Run your client on a testnet first to help make sure everything is working correctly. Running a Geth light node should help. You need to declare any client settings that aren't default at the start. You can use flags or the config file to declare your preferred configuration. Check out your client's documentation for the specifics Client execution will initiate its core functions, chosen endpoints, and start looking for peers.

After successfully discovering peers, the client starts synchronization. Current blockchain data will be available once the client is successfully synced to the current state. Different clients have different implementations of the RPC endpoints. Applications that need information from the Ethereum network can use this RPC. For example, popular wallet MetaMask lets you run a local blockchain instance and connect to it.

By default, the RPC interface is only reachable on the localhost of your computer. To make it remotely accessible, you might want to expose it to the public by changing the address to 0. This will make it reachable over local and public IP addresses. In most cases you'll also need to set up port forwarding on your router.

You should do this with caution as this will let anyone on the internet control your node. Malicious actors could access your node to bring down your system or steal your funds if you're using your client as a wallet. A way around this is to prevent potentially harmful RPC methods from being modifiable.

For example, with geth , you can declare modifiable methods with a flag: --http. You can also host access to your RPC interface by pointing service of web server, like Nginx, to your client's local address and port. The most privacy-preserving and simple way to set up a publicly reachable endpoint, you can host it on your own Tor onion service. This will let you reach the RPC outside your local network without a static public IP address or opened ports.

To do this:. Once you restart Tor, you'll get hidden service keys and a hostname in your desired directory. From then, your RPC will be reachable on a. You should regularly monitor your node to make sure it's running properly. You may need to do occasional maintenance. Your node doesn't have to be online nonstop but you should keep it online as much as possible to keep it in sync with the network. You can shut it down to restart it but keep in mind that:. This doesn't apply on consensus layer validator nodes.

Taking your node offline will affect all services dependent on it. If you are running a node for staking purposes you should try to minimize downtime as much as possible. Consider creating a service to run your client automatically on startup.

For example on Linux servers, good practice would be creating a service that executes the client with proper config, under user with limited privileges and automatically restarts. You need to keep your client software up-to-date with the latest security patches, features, and EIPs. Especially before hard forks , make sure you are running the correct client version.

Each client implementation has a human-readable version string used in the peer-to-peer protocol but is also accessible from the command line. This version string lets users check they are running the correct version and allows block explorers and other analytical tools interested in quantifying the distribution of specific clients over the network.

Please refer to the individual client documentation for more information about version strings. Running your own node lets you use services that require direct access to Ethereum client RPC. These are services built on top of Ethereum like layer 2 solutions , consensus clients , and other Ethereum infrastructure. Clients provide metrics endpoints so you can get comprehensive data about your node.

Use tools like InfluxDB or Prometheus to create databases which you can turn into visualizations and charts in software like Grafana. There are many setups for using this software and different Grafana dashboards for you to visualise your node and the network as a whole.

As part of your monitoring, make sure to keep an eye on your machine's performance. In addition to Grafana, you can use the tools your OS offers like htop or uptime to do this. Skip to main content.

It is a bad idea to save your password to file or expose it in any other way. If you do use the --password flag with a password file, make sure the file is not readable or even listable for anyone but you.

The order of accounts when listing, is lexicographic, but as a consequence of the timestamp format, it is actually order of creation. In order to create a new account using geth, we must first start geth in console mode or you can use geth attach to attach a console to an already running instance :. The console allows you to interact with your local node by issuing commands. For example, try the command to list your accounts:. We just created our first account. If we try to list our accounts again we can see our new account:.

In fact, your first account is created during the installation of the app. The Mist wallet is still in active development, so details of the steps outlined above may change with upgrades. The Mist Ethereum wallet has an option to secure your wallet balance with a multisig wallet. The advantage of using a multisig wallet is that it requires authorization from more than one account to withdrawal larger amounts from your balance. Pick a strong yet easy-to-remember password remember there is no password recovery option , confirm it, and your account is created.

