsLm2czgbBc1Iz4z4wvb1m5IGw0ubJuV4mT GPUJhM4sNqfeKZlSWRw4Gia6Vk1jTkue+uVYvZn2vBS4SS6vYhYCC3zXIITyb2mp 7CVjcM84bTHKxIaMW1rIgmVJmfslsFdeNOp/cDVvkNl9+WvzWPeJ32BkT522p+pT AcPVFMsEJirYrXYi8HwdtGSeiG+mv0IemTAObJNPRrpw3x04ja6qecqzM51AkQ4t hPems5ShXM9FyDKFQNmtoC6ULpbd3CBBjsiQj0pp55epy6UC0eiUIXP8L9v0giM= =AOj8 -----END PGP SIGNATURE----- ------------------------------------------------------------------------------ Try New Relic Now & We'll Send You this Cool Shirt New Relic is the only SaaS-based application performance monitoring service that delivers powerful full stack analytics.
