In the discussion started here @noahpierau discovered multiple places that state that Decred is influenced by PoA:

Some links even have a PoA subpage.

Do what is possible to update these resources with a correct statement regarding the relation with the PoA paper. Check this chat for background on Decred's relation with PoA.

If an article described in #4 is ready by then, ask to add a link to it to these resources.

https://en.wikipedia.org/wiki/Proof-of-stake as of 2019-01-11

Decred's hybrid proof-of-work and proof-of-stake, in which proof of stake is an extension dependent on the proof-of-work timestamping, based on the "proof of activity" proposal, which aims to solve the nothing-at-stake problem by having proof-of-work miners mining blocks and proof-of-stake acting as a second authentication mechanism.

Discussed here, suggested replacement:

Decred's consensus system is based on a proposal called memcoin2, which has much in common with and was developed independently of Proof-of-Activity.

Currently there are only two coins I was able to locate that use the hybrid proof of activity protocol. Decred is one and Espers is the other. Both use a variation on the proof of activity, where each block uses either PoW or PoS.

It forked bitcoin to enable a hybrid consensus system combining Proof-of-Work (PoW) and Proof-of-Stake (PoS) into the novel Proof-of-Activity (PoA).
