Win a Trezor Hardware Device and a Limited Edition T-Shirt 🎁

It was announced on the 17th of July that the Particl Open Marketplace’s back-end code was now entirely compatible with mainnet and possible to use with a command-line interface. It was also announced that anyone could start generating market keys and any of them could be submitted on Github to enable market capabilities on the official Particl Desktop 2.0 build.

So let’s have some fun with it!

To celebrate this important milestone, as well as the upcoming Trezor hardware device support for PART, the Particl team will be giving away one (1) Trezor hardware device to 3 random people who submit a set of market keys of their own. On top of this, the team will also be giving away one (1) free limited edition t-shirt to every participant of this contest.

Let’s first understand what this contest and giveaway are all about: the creation and selection of market keys to be used as the default market on Particl’s Open Marketplace.

What are Market Keys?

To understand market keys, we need to refer back to the difference between user markets and the main interface of the Open Marketplace.

Market Keys are similar to PART address keys. There is a private and public key that identifies a PART address — market keys work in the same way. Markets within Particl Desktop have a public and private key. Users can view, buy and sell items on all markets they know the keys of. The default market on Particl Open Marketplace will have its public and private keys in the code and viewable by all clients. Users can also create other markets the same way. In these markets, only the clients or users invited to that market can view, buy and sell items on it. Just like PART addresses, the existence of these markets is unknown to everyone without the private key.

When installing Particl Desktop and enabling the marketplace, you can browse the listings by clicking on the LISTINGS tab. This takes you to the main interface of the Open Marketplace where anyone can publish, purchase, and moderate listings with no restriction. Additional markets, usually referred to as “user markets”, “VIP markets”, or “private markets”, can also be created by anyone.

These markets can only be accessed by manually inputting their market keys into your local Desktop client. They behave exactly like the main interface of the Open Marketplace: anyone with access to a specific market can publish, purchase, or moderate any listing it contains.

There isn’t any difference between these user-created markets and the default interface of the Open Marketplace. Both are fully independent markets that can be used, to their full extent, by anyone that’s connected to them. The only perceived difference is because the default interface of the Open Marketplace is a market that is enabled and displayed by default, without requiring you to manually connect your Particl Desktop client to its market keys, whereas user markets need to be manually connected to.

The main interface of the marketplace is exactly the same thing as a user market. The only difference is that everybody shares and knows the keys of the main interface. — Arnold Bansemer, Particl Developer

As you probably realize by now, even the main interface of the Open Marketplace requires market keys so that Particl Desktop can connect to it by default. And while no extra step is required by the user to connect to the main interface of the marketplace, this “connection” still need to be made before a new version of the Open Marketplace is pushed publicly.

Note: It is not required to generate a key to use the Particl Open Marketplace. When downloading and installing Particl Desktop 2.0 or higher, it will come pre-packaged with a market key already linked to the client.

And to do just that, an entity has to generate and choose what market keys will be used to host the main market of the Open Marketplace. This is where the community comes in…

How to Generate and Submit Market Keys

While the Particl team is building the Open Marketplace protocol, it doesn’t own or has any sort of control over the network itself. It is entirely up to the community of users to run and govern it. That also means generating and choosing what set of market keys is going to be used to display the main interface of the marketplace will be a 100% community-led process.

Note: Generating a set of market keys does not give you any special access, permission, or power over the market. Everyone that installs the Open Marketplace has equal rights and oversight over the generated market. This is not a trusted setup.

Indeed, the Particl team is inviting everyone to generate a set of market keys of their own and submit it on Github by creating a pull request in the appropriate repository. Doing so is pretty simple and straight-forward.
