Subsquid Sponsors Gitcoin Grants Round 12 Hackathon
Hackathons play a big part in Subsquid’s history, given that a Hackusama event was where Subsquid was conceived. It is with pride then that Subsquid can announce that it is sponsoring four bounties in the Gitcoin Grants Round 12 Hackathon, which runs until December 16, and we are very excited to see what great implementations of the Subsquid protocol are conceived as a result.
One of the key challenges for developers working in the DeFi sector remains developing tools that can allow other developers to harness the power of their preferred ecosystem. This is particularly the case with a new protocol like Polkadot/Kusama. Subsquid is the most advanced framework on the market for turning on-chain data on the Polkadot/Kusama blockchain into an easy-to-use GraphQL API, opening the door for developers to retrieve a wide variety of data from the network quickly and easily.
Subsquid is able to transform on-chain data thanks to its purpose-built Hydra framework which continually scans and organizes blockchain data as it is added rather than only when requests are made. This rapidly speeds up query processing time with fewer demands being made of the protocol when multiple queries are made. The cross-blockchain nature of Subsquid combined with the speed of the Polkadot/Kusama blockchains means that applications that were previously unworkable due to the scope of the data required are now possible, which only benefits developers and end users.
Subsquid will be joined at the Hackathon by cryptocurrency luminaries such as Binance Smart Chain, Ledger, and Fluence, demonstrating the attraction that such a big event like this brings. We’re sure that with such big players backing the hackathon there will be some awesome creations coming out.
We can’t wait to see what DApp developers are going to do with Subsquid’s next generation protocol!
The Grants Round 12 Hackathon will consist of four challenges, and to help you get started here’s a little guide to let you know what’s involved for each one:
Challenge 1: Marry Ethereum with Substrate chains
Add the possibility to fetch EVM events from a contract alongside the Substrate events defined in the manifest. Since there is no canonical order you should come up with an ad-hoc synchronization algorithm to make sure that the events from a Substrate chain and Ethereum are merged in a deterministic and sound way.
Challenge 2: Aggregate data from multiple chains in a single Subsquid API
The goal is to add the possibility to fetch events from multiple data sources defined in the manifest.
Challenge 3: Index non-Substrate Chain Data
Build a GraphQL endpoint for any non-Substrate-based chain.
Challenge 4: Build a killer App with Subsquid
Get creative and leverage the power, expressiveness and customization capabilities of Subsquid and the Hydra framework. With Subsquid, you define your data in a schema file and get a ready-to-use powerful API straight away. To populate the database, define your ETL pipeline with mapping scripts and convert the source data into your target entities.
If you’re taking part in the Gitcoin Grants Round 12 Hackathon then good luck, and may the best squid win!
