The Monero Research Lab is a team of voluntary researchers, scientists and academics that did analyse Monero and its predecessor CryptoNote in the past, explaining both past attacks and possible privacy issues in the current network. Their research is mostly funded by donations from the Monero community and is publicly available.
In the following segment I ...
StringCT is an upgrade to the existing RingCT MLSAG ring signatures. It was initially informally known as RuffCT in honor of Tim Ruffing, who is one of the authors of the paper (soon to be published) from which this new type of ring signature originates. The initials of all of the authors of the paper are RTRS, so RTRS Ring CT == STRRRingCT == StringCT. ...
In short, someone managed to exploit a bug in the code, which produced a block that couldn't be validated by the nodes, there's a full analysis of the attack here, https://lab.getmonero.org/pubs/MRL-0002.pdf
Fluffy explained it well, so I'll just paste his abbreviated comment from here: https://www.reddit.com/r/Monero/comments/30jp2n/...
The daily variance appears to be limited to about 10% of the hashrate. Two possible explanations:
A system administrator mines Monero at night when computers would otherwise be idle
A system administrator mines Monero during the day while having physical control of the computers.
Replace system administrator for anyone with control over a large group of ...
In addition to the (very likely) reasons given by Big Things, there is also the distinct possibility that something in the difficulty adjustment algorithm is causing this. It could be the way we're cutting off outliers, for instance. One of the MRL projects is to investigate the difficulty adjustment algorithm precisely for this reason:)
There have been some conversations about the need for producing professional looking Monero videos. Some videos have been produced from volunteers within the Monero community and from organizers or participants of events where a Monero developer has spoken but more are needed. Here is some existing audio and visual content produced by volunteers:
RingCT will make multisig easier to implement, as the planned multisig system relies on RingtCT building blocks.
Contrary to the Bytecoin multisig, Monero's will not be limited to mixin 0 transactions (in fact, Monero banned mixin 0 transactions in the general case since it is harmful to privacy, so cannot even use that system as it is).
Aeon does not have a minimum mixin by design. Transactions with mixin 0 can be very small and inexpensive. This is by design. According to smooth If usage increases there is a built in system to limit growth of <2 mixin transactions, thereby preventing the low mixin generated cascading privacy reduction described by the Monero Research Lab as follows:
I am not sure how the connection was established, but Surae Noether was paid by the then core-team to review the CryptoNote whitepaper (and thus the CryptoNote protocol), and some of the code of Bytecoin, where Monero forked from. From the review of the CryptoNote whitepaper we can read the following:
For full disclosure, I was hired by the Monero (XMR) ...
Monero Research Lab Publications MRL-0001 to MRL-0005 have been published.
MRL-0006 - Difficulty Adjustment Algorithms in Cryptocurrency Protocols
have been started.
According to fluffypony
The difficulty research that Surae was working on is quite extensive, but incomplete.
EDIT: as of November 17th, it appears MRL-0006 will be renamed MRL-0007.
The behavior in the transaction you linked is a new one. It did not exist at the time MRL-0004 was written.
Now, if you make a transaction now including your 0.00111111 output, it will appear as is as an input to that transaction (and you may have to send it with mixin 0, unless there are two other outputs of that size on the blockchain already). However, ...
In theory multisig was "simple" to implement in Monero, at least the way the Cryptonote whitepaper describes. It had never been implemented though.
There is ongoing research to implement multisig on top of RingCT and you can find a draft MRL here.
Is there any talk of "hiring" a community representative to create video blogs/ pod casts?
There is plenty of talk, though the best talk is what is coming out of you. And while hiring is possible, the best efforts come from those who, for better or worse turn of phrase, believe. There's no other way to put it. Well, perhaps there is. But its passion thats ...
This is not a protocol level issue, but a network one: someone monitoring the network can still connect transactions and the IP addresses of the nodes that first broadcasted them; and if you just run Monero's client out of the box there is no built-in protection against that!
Run your full node through TORSOCKS following the instructions ...
Yes absolutely. It wasn't designed in isolation, it was a group effort with members of the Core Team and the MRL involved. Since Shen did the bulk of the work, and was responsible for much of the innovative cryptography, he is the primary author on the research bulletin. You'll notice, however, that Adam Mackenzie and the Monero Core Team are also listed as ...
It appears the world will learn of Monero largely the same way it learned of Bitcoin, as a currency for use on illegal Darknet marketplaces.
Wired posted an article about 16 hours ago, containing the following:
This week, the dark web market site AlphaBay started accepting Monero, a cryptocurrency with an even bigger emphasis on anonymity than Bitcoin. ...
Someone found a bug in a tree hash function, and managed to exploit it, resulting in an unresolvable fork in the chain.
There is a full explanation from Tacotime: https://bitcointalk.org/index.php?topic=583449.msg8677607#msg8677607
Github user divbit responded to the issue on Github here. To quote:
Hi, the paper states that it is a sketch of a proof (mainly it's a sketch because the things are no more efficient than the Borromean ones which are mentioned could be used on a previous page, and possibly less efficient according to the Borromean paper, in some cases (e.g. higher bases ...
At the moment very few people are more than peripherally aware of Monero's existence. Nothing will focus people's attention more than the recent rise in the market cap. Though it may be wrong headed logic, when people hear of something going up 300% they often think - 'oh I should get on board that train' , or at least 'I need to find out more about this'
An output's public key uniquely identifies an output .
A ring signature takes N outputs, one of them being the one that's actually spent, and makes a signature that can be verified, such that:
one of the outputs in this ring is spent
all the outputs in this ring have equal probability of being the one being spent
Now, the scenario in MRL-0004 is more ...
What are the background and qualifications of those assigned to do the peer review? Do we know the identity of "reviewer A" and "reviewer C" that are cited in the open review?
As with most academic journals, the reviewers are selected by the editor(s) of the journal. Reviewers are chosen based on their qualifications as they relate to the content of the ...
Based on this comment from fluffypony it appears that MRL-007 was skipped and does not (currently) exist.
@kenshi84 any chance you could do a formal write-up and submit it to the Monero Research Lab repo for us to publish? It would go as MRL-0006, and the current WIP that is MRL-0006 would be moved out to 7 or something.
@kenshi84 confirmed a willingness ...
According to the bottom of this CoinTelegraph article:
The Jaxx team clarified that they halted work on Monero due to recent
protocol changes that caused difficulties, and because the integration
had gone significantly over time and budget, and was therefore
hindering development for the 1.2 release.
There was a large divide in the community, and I ...
I don't believe it was due to a lack of API support since documentation is available. I've been able to interact with the daemon and monero-wallet-rpc using cURL from the command line and with PHP. You can see available documentation here:
Here's someting about elliptic curve cryptography that helped me understand it. Also, there's a site studying security features of various elliptic curves. For other things (such as ring signatures), I'm hoping that someone else can provide useful references.
