Before an asset is deposited into a Sacred Box, a unique Sacred Claim (secure note) in the form of a string of words and letters is generated. This claim is locally generated and only the depositor will have access to this Sacred Claim.
The Claim is critical to withdraw the deposited assets and needs to be stored somewhere safe! When withdrawing the funds, the Sacred Claim cryptographically verifies that you deposited the assets before privately releasing the asset to the directed address. It also verifies that the claim exists and hasn't been redeemed, eliminating double-spend.
