Who confirms Bitcoin transactions?
I'm wondering about the process of Bitcoin transactions. Specifically, I want to know who is responsible for confirming these transactions in the Bitcoin network.
What crypto confirms the fastest?
Could you please elaborate on which cryptocurrency currently confirms transactions at the fastest rate? Are there any particular factors that contribute to this speed, such as the blockchain's consensus mechanism, transaction volume, or network congestion? Is there a specific use case or market demand that drives the development of faster confirmation times? Additionally, are there any trade-offs or potential drawbacks to prioritizing transaction speed over other factors like decentralization or security?
