I'm not even talking about using the\nDHT trackers, but using old fashioned HTTP based trackers. The fact that\neach bitcoin client would contact the tracker would make it very hard for an\nattacker to get bootstrapping clients to exclusively connect to his\ncompromised clients. I would say that using a tracker such as OpenBittorrent\nprovides the same advantages as using an IRC channel.\n\nOn Mon, Jun 13, 2011 at 11:09 AM, Jeff Garzik \u003cjgarzik at exmulti.com\u003e wrote:\n\n\u003e On Mon, Jun 13, 2011 at 4:55 AM, Christian Decker\n\u003e \u003cdecker.christian at gmail.com\u003e wrote:\n\u003e \u003e We have quite a few bootstrapping mechanisms, starting with the overly\n\u003e \u003e complex (IMHO) IRC bootstrapping, which is often suspected as\n\u003e bot-activity.\n\u003e \u003e Then we have a few hardcoded nodes and some fallback nodes.
