🔥 Your Pitch

A decentralised online marketplace, that is an online marketplace on blockchain, has advantages over its centralised counterparts.

Centralised online marketplaces have the following characteristics:

1. A centralised company owns the platform, for e.g. Ebay, and takes a commission from sales.
2. The infrastructure is centralised, and can be hacked.
3. The company owning the marketplace can change terms and conditions (T&Cs) of trade at will.
4. You need to rely on third-party payment systems.
5. Your personal sensitive data is held by the centralised owner and they can sell it to third parties.

It‘s blockchain technology that gives a clear advantage to decentralised marketplaces. These advantages include:

1. Blockchain is a decentralised distributed database, and all nodes are involved in maintaining the database. Each has a full record of the database. There’s no central server for hackers to destroy.
2. It‘s a P2P network, hence sellers can directly transact with buyers without intermediaries.
3. T&Cs are coded in immutable smart contracts; besides they are transparent.
4. Payment process uses cryptocurrencies thus eliminating third-party payment providers.
5. Cryptographic hash functions, data encryption, and blockchain consensus algorithm make the system secure.

So basically, I would like to create such a platform where multiple vendors can upload their listings, and a buyer would directly be linked to the seller. The terms of trade will be open, transparent, and immutable. No tampering of transactions would possible. Payment between buyers and sellers will be direct, no intermediary has any role to play.
