Cryptocurrency is a transaction medium that uses cryptographic principles to secure transactions and control the creation of trading units. The cryptocurrency is a kind of digital currency (or virtual currency). Bitcoin became the first decentralized cryptocurrency in 2009, after which the term cryptocurrency was mostly referring to such designs. Since then, several similar cryptocurrencies have been created. They are often called altcoins. The cryptocurrency is based on a decentralized consensus mechanism and is opposed to a banking financial system that relies on a centralized monitoring system.
So Bitcoin is one of the representatives of cryptocurrency, but in addition to more representative cryptocurrencies, there are some cryptocurrencies that are not known to people, E.g:
1.Waltonchain
Waltonchain combines blockchain with IoT (specifically RFID) to create a management system for supply chains. The project is named after Charlie Walton, the inventor of RFID technology and a pioneer in the space.
Logistics systems are complex and commonly involve several different parties. As these systems grow, it becomes increasingly tough for businesses in the same vertical to coordinate with each other. On top of that, individual entities may have different processes that further hinder the ability to transfer data back and forth.
2.Komodo
The Komodo blockchain platform uses Komodo’s open-source cryptocurrency for doing transparent, anonymous, private, and fungible transactions. They are then made ultra-secure using Bitcoin’s blockchain via a Delayed Proof of Work (dPoW) protocol.
Judging from the situation on citicoins.com, as of the current 11/6/2018, the Komodo price has dropped by 8.05%. From the development trend chart, there is still a downward trend.
