How does Coinbase work?
Coinbase runs its own digital currency nodes that communicate with the rest of the network. When you initiate a transaction, we broadcast it to the rest of the network so it can be confirmed. Our nodes may lose sync with the rest of the network for short periods of time, which can cause transactions to remain Pending longer than normal.
