閃電網路：比特幣可擴展性挑戰的解決方案

The thrilling fact about the decentralised economy is that technology always evolves and develops in response to ongoing issues. Ultimately, these tools were innovated to better serve users and provide better facilitation than centralised methods.

關於去中心化經濟的令人興奮的事實是，科技總是為了應對持續存在的問題而不斷發展和發展。最終，這些工具進行了創新，以更好地服務使用者並提供比集中式方法更好的便利性。

The Bitcoin blockchain was the first network developed to register and track crypto transactions using BTC and other tokens minted on the same network. However, due to the increasing demand and congestion on the blockchain, the lighting network was introduced to solve this problem.

比特幣區塊鏈是第一個開發的網絡，用於使用 BTC 和同一網路上鑄造的其他代幣來註冊和追蹤加密交易。然而，由於區塊鏈的需求不斷增加和擁堵，閃電網路被引入來解決這個問題。

Let’s discuss exactly what the Bitcoin lightning network is and how it solves the blockchain performance problem.

我們來具體討論一下比特幣閃電網路是什麼以及它如何解決區塊鏈效能問題。

What is Lightning Network in BTC Blockchain?

The Bitcoin lightning network is a layer-2 scaling solution developed on the BTC mainnet to offload the network congestion. The Bitcoin network has become highly demanded, and its fees have increased over time due to coin capitalisation and its role as the first and best cryptocurrency.

BTC區塊鏈中的閃電網路是什麼？比特幣閃電網路是在BTC主網路上開發的第二層擴容解決方案，用於緩解網路擁塞。比特幣網路的需求量很大，由於硬幣資本化及其作為第一個也是最好的加密貨幣的作用，其費用隨著時間的推移而增加。

This innovation was developed to fix the speed and scalability issues of the blockchain network by processing payments, operating digital assets and executing transactions on the LN instead of the mainnet. The BTC main network can be used to register new blocks and add/release newly minted Bitcoins to miners.

這項創新旨在透過在閃電網路（而不是主網上）上處理支付、操作數位資產和執行交易來解決區塊鏈網路的速度和可擴展性問題。 BTC主網路可用於註冊新區塊並向礦工添加/釋放新鑄造的比特幣。

This protocol helps avoid congestion time and increased gas fees that occur during network peak times, where transactions take a long time to be processed, and transaction fees can exceed $50 per payment.

該協議有助於避免網路高峰時段出現的擁塞時間和 Gas 費用增加，此時交易需要很長時間才能處理，並且每次付款的交易費用可能超過 50 美元。

How Does Bitcoin LN Work?

The lightning network happens directly between users with minimum interference from the blockchain’s main operators. This peer-to-peer transaction contributes to faster payment settlements and decreased fees.

比特幣閃電網路是如何運作的？閃電網路直接發生在用戶之間，受到區塊鏈主要營運商的干擾最小。這種點對點交易有助於加快支付結算速度並降低費用。

Operations processed on the layer-2 network minimise the workload from miners, which reduces its security exposure. Transactions processed using LN technology are settled faster, which minimises the risk of being targeted by hackers while being processed or in the pending pool.

在第二層網路上處理的操作最大限度地減少了礦工的工作量，從而降低了安全風險。使用閃電網路技術處理的交易可以更快地結算，從而最大限度地降低在處理過程中或在待處理池中被駭客攻擊的風險。

Despite being developed mainly for the Bitcoin blockchain, other chains and networks started using a similar technology to improve the network performance and increase their DeFi ecosystems.

儘管主要是為比特幣區塊鏈開發的，但其他鏈和網路也開始使用類似的技術來提高網路效能並擴大其 DeFi 生態系統。

Features of Bitcoin Lightning Network

The Bitcoin lightning network solution is one of the many layer-2 additions many protocols are developing, such as Ethereum, Avalanche and Polygon, which proves the utility of this technology. Let’s take a look at some of the benefits of this network solution.

比特幣閃電網路的特點比特幣閃電網路解決方案是許多協議正在開發的眾多第 2 層附加功能之一，例如以太坊、Avalanche 和 Polygon，這證明了該技術的實用性。讓我們來看看這個網路解決方案的一些優勢。

Elevated Security

This technology uses the Basis of Lightning Technology 12 (BOLT 12), which is a safer protocol for data encryption before reaching consensus. This way, transaction information is not exposed to nodes, which makes the process safer.

更高的安全性該技術使用閃電技術基礎 12 (BOLT 1​​2)，這是在達成共識之前進行資料加密的更安全的協議。這樣，交易資訊就不會暴露給節點，使流程更加安全。

Additionally, LN transactions are settled almost instantly, which minimises the risk of being hacked or redirected to other destinations.

此外，閃電網路交易幾乎可以立即結算，從而最大限度地降低了被駭客攻擊或重定向到其他目的地的風險。

High Scalability

Due to the fact that the Bitcoin chain is the first and oldest blockchain, some consider it a rigid platform that does not accommodate modern flexibility and scalability.

高可擴展性由於比特幣鏈是第一個也是最古老的區塊鏈，有些人認為它是一個僵化的平台，無法適應現代的靈活性和可擴展性。

Therefore, the lightning network solves this issue by adding layer 2, which facilitates fractional payments, hosting decentralised applications and interaction with other blockchains and protocols.

因此，閃電網路透過添加第 2 層解決了這個問題，該第 2 層促進了部分支付、託管去中心化應用程式以及與其他區塊鏈和協議的交互。

Quick Settlements

Instead of the traditional transaction process of going to the pending list and waiting for miners to process payments, the LN network finalises payments through multiple channels and network participants to find the fastest way possible to settle each order.

快速結算 閃電網路不再採用傳統的進入待處理清單並等待礦工處理付款的交易流程，而是透過多個管道和網路參與者來完成付款，以找到盡可能最快的方式來結算每個訂單。

This solution minimises the work on the mainnet, which can be congested with long waiting pending times and increased fees.

此解決方案最大限度地減少了主網上的工作量，主網上可能因等待時間過長和費用增加而變得擁擠。

Less Energy Consumption

Bitcoin transactions are known for being high energy-requiring, consuming a lot of energy from processors and mining machines. This increased demand can have catastrophic environmental consequences. 

能源消耗更少眾所周知，比特幣交易需要大量能源，會消耗處理器和礦機的大量能源。這種需求的增加可能會帶來災難性的環境後果。

Therefore, a layer-2 solution offloads some of the transaction processing burden from the main network with minimum machine requirements classically used by proof-of-work protocols. 

因此，第 2 層解決方案以工作量證明協定經典使用的最低機器要求來減輕主網路的一些事務處理負擔。

Conclusion

The Bitcoin lightning network is a new invention that elevates the BTC blockchain utility and solves its main challenges. It is a layer-2 solution that offloads some transactions from the mainnet to process and settle them directly with minimum power consumption and low fees.

結論比特幣閃電網路是一項新發明，它提升了 BTC 區塊鏈的實用性並解決了其主要挑戰​​。它是一種第二層解決方案，可以將一些交易從主網卸載，直接以最小的功耗和較低的費用進行處理和結算。

This activity results in faster processing times and lower exposure risks. Additionally, the LN protocol increases network interoperability, allowing it to transact and interact with other chains and manage dApps.
