I haven't seed a bootstrap style copy of a pruned blockchain and not sure if one exists. I'm not sure how feasible it is to share a copy of the pruned chain as it will also depend on the number of MB that each person allots for raw block & undo data. I suppose it might be possible to bootstrap this if both the copies where using the same pruning configuration but I'm not 100% sure.

I would not mind one thats pruned at default 550 , even if its months old, it would still be better than trying to make one myself from scratch

Isn't a pruned node personalised to your wallet? I got the impression that it needed to keep your unspent historic transactions, as well as a number of the latest blocks?

No. The only data pertaining to your wallet is stored in the wallet.dat file. The pruned blockchain is simply the block files and a database so that Bitcoin Core knows what has been pruned and what has been verified so far. The blockchain data and the wallet data are completely separate.

So if anyone is running a pruned node, please upload a copy of the files.

Just to make sure you are aware of what you are doing: If you download the pre verified blockchain data from someone else, you have to trust them to not have modified the data.
