Ethereum: Lightning network and lightweight clients

Lightning Network and lightweight Clients: Understanding of the relationship

The Ethereum Lightning Network, a Layer-2 scaling solution for the Ethereum Blockchain, has recently received considerable attention. One of the most important features that distinguish from other scalability solutions is the ability to deal with lightning -fast transactions without affecting security or decentralization. In this article we deal with the changeover of the flash network with light clients and examine the concept behind the opening of a payment channel.

Light clients

Light clients are special software programs that were designed on Ethereum nodes or wallets for which the complete node functions are not required. These clients want to optimize storage space and arithmetic resources and make them ideal for mobile devices, IoT applications or networks with a low bandwidth. However, light clients still need a way to interact with the blockchain in which the flash network comes into play.

The flash network

The Lightning network is a P2P protocol (peer-to-peer) that enables quick and cheap transactions between several addresses without relying on a central authority. It works by creating payment channels in which a knot acts as a “payee” and someone else as “payer”. The payer sends donations to the payee, who then stores them in a pool of coins until they are ready to be output.

Light customers and payment channels

In order to enable lightning transactions on the blockchain, light customers must interact with payment channels. This is how it works:

• Opening of a payment channel : A payer creates a new payment channel by opening a channel with another knot (the payee). This includes writing a transaction to create the channel on the blockchain.

• Coins stuck : The payer sets coins from its balance in the coins in the canal and essentially blocks average until they are ready to be output.

• Lightning Network Relay : A relay node (a light client) is added to the payment channel, which enables quick and cheap transactions between knots.

If a transaction is carried out in the network, it is forwarded by several nodes to ensure that the transaction is confirmed via all participating nodes. This process is referred to as “twinning”.

Do I understand correctly that opening a payment channel on the blockchain requires a letter before double evening?

You are absolutely right! In fact, opening a payment channel requires writing transactions on the blockchain to protect yourself from double attacks. However, this process does not include opening a separate transaction. Instead, it is integrated into the existing transaction flow.

The writing process is part of the transaction that creates the channel and places coins in the pool. This ensures that after opening the channel, all subsequent transactions in it are safe against double attacks.

Integrity

You also have quite about the importance of integrity in this process. The flash network is based on the cryptographic properties of the blockchain to ensure the validity of the transaction. By using a mixture of cryptographic techniques such as cryptography (Elliptic Curve Cryptography) and HASH functions, the network transactions protects against manipulation and repeat attacks.

In summary, the Lightning network will treat light clients by activating fast and cheap transactions via payment channels. To achieve this, opening a payment channel requires writing transactions on the blockchain to protect yourself from double attacks. The use of cryptographic techniques ensures integrity and security throughout the process.

The next time you come across a lightning -fast transaction or a payment channel on Ethereum, you remember the complicated relationship between the scalability functions of the network, the light client and the importance of integrity in the process.
