A cryptocurrency (or crypto currency) is a digital asset designed to work as a medium of exchange that uses cryptography to secure its transactions, to control the creation of additional units, and to verify the transfer of assets. Cryptocurrency mainly uses decentralized control with all transactions recorded in a database called Blockchain. The first decentralized cryptocurrency created was Bitcoin in 2009. Since then, the crypto world has grown exponentially in the last couple years. Massive adoption of blockchain technology cannot be evaded in the coming years as cryptocurrency is becoming increasingly easier to access and own. There are at least 1500 cryptocurrencies currently in the market. One of these is Ethereum. Ethereum implemented a decentralized platform that runs a smart contract, which is a decentralized application that runs on blockchain. Callisto Network is a project of Ethereum Commonwealth that’s been researched and designed, and has developed a reference implementation of a self-sustained, self-governed, self-funded blockchain ecosystem. It also improves the security of the ecosystem of crypto industry by improving smart-contract development methods and environment. Another goal of Callisto Network is the implementation of experimental protocols, which are a combination of core features implemented in smart-contracts and merged protocol-level configuration. An important point is the ability to implement key platform features using built-in mechanisms: ie smart-contracts. Callisto Network aims to define and standardize protocol for a reference implementation of built-in cold staking, governance system and a development funding mechanism based upon smart-contracts.
