Indexing Data
Real-Time Data
Maestro’s blockchain indexer is specifically optimized for UTXO** ledger primitives** and focuses on delivering both real-time data liveness and data accuracy. Blockchains operate as an event-driven system with probabilistic transaction finality, meaning the ledger’s “ground truth” isn’t instantly finalized—it can take some time to reach global consensus. Accessing “real-time” onchain data requires rigorous data integrity checks. Traditional solutions, like adding a block buffer to indexers, only mitigate rollbacks by providing outdated data. Maestro has designed a system that handles rollbacks gracefully and in real-time, giving users live data without sacrificing data integrity. Let’s take a closer look at the components that make up the indexer:- Indexer - Specialized pipelines that extract, match, and process on-chain information, including handling rollbacks.
- Storage - A data lake optimized for storing various types of data.
- Access - A REST API providing flexible and performant querying capabilities.
Common Use Cases
Accurate and live on-chain data is critical for delivering an optimal user experience in blockchain applications. Some common use cases for blockchain indexers include:- Smart contract-based dApps – Time-sensitive DeFi apps like DEXs, NFT marketplaces, lending protocols, games, and metaverses.
- Wallets and Decentralized IDs (DIDs) – Real-time UTxO states are crucial for Cardano wallets, cross-chain wallets, and DID systems.
- Blockchain explorers – Analytics platform require reliable access to large sets of on-chain data.
- Bridges & Web2 integrations – Blockchain bridges and integrations with traditional Web2 software require access to on-chain information.
