Whose computers does bitcoin use to confirm transactions
WHO confirms a Bitcoin transaction?
For a public blockchain, the decision to add a transaction to the chain is made by consensus.

The people who own the computers in the network are incentivised to verify transactions through rewards.

The proof-of-work algorithm used by Bitcoin aims to add a new block every 10 minutes. To do that, it adjusts the difficulty of mining Bitcoin depending on how quickly miners are adding blocks.

Is XRP a PoW?
How Ripple Works. The Ripple network does not run with a proof-of-work (PoW) system like bitcoin or a proof-of-stake (PoS) system like Nxt. Instead, transactions rely on a consensus protocol in order to validate account balances and transactions on the system.
