Ethereum: How are paths found in Lightning Network?

Discovering payment paths on the lightning network: a step by step guide

Lightning Network (LN) is a decentralized and point -to -point network that allows fast and cheap transfronights. One of its main features is the ability to find payment paths between two knots, also known as hops. In this article, we will explore how payment paths are discovered on the Lightning network.

What are payment paths?

A Payment path in LN refers to a series of hops (or transactions) that allow quick and cheap transionic payments. Each jump is performed by multiple knots on the network, ensuring that payment is efficiently and reliable. Pathways are essential to reach fast and low cost international trade.

How do we find the payment paths?

Nodes in LN use a combination of algorithms and data structures to find payment paths. Here is a simplified view of the process:

• Node ID : Each node on the network assigns an exclusive identifier (id) to itself.

• Payment path request : When two knots want to negotiate with each other, they create a request for a payment path.

• Way Algorithm : The applicants’ nodes use their IDS and capacity available to find a valid payment path using an algorithm as the shortest problem of the path (spp). This algorithm is used by many cryptographic libraries on the network.

• Construction of the path : After a valid payment path is found, the knots constitute it by performing the jump in a specific request.

TYPES OF PAYMENT PATHS

There are two types of payment paths:

• Simple payment paths : These are direct payments between two knots.

Capacity and availability of the ln node

To find a payment path, nodes need access to certain capacity values ​​on the network. This is determined by factors such as:

• Node availability

  

  : the availability of each node in the network.

• Capacity Limits : Each node has a limited amount of capacity available for payments.

Finding Payments of Payment in Practice

To give you an idea of ​​how we find the payment paths, consider this simple example:

• Node A wants to change 10 BTC (Bitcoin) with node B.

• Both nodes have 1000 BTC and 500 BTC, respectively, which leaves them with a capacity of 400 BTC.

• The requesting node uses the shorter problem algorithm on the way to find a valid payment path between node A and node B.

Conclusion

Discovering the payment paths on the Lightning network is a complex process that involves algorithms, data structures and availability of us. Understanding how the network nodes collaborate to find valid payment paths, we can get information about the operation of the LN ecosystem. With its potential for rapid and low -cost international trade, Lightning Network has the power to transform the way people perform transionic transactions.

Code Example: Construction of the Payment Way

Here is an example of simplified code in GO that demonstrates how nodes in network construction payment paths using a spp algorithm:

`go

Main package

import (

“Crypto/X/ED25519”

“FMT”

“github.com/ethereum/go-ethereum/eth util”

)

FUNC MAIN () {

// Define node ids and capabilities

Nodeaid: = “0x … node-a-id …”

nodebid: = “0x … node-b-id …”

// Define payment goals and goals

Quantity: = 10

Targeta: = “0x … Target-a-Address …”

// Define capacity limits for each node

Capalemimite: = 1000

CapacityLimitb: = 500

// Create an instance of the spp algorithm

spp: = Util.NewSPPalgorithm ()

// Find valid payment paths between node A and node B

Way, Err: = spp.findpath (nodeaid, target, capacatelimite, capacatelimitb)

If you err! = Nil {

fmt.println (ERR)

return

}

// Print the payment path built
