-In this chapter, we will begin where most people start when encountering the Lightning Network for the first time - choosing software. We will examine the choices of two users who represent a common use-case for the Lightning Network and learn by example. Alice, a coffee shop customer, will be using a LN wallet on her mobile device to buy coffee from Bob's Cafe. Bob, a merchant, will be using a LN node and wallet to run a point-of-sale system at his cafe so he can accept payment over the Lightning Network.

 Users have the highest degree of control by running their own Bitcoin node and LN node. However, LN nodes can also use a lightweight Bitcoin client (commonly referred to as Simplified Payment Verification (SPV)) to partially validate the correctness of their blockchain.

 Every other component of a lightning wallet brings similar considerations of trust. If all the components are under the control of the user, then the amount of trust in third parties is minimized, bringing maximum power to the user. Of course, this is a direct trade-off, as with that power comes the responsibility to manage complex software.
 
-Every user must consider their own technical skills before deciding what type of lightning wallet to use. Those with strong technical skills should use a lightning wallet that puts all of the components under the direct control of the user. Those with less technical skill but a desire to control their funds, should choose a _non-custodial_ lightning wallet, even if some of the components (other than the keystore) rely on some trusted third parties.

 Finally, those seeking simplicity and convenience, even at the expense of control and security, may choose a custodial lightning wallet. This is the least challenging option, but it _undermines the trust model of cryptocurrency_ and should, therefore, be considered only as a stepping stone towards more control and self-reliance.