Create at least 2 accounts. Secondary accounts can be created on separate computers running Mist if you prefer and theoretically make your multisig more secure doing it this way. Your primary account will be needed to create the multisig wallet contract, so it must be on the computer you are creating the multisig wallet on.

Now that you have your accounts setup, be safe and back them up if your computer crashes, you will lose your balance if you do not have a backup. You now should add approximately no less than 0. This is required for the transaction fee when you create the multisig wallet contract.

You will be entering the full addresses of all the accounts you are attaching to this multisig wallet, when you create it. Never type an address by hand, or you run a very high risk of typos and could lose your balance sending transactions to the wrong address. We are now ready to create the multisig wallet. You will see something like this appear:.

You can send up to X ether per day. Any transaction over that daily limit requires the confirmation of X owners. Set whatever amount of owners accounts you are attaching to this multisig wallet, whatever you want for a daily withdrawal limit that only requires one account to withdrawal that amount , and how many owners accounts are required to approve any withdrawal amount over the daily limit.

You will then need to enter your password to send the transaction. When wallet creation is complete, you should see your contract address on the screen. It is also possible to access keys management from the integrated console using the built-in console or geth attach :. With it you can list, inspect, create, delete and modify keys and inspect, create and sign transactions.

We will assume you have not yet run a client such as eth or anything in the Aleth series of clients. If you have, you can skip this section. To create a wallet, run ethkey with the createwallet command:. This protects your privacy and acts as a default password for any keys.

To create a key, we use the new command. Enter a passphrase with which to secure this account or nothing to use the master passphrase. It will prompt you to enter a passphrase to protect this key. In general, you should try to use a different passphrase for each key since it prevents one compromised passphrase from giving access to other accounts. However, out of convenience you might decide that for low-security accounts to use the same passphrase. Never ever use simple passwords like this for anything else than ephemeral test accounts.

Enter a second time. The hint is stored in the wallet and is itself protected by the master passphrase. Enter the truly awful hint of backwards. Notice also that the key has another identifier after Created key. This is known as the UUID. This is a unique identifier for the key that has absolutely nothing to do with the account itself.

Knowing it does nothing to help an attacker discover who you are on the network. It reports one key on each line for a total of one key here. In this case our key is stored in a file dde Not especially easy things to remember so rather helpful that it has its proper name, test, too. In fact, you will be asked if you want to import your presale wallet during the installation of the app. Instructions for installing the Mist Ethereum wallet are given in the section Creating an account: Using Mist Ethereum wallet.

Simply drag-and-drop your. If you have a standalone installation of geth, importing your presale wallet is accomplished by executing the following command in a terminal:. You can update an existing account on the command line with the update subcommand with the account address or index as parameter. Remember that the account index reflects the order of creation lexicographic order of keyfile names containing the creation time.

The account is saved in the newest version in encrypted format, you are prompted for a passphrase to unlock the account and another to save the updated file. This same command can be used to migrate an account of a deprecated format to the newest format or change the password for an account.

For non-interactive use the passphrase can be specified with the --password flag:. Since only one password can be given, only format update can be performed, changing your password is only possible interactively.

We are now going to configure the static IP You can either do this via your router DHCP configuration or directly in the network configuration of the machine or even both. Change the interface eth0 , router address and DNS servers accordingly to your network config. The disk which has a size of Next step consists to configure fstab to automatically mount the disk when the system starts.

Geth can consume a lot of memory during the syncing process so it is highly suggested that you create a swap file overflow RAM to prevent any kind of OutOfMemory error. It is also strongly advised to put the swap file on the fastest disk, which is the SSD in our case. Before moving forward, your setup requires a very high-speed disk IO throughput.

You can test the performance of your SSD disk using the following commands:. In order to communicate correctly with other peers, Geth needs to accept connections on port from outside. You will to configure your firewall accordingly to allows for incoming requests on port to reach the machine via port-forwarding or port-triggering. To install Ethereum client Geth , we will compile it from the GitHub source. We first need to configure Geth to synchronise in fast mode using the flag --syncmode fast.

