This data can be transformed, organized, and shared across applications for anyone to query with just a few keystrokes. Before The Graph, teams had to develop and operate proprietary indexing servers. This required significant engineering and hardware resources and broke the important security properties required for decentralization. All data is stored and processed on open networks with verifiable integrity. The Graph makes querying this data fast, reliable, and secure.
How I built an Interactive 30-Day Bitcoin Price Graph with React and an API
Entrepeneurs are creating next level apps to scale human coordination on the internet. It's a new frontier and we're just getting started. By combining Web3 protocols, developers can build dApps with powerful new features for solving the world's greatest challenges. A marketplace of service providers ensures that data remains open and that dApps continue to run no matter what.
Individuals who organize data and signal which subgraphs are useful and accurate. Individuals who delegate stake to Indexers to contribute to securing the network without running a Graph Node themselves. Uniswap enables anyone to create markets and bootstrap liquidity. Easily track markets, volume and orders. Decentraland Marketplace lets users find land, accessories and collectibles for an expansive digital world. Aragon empowers individuals to create internet native organizations and resolve community disputes with Aragon Court.
Futureswap uses graphprotocol for its frontend. It helped us make our system more robust and reliable. Thanks for everything you are doing!

We then bind the onMessage function to the onmessage event listener. This is where we handle each of the transactions sent via the WebSocket. The data also contains a Bitcoin transaction hash, which is the unique ID for every verified transaction in the blockchain. In our Bitcoin timeline, the entities similar to nodes in KeyLines down the left-hand side represent addresses.
KronoGraph has helpfully aggregated these to fit as much data on the screen as possible.

The events similar to links on each timeline showing individual transactions. Entities shown as a brighter pink color represent addresses with more funds coming in than going out. We just need to create an array of nodes and links. KronoGraph expects a slightly different data format to account for cases where events can be connected, or can refer to more than two nodes.

The equivalent function call for KronoGraph is the set function, shown here in the entire mergeWithChart function:. We want smooth animations across the dashboard as the data changes. This makes sure we only animate new data once the previous animation has completed. Investigators and analysts will want to pause live updates if they receive an alert or spot an anomaly in real time that needs further investigation.
I think they look great! One neat trick: I automatically pause the updates when a user zooms into the Bitcoin timelines past a certain threshold.
