The Signal is an advertising marketplace based on the Ethereum blockchain. On the Signal Marketplace advertisers can list their offerings to a network of attention influencers. Once an offering is listed, attention influencers are able to generate a personalized affiliate link that directs to the advertiser's offering. The Signal token (SIG) is an ERC-20 compliant token that will be used to reward the influencers every time this attention influencer drives a click or sale through their unique link.
