Centralized marketplace platforms have the ability to provide a level of service and reliability that mainstream users have come to expect, but may also lack transparency, charge high fees, and impose rules that users may not agree with. That's where decentralized marketplaces come in. Below we explore what they are, how they work and give some examples of decentralized marketplaces in action.
Decentralized marketplaces are what blockchains are all about. They allow people to interact and transact on a global, permission-less, and self-executing platform. Houses, hot sauce, and t-shirts can all be bought and sold without needing to trust a middleman.
At its core, a decentralized marketplace matches buyers and sellers of goods and services. Most of the important functionality like executing trades and releasing funds are controlled by a smart contract or program instead of a person.
It means that buyers and sellers agree to terms and when the terms are fulfilled, the transaction is automatically executed by the program. This makes decentralized marketplaces permission-less, resistant to censorship, and trustless. Because they tend to use cryptocurrency for payments they also have all the benefits of a global 24/7 payment system.
The biggest difference between a centralized and decentralized marketplace is the need for middlemen or intermediaries. Without middlemen, fees are less necessary and sometimes not required at all. The rules of the marketplace are also completely transparent and cannot be changed without the user accepting them. When services such as reviews, reputations, and dispute resolution are added, then decentralized marketplaces get many of the benefits of traditional marketplaces with added transparency and less fees.
There are many different types and setups for decentralized marketplaces. Here we will focus on blockchain specific marketplaces, marketplace applications, and marketplace platforms.
Syscoin is a blockchain protocol or network that has a built-in platform for e-commerce and decentralized marketplaces. Users can take advantage of Syscoin’s application-specific blockchain, which has high transaction rates as well as high security because it is “merge-mined” with Bitcoin. Furthermore, the Syscoin blockchain is interoperable or compatible with other blockchains using the Syscoin Bridge.
OpenBazaar is not its own blockchain, but instead acts as an application that is peer-to-peer or directly connects users of the application who want to trade. It has many of the benefits of being a blockchain such as not having to rely on a central authority, middlemen, or a central database, but since it is just for transacting trades and e-commerce, there is no need for miners or complex consensus algorithms.
OpenBazaar also has the benefit of no fees or restrictions on use. Anyone is able to download the software and start trading. The program uses multiple cryptocurrencies for payments such as Bitcoin, Bitcoin Cash, Litecoin, and Zcash.
Another way for decentralize marketplaces to exist is through a platform or protocol where developers create tools that allow other people to create their own peer-to-peer marketplaces. Origin Protocol and the Origami Network are two projects that are doing this using the Ethereum blockchain. By creating a system of standards and smart contracts, these platforms allow nearly anyone to spin up their own decentralized marketplaces. Both platforms also allow users easy and simple ways to manage listings, escrow, reviews, ratings, and buyers and sellers.
Some decentralized marketplaces have their own token to help facilitate how the marketplace functions. Syscoin users are able to create their own tokens on top of the Syscoin Platform called Syscoin Platform Tokens (SPT). Origin Tokens are intended to be used for governance decisions with Origin token holders being able to influence platform decisions. The token also rewards users, developers, and marketplace operators. Origami has its own ERC20 token called ORI. ORI is used for dispute resolution as well as in their decentralized payment system and allows for lower transaction costs.
Most decentralized marketplaces allow you to buy and sell nearly anything and pay using cryptocurrencies. Decentralized marketplaces let you save on platform fees and are accessible anywhere without needing to provide personal information or trust a central provider.
Since decentralized marketplaces are still nowhere near the size, scale, and usage of their centralized counterparts, the challenge for nearly all of them is to get more buyers and sellers on their platform. As with the rest of the crypto industry, adoption is key.
It’s no secret that crypto wallets need a makeover, and fast. But as the pieces and players leading this makeover emerge, so too is a fight over what to call the effort. Some call it account abstraction, others call it EIP-4337. “We call it a smart wallet," Argent cofounder and CEO Itamar Lesuisse told Decrypt. "It’s as simple as that.” Argent, along with Safe (formerly Gnosis Safe), is at the forefront of the account abstraction movement, making crypto wallets easier, and smarter, to use. Walle...

Everyone’s experimenting with ChatGPT, even crypto exchanges. Coinbase recently turned to artificial intelligence to experiment with how accurately ChatGPT could carry out a token security review—a requirement for all tokens listed on the exchange. After reviewing 20 different smart contracts, the mega-popular AI tool produced the same results as the manual review 12 times. However, of the eight misses, five were cases where ChatGPT incorrectly labeled a high-risk asset as low-risk, which is the...
