zeitgeist VS kagome

I received a similar question in the last AMA. I'm going to copy and paste my answer from there.. ...there are quite a few projects which are a bit different or are C2C focused, even aside from the ones you mentioned (e.g. Subsocial). For example,Totem Accounting's KAPEX parachain which allows for on-chain recorded accounting. Robonomics allows you to control real-world hardware via its parachain (I've taken a few pictures of different nebulae and minted NFTs from them by controlling a telescope via Robonomics Network). Zeitgeist is developing prediction markets. Of course, if you still see a hole in the market, we'd be happy if you want to build it. We have several different funding sources to help you do so.

I met someone from Zeitgeist, a company that builds a para-chain in the Polkadot ecosystem for prediction markets.

As far as we are aware, Zeitgeist and Basilisk are still shipping quality code. We've looked into Zeitgeist latest update (20 hours ago) and it seems that they are getting ready for reward distributions due to the inclusion of the rewards pallet version 0.6.0

Kagome, the C++ version of the Polkadot Host, has released version 0.9.2, including such features as BEEFY consensus and using C++20. https://github.com/qdrvm/kagome/releases/tag/v0.9.2

There are a few other implementations of the Polkadot Host available. ChainSafe is currently developing a Go version of the Polkadot Host, Gossamer, and Soramitsu is creating a C++ version, Kagome.
