GPS is short for Global Navigation Satellite System. Chinese name: global satellite navigation system and global navigation satellite system.
GPS refers to all satellite navigation systems, including global, regional, and enhanced systems, such as GPS in the United States, Glonass in Russia, Galileo in Europe, and Beidou satellite navigation system
This article was written by Taylor Killian on his blog in August 13. He contrasted the three parity SDR platforms, thinking that the three products would be the most popular SDR platform of the coming year. I think this article is very valuable for reference, a simple translation of a turn around.The original is here:Http://www.taylorkillian.com/2013/08/sdr-showd

Blockchain Introduction
A blockchain is a data structure that is logically linked from the back to the block that contains the transaction information. It can be stored as flat file, which contains files with no relative relational records, or stored in a simple database. Bitcoin core clients use Google's LEVELDB database to store blockchain metadata. Chunks are

The blockchain uses an Internet-based (Internet)-on-Peer (peer-to-peer) network architecture. Peer to peer refers to each computer located in the same network is equal to each other, each node provides network services together, there is no "special" node. Each network node is connected with a "flat (flat)" topology. There is no service-side (server), centralized service,
Before and after the Spring Festival, the blockchain again blew our circle of friends: Three o'clock the continued force of the group, Venezuela's oil currency issued, "in the Cong" suddenly appeared, the price of the encryption currency fluctuations ...
Now the streets are talking about blockchain, and our blockchain technology salon has been in this atmosphere
