Is Monero a fork of a scamcoin?

John Connor (VCASH def)  said that Monero stole his code, is that right?

Missed your post but great, thanks! I think the node got ddos'ed since within a few hours all bandwidth (250gb) got suddenly used. So I have to wait till the first of May for a bandwidth reset.

I will however double your contribution and have it run during May and June.
Thanks to Hueristic as well who is now in the process of taking over the node, yay!

And this one if you want to understand why john-connor the plagiarist and one of the few people in the history of open source to ever violate the MIT license has an agenda against Monero: Because I called him out on his scamming. Note, by the way, that most of the people quoted in that post documenting his ripping off of Bitcoin's code are not affiliated with Monero nor me in any way, I just quoted them.

If you have any questions about Monero and would like to learn about it from a credible, non-scammer, source, please stick around.

I was out for the meeting itself, but it was in my IRC log history. 

It seems this meeting was very Monero dev-centric.  Nearly all of it was discussion of pull request #'s without much substance of what those issues represented. 

I did a bit of research on a couple of them and wrote some notes - they're very light, though.  It sounds like there may be some better stuff (0mq, RingCT) discussed in the next dev meeting.

Watch-only wallet shows incorrect balance - it shows sum of all incoming transactions, if there were payments from the wallet balance will be wrong.

Yes, that's right. Spends have to be accounted for separately and subtracted. The function of watch wallets is to show incoming payments.

Question #1
Why is it only showing the incomming balance, and not the spended balance also?

Question #2
The usage of the viewkey option is quite, let's say, less good documentated. To clear some things up here a little bit, please advise me in the following schematic description

I have wallet "A" with the corresponding viewkey "B" from wallet "A"

If i want to check the balance of wallet "A" with the viewkey "B" i have to create a wallet "C" and have simplewallet running on wallet "C" with the command?

Code:

./simplewallet --generate-from-view-key "A":"B":viewonly

Am i getting something wrong here? I am sorry, but the documentation is not very expressive...

Sure, [1] The viewkey only shows which outputs belong to your address. However, it doesn't show if these outputs are subsequently spent. You need the spendkey/key_images for that. This allows, for instance, simplewallet to show you a balance, but not for a view wallet, since it only knows your viewkey.

[2] I know, but this goes back a long time. That is, in the beginning even the core-team members didn't properly understand the viewkey and what it was capable of. This was mostly caused due to the current core-team taking over the project.

The scheme you propose will only show the incoming transactions for wallet A. Thus, not a balance. For now, you would've to actually "open" wallet A to see the balance and outgoing transactions. In the foreseeable future though there will likely be some "hacks" around this. Also, Trezor will greatly mitigate this issue, see my original reddit comment:

Correct. However, (i) Trezor will greatly mitigate these issues because it is able to show you a balance whilst remaining safe (i.e. it's impossible for, for instance, malware to steal your funds) and (ii) there are some options to show outgoing transactions and thus a balance too, which were discussed in this thread:

https://np.reddit.com/r/Monero/comments/4dly99/lack_of_feature_to_easily_monitor_current_balance/
I'd also suggest to read this:

http://weuse.cash/2016/03/07/trezor-for-monero-first-impressions/

P.S. The protocol allows the audibility of a company via key images. That is, company A could hand over their key images and their viewkey for a given year and an audit company would perfectly be able to audit all the transactions and balances for that given year.

Hope this was sufficiently understandable.

SO i have to give out my walletaddress "A" and the viewkey "B" and the third party needs to open wallet "C" to execute this command or do they only beed "A" and "B"?
Why am i asking: I tried this and i was asked for a password. So is this password for wallet "A" or for a new generated wallet "C"?

I hope you guys can improve the viewkey option to show the actual balance of wallet"A" and also the spend ammounts from this wallet "A", then it could be used for bookkeeping against LEAs 

If you find the time, maybe you could update the moneropedia site in question for this matter, so it is understandable for doofies like i am

correct. The new password is for the new wallet C. This new wallet is unable to spend your money.

Agreed on the underlined. New improvements to simplewallet allow for individual bookkeeping, but not particularly audibility - i.e., you'd have to give someone your wallet files or something.

Though the point has been raised that bookkeeping doesn't need to be a fundamental property of a currency.

There is room for improvement for sure, but it is debatable whether it should be in the protocol or as a layered-on thing.

Just wanted to add that you can use the key_images for auditing/bookkeeping purposes.

"Small update on mobile apps: web management / easier set-up close to completion"

Relevant comments:

Question:

How does this affect smartphone wallets for Monero?

