Bitcoin is based on a peer-to-peer electronic cash system that allows direct transactions between users without financial intermediaries.

2026-08-08 00:40:17 CEST

Private keys provide control over Bitcoin, while losing the private key results in losing the ability to spend the associated coins.

2026-08-08 00:39:26 CEST

In Bitcoin, users do not need permission from a third party to transfer their funds.

2026-08-08 00:39:03 CEST

The principle of “not your keys, not your coins” reflects the idea that true ownership requires control of private keys.

The first lesson of the crypto world: assume everyone is a bad actor. 🙂
Seeing people kidnap others over Bitcoin really makes the world feel like a true cyberpunk reality.
In the past, people robbed cash and gold. Now they target private keys and wallets. Wealth has become a string of seed phrases, and human greed has evolved along with the technology.
Many people thought blockchain would bring more freedom and trust, but the reality is: technology can be decentralized, but human nature cannot.
In cybersecurity, there is a harsh principle: trust no one.
Systems are built assuming attackers exist. Protocols assume someone will try to break them. Security designs assume that good intentions will not last forever.
The most dangerous threat is often not the bad person you know, but the one you never expected to exist.
So don’t assume technology will automatically create a better future. In security, the most basic survival rule is: assume the world can be hostile, and protect yourself.
Technology has not betrayed us. Humans have simply made technology much harder to live with. 🙂

BIP-110 currently has only:
- Miner hash rate support: about 0.31%
- Full node support: about 2%
It cannot become a mainstream Bitcoin rule.
No one supports it.
I recommend that everyone run full nodes that do not support BIP-110 to resist this rule from taking effect.
Full nodes are very important for Bitcoin.

The BIP-110 proposal is causing controversy in Bitcoin: currently only about 0.31% of miner hashpower supports the proposal (around 99.69% of miner hashpower does not support it), and only about 2% of full nodes support it (around 98% of full nodes do not support it). The core debate is whether miners and full nodes should accept the proposed changes to Bitcoin’s rules.

Syncthing is an open-source, free peer-to-peer (P2P) file synchronization tool that can automatically sync folders between multiple devices. Its biggest feature is that it does not rely on a central server. Files are transferred directly between your devices, and data is not stored on third-party cloud services by default.
It supports Windows, Linux, macOS, and Android. The transfer process uses TLS encryption, and devices authenticate each other through certificates, providing a high level of security. Common use cases include syncing photos, notes, and documents between computers and phones, sharing work directories across multiple computers, and synchronizing configuration files between servers.
Simply put: Syncthing can be considered a “private version of Dropbox” that does not depend on cloud providers and allows you to maintain full control over your own data.

China’s population entered a period of natural decline, with deaths significantly exceeding births. The low birth rate indicates continued demographic pressure and an accelerating aging trend.

2026-07-24 01:37:39 CEST

In 2025, China’s total population was 1.40489 billion. During the year, 7.92 million people were born and 11.31 million people died, resulting in a natural population decrease of 3.39 million (11.31 million − 7.92 million = 3.39 million). The number of births was only 70.0% of the number of deaths (7.92 million ÷ 11.31 million = 70.0%).

2026-07-24 01:34:00 CEST

In 2024, China recorded 6.106 million marriage registrations, a year-on-year decline of 20.5%. In the first quarter of 2026, marriage registrations fell further to 1.697 million, down 6.2% year on year, indicating that the marriage market itself is shrinking.
A likely implication is that fewer people will choose to marry, while delayed marriage, remaining single, and lower birth rates are expected to become increasingly common.

1. Technology（科技）
Although technology has made our lives much more convenient by allowing us to access information and communicate with others instantly, I believe we should also be aware of its potential negative effects, such as reduced face-to-face communication and excessive dependence on digital devices.
虽然科技通过让我们能够即时获取信息和交流，使生活变得更加便利，但我认为我们也应该意识到它可能带来的负面影响，比如面对面交流减少，以及对电子设备的过度依赖。
适用：technology, social media, modern life, education
2. Education（教育）
In my opinion, the purpose of education is not only to help students achieve academic success, but also to develop their critical thinking skills, creativity, and the ability to solve real-world problems.
在我看来，教育的目的不仅是帮助学生取得学业上的成功，也是培养他们的批判性思维、创造力以及解决现实问题的能力。
适用：school, teachers, university, learning
3. Environment（环境）
If individuals, companies, and governments work together to reduce pollution and protect natural resources, we can create a more sustainable future for the next generation.
如果个人、企业和政府共同努力减少污染并保护自然资源，我们就能够为下一代创造一个更加可持续的未来。

