FAQ

What is SQD Network?​

SQD Network is a decentralized data lake focused on making blockchain data accessible, regardless of scale. It employs a state-of-the-art data compression and a lightweight querying engine that enables cost-efficient access to on-chain data. As of the current release of the testnet, the querying engine is being decentralized through a network of worker nodes that contribute storage and compute resources to the network, in order to serve the data in a peer to peer fashion to consumers.

How can I participate in SQD Network?​

As of the Mirovia release (June 2023), it is possible to provide infrastructure by running a worker node instance. Workers contribute storage and compute resources to the network and are rewarded with $SQD tokens.

What is a decentralized data lake?​

A decentralized data lake is a distributed system that stores and organizes large amounts of raw data in its native format until it's needed. SQD Network is an example of a decentralized data lake, providing scalable and efficient access to blockchain data.

What are some use cases for SQD’s decentralized data lake?​

SQD's decentralized data lake can be used for indexing blockchain data, powering blockchain explorers, analytics platforms, multi-chain aggregators, APIs for real-time and historical data, dApp backends and more.

Is SQD production-ready? Can I trust it for my dApp?​

Yes! SQD is production-ready and reliable for your dApp. It has been effectively used in over 500 use cases across ecosystems, proving its trustworthiness and utility within the Web3 developer community.

What are the hardware requirements to run a worker node?​

To run a single worker you will need:

  • 4 vCPU
  • 8GB RAM
  • 1TB SSD
  • public IP and one port open for incoming TCP traffic (default is 12345, but can be changed)
  • 100_000 tSQD tokens
  • Some AGOR (Arbitrum Goerli)

There are two options to run the worker:

  • using Docker
  • from sources

Please refer to this wiki for further instructions.

A single account can register multiple workers.

How do I deploy a simple squid indexer?​

Start your first squid indexer in 5 minutes! Learn more here.

What kind of datasets are available from SQD Network?​

Historical blockchain data optimized for batch access. Network API is used by Squid SDK processors to access the datasets via chain-specific gateways.

What chains are currently supported by SQD’s decentralized data lake and SDK?​

SQD Network currently supports EVM / Ethereum-compatible chains, Substrate-based chains, Solana, Fuel and Starknet (full list). More ecosystems will be integrated in the near future -- feel free to request in SquidDevs.

How can I add a new chain to be indexed by SQD Network?​

Simply reach out via this form, and we’ll get back to you as soon as possible.

I can’t code. How can I participate in SQD Network?​

As a non-coder, you will be able to participate in the SQD Network directly by delegating $SQD tokens to reliable workers to receive a percentage of the reward.

Additionally you can drive the growth of the SQD Network by helping to cultivate a vibrant community, amplifying the network's reach through social media and other platforms.

What is SQD’s roadmap?​

You can find the up-to-date roadmap here.

Does SQD Network have an app?​

Indeed, our team is hard at work developing a dedicated app for the SQD Network. The app will provide a more streamlined and user-friendly way to interact with the network. Stay tuned for updates as we get closer to its expected launch this September!

Why did SQD choose Arbitrum Goerli for the testnet?​

We have chosen Arbitrum Goerli for Arbitrum’s large community and the availability of quality tooling for smart contract deployment. We have yet to decide where we will deploy our smart contracts for the SQD mainnet.

Where is the data that SQD Network indexes stored?​

The data indexed by the SQD Network is stored in persistent storage. During the bootstrap phase, the persistent storage used by Subsquid Labs is an s3 compatible service with backups pinned to IPFS.

What is the difference between SQD Network and the Graph Network?​

Learn about the differences and see a full feature matrix here.

How does the SQD Network make blockchain data accessible for free? Are there costs involved?​

SQD Network offers the data for free to consumers while charging fixed subscription fees to chains from which the data is provided.

Of course, we can’t make the cost of hosting indexers or GraphQL free-of-charge. We invite you to consider the SQD Cloud’s simple subscription model, as well as to shop around and find the best hosting infrastructure for your project.

How does SQD ensure the security and privacy of the data accessed through the network?​

SQD Network employs validators who listen to the logs of the executed queries and resubmit them to validate the response. There's also an arbitration process to handle any discrepancies.

What is "an epoch" in the context of SQD Network?​

"Epoch" is a unit of time that SQD Network uses for internal settlement. It is defined on-chain and is currently set to be 100 L1 (Ethereum) blocks, or roughly 20 minutes.

What is Tethys?​

Tethys is the long-running testnet of SQD Network. Its contracts run on Arbitrum Sepolia. More details are available here.
