Example showing how to use Irys with Lit protocol

Encrypting on-chain data

Data uploaded to Irys is stored permanently on Arweave. Once on Arweave, this data becomes publicly accessible, anyone can view or retrieve it. For projects where privacy is a concern, you can use LitProtocol to encrypt data before storing it on Irys.

This repository teaches you how to:

• Encrypt data before storing it on-chain
• Establish a set of rules determining who can decrypt the data
• Decrypt data

Technology

• Irys for uploading data
• Lit v3 for encrypting and decrypting data

Encrypting data

There are three steps to encrypting data

• Obtain a wallet signature (AuthSig), which proves you own a wallet
• Define access control conditions for who can decrypt your data
• Connect to a Lit node and request that it encrypt your data

Once encrypted, use Irys to store your data on Arweave.

Decrypting data

There are three steps to decrypting data:

• Obtain a wallet signature (AuthSig), which proves you own a wallet
• Retrieve data stored on Arweave via the Irys gateway
• Connect to a Lit node and request it decrypt your data
