The World’s First PoS Smart Contract Token

Airdrop Bitcointalk Github Twitter Slack Telegram Whitepaper

PoSToken is the world’s first Proof-of-Stake smart contract token on Ethereum platform. It’s based on the ERC20 Token Standard and implements all standard methods. As an Ethereum token, PoSToken first implements the Proof-of-Stake mechanism, meaning that holders of PoSToken can earn some extra tokens just by holding PosToken for a period of time, greater than or equal to The Minimum Coin Age.

Furthermore, the idea behind PoSToken is not only to issue a simple Ethereum Token with Proof-of-Stake mechanism but also to define a brand new Token Standard for Proof-of-Stake tokens. A interface including some standard functions was defined in the code of PoSToken, we call it PoSTokenStandard, which is like the ERC20 standard. It’s a new Token Standard devised specifically to help developers easily issue Proof-of-Stake tokens. It’s a real innovation and we believe that a new era of Crypto Tokens is coming.

PoS Mining Guide


Holding some PoSToken for a period of at least 3 days, greater than or equal to the Min Coin Age

1.Sending a transaction to your own address with any amount of POS.
2.Using or Mist or any other software that can interact with contracts to execute mint() function.

Not sure about your account’s coin age or current interest? Executing these functions:
1.annualInterest() : Return current annual interest.
2.coinAge() : Return coin age of your account. Return 0 means that your token doesn’t meet the min coin age now
