Syscoin is a decentralized marketplace where users can trade goods, services, and digital assets. The company launched the Blockmarket in 2017; a global commerce platform that would leverage the benefits of blockchain to eliminate intermediaries and drastically reduce fees. Users can either sell their own products, or create virtual stores that sell a variety of products from other businesses. Syscoin wants to take out the middle man and create a commerce platform like eBay, that is easy to use and will have minimal fees. The network is powered by the native SYS coin, but users can also pay with other cryptocurrencies. The blockchain has a Proof-of-Stake (PoS) consensus mechanism.
Syscoin has a number of features that make it user-friendly and facilitate trading. These features include: user aliases that allow you to make payments without having to enter lengthy wallet addresses, escrow services to build trust between buyers and sellers, and an integrated exchange where users can trade a wide variety of cryptocurrencies.
