RAM is random access memory — the abbreviation of random access memory. It is an internal memory that directly exchanges data with the CPU. It can be read and written at any time, and the speed is very fast. It is usually used as a temporary storage for the operating system or other running programs data storage medium. BitRAM (BTA) uses high-tech such as blockchain and 5G to record and store data, creating a new data generation and application ecology with blockchain technology as the core, improving the value of data itself and improving the basic space of data. BTA's multiple encryption technology makes uploaded videos, pictures, and files more private. The BTA shared distributed server can identify how many T storage space the server has contributed through blockchain technology, and give the corresponding BTA as a block reward according to the contribution rate.
