Given the success of the previous MAAMs (see here), let's keep this rolling.

The principle is simple: ask anything you'd like to know about Monero, especially the dumb questions that you've been keeping for you every other days, may the community clarify it all!

Finally, credits to binaryFate for starting the concept!

So I am using a rasberry pi 3 b+ to run a monero cli full node. I was having trouble getting my external drive to play nice with non sudo users, the only way i could rw was with sudo so I am running monerod as sudo to point --data-dir at my external mount. Is this considered unsafe? I have a firewall on the pi, this is a local networked node, and i am not port forwarding with my router.

Second question, are there any hardening guides / best practices for monero nodes? (feel free to suggest non-monero specific hardening if appropriate)

I’m assuming Monero will never integrate a trusted SNARK. Perhaps a good enough MPC trusted SNARK?

But if not then what would it be, STARKS or some other zero-knowledge proof?

I’m obviously not a cryptographer so please understand I’m aware I sound inexperienced and may be making little sense

We have a new build script for the Linux GUI using cmake + docker. This is the first time we are using it so I thought I would ask on Reddit for testers before we use it for a release.

Here are the advantages we have with the new build script:

• Easy to build static binaries
• Ubuntu 16.04 or higher support (previously we only supported Ubuntu 18.04 or higher)
• Saves us time and trouble when doing a release

Please test if the GUI starts correctly or if you notice anything else.

• Download link (Linux): https://gui.xmr.pm/files/monero-gui-linux-x64-v0.16.0.2.tar.bz2
• Signed hash: https://gui.xmr.pm/files/hashes-v0.16.0.2.txt

If there are no problems found here we will release a new GUI version on all platforms soon. Thank you :)

I'm reading over the repo stuff here: https://github.com/monero-ecosystem/monero-javascript

This looks like an amazing platform for building wallet functionality into various apps. But I do have one question. Will the WebAssembly stuff run on iOS/Android? I've been thinking about building a wallet app for mobile, mainly to teach myself React Native.

Has anyone tried using this library for mobile development? Any experiences to share?

Please stay on topic: this post is only for comments discussing the uncertainties, shortcomings, and concerns some may have about Monero.

NOT the positive aspects of it.

Discussion can relate to the technology itself or economics.

Talk about community and price is not wanted, but some discussion about it maybe allowed if it relates well.

Be as respectful and nice as possible. This discussion has potential to be more emotionally charged as it may bring up issues that are extremely upsetting: many people are not only financially but emotionally invested in the ideas and tools around Monero.

It's better to keep it calm then to stir the pot, so don't talk down to people, insult them for spelling/grammar, personal insults, etc. This should only be calm rational discussion about the technical and economic aspects of Monero.

How it works:

Post your concerns about Monero in reply to this main post.

If you can address these concerns, or add further details to them - reply to that comment. This will make it easily sortable

Upvote the comments that are the most valid criticisms of it that have few or no real honest solutions/answers to them.

The comment that mentions the biggest problems of Monero should have the most karma.

As a community, as developers, we need to know about them. Even if they make us feel bad, we got to upvote them.

So I'm wondering when nodes validate transactions in a transparent ledger, they check if an address has certain funds and therefore can send as much and validate that the transaction is signed with their private key.

On the other hand, can you explain how transactions are validated in Monero? How nodes can validate if a certain address has how much amount if both addresses and amounts are hidden on the blockchain? Rangeproofs? Still is confusing to me how nodes can know which addresses have what, since looking as outside observer you can't know to which address funds are sent

Thanks!!

Dear community,

I’d like to know your opinion, is it time to start working on the full client for mobile platforms?

At the beginning of Monero, in 2014, that wouldn’t be a question. But today’s newest mobile devices may have enough storage, computational power and bandwidth to enjoy all the features of a desktop client (including storing whole blockchain and even mining)

Please share your thoughts

That is all.

I sent a nickel to a friend and we can't see it in our transaction history and it's been a few days now, is there a limit?

I wonder why Monero is providing SHA256 hashes, instead of pgp .asc files?

Thats the way Electrum is doing it - and I find it far more convenient to quickly check if a file can be trusted and was actually signed by a certain Monero dev.

Any reason for the Monero way?

I've just been doing some testing with Cake Wallet and noticed something interesting. Cake Wallet actually blocked me from sending XMR until it was finished syncing my wallet data.

Is this strictly necessary? Let's say I was going to whip out my phone and buy something in a shop with XMR. If I only do an XMR transaction once a week or once a month, it might take a while for Cake to sync my wallet data. That's quite a pain, especially if I already know that my balance is correct (I know I haven't sent any funds from another device, etc).

Is waiting for the sync process strictly necessary? Do I need to wait for it in order to be able to create the ring signature or something? Or would it be possible to allow creating send txs before the sync has finished so that it would be possible to do quick payments while out and about?
