No you can't. Programs can only look at blocks in the past, not the future and there is no "until a block is found" operation.

Check Ethereum Alarm Clock

"An ethereum contract that facilitates scheduling function calls for a specified block in the future."

But you'd have to cap the number of your operations, true.

The Ethereum alarm clock doesn't work that way. Your program can't "loop and wait for the next block" the way AlexGR described. For one thing, the alarm clock events are a part of a separate transaction and only one transaction (logically) executes at a time.

2602  Alternate cryptocurrencies / Altcoin Discussion / Re: The Ethereum Paradox on: March 15, 2016, 11:29:49 AM
The primary reason that smart contracts are basically useless, is because a block chain can't form a consensus about anything external, except for signatures transactions that are authorized by public key cryptography to modify block chain state.

I'm sure they have some not very widespread uses but the "virtual computer" concept is definitely useless, so far.

Quote
It can only form a consensus about block chain state transformation with the clock period being blocks and the longest chain rule.

Still, if the clock period is block, and, code-wise, can be used as a ...clock, then there is a clock.

So, say, I write a program which says "I add 42 to 42 to 42 to 42 ...until next block is found".

No you can't. Programs can only look at blocks in the past, not the future and there is no "until a block is found" operation. More practically if there were, a program that tried to do a long-running loop like that would likely run out of gas (which results in state rollback and loss of gas). Programs have to be small and simple.

Ok thanks for that info, we are not far off.
Will there be any updates that need to be installed on the users end?

There will be a point release soon with some important bug fixes (mentioned in the dev-meeting and a few days back on IRC as well). Furthermore, you should be running any 0.9.x version (preferably 0.9.2 when it's out).


The fork is close at hand.  Any one heard or read any new news around this? 

I'll ask on IRC. However, the only thing necessary is for miners to be on 0.9.x in advance of the fork.

Users do as well.

If you are running anything older, get upgraded now.
2604  Alternate cryptocurrencies / Altcoin Discussion / Re: The Ethereum Paradox on: March 15, 2016, 10:34:56 AM
I don't understand what you mean by censoring code. There is a virtual machine and the virtual machine instructions are all deterministic. There is no instruction that could produce a random value.

No, because you can't check time either, so you can't write that program!

Hmmm...

a) That sounds extremely crippled

I guess that is debatable. It isn't (marketing hype about "world computer" aside) intended to run all general programs. It is intended to run programs useful for smart contracts.

Quote
b) That sounds extremely broken if the result is ...forking (I'm not sure that it can keep things deterministic when there are tens if not hundreds of possible triggers for indirectly randomizing things).

Well it is risky, but there's a lot of effort behind making sure those triggers don't exist, multiple security reviews, etc. So far no one has found a way to do it, at least not in the wild.

2605  Alternate cryptocurrencies / Altcoin Discussion / Re: The Ethereum Paradox on: March 15, 2016, 10:17:25 AM
@AlexGR, everything in Ethereum is deterministic. There are no operations that have different results on different nodes. At least if everything works properly. If not then it can fork the chain.

Aha, that's closer to the answer I was hoping for. Thanks.

Ok, so is it censoring code that it doesn't like or something?

I don't understand what you mean by censoring code. There is a virtual machine and the virtual machine instructions are all deterministic. There is no instruction that could produce a random value.

Now let's do something else. I'm adding a constant number (not random), let's say the number 42, for 1 entire second. Everything is given / predetermined: a) The number to add (42) and b) how long I want it to perform what I want (1000 msecs). The result though is different because one pc will have made 500 million additions, another will have made 10 billion additions, depending their cpu power.

Can I fork the network now? Cheesy

No, because you can't check time either, so you can't write that program!

if Ethereum is a distributed computing platform

It isn't; it's a replicated/redundant computing platform.

If I make a simple program to get a random number from 1 to 100, or base my program on a randomizer, how can that be repeated in every single node? Shouldn't they give different outputs? How can that be validated?