• Signal: An open-source encrypted messaging app developed by the Signal Foundation. It uses the Signal Protocol to provide end-to-end encryption and supports text messages, voice and video calls, and file transfers. Registration usually requires a phone number, but message and call content cannot be read by the server.
• Session: A decentralized privacy-focused messaging app developed by the Oxen project. It is based on the Session Protocol, does not require a phone number or email to register, uses a decentralized network of nodes (Service Nodes) to relay messages, and protects communications with end-to-end encryption.
Main differences:
* Privacy design: Signal focuses on strong encryption and minimal data collection; Session puts more emphasis on anonymous identity and decentralization.
* Identity method: Signal uses a phone number as the account identifier; Session uses a randomly generated Session ID.
* Maturity: Signal has a larger user base, more security audits, and more real-world usage experience; Session’s anonymity design is more prominent, but its ecosystem is smaller.
Additional note: Session is not simply “the anonymous version of Signal.” Although both use end-to-end encryption principles, their technical architectures and trust models are different.

BNB was not created through mining. Instead, it was pre-issued at the launch of the project. The initial total supply was 200 million BNB, and the supply has since been adjusted through circulation mechanisms and token burns.
Therefore, BNB does not generate new coins through mining like Bitcoin does.

2026-07-23 23:33:53 CEST

BSC does not require mining because it uses the PoSA (Proof of Staked Authority) consensus mechanism instead of PoW (Proof of Work).
Simply put:
BNB was already created through an initial issuance process. Unlike Bitcoin, which relies on miners continuously performing computations to generate new block rewards, BSC relies on validator nodes. Validators stake BNB to obtain the right to produce blocks and maintain network operations.
BNB uses a pre-mint model, meaning the total supply was determined at the time of creation.

2026-07-23 23:32:23 CEST

BSC (BNB Smart Chain) conducts an election process every day after 00:00 UTC. Based on validators’ staking rankings, the top 45 validators are selected as active validators for block production.
Among these 45 active validators, the 21 validators with the highest staked amounts are called Cabinets, while the remaining 24 validators are called Candidates.
Other inactive validators that are not ranked within the top 45 must wait for the next election round. They can only participate in block production after becoming active validators again.
Within the set of 45 active validators, each Epoch selects 18 validators from the Cabinets.

The prisoner’s dilemma describes a situation in which two participants engage in a two-person non-cooperative game. Assume that each participant can choose between cooperation and defection, and that the payoff structure satisfies the following conditions: if one participant cooperates while the other defects, the defector receives the highest payoff, while the cooperator suffers the greatest loss; if both participants defect, they receive an intermediate payoff; and if both participants cooperate, they receive a relatively high payoff, but one that is lower than the payoff obtained by a participant who successfully defects while the other cooperates. Under this structure, neither participant has an incentive to choose cooperation unilaterally, because defection provides a higher payoff regardless of the other participant’s choice. Therefore, both participants ultimately choose defection and reach a Nash equilibrium.

Economic transactions involving goods and services are built upon the foundation of voluntary and mutually beneficial interactions between two parties 🤝. However, when external authorities require both parties to disclose the details of their transactions 🔍, they must seek permission for every action they take 🔒. Individuals can only reclaim their sovereignty 🕊️ by using the tools of self-defense 🛡️ that they possess.
Without financial privacy, there can be no human dignity 🧍‍♂️✨.
Privacy is the process of selectively revealing oneself to others 👤. You have countless thoughts in your mind 💭 that you choose never to share with anyone 🤫; many of your actions are never witnessed by others 👁️. The ability to keep secrets 🔐 is an essential part of the human experience 🌱.

商品和服务的经济交易建立在双方自愿且互利的行为基础上。但是，当外部权威要求交易双方公开交换细节时，他们就必须为每一次行为请求许可。然而，个人可以利用自己拥有的自我防卫工具，重新获得自己的主权。
没有金融隐私，就没有人的尊严。
隐私，是选择性地向他人展现自己的过程。你脑海中有许多想法，你选择永远不告诉任何人；你的许多行为也从未被其他人看到。保守秘密的能力，是人类体验中不可或缺的一部分。

2026-07-23 22:26:50 CEST

我们家窗帘存在的主要原因，是防止别人看到屋内的情况。我们不希望别人看到，是因为我们认为家中的许多行为属于私人领域。无论是在餐桌前吃饭、和孩子一起看电影，还是与伴侣进行亲密或性行为。这些事情都不违法，但即使如此，我们仍然会拉上窗帘、关闭百叶窗。很明显，在个人生活和公众之间，我们拥有强烈的隐私需求。

