What are seeds in the source code of bitcoin? https://github.com/bitcoin/bitcoin/blob/master/src/chainparams.cpp

starting from line 132, I see the function vSeeds.emplace_back("seed.bitcoin.") and next to them there are real full names. What do seeds do? What are these lines for? What is the meaning of those names? Can someone give a technical detail please?
In order for a bitcoin node to start connections with other nodes, it first needs a seed node. A seed node can be any node (listening) connected to the bitcoin network. Once the node has connected to the initial seed node, it can then retrieve information about other nodes in the network and start connections with those ones as well.

The names you are seeing in the source code are the URLs of some of the bitcoin core developers that host seed nodes. If you don't trust these crazy cypherpunks, you can actually specify your own seed node in your bitcoin.conf under the option seednode=&lt;your_seed_node&gt;