Geth also has a --cache option which specifies the amount of RAM the client can use. We want to store the Ethereum data on the SSD. See the documentation for command line options. We want to run Geth as a service and keep the process running in the background after we close the session, and be able to recover from crashes automatically.

We need to install a systemctl service systemd explanation. The following command updates the daemon list and starts Geth in the background using our service file definition. We've installed and configured Geth, so now we have to wait a few days until the sync ends. In the meantime, let me share some insights about the syncing process and what's going on under the hood. First of all, in fast sync node, the syncing process is composed of two phases running in parallel: block sync and state trie download.

Both phases need to be done in order to have a full node and switch to full mode where every transaction is executed and verified. The block sync downloads all the block information header, transactions. This phase uses a lot of CPU and space to store all the data. You can observe this process in the logs with the mention of "Importing block headers and block receipts".

However, in fast mode no transaction are executed, so we do not have any account state available ie. Geth needs to download and cross-check with the latest block the state trie. This phase is called state trie download and usually takes longer than the block sync. This phase is describes in the logs by the following statements:.

The charts below shows some metrics during the syncing process. We an observe that once the block sync has finished, we are storing less data and consuming less CPU and memory. However, Geth is still downlading and writing the state entries at a high rate. Follow this article to learn how to monitor Geth with GoogleSheet. Between 64 and blocks behind After you finished the block sync phase and during the state trie download phase, the block number count will always oscillate between 64 and block behind the latest block mined on Ethereum.

This is normal until the state trie download phase ends and your node is fully synced. After exactly 3 days, 23 hours and 49 minutes we observed the transition from fast mode to full mode:. The website ethstats retrieves the latest state of the Ethereum mainnet in real time and we can compare to see if we are synced. In conclusion, this article shows how simple and affordable it is to run a full-node on the Ethereum mainet and contribute to the good health of the network.

This guide began from a discussion about how hard it is to keep an Ethereum node stable and synced on a Single-Board Computer. So thank you for the interesting discussions and for your help in the last few weeks to make this experiment a success! Here is a summary of the different options available to synchronise the Ethereum blockchain with Geth Go-Ethereum : Blockchain sync mode [ --syncmode ]: full sync : A full sync downloads all the data block headers and block bodies , processes the entire blockchain one link at a time, and replays all transactions that ever happened in history transaction processing and PoW verification.

Here are some examples: You will own a trusted Ethereum stack you can rely on to manage your assets and send transactions to the network yourself remote nodes are generally reliable but are controlled by 3rd parties and typically throttle heavy usage. You can help secure the network; the more independent nodes running the more copies there are of the blockchain and the more resilient it is.

You want to make the network faster and more secure; the more nodes the lower the latency in sharing blocks and the more copies of the blockchain that exist. It is fun! A case to protect the board. Raspbian is a Debian-based computer operating system for Raspberry Pi. Buster Lite is a minimal version of Raspbian that doesn't contain a Desktop or Recommended software.

We can start from a very clean, light and fresh install using this version. As the sync continues, you may check on the progress of the synchronization, attach to the geth node via the built-in JavaScript console and issue the syncing command:. The way it works as described here is multiple phased:. Phase 1: Instead of starting from the genesis block and reprocessing all the transactions that ever occurred which could take weeks , fast sync downloads the blocks, and only verifies the associated proof-of-works.

Downloading all the blocks is a straightforward and fast procedure and will relatively quickly reassemble the entire chain. Phase 2: State Trie Download: Many people falsely assume that because they have the blocks, they are in sync. Unfortunately this is not the case, since no transaction was executed, so we do not have any account state available ie. These need to be downloaded separately and cross checked with the latest blocks.

This phase is called the state trie download and it actually runs concurrently with the block downloads; alas it take a lot longer nowadays than downloading the blocks. Options that can be passed to geth at startup are listed here. One using an interactive console, and the other using the web3 library which allows us to run scripts. Attaching a console simply allows us to interact with Geth from the command line.

Use the command below to attach your console to the running geth node:. From here, we can issue any number of commands to our node and have a result output. An alternative way of interacting with our node is to use a web3 package in a custom script.
