State of this repository

What is the state of this repository?

The last commit seems two years old, but at the same time readme mentions RingCT.

Is this implementation compatible with the current Monero network?

Readme also mentions https://github.com/ShenNoether/RingCT-Python repository, but that is no longer existent. Can anyone point me to a new location?

Did you look at this repository?

https://github.com/monero-project/research-lab

I am not sure if that particular code is also there, but regardless, there's a lot of demo code in that repository.

P.S. I strongly encourage you to use our IRC channels as well (#monero-dev and #monero-research-lab in particular).

@prusnak There are a few things that won't match the live implementation, notably:

1. ASNL has been replaced with Borromean (and sometime soon-ish that'll probably be replaced/used side-by-side with bulletproofs)
2. MLSAGs in live are always 2 rows, rather than #inputs+1 rows, due to column linkability. This means there is one MLSAG per input and a new "pseudoOut" is introduced for txs with more than one input (see: https://github.com/monero-project/monero/blob/master/src/ringct/rctSigs.cpp#L670)
3. There is a minor change to encrypt the mask and amount with the recipient's viewkey, rather than the destination pubkey.

The rest looks pretty close from a brief perusal, but of course this is not authoritative.

Edit: I'm talking about this file in particular: https://github.com/monero-project/mininero/blob/master/RingCT2.py
