TLDR of Vitalik(Ethereum blockchain Co-founder)

Vitalik recent blog post about the Ethereum application ecosystem

1. Money: the first and still most important app
In Argentina and many other countries around the world, links to global financial systems are more limited, and extreme inflation is a reality every day.
Cryptocurrency often steps in as a lifeline

2. Defi: keep it simple
-Prediction markets: these have been a niche but stable pillar of decentralized finance since the launch of Augur in 2015. Since then, they have quietly been growing in adoption.
-synthetic assets
Putting real-world assets on-chain

3. identity ecosystem: ENS, PoH, POAPs, SBTs
For a long time, I have been bullish on blockchain identity but bearish on blockchain identity platforms.
blockchains are valuable for identity applications because of their institution-independent nature.

4. DAOs
A DAO is a smart contract that is meant to represent a structure of ownership or control over some asset or process.
-DAOs to make protocol robustness, efficiency, and interoperability

5. Hybrid applications
There are many applications that are not entirely on-chain, but that take advantage of both blockchains and other systems to improve their trust models.
Voting is an excellent example.
