orv-privacy VS asmr

Sure - proposals have been made on how to do this. See for example https://github.com/PlasmaPower/orv-privacy.

Nano not having full privacy is a deliberate choice. Deliberate, because there are ways to implement privacy in Nano on the first layer. See for example CamoBanano or the perhaps even more comprehensive PlasmaPower proposal. Obviously neither of these have been implemented on the first layer of Nano by the Nano Foundation. The reason for this is that the Nano Foundation's goal is to have Nano as broadly adopted as possible. Given the hostility of many governments to full privacy cryptocurrencies, adding privacy does not seem like an ideal move. In that sense it's very simply a practical approach.

There's also CamoBanano on Banano though I have no idea what progress is like there, and the perhaps even more comprehensive PlasmaPower proposal.

And yes, there's area for improvement. PlasmaPower proposed a nano privacy model wherein balances, at least, are hidden.

Consensus initially seems to be an issue if Nano were to implement this, but a form of it could be made compatible with ORV such as implemented here or described here.

I think it's possible to reveal sums of commitments to determine voting weight. See this implementation: https://github.com/PlasmaPower/orv-privacy

Orv-privacy by Plasmapower would add amount privacy.

To be fair, not having privacy in Nano is a choice. We could clone it with privacy, see https://github.com/PlasmaPower/orv-privacy

The main issue is transaction malleability. BTC eliminates malleability through SeqWit. BCH did it through other means. According to u/kayabaNerve , who developed an atomic swap protocol, BCH<>XMR atomic swaps are possible, and there is now an active bounty with 1.25 XMR and 0.47 BCH for developing one.

I believe it was ASMR

Has anyone heard of ASMR (Atomic Swaps for Meros) or fiddled with it?

There is this, although I recall there being something “wrong” with it. Just can’t remember what: https://github.com/MerosCrypto/asmr

u/kayabaNerve created the first PoC of an atomic swap between Bitcoin and Monero and joined our team at its inception. Last month, kayaba shared on IRC that he decided to step back for personal reasons. We thank kayaba for his contributions and helpful ideas and wish him all the best! Hopefully, one day our paths will cross again :)

Hi, I've suggested similar ideas a few times, you can read up PlasmaPower's work on atomic swaps, similar mechanics. https://github.com/MerosCrypto/asmr
