Goldsky Mirror (real-time data replication)

Problem: Accessing blockchain data is complex and time-consuming, requiring builders to run a node, write complex code, and/or set up data engineering pipelines. This process diverts valuable time from app dev.

Solution: Goldsky Mirror is a real-time data replication system that allows builders to pipe decoded blockchain data to where their app is: where to take data from, how to process it, and where to persist results.

Benefits: Compared to other approaches to indexing blockchain data, Goldsky Mirror offers a few specific and differentiated benefits:

Self-hosted: Results are persisted in a database / as flat files rather than being served only via a remote API. This allows for seamless integration with other app/user data, simplifying builders' data stack.

Self-healing: Quality checks, fixes, and improvements to data are applied automatically w/ upserts & deletes, allowing builders to focus on using the database vs. maintaining it.

Scalable: Builders can index data from multiple sources (and push to multiple sinks) with infinite horizontal scaling. This allows for complete historical backfills in record speed and seamless multi-chain apps.

Simple: Mirror pipelines can be set up through a 5-step interactive CLI, or in JSON for more flexibility. This ease of use makes building with Mirror incredibly easy yet scalable from hackathons to production use cases with millions of users.

indexed.xyz (open public dataset)

Problem: Web3 analytics often require a costly cloud datastore, limiting large-scale web3 data accessibility to pro users and institutions.

Solution: indexed.xyz is a public, open, and CC0-licensed blockchain dataset that allows anyone to freely download, copy, and use the data without any restrictions.

Benefits: For analytics use cases where chain-level data aggregation and transformation is useful, existing solutions can be limiting and indexed.xyz offers several differentiated benefits:

Open and unrestricted access: Unlike many cloud-based data solutions that impose limitations and charge for access, indexed.xyz is completely unrestricted - not even requiring an account. This allows developers, analysts, and app-builders to freely download, copy, and use the data with greater control and flexibility.

User-friendly data format: indexed.xyz uses the widely adopted .parquet format, which is natively compressed, queryable, and compatible with popular data tooling and platforms. This user-friendly format streamlines the data analysis process and makes it easier for developers to work with the data and increase developer velocity.

Local-first: Our local-first approach enables users to leverage their existing storage and compute resources, bypassing the need for a sustained internet connection and the costs associated with cloud-based storage and compute (eg. BigQuery compute fees). This allows users to work with data more efficiently and at a lower cost, especially for macro analysis.
