How is BitCoins truly desentralized?

[Rudde]

Hello,

I was trying to build a truly decentralized application. But i fast ran into problems. Where noone know what peers to speak too, in BitTorrent they have some form of centralization where you have DHT or trackers feeding the clients with the peers they are suppose to connect to, and that makes the system vulnerable, take down the trackers your decentralized system don't know whom too speak with and nothing get done. So I tough to myself how does BitCoin handle things like this? Is there a more centralized system giving peers the IP's? If not, how does it then work? Since broadcasting don't work on the open net, and would be stupid. And if you do have these "trackers" who owns them? How are they stored in the BitCoin Core code? Whom provide them and who can provide them?

Thanks for any reply!

Best regards,
Rudde.

There are several well known dns records maintained by the core devs that provide an up-to-date list of seed nodes. If those dns records are taken down, there is a hard coded list of nodes embedded in the code, updated with each release.

Will these nodes act as a DNS record or just nodes? Or will everybody rely on these nodes if they are taken down? And how many DNS records are there? And whom are in control of them?

In the absence of the DNS seeds, you can simply ask someone for the address of a node and connect to it.  Once connected, your node will learn thousands of addresses.

The DNS seeds are just a convenience.
