Hello,
I have only a little knowledge about these scaling solutions so I want to ask if it's possible to somewhat combine these two solutions. Like, change the transaction protocol according to SegWit to allow off-chain solutions (Lighting Network) while letting the miners choose a size of the block. Is this possible?
Miners can and already and do set the size of the block with soft limits , users set the upper end of the hard limit though . Giving miners control of the blocksize would centralize mining , set a bad precedent that the miners control validation rules and not economic users, and not account for externalities like the cost of nodes on processing the blocks leading to node drop off and centralization. Essentially creating paypal 2.0 with a mining cartel , where everyone eventually is forced to trust third parties instead of validating their own txs.
So , no thank you.
What is your very balanced counter offer ? SW + 2nd layer where 2nd layer will turn out to be the very same you not want?
