Bitcoin Diamond is a fork of the original Bitcoin blockchain. The fork aims to improve bitcoin in two major ways: it plans to add additional encryption to each transaction, and it plans to increase the default blocksize limit to 8MB. Ultimately, Bitcoin Diamond seems to have more in common with Bitcoin Cash (BCH) than legacy Bitcoin (BTC). It’s also not totally clear who’s behind the project, how the blockchain fork works, or what type of additional encryption is being used
