Nostr 协议生态应用有关的闪电网络使用攻略。

Nostr 的出现带火了 Web3.0 社交， 其首个客户端 Damus 在推特创始人 Jack Dorsey 的推荐下，推出不足 2 天就登上美区 App Store 免费社交 App 前十排行榜。Damus 也趁热打铁，在自家应用程序内发起了小额 BTC 随机打赏活动。只要用户在特定的帖子下面发起打赏请求，就有机会获得几美元的打赏。

⠀

不少读者对于闪电网络或许还不熟悉，比特币钱包的科普和使用近些年来并没有像其他领域的内容一样被广泛流传。因此本文结合慢雾科技创始人 Cos（余弦）在推特上发表的关于闪电网络的科普内容，教大家如何通过闪电网络在 Damus 内发起小额打赏。

⠀

以下为 Cos（余弦）发布的闪电网络科普内容

⠀

下面这张图片展示了 4 个选项，每个选项代表一个地址，你能猜到哪个是比特币闪电网络的地址码？Keystone 硬件钱包产品经理给出了答案，我对答案进行了优化。

⠀

⠀

如图这些地址是什么？

⠀

答案如下：

⠀

A. Lightning Invoice(LNURL)

⠀

B. BTC Taproot Address

⠀

C. lndhub wallet backup

⠀

D. Lightning Address

⠀

发现许多人对此感兴趣，这里我展开说点，顺带我也稍微聊聊与 Nostr 协议生态应用有关的闪电网络使用攻略。

⠀

需要注意，C 可是「私钥」般的存在，千万别发出来。 D 这个地址可读性非常高，可以作为你闪电网络的持续收款地址，你可以在 http://lightningaddress.com 选择你喜欢的域名后缀。 另外，A 是你的闪电网络一次性收款的 Invoice 地址，收款后就失效。

⠀

用 Nostr 协议上的应用 Damus 举例，你可以在你的个人页面 -> 右上角 Edit -> BITCOIN LIGHTNING TIPS 填入 D 或 A 地址。 也可以直接把 A 地址发 POST，就可以看到闪电网络求打赏效果了，只是这种收款只能收一笔，毕竟 A 地址是一次性的。

⠀

闪电网络钱包我主要使用 bluewalletio，看个人习惯，如果你在 damusapp交互闪电网络支付时会看到支持的闪电网络钱包还挺多的。

⠀

⠀

这些攻略碎片我前面也有简单说说，发现许多人可能还不清楚，这里就顺便完整一谈了，欢迎转发。 最后，我还是继续强调下，对于陌生的生态先谨慎熟悉熟悉，避免资产损失。

⠀

如何在 Damus 内发起支付请求？BlockBeats 整理并撰写如下

⠀

本教程假设用户尚未拥有比特币钱包。

⠀

根据上述整理，需要找到一款支持闪电网络的比特币钱包，这里我们以余弦常用的 bluewalletio 为例。通过官方渠道下载之后，创建一个新的「Lightning」钱包，点击「Creat」后会自动生成一个二维码和 Indhub 开头数字（上文提到的 lndhub wallet backup，类似私钥一般的存在），请一定妥善保管二维码或在记录下来 Indhub 开头的数字内容。 随后点击「OK，I save it」之后，我们就已经拥有了一个闪电网路钱包了。

⠀

⠀

随后我们进入钱包，点击左下角的「Receive」，然后进入创建 Invoice 的页面，我们在上方蓝字处输入我们想要收到的 Sats 金额。

⠀

（BlockBeats 注： Sats 是 BTC 最小单位 satoshis 的缩写。satoshi 源自比特币创建者中本聪（Satoshi Nakamoto）化名。一个 satoshi（sat）等于 0.00000001 BTC）

⠀

这里我们试试 15000Sats，点击「reate Invoice」。稍作等待后就会出现一个新的二维码和以 Inbc 开头的地址。

⠀

⠀

我们复制下来这个 Inbc 开头的地址后打开 Damus，找到 Damus 的官方账号，在这个贴子下回复我们刚刚复制的地址，Damus 会自动展示成下图模样。该活动支持持续了一段时间，官方没有给出结束时间。作为引流的强效手段，后续不排除 Damus 还会推出类似的互动环节。

Ceasefire Drama Escalates—Trump Points Finger At Iran, Bitcoin In Focus

Iran's Foreign Ministry accused the U.S. of committing war crimes through an unlawful naval blockade, citing violations of the UN Charter and a 1974 resolution. President Trump, meanwhile, claimed Iran fired shots in the Strait of Hormuz, breaching the ceasefire. Both sides blamed each other for escalating tensions. Bitcoin reacted immediately, dropping from $76,250 to $75,400 amid the news, reflecting the market's sensitivity to the conflict. Earlier volatility occurred when Trump announced—and Iran denied—a nuclear deal suspension. The Strait of Hormuz remains a critical flashpoint, with markets closely monitoring whether negotiations will hold or collapse.

