The Lightning Network is changing how Bitcoin miners earn. Here's the core takeaway:
- Miners face reduced on-chain transaction fees as smaller payments move off-chain to the Lightning Network. This impacts their steady income stream.
- Block rewards are shrinking (now 3.125 BTC per block since April 2024), making transaction fees increasingly important for miners.
- Lightning Network offers new revenue opportunities, like fees from opening and closing channels, but these are less frequent than traditional on-chain transactions.
- On-chain activity is shifting toward larger, high-value transactions, such as institutional settlements, which can generate higher fees.
Miners must adapt to these changes by cutting costs, using efficient equipment, and exploring new revenue streams like running Lightning nodes or supporting Lightning infrastructure. The shift creates challenges but also new ways for miners to sustain profitability as Bitcoin evolves.
Is The Lightning Network Doomed?
How Lightning Network Changes Bitcoin Transactions
The Lightning Network reshapes Bitcoin transactions by moving many smaller payments off the main blockchain, which has a direct impact on how miners earn revenue. This shift is redefining the traditional revenue models miners have relied on.
Off-Chain Transaction Growth
The Lightning Network operates as a parallel payment system, handling transactions outside the main Bitcoin blockchain. This approach is particularly beneficial for microtransactions and frequent payments, which previously faced high on-chain fees.
Take Twitter, for example. The platform has integrated Lightning Network functionality, allowing its 360 million monthly active users to send and receive Bitcoin tips instantly through apps like Strike. Similarly, El Salvador’s government-backed Chivo wallet leverages Lightning technology to enable smooth cross-border payments, potentially saving Salvadorans around $400 million annually in money transfer fees.
The mining industry is also adapting to this shift. In March 2025, Braiins, the longest-running Bitcoin mining pool, announced it was processing over 1,000 Lightning Network payouts daily. Since rolling out Lightning payouts in February 2024, Braiins has seen consistent growth, with monthly transaction counts rising nearly 20% on average from mid-2024 into early 2025.
This rise in off-chain transactions reduces demand for on-chain transactions, reshaping how miners generate income.
Reduced Demand for On-Chain Transactions
With smaller payments moving to the Lightning Network, competition for Bitcoin block space has decreased. This trend is particularly noticeable in transactions under $1,000, which accounted for over 27% of total Bitcoin mining fees between January 2014 and November 2023.
Lightning transactions come with minimal fees, often as low as 1 satoshi (0.00000001 BTC). While this makes Lightning ideal for small payments that would otherwise be too costly on-chain, it also means miners lose out on the fees these transactions would have generated.
One study covering January 2017 to September 2019 found that if the Lightning Network had been widely adopted during Bitcoin's 2017 congestion crisis, blockchain congestion could have been reduced by 84%. While this would have improved the user experience, it also highlights the potential fee revenue miners might miss as Lightning adoption grows.
Interestingly, as smaller transactions move off-chain, the average value of on-chain Bitcoin transactions has increased. In one example, the average transaction value jumped from $4,000 to $18,000 within a year. This shift underscores the need for miners to explore alternative revenue streams, such as Lightning channel fees.
Lightning Channel Setup and Closure Fees
Although regular transaction fees are declining, the Lightning Network provides miners with new opportunities through channel management activities. Specifically, miners earn revenue from the on-chain transactions required to open and close Lightning channels.
Each Lightning channel involves two key on-chain transactions: one to open the channel and another to close it. These operations create a different revenue model for miners. Instead of collecting fees from individual transactions, miners benefit from the larger fees tied to setting up and managing these channels.
For instance, Braiins processed 13.78 BTC in Lightning withdrawals in less than a year. While miners didn’t earn fees from the individual Lightning transactions, they profited from the on-chain transactions needed to manage the channels enabling those payouts.
This model results in fewer but more substantial fee events. Large-scale Lightning implementations, such as those by major exchanges or payment processors, often require significant on-chain activity to establish and maintain their Lightning infrastructure. These operations generate meaningful fee revenue for miners, even though the subsequent Lightning payments don’t directly contribute to their earnings.
Effects on Miner Profits: Problems and Benefits
The Lightning Network is shaking things up for miners, cutting into routine fee income while introducing a new stream of high-value settlement transactions. For miners, understanding these shifts is key to adapting in this changing environment.
