CryptoNote is the name of the cryptocurrency technology that Monero (and Aeon, and various others) is based on. CryptoNight is the name of the hash function that is used in the CryptoNote Proof-of-Work algorithm. CryptoNight-Lite is a modification of CryptoNight that uses half as much memory and fewer hash rounds, used in Aeon.

There is a command to lock coins when you make a transaction by RPC in simplewallet. I don't think it's implemented in the command line interface. It's the unlock_time parameter in the JSON RPC transfer, described in the source code here: https://github.com/monero-project/bitmonero/blob/eb1b87d2393f34caa9698bec23a4b78fa57da752/src/cryptonote_core/...

There is a lot of evidence connecting all of the companies mentioned in your question. There may be more connected companies that we are not yet aware of. From Wikipedia: The first Changelly prototype was created as a startup in 2013 by the enthusiastic team of MinerGate, a mining pool, that has one of the longest track record in the crypto industry. ...

There are two coins with that name. The first is called Dashcoin (DSH) and is a CryptoNote coin that was launched July 05, 2014 as an automated fork of Bytecoin (BCN) without the large premine. Dashcoin is a Next generation anonymous cryptocurrency and the first automatically mutating cryptocurrency created with CryptoNote technology. What does this ...

The answer to this question is long and any shortening doesn't do the question justice. This is an edited version of the excellent investigation of the bytecoin scam performed by user "rethink-your-strategy" on the bitcointalk forums written August 15, 2014. It is the best available account of the bytecoin scam, and covers the following areas from the ...

The 2 important things coming soon are ringCT and Kovri. In fact, ringCT is already coded into the last client software and the hard fork allowing such transactions will activate somewhere in January. RingCT is important because it's the last piece of the blockchain privacy puzzle: Currently, you can't know from where the funds came, thanks to ring ...

Reasonably, we have no real idea. This person or group is currently unknown just like Satoshi Nakamoto. The text in this Wikipedia article sums up some thoughts in the community about the creator(s) of CryptoNote: The author of the white paper went by the name Nicolas van Saberhagen, although like Satoshi Nakamoto (the author of the bitcoin white paper) ...

Much of the history of CryptoNote development is in dispute so I will stick to the facts. CryptoNote is a new cryptocurrency protocol using some of the Bitcoin principles but with new ideas and an entirely new codebase. The ring signature implementation described in the CryptoNote whitepaper, while unique, is based on established cryptographic principles ...

Quoting smooth, who is a member of the Monero core team and stepped in as Aeon lead developer a while ago: AEON is certainly targeting running a node on a smartphone, but I don't think it is possible to completely rule out Monero (someday) doing that too. As answered above by others the idea is to do experimental and perhaps even stupid things. Some ...

There are many other CryptoNote coins but their communities, usage, trading volumes and hashrate are much smaller than Monero. Here is a chronicalogical graphic of many of the coins and from where they were forked: https://en.wikipedia.org/wiki/CryptoNote#/media/File:Forks-tree-fixed.png You mentioned Boolberry, which like Aeon was an innovator in the area ...

To most of the community (see /r/monero, /r/aeon), Aeon is the "supportive younger brother" of Monero, and is viewed more so as a proving ground (i.e. for any relevant improvements, that are thus absorbed by Monero).

A lot of the other answers address some but not all of the questions. Is Monero intended to be a competitor to Bitcoin, or is the intent to develop technology that will improve Bitcoin? It is unknown whether Bitcoin will ever implement any of Monero's technologies, but from the outset, the cryptonote protocol (from which Monero has evolved) was made to ...

There's less than a couple dozen CN based currencies. See http://mapofcoins.com/bytecoin. Shadowcash tried to implement ring signatures on a Bitcoin code base. See https://shnoe.wordpress.com/2016/02/11/de-anonymizing-shadowcash-and-oz-coin/. To my knowledge, no non-CN coin uses Cryptonight. -- Oops, I misread that last question, see lethos3's answer to ...

Let's say you'll use two of your outputs, 12.34 XMR and 7.89 XMR and send 18.37 XMR to your recipient for a fee of 0.022 XMR and change of 1.838 XMR. If you use mixin of 4, you'll be creating two rings with 5 output keys contained in each. You'll pick a secret index between 1 and 5 for each ring, so let's say you picked 2 for the first and 4 for the second. ...

