Great video Hive account@heiditravels! There's another DAG chain cryptocurrency coming soon that's worth a look at: Yobicash.

Yobicash is a cryptocurrency based on DAG chain so doesn't have the scalability issues associated with blockchains.

Yobicash is a cryptocurrency built to secure the storage and sharing of data by ensuring the main properties of information security: confidentiality, integrity and availability. To enforce these properties, Yobicash employs cryptographic protocols, data replication, economic incentives and a DAG chain of transactions.

The cryptographic primitives and design are described by project designer Christian Nyumbayire in the Yobicash whitepaper first published in October 2017: https://yobicash.org/whitepaper.pdf

In summary, Yobicash reinforces:

privacy through zero-knowledge proof and encryption
data integrity through cryptographic authentication
data availability through replication
