The descending triangle is normally a bearish pattern. The question now is will the bears follow through?

1 day candle just closed as a green hammer on bitcoinwisdom. That has been a bullish reversal signal multiple times in the past. I think it was rpietila that first pointed that out. About 5000 of the 13500 wall at .00300 got taken out by a single sell. There were about 630 BTC in buy orders that dropped to 407 this afternoon. Volume is very low. I think the question is still open, are we in an uptrend or a downtrend? I think there is btc on the sidelines waiting to find out how this descending triangle plays out.

Notice something we haven't seen in a long time, resistance.

It is a tough call.

Descending triangles are normally considered a bearish pattern more likely to break out on the downside, on the other hand they can break out on the upside and when they do it can be sharp and sudden. I find the changes in the order book also very interesting. Most of the buy orders that have been removed are from below 0.002. This would indicate that these buyers have given up on purchasing XMR below 0.002, have removed their bids in the hope of driving the price down or both. I see also two possible "Swords of Damocles" hanging over the bears in the short term. 1) The database being released. 2) Dash breaking 0.01 on the downside.

This setup is starting to look like a sharp move is coming, the question remains which way.

i wouldnt say DRM in general is bad. DRM is bad when you don't own all the keys (up to the root of course).
imho (in theory) i'd prefer a locked down pc (tpm and drm) where i own all keys because i control what software is able to run: no more viruses, no more spyware....

atm it seems any pc/smartphone is insecure anyway - even without tpm/drm.

If the owner of the device owns all the keys up to root, then this is not DRM. It is simply a well secured device or computer. The whole point of DRM is to attempt to secure content where the owner of the computer or device is treated as the adversary.

Edit: It is very easy to secure a computer. Use GNU/Linux and encrypt the home partition or the whole drive. Then do not run as root for day to day operations.

I never want to see this happen.  Living in NSA America is bad enough.  Liberty and Privacy first.

If one is using propriety DRM infected, locked down, systems it will happen. if one is not then it will not happen. The biggest threat to freedom coming out of the USA is not the NSA, it is the MPAA and any organization that uses DRM to "protect" its "premium" content. Understanding the real threat is the first step to dealing with it.

A very good of thumb. If your device supports DRM at the operating system level in any way then any and all information on said device is accessible to the NSA.  

Edit: Android is a perfect example. If one roots the device, a must to protect one's Liberty and Privacy, then the DRM on the device no longer "protects" the content providers. One simply cannot expect a computer or device to have two masters. The choice is DRM or Liberty and Privacy but not both.

How do we force people to use key escrow?

Leaving aside the technical questions, the real question is: how do you force anyone to do this stuff? Escrow requires breaking changes to most encryption protocols; it's costly as hell; and it introduces many new security concerns. Moreover, laws outlawing end-to-end encryption software seem destined to run afoul of the First Amendment.

I'm not a lawyer, so don't take my speculation too seriously -- but it seems intuitive to me that any potential legislation will be targeted at service providers, not software vendors or OSS developers. Thus the real leverage for mandating key escrow will apply to the Facebooks and Apples of the world. Your third-party PGP and OTR clients will be left alone, for the tiny percentage of the population who uses these tools.

Unfortunately, even small app developers are increasingly running their own back-end servers these days (e.g., Whisper Systems and Silent Circle) so this is less reassuring than it sounds.

If source code is protected speech under the US First Amendment then using Free LIbre Open Source Software solutions, and staying well away from propriety software from companies like Microsoft and Apple is the answer. For server based products use only zero knowledge solutions. Furthermore one avoids using a "provider"  large or small, that has propriety systems that can be compromised. I fail to see the problem.

ArticMine is right, Monero being the electronic cash of the future needs the 1 min confirmation time. 30 secs would be good but theres no reason to change imo. When tail emission kicks in and blocks are 0.3 XMR, the 1 min confirmation time will make even more sense.

Sure, but whether or not Monero needs it matters less than whether or not it's currently possible (without sacrifice).

Ultimately, I believe point-of-sale transactions will eventually be handled off-chain, which makes the case for 1 minute block time somewhat irrelevant.

OK here is another scenario. You fund an account to make an off chain point of sale transaction. A 5 min wait time is acceptable while a 30 min wait time is not. There is a tradeoff here and we need to find the optimal solution.

Ideally yes. But the issue of orphan blocks raised by smooth is very valid. My take is getting a handle on the number of orphan blocks by monitoring the current network at various points may provide valuable data that can be used to make an informed decision. There is a tradeoff here.