Aeon is a fork of Monero, created in June 2014 by an anonymous developer. It was abandoned soon after, and languished for a while with close to no hash rate. In October 2014, Monero developer smooth took over the fork and merged a handful of fixes and improvements from Monero, as well as changed the PoW and block time to be more friendly to smaller devices. ...

Is Dash based on CryptoNote or CoinJoin? DASH is a Bitcoin fork and uses a modified version of CoinJoin to perform private transactions. DASH its anonymity requires activity on the chain, i.e., you need other users to mix with. Therefore, it could take a long time before your DASH are fully "anonymized". Some older reports document mixing times of a few ...

Monero does not support multisig at the moment. It will at some point, probably not very long after RingCT is merged, since that work relies on RingCT building blocks. Cryptonote itself does not support multisig either, but Bytecoin (Cryptonote's first actual currency) does support it for mixin 0 (ie, without ring signatures involving other outputs). Monero'...

I think the answer is both Aside from the privacy advantage of not having worry about being identified as a ring signatures side chain user, Monero offers other advantages such as a hedge of having an alternative hashing algorithm to secure the network. In addition, next level advancements such as RingCT and Kovri will likely come much later in a ring ...

From my understanding, the problem with implementing ring signatures as a Bitcoin sidechain is that you would stand out like a sore thumb if you transfer normal Bitcoin into the ring-sig sidechain. The actual transactions on the sidechain might not be traceable but the transactions to/from said sidechain may well come under additional scrutiny (e.g. by ...

The Monero community almost unanimously voted against merged mining choosing instead to stand on its own and avoid indirectly supporting another CryptoNote coin, BCN that was 80% premined.. Actually voting is closed now as soon as nearly nobody wants merge mining in BMR In hindsight measured by network hashrate, the Monero community made a wise decision....

Section 4.4 of CN white-paper describes this. With the ring signature, all the keys used are equivalent, so you can't say which one is the actual signer. The signature can be checked against any of the public keys used in the ring. Let's define our one-time keys as P = xG Where P is the public key, x the private key, and G the EC basepoint. If we let the ...

G is the base point of the Ed25519 elliptic curve. The x coordinate is not written explicitly because it can be found back using the y coordinate, the sign of x and the equation of the curve (x is positive for G). Points on the Ed25519 curve are represented by 32 bytes. These 32 bytes are in fact the little-endian representation of a 256-bit number. bits 0 ...

Diffie-Hellman key exchange is a key negotiation mechanism to agree on a common key between two parties using an insecure channel. How can you do a key exchange between two values both available to you? Both values are not available to the party you want to communicate with. If you were to transmit both values, then someone could intercept them and know the ...

Including it as a sidechain would not make Bitcoin transactions very private as you'd still know which coins were used in the sidechain. Ring signatures would need to be baked into the Bitcoin protocol, and become mandatory for Bitcoin to enjoy the same level of privacy and the chances of this happening are probably extremely slim. This would be the same ...

big busts in btc from blockchain analysis Another market of comparable size (is there one? idk) accepting monero BTC-e adding monero (I don't know all the exchanges but they're the only usd to monero exchange I think have the cajones. lol) gui and ringct won't bring as much adoption I don't think....but then again, if the current pool of bitcoin traders ...

Botnets do not have magical ability to affect Monero more than any other hash source. As other PoW based currencies, Monero is vulnerable to 51% attacks, and any adversary who is able to sustainably mine faster than the rest of the network will be able to slowly increase the cumulative difficulty of an attack chain, and thus override a "legitimate" chain. ...

Although it wasn't clear to the reviewers at the time, the constants are standard ed25519 constants from DJB et al. You can read about it here, especially section "Choice of curve" starting on the bottom of page 7.

Ring signatures are a group of cryptographic signatures with at least one real participant, but no way to tell which in the group is the real one as they all appear valid When sending a transaction, you select some random transaction outputs on the blockchain and mix those with your own coins Mixing enforced across the network, meaning active participation ...
