Identifying Relevant Transactions for Wallets
Given that anonymous transactions are visible on the public blockchain, a wallet must determine its own transactions by analyzing specific broadcasted metadata (ePK, VT):
Derive a shared secret by performing an elliptic curve operation between the wallet’s viewing private key and the ephemeral public key ePK, leveraging ECDH as previously described.
Compute VT by applying a cryptographic hash to the derived shared secret.
Compare the computed VT with the broadcasted transaction’s VT. A match confirms the transaction pertains to the wallet.
