[Your Project and Solution] Solution

Please describe your proposed solution and how it addresses the problem

On Cardano, building an app requires fast, reliable access to blockchain data. However, without a high-quality, seconds-from-the-chain-tip data aggregator, developers face major delays. They must:

• Run and maintain their own node infrastructure.
• Build and maintain custom pipelines to parse raw chain data.
• Handle ongoing updates as Cardano evolves.

This slows time-to-market and raises costs, especially for smaller teams. Many apps need real-time data to function (for example, DeFi protocols, NFT marketplaces, and analytics dashboards) but cannot achieve it without a robust, self-service data aggregator.

Cardano currently lacks a free, production-grade data querying service that delivers structured, SQL data within seconds of the latest block. This gap makes it nearly impossibnle for builders to launch competitive, data-driven apps quickly.

Quick video demo highlighting how easy it is to build with Space and Time’s indexed data (this is an EVM focused demo, but we are so excited to bring this tech to Cardano!): https://www.loom.com/share/ccfe6cbe67cd4dbab9a252166403b185?sid=ffc0e69a-690b-4567-b125-25c6b1cfc7c8

We propose to build a tamperproof, enterprise-grade data aggregator for Cardano, fully integrated into Space and Time’s decentralized data warehouse. This will allow developers, enterprises, and analysts to query real-time, verifiable Cardano blockchain data without running their own indexing infrastructure.

Our solution will:

• Ingest Cardano mainnet data in real-time from multiple fullnodes (we will run these ourselves and contribute to the decentralisation of the network), ensuring data is tamperproof, accurate, and up to the tip (<1 block).
• Data aggregator will capture core chain data (blocks, txns, contract event logs, transfers, balances, etc) as well as self-service indexing of devs’ individual contracts they’ve deployed.
• Store that data in Space and Time’s distributed, verifiable database, secured by our novel Proof of SQL protocol to ensure results are cryptographically tamperproof.
• Provide comprehensive REST APIs for easy programmatic access.
• Include AI-powered Prompt-to-SQL in our web app (app.spaceandtime.ai), enabling natural-language queries that generate secure, optimized SQL.
• Offer prebuilt analytics schemas covering transactions, staking, governance, tokens, and smart contracts to accelerate dApp development.
• Allow devs to operate their own open source data aggregator for free.

Note: as an enthusiastic member of the Cardano community, the Space and Time / MakeInfinite Labs team will be open sourcing the data aggregator and making it available for Cardano community devs for 3 years, with reasonable rate limits for popular app devs (enterprise tiers available for devs that go viral!).

[Your Project and Solution] Impact

Please define the positive impact your project will have on the wider Cardano community

The Cardano ecosystem will benefit from:

• A next-gen, Rust-based, open source data aggregator built for both core chain data (blocks, txns, contract event logs, transfers, balances, etc) as well as self-service indexing of devs’ individual contracts they’ve deployed.
• Devs can spin up and operate their own open source data aggregator at their discretion, or use our free rate limited APIs (hosted for the devs).
• Lower barriers to entry for developers; anyone can instantly query clean, indexed Cardano data without running or maintaining infrastructure.
• Accelerated dapp and analytics adoption; builders can focus on products instead of backend data pipelines.
• Improved transparency and trust; Space and Time (with development from MakeInfinite Labs) ensures that data and analytics can be cryptographically verified as accurate and untampered.
• AI-powered SQL; natural-language querying opens Cardano data to non-technical users, driving broader ecosystem engagement.

[Your Project and Solution] Capabilities & Feasibility

What is your capability to deliver your project with high levels of trust and accountability? How do you intend to validate if your approach is feasible?

Make Infinite Lab’s Capability to Deliver

• Proven track record: Space and Time has already deployed similar tamperproof data aggregators for other major blockchains such as BTC, Eth, Base, Sui, Polkadot, Sei, Avalanche, Arbitrum etc… used by large US financial institutions and 10k+ active devs each month.
• Unique ability for tamperproofing data: Our decentralized data warehouse and Proof of SQL protocol from Space and Time (part of the indexing effort, built in) are production-ready and purpose-built for secure blockchain data analytics.
• Experienced team – We are a team of ~30 seasoned database, blockchain, and distributed systems engineers backed by Microsoft’s venture fund and a wealth of crypto-native funds since 2022.

Feasibility: We will prototype the Cardano data aggregator by adapting our existing indexing framework to Cardano’s unique data model.

• We will adapt our existing indexing framework to Cardano’s extended UTxO (EUTxO) model, which differs significantly from account-based chains like Ethereum. Cardano transactions reference multiple inputs and outputs, each containing custom datum and script data. This structure requires specialized parsing logic to accurately index assets, scripts, and onchain state transitions.
• Indexing will also include multi-asset support, as Cardano natively supports user-defined tokens at the ledger level without smart contracts… meaning the data aggregator must track policy IDs, asset names, and quantities alongside ADA transactions.
• Our schema will account for Plutus script interactions and datum decoding so that developers can query both raw transaction data and higher-level contract states.
• We will benchmark Cardano indexing against our existing chain integrations to confirm seconds-from-chain-tip ingestion and low-latency API responses.
• Cryptographic tamperproofing will be validated end-to-end so that every query served through the API can be independently verified via Proof of SQL.
• A public API endpoint will be released early for community testing, enabling us to validate usability, coverage, and performance with real Cardano builders before full-scale deployment.

[Final Pitch] Value for Money

How does the cost of the project represent value for the Cardano ecosystem?

This is the Rolls Royce of data aggregators, suitable for institutional consumption by firms such as Fidelty, FTI Consulting, US Bank, and Chainlink, etc. Today, if a dev wants to build an app on Cardano they have to pay for mediocre 3rd-party data APIs, and do not have a data warehouse ready for SQL queries against any onchain Cardano user activity. Importantly, this funding delivers a production-ready indexing solution within 6 months and covers 36 months of maintenance, with free, verifiable data access for all Cardano developers. The long-term impact, zero-cost access model, and infrastructure-grade quality of the solution make this a high-leverage investment for the Cardano ecosystem.

The proposed budget reflects industry-standard rates for blockchain infrastructure, protocol engineering, and zero-knowledge development. Our cost estimates are based on actual indexing costs when collecting data from popular chains already available to be queried from Space and Time.
