SQD Network

The decentralized
data layer

2,000+ worker nodes storing over 1.5 PB of blockchain data across 225+ networks. Fully operational, open source, permissionless.

SQD Network Dashboard showing worker nodes, APR rates, and network statistics

A permissionless network of 2,000+ nodes powering blockchain data for the entire ecosystem. Not a single server behind an API key. Not a managed service you can't inspect. An open, decentralized data lake anyone can contribute to, verify, or build on.

Network at a glance

Live metrics from the SQD Network mainnet.

Built different by design

Not another centralized API with a decentralization label. These properties are structural.

Permissionless

No gatekeepers. Anyone can run a node, stake tokens, or query the network without approval.

Verifiable

All data is stored as immutable Parquet files. Every byte can be independently verified by any participant.

Revenue-Backed

Portal Pools distribute real USDT revenue from enterprise customers, not just token emissions. Demand drives rewards.

Redundant

2,000+ nodes ensure data availability. No single point of failure, no downtime from individual node outages.

Open Source

Every component (worker software, Portal, smart contracts) is open source and auditable.

Battle-Tested

Petabytes of blockchain data across 225+ networks, serving millions of queries daily in production.

How the network works

Data flows from blockchains through worker nodes and Portal to your application. Revenue flows back through Portal Pools to stakers and workers.

Five ways to join the network

Run infrastructure, stake tokens, or consume data, every role earns or benefits.

Run a Worker

Operate a worker node that ingests, validates, and stores blockchain data as immutable Parquet files. Earn SQD rewards for uptime and data served.

Worker Docs →

Delegate to Workers

Stake SQD tokens to high-performing worker nodes and earn a share of their rewards. No hardware required, just pick your workers.

Start Delegating →

Stake in Portal Pools

Lock SQD to back Portal capacity. Earn USDT from enterprise customer fees, up to 50% distributed to stakers, the rest to workers and buyback.

Run a Portal

Soon

Operate your own streaming access point to the decentralized data lake. Self-host the same open-source Rust code used in production.

Coming Soon →

Query the Data

Use the Portal API to stream blockchain data into your indexer, dApp, or analytics pipeline. 225+ networks, one endpoint, zero egress.

What's next

Four capabilities that will reshape how the world accesses blockchain data.

SQL Query Engine

Moonshot

Query the entire decentralized data lake with standard SQL. Powered by a custom DuckDB extension that fans out queries across 2,000+ worker nodes.

SELECT token, SUM(value) FROM sqd.ethereum.transfers
WHERE block > 19000000 GROUP BY token

Self-Hosted Portal

Run your own Portal instance for any chain, even ones we don't support yet. Plug in your RPCs, index the data yourself, and integrate directly into your pipeline.

Custom RPCs Self-index Any chain Open source

Private & Structured Datasets

Go beyond raw blockchain data. Define custom, structured datasets, decoded events, aggregated metrics, domain-specific tables, and run dedicated private Portal instances.

AI Agent Access

The entire Portal API is accessible to AI agents via MCP. Agents can query onchain data, build indexers, and deploy data pipelines, all through natural language.

Frequently asked questions

What is the SQD Network?
The SQD Network is the decentralized data layer that powers SQD Portal. Independent worker nodes ingest, validate, and store blockchain data from 225+ networks as immutable Parquet files. The Network is permissionless, open-source, and economically secured by the SQD token. Any developer can read data from the Network through the Portal, and any operator can run a worker.
How do worker nodes get paid?
Workers earn SQD token rewards for uptime, data served, and validation work. Reward distribution is onchain and proportional to verified contribution. Token-holders can also delegate SQD to workers and earn a share of those rewards without operating hardware. See the Network documentation for the full economic model.
Is the SQD Network decentralized?
Yes. Worker nodes are operated by independent participants across multiple jurisdictions, with no central party able to censor or restrict access to data. The validation pipeline is cryptographic and verifiable onchain. Source code for the worker software, Portal, and SDK is open. Compared to centralized RPC and indexing providers, this removes single-vendor risk for production indexers.
What is the SQD token used for?
The SQD token has three onchain uses. Workers receive SQD as reward for serving data. Delegators stake SQD on workers to earn a share of those rewards. Portal capacity is backed by SQD locked in Portal pools, with stakers earning USDT from enterprise Portal fees. The token is the economic security and incentive layer for the Network.
How does data validation work on the Network?
Each block is validated through a cryptographic pipeline before it is finalized in the Network data lake: Merkle-Patricia trie rebuild, bloom-filter verification, receipt hash validation, and state root verification. Worker nodes independently fetch, decode, and check data, and cross-check each other before finalization. This is structurally more resistant to silent data corruption than reading from a single RPC provider. Full details are in the SQD documentation.
