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.
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.

This shared secret may be directly used as a key, or to derive another key.
The key, or the derived key, can then be used to encrypt subsequent communications using a symmetric-key cipher.
An example of the derived key would be the ephemeral key used by the SPHINX Mix Format.

A digital signature is a mathematical scheme for verifying the authenticity of digital messages or documents.

Most commonly they are related to supported routing formats.
They are announced in the `_init_` message of the peer protocol as well as the `_channel_announcement_` and `_node_announcement_` messages of the gossip protocol.
Gossip Protocol::
Lightning Network nodes send and receive information about the topology of the Lightning Network through gossip messages which are exchanged with their peers.
The gossip protocol is mainly defined in BOLT 7 and defines the format of the _node_announcement_, _channel_announcement_ and _channel_update messages_.
@ -199,7 +197,6 @@ Hash Function::
It is infeasible to find two different messages with the same hash value.
A hashlock is a type of encumbrance that restricts the spending of an output until a specified piece of data is publicly revealed. Hashlocks have the useful property that once any hashlock is opened publicly, any other hashlock secured using the same key can also be opened. This makes it possible to create multiple outputs that are all encumbered by the same hashlock and which all become spendable at the same time.

Lightning Network::
The Lightning Network is a protocol on top of bitcoin (or other cryptocurrencies).
It creates a network of payment channels which enable the trustless forwarding of payments through the network with the help of HTLCs and Onion Routing.

There are currently three methods known to construct a fully duplex bidirectional payment channel.
Christian Decker proposed a method in his PhD thesis based on invalidation trees.
In the Lightning Network whitepaper, Joseph Poon and Tadge Dryja describe the Revocable Sequence Maturity Contract based method that is currently being implemented on the Lightning Network.
Recently Christian Decker et al. came up with the Eltoo mechanism which would require a Bitcoin softfork.
