Description

Nakji acts as a transporter of data from the blockchain to the Internet. It efficiently moves millions of data points off-chain to be accessed freely and openly by anyone who wants to connect to Nakji’s set of APIs. Nakji's robust blockchain data infrastructure solution provides cross-chain data indexed and queried with ease, seamless access to smart contract activities across blockchains and real-time data access with millisecond refresh rates. This allows developers to create Web 3.0 apps with familiar data backend structure as they can grab blockchain data via SQL, WebSocket, GraphQL, and Rest API.

Problem statement

We’ve identified 3 major problems in the Web 3.0 data infrastructure level:

1. Limited multi-chain data coverage– not all on-chain data from major blockchains are made available (only Ethereum had decent coverage).
2. On-chain data providers have unreliable uptime and slow “real-time” data
3. It is costly and inefficient to build and maintain in-house data infrastructure

Proposed solution

To solve the above industry problems, we built Nakji Network, differentiated from existing data providers in many dimensions. Our first edge is being chain agnostic. Today, we are integrated with Ethereum, Harmony, Polygon, StarkEx, Solana, Binance Smart Chain, Avalanche, Fantom, Optimism, and Flow (coming soon), as well Quickswap, Ronin/Axie Infinity, Compound, MakerDAO, and more. Our second edge is our speed. We query up to 20 times faster than our leading competitor. Our third edge is our team. Our team brings decades of development and product management experience in and out of Web 3.0 and Web 2.0. Our co-founders built Nakji's industry grade, core data infrastructure platform all in-house, by themselves.

Impact

In what ways does this benefit the broader Flow developer ecosystem?

Nakji would like to collaborate with Flow and help grow the Flow ecosystem by indexing Flow data and making them available to as many Web 3.0 developers as possible free of charge (for the time being). We are also expanding the Nakji docs (https://docs.nakji.network/) to educate the developer community about Flow and exploring a high-level dashboard of Flow data on one of our landing pages.

Nakji will offer the Flow community with fast and easy access to real-time on-chain data, making the developer experience more frictionless than ever and catalyzing growth of the overall ecosystem.

Milestones and funding

Milestone	Deliverables	Timeline	Risks	USD proposal
1 - Integrate Flow into Nakji Network	Flow on-chain data APIs	15 man-days	May need support from Flow engineering team, especially for getting access to backfill all historical data.	$15,000
2 - Make APIs available to Flow and its ecosystem	Public and accessible Flow on-chain data APIs	10 man-days	-	$10,000
3 - Expand Nakji docs (https://docs.nakji.network/docs/intro) with Flow	Updated Nakji docs	5 man-days	-	$5,000
4 - [optional] Flow dashboard on Nakji’s landing page	Web page with Flow analytics	10 man-days	-	$10,000

Total $30,000 (excluding optional Milestone 4)

Purpose of Funds: Funds will be used for initial software development for building the connector, the APIs, and making the APIs publicly available. On-going maintenance and server costs have not been included and are optional. We are also requesting a technical point of contact from Flow’s engineering team, especially for getting access to backfill all historical data.
