Wallet has access to a set of private keys corresponding to stealth addresses which may own commitments on the blockchain. These private keys are needed to "recognize" incoming transactions. If the wallet is a watch-only wallet for a particular address, then it is assumed to have the private ViewKey, but only the public SpendKey.
2. Wallet can query an API node for commitments occurring between specified block heights, to obtain a set to scan for owned commitment. ([See below](#api-requirements-to-allow-detection-of-inbound-commitments) for this process.) 2. Wallet can query an API node for commitments occurring between specified block heights, to obtain sets of embedded receipts to scan for owned commitments. ([See below](#api-requirements-to-allow-detection-of-inbound-commitments) for this process.)
In what follows, we detail procedures for two different stealth address formats: one which encodes a single public key, and one which encodes two public keys. The two formats serve a similar purpose of allowing for unlinkable transactions, but the dual-key format allows for watch-only wallets, whereas the single-key format does not. The single key format is borrowed from Confidential Transactions, whereas the dual-key format is borrowed from CryptoNote-based coins such as Monero. we detail procedures for stealth address formats which encode either a single public key, or two distinct public keys in which one key is the ViewKey and the other the SpendKey. The single-key format is already in use on the BitShares network and is borrowed from the original Confidential Transactions specification. The dual-key format allows for additional wallet features and is borrowed from CryptoNote-based coins such as Monero. No changes to the network nodes are required for wallets to support dual-key address formats. In fact, the single-key format can be thought of as a special case of the dual-key format in which the same key is used as the ViewKey and the SpendKey.
