The Monero daemon `monerod` keeps your computer synced up with the Monero network.
It downloads and validates the blockchain from the p2p network.
## Not aware of your private keys
`monerod` is entirely decoupled from your wallet.
`monerod` does not access your private keys - it is not aware of your transactions and balance.
This allows you to run `monerod` on a separate computer or in the cloud.
In fact, you can connect to a remote `monerod` instance provided by a semi-trusted 3rd party. Such 3rd party will not be able to steal your funds. This is very handy for learning and experimentation.
However, there are privacy and reliability implications to using a remote, untrusted node. For any real business **you should be running your own full node**.
