Lightning Network Payment Technology Advantages – Bitcoin Magazine
This is an belief editorial by Yuya Ogawa, a application engineer and co-host of the Diamond Arms group.
This write-up is primarily based on the content material of the “Understanding Lightning” report made by the Diamond Hands community, the greatest Lightning Network community in Japan. The report aims to present an overview of Lightning’s know-how and ecosystem for a non-technical viewers.
What is So Special About The Lightning Community?
Bitcoin was brought into this earth over a decade in the past to enable peer-to-peer payments devoid of the have to have for a trustworthy third celebration. In order to keep this censorship resistance, Bitcoin limits its throughput to 1M vBytes for every block, each and every 10 minutes, trying to keep it uncomplicated for any individual to run their personal node.
The Lightning Community is Layer 2 engineering crafted atop the Bitcoin blockchain, enabling speedier and cheaper payments, massively improved scalability and superior privacy without the need of compromises to censorship resistance and decentralization. In this article, we relegate the technological particulars for a further working day, as an alternative focusing on Lightning’s censorship resistance and scalability properties.
Bitcoin scales by creating layers on major of the base chain
Decentralized And Censorship Resistant
Just like Bitcoin, Lightning end users can run their own nodes and regulate their have payment channels. This is in stark distinction to the vast bulk of emerging Layer 2 systems in the broader crypto ecosystem.
For example, rollups on Ethereum exist on-chain as a solitary on-chain wise contract that stores the point out of all of its users — as opposed to countless numbers of unique payment channels in Lightning’s case. For Ethereum, an operator node is in charge of managing and updating this point out, thus introducing a vector for censorship or exploitation. Even if Ethereum and Solana had been sufficiently decentralized and censorship-resistant networks, Layer 2 buyers can be influenced if the sensible deal or operator node is censored or exploited.
In Lightning, every consumer produces payment channels to produce a substantial world wide web for payments. So, even if a consumer is censored or exploited, the relaxation of the community continues to be practical. Despite the fact that there is valid problem with regards to the emergence of important hubs (well-liked nodes that bring in quite a few payment channels) and their vulnerability to censorship, even in such a case, people are free to create different payment channels to circumvent these nodes, if desired. This censorship-resistant dynamic, enabled by Lightning’s decentralization, is unparalleled by most other Layer 2 technologies.
Massively Scalable
Payments on Lightning usually traverse many payment channels to achieve their vacation spot. Typically, we see payments that are routed around no a lot more than 4 or five hops (routing nodes). Assuming each and every hop can take one particular second, the payment is completed in 4 to five seconds. If the payment necessitates zero hops, i.e., if you share a payment channel with the desired destination, it will very likely settle in a fraction of a second.
Fees are ordinarily about .1% of the payment sum, so a $1 payment is probable to value .1 cents in service fees. For zero-hop payments, there is no cost. The throughput of every node is confined, with Lightning Network Daemon (LND) benchmark success suggesting that a node can approach 50 transactions for every next (tps) out-of-the-box (see information listed here). Having said that, as stated in the report, computer software optimizations should be equipped to provide this determine to 1,000 tps. Additionally, given that the network can procedure payments in parallel, if 1,000 pairs of nodes throughout the network all perform at 1,000 tps, the network as a entire does 1,000,000 tps.

Routing Nodes, At Your Support!
Just as miners are incentivized by transaction charges and recently minted cash in proof-of-work mining, the nodes that forward payments across Lightning are incentivized by routing charges. A aggressive current market for hashing presents stability to the Bitcoin blockchain a aggressive marketplace for payment routing final results in less costly and more reputable payments on Lightning.
Because routing nodes earn a payment each individual time they ahead a payment, they the natural way goal to route as substantially benefit as possible. Having said that, mispricing liquidity can guide to unbalanced channel ability and routing failures — which reward no one particular, including the routing nodes associated. In purchase to optimize their earnings, routing nodes attempt to harmony their channels, bettering payment success prices and settlement occasions throughout the community. Extra routing nodes also implies more attainable routes which can be employed as solutions, improving upon community trustworthiness.
Routing nodes maintain Lightning decentralized and censorship resistant.
Summary
The Lightning Network is very decentralized and censorship resistant many thanks to its reliance on the Bitcoin blockchain the place people can freely produce new payment channels. Moreover, likewise to how a aggressive market place for mining outcomes in safety on Layer 1, routing nodes compete with each individual other to deliver secure and competitively priced payment forwarding on Lightning. Bitcoin permits trustless payments as envisioned by Satoshi Nakamoto more than 10 years ago, and the Lightning Community is an attempt to vastly enhance its scalability without the need of compromising on people foundational values.
