BTC、BCH和BSV 之间的比较

金色财经Опубліковано о 2024-07-08Востаннє оновлено о 2024-07-08

BTC在几年前区块容量逐渐接近上限之时,已经就扩容问题讨论许久,矿工、开发人员、用户之间的博弈相对混乱,在谈不拢的情况下,分叉成为唯一的结局。

于是,在 2017 年 8 月 1 日从 BTC 中分叉出 BCH,将区块大小从 1M 提升至 8M,号称自己才是中本聪“点对点电子现金系统”的真正体现。2018 年 11 月 15 日,BCH 内部再次因为 BCH 的未来发展方向出现分歧,导致 BCH 分裂为比特大陆系 BCHABC(前者后来拿回 BCH 称号)与 Nchain 系 BCHSV(后来命名为 BSV)。

至此,比特币终于形成三国鼎立之势。BTC 电子黄金、BCH 电子现金和 BSV 全球账本。接下来的篇章,将探讨它们之间的主要区别:

BTC

BTC 的区块链是创始 BTC 的原始区块链,它的第一个区块被称为创世区块,创建于 2009 年 1 月 3 日。

初始时,每个区块的新币奖励为 50 BTC,但在产生超过 21 万个区块后,系统奖励将减半。目前,每隔约十分钟产生一个区块,而总供应量限定在 2100 万 BTC。

根据当前的产生速率,BTC 估计将在大约 2140 年时几乎发行完所有的 BTC。

BCH

BCH 于 2017 年 8 月 1 日的区块高度 #478558 上发生了硬分叉,按照比特币1:1分发,总量 2100 万,删除隔离见证、区块上限升级为 8M,后升级为 32M,通过链上扩容解决了旧版比特币系统中手续费高、确认慢、实用性差等问题,履行比特币作为「点对点电子现金」的承诺。

该分叉主要由 Bitmain 以及其他区块链参与者和个人发起,他们认为 BTC 原有的区块大小 (1MB) 不足以支持多样化的商业应用。因此,他们希望扩大每个区块的容量,最初计划在六个月内将其增加到 2 MB,后来又在 2018 年五月将其调整到 32 MB。

在分叉后的几个月,BCH 经历了另一次分叉,分为BCC 和 BCH。之后,新链 BCH 一直保持主导地位,直到 2019 年中,原链 BCC 因大量区块链参与者的投入而重新复苏。

BSV

BSV 于 2017 年 10 月 24 日的区块高度 #491407 上进行了硬分叉。这次分叉是从 BCH 区块链中分叉出来的,形成了 BCH 和 BSV 两个不同的区块链。

分叉的主要原因是关于采用不同的区块链规则的争论,一些人希望回到 BTC 原始的规则。结果,BCH 维持了BCH 的设计,而 BSV 回归了 BTC 原始的设计。分叉的发起者希望通过这一变化,减轻变得过于专业化的问题以及硬件和 ASIC 的垄断。他们希望回归原生 BTC 的 GPU 方式。

在分叉之后,BSV 的开发团队立即释放了 100,000 枚 BSV,其中 95% 用于发展和支持 BSV 的区块链。虽然 BSV 遵循了 BTC 的许多原则,但它采用了稍有不同的工作量证明算法。然而,2018年,BSV 的用户主导了超过 50% 的计算能力,引发了双重支付问题,因此导致了巨额损失。

Domestic First Explosion-Proof Certification, World's First Fueling Brain Solution: How Did They Secure Two 'Firsts'?

