"Small update on mobile apps: web management / easier set-up close to completion"By NobleSir / Shen Noether https://imgur.com/a/Hifdbhttps://www.reddit.com/r/Monero/comments/4gcl4u/small_update_on_mobile_apps_web_management_easier/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/MiniNeroDroidThese 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.

(snipped) 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.

3. Afaik the new versioning capability that will be introduced with SegWit, basically hands the power to Blockstream to drive forks any time they want to. Again this is another game theory discussion which I don't wish to elaborate on at this time. Note Monero's periodic forks as a protocol also seems to a form of centralized control. One can argue that miners can vote, but it is fairly impossible to stop the political clout of the lead developers especially when that control is hardwired into the protocol. Satoshi's design was that it should be nearly impossible to hard fork, because that is the only way you truly have decentralization.
Regarding [3], if miners/exchanges/merchants don't agree with the lead developers they can just remain on an old(er) version. I said it is a complex game theory discussion. Seems you want to force me to have that discussion when I said I am busy on other more urgent priorities. Because I can't just leave your afaics incorrect assumption there unrefuted. You can't retain an older version, because soon the new features will become intertwined in everything and soon you won't be able to function in the network. The complexity of failure modes with an older version are beyond the scope of the discussion I want to have now. That will be a technical discussion. Just remember what happened the last time I got into a technical discussion with gmaxwell on Ogg streaming format indexing, a topic that he thought he was more expert on (and he should have been since he was the co-inventor of one of the Ogg codecs). I admit my statement was perhaps a bit too black and white. Furthermore, I do not want to provoke (force you into) a discussion.

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? ./simplewallet --generate-from-view-key "A":"B":viewonly
Am i getting something wrong here? I am sorry, but the documentation is not very expressive... I think this sufficiently answers your question(s): https://www.reddit.com/r/Monero/comments/4gakjp/maam_13_monero_ask_anything_monday/d2fysebIf not, just ask again. Thank's for the link, that's an awful lot to read for a simple question, i tried to read it out of there but unfortunately not managed to do so... Would you be so kind to explain it in a way, as i tried to in the above example, simplified so i can understand this too? (Maybe update that point at moneropedia too) Thanks in advance 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: Hope this was sufficiently understandable.

Segregated Witness is just another way to centralize mining. I will explain that in the future when I am ready.
... but that is a small price to pay in order to increase the blocksize from 1 MB to an effective 1.6 MB accomplish - Malleability Fixes
- Linear scaling of sighash operations
- Signing of input values
- Increased security for multisig via pay-to-script-hash (P2SH)
- Script versioning
- Reducing UTXO growth
- Compact fraud proofs
ftfy The technically-challenged will conflate features with don't require Segregated Witness with an argument for why we need Segregated Witness. Segwit is an elegant way for Bitcoin to gain those benefits. I never said segwit was the only way, but it's good enough and it's happening. Other coins (like Monero) enjoyed second/late mover advantages by being designed for those features from the beginning. Frankly I haven't yet studied SegWit in great detail, because I will wait until they have finished it, so I am not losing time studying a moving target. I have no influence on the Bitcoin community's decisions, thus studying it now is of no significant advantage in the holistic priorities. Conceptually I understand that SegWit enables outsourcing validation and retains hashes of the validated data on the block chain. Afaics, this is centralizing for at least three reasons: 1. Those with preferential access/propagation to validators can earn more with the same hashrate by mining on the correct block slightly sooner. Over time this moves ROI and thus hashrate concentration to those who have these political connections. However, this is not much different than the same effect that can exist now where miners with significant hashrate (even a cooperating set of them) can validate their block announcements sooner than the rest of the network. Afaik, the salient worsening due to SegWit is that validation concentration can now be political, not only by hashrate concentration, so it amplifies the vectors towards centralization. 2. Afaik, SegWit relies on trust enforced by voluntary fraud proofs to insure that the validation is correct for each hash on the block chain. Afaics, the game theory around these voluntary fraud proofs drives more centralization. But this is not something I want to detail now. It is a complex discussion and I am busy on more urgent priorities. 3. Afaik the new versioning capability that will be introduced with SegWit, basically hands the power to Blockstream to drive forks any time they want to. Again this is another game theory discussion which I don't wish to elaborate on at this time. Note Monero's periodic forks as a protocol also seems to a form of centralized control.

Other coins (like Monero) enjoyed second/late mover advantages by being designed for those features from the beginning. I heard that the SegWit will be implemented in a few weeks according to the bitcoin core road map. So the price could rise. Make that a few months, the pull request just came in last week if I recall correctly. It needs to be reviewed thorougly first. Also, bear in mind that it only gets activated if it reaches a 95% treshold of miners running the code.

XMR / Monero broken crypto:I think chainradar are using all the 0 mixin transactions from exchanges and pools in order to guess - the things in https://lab.getmonero.org/pubs/MRL-0004.pdf. I tried some transactions with mixing 7 and 5 between my wallets and they are successfully guessing most of them. This issue is already addressed in the MRL-0004 and we knew that, but it's scary seeing it in chainradar. Everybody should stop using mixing of 0 until this is enforced in the protocol - including pools and exchanges. I suppose some mixings between your own wallets with high mixing should resolve the issue for now. Trollfest incoming . This was refuted at the time by: https://github.com/fluffypony/chainradar-checkerI tested it against 19 transactions, some mixin 4 and some mixin 20 (excluding my own signature, so mixin 5 and 21 according to ChainRadar).
For these transactions none of them were completely compromised by ChainRadar, and ChainRadar got 0 out of 157 guesses correct. If you are going to claim such a thing, please properly check it wasn't bogus/FUD.
It's bad crypto alright. Monero users were transacting "anonymously" for a year only to discover later that they could be trivially deanonymized because those in charge hadn't fixed a "hole" in the system from the start. Erroneous as well, like I've stated above and others pointed out as well.
Also, what is the point of opening these kind of threads? It will end in mud-throwing anyway. Ironically it already started in the first few posts here.
