401  Economy / Service Discussion / Re: Escrow list on: September 01, 2015, 01:18:12 PM
I will be going over this again at some point,

I am a little stuck, this list is large with lots of members shouting to be on the list (most are new with less than 100 activity)

So I need to think better about the format, I welcome any ideas.

I still like to try and keep this going, it' still a popular thread.


Maybe you can add them all but include a sort order. I think trust ratings, activity and so on might be good indicators to sort that list. So that you can list the least risky escrows at the start.

I don't think the list should be sorted after how much fee someone is taking. It would be too easy to get to the top for new escrows.

What i wonder is why should someone go through the trouble to get a doctor only to earn nothing at the end. Do you mean it only comes from a minority that was NOT discriminated there?


Well, in communist countries education tends to be very cheap or free and can be of excellent quality, the problem is that there is no place for this people to work.

Don't steal my quotes! Tongue

And yes, i know. Education should be free everywhere ideally. But even if it is. You have to invest a lot of work and time and mostly you don't have much money on the way. Maybe you even have to work while studying.

So it is quite troublesome. I guess only idealistic persons would go through all that only to earn practically nothing at the end.

Ha, it's 2015 and people still think NSA can't find you through a proxy  Shocked

I doubt the question was about secret agencies. I mean before you have to fear them you have to do pretty bad things. I think protecting against hacker or maybe even the police is a lot easier. It is unlikely that the NSA would give the police tips about someone only doing bad things the police would be interested in. They would reveal their possibilities by doing so.

makes me excited ...nothing other than GAMBLiNG!! at least in crypto world ..
there was a time when i was literally shaking to do MAX bet of 8+ coins ..but i won that.


Hm... reading that makes me actually happy that i'm not the same. It sounds like an addiction, like when you need your drugs or your alcohol. I would not want having it that way. I mean i would know it's wrong and still would have to do it?

I'm glad.

The first rule of Illuminati is you don't talk about Illuminati.

I think you should. Only not showing that you have inside infos. Not speaking about illuminati might look suspicious. I think it's safer to hide directly in the danger.

Does that mean the best hospitals in the world are in Georgia?

Georgia is an emerging medical tourism destination, which attracts patients from all over the world (especially from Turkey, Middle East, and Europe). The medical education system of the former USSR was one of the best in the world. And ethnic Georgians faced no discrimination from the Slavs (unlike the case with Azeris and Uzbeks), and a large number of them graduated out of these institutions. Most of the doctors are very experienced.

Interesting. Are prices for cosmetic surgery very cheap too?

What i wonder is why should someone go through the trouble to get a doctor only to earn nothing at the end. Do you mean it only comes from a minority that was NOT discriminated there?

Poor Russian people
And the worsest thing is that human there can be imprisoned by doing nothing, just expessing opposite point of view.
Putin is a real weirdo.

Well.. 85% of the Russians are supporting Putin according to the opinion polls being conducted by Western agencies. So he must be doing something good for the Russian people, right? And the game of sanctions and embargoes were started by the Europeans and the Americans. Russia imposed the counter-sanctions as a retaliatory measure. And the European farmers are losing billions of USD as a result of it.

BTW... you need to improve on your English. Are you from the Philippines?

I believe that is coming from the mentality of russians. The police is not to trust there. So they take the right in their own hands often enough. And criminals are often enough heroes. So they think putin is a strong person that took what he wanted and because of that they like him.

