optimize transaction speed


bridge transactions take a very long time, almost 20-30 minutes per transaction, I also hear a lot of complaints from various testnet participants that their transactions are very long

maybe this will be mandatory to increase transaction speed, because the competition in crypto chains is very fierce, they all show their speed, I hope alex can fix the problem
