What are the variations between the varied MTPs in Bitcoin?
I believe there are 3 totally different MTPs (median time previous) in Bitcoin (although this can be incorrect). David Harding stated on IRC that there was a MTP in Bitcoin v0.1 (Satoshi’s first launch). There’s additionally MTP as utilized in BIP 9 after which there may be MTP as outlined in BIP 113.
If certainly there are 3 totally different MTPs in Bitcoin, why? What was the motivation?
