Anyone to explain what is the notary system in openbazaar and how it works?

From: https://blog.openbazaar.org/what-is-openbazaar/

How does OpenBazaar work?

Let’s say that you are looking to sell your old laptop. Using the OpenBazaar client (a program you download), you create a new product listing on your computer with details just like you would on any ecommerce site, and ask for a price in Bitcoin. When you publish that listing, it is sent out to the distributed p2p network of other people using OpenBazaar. Anyone who searches for the keywords you’ve used—laptop, electronics, etc—will find your listing. They can then accept your price, or offer up a new price.

If you both agree to a price, the client creates a contract between you both with your digital signatures, and sends it to a third party called a notary. In the case of a dispute an arbiter can be brought into the transaction. These third party notaries and arbiters are also folks on the OpenBazaar network—could be your neighbor or someone across the world—who the buyer and seller trust in case something goes wrong. The third party witnesses the contract and creates a multisignature Bitcoin account (multisig) that requires two of three people to agree before the Bitcoin can be released.

The buyer then sends the agreed upon amount to the multisig address. You get a notification saying the buyer has sent the funds, and you ship the laptop to them and mark that it has been shipped. The buyer receives it a few days later, and they mark it received, which releases the funds from multisig to you. You got your Bitcoin, the buyer got the laptop; no fees paid, no one stopped your trade, everyone’s happy.
What if something goes wrong?

As we all know, things don’t always go smoothly. What if you’re buying a certain book from a seller, you pay the multisig, and they ship you the wrong one, or it was in poorer condition than advertised, or they don’t even send a product at all?

This is where the third party comes in. Remember that a multisig requires two of three people to agree in order to move the Bitcoin. They control the third key to the multisig, so the funds will not move until either the buyer and seller work out an arrangement themselves, or the third party agrees with either the buyer or seller on how to deal with the transaction and funds in multisig.

How can you trust the third party to begin with? For that matter, how can you trust anyone on a network that guards users’ privacy, thus allowing for pseudo-anonymity? OpenBazaar has a reputation and rating system that allows all parties to give feedback on other users. If someone attempts to scam another user, their reputation will suffer, and the same is true with third parties. When you go to purchase a product and select a third party for the transaction, you can see their reputation and ratings to find out if the rest of the community trusts them—or doesn’t. Ensuring that these ratings are legitimate and the reputation system isn’t being gamed is a difficult technical challenge, but you can read about our approach here.

If you are really paranoid, both the buyer and seller can create a voting pool made up of people they both trust.

These steps may sound complicated, but the details are handled by the client itself. Our goal is for buyers and sellers to have an even better experience using OpenBazaar than the old centralized platforms.

https://www.reddit.com/r/Bitcoin/comments/33dir7/the_openbazaar_04_beta_has_just_been_released_for/

The fourth OpenBazaar beta has been released, named after the famed Portobello Road Market in London.

Please note this is still a beta and for users with some level of technical expertise. This isn’t a consumer ready release.

Binaries will be released soon. Windows users will need to wait for binaries. You can install beta 0.4.0 on Linux or OSX using the following instructions. For a detailed overview of the 0.4 beta client, visit this post.

We’ve also released quick start guides, visit these links for buyer, merchant, and notary.

This release includes a substantial number of new features and improvements. Most notable are the networking changes, which should allow better connectivity and largely eliminate the need for port forwarding. Also greatly improved is stability. Other improvements include:

- Signing keys are now HD for increased privacy;
- Internal messaging system for online parties to communicate;
- Users can now select their avatars;
- Images are now externally hosted and listings can support three images (including gifs);
- Notaries can now offer refunds to buyer or release funds to seller;
- Notaries can now set their fee (as a percentage) if their services are utilized;
- The order workflow has been significantly improved;
- Addition of simple walk-through on start up ;
- Search improvements.

Installation

If you don’t have Git installed on Linux, open terminal (Ctrl+Alt+T) and type:

sudo apt-get install git

If you don’t have Git installed for OSX, download here and install.

Now run:

git clone https://github.com/OpenBazaar/OpenBazaar.git

Once that’s complete, change directories:

cd OpenBazaar

Run the configure with this command:

./configure.sh

If you’ve already been running OpenBazaar, you need to update the code. In terminal, run the following commands:

git pull

./configure.sh

Please note that as of the 0.4 beta release, the default branch will be develop instead of master. This means that beta testers will receive more frequent updates if they run ‘git pull’. If you prefer to keep to the more stable releases only, then switch to the master branch by running this command:

git checkout master

To start your node:

./openbazaar start

To stop your node:

./openbazaar stop

To get help on the commands you can use with OpenBazaar:

./openbazaar help

If you find a bug, please let us know on our Github or on the bug reporting thread in our subreddit.

When I run ./configure.sh on OSX I get:

Updating, Upgrading and checking brew installation...
error: The following untracked working tree files would be overwritten by merge:
   Library/Formula/nailgun.rb
Please move or remove them before you can merge.
Aborting
Error: Failure while executing: git pull -q origin refs/heads/master:refs/remotes/origin/master

Edit: forced it:
git checkout -f ./configure.sh

Then I hit this:

./openbazaar start
Traceback (most recent call last):

  File "/Users/justinsmith/Applications/OpenBazaar/node/openbazaar.py", line 14, in <module>
    import psutil

Now doing this:
brew install psutils

you must delete the old database there

Thanks - this did it! This little guy was hiding, but I found him:

rm /usr/local/Library/Formula/nailgun.rb

./configure.sh then works just fine, and I was able to launch OB.

Cool!

I've got a OB shop open now with a contract for a cell phone for sale. Let me know if you find it.

The interface is a little wonky but it's definitely improved since earlier versions.

It would be great if we could eventually build a native OB app that runs on a cell phone connected to a data network, that way it could run in the background anytime there's network connectivity.

[chek2fire]

what is your shop number?

[TippingPoint]

From the wiki:

Your store must be online in order to respond to contract queries and/or accept orders

Makes sense.  There is no centralized server.  That explains why the stores come and go depending on the time of day.  They are only there while each PC is on and they are logged into the OB network.

[687_2]

what is your shop number?

I believe it is:
af628a03a01ff38c453279818b6ba9f488187d20

Edit: I had to restart OB, apparently my store crashed.

[chek2fire]

it has some crashes if you have the stable version. Try develope. They say they have fix the crashes

[duckydonald]

That's awesome! Can't wait for the Windows version.

Windows version won't see the light of day for a while, they said it would come out like 6 months ago.

Why is there no Windows version?  Makes zero sense to me.

You guys want OpenBazaar to succeed and become the future of decentralized marketplaces, but don't release a version for the largest user base in the world?

Ass backwards, developers that's a come on man!

You understand it is an open source project and developers are not being paid? What are you waiting for to contribute instead of whining?

so they shouldnt be asking for donations then, cause they do ask for it.

I can't wait for the Windows release, I really want to open my store there but me and Linux just don't go together.

I can't wait for the Windows release, I really want to open my store there but me and Linux just don't go together.

No better time to learn and be more secure while on the net, it doesn't take long to get the hang of and if it is ubuntu you will be able to get a lot of help figuring out what is needed.

Really glad this has finally been released thanks for the update OP now going to check it out, it is about time i stop getting ripped of by ebay & paypal fees.

I work on the IT environment for years and personally Linux it's just a waste of time for me.

[chek2fire]

an open source system is never "waste of time". You must setup a dual boot asap!
