Aha! Just figured it out! I was using version 28.1 today which is giving me those XOR'ed files. Last week I had 27.2, so that makes sense. Just reinstalled 27.2 and now my.dat files are good to go. Thanks for the help!

But why am I seeing this only now? All those blk*.dat files I grabbed last week are totally readable and have the magic bytes at the start. It’s not like the blocks were in perfect order, but still worth noting. What's…

So, I just set up Bitcoin Core, but I got some confusion with the blk00000.dat files... I downloaded a bunch last week and they look fine, like starting with f9beb4d9... but the one I got today is weird, doesn't start…
