Riecoin is a peer-to-peer network without a central authority and intermediaries. The Riecoin API is identical to the Bitcoin API. The p2p network protocol is also borrowed from Bitcoin and modified. A basic mining software is built into the client, however, an optimized fork of the CPU miner will also be released soon. Optimized mining requires the use of a filter, which usually creates an inefficiency zone for accessing RAM, so it is difficult to predict what improvements could be made using a GPU. Surely someone will find a way to implement an efficient GPU miner. The same with ASIC equipment. However, if an ASIC suitable for such purposes is created, an ASIC would also be produced, which could be used to find interesting prime number structures. The meaning of Riecoin is as follows: the mining process, in addition to performing its function of providing the network, generates a series of prime numbers as a by-product. These prime numbers are in the interests of mathematicians and the scientific community.
