       <h3>Bitcoin Payment</h3>
+The following scenario outlines an ideal payment experience using Bitcoin, or a
+Bitcoin-like, cryptocurrency. In this scenario, Lenne is buying a pair of
+alpaca socks from an online retailer using a buy one get another free coupon.
+The socks are shipped to her home address.
+      </p>
+      <h4>Negotiation of Purchase Terms</h4>
+      <p>
+<strong>Discovery of Offer</strong>: Lenne searches for "warm socks,
+locally sourced" in her favorite search engine. A pair of Alpaca socks come up
+as the first hit as the Alpaca's are nearby where she lives and the online
+store provides local delivery. She has a coupon in her wallet for the store
+that she picked up several months ago and forgot she had.
+      </p>
+      <p>
+<strong>Agreement on Terms</strong>: Lenne goes to AlpacaToesCo and puts the
+socks in her online shopping cart and is shown the price. Lenne provides her
+shipping address to AlpacaToes.
+      </p>
+      <p>
+<strong>Application of Marketing Elements</strong>: When Lenne puts the socks
+in her online shopping cart, she's reminded of the "Buy one, get one" coupon
+she has in her wallet. She adds another pair of socks and continues with the
+checkout process.
+      </p>
+      <h4>Negotiation of Payment Instruments</h4>
+      <p>
+<strong>Discovery of Accepted Schemes</strong>: The website takes VISA,
+Ripple, and Bitcoin for payment.
+      </p>
+      <p>
+<strong>Selection of Payment Instruments</strong>: Lenne has a VISA card
+as well as a local Ripple wallet and a cloud-based Bitcoin wallet. Lenne
+selects her cloud-based Bitcoin wallet.
+      </p>
+      <p>
+<strong>Authentication to Access Instruments</strong>: Since the value of the
+payment is less than $50, Lenne isn't asked for her two-factor authentication
+device to approve the purchase.
+      </p>
+      <h4>Payment Processing</h4>
+      <p>
+<strong>Initiation of Processing</strong>: Lenne's cloud-based Bitcoin wallet
+provider initiates the transaction.
+        </p>
+	      <p>
+<strong>Verification of Available Funds</strong>: <em>Not applicable to
+this particular use case.</em>
+        </p>
+	      <p>
+<strong>Authorization of Transfer</strong>: AlpacaToesCo is sent a message
+from the Bitcoin cloud wallet notifying them that the transfer has been
+        </p>
+	      <p>
+<strong>Completion of Transfer</strong>: AlpacaToesCo gets a message from the
+Bitcoin cloud wallet that the transfer is complete. A Bitcoin transaction ID
+is included in the message so that AlpacaToesCo can release the product when
+the appropriate number of verifications are made on the transaction.
+        </p>
+      <h4>Delivery of Product/Receipt</h4>
+      <p>
+<strong>Delivery of Receipt</strong>: AlpacaToesCo sees 6 verifications on the
+transaction in the Bitcoin blockchain and sends a receipt of sale to Lenne's
+cloud wallet.
+      </p>
+      <p>
+<strong>Delivery of Product</strong>: AlpacaToesCo ships the package of socks
+to Lenne.