China's embodied AI sector is booming, with over ¥37 billion in funding this year. The focus has shifted decisively to real-world application, particularly in hazardous, repetitive tasks humans should avoid. A key, often prohibitive, barrier to entry for robots in environments like gas stations and oil fields is obtaining explosion-proof certification, requiring meticulous hardware and circuit design from the ground up. The article explores three main application areas. At gas stations, the challenge lies in executing a long, precise sequence of actions (opening caps, handling the fuel nozzle) with millimeter accuracy across diverse car models. For facility inspections, robots need sustained autonomous patrols combined with real-time anomaly detection and response. Port scenarios introduce the complexity of multi-robot coordination. Addressing the core challenge of long-horizon tasks, the piece highlights a technical breakthrough: a "world model"-driven approach. This enables predictive planning, allowing the AI to visualize the desired end-state (e.g., nozzle returned, cap closed) and work backward to synthesize intermediate visual frames. This "imagination" of the task trajectory, as implemented in the H-GAR architecture, guides action generation, significantly reducing cumulative error in multi-step operations. The three-step H-GAR process involves generating a coarse action draft, synthesizing target-conditioned observation frames, and then refining actions based on visual context and a memory of past successful motions. The conclusion emphasizes that success in specialized, safety-critical fields requires long-term commitment and deep integration of the "embodied brain" (AI) with a purpose-built, certified physical "body." Mastering this brain-body-data闭环 (closed-loop) is positioned as a crucial competitive advantage for commercialization.

Bitcoin Bear Market Triggers Crypto Layoffs, Yet Fuels Industry's Most Aggressive M&A Wave Ever

A prolonged Bitcoin downturn is forcing crypto companies to lay off employees and automate operations, but has simultaneously triggered the industry's most aggressive wave of mergers and acquisitions (M&A). In the first half of 2026, crypto M&A deal value reached $93.7 billion, 26 times higher than the same period last year. This activity is primarily driven by traditional financial institutions—banks, payment processors, and asset managers—who are acquiring compliant crypto infrastructure like custody solutions, payment rails, and regulatory licenses instead of building them internally. Examples include Mastercard's acquisition of stablecoin firm BVNK and Franklin Templeton's launch of a dedicated crypto division via acquisition. This consolidation contrasts sharply with a shrinking crypto labor market, where active job openings have plummeted. Companies like Coinbase are restructuring to become "AI-native," leading to a sharp increase in roles requiring AI skills, while engineering and compliance positions now dominate hiring. Financially pressured crypto firms, such as Messari which was acquired at a fraction of its prior valuation, are becoming prime targets. Capital remains available but is highly selective, flowing overwhelmingly into businesses that bridge digital assets with traditional finance, such as tokenization platforms and regulated trading venues. The trend indicates a market where capital is rewarding compliant, utility-focused infrastructure while weaker models consolidate or downsize.

Trillion-Dollar Pension Fund Entry? Franklin Bitcoin Dividend Reinvestment ETF Comes with a Built-in Selling Pressure Ceiling

Franklin Templeton has filed to launch two ETFs that embed a "default configuration" logic into Bitcoin investment, aiming to tap into massive pension fund flows. These "Bitcoin Dividend Reinvestment Index ETFs" will initially hold 95% equities and 5% Bitcoin, automatically reinvesting stock dividends to buy Bitcoin. However, a quarterly rebalancing rule forces selling of Bitcoin if its allocation exceeds 5%, capping its maximum holding at 20%. While the product cleverly circumvents advisor reluctance and compliance hurdles by labeling itself as a U.S. equity product, its actual Bitcoin buying power is minimal. Given low dividend yields (e.g., ~1% for broad market indices), annual Bitcoin purchases from a fund the size of Franklin's existing Bitcoin ETF would be a mere $3.6 million—negligible against Bitcoin's daily trading volume. Crucially, during bull markets, the fund becomes a programmed, passive *seller* of Bitcoin, potentially creating sustained sell pressure if many similar funds emerge. The strategy leverages investor inertia and automatic enrollment, similar to the success of target-date funds in 401(k) plans. It also uses an offshore Cayman subsidiary for holding Bitcoin and raises a tax complication where investors must pay taxes on dividends they never receive as cash. Although recent U.S. regulatory changes allow crypto in retirement plans, widespread adoption as a default option faces legal hurdles. The core premise remains: the system doesn't need to convince anyone to buy Bitcoin actively; it simply relies on people doing nothing.
