How EthStorage Works
Step 1/5
Users upload their data to an application contract, which then
interacts with the EthStorage contract to store the data.

How EthStorage Works
Step 2/5
In the EthStorage L2 network, storage providers receive
notifications about data awaiting storage.

How EthStorage Works
Step 3/5
Storage providers download data from the Ethereum
data availability network.

How EthStorage Works
Step 4/5
Storage providers submit storage proof to L1, proving a substantial
number of replicas in the L2 networks.

How EthStorage Works
Step 5/5
The EthStorage contract rewards the storage provider
who successfully submits the storage proof.

Core Features of EthStorage

01
Programmable Large KV StoreSmart contract programmable CRUD for large-value reads/writes with ~ PB capacity.
02
Proof of Storage on Large Dynamic DatasetsUse random sampling and dynamic data sharding to prove data retention and encourage re-replication.
03
High Replication Guarantee EthStorage incentivizes storage providers by using ETH as the storage fee and ensures a large number of replicas in the layer 2 network.
04
web3:// Access ProtocolDecentralized access to dynamic web objects hosted by smart contracts and EthStorage. Visit Web3URL for more details.
05
Proof of Publication via Data AvailabilityIncrease data upload speed using KZG commitment and Reed-Solomon code powered by Danksharding.
06
ETH CompatibleUsers and developers can reuse various tools from the Ethereum ecosystem, including Metamask, Solidity, Hardhat, and more.