如果知道助记词的位置，丢几个词到底有多少可能？
以 BIP39 助记词为例：每个词来自 2048 个词的词库。
所以：
丢 1 个词：2048 种可能
丢 2 个词：2048² = 4,194,304 种可能（约 419 万）
丢 3 个词：2048³ = 8,589,934,592 种可能（约 85.9 亿）
丢 4 个词：2048⁴ = 17,592,186,044,416 种可能（约 17.6 万亿）
但是，实际恢复时还需要检查 checksum（校验码）。
以 12 个词的 BIP39 助记词为例：总熵 128 bit，checksum 4 bit。
也就是说，最后一个候选只有约 1/16 的概率通过 checksum。
所以：
丢 1 个词：2048 ÷ 16 ≈ 128 个候选
丢 2 个词：4,194,304 ÷ 16 = 262,144 个候选
丢 3 个词：8,589,934,592 ÷ 16 ≈ 536,870,912 个候选
丢 4 个词：17,592,186,044,416 ÷ 16 ≈ 1,099,511,627,776 个候选
因此：
知道缺失词的位置时：
1 个词：很容易搜索
2 个词：仍然可行
3 个词：约 5.3 亿个有效候选，已经困难
4 个词：超过 1 万亿个有效候选，基本不可行
核心公式：
有效搜索量 ≈ 2048ⁿ ÷ checksum 筛选比例
其中 n = 丢失词数量。

Enter through the narrow gate; for the gate that leads to destruction is wide, and the road is broad, and many walk upon it.
But the gate that leads to life is narrow, and the road is difficult and filled with hardship, and few find it.
Most people choose the path that is easy and aligned with their desires and the trends of society. But the path of truly seeking God is often lonely and restrictive, requiring sacrifice and perseverance.

However, under certain conditions, they can still react with oxygen, acids, halogens, sulfur, or other chemical substances, forming new compounds such as oxides, chlorides, and sulfides.
Gold (Au) is unique because of its extremely low chemical reactivity. Under normal environmental conditions, gold almost does not react with oxygen or water and does not easily form oxides or corrosion products.

2026-07-18 01:40:20 CEST

Common metals usually have much higher chemical reactivity than gold and can react with oxygen, water, acids, bases, or other elements to form new compounds.
Iron (Fe):
4Fe + 3O₂ → 2Fe₂O₃
4Fe²⁺ + O₂ + 4H₂O → 4Fe(OH)₃
2Fe(OH)₃ → Fe₂O₃·3H₂O (rust)
Aluminum (Al):
4Al + 3O₂ → 2Al₂O₃
2Al + 6HCl → 2AlCl₃ + 3H₂↑
2Al + 2NaOH + 2H₂O → 2NaAlO₂ + 3H₂↑
Copper (Cu):
2Cu + O₂ → 2CuO
2Cu + O₂ + H₂O + CO₂ → Cu₂(OH)₂CO₃ (basic copper carbonate)
Cu + S → CuS
Zinc (Zn):
2Zn + O₂ → 2ZnO
Zn + 2HCl → ZnCl₂ + H₂↑
Magnesium (Mg):
2Mg + O₂ → 2MgO
Mg + 2H₂O → Mg(OH)₂ + H₂↑
Silver (Ag):
2Ag + H₂S → Ag₂S + H₂↑
Compared with these common metals, gold (Au) has extremely low chemical reactivity. It does not easily react with oxygen, water, or most acids under normal conditions. Gold does not form common oxides or corrosion products and can remain in its elemental state for thousands of years.
Only highly corrosive chemical environments, such as aqua regia (a mixture of concentrated hydrochloric acid and nitric acid), can dissolve gold:
Au + HNO₃ + 4HCl → HAuCl₄ + NO + 2H₂O
Therefore, gold’s extremely low chemical reactivity and strong resistance to oxidation and corrosion are key reasons why it is classified as a noble metal. 🪙

