Re: Blockchains and the Web of Things?

Hi Peter,
Thanks a lot for joying the discussion. You are really well positioned
to give us the clarifications on the topic ;).

I guess you have a predefined list of hashnames. Is it possible to
dynamically add/remove participants? How do you handle discovery?

Would it be fair to conclude that Telehash does *not** use blockchain
and does **not** use any form of DHT?

Agreed for JWT. Very interesting and lightweight approach.

Agreed on this also. Blockchain seems to heavy for IoT in the LPWAN context.
