Off the list I provided, only #Ethereum is expanding via L2. I named Ethereum because it’s the first blockchain that brought smart contracts enabling #Defi. Like it or not, you can’t say it’s not an innovation. Other blockchains have features/use cases not covered by #Bitcoin or are looking to scale DeFi or payments on L1.

It’s funny you mention #Lightning as a major vulnerability just got uncovered. Also, Lightning is just not Bitcoin. 

You’re looking at the wrong #eCash. Here is the one I’m referring to https://e.cash/ . It’s actually a fork of #BitcoinCash and développer by the founding #BCH team. They aim to scale P2P payment on-chain with sub-second finality. They already implemented 1-block finality. 

I haven’t said that any of these blockchains don’t have trade-off against Bitcoin. You asked for #blockhain that innovates and that’s what I provided.
