Umbrella Network Block Explorer Basics #4: Using Layer-2 Data in Smart Contracts
Channel: Umbrella Network
Date: 2021-07-05

To store the Layer-2 data in the Merkle Trees, users need to validate the Merkle Proof for any given transaction. This video is intended to provide a brief understanding of how Merkle Proof is validated via Umbrella Networ's SDK and Block Explorer. 

The Layer-2 Data offered by Umbrella Network is stored in the form of Merkle Trees, and to use this data via smart contracts, you need to validate a Merkle Proof. 

To generate the Merkle Proof of the data that you need to query, you will need to find the leaf node that represents the specific data point. You can then use Umbrella Network's Block Explorer to produce the required Merkle Proof, allowing your smart contract to validate the Layer-2 data points.
