Storage Provider Tutorial
This guide provides practical steps for the storage providers to start an es-node instance for connecting to one of the existing EthStorage networks.
This tutorial targets EthStorage deployments on Ethereum L1 (Mainnet and Sepolia) and QuarkChain L2 testnet. Some steps differ among the three networks, and the variant of each shell command is provided.
If you simply need to upgrade your es-node instance to a newer version, please refer here.
Before Starting
Minimum Hardware Requirements
CPU: A minimum of 4 cores and 8 threads
8 GB of RAM
Disk:
We recommend using an NVMe disk to support the full speed of sampling
At least 550 GB of available storage space for the runtime and sync of one data shard
Internet: At least 8 MB/sec download speed
System Environment
macOS Version 14+, Ubuntu 20.04+, or Windows with WSL (Windows Subsystem for Linux) version 2
(Optional) Docker 24.0.5+ (would simplify the process)
(Optional) Go 1.23+ and Node.js 16+ (can be installed following the steps)
ℹ️ Note: The steps assume the use of the root user for all command line operations. If using a non-root user, you may need to prepend some commands with "sudo".
Preparing miner and signer account
We recommend preparing two specific Ethereum accounts to run an es-node.
The miner account will be set to receive rewards once the storage provider successfully submits a storage proof to the EthStorage contract. Each storage provider must use a unique miner account on the same network.
The signer account signs transactions and must hold sufficient ETH for gas. If you run multiple es-nodes on the same network, use a separate signer account per node to avoid nonce conflicts.
ℹ️ Note: If Sepolia is used as L1, request test ETH from sepoliafaucet.com; for QuarkChain L2 testnet, get custom gas tokens here.
⚠️ Warning: For safety reasons, we strongly suggest creating new wallets for the accounts to avoid the loss of any personal assets.
Remember to use the signer's private key (the one with ETH balance) to replace <private_key>
in the following steps. And use the other address to replace <miner>
.
Preparing Ethereum API endpoints (L1 only)
During the operation of es-node that deployed on L1, frequent Ethereum API calls are made, including at the execution layer and the consensus layer (the beacon chain). Therefore, we need you to prepare endpoints for two types of calls. We recommend using BlockPI
for the execution layer endpoint and QuickNode
for the beacon endpoint.
For details on the application process for endpoints, please refer to this section.
In the following tutorial, you will need to replace <el_rpc>
for your execution layer endpoint, and <cl_rpc>
for the beacon endpoint.
ℹ️ Note: You do not need to apply Ethereum API endpoints to run es-node for the QuarkChain L2 network.
Options for running es-node
You can run es-node from a pre-built executable, a pre-built Docker image, or from the source code.
If you choose the pre-built es-node executable, you may need to install Node.js if using default zk prover implementation.
If you have Docker version 24.0.5 or above installed, the quickest way to get started is by using a pre-built Docker image.
If you prefer to build from the source code, you will also need to install Go besides other dependencies.
From pre-built executables
Before running es-node from the pre-built executables, ensure that you have installed Node.js and snarkjs (unless --miner.zk-prover-impl
flag is set to 2
).
ℹ️ Note: Ensure that you run the executables on WSL 2 if you are using Windows, and both Node.js and snarkjs are installed on WSL instead of Windows.
Download the pre-built package
Choose the one that is suitable for your platform:
Linux x86-64 or WSL:
curl -L https://github.com/ethstorage/es-node/releases/download/v0.2.4/es-node.v0.2.4.linux-amd64.tar.gz | tar -xz
MacOS x86-64:
curl -L https://github.com/ethstorage/es-node/releases/download/v0.2.4/es-node.v0.2.4.darwin-amd64.tar.gz | tar -xz

After launch, you can check docker logs using the following command:
docker logs -f es
Mount data location using Docker volume option
Docker volumes (-v) are a mechanism for storing data outside containers. In the above docker run
command, you have the flexibility to modify the default data file location (./es-data
) on your host machine, ensuring that the disk space requirements are fulfilled. For example:
docker run --name es -d \
-v /host/path/with/large/space:/es-node/es-data \
...
ℹ️ Note: The absolute host path does not function well on Windows, for more details please refer here.
