Is there any ETA you are aware of my friend about payment channels and Schnorr sigs ?
Payment channels - soon
Schnorr - nobody knows
Some people believe there's benefit in the ability to do 2 of 2 ed25519/secp256k1 multisig transactions to try and bulletproof wallet security, so I'm not really sure all the implications there.
To be honest, I didn't didn't dig into those two features you've just mentioned.
But what caught me is "bulletproof" the wallets and I think this is extremely important.
Don't forget after we successfully finish the block size debate, there are more to come, anon., security and ... etc.
