 address::
     A Bitcoin address looks like +1DSrfJdB2AnWaFNgSbv3MZC2m74996JafV+. It consists of a string of letters and numbers. It's really an encoded base58check version of a public key 160-bit hash. Just as you ask others to send an email to your email address, you would ask others to send you bitcoin to one of your Bitcoin addresses.
 
+AMP::
+   Atomic Multipath Payments.
+   A method for payments where the sender can use more than one of their channels to forward a payment.
+   By default, a sender uses one channel to forward payment. 
+   This can cause issues, for example, where a sender has an two channels with an outgoing capacity of 0.5 BTC but wishes to forward a payment of 0.8 BTC.
+   By default, this payment would fail without rebalancing. 
+   With AMP, the sender can split the payment between these channels and either have the entire payment succeed or fail, with no partial payment possible.

 Asymmetric Cryptographic System::
     Asymmetric cryptography, or public-key cryptography, is a cryptographic system that uses pairs of keys: public keys which may be disseminated widely, and private keys which are known only to the owner.
     The generation of such keys depends on cryptographic algorithms based on mathematical problems to produce one-way functions.