At least that's the impression i learned while having a russian girlfriend. Smiley And yes, even girls can fight there. Cheesy
408  Bitcoin / Bitcoin Discussion / Re: What are the downsides to 8MB blocks? on: August 31, 2015, 12:37:36 PM
This chart says it all



For broadcasting large blocks, it will take 0.25 second for each KB to reach every nodes. So 1MB blocks would take 250 seconds e.g. more than 4 minutes to reach all the network, or 80 seconds to reach majority of the network

It is easy to calculate, for 8MB blocks, it will take 32 minutes to reach all the nodes, or 10.6 minutes to reach majority of nodes, it is obviously too slow, the next block is already mined before the previous one arrived, so the previous one is always orphaned, the network will be segmented

http://www.cs.ucsb.edu/~rich/class/cs290-cloud/papers/bitcoin-delay.pdf

Of course there will be workarounds to broadcast only the block header first then followed by the block, but that function is not implemented yet and have its own weakness. Currently some chinese miners try to include as little transaction as possible to increase the speed of their block's broadcasting

First, it will take a lot of time until the bitcoin network will have enough adoption to fill 8 MB Blocks.

Second... there is a network that is used to propagate blocks fast to get above 50%. Which is what it needs to not being orphaned anymore. That network was set up for exactly that reason and it can propagate full 1MB blocks very fast. Only a couple seconds.

That was done to show that miners don't need to create 1 transaction blocks in order to have an advantage in propagation.

So for now this is a non existing problem.

Why would you need 2 TB SSD to store 512 MB of data? (we are talking about running a node here, right?) Even if you wanted to store the full blockchain 2 TB HDDs are cheap and would be enough for long time to the future.

How do you maintain all blockchain when block size limit will be 8 MB? Blockchain is almost 50 GB already. It'll be 63 GB before new year. Imagine we see 8 MB blocks every 10 minutes. Even 2 TB would be obsolete in 5 years.
If you don't want any problems you don't store your blockchain in HDD. You need a good SSD. Running Bitcoin Core is very expensive even right now.

Then where will all these transactions come from suddenly? You know that the 1MB blocks were not full until the spamming began? It is not imaginable that suddenly 8MB blocks are always happening. Even spammers could not afford these costs.

So you shouldn't fear these block sizes.
410  Bitcoin / Bitcoin Discussion / Re: "Why I'm releasing a brainwallet cracker at DEFCON 23" on: August 31, 2015, 10:03:23 AM
Come on man, people who know how to choose good passwords and store them correctly while using brainwallets are as safe as using other "normal" wallets. I have seen so many stupid missuses with the wallet.dat files so far that are as bad as bad brainwallet passwords.

This means nothing, if people are using brainwallets, they are not less safe automatically.

Yes, they absolutely are less safe automatically.  A person who wants to break your wallet.dat password must have your wallet.dat file.  Brainwallets have no file.

Brainwallet cracking tools can run extremely fast - the cracking can be run offline against an indexed version of the blockchain, and can be distributed among many bots.   A password of "m2wAHUnF91z" for instance (created from LastPass, and bearing approximately 51-57 bits of entropy, depending on how it's calculated) is absolutely reasonable for a wallet.dat password.  It is absolutely NOT fine as a brainwallet key.  Brainwallets should have no less than 128 bits of true entropy.

Creating a safe brainwallet is possible, but it is very difficult to do correctly.  You have to forget everything you've learned about how to pick a good password.  

That is interesting. But i don't understand yet why there is such a big difference in safety for having that passkey as a password for the wallet.dat or having it as the seed for a private key. Where does the difference come from? I mean bruteforcing should work at the same speed for both isn't it? Or are there iterations of the pass for the wallet.dat so that the time to bruteforce gets extended?

You might want to check out NuBits. You can provide liquidity that is used to make the altcoin stable. One nubit will always be worth one USD. And you get rewarded for providing the liquidity.

I have tried p2p loaning and I have been satisfied this far.

What is p2p loaning?

I had the thought to open a service like you but did not go through because i thought that very fast it will be explained what it is about. Making it useless at the end.

On top people are cautious about why you would want to buy them. Guess too many scams happened so everyone fears a bad thing. Cheesy
413  Economy / Services / Re: 50% off Flights and Hotels Service on: August 30, 2015, 09:30:03 PM
This thread definitely looks interesting. I'm interested to hear if someone trusted tested this service and if after a couple of weeks nothing happened then it might be a nice thing.

Though i fear there is no real way to provide that discount. For every travel on top. It must be something completely independent from the company offering the travel. So it has to do with the kind of payment.

