-A Bitcoin transaction represents a "real world" contract between two parties transferring value. Counterparties in a business interaction traditionally keep track of a payment with bills (invoices) and receipts. Delivery of a good is made by the payee once the payor has signed the receipt, agreeing to pay for the items on the invoice. Gerhardt and Hanke [0] formulate this interaction within the confines of the Bitcoin protocol using homomorphic payment addresses and the multiparty pay-to-contract protocol.

Gerhardt and Hanke [0] formulate this interaction within the confines of the Bitcoin protocol using homomorphic payment addresses and the multiparty pay-to-contract protocol.
 
 The protocol is constructed in such a way that all parties have cryptographic proof of both who is being paid and for what. Using the technique described in this BIP, an address can be provably derived from the terms of a contract and the payee's public key. This derivation scheme does not bloat the UTXO and is completely hidden to network participants; the derived address looks like any other P2(W)PKH or P2(W)SH address. Redemption of the funds requires knowledge of the contract and the payee's private key.

 This key derivation scheme requires two parties: a payer (customer) and a payee (merchant).
 The customer submits to the merchant a purchase request, specifying what goods/services they would like to buy. From the purchase request the merchant constructs an invoice (contract), specifying the billable items and total amount to be paid.
-The merchant must give this contract alongside a “payment base” extended public key to the customer. Given this information, the customer will be able to fulfill the contract by generating the public key of the payment address associated with the contract and the payment base and sending the funds there.
