BitBean is another alternative cryptocurrency. Its Proof of Stake is different from other coins. In addition to only giving all coins that have over 6 hours of age only 6 hours of age in the PoS calculations, the blocks which are found are static blocks similar to PoW. Each PoS block is 1000 coins.

"Bean Cash (Ticker: BEAN) is a re-brand of the digital currency and network, previously known as "BitBean" (Ticker: BITB). The "BitBean" blockchain and network began on February 13th., 2015. In 2018 a private company (unrelated to the cryptocurrency previously known as "BitBean") began using US Trademark authority to usurp the name "BitBean" for its own use. Pre-empting this action, in late 2017, it was decided by Bean Core to rebrand to Bean Cash to avoid unnecessary conflicts. 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 'cryptocurrency' 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!"
