If you are semi-experienced hive user or even a very experienced one, this quick tutorial video will demonstrate how easy it is to send encrypted messages on the blockchain. The memo field is an incredibly useful tool and I would suggest becoming familiar with this feature on not just hive, but other blockchains as Layer 2 Blockchain is phased in and we proceed onto the development of Layer 3 blockchain technologies.
In order to view the encrypted memo field, the recipient will need to sign into hive with their private memo key.
If you have any questions feel free to ask them below and I will b happy to assist.