Let's say I want to make a betting app, based on the random rolling of dice. How can that work?

Can't you grab it out from latest block hash?

You can, if you want the result to be able to be manipulated by miners.

Can you make a view-key from the mnemonic seeds,easy?

Yes, load the mnemonic seed into simplewallet and ask for the view key.

Obviously do this with due care for your security since the mnemonic seed itself (but not the view key) will allow spending the coins

It isn't; it's a replicated/redundant computing platform.

Fault-tolerant is a good term I think. Perhaps that helps define its (possible) utility too.

What if there are calculations that are so important and valuable that they can't be left to any one system or even a redundant cluster of system under any sort of common control? That might be worth something, but I don't think any of the currently-envisioned Ethereum use cases are that.

Have you even once considered the gross excess of "shady pump and dumps" is enabled by the toxic, hostile environment for truly original, worthwhile projects that might need some good programmers to get paid?

There is nothing wrong with getting paid and there are many good models for doing that. The unregulated nontransparent ICO model is not one of them.

I agree with cryptohunter on the ICO model being deeply flawed (even if it does "work" in a few exceptional cases -- that does not disprove the general rule) but I don't agree that banner ads can fix it.

Quote from: cryptohunter
Half ICO half POW not so bad.

Yeah its only half bad Smiley

To be clear PoW can be bad. The ultra-fast PoW coins where a bunch of insiders and pumpers rent hash and rape it for a day or a week does nothing to remove manipulation. Slow and steady PoW distribution over years is much harder to game, but arguably that too could be gamed by long-term monopolization (if it turns out that Bitcoin's largely-monopolized mining is not a temporary condition).

But surely POW if following a fair release set of rules.

1. advertised release time and date
2. low block reward at the start
3. diff adjusts quickly
4. long term mining

surely this is

1. far harder to game
2. far easier to see if it is being gamed.


ICO is total mask for what happens behind the scenes. With no rules at all.

POW is not perfect but it is 99% better than unregulated non transparent ICO with little advertisement and over in a flash.

Not too mention the other kind of ICO where they just run off 100% with the funds.

Some ICO try harder than others by a long way to ensure some kind of half decent distribution at the start.

No disagreement.

Do you vouch for him? I certainly don't. I've stated two things previously in other posts:

I don't know him personally but his posts are generally an accurate technical analysis. Like everyone else he occasionally gets things wrong, but more right than wrong (and usually corrects his errors later -- we are all learning about this stuff after all). I've seen nothing to suggest you have any idea what you are talking about. Maybe you do, but I haven't seen it.
2612  Alternate cryptocurrencies / Speculation (Altcoins) / Re: [XMR] Monero Speculation on: March 15, 2016, 12:32:12 AM
Monero sounds too stupid to begin with. Not even mentioning its completely flawed architecture. You got a piece of the altcoin pump pie and now you will once again fade into oblivion. Get a job.

Meh... what is flawed in the architecture... hate people that throw around words but do not even give an argument. And the sound of something is subjective you donīt like it ... others do.

I was going to delete the likely troll post/replies but the above bold is actually a reasonable question. We'll see if Sukovsky responds, otherwise, let's try to ignore the trolling and not reply to it.

Is the plan still to wait for LMDB before asking Poloniex to list Aeon?

How is development going smooth? We all know you have a busy schedule and appreciate your efforts!

There are still issues with LMDB being worked out in monero (can follow the commits, pull requests, and issues on the Monero repo: https://github.com/monero-project/bitmonero)

The main thing before doing a merge here is that it become a bit more stable.

StinkyLover I challenge right now to a live video debate.

Put up or shut up.

Yes or no?
LOOL! You are a joker. Get lost.

So readers now you know he shut up because he knows in a live video debate, his lies will be revealed.
Whatever you say, baby doll. Keep those long posts coming. I'm still waiting for your contribution to the industry. Then we'll ALL see the truth (or lies).

