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. Plug the power to the Raspberry Pi as well as an Ethernet cable 8. Determine its IP address default hostname of the machine is raspberrypi Your network router should provide the list of all the connected devices via Ethernet and WIFI.

Example - VirginMedia Hub 9. Connect via SSH with default user pi and enter the default password raspberry We enabled ssh by default during step 5, so it is possible to connect remotely via SSH from a Linux terminal or using Putty if you use Windows to the system. SSH is enabled and the default password for the 'pi' user has not been changed. This is a security risk - please login as the 'pi' user and type 'passwd' to set a new password.

Change the hostname The default hostname attributed by Raspbian is raspberrypi , this can cause confusion if you have multiple devices, so it's recommended to rename the machine with a more specific hostname related to its purpose.

Upgrade the OS Upgrade the system in order to get the latest patches. Example - VirginMedia Hub b. Reboot Reboot the machine and log in with the static IP and the new password. Find the disk name drive Run the command fdisk -l to list all the connected disks to the system includes the RAM and try to identify the SSD.

Ensure that the version of Geth is the same as the one installed on your RPi. If not, upgrade your nodes. When you start Geth like that, without any command line argument, it immediately starts synchronizing with the main chain, which takes several days.

At this stage, Ethereum is installed on your computer and able to synchronise with the live chain mainnet. Part 3 describes how to setup a private chain and a miner node. Hi Said!! A really good tutorial!! You might know how can I do? Thanks for your feedback. The instructions above worked on my Mac, however when I tried them on my Ubuntu machine they did not.

I have now one node on raspberry pie. Raspberry Pie is connected now via Ethernet. I connect to Raspberry Pie via terminal using It works. I have created a runnable script to start my nodes like startnode1. INFO [ WARN [ The tutorials are great and I thank you for putting these up in detail. Please let me know how to proceed from here.
