+ Developers can leverage the Laconic SDK to develop Watchers, which + are the components of the Laconic Network that makes DApp + development fast and frictionless. Watchers are custom caches of + IPLD blocks. By providing proofs with our IPLD versions of Ethereum + data, a DApp can be fully verifiable with hundreds of megabytes + instead of the tens of terabytes an archive node requires, + dramatically increasing speed and efficiency, and lowering costs. +
++ With the services of a Watcher, a DApp developer can exactly define + and customize the API they need. The Watcher runs queries that are + efficient and relevant to the DApp. Another key benefit of Watchers + is that they are composable, enabling a developer to reference data + previously derived from the Ethereum blockchain by means of another + Watcher, within their Watcher. +
+A Watcher serves three fundamental purposes:
+
+ It queries precisely the data a DApp needs.
++ It transforms the queried data to make it consumable to the + DApp. +
+It caches the data for fast and inexpensive access.