I think you are trying to win an argument rather than really listening to what I'm saying. What im arguing is incontrovertible but i don't think you are really listening enough to know specifically what it is that i am arguing.

Oh well its not that big of a deal anyway. As far as i understand it fluffypony is only wanting to increase the block time to 2 minutes or something like that. For all i know without having more information that could very easily be an improvement to the security of monaro. In fact i would bet it is since FP is a really smart guy.

Anyway I'm done arguing.

You're right that it's a "sliding" scale, but I think you're being a bit ridiculous to suggest that any significant number of users would stop using a crypto that ups it's block target from 1 minute to 2 or 3 or 4.

I think smooth's point is that a transaction is either fast enough for real time, point-of-sale purchases, or it isn't. Beyond that, the differences don't mean much.

For those who haven't seen it, Vitalik Buterin wrote an interesting article on what it would take to achieve ultra fast block times in a PoW currency: https://blog.ethereum.org/2014/07/11/toward-a-12-second-block-time/

There are a host of scenarios where a 1 min block time can be very advantageous over a two min block time. We must keep in mind that were are dealing with the outlier event of say a 5 min confirmation vs a 10 min confirmation here also.  XMR.TO is a perfect case. With a 1 min blocktime on the XMR side there is a very high probability of meeting the 15 min transaction time set by XBT processors, with a 2 min blocktime on the XMR side this is no longer the case since there is a significant chance of an outlier 10 -12 min XMR confirmation that not allow for the 15min overall time limit.

Restaurant and bars are another example. Ever being out with a group of say 10 people and 8 of them pay by debit card or credit card? By the time the debit machine reaches the last person easily 10 min or more has elapsed. XMR or XBT transactions can be processed in parallel rather than in series for example by scanning a QR code printed on the bill with a smartphone. In this scenario XMR with a 1 min blocktime would beat debit while XBT with a 10 min blocktime would not. The target here is an average wait of 5 min with debit.

There may well be a very good case to increase the blocktime in XMR to say 2min; however if this is done it should be done promptly before more services that are dependent upon the 1 min blocktime are built on top of the network. We simply cannot predict what will be built on top of XMR. By the way XMR with 1 min blocktime is getting close to the theoretical limit, and I suspect that Vitalik's 12 sec confirmation could easily run afoul of the law of special relativity.

Edit: I will take a look at Vitalik's paper.

If I understand this correctly one can count the number of
Code:

events on bitmonero.log vs the number of blocks that have elapsed to get measure of the orphan rate that one sees. If a representative sample of nodes monitor this then one should be able to get a handle on the orphan rate.

I am trying to find some statistics on the current orphan rate for Monero.
1674  Alternate cryptocurrencies / Speculation (Altcoins) / Re: [XMR] Monero Speculation on: April 13, 2015, 12:24:09 AM
...

If you look at the analysis by Meni Rosenfeld and more recent work by others, the optimum appears the be the smallest time that gives close to zero orphans even in a decentralized network (not just a few pools with fast connections to each other). That's probably something like 5-10 minutes (10 minutes was close when Bitcoin was designed and latency seems to have roughly dropped by half since). This assumes not using modified protocols such as "GHOST" which address the orphaning issue but create or don't address enough other problems that they aren't generally viewed as a desirable upgrade, yet.


I am taking a look at the article. It does raise the question of where we expect network latency to go in the future, so a confirmation time that is sub optimal today could become optimal in the future.
1675  Alternate cryptocurrencies / Speculation (Altcoins) / Re: [XMR] Monero Speculation on: April 13, 2015, 12:10:32 AM
I really like Monero blocks being 1 min, I dont understand what it means negatively for mining but for the end user it means its fast! That being said I would not care if it was changed to a more "optimal" 2 or 3 min (with emission accordingly).

The perceived speed is just psychological since a 1 minute confirmation is worth half as much as a 2 minute confirmation for establishing consensus.

The key is that the faster confirmation of 1 min allows for a finer grade of security in the confirmation of transactions. So with 1 minute block a merchant can choose between 0min 0 (confirmations) 1 min (1 confirmation 2 min (2 confirmations0 etc while with a two minute block the merchant only has the choice of 0min (0 confirmations)  2 min (1 confirmation (Edit:close to) equivalent to the previous 2 confirmations) etc. This can be critical for certain applications such as XMR.TO. The trade off is orphan blocks, which depends to a large degree on network speed and latency.

