The Graph in 60 seconds, quick explanation that actually covers what matters
Raw blockchain data exists but it is not queryable in any practical sense without an indexing layer. The Graph builds that layer as a decentralized network so developers do not have to maintain their own indexing infrastructure.
The practical implication: every time you interact with a dApp that displays historical data or complex on-chain state, there is a high probability a subgraph is powering it.
As more chains launch and more protocols build on top of them, the demand for reliable subgraph infrastructure either grows with the ecosystem or creates an opening for a competitor to take the market. Which do you think is more likely?
