speed up so it means the transaction will now be faster ? thats great . now we can use more btc even in a hurry but the only downside is that it will make things centralized ?
Transactions won't become faster
I mean beyond what is specified or implied by the Bitcoin protocol, which is one block of transactions per 10 minutes (unless you are using LN or similar technology for off-chain transactions). But you probably already know that, don't you? Of course, if there's a dramatic surge in the hash rate, we will likely see a boost in the number of new blocks found, which will bring about faster confirmations as well, but this rise will soon be leveled out by the respective rise in the mining difficulty. And then we are back to square one (minus some miners having to pull the plug)
