- increased capacity of txs/second
- reduced size of blockchain
- ability to re-transmitting tx if the fee is insufficient (adding/increasing fee after tx was done).
If all that was done on the level of blockchain, without any sidechains etc I'd be pretty happy.
Agree with this. but for me the most important is fast confirmations and increased capacity of txs/second. because i'm gambler need fast confirmations
How fast would be enough for purposes such as gambling? There are reasons why confirmations are not instant. But I agree, 10 min is probably too long these days.
