- Application Document: Silent Data Polkadot Integration
- Milestone Number: 1
Context
Silent Data is a platform for proving properties of private off-chain data in blockchain smart contract applications. This milestone extends Silent Data to support Substrate based blockchains, with Polkadot being the main focus. The Silent Data web application now includes an integration with the polkadot{.js} wallet. Support for Sr25519 and Secp256k1 signatures has been added to allow signature verification in either ink! smart contracts or Substrate pallets.
In order to improve the developer experience a Node.js library for interacting with the Silent Data API has been developed. We have also created both an example ink! smart contract and Substrate pallet to demonstrate how Silent Data can be used to securely provide off-chain data to blockchain applications.
