If you have a Ledger Nano S hardware wallet, did you know Monero support for Ledger recently arrived in v0.12.3.0 of the GUI wallet? You can protect your Monero from hackers and malware by storing it on your Ledger, at a wallet address that is securely derived from the recovery seed of your Ledger wallet. Next to creating a paper wallet and signing transactions with an offline, air-gapped computer, this is the safest way to protect your Monero private keys. The private spend key is never revealed to the computer which you are running the Monero client on – it is stored exclusively on the secure element of your Nano Ledger S. Only the view key is shared with your PC to scan the blockchain for incoming transactions.
Using Monero with Ledger Nano S, on Windows, MacOS or Linux
Always backup your recovery seed before attempting to make changes to your Ledger device.

If you followed our previous guide how to set up your Monero node, you will eventually need to update the daemon to the latest version. Luckily it is a simple process to do, and in most cases, does not require resyncing the blockchain from scratch. First you have to understand the difference between point and major releases in the Monero project to understand the importance of staying up to date, especially with major releases.
In general, your Monero node will still be able to communicate with other nodes if you haven’t updated it after a point release (for example: 0.12.0.0 -> 0.12.1.0). It is still advisable to update as soon as practical to the latest point release, as stability & security issues are often resolved through these versions.
On the contrary, it is mandatory to update your daemon before a Monero scheduled hard fork that typically happens around every 6 months (0.11.x.0 -> 0.12.x.0). Hard forks are always announced in advance on getmonero.org and the official Monero subreddit. After the blockchain forks off to the latest version, it is deliberately not backward compatible with prior versions.

Running your own Monero node can be a challenging, yet rewarding experience that gives you a better understanding how the anonymous cryptocurrency functions to protect your financial privacy – including balances & payment information.
Like other cryptocurrencies such as Bitcoin, the Monero network comprises of full nodes that sync with other nodes (peers) to maintain a copy of the distributed ledger, rebroadcast transactions, and optionally, mine blocks to secure the network.
To use Monero, you need a “wallet” which serves as a client application that connects to either a local daemon or remote node. By default, the official Monero wallet from getmonero.org starts a local daemon when you launch the software. Before you can check the balance of an existing wallet or send funds to others, the local daemon must download a complete copy of the blockchain – a process that can take two days or more depending on the speed of your Internet connection and whether you have a SSD or not.
