Question 1

How to set up a self-hosted DB3 Network node?

Accepted Answer

Run the Docker command from the README, then access the console at localhost ports to configure databases and collections. The process involves multiple steps, including setting admin addresses and visiting specific URLs for setup.

Question 2

DB3 Network vs MongoDB for Web3 applications?

Accepted Answer

DB3 Network offers decentralized storage and data permanence via Arweave rollups, ideal for owner-controlled Web3 apps, while MongoDB is centralized and better for traditional, high-performance use cases without blockchain integration.

Question 3

Can I recover data if a DB3 node fails?

Accepted Answer

Yes, by running your own Data Index Node, you can recover data from the blockchain and Arweave, as the architecture separates rollup and index nodes for tamper resistance and recovery.

Question 4

What does it cost to use DB3 Network with Arweave?

Accepted Answer

The README mentions very low cost for Arweave rollups, but specific expenses depend on Arweave storage fees and network usage. For accurate pricing, monitor Arweave's rates and DB3's documentation updates.

Question 5

How does DB3 handle query performance for large datasets?

Accepted Answer

Data Index Nodes provide queryable APIs, but performance may be impacted by node resources and network conditions. Self-hosted nodes with adequate hardware are recommended for optimal query speeds.

Question 6

Is DB3 Network good for real-time apps like multiplayer games?

Accepted Answer

Not ideally, due to periodic rollups to Arweave introducing latency. For real-time needs, consider the trade-off between data permanence and update frequency.
