Hai there. So I found this out in about a week or two ago in our PS4, so I don't know if this actually has been fixed or not. Anyway, so that time my sis and I are trying to experiment what will happen on the moon by me blowing up a TNT to demonstrate an asteroid. Unfortunately, my sis was blown up (she was in Adventure mode while I was in Creative). The death message said "Player was blown up by Block of TNT" instead of "Player was blown up by AnotherPlayer" . It was weird, so I hit the web and nothing said anything about that weird death message, not even the Minecraft Wiki.

Steps to reproduce:
1. Ask a friend to stand near a TNT
2. Ignite a TNT (You can use anything, from Flint and Steel to Redstone Block)
3. Blow your friend up

Expected results: Death Message should have said "Player was blown up by AnotherPlayer"
Observed results: Death Message said "Player was blown up by Block of TNT"

Does this death message actually existed and I knew nothing about it? Thanks for reading.

Kind regards, PinkRuby and her sis
