Does blockchain distribution work like in bittorrent?

[User500]

Hello,

Does the blockchain/block distribution in bitcoin core work like in bittorrent?
More precisley: Does the downloading client start to upload to other clients even if the blockchain download from
the origin client isn't complete?

Yes. Also, the blockchain is not downloaded from one client of course (for security and practical reasons).

Sorry that I aks again: Yes means in this case "yes it does upload meanwhile downloading"?

You can ask a node for a block even while that node is downloading.

Most nodes have (almost) the entire chain anyway, so it isn't that big a deal.  You are unlikely to connect to a node that has only just joined the network.
