MTP is defined as the median timestamp of the last 11 blocks.
BIP 9 determines a block height based on MTP. Every 2016 blocks BIP 9 says "Does this next block have a MTP past start/timeout time?"

Why does the threshold apply to the MUST_SIGNAL phase in revised BIP 8 (lot=true)? Why doesn...
nickler answered this on IRC.
In a mixed network, the rules can become active, but in two separate chains because lot=true nodes will reject blocks from the lot=false chain which doesn't require 100% …

Why is there no forced signaling during the LOCKED_IN phase of BIP 8(LOT=true)?
The state transition diagram of BIP 8 is here.
The specific change you refer to was made in this BIP PR by AJ Towns. Once we move into the LOCKED_IN phase of BIP 8 the soft fork is definitely going to …

Should block height or MTP or a mixture of both be used in a soft fork activation mechanism?
Using block heights for the start and timeout parameters has the advantage of giving miners a known number of signaling periods. Loss of hashpower doesn't reduce the number of retarget periods availab …

Every soft fork or consensus change involves a (very small) non-zero risk of a network split. That risk is considerably lower for a soft fork than say a hard fork (where all nodes need to upgrade). Th …
