	21 …	+This is not true. Consider git: Each branch could be considered as source of
	22 …	+truth (or rather "point of truth").
	23 …	+Branches may depend on eachother, branches may be merged. Branches may _not_
	24 …	+depend on eachother (git can have multiple "orphan" branches) and may _not_ be
	25 …	+merged. Still, they are points of truth.
	26 …	+With p2p systems in a decentralized environment, this is true as well.
	27 …	+There might never be the _one_ version which is currently the point of truth,
	28 …	+but as long as versions of the system can be merged, this is not a problem.
22	29 …
	30 …	+Events in such a system can even be sorted chronologically via
	31 …	+[vector clocks](https://en.wikipedia.org/wiki/Vector_clock)
	32 …	+where each key is the unique peer hash.
	33 …	+
	34 …	+There exists a technology which brings data types to the table which can exist
	35 …	+in a p2p system without ever needing a single source of truth. These types are
	36 …	+named [CRDT](https://en.wikipedia.org/wiki/Conflict-free_replicated_data_type)s.
