@vandys @lupyuen proper use of a blockchain requires so much network effect, 99% of "blockchains" out there are not secure at all and might as well be centralized, unless they use #bitcoin or ethereum, replacing anything with a blockchain is pointless (and really anything other than bitcoin...)

In case any of you missed it, podcastindex.org has adopted a blockchain to replace its endless polling of RSS feeds. A number of podcast hosting sites will now push out new episodes as transactions on the chain. So the servers behind podcastindex.org don't polll those sites any more, they just watch the transactions.

@lupyuen Neat, I'm a bit on the fence with FreeRTOS and have been wanting to give NuttX a go, being more familiar with #ESP32 hardware (and have designed a bunch) this would be a great nudge.
