 This repository store contract that aims at verifying one's ownership to a domain using Provable Ethereum API.
 
 The idea is similar to Let's Encrypt where one has to show that he/she has control over the domain by returning a specific content in a specific URL under the domain. In its current implementation (HTTPChallenge.sol), one must be able to return the address in the body section of an HTML file under http(s)://declared_domain/_address to prove their control and ownership over the domain.