Lower Fees and Reduced Revenue
As the Lightning Network gains traction, it’s reducing the steady flow of on-chain fee income. The microtransactions and everyday payments that previously provided miners with a reliable revenue stream are now being handled off-chain, leading to fewer fee spikes. This shift is particularly challenging for miners who rely on consistent fees to offset costs, especially those with high electricity expenses. Without that steady income, profits become more exposed to network fluctuations, creating a much less predictable fee market.
However, while one door closes, another one opens. Miners are starting to see the upside of high-value settlement transactions.
Revenue from Settlement Transactions
Although routine fees are declining, the Lightning Network is generating opportunities for miners through larger, fee-rich settlement transactions. When major players, like exchanges or payment processors, set up Lightning infrastructure, they often batch multiple channel openings and closures into a single transaction. These operations result in higher fees compared to the smaller, everyday transactions they replace. For instance, a single institutional setup can generate fees that far outweigh those from numerous individual transactions.
Mining pools are adjusting their strategies to prioritize these high-fee settlement transactions, reshaping how blocks are constructed.
Lightning Network Pros and Cons for Miners
The Lightning Network’s impact on miner profitability is a mixed bag, with both benefits and challenges:
| Advantages | Disadvantages |
|---|---|
| High-value settlement transactions with larger fees | Significant drop in routine fee income |
| Less network congestion, improving block propagation | Greater fee market volatility and unpredictability |
| Increased demand from institutions adopting Lightning infrastructure | Shrinking margins for miners with high electricity costs |
| More predictable revenue from large infrastructure-related fees | Loss of steady income from frequent small transactions |
| Improved Bitcoin scalability, attracting more users | Possible long-term decline in overall fee revenue |
While the Lightning Network boosts Bitcoin’s scalability and long-term growth potential, it also cuts into the fee revenue that many miners depend on. Those with efficient, low-cost operations are better positioned to weather this transition, while miners operating on thin margins may face tough decisions, including upgrading equipment or revising their strategies to stay competitive.
Timing is everything. Miners who can ride out this transitional period and adapt to the new revenue landscape may find themselves in a stronger position as the Lightning Network matures and more opportunities emerge. The next section will dive deeper into how miners can navigate these changes.

Future Impact: Lightning Network's Long-Term Effects on Mining
The rise of the Lightning Network is set to transform Bitcoin mining in ways that go beyond the immediate impact on transaction fees. While the short-term changes are already evident, the long-term effects on miners and Bitcoin's security model deserve a closer look.
Fee Market Changes and Security Impact
Bitcoin's security relies on miners earning enough to sustain the network's hash rate. With block rewards halving every four years, transaction fees are becoming a crucial part of miner revenue. The Lightning Network introduces a new dynamic: fewer day-to-day transactions occur on-chain, but settlement transactions tied to channel operations still generate fees.
This shift is likely to create a new balance in the fee market. On-chain activity may center around high-value transactions, institutional settlements, and Lightning channel-related operations, all of which are willing to pay higher fees for security. At the same time, everyday payments move off-chain, reducing fee competition for smaller transactions. This effectively creates a two-tier system, where Bitcoin’s base layer serves as a settlement network for larger-scale transactions.
As block rewards continue to shrink, Bitcoin’s security model could face challenges if fee revenue from settlement transactions doesn’t grow enough to offset the decline. To stay profitable, miners may need to double down on cost-cutting measures and renewable energy solutions. Even if the network’s hash rate stabilizes at a lower level, security could remain intact if the remaining miners operate more efficiently.
This evolving fee structure is pushing miners to explore new ways to sustain their businesses.
New Opportunities for Miners
Some miners are already adapting by running Lightning nodes to earn routing fees. Others are pivoting toward supporting infrastructure that helps the Lightning Network expand.
The shift to settlement-focused mining opens doors for miners who can operate at ultra-low costs, allowing them to stay profitable even as transaction fee revenue becomes less predictable.
Additionally, institutional adoption of the Lightning Network is creating fresh demand. Companies and financial institutions building out Lightning infrastructure generate steady settlement transactions, often involving larger sums and higher fees than typical retail payments. This provides miners with a more dependable revenue stream tied to institutional activity.
Key Takeaways
The Lightning Network is reshaping Bitcoin mining, presenting both challenges and opportunities. While routine transaction fees may decline, settlement activity and high-value transfers will continue to provide a crucial source of fee revenue. This shift supports Bitcoin’s long-term potential by enabling broader adoption.
Miners who focus on cost efficiency and embrace renewable energy will be better positioned to navigate these changes. As the industry evolves, mining operations that prioritize sustainability and adaptability are likely to emerge as leaders in a maturing Bitcoin ecosystem.
