SDZ is the token used by the SanDianZhong platform in order to facilitate the interaction between the users, as well as create a means of payment and transactions on the platform heavily built for the use of rewards. The SanDianZhong platform was created in order to combat some unappealing features of the blockchain-based freedom and decentralization. The idea behind the project is simple: to create a space where anybody could post a review of the blockchain-based project existing somewhere around the web, and, by storing it on the blockchain itself, stop it from being deleted or edited in any way that would benefit the projects in question. Furthermore, by using the distributed ledger technology to store the reviews, the reviewers participating in the project would have to be held accountable as well, since any review would be easily traceable to them.
