DB3 Network is an open-source, decentralized firebase firestore alternative to build dApps quickly with minimal engineering effort.
Currently, there are two types of Data architecture for dApp(decentralized application): centralized vs. decentralized.
Centralized: use Firebase
Decentralized: use Ethereum
With Db3 network, you can get both advantages of the above two choices.
Schemaless
You can store data on DB3 Network without any changes.
High Performance
Currently, decentralization means terrible performance, but DB3 is trying to improve it significantly:
- Merkdb is the storage engine of the DB3 Network, and it has high Performance and fast-proof generation.
- Geo distribution: the nodes in every storage shard are geo-distributed, and the clients can execute queries against the nearest storage node.
- Query session, the first decentralized query protocol to resolve Performance and incentive perfectly.
Data Ownership
We proposed the document level ownership, and every document has its owner, while only the owner holds the private key can update/delete the record. DB3 network generates the proofs and provides signatures to prove the membership (db3 has the specific document) and ownership.
Programmable
Dapp developers can develop data processing contracts and deploy them to the DB3 Network, just like the data backend in web2.
Ethereum Guarded Security
DB3 Network is a layer2 network on Ethereum and Ethereum guards all the assets.

- Add a GitHub Star⭐️ to the project.
- Tweet about how to use DB3 network.
- Write blogs about the project on Dev.to, Medium or your personal blog.
Together, we can make db3 network better!
- the graph, a decentralized on-chain indexer
- Locutus, a decentralized key-value database
- ceramic network, a decentralized data network that brings unlimited data composability to Web3 applications
- kwil, the first permissionless SQL database for the decentralized internet
- spaceandtime, a decentralized data Warehouse
- OrbitDB is a serverless, distributed, peer-to-peer database
I stood on the shoulders of giants and did only simple things. Thank you for your attention.
