Experty has developed a blockchain-backed calling platform that allows two or more parties to connect via an online audio or video call. The Experty application allows a knowledge provider to set their rate per minute, which is then paid by the knowledge seeker when they call. By using an Ethereum smart contract combined with off-chain software, this exchange is settled seamlessly through the Blockchain.

In this way, Experty adds value to the consulting industry: it simplifies the exchange of knowledge for currency. The knowledge provider can share his or her direct call link without fear of receiving either fraud or marketing calls, and they can display their availability schedule. The knowledge seeker saves time and money on his part, by contacting the wanted person directly, and paying only for the actual call time.
