Put aside for a moment the name for the 'scheme' and consider the mechanism design differences between USD and Bitcoin: - USD is needed in order to pay taxes on the US, but can be …

I think the reference to retirement funds is in relation to the fact many of them are under collateralized. They need to take new investor's money to pay out old investors. Some mo…

Hey dweller! That isn't the mechanism. What happens instead is akin to an endowment for payment of storage. An outline is found here: https://www.arweave.org/faqs.html#what-is-a-st…

Thanks for the comment @blacksqr! This calculator is outdated -- the current price of storage oscillates around $0.01/MB. The maximum single chunk size is also 10MB now, and you ca…

Ah, thanks. That makes sense.

This is very neat! I created an Erlang script that allows you to send messages by morse code to the keyboard like this: ./remote_morse "HI,IAMSAM." (Spaces don't appear to be used …
