A fully decentralized marketplace

[boldfi]

If you do think that decentralized marketplace will be interesting, become popular and generate revenue, then do it, no one stops you from that, I am just stating my opinion about it.
I think that lots of infrastructures are using buzzword decentralization for marketing purposes, like they use the word AI (Artificial Intelligence) and Blockchain technologies.

Okay, let's say that decentralization offers privacy, the seller still knows your name, the post company and the delivery guy still knows that you are receiving an item and if decentralized marketplace is using Cloudflare, then CF also knows it too.
I think that eBay or Amazon doesn't experience server downtime, at least I have never had an issue and I was always able to shop, so, I wouldn't say that this is the benefit of decentralized marketplace, it's in a neutral side.
Censorship resistance in marketplace is not a bad thing because people are willing to sell illegal things if it gives them a good profit.
Again, it doesn't offer increased accessibility. I and everyone can easily access eBay or Amazon.

Thank you too for your opinion, arguing helps us to find a good problems and solutions.

While eBay and Amazon may not experience downtime, they do censor. These are lobbies-influenced markets.
Several cases of product's removal have been reported.

Amazon promotes products which fit the "right-thinking trend". Go on and try to sell a product containing too much plastic, its visibility will drop to zero, getting overtaken by woke products.
Of course i do exaggerate, but you get the idea.

Big techs are lobby-driven and always follow trends to sell more, censorship is real on those platforms. Not to mention your data are being stored, analyzed and sold to feed some other big tech..
I do not care about my delivery guy knowing i ordered a package on the weekend. I do care about Amazon knowing what exact reference i ordered at what time, while doing what..

If you are ok with those practices, a decentralized marketplace may indeed not fit your needs.

If the goods and services you sell in this market are legal, then what is the reason for making it decentralized? I can understand decentralization in mixers and services that may need to enhance privacy, but purchasing goods and products may be linked to knowing the buyer’s address, which makes it difficult to provide a service of a privacy nature. The market can be implemented for digital products not physical goods.

You can meet in a public place to exchange goods - no one needs to know your address.

Yes, but a market place like this must offer international transactions, so you cannot apply this to all scenarios.

There should be something that encrypt that kind of details and just provide a key to the buyer and seller, when they want to do business. (The key can change for every individual transaction)

This way, you do not have one large public database of all buyer and seller personal information that can be farmed with one click.

Well, at least in other places of the web such a decentralized marketplace is already a reality?

Check BlockAze for example. It encodes all listings and market acticity fully on the Bitcoin blockchain and is active right now.

Here is its source repository:

https://git.tchncs.de/BorealUS/blockaze

You can find tutorials on YouTube or its full manual and code in the above link. It currently forgoes escrow in favour of a trust/ranking system.

I think it fulfills almost all criteria here and is actively used / maintained. Due to its emerging popularity it's API has been
added on https://moofetch.mooo.com, next to other established tools like Fulcrum SPV.

Interesting thing. Not exactly what i mentionned tho. This requires running a client and connect to peers.

It is pretty interesting actually as it exactly mirrors Bitcoin in its possible usage.

• You can trade via a full node, which is the most secure as a local copy of the blockchain is used.
• You can trade via a trusted web based API source such as https://moofetch.mooo.com
• You can trade via a full node, which is the most secure as a local copy of the blockchain is used.

Interestingly,  there is even a client shipped that allows trade from the command line.
The best thing is, as a buyer you do not even need BlockAze - you can pay via normal transactions
from your Electrum Wallet which greatly increases adoption. As long as the transaction fulfills some criteria (easy!)
it is then properly parsed by BlockAze and then added to a sellers ranking etc.

You can even run your own market with this tool.

In the darker parts of the web this tool is quite the rage in some smaller communities, as servers cannot be taken down. Here are some images from the above Gitlab repository:

Where I live, BlockAze is merely classified as a blockchain search engine, which is why its API could be added to moofetch among others such as Fulcrum.

Greetings,

   Lately, I've been contemplating the feasibility of a fully decentralized marketplace. This marketplace would primarily operate through
   smart contracts, ensuring decentralization and seizure resistance.

   Indeed, all that would be needed to sell and buy on the contract would be the contract' address.
   From that anyone could open its custom frontend access, like an access point.
   So even an 'access point' being taken down, the core of the marketplace would still live somewhere in the wild on the blockchain.

   In the case of physical goods transactions, the contract would encrypt the buyer's home address with the seller's key,
   ensuring that only the buyer and seller could access it.

   To address concerns about scams, sellers could be rated through an upvoting system, and feedback mechanisms could be implemented.

   However, there is one challenge to consider: fees. Any action that involves writing data, such as posting a product for sale or upvoting a seller,
   would incur gas fees. Nevertheless, on blockchains with very low fees, such a decentralized marketplace could still offer significant benefits, in my opinion.

   So i'd like to get your thought and feedbacks of such a market, solely based on smart contracts.  

A fully decentralized market through smart contracts can provide security and decentralization in transactions, it can also provide other benefits, such as high transparency. Every transaction and interaction is publicly visible on the blockchain, reducing the risk of fraud. Apart from that, this market can also provide wider and fairer access for small and medium businesses, because it is not tied to third parties or central authorities. However, the fuel costs for each action need to be considered. Do you have any further thoughts on markets like this?