Geopolitical Risks Persist, Bitcoin Becomes a Key Barometer?

Amid escalating geopolitical tensions in the Middle East, particularly around Iran and the Strait of Hormuz, and a sudden injection of nearly $200 billion in liquidity by the Federal Reserve and the U.S. Treasury, financial markets are caught in a tug-of-war between liquidity-driven gains and risk-off sentiment. Bitcoin is emerging as a key indicator in this environment due to its high sensitivity to liquidity shifts. It has historically acted as a leading signal—declining ahead of equity downturns and recovering before broader markets. Currently, its ability to break above the $80,000–$85,000 resistance level will test whether recent liquidity injections can outweigh geopolitical uncertainties. Failure to do so may signal underlying weaknesses, potentially in private credit or fading liquidity impact. Other indicators show mixed signals: The CNN Fear & Greed Index reflects greed, volatility indices are relatively calm, and major equity indices like the S&P 500 and Nasdaq have hit new highs. However, the situation remains fragile, with Iran-related risks capable of swiftly reversing sentiment. The key question is whether liquidity or geopolitical risk will dominate market pricing in the near term.

2026 U.S. Stock Cryptocurrency Sector: Opportunities, Risks, and Allocation Framework

U.S. Crypto Investment Landscape in 2026: Summary Since the SEC's historic approval of Bitcoin spot ETFs in January 2024, the U.S. crypto investment sector has matured significantly. By 2026, investors have four primary channels: spot ETFs, crypto equities (miners and treasury companies), leveraged/inverse ETFs, and blockchain funds. A key trend is the rise of dedicated Ethereum treasury companies, exemplified by Bitmine Immersion Technologies (BMNR). Unlike Bitcoin treasuries, ETH treasuries can generate native yield through staking, creating a distinct business model. Bitcoin spot ETFs dominate with $86.9B in assets (as of March 30, 2026), led by BlackRock's IBIT. Ethereum ETFs, like BlackRock's ETHA, hold ~$18B. BMNR holds 4.8M ETH (~$10.8B), representing 3.98% of the supply, and generates ~$196M in annual staking revenue. The 2025 GENIUS Act established a federal stablecoin framework, and major banks are now permitted to offer crypto custody, signaling full regulatory acceptance. A suggested allocation framework (not advice) includes: Core (1-5% in IBIT/ETHA), Industry Beta (2-5% in BKCH/BLOK), Yield/Alpha (0.5-2% in BMNR/MSTR), and Tactical (leveraged products for short-term use only). Key risks include extreme volatility, ETH slashing risks, and the decay of leveraged products. Investors should consult a professional advisor.

Anthropic's One Trillion vs. DeepSeek's 10 Billion

In April 2026, Anthropic's implied valuation briefly surpassed $1 trillion in secondary markets, despite its last official valuation being $380 billion. Its annualized revenue surged to $30 billion, largely driven by enterprise adoption of Claude Code. However, OpenAI accused Anthropic of inflating revenue by $80 billion through gross accounting. Anthropic is not expected to be profitable until 2027. Meanwhile, DeepSeek, after three years of rejecting external funding, announced its first fundraising round targeting a valuation over $10 billion. Founder Liang Wenfeng had prioritized independence and research over capital, citing chip shortages as a bigger constraint than funding. The move aims to address talent retention challenges and potential shifts toward commercialization. Both companies represent different AI philosophies: Anthropic’s closed-source, enterprise-focused model contrasts with DeepSeek’s open-source, research-driven approach. Each faces core challenges—Anthropic must justify its valuation with eventual profits, while DeepSeek must balance growth with its founding vision amid new investors.

Vitalik's Full Speech at the 2026 Hong Kong Web3 Carnival

In his keynote speech at the 2026 Hong Kong Web3 Carnival, Ethereum co-founder Vitalik Buterin outlined the platform’s vision as a "world computer" and detailed its technical roadmap for the next five years. Buterin emphasized Ethereum’s two core functions: serving as a public bulletin board where applications can publish verifiable data, and enabling shared computational objects like tokens, NFTs, and DAOs. He stressed the importance of Ethereum lies in its ability to provide self-sovereignty, verifiability, and permissionless participation without relying on trusted third parties. He discussed the evolution of Layer 2 solutions, arguing that meaningful L2s should complement Ethereum by integrating necessary off-chain components—such as oracles or privacy protocols—rather than simply scaling through centralization. Key short-term goals include scaling data availability and computational capacity through initiatives like increasing the gas limit and deploying zkEVM for more complex, verifiable computations. Buterin also highlighted ongoing efforts to improve quantum resistance, privacy, and efficiency through proposals like EIP-8141 for account abstraction and quantum-safe signatures. Long-term, Ethereum aims to maximize security and decentralization through formal verification, AI-assisted proof generation, and a hybrid consensus model combining Bitcoin’s longest-chain rule with BFT-style finality. The goal is a robust, easily verifiable platform that supports a wide range of applications—from finance and identity to decentralized social networks—while ensuring long-term resilience and trustlessness.