From source code
You will need to install Go to build es-node from source code.
Just like running a pre-built, if you plan to utilize the default zkSNARK implementation, ensure that you have installed Node.js and snarkjs.
If you intend to build es-node on Ubuntu and use rapidsnark
as zkSNARK implementation, be sure to verify some dependencies.

Applying for Ethereum API
ℹ️ Note: The steps below describe applying for Sepolia endpoints. For Ethereum Mainnet, the process is similar—choose Mainnet where applicable and follow provider-specific details.
Applying for a free Sepolia execution layer endpoint from BlockPI
Go to the BlockPI website, click Get Started
. After signing in, you will get your Free Package Gift
. Click Generate API Key
, and remember to select Sepolia
, and you will get your API endpoint.
Finally, access the detailed page of your API endpoint and activate the Archive Mode
under the Advanced Features
section.
ℹ️ Note: The free plan of BlockPI provides sufficient usage as execution layer RPC for es-node, but it cannot be used as a beacon endpoint.
Applying for a free Sepolia beacon endpoint from QuickNode
Go to the QuickNode website, click Get started for free
. After signing in, you can create an endpoint. Remember to select Ethereum
and Sepolia
to continue. In the Compliance & Safety
category, select Endpoint Armor
, and select the free plan. After completing the required information, you will receive the endpoint along with an API key.
ℹ️ Note: The free plan of QuickNode is adequate for use as a beacon endpoint (<cl_rpc>) for running es-node, but is NOT sufficient as execution layer endpoint.
Install dependencies
ℹ️ Note: Not all steps in this section are required; they depend on your choice.
Install Go
Download a stable Go release, e.g., go1.23.7.
curl -OL https://golang.org/dl/go1.23.7.linux-amd64.tar.gz
Extract and install
tar -C /usr/local -xf go1.23.7.linux-amd64.tar.gz
Update $PATH
echo "export PATH=$PATH:/usr/local/go/bin" >> ~/.profile
source ~/.profile
Install Node.js
Install Node Version Manager
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.3/install.sh | bash
Close and reopen your terminal to start using nvm or run the following to use it now:
export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion" # This loads nvm bash_completion
Choose a Node.js version above 16 (e.g. v20.*) and install
nvm install 20
Activate the Node.js version
nvm use 20
Install snarkjs
npm install -g snarkjs
Install RapidSNARK dependencies
Check if build-essential
and libomp-dev packages
are installed on your Ubuntu system:
dpkg -l | grep build-essential
dpkg -l | grep libomp-dev
Install the build-essential and libomp-dev packages if no information printed:
apt update
apt install build-essential
apt install libomp-dev
Install libc6_2.35
This installation is intended for scenarios where you encounter errors like this while running the pre-built es-node on Ubuntu 20.04:
/lib/x86_64-linux-gnu/libc.so.6: version 'glibc_2.32' not found
/lib/x86_64-linux-gnu/libc.so.6: version 'glibc_2.34' not found
To prevent the error, add the following line to your /etc/apt/sources.list:
deb http://security.ubuntu.com/ubuntu jammy-security main
Next, install libc6_2.35 by running the following commands:
apt update
apt install -y libc6
Check the status after launching the es-node
It's important to monitor the node closely until it successfully submits its first storage proof. Typically, the process encompasses three main stages.
Data sync phase
The es-node will synchronize data from other peers in the network. You can check from the console the number of peers the node is connected to and, more importantly, the estimated syncing time.
During this phase, the CPUs are expected to be fully occupied for data processing. If not, please refer to the FAQ for performance tuning on this area.
A typical log entry in this phase appears as follows:
INFO [01-18|09:13:32.564] Storage sync in progress progress=85.50% peerCount=2 syncTasksRemain=1@0 [email protected] blobsToSync=0 fillTasksRemain=30 emptyFilled=3,586,[email protected] emptyToFill=608,127 timeUsed=1h48m7.556s eta=18m20.127s
Sampling phase
Once data synchronization is complete, the es-node will enter the sampling phase, also known as mining.
