Private Key Derivation

After a stealth transaction is identified, the recipient must derive the private key needed to access the funds.

Steps

1. Compute Shared Secret

   • Use your viewing private key v and the ephemeral public key E to compute P' = v × E.

   • Hash P' to obtain h'.

2. Derive the Stealth Private Key

   • Let s be your spending private key.

   • Compute the stealth private key: s_stealth = s + h'.
