Dave here again, back to teach you how to chat safely and securely via the XMPP/Jabber messaging protocol.This tutorial will be done on Windows 7, but the same idea should be transferred across Linux distros and Mac OSX.The first thing you are going to want to download the XMPP client called Pidgin.This can be downloaded here.Once it is downloaded, go ahead with the install to completion.Once it is installed, start up Pidgin.You will be presented with two different Windows.Ignore them for now.We have to first go grab the software that will allow us to chat securely.It is called OTR, which stands for Off-the-Record messaging, and can be downloaded here.Download and install it.Make sure that the Pidgin application is closed out from your screen and taskbar before installing OTR.OTR and Pidgin are now installed!No more downloads from here out in the tutorial, just a few simple configurations to Pidgin.The first thing we need to do is make the OTR plugin active in Pidgin.Do this by opening Pidgin, going to the “Tools” drop down, selecting “Plugins”, and clicking on the checkbox next to “Off-the-Record Messaging”.

Once we are done with that, we can enter our XMPP account details and start chatting, or make a new account if you do not have one.If you need a list of free XMPP service providers, you can get one at this link.You can register through the client, like I will show you how to do, or you can register online from this link.bitcoin calculator indonesiaThe first step to register from the client will be to enter the username, password, and domain.ethereal blade heroes” without the quotation marks.buying bitcoin for darknetThe “Resource” box should be left blank.bitcoin mining ekran kart?Next, check the “Create this new account on the server” box at the bottom of the screen.scan for bitcoin virus

It should look something like this.The next steps, to take one more step to be even more secure, will to set Tor as a SOCKS5 proxy, so that not only are the messages encrypted with OTR, but the traffic is encrypted with Tor.To do that, click on the “Proxy” tab, and set your “Host” and “Port” accordingly.bitcoin over 10 jaarMake sure that Tor is running as well, or you will get connection errors!bitcoin thai clubOnce this is done, click on the “Add” button, go back to the “Buddy List”, click on the “Accounts” drop down, click on “Manage Accounts”, and finally click the checkbox next to your account.bitcoin gpu amazonThis will send the request to the server, and ask you to confirm your new account.bitcoin dans 10 ans

If you get an error that pops up, don’t be worried.Sometimes, there is an error with the server, and you will have to register online.This has happened to me several times, and is normal.Just register on the website of the XMPP host you are using.Once you have done all of this, you need to add your buddy and get in a chat with him or her.I will be using a fake account for this example, but the same actions transfer over to when you chat with a real account.All you need to do is click on the “OTR” button in the chat room, and click “Start a Private Conversation”.Wait a few seconds, and just like that, you are chatting securely via XMPP.I hope this tutorial has been helpful, and as always, if you have any questions or problems, feel free to post a comment, and I will do my best to help.Thank you so much.During the year 2005-2006, I became a decentralization whore.I realized that, with XMPP, nearly anything could be decentralized.With one exception: online payment.Paypal was highly successful but also highly centralized.

Was it possible to build a decentralized version of Paypal?I came with a solution which involved web of trust and shared debts around a virtual currency, which is more or less a kind of solution that the Ripple project is exploring.I thought that it was too impractical and not really appealing.I forgot that solution and the problem stayed in some obscure part of my brain.Then I discovered Bitcoin.And I realized that my mistake was to consider the value of my virtual money as granted and as linked with a fiat currency.Bitcoin was the decentralized Paypal, someone did it!Now, after a few months using Bitcoin, I’m not so sure anymore.Bitcoin suffers from to many problems, which are all usability related.In short, it was conceived by a geek.First of all, it is impossible to grasp the concept of bitcoin easily.When I see comments on my posts about bitcoins, I realize that most people simply don’t understand what it is.It is way too abstract.It is also a pain to use: you cannot send a message with your payment, you have to copy/paste long strings of random characters.

I don’t even talk about accepting bitcoins in a real-life situation: both parties should have a laptop with them and do all the operations on the fly while waiting for the network to send confirmations.Because usability is poor, security is bad.People don’t understand what they are doing and have their bitcoins stolen by malwares and viruses.Not to mention people losing bitcoins by sending them at a bad address or crashing their hard drive.Not to mention the fact that buying bitcoins is complex.You have to find your way through the jungle of bitcoin exchanges like TradeHill, Bitcoin7 or bitmarket while listenning to horror stories about MtGox.Bitcoins users are happy, indeed, but they live on an island.Bitcoin is not the decentralized Paypal I was hoping for.But could we use Bitcoin to build a decentralized transaction solution?I called that « Bitcoin banks », although the term might be inappropriate.In the following paper, I describe how a « Bitcoin bank » should work, allowing to send money directly to your mail address thanks to Webfinger (something I already discussed before).

In the shorter term, implementing such a bitcoin bank would mean solving most usability concerns.It will allow people to accept bitcoins without the risk of losing value and put all the security efforts on a professional service, not on the end user.As a nice bonus, it could effortlessly decentralize the exchange market.It also has many other scary implications and I’m probably missing most of them.Yes, it might completely change our society, making the banks a simple useful services without the power they currently have.So, please read and give me your opinion.If you are willing to implement such a service, don’t hesitate to contact me.This could really be the next big thing.I also hope that it would appeal to people behind OpenTransactions or Flexicoin.It might even be compatible with Bitcoin’s alternatives like Open UDC.Description of a Bitcoin Banking system (PDF – 75ko) I plan to release the document under a simple CC By license after some more work.In the mean time, donations are appreciated at 15SCCTDK9xcZyKFWXsPRXYS9s1m3Mikcxs.