When - what date or what blockheight - would the tail emission kick in ?  

It is hard to know the exact date/block because it depends on penalties. Each block's reward is a function of the actual number of coins created so far.

It will kick in whenever the reward according to the formula would be less than 0.3 XMR (approx 0.9% annually), which is expected some time around year 8.


Why 0.9%?


Edit: I guess what I'm asking is, what is the actual formula for the tail emission, the resultant inflation year over year and why was that amount chosen?

The formula is "0.3"

The amount was chosen based on being a round number within and close to the <1% inflation maintenance reward specified in the ANN OP.



I found this on github

Code:
+#define FINAL_SUBSIDY_PER_MINUTE ((uint64_t)300000000000) // 3 * pow(10, 11)

Does this mean a constant block reward = 0.3XMR ?

Yes. that's what it means, unless the block time target is changed higher or lower than one minute, in which case all rewards including that one will be scaled accordingly. That is the base reward, but there will still be penalties for having blocks that are >median so the actual reward may be lower (in fact this is one of several reasons it is necessary to have a maintenance reward).



So the tail emission is now defined in the code and protected by the proof of work. I was concerned about this but alas no more concern. Excellent!!

I do not see a 0.0028 to 0.0045 trading range

The trading range is derived from the price:volume scatter chart, which indicates that half of XMR volume ever traded was traded in that range.

0.0028 I see as a very strong support, then resistance and now support again, so I don't have an issue with the lower part of the trading range. I just do not see anything that special at 0.0045 in the charts. My take is that 0.0050 - 0.0058 range is a more likely place for the bears to make a stand. Furthermore the drop in XBT/USD, XBT/EUR etc since last summer would also tend to bias the trading range upwards.
1678  Alternate cryptocurrencies / Speculation (Altcoins) / Re: [XMR] Monero Speculation on: April 11, 2015, 10:53:55 PM


I do not see a 0.0028 to 0.0045 trading range, rather I see an upwards trendline channel with very strong support at 0.0028 with two scenarios. 1) Continuation of the trendline channel with a test of 0.0050 and a possible test of 0.0058. A break of the upward trendline would be very bullish and could lead to a test of 0.010. 2) My second choice is a breakdown of the bottom trendline and possibly a break below 0.0028.  
1679  Alternate cryptocurrencies / Altcoin Discussion / Re: XMR vs DRK on: April 11, 2015, 03:51:41 AM
Edit: The recommendations in MRL004 implicitly assume a reasonable distribution, not a premine of over 80% of the emission. They apply to Monero but not to Bytecoin.

That's not exactly right, the recommendations assume a distribution of usage that is reasonable. Even a starting concentration of say 80% will still eventually burn out, but it will take a very long time. On the other hand if someone controls both 80% of the coins and also conducts 80% of the transactions (say using their own exchange off in Estonia or something), then it won't work.



So if the attacker controlling 80% of the coins also conducts 80% of the transactions among wallets under the attacker's control then the attack will work.
1680  Bitcoin / Bitcoin Discussion / Re: Has anyone successfully evaded collections agencies by exchanging fiat into BTC? on: April 11, 2015, 02:43:28 AM
IANAL. In these situations legal advice is strongly recommended.

The critical difference here is that a wage garnishment is typically limited to 20%-30% of the take home pay while a bank account garnishment can go up to 100% of the funds on deposit. So if the employer pays in Bitcoin or Cash the creditors are limited to the 20%-30%; however if the employer deposits the wage into a bank the creditors can get 100% of the wages by a bank account garnishment. The other thing to keep in mind is that collection agencies typically go after the easy assets and that one of the purposes of collection calls is to try to get the debtor to reveal information about his or her assets or sources of income.
 
For this reason anyone who is afraid of creditors would avoid the banking system and stick to cash and crypto-currency unless they go into bankruptcy or some kind of creditor proposal. There is a reason for the popularity of cheque cashing stores.

There is also the question of practicality it is way cheaper for a creditor to get a bank account garnishment than to get the courts to force a debtor to reveal a Bitcoin private key.

One of the advantages of having some XBT in this kind of situation is that the XBT can be used to pay for legal advice, particularly as is often the case when collection agencies step on the wrong side of the law.


Edit: The choice between Bitcoin and a bank account in this situation could easily be between the creditors getting 30% of take home pay or the creditors getting 100% of take home pay.
