I first thought that's fake news, but it seems that you really can pay now with XMR at a few select Spar supermarkets in Switzerland that participate in a trial:

"Just payed my organic Cacao at Spar with Monero (XMR)."

<t​rasherdk:monero.social> With a payment processor as middleman.

Yeah, isn't there always some fly in the soup? :)

Hoping for Spar to put a QR code with a Monero address at their cash counters is a bit optimistic ...

You can choose to fully boycott this of course :)

"Frankencoin", lol for real?

<m​onerobull:matrix.org> they also make the dEUR vik invested in

<m​onerobull:matrix.org> ive had a look but got kind of sussed out when i saw they gave themselves the ability to mint new dEUR with frankencoin governance tokens as collateral

<g​ingeropolous:monero.social> theres that txpool

<g​ingeropolous:monero.social> though its prolly the 10 min block as opposed to increased chain activity

Cool

<a​pplepearshop:matrix.org> What are the current estimated timeframes for FCMP++ and Serai? Is it still 2027 for both projects to reach their mainnet launch and be usable within wallets or frontends?

FCMP++ 2026

public testnet Q4 2025

<a​pplepearshop:matrix.org> 👏

no idea about serai

<a​pplepearshop:matrix.org> Do you think that hardware wallets, such as Trezor, will support the upgrade? I'm wondering how it will function, and I'm concerned about FCMP++ being computationally expensive

<a​pplepearshop:matrix.org> For hardware wallets

before testnet there will be an alpha stressnet next moth and the main stressnet in July

<a​pplepearshop:matrix.org> What does stressnet mean?

AIUI it will not be computationally expensive for HW wallets

stressnet is run with a high volumne of txs to see if anything breaks

a stressnet was run last year which highlighted some issues which were then addressed

<a​pplepearshop:matrix.org> Also, correct me if I'm wrong. But how can FCMP++ protect against poisoned outputs? Can't chain analysis just compare the state of the blockchain before a new output is created and after it's created, and then track new outputs in the list?

applepearshop there is nowwhere to track it to. every traction action after its creation will have it as an input. there's no way to tell where it goes

<o​frnxmr:xmr.mx> The transaction where it is created though?

<o​frnxmr:xmr.mx> i guess knowing the true spend doesnt matter if it can't be linked to the outputs that precedes it

FCMP++ protects against poisoned outputs, but chain analysis can just compare the state of the blockchain before a new output is created and after it's created. The latter does not prevent the former.

Whole chain proofs mean that when you spend an output, whether it is a "poisoned" one or not, an observer has no idea which output gets spent.

The output you spend was created prior to the spending, so looking at chain state before and after that output was created does not give you info on when it will be spent later on.
