Darkforest data publishing market place
Sellers try and sell data all the time. After the data is sold, sellers have to trust that that the buyer will not give away or re-sell the data to a third party.It is easy to make copies of data so people will always be able to re-sell data. An alternative approach is to be paid to publish some data to everyone.Here we propose a way to publish data so that everyone is able to pay for it at once. Once a certain amount has been raised the data is published or the seller is unable to retrieve the funds.
