Janus Indexer Core

Indexer Core is the bridge between Dapp and SmartContract. It is responsible for extracting metadata that will be indexed, interacting with the Indexer smart contract and also for communicating with the storage layer.

For smart contracts we currently support only Ethereum and for storage currently only IPFS, but we plan to include other smart contract engines and decentralized storage solutions in the future.

Featured Technologies

IPFS: The InterPlanetary File System is a protocol and peer-to-peer network for storing and sharing data in a distributed file system.

Ethereum: Is an open source, public, blockchain-based distributed computing platform and operating system featuring smart contract functionality.

TypeScript: Is an open-source programming language developed and maintained by Microsoft. It is a strict syntactical superset of JavaScript, and adds optional static typing to the language.
