NYIAX, a forwards advertising contracts exchange, which was developed in conjunction with NASDAQ, combines the two main methods of purchasing advertising content–direct, old fashioned contracts between two parties and a real-time bidding environment. Like the more traditional way of buying and selling advertising space, the buyer and the advertiser come to an agreement on the specifics of a proposal, using blockchain as their core ledger. However, if one party is no longer able to meet the requirements of the contract, it can be traded or re-sold to someone else. This allows companies to only pay for the advertising that they use, and for advertising firms to be able to guarantee their revenue streams. NYIAX has received much positive feedback, and plan to go live in October. For more information, visit www.nyiax.com.
