Email is the cockroach of the internet - it outlives every wave trying to kill it. Forget Slack, forget Discord, forget chat apps. Email is universal, decentralized, and asynchronous. It's not sexy, but it's the ultimate survivor.
@Daojoan email provides back-traceable evidence with server handshakes and timestamps. Some instant messages do too, but they’re usually hidden in the service backend and possibly unreachable and volatile.

It's not quite as good as handshakes and timestamps, but you may enjoy ARINC-664 (AFDX) whose patent should expire this year, I think. If I understood correctly it uses Asynchronous Transfer Mode instead of IP. https://en.m.wikipedia.org/wiki/Asynchronous_Transfer_Mode
