North Carolina Senate Overrides Governor’s Veto to Pass Federal CBDC Ban Bill
In a Senate vote to override the veto, 12 Democrats who initially supported North Carolina's bill to ban CBDCs switched their stance.
Key Takeaways:
Merge-Mining Increases Profit Potential: Fractal Bitcoin merges with Bitcoin, enabling miners to mine cryptocurrencies using the same hardware. This boosts mining profits, especially in the post-halving environment, without requiring costly hardware upgrades.
Increased Efficiency But Lower Fees: While Fractal Bitcoin improves transaction throughput and network efficiency, it may reduce congestion and lower transaction fees. This could impact miners’ fee-based revenue, although higher transaction volume might offset some losses.
Reward Dilution Risk: Transactions processed across fractal sub-networks may require rewards to be split between the main Bitcoin chain and the fractals, potentially diluting individual miner earnings from transaction fees and block rewards.
Fractal Bitcoin is a novel concept in cryptocurrency, aiming to address scalability and transaction efficiency issues in the Bitcoin (BTC) network.
Overview
TheMinerMag announced that Fractal BTC is merge-mined with BTC, allowing miners to use the same hardware to mine both cryptocurrencies simultaneously. This setup offers BTC miners a lucrative opportunity to upgrade or repurpose their facilities for AI or high-performance computing. Designed to enhance the blockchain’s ability to handle more transactions while maintaining its core decentralisation and security, Fractal BTC could reshape how BTC operates. However, this innovation raises essential questions for mining revenues, one of the most crucial elements of the BTC ecosystem. With the potential to change transaction processing and reward structures, Fractal BTC could either boost or undermine the profitability of BTC mining operations.
How Fractal Bitcoin Works
Fractal BTC aims to improve upon BTC’s existing scalability and efficiency issues. While highly secure, the BTC blockchain faces challenges with slow transaction speeds and high fees during periods of heavy network activity. The inherent limitations in block size and the 10-minute block interval have made it difficult for BTC to process a large volume of transactions in a short period. Fractal BTC proposes a layered approach to solving these issues by creating sub-networks or “fractals” that allow more minor, more localised transaction sets to be processed separately from the leading BTC network.
These fractals operate autonomously but remain connected to the primary blockchain, helping reduce congestion on the leading network. Fractal BTC enhances throughput by processing transactions more efficiently and offloading some of the workload from the main BTC chain without compromising the network’s decentralisation or security. For miners, this development could fundamentally change how transactions are processed, and rewards are distributed. As the fractals process transactions, miners will have a role in securing and validating both fractal and main-chain transactions, potentially creating new avenues for earning rewards. However, this could also mean shifts in transaction fee structures and block rewards, both essential to mining revenue.
Impact on Mining Revenues
Introducing Fractal BTC presents a mixed bag for miners, particularly regarding its impact on revenue streams. On the positive side, Fractal BTC could reduce network congestion, making transaction processing faster and cheaper. During periods of high demand, BTC’s network is often congested, leading to increased transaction fees as customers compete to have their transactions included in the next block. Following the April 2024 halving event, the minting of BTC Runes generated 1,200 BTC in network fees for miners by the end of the month, helping to counterbalance the reduction in block rewards initially. Miners, in turn, benefit from higher fees during these times. However, with Fractal BTC easing congestion, the need for high fees may diminish, potentially reducing the total transaction fees miners collect. Moreover, Fractal BTC could improve network efficiency by increasing transaction throughput, enabling miners to process more transactions per block.
With more transactions per block, even if individual transaction fees decrease, miners could still maintain or even increase their overall revenue through a higher volume of transactions. One concern, however, is the potential for reward dilution. As Fractal BTC processes transactions on sub-networks, miners may need to secure and validate transactions on the main chain and fractals. This could result in smaller individual rewards per transaction, as fees and block rewards may need to be split among multiple fractals and the main blockchain. Distributing rewards across different layers may dilute the earnings for miners focused solely on the main BTC blockchain. Additionally, implementing Fractal BTC may lead to changes in block reward structures. Currently, BTC miners are rewarded with a fixed block reward, which halves approximately every four years (known as the BTC halving). As transaction processing becomes more efficient with Fractal BTC, the reliance on transaction fees may increase. If miners find that fees from fractal-based transactions are lower than anticipated, this could further cut their revenue.
Long-Term Outlook for Bitcoin Miners
The long-term impact of Fractal BTC on mining revenues will depend mainly on how the technology is implemented and adopted across the network. If Fractal BTC successfully reduces transaction fees while maintaining a steady flow of transactions, miners could benefit from a more predictable and sustainable revenue model. By processing a significant number of smaller transactions at lower fees, miners can stabilise their income in an environment where block rewards gradually shrink due to BTC’s halving cycles. Moreover, Fractal BTC’s potential to alleviate congestion could increase BTC’s overall adoption and usage, driving more transaction volume across the network.
This increase in demand could offset any losses in transaction fee revenue, ensuring that miners continue to play a vital role in securing the network and validating transactions. However, there is also the risk that miners could see their profits squeezed by increased competition and lower transaction fees. As the blockchain becomes more efficient, miners relying heavily on transaction fees during network congestion may need help adapting to the new system. In this scenario, mining pools may need to become more efficient and scale up their operations to remain profitable, further centralising mining activities and potentially threatening BTC’s decentralised ethos. Fractal BTC presents opportunities and challenges for the mining community. While it offers the potential for more efficient transaction processing and increased transaction volume, it also carries the risk of lower fees and diluted rewards. The impact on mining revenues will depend on how well the technology is integrated into the existing BTC network and how miners adapt to transaction processing and reward structure changes.
Fractal BTC is a promising solution to BTC’s scalability issues, but its impact on mining revenues remains to be determined. On the one hand, it could lead to increased transaction throughput and greater adoption of the BTC network, which may benefit miners in the long run. On the other hand, lower transaction fees and the potential dilution of rewards across fractal networks could negatively affect mining profitability. As technology develops, miners must adapt to these changes and find new strategies to maintain revenue in an evolving ecosystem. Whether Fractal Bitcoin ultimately proves to be a boon or a bane for mining revenues will largely depend on its implementation and miners’ ability to capitalise on the opportunities it presents.
