Recent issues have shown that Blockchain transactions are not truly private and users/owners have been traced by the authorities. There is metadata linked to transactions and with quantum computers being deployed there is a security risk to the platforms unless they are upgraded.
All of these issues are addressed by an upcoming project called Xx Network. It has a messenger Elixxir and software development is based on Praxxis. It is lead by one of the world famous cryptographer - David Chaum. He is credited for building the first digital cash currency in 1980s and has seen the inherent risks the current chains carry.
Are there more projects that are futuristic and are being built with widescale adoption and vision?