So 50% would be huge for amazon gift cards already.

Really... i can't imagine how this could work legally. But if a trusted member gets good experiences then i might overthink my scepticism. Smiley

Trust no one. Except you know him or her very good.

And

If you want to achieve something work for it. Don't sit around and wait it coming somehow to you. Or even worse, think that you can't get it and envy those that have it. Act and work on it and something will happen slowly.
416  Bitcoin / Bitcoin Discussion / Re: What are the downsides to 8MB blocks? on: August 29, 2015, 12:42:39 PM
A good argument against the bitcoiners that demand 1MB blocksize because "Miners have to be rewarded" is the electricity that goes away with that. I recently read an article about a study saying that currently 1! bitcoin transaction costs so much electricity like 1.75 normal US households use in a day.

We can't let all these miners survive artificially by raising the fees. The amount of miners need to be trimmed down and the bitcoin security be more power efficient. That was always happening and it should and can't be held up artificially. The bitcoin network would be still very very secure with less miners.

Unfortunately miners are the mighty ones in the game. We only can hope that the sane one are the biggest ones. And that they see the need of bitcoin adoption for getting future profits.
417  Bitcoin / Bitcoin Discussion / Re: What are the downsides to 8MB blocks? on: August 29, 2015, 12:35:03 PM
There are some problems with bigger blocks, as far as I can understand bigger blocks means:

1. You need to have more HDD place to store bigger blockchain.
2. Transactions fees will be actually higher, RIP bitcoin microtransactions.
3. Higher blocks also requires higher internet bandwidth.

Point 1 is not really the case. I mean the 8MB won't be filled magically suddenly. Where should these transactions come from. And when you would stay at 1MB only because of that then bitcoin would be unuseable since ALWAYS transactions would not be included. What kind of transaction system would it be when you can't trust that it transfers?

Point 2 is wrong. The fee will grow without a bigger blocksize. With 1MB blocksize for example everyone would pay higher fees to get their transaction included before others.

Point 3 is the same like point 1.

It will solve the spam attacks problem.
How is that? What prevents anyone from sending 8 times (or 100 times) as much spam as what we've seen recently?

What we need is a slight change in the default fee setting for Bitcoin nodes, that still allow very cheap payments (also micropayments) but helps against mass spam / dust transactions. Something similar to what Litecoin does, by requiring an additional small fee for each small output in a tx (and perhaps for each small input as well, while we're at it).

Will you do it? You would be poor pretty fast. Even the small KB that were needed to fell the 1MB were already expensive. Imagining that someone would spend the money to fill 8 MB blocks is hard.

It simply would not make any sense in any way to spam that way.
419  Bitcoin / Bitcoin Discussion / Re: What are the downsides to 8MB blocks? on: August 29, 2015, 11:55:50 AM
The biggest downside is basically the fact that the blocksize will be bigger, therefore limiting the amount of people that can access to it, or they could still access to it but it will be slower to download it.

Not really. Where should all these additional transactions come from suddenly to fill the 8MB? The blocks weren't full up to the spam attacks so why should suddenly there be so much more transactions?

If you think about spammers then no, that would simply be way too expensive.
420  Bitcoin / Bitcoin Discussion / Re: What are the downsides to 8MB blocks? on: August 29, 2015, 11:53:46 AM
8MB per 10 minutes is about 13.6 KB/s. What was the problem again?

Not that I think that simply increasing the block size limit to 8MB is a good solution (I'd rather see something more dynamic) but if 13.6 KB/s is actually a problem, maybe you should fix your internet, rather than debate over Bitcoin.

Miners cant wait 10 minutes to have their newly mined block trasfered to the next node.

What do you mean with that? Miners can propagate really fast. An there is a project, i'm not sure anymore what it's name was, that was created to propagate blocks faster. And they get >50% in 2 seconds or so when using that network. My numbers might be wrong but it was so fast that creating 1 transaction blocks made no real sense.
