The original experiment
It seems that the developers of the new token on the basis of the blockchain Ethereum managed to surprise the crypto-currency community with the original concept and method of obtaining crypto currency, which was named Proof-of-Facebook. The token itself was created as an experiment, during which it is planned to explore the process of acquiring value by crypto-currencies.
The new token is called Face and it can be obtained free of charge on the TokenFace project's website. To do this, you just need to link your Ethereum-purse with your Facebook account to identify and prevent multiple receiving tokens from the same persons.
