I don't see what (real) problems any of them actually solve? Most of those are L1 blockchains and their only innovation is more tps but with plenty of other downsides like centralization. None of which are being used except to create more L2 shitcons. Development of L2 solutions like lightning completely negate any benefits of those tokens.

Ethereum has smart contracts but that's only opened the door to more scamcoins. Bitcoin can be programmed in a similar fashion with the onset of covenants. But do we really need it? Is it solving a real world problem or just coming up with an unnecessary albiet novel use case?

Ecash is a precursor implementation of bitcoin as I understand it. But it utilizes a mint which I struggle with. Seems like an inferior bitcoin to me.

Montero has privacy so I give you that. 

 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. 

 Thanks for the pointers.  Here's a few more projects that try to solve real problems that Bitcoin doesn't try to solve:

Handshake - censorship resistant DNS
Arweave - permanent web storage (aims for at least 200 years)
Chia - novel, low cost consensus mechanism 
Filecoin - low cost, decentralized storage 
Zcash - privacy 
Chainlink - Oracle services 
Nym - incentivized mixnet
Kleros - decentralized dispute resolution 
Tari - private NFT's  

 I’ve never heard of Handshake and Tari. I’ll check them out!
