BTCB2挖矿指南：BIP-110分叉、ASIC矿机和矿池

状态说明：本文反映的是截至 2026 年 9 月 8 日核实的公开信息。该网络尚处于发展初期，其软件、算力、矿池、市场和经济状况可能会快速变化。

BTCB2 mining refers here to mining the independent BLAKE2b chain that emerged from the BIP-110 split. AlphaPool 使用 BTCB2 as the ticker for its payouts on this highly experimental Bitcoin branch. Other sites use labels such as BTC BLAKE2b, so naming is not yet uniform. BTCB2 is not BTC on Bitcoin’s SHA-256 network.

That distinction also applies to the proposal itself. The original BIP-110 proposal did not replace Bitcoin’s mining algorithm. Instead, it proposed a temporary soft fork that limited certain data fields. Only the later breakaway chain moved from SHA-256d to BLAKE2b.

这种区别对每个矿工都至关重要。比特币 S19 或 WhatsMiner 矿机无法简单地切换矿池来挖这条链。而一些较老的 Sia ASIC 矿机无需更新固件即可连接。然而，硬件兼容性并不能保证该币种具有流动性、盈利能力或低风险。

本篇 BTCB2 mining guide explains the split, the algorithm change, compatible miners, available pools, and the checks to complete before mining.

BIP-110 是一个软分叉提案，而不是一种新的挖矿算法。

最初的BIP -110 规范名为“减少数据临时软分叉”。它的目标是在激活后大约一年内限制共识层中某些形式的任意数据。

该提案保留了比特币的 SHA-256d 工作量证明机制。因此，BIP-110 信号机制和后来的 BLAKE2b 链不应被视为同一技术事件。

矿工对拟议激活方案的支持率一直很低。因此，执行 BIP-110 的分支落后于主流比特币链。支持者随后继续维护一条独立的链，并引入了永久性的工作量证明机制变更。至此，该项目从临时的软分叉规则集转变为硬分叉链。

BIP-110 分叉如何改变了其挖矿算法

根据该链的技术参考资料，该分支共享比特币历史记录，一直到区块 961,631。它使用 SHA-256d 算法，直到区块 961,639。从区块 961,640 开始，它永久切换到 BLAKE2b 算法，并采用新的 164 字节头部格式。

这一变化会产生以下几个直接影响：

• SHA-256 比特币 ASIC 无法为新链生成有效的工作量证明。
• BLAKE2b 和许多 BLAKE2b-Sia 设备可以通过兼容的池软件参与。
• 新链不再共享比特币庞大的 SHA-256 安全预算。
• 当算力较低时，挖矿难度、区块生成时间和挖矿收益可能会持续波动。

目标区块间隔仍为 600 秒。然而，目标并非绝对保证。在规模较小的新网络上，算力的突然变化可能会导致难度调整之间区块生成速度异常快或异常慢。

Which ASIC Miners Can Mine BTCB2？

Evidence reviewed September 8, 2026. This is a review of published project, pool and hardware information. No BT-Miners miner connection, accepted-share, credited-reward or payout test is claimed.

Compatibility labels: BT-Miners tested requires an identifiable store test record; Pool/project-listed means the exact model is named in current documentation; Pending verification means only algorithm or specification evidence is available; Not compatible requires explicit conflicting hardware/protocol evidence. No device in this review is labeled BT-Miners tested.

HS models require their Sia mode. Do not compare Handshake-mode hashrate or power with Sia-mode values. BLAKE2s and BLAKE3 are distinct algorithms, not substitute BTCB2 modes.

该连锁店的 矿工指南 names the Goldshell SC5 Pro and Goldshell SC Lite among its examples. B2Pool also publishes a broader 工作硬件列表.

下表对比了实际应用中的候选产品。规格参数为标称值，可能因批次、型号、使用条件和固件版本而异。

这些是额定规格，而非此分支的实际测量值。B2Pool 的硬件页面目前将 BM-S3 和 BM-S3+ 归为同一类，使用相互矛盾的 4.4 TH/s 数据；表格使用的是上面链接的各个产品的具体规格。产品链指南中列出的是 Goldshell 型号，而 AlphaPool 则明确列出了 BM-S3+。请确认每个设备的具体固件版本和可接受的份额数量。

Efficiency should guide the first screening. For example, the BM-S3+ has lower rated energy consumption per terahash than the SC Lite, but requires substantially more total power. Nevertheless, expected revenue cannot be calculated reliably from efficiency alone. A miner also needs the live network difficulty, block reward, pool fee, uptime, coin price, and a credible route to sell or use the reward.

A Closer Look at the Five ASIC Candidates

Product photos above are reproduced from the corresponding BT-Miners listings. Some listings share enclosure photography; images are illustrative and do not verify the exact batch, firmware, or BTCB2 compatibility. Ratings shown are nominal; follow each model link for current listing details.

Goldshell SC5 Pro II vs. SC5 Pro

此 SC5 Pro II is rated at 14 TH/s and 3,300 W, compared with 11 TH/s and 2,820 W for the SC5专业版 in default mode. Calculated from those ratings, the Pro II offers about 27% more hashrate while drawing about 17% more power, with roughly 8% less energy consumed per terahash. These are specification-based comparisons, not measured results or a profitability forecast for this fork.

For a power-constrained setup, the SC5 Pro’s listed low-power mode is another option: 8.8 TH/s at 2,020 W, or approximately 230 J/TH calculated from those ratings. That reduces total power demand and slightly improves nominal efficiency versus the Pro II’s listed mode, at the cost of lower hashrate. Compare the exact operating mode, electricity cost, purchase price, and available circuit capacity before choosing.

