I wrote essentially the same post yesterday. The interest in crypto is directly proportional to the BTC/USD rate. I don't see real innovation compared to 2016 when very few people talked about this stuff. The single thing that has changed is the price.
- Ownership through NFTs (I personally love ENS [1]).
- Truly decentralized proof-of-stake ready for prime time, pending only the merging of the PoW network into the PoS network that launched a year ago [2].
- Predictable gas fees with EIP-1559, including a variable block size.
- A bunch of layer-2 scaling solutions live, including optimistic rollups, zero-knowledge rollups, validium solutions, and plasma solutions [3].
- Private transactions on zero-knowledge L2 chains with shielded transactions [4].
