Bither Platform (BTR) is a Three-layer and multi-mining project that is an answer to the energy consumption problem in PoW mechanism, The first layer is a fully functional and secure layer with a reward system for the miners. The second layer is where different projects like sidechains are going to be added. Scientific and research projects that are in need of computing power, are going to rent their required hashing power on the third layer.
Ability to reuse the computing power on the Bither platform generates a new source of income for the miners which is a perfect solution to keep the mining profitable in downtrend and bear markets. One of the characteristics that makes Bither a different project comparing to other projects that support sidechains is the independence of sidechains when issuing transactions, in other words, sidechains don't need to use the main layer's coins as a fee of the transaction, and they can use their own coins.