Both product pages identify Blake2b-Sia hardware. The chain’s miner guide explicitly names the SC5 Pro, but we have not independently verified accepted shares or payouts from an SC5 Pro II on this fork. Treat the Pro II as a candidate pending confirmation from the pool and a small-scale test of the exact firmware, Stratum endpoint, accepted shares, and payout process. The Siacoin pool links on a product page do not establish support for this separate BIP-110 chain.

哪些比特币矿工无法挖矿？

像蚂蚁矿机 S19、S21、T21 和 WhatsMiner M50 或 M60 系列这样的比特币专用集成电路矿机使用 SHA-256d 算法。它们无法通过固件切换来挖掘 BLAKE2b 分叉版本。因为它们的哈希电路是为不同的功能而设计的。

同样，Blake2s 和 Blake256 算力机器并非自动兼容。名称相似并不意味着它们使用相同的 PoW（工作量证明）实现。在连接任何租用或拥有的算力之前，请务必确认具体的算法和矿池协议。

BTCB2 Mining Pools: B2Pool vs. AlphaPool

截至事实核查日期，本次审查发现有两个公开的矿池网站宣传支持挖矿。本次审查仅针对其公布的条款，并非实际挖矿或收益测试，也并非完整的矿池目录。

B2Pool now advertises TIDES for shared mining: rewards follow a rolling work window. Its published fee is 1% and only the subsidy is shared. This supersedes the earlier PROP description. The site retains some older round-based language; confirm its current accounting and completed payouts before scaling. Solo mining remains a separate, high-variance choice.

AlphaPool 宣传其 PPLNS 服务，收取 2.5% 的费用，以及 0.01 的佣金。 BTCB2 最低支付金额以其特有的符号表示。它列出了 BM-S3+ 和其他 Sia 固件 ASIC 的 7777 端口。其页面还保留了早期发布阶段的措辞。因此，在投入实际算力之前，请务必确认实时设置和已完成的支付。矿池符号标签并不代表实际奖励。 BTC 在 SHA-256 网络上。

通过 OCEAN/DATUM 进行的历史 BIP-110 信令并不能证明当前 BLAKE2b 矿池支持该协议。该链的矿工指南描述的是一个支持 BLAKE2b 的节点，该节点使用 CONVOY DATUM，并支持单人挖矿。在将任何矿池视为兼容之前，请务必确认其与当前链的明确支持。

Is BTCB2 Mining Profitable?

目前尚无足够成熟的市场数据来做出负责任的概括性结论。首要问题不是“哪个矿工赚得最多？”，而是“能否在不造成不可接受风险的情况下对开采出的资产进行估值和出售？”

购买硬件之前，请检查以下六项：

1. 确认链尖正在前进，并且有独立勘探人员也认同这一结论。
2. 核实最近的奖池冻结情况、派彩记录、费用和最低派彩规则。
3. 确定实际市场情况、存款支持、取款支持、深度和价差。
4. 计算电费时应根据墙内功耗，而不能仅凭广告宣传的算力。
5. 使用专门用于分叉链的新钱包和地址。
6. 先进行小规模测试，确认可支付的金额后再扩大规模。

每日能量消耗的粗略计算公式很简单：

daily electricity cost = power in kW × 24 × electricity price per kWh

例如，一台 950 瓦的 SC Lite 泳池每天的成本为 2.28 美元，电费为每千瓦时 0.10 美元。一台 3,400 瓦的 BM-S3+ 泳池每天的成本为 8.16 美元。这些数字不包括冷却费用、泳池使用费、停机时间、维修费用和购置成本。

结语

BIP-110 的故事现在分为两个不同的阶段。首先是一个临时的精简数据软分叉提案，保留了 SHA-256d 算法。在该提案未能获得矿工的广泛支持后，一个独立的分支在区块高度 961,640 采用了 BLAKE2b 算法。

BTCB2 mining creates a possible second use for BLAKE2b-Sia ASICs. Among the five candidates compared here, the iBeLink BM-S3+ has the lowest rated energy consumption per terahash. The Goldshell SC Lite offers a lower-power way to test, while the SC5 Pro and SC5 Pro II provide additional options at higher total power levels, subject to model-specific compatibility checks.

For now, the largest risks are not hardware related. They are network security, software maturity, pool concentration, exchange support, liquidity, and rapid difficulty changes. Treat BTCB2 / BIP-110 fork mining as an experimental deployment until the chain and its markets establish a longer record.

常见问题解答 (FAQs)

什么是 BTCB2, and is it the same as Bitcoin?

BTCB2 is the ticker used by AlphaPool for coins on the independent BLAKE2b hard-fork chain discussed in this guide. It is not BTC on Bitcoin’s SHA-256 network. The original BIP-110 document described a temporary soft fork; the later chain changed proof of work and became a separate hard-fork network. Always verify the supported network before using a wallet, pool, or trading service.

Antminer S21 可以挖 BIP-110 分叉币吗？

不。S21 计算的是 SHA-256d。当前的 BIP-110 分支要求使用 BLAKE2b 工作量证明。

Can Siacoin miners mine BTCB2？

Some exact models are named by pools or the project. Others remain pending verification. Algorithm matching alone does not verify firmware, accepted shares or payouts.

哪 BTCB2 mining pool is best?

B2Pool 和 AlphaPool 的手续费和奖励方式各不相同。本文并未对二者的可靠性进行排名。选择前，请比较延迟、已完成的支付、当前算力和手续费。

我应该只为了这个分支买一台矿机吗？

这是一个高风险的决定。购买前务必确认流动性、收益情况、游戏难度、电力成本以及硬件的备用用途。
