Summary of Andreas M. Antonopoulos, Olaoluwa Osuntokun & René Pickhardt's Mastering the Lightning Network

#1 The Lightning Network is a network of payment channels that allows users to make instant, off-chain payments. It is a layer above the Bitcoin blockchain that allows people to transact quickly and securely.

#2 A payment channel is a financial relationship between two nodes, called the channel partners, that allocates a balance of funds between the two channel partners. The cryptographic protocol ensures that one channel partner cannot cheat the other.

#3 The payment channel is based on a 2-of-2 multisignature address on the Bitcoin blockchain, for which you hold one key and your channel partner holds the other key. You and your channel partner negotiate a sequence of transactions that spend from this multisignature address.

#4 The Lightning Network is a comprehensive communication protocol that allows peers to exchange Lightning messages to achieve the transfer of bitcoin. The communication protocol defines how Lightning messages are encrypted and exchanged.

#1

The Lightning Network is a network of payment channels that allows users to make instant, off-chain payments. It is a layer above the Bitcoin blockchain that allows people to transact quickly and securely.

#2

A payment channel is a financial relationship between two nodes, called the channel partners, that allocates a balance of funds between the two channel partners. The cryptographic protocol ensures that one channel partner cannot cheat the other.

#3

The payment channel is based on a 2-of-2 multisignature address on the Bitcoin blockchain, for which you hold one key and your channel partner holds the other key. You and your channel partner negotiate a sequence of transactions that spend from this multisignature address.

#4

The Lightning Network is a comprehensive communication protocol that allows peers to exchange Lightning messages to achieve the transfer of bitcoin. The communication protocol defines how Lightning messages are encrypted and exchanged.

#5

Payment channels have several interesting and useful properties: they are extremely fast, they do not require the confirmation of Bitcoin blocks, and they are private. They are only limited by the capacity of the channel and the size of a Bitcoin transaction, which is limited to around 20000 bytes.

#6

The Lightning Network uses a 2-of-2 multisignature scheme to build a payment channel.

#7

The fundamental building block of a payment channel is a 2-of-2 multisignature address. The two channel partners fund the payment channel by sending bitcoin to the multisignature address. This transaction is called the funding transaction, and is recorded on the Bitcoin blockchain.

#8

2-of-2 multisignature addresses seem to carry some risk. What if your channel partner refuses to sign a transaction to release the funds. Are they stuck forever. The Lightning Network protocol solves this by creating a refund transaction that can be signed by either Alice or Bob.

#9

A commitment transaction is a transaction that pays each channel partner their channel balance and ensures that the channel partners do not have to trust each other. By signing a commitment transaction, each channel partner commits to the current balance and gives the other channel partner the ability to get their funds back whenever they want.

#10

The Lightning Network is a protocol that allows people to make payments through a series of transactions
