What is a blockchain sextet?

I'm not familiar with the term "blockchain sextet." It does not appear to be a standard term used in the blockchain or cryptocurrency industry. It is possible that it is a term coined by someone for a specific purpose or context.

A sextet is a group of six, so it might refer to a group of six entities or components related to blockchain technology. However, without more context or information, it is difficult to provide a precise definition or explanation.

If you could provide more context or clarify the source of the term, I would be happy to help you further.
