Bean Cash is a re-brand of the digital currency and network, previously known as BitBean. It was the first 'crypto-currency' to implement a maximum of 20MB block sizes, based on Gavin Andersen's proposals to fix Bitcoin's scalability limitations. BitBean was also the first 'crypto-currency' to pioneer the use of static block rewards in a Proof of Bean (PoB) system -- which now makes energy wasting PoW (Proof of Work) systems, inefficient, expensive and archaic!