Answer:

So, I had previously created these two mobile wallets for Android / Windows 10 respectively:
https://github.com/ShenNoether/MiniNeroUniversal & https://github.com/ShenNoether/MiniNeroDroid

These rely on a server app running with your Monero installation, which is somewhat complicated to set-up (several command line steps). The web-app that this post references will run in conjunction with that server, and will have a web-interface to ease the set-up process). The web app should be able to most of the command line process with simply scanning a qr-code generated in the web-app with your phone app (this is the API-key tab).

Additionally, this version of the server should remove several dependencies which were making installation annoying on certain platforms, and add several alternative server languages (go, ruby, python, perl).

Caveat, that I am writing these in my spare time, and don't have a solid timeline for completion.

TLDR: The MiniNero web will make the setup of the above two phone wallets much easier. Additionally, MiniNero Web can be used as a simple, standalone wallet.

Small rectification:

All the notes you list after 805/806 are actually for 794. Wallet refresh speedups in 806 have no downside.

Logs will be posted as soon as possible as far as I know.

- Type 1 [1] governments (we rule you, but just tax you) are after your income. They tax that. How you spend your stuff isn't really relevant to them, as long as the recipients of your spending also account for their income, etc. Type 2 governments (we rule you, and you kowtow to our allegedly very large appendage every morning, peon) want all, because they fap at it. Monero can't cater to type 2, some may see that as a flaw.

- There is a patch somewhere on my github tree, that allows this, though relies on the sender to not be malicious (ie, if you spend from elsewhere, your watch wallet will see it, but a thief may choose to make a tx out that it will not see; so it's useful to keep track of your balance as you use your monero, but not to compulsively check whether someone brute forced your wallet).

- I have in my list of things to do a RPC to export a signed set of key images. I just added the ability to sign/verify an arbitrary message, which is a first step.

https://motherboard.vice.com/read/darpa-decentralized-blockchain-encryption-messaging-app

The Defense Advanced Research Projects Agency, better known as DARPA, is looking for a “secure messaging and transaction platform” that would use the standard encryption and security features of current messaging apps such as WhatsApp, Signal, or Ricochet, but also use a decentralized Blockchain-like backbone structure that would be more resilient to surveillance and cyberattacks.

DARPA’s goal is to have “a secure messaging system that can provide repudiation or deniability, perfect forward and backward secrecy, time to live/self delete for messages, one time eyes only messages, a decentralized infrastructure to be resilient to cyber-attacks, and ease of use for individuals in less than ideal situations,” according to a notice looking for proposals, which was recently posted on a government platform that offers federal research funds to small businesses.

In other words, as a security researcher put it, DARPA wants “a public wall anyone can monitor or post messages on, but only correct people can decrypt.”

Damn, DARPA getting all gangster wit' deh signalz.  (Chinese/Mexican/etc. mafias are well known for using publicly visible graffiti ciphers).

 

What would it take (IE how much would it cost) to port XDN's nifty messaging feature to XMR?

Are we far along the roadmap to do it without incurring too much technical debt and risking the need for a re-do?

I'm waiting for any excuse to donate to a worthy project in warptangent's name, to start a memorial fund.

What would it take (IE how much would it cost) to port XDN's nifty messaging feature to XMR?

While I've not tried it, I think it's mostly what we now have as a encrypted payment ids, except the size is increased to some large value, instead of being restricted to 64 bits. So pretty easy to add in theory, leaving just the UI fluff.

[smooth]

There are many ways one could implement messaging, but I don't favor storing p2p messages on the blockchain itself. Encrypted is even worse, in a way, since that can't possibly be of any benefit to anyone other than the specific recipient. (At least if you store bible verses or dick pics, there might be a few people who are interested in that.)

I would propose something like:

Create and submit a small transaction that pays a fee and includes a hash.

After the transaction is successfully mined, you may submit a message packet up to some maximum size (for example 32 KB) that matches the hash (assume the message is encrypted, but it wouldn't necessarily need to be) into the mempool, where it will be stored and relayed to peers. Once the transaction reaches a given depth in the chain (for example seven days; 5040 blocks), the hash expires and the message may no longer be submitted or relayed.

It is true that it is extremely difficult if not impossible to prevent use of the blockchain for storage of arbitrary data that does not benefit most of the people incurring the cost of the system, but providing a useful mechanism that does much the same thing in a less harmful manner is a good way to discourage it.

Possibly the lifetime and allowable size of the message could be a function of the fee paid, but there is no good way to set the fee, nor a good way to compensate the node operators for storing and forwarding it, so the suggestion of a fixed life and size is intended to limit the cost to something reasonably negligible.
