比特幣挖礦難度達到歷史新高,但預計8月將下降

比特幣的挖礦難度對於礦工的盈利能力以及確保比特幣不會比協議允許的速度更快地被挖掘至關重要。

本週,比特幣挖礦難度達到127.6萬億的歷史新高,但預計在下次的難度調整中(8月9日)將會下降。根據CoinWarz的數據,挖礦難度預計將下降約3%,降至123.7萬億,而當前的平均區塊時間約為10分鐘20秒。

CryptoQuant的數據顯示,6月時挖礦難度有所下降,並在7月的前兩週出現了劇烈的下降,難度降至116.9萬億。然而,難度在7月下半月恢復了長期的上升趨勢。

比特幣挖礦難度以及網絡的哈希率(即為保護網絡而投入的總計算能力)對於礦工的盈利能力和維持比特幣的高存量流量比率至關重要,這一比率保護比特幣的價格不會因為過度生產而下跌。

比特幣的難度調整與存量流量比率

存量流量比率衡量的是金融資產或商品的總可用供應量與礦工或商品生產者所新增供應量之間的關係。比率越高,資產或商品對於因過度生產而引起的價格變動的抵抗力越強;比率越低,資產或商品將越容易受到新供應的影響。

這一比率部分解釋了為何白銀被金子取代。白銀的存量流量比率低於金子,白銀價格上升會吸引礦工和生產者增加供應,從而使市場充斥新白銀,壓低價格。

比特幣的存量流量比率高於金子,約94%的比特幣供應(2100萬枚)已經被挖掘並在市場上流通。相比之下,金子沒有硬性供應上限,年通脹率約為2%。

根據PlanB的說法,「金的稀缺性,存量流量比率約為60,而比特幣的稀缺性約為120。因此,比特幣的稀缺性是金子的兩倍。」這一難度調整使得比特幣的價格對生產不敏感,保持與礦工投入的總計算能力成比例。

調整難度可以防止過度生產及隨後因大量新供應短時間內進入市場而導致的價格崩潰。

隨著越來越多的計算能力被投入到保護比特幣網絡中,難度會隨之上升,以保持區塊生產接近協議的10分鐘目標。相反,如果計算能力下降,網絡難度會調整下降,以確保新區塊以穩定的約10分鐘的速度被挖掘。

這篇文章提供了一個關於比特幣挖礦難度調整的重要見解,特別是在當前市場環境中,這一調整對於維持比特幣的價值和穩定性至關重要。隨著挖礦難度的上升,礦工的盈利能力受到挑戰,這可能會導致一些小型礦工退出市場,從而影響整體的網絡安全性。未來,如何平衡挖礦難度與市場需求將是一個重要議題,尤其是在比特幣價格波動的情況下。這也反映了比特幣作為數字資產的獨特性,與傳統資產相比,其供應的稀缺性和調整機制使其在投資者眼中更具吸引力。

Promte ✅ 

A hyper-realistic night portrait of a handsome young man leaning casually against a black luxury car, laughing heartily with head tilted slightly back. He has a groomed beard, short styled dark hair, and is wearing a plain black long-sleeve crewneck sweatshirt. The lighting is low-key and cinematic, with the subject's face warmly illuminated against the darkness. The background features a dark street with beautiful, creamy golden bokeh orbs from distant streetlights and car headlights. Shot on a Sony A7R IV with an 85mm f/1.4 lens, shallow depth of field, sharp focus on the smile, high contrast, moody urban night atmosphere, 8k resolution. Size 4:5 ratio 100% use my upload reference image Prompt:
Use my image in Ultra-realistic, hyper-detailed, 8K cinematic portrait of a young stylish man, using the uploaded image for exact face and hairstyle.
Outfit: An oversized red knit sweater with white hearts, exactly as described in the prompt.
Pose: A hyper-realistic close-up portrait with a messy, cropped framing showing only the boy holding the book. His left hand rests on the wooden table and covers part of his cheek, with a subtle smile on his lips. His other hand holds the book titled "Something I Never Told You" with the word "YOU" written in pink, exactly as
described in the prompt. Background: Not specified. Base Setup
keep 100 percent facial information adherence of the attached image and turn her into a lone night hiker standing in the shallow river at the mouth of the canyon, captured as a live action photograph or movie still, not an illustration or CGI render, with an alluring, confident, quietly sexy mood.

Shot and Camera
Three quarter body shot from slightly low height on the riverbank, placing her on the left third while the water leads into the dark canyon and the star filled sky dominates the top of the frame, preserving the original wide vertical composition.

Identity and Pose
She has a slim athletic build, natural proportions, medium length loose hair, and lightly tanned skin, 8k Photorealistic and hyper realistic. She stands barefoot in the water with one leg forward, hips relaxed, wearing a fitted cropped technical top and separate high waisted trail shorts with an open lightweight jacket slipping off one shoulder, one hand loosely holding a headlamp at her side and the other brushing hair from her face as she looks up at the stars.

Lighting and Environment
Keep the soft starlight and faint glow from the distant horizon, giving a gentle rim on her shoulders and hair while a subtle fill from the reflected sky reveals her features. The canyon walls, river reflections, pebbled shore, and dense star field stay exactly like the reference, with small ripples around her feet grounding her in the water.

Masking and Constraints
Change only by adding the subject and her outfit, keep lighting, perspective, white balance, canyon geometry, and river reflections the same, with realistic scale, body proportions, and clear contact between feet and water surface. Change only the requested element and keep lighting, perspective, white balance, pose, face geometry, body proportions, and silhouette the same, and absolutely avoid added text, painterly or toon styling, CGI look, blown highlights, banding, plastic skin, overly tidy backgrounds, or floating feet while requiring consistent perspective, consistent white balance, subtle film like grain, and physically correct contact shadows and reflections.
