Subsquid is not a blockchain itself but rather a blockchain indexing and querying framework designed to efficiently process and query blockchain data. It is built on top of existing blockchains rather than being its own independent blockchain.

Key Points About Subsquid:

1. Supports Multiple Blockchains – Subsquid can index data from various blockchains, including:

   • Ethereum (via The Graph)
   • Polkadot (via Substrate-based chains)
   • Cosmos (via Tendermint-based chains)
   • Near Protocol
   • Avalanche
   • And others via custom integrations.

2. Works with The Graph – Subsquid is often used alongside The Graph, a decentralized indexing protocol, to enhance querying capabilities.

3. Not a Blockchain – Unlike Polkadot, Cosmos, or Ethereum, Subsquid does not have its own native blockchain. Instead, it provides tools to index and query data from other blockchains.

4. Used for Web3 Data Infrastructure – It helps developers build decentralized applications (dApps) by providing fast, scalable, and flexible access to blockchain data.

Summary:

Subsquid is not its own blockchain but a powerful indexing and querying framework that works on top of existing blockchains. It is particularly useful for developers building Web3 applications that require efficient data access.

Yes, Subsquid is programmable and supports the development of decentralized applications (dApps) and smart contracts, but with some important distinctions compared to traditional blockchain platforms like Ethereum or Solana.

Key Features of Subsquid for Programmability:

1. Indexing & Querying (Not Smart Contracts)

   • Subsquid is primarily an indexing and querying layer for blockchain data, not a smart contract platform.
   • It allows developers to efficiently index and query blockchain data (e.g., from Polkadot, Ethereum, Cosmos) using GraphQL and SQL.
   • It does not natively support on-chain smart contract execution like Ethereum or Solana.

2. Decentralized Applications (dApps) via Indexing

   • While Subsquid itself doesn’t run smart contracts, it can be used to build dApps that rely on indexed blockchain data.
   • Example: A DeFi analytics dashboard that fetches real-time data from multiple chains via Subsquid.

3. Custom Processing with TypeScript/JavaScript

   • Subsquid allows custom processing logic (e.g., filtering, aggregating, or transforming data) using TypeScript/JavaScript in its processors.
   • This enables developers to build off-chain logic that interacts with blockchain data.

4. Integration with Smart Contracts (Indirectly)

   • You can use Subsquid to index smart contract events (e.g., from Ethereum, Polkadot, or Cosmos) and then build off-chain applications that interact with those contracts.
   • Example: A dApp that fetches NFT metadata from a smart contract and displays it in a custom UI.

Comparison with Smart Contract Platforms:

Feature	Subsquid	Ethereum / Solana
Smart Contracts	❌ No	✅ Yes
On-Chain Execution	❌ No	✅ Yes
Indexing & Querying	✅ Yes	❌ (Requires The Graph)
Off-Chain Processing	✅ Yes	❌ (Possible but not native)

Use Cases for Subsquid:

• Blockchain Analytics (e.g., tracking DeFi protocols)
• NFT Metadata Indexing (e.g., fetching NFT traits from smart contracts)
• Cross-Chain Data Aggregation (e.g., combining data from Ethereum, Polkadot, and Cosmos)
• Custom Data Processing (e.g., filtering and transforming blockchain events)

Conclusion:

Subsquid is not a smart contract platform like Ethereum or Solana, but it is highly programmable for indexing, querying, and processing blockchain data. If you need on-chain smart contracts, you should use a blockchain like Ethereum, Solana, or Polkadot, and then use Subsquid to index and query that data.

Subsquid is a decentralized data indexing and querying protocol designed for blockchain data, primarily used to build high-performance APIs for Web3 applications. However, it's important to clarify that Subsquid itself does not process transactions like a blockchain—it indexes and queries data from blockchains (e.g., Ethereum, Polkadot, or other supported chains).

Transaction Confirmation Time & Throughput

Since Subsquid operates as an indexing layer, its performance depends on the underlying blockchain it indexes from. Here’s a breakdown:

1. Confirmation Time (Latency)

   • Subsquid typically processes new blocks within seconds of their finalization on the source chain.
   • For example, if indexing Ethereum, Subsquid can query new blocks shortly after they are confirmed (usually within 10–30 seconds).
   • For Polkadot or other chains, the latency depends on the chain's finality time (e.g., ~6 seconds for Polkadot).

2. Throughput (Transactions Per Second - TPS)

   • Subsquid does not have a fixed TPS because it is not a transaction-processing network.
   • Instead, it scales with the throughput of the indexed blockchain.
   • For example:
     • Ethereum (Post-Merge): ~15–30 TPS (varies with congestion).
     • Polkadot: ~1,000 TPS (theoretical max, but real-world throughput is lower).
   • Subsquid can handle thousands of queries per second for indexed data, depending on the database and query complexity.

Subsquid’s Own Network (If Applicable)

If you're referring to Subsquid’s decentralized network (which is still in development), its performance will depend on:

• Consensus mechanism (likely PoS or similar).
• Node participation (more nodes = higher throughput).
• Optimized indexing algorithms (likely designed for low-latency queries).

Conclusion

• For indexing existing blockchains: Subsquid processes data within seconds of block finality.
• For its own network (future): Expected to be optimized for high throughput and low latency, but exact numbers are not yet finalized.

Would you like details on a specific blockchain integration (e.g., Ethereum, Polkadot, etc.)?

Subsquid is not a blockchain itself but rather a data indexing and querying framework designed to work with various blockchains (like Polkadot, Ethereum, and others). It specializes in off-chain data storage and indexing, allowing developers to efficiently query blockchain data without relying on on-chain storage.

Does Subsquid Support On-Chain Data Storage?

No, Subsquid does not provide on-chain storage. Instead, it focuses on:

• Indexing blockchain data (e.g., events, state changes) into a PostgreSQL database for fast querying.
• Storing processed data off-chain for analytics, APIs, and applications.
• Supporting GraphQL and REST APIs for easy data access.

How Much Data Can You Store?

Since Subsquid relies on off-chain databases (like PostgreSQL), the storage capacity depends on:

• Your database infrastructure (e.g., cloud storage, self-hosted servers).
• The blockchain you're indexing (e.g., Ethereum, Polkadot, Cosmos).

There is no hard limit imposed by Subsquid itself—you can scale storage as needed.

Alternatives for On-Chain Storage

If you need on-chain storage, consider:

• IPFS + Filecoin (for decentralized file storage).
• Arweave (permanent storage).
• Blockchain-specific storage solutions (e.g., Ethereum’s storage slots, Polkadot’s StorageMap).

Conclusion

Subsquid is great for off-chain data indexing and querying, but if you need on-chain storage, you’ll need to use other solutions. Would you like recommendations based on your specific use case?
