PoSToken implements a whole new concept for the proof-of-stake tokens on the market. It is an Ethereum based, ERC20 standard token. It is also the first Proof-of-Stake token to use a smart contract system on the Ethereum platform. Besides implementing all standard methods, this network also improves the traditional system functionality. This way, any token holder who is part of the community enjoys the power to earn some extra tokens just by holding PosToken for a period, greater than or equal to The Minimum Coin Age. On the second stage of its development, the PoSToken not only provides a method to issue a simple Ethereum Token with the Proof-of-Stake mechanism but it will also introduce a function to define a brand new Token Standard for Proof-of-Stake tokens. The standard is devised to help developers easily issue Proof-of-Stake tokens which will be applied in the technical configuration of the system.
