Is downloading bitcore – 100GB! – part of the process? Is this the blockchain that will reside on my computer? So how does it fit on mobile phones?
Hey Rob, you’re absolutely right.
If you use Bitcoin Core (i.e. a full node) you will need to download the whole Blockchain to your device. Mobile phones use SPV wallets that don’t download all of the blockchain but only a critical portion of it and rely on full nodes to verify transaction. More information can be found on our latest Bitcoin whiteboard Tuesday episode.
