# Recent Developments On Blockchains

There were some developments because the prices started to go up,
so I'll introduce some of them.

Unix did it with computers, Plan 9 did it with servers, and they d
o it with networks now.

So if you have some ETH, you can lend some of the security of Ethe
reum to outside chains & apps and earn money.
Conversely, you can develop an app and buy the security of Bitcoin
to promote that your app "is secured by Bitcoin network".

Why I emphasized the term "app" is that with modular blockchains,
"smaller networks" just mean "apps".

Seriously, WTF are they doing?




## Misc

This is not technologically interesting itself, but the first Uran
ium-backed token $U has been released. You can physically exchange
1 lb of Uranium with 1 $U. So you can have Uranium and earn intere
st with it!?