A typical log entry of sampling during a slot looks like this:
INFO [01-19|05:02:23.210] Mining info retrieved shard=0 LastMineTime=1,705,634,628 Difficulty=4,718,592,000 proofsSubmitted=6
INFO [01-19|05:02:23.210] Mining tasks assigned shard=0 threads=64 block=10,397,712 nonces=1,048,576
INFO [01-19|05:02:26.050] Sampling done with all nonces samplingTime=2.8s shard=0 block=10,397,712
When you see "Sampling done with all nonces", it indicates that your node has successfully completed all the sampling tasks within a slot. The "samplingTime" value informs you of the duration, in seconds, it took to complete the sampling process.
If the es-node doesn't have enough time to complete sampling within a slot, the log will display "Mining tasks timed out". For further actions, please refer to the FAQ.
Once data sync is finished, you will receive an email notification indicating which shard has been started mining, if email notifications have been enabled on your es-node.
Proof submission phase
Once the es-node calculates a valid storage proof, it will submit the proof to the EthStorage contract and receive the rewards.
A typical log entry of submitting proof looks like this:
INFO [01-19|05:02:23.210] Calculated a valid hash shard=0 thread=3 block=5,437,371 nonce=58101
INFO [01-19|05:05:23.210] Mining transaction confirmed" txHash=0x7afa13e5211c403a7024bdf0a6880203d54698355679be9aab1aa0ecef78eecd
INFO [01-19|05:05:23.210] Mining transaction success! √ miner=0xBB9D13efa21c0a053eCFE622e2AbfAF0D7573f50
Once you see this log, congratulations on completing the entire process as a storage provider. You can also check how many storage proofs you've submitted, your ETH profit, and your ranking on the dashboard.
Once a valid proof has been submitted, you will receive an email notification with the detailed information, if email notifications have been enabled on your es-node.
Advanced Features
About run*.sh
and init*.sh
run*.sh
and init*.sh
The run*.sh
scripts serves as the entry point for launching the es-node with predefined parameters. By default, mining is enabled through the --miner.enabled
flag in run*.sh
, which implies that you assume the role of a storage provider upon starting an es-node with the default settings.
However, before the es-node can be successfully launched, you must execute init*.sh
first. The primary function of this script is to verify the system environment, download and install dependencies, and initialize the data files in preparation for mining.
For specific usage and examples of the two scripts, refer to the steps outlined in Options for running es-node.
ℹ️ Note: By default,
init.sh
andrun.sh
target Sepolia; useinit-mainnet.sh
/run-mainnet.sh
for Ethereum Mainnet andinit-l2.sh
/run-l2.sh
for QuarkChain L2.
This applies to every shell command throughout the rest of this guide.
ℹ️ Note: Some of the flags/parameters used in the shell scripts are supposed to change over time. Refer to configuration for a full list.
Mining multiple shards
By default, only the first shard (shard 0) is mined using the default options in the scripts, but you have the choice to initialize and run your es-node in order to mine multiple selected shards by using additional options.
Take Sepolia network as example, the flag --shard_index
can be utilized multiple times with init.sh
to generate data files for multiple shards on the es-node. For example,
env ES_NODE_STORAGE_MINER=0x123...ab ./init.sh --shard_index 1 --shard_index 2
Please take note of the following:
The shard files will be generated in the
./es-data
directory with the naming conventionshard-$(shard_index).dat
by default settings ininit.sh
.A shard will be omitted if its corresponding data file already exists.
shard-0.dat
will be tried to create if no--shard_index
is specified.For Mainnet, use
init-mainnet.sh
to replaceinit.sh
; for QuarkChain L2, useinit-l2.sh
.
After initialization in this way, the run.sh
script will attempt to operate on data files located in ./es-data/shard-*.dat
. If you have relocated these data files or added additional files in another location, you can specify them using the --storage.files
options repeatedly following ./run.sh
.
About the option of zk prover implementation
The --miner.zk-prover-impl
flag specifies the type of zkSNARK implementation. Its default value is 1
, indicating the generation of zk proofs using snarkjs. The option 2
means to utilize go-rapidsnark. Since --miner.zk-prover-impl
interacts closely with the environment, it is crucial to use the same configuration when running both init.sh
and run.sh
.
ℹ️ Note: If you have to run an es-node pre-built with
--miner.zk-prover-impl 2
on Ubuntu 20.04, you will need to install extra packages.
