# How EthStorage Works
The EthStorage network consists of two main components:
1. A storage contract deployed on the Ethereum L1 responsible for on-chain fee distribution and Proof of Storage verification.
2. An L2 storage network composed by es-nodes, responsible for off-chain data storage replicas and prove via continuous DA sampling.
This is a rough overview of how it works:
## Step 1/5
Users upload their data to an application contract, which then interacts with the EthStorage contract to store the data.
step 1/5
## Step 2/5
In the EthStorage L2 network, storage providers receive notifications about data awaiting storage.
step 2/5
## Step 3/5
Storage providers download data from the Ethereum data availability network.
step 3/5
## Step 4/5
Storage providers submit storage proof to L1, proving a substantial number of replicas in the L2 networks.
step 4/5
## Step 5/5
The EthStorage contract rewards the storage provider who successfully submits the storage proof.