What is $BITCOIN

DIGITAL GOLD ($BITCOIN): A Comprehensive Analysis Introduction to DIGITAL GOLD ($BITCOIN) DIGITAL GOLD ($BITCOIN) is a blockchain-based project operating on the Solana network, which aims to combine the characteristics of traditional precious metals with the innovation of decentralized technologies. While it shares a name with Bitcoin, often referred to as “digital gold” due to its perception as a store of value, DIGITAL GOLD is a separate token designed to create a unique ecosystem within the Web3 landscape. Its goal is to position itself as a viable alternative digital asset, although specifics regarding its applications and functionalities are still developing. What is DIGITAL GOLD ($BITCOIN)? DIGITAL GOLD ($BITCOIN) is a cryptocurrency token explicitly designed for use on the Solana blockchain. In contrast to Bitcoin, which provides a widely recognized value storage role, this token appears to focus on broader applications and characteristics. Notable aspects include: Blockchain Infrastructure: The token is built on the Solana blockchain, known for its capacity to handle high-speed and low-cost transactions. Supply Dynamics: DIGITAL GOLD has a maximum supply capped at 100 quadrillion tokens (100P $BITCOIN), although details regarding its circulating supply are currently undisclosed. Utility: While precise functionalities are not explicitly outlined, there are indications that the token could be utilized for various applications, potentially involving decentralized applications (dApps) or asset tokenization strategies. Who is the Creator of DIGITAL GOLD ($BITCOIN)? At present, the identity of the creators and development team behind DIGITAL GOLD ($BITCOIN) remains unknown. This situation is typical among many innovative projects within the blockchain space, particularly those aligning with decentralized finance and meme coin phenomena. While such anonymity may foster a community-driven culture, it intensifies concerns about governance and accountability. Who are the Investors of DIGITAL GOLD ($BITCOIN)? The available information indicates that DIGITAL GOLD ($BITCOIN) does not have any known institutional backers or prominent venture capital investments. The project seems to operate on a peer-to-peer model focused on community support and adoption rather than traditional funding routes. Its activity and liquidity are primarily situated on decentralized exchanges (DEXs), such as PumpSwap, rather than established centralized trading platforms, further highlighting its grassroots approach. How DIGITAL GOLD ($BITCOIN) Works The operational mechanics of DIGITAL GOLD ($BITCOIN) can be elaborated on based on its blockchain design and network attributes: Consensus Mechanism: By leveraging Solana’s unique proof-of-history (PoH) combined with a proof-of-stake (PoS) model, the project ensures efficient transaction validation contributing to the network's high performance. Tokenomics: While specific deflationary mechanisms have not been extensively detailed, the vast maximum token supply implies that it may cater to microtransactions or niche use cases that are still to be defined. Interoperability: There exists the potential for integration with Solana’s broader ecosystem, including various decentralized finance (DeFi) platforms. However, the details regarding specific integrations remain unspecified. Timeline of Key Events Here is a timeline that highlights significant milestones concerning DIGITAL GOLD ($BITCOIN): 2023: The initial deployment of the token occurs on the Solana blockchain, marked by its contract address. 2024: DIGITAL GOLD gains visibility as it becomes available for trading on decentralized exchanges like PumpSwap, allowing users to trade it against SOL. 2025: The project witnesses sporadic trading activity and potential interest in community-led engagements, although no noteworthy partnerships or technical advancements have been documented as of yet. Critical Analysis Strengths Scalability: The underlying Solana infrastructure supports high transaction volumes, which could enhance the utility of $BITCOIN in various transaction scenarios. Accessibility: The potential low trading price per token could attract retail investors, facilitating wider participation due to fractional ownership opportunities. Risks Lack of Transparency: The absence of publicly known backers, developers, or an audit process may yield skepticism regarding the project's sustainability and trustworthiness. Market Volatility: The trading activity is heavily reliant on speculative behavior, which can result in significant price volatility and uncertainty for investors. Conclusion DIGITAL GOLD ($BITCOIN) emerges as an intriguing yet ambiguous project within the rapidly evolving Solana ecosystem. While it attempts to leverage the “digital gold” narrative, its departure from Bitcoin's established role as a store of value underscores the need for a clearer differentiation of its intended utility and governance structure. Future acceptance and adoption will likely depend on addressing the current opacity and defining its operational and economic strategies more explicitly. Note: This report encompasses synthesised information available as of October 2023, and developments may have transpired beyond the research period.
