The blockchain technology tag is for posts relevant to blockchain, cryptocurrencies, and related topics, either as investment opportunities or as tools that could be used for achieving altruistic objectives (e.g., via mechanism design or solving coordination problems).
I also spent only ~1 minute searching for relevant posts to tag, so I’m sure I’ve missed some.
There are also at least two 80,000 Hours interviews that I think are relevant (so if someone makes linkposts of these, I think they should get this tag):
Vitalik Buterin on better ways to fund public goods, the blockchain’s failures so far, & how it could yet change the world
Radical institutional reforms that make capitalism & democracy work better, and how to get them
I wrote this description very quickly and lazily, and I don’t really know about this topic. So I encourage other people to improve the description.
