Also, it’s already used in defi, if you count that as “real world”. Reminds me of when anything on the internet wasnt “real”.
Considering how many spaces in new startups developed massive traction in that span of time (social networks, other forms of digital payments and banking, online marketplaces) the fact that there are no star products in such a span of time gives me little consideration.
There's $80 billion locked in DeFi right now. https://defipulse.com/
Uniswap has more transaction fees than the Bitcoin network https://cryptofees.info/history/2021-05-16
Institutions are even starting to get in https://twitter.com/stanikulechov/status/1394390461968633859
What has happened is defi tokens have appreciated through speculation. Sites like defi pulse erroneously represent the wealth locked into defi contracts as token_price * tokens_locked, which is trivial to manipulate for shallow-market tokens. Like, I can spin up a token with 1 billion units, buy one token for $1, and put the remaining tokens into a defi contract. Voila -- defi pulse reports $81 billion locked.
EDIT: downvotes aren't receipts, and downvoting doesn't change the accounting discrepancy.
This is what I heard when Lightning went live.
