Ledder

The architecture of Ledder platform is made of three levels: the interface level is comprised of the multitude of nodes that handle the communication and computation load and exercise the function of a gateway to other two levels, which constitute the blockchain framework; the computing level is also made of nodes, which include blockchain registers, situated in data centers of Google, Amazon and such.

Finally, the network level is represented by the nodes, placed in close proximity to digital screens, which transmit bits of information about the displayed pieces of advertisement to the computing level.  

The ULD tokens will be used primarily for purchasing the advertisement space on screens, funding ad campaigns, and conducting international transactions. Ledder will also provide their customer with means for issuing stable coins pegged to fiat currencies, which will be used to facilitate financial relations between all network participants.

All interested investors can already start purchasing ULED as Ledder is having the pre-ICO sale that will run throughout the next two month, till July 31. There is also a chance to receive free tokens as Ledder also offers an airdrop program. The start price of 1 ULED is $0.01, though the minimum investment threshold is rather high, set at $10000. The project will also organize the STO where they will sell SLED, the security tokens that will be converted to Ledder shares. The dates of STO have not been specified yet.