He's contributed a hell of a lot more than you have have afaict.

Nick Szabo is also primarily a writer in this space, among others (including Vitalik BTW). That counts as contribution. What is yours?

Announced ahead of time... release data and time known well in advance.
winrar wallets fully downloadable with pass protection..so all unrar at the same time
very fast diff change
low block rewards scaling upwards.

Monero and AEON had #1 (announced) and #3 (good diff adjustment) and had compiled Windows builds. Once you have that I don't think the others really matter much because there is no huge edge to being a little earlier than someone else. Maybe you get an extra block or two in the first few minutes, but not millions of coins or anything crazy.

The only real problem coin on his list is probably Litecoin, since the old-school 2016/4x difficulty adjustment was a bit of an instamine (2-3% IIRC). Not sure about DOGE.
2617  Alternate cryptocurrencies / Speculation (Altcoins) / Re: [XMR] Monero Speculation on: March 14, 2016, 05:16:26 AM
So here is a question: why did BCX choose to fuck with XMR?  I remember it all like it was yesterday, but I'm thinking it must have been at least a year ago.

I'm just not plugged in enough to know if he has done anything similar since, but wouldn't one think that BCX vs. ETH is a real possibility with all the dooshiness afoot?


BCX also went after LTC. https://bitcointalk.org/index.php?topic=96186.msg1060442#msg1060442. Here is some history on LTC https://bitcointalk.org/index.php?topic=47417.0 Now what do LTC and XMR have in common? They are both solid FLOSS projects with no premine. Now what else do LTC and XMR have in common? Well LTC was forked from Tenebrix and XMR was forked from Bytecoin. For that matter what do Tenebrix, Bytecoin and Ethereum have in common?. Premine. Yes I know that Bytecoin supporters claim is that it is a ninjamine rather than a premine but the evidence does indicate premine. http://https://bitcointalk.org/index.php?topic=740112.0

My theory is that if someone forks Ethereum into a clean FLOSS project with no premine there is a good chance BCX would try to go after the fork. As for BCX going after Ethereum itself it just does not fit the pattern.

Interesting theory. Another thing LTC and XMR have in common is quickly eclipsing the original premine coins. This hasn't happened with Ethereum despite there being a few non-premined (I think) forks.

Following the money and asking who has something to gain, a possible answer would be pump groups. Premine coins are easier to pump because the supply is tightly controlled and the mining emissions are reduced. Coins that eclipse a premine coin and draw away community interest destroy a key element of a pump and dump strategy: willing buyers to buy at the top (allowing the pumpers to "dump" their coins).

Hypothesis: BCX is associated with one or more pump groups or hired by them to FUD-attack coins that draw interest away from more readily pumpable premine coins.
2618  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [XMR] Monero - A secure, private, untraceable cryptocurrency on: March 13, 2016, 07:14:55 AM
So I decided to email Kraken with the same request.  Please add Monero to your exchange.  I'll probably get the same form mail back in my inbox.  But let the pressure on them build.


This is what they sent me:

We're following Monero. I doubt it gets added any time soon, but I know we're watching for new ones to add all the time. Thanks for the message.

Best,

Joseph
Kraken Client Engagement

Wow, not a form letter this time!

Well, we're approaching a sustained high level of 24 hour volume. Any coin that approaches the 1 million USD 24 hour volume mark will probably get the attention of a lot of exchanges.

Maybe they could replace one of the their coins that have 30K USD or less in volume

Oh haha my bad. I wouldn't have known until you said

Not at all, you didn't do anything wrong, I was just explaining why I don't want to do another loan right now.

I know there is another XMR clone called BBR.

BBR is not a XMR clone. Both are derived from Cryptonote/Bytecoin.


When I hear "CryptoNote clone" I think of DSH (intended to clone BCN without the 82% premine). Most (active) CryptoNote coins have diverged quite a bit already.

That is a good point. DSH is the only currently-active one that is a clone of anything.