2026-07-18 01:39:30 CEST

Many common metals have important industrial applications, but their chemical stability is significantly lower than that of gold. Due to differences in atomic structure and electron configuration, different metals have different tendencies to lose electrons and form compounds. As a result, they can react with oxygen, water, acids, bases, and other elements, gradually changing into new chemical substances.
Iron (Fe) is a metal that is highly susceptible to oxidation. In a moist environment, iron reacts with oxygen and water, causing corrosion. The process begins with iron atoms losing electrons and forming ferrous ions:
Fe → Fe²⁺ + 2e⁻
The ferrous ions are then further oxidized by oxygen:
4Fe²⁺ + O₂ + 4H₂O → 4Fe(OH)₃
The resulting iron hydroxide gradually loses water and forms hydrated iron oxide, which is the main component of rust:
2Fe(OH)₃ → Fe₂O₃·3H₂O
These reactions continuously consume metallic iron, weakening the structure of the metal over time.
Aluminum (Al) has relatively high chemical activity. When exposed to air, aluminum reacts quickly with oxygen to form aluminum oxide, which creates a protective surface layer:
4Al + 3O₂ → 2Al₂O₃
Although this oxide layer slows further corrosion, aluminum itself remains chemically reactive. For example, aluminum reacts with hydrochloric acid:
2Al + 6HCl → 2AlCl₃ + 3H₂↑
Aluminum can also react with strong alkaline solutions, such as sodium hydroxide:
2Al + 2NaOH + 2H₂O → 2NaAlO₂ + 3H₂↑
These reactions demonstrate that aluminum still has significant chemical reactivity under certain conditions.
Copper (Cu) is more chemically stable than iron and aluminum, but it can still undergo oxidation and corrosion reactions. When heated in oxygen, copper forms copper oxide:
2Cu + O₂ → 2CuO
When exposed to moist air containing carbon dioxide over a long period, copper can form basic copper carbonate, commonly known as the green patina:
2Cu + O₂ + H₂O + CO₂ → Cu₂(OH)₂CO₃
Copper can also react with sulfur to form copper sulfide:
Cu + S → CuS
Therefore, although copper is relatively stable, it can still gradually transform into new compounds over time.
Zinc (Zn) is another common metal that reacts relatively easily. For example, zinc reacts with hydrochloric acid to produce zinc chloride and hydrogen gas:
Zn + 2HCl → ZnCl₂ + H₂↑
Zinc also reacts with oxygen to form zinc oxide:
2Zn + O₂ → 2ZnO
Magnesium (Mg) has even higher chemical activity. When burned in air, magnesium reacts rapidly with oxygen:
2Mg + O₂ → 2MgO
Magnesium can also react with water under certain conditions:
Mg + 2H₂O → Mg(OH)₂ + H₂↑
Silver (Ag), although considered a precious metal, is still less chemically stable than gold. Silver reacts with hydrogen sulfide in the air to form silver sulfide, which causes silver objects to turn black:
2Ag + H₂S → Ag₂S + H₂↑
In contrast, gold (Au) has extremely low chemical reactivity and is a typical noble metal. Under normal environmental conditions, gold almost does not react with oxygen or water. It does not form oxides like iron, nor does it easily form corrosion products like copper or silver.
Gold is not completely chemically inert, but it requires very special conditions to dissolve. For example, aqua regia, a mixture of concentrated hydrochloric acid and concentrated nitric acid, can dissolve gold. In this highly oxidizing environment, gold is oxidized and forms soluble chloroauric acid:
Au + HNO₃ + 4HCl → HAuCl₄ + NO + 2H₂O
Therefore, gold requires special chemical conditions such as aqua regia to be dissolved. Under natural environmental conditions, gold is extremely resistant to oxidation and corrosion and can remain in its elemental form for very long periods. This extremely low chemical reactivity and high chemical stability are fundamental chemical characteristics that distinguish gold from most other metals.

2026-07-18 01:36:26 CEST

One of the key reasons gold is classified as a precious metal is its extremely high chemical stability. Gold (Au) is a highly inert metal that has very low chemical reactivity under normal environmental conditions. Unlike iron, which easily reacts with oxygen and moisture to form rust, or copper and silver, which can develop surface compounds through oxidation or sulfur reactions, gold remains largely unchanged. This is because the atomic structure of gold makes it difficult for its atoms to lose electrons and participate in chemical reactions. As a result, gold has exceptional resistance to corrosion and can maintain its metallic properties and appearance for hundreds or even thousands of years. 🪙
In addition to its chemical stability, gold is also naturally scarce. The amount of gold available in the Earth’s crust is extremely limited, and its formation requires rare geological processes over very long periods of time. Gold mining and extraction require significant resources and technology, which means its supply cannot be rapidly increased like ordinary materials. This natural limitation creates a unique scarcity that has remained consistent throughout human history. 🌍
The combination of strong chemical stability and natural scarcity gives gold a unique position among materials. It can resist environmental degradation over extremely long periods while remaining difficult to produce or replace. These two fundamental properties are important reasons why gold has maintained its special status as a valuable material across civilizations and generations. ⏳💎

The long-term value of gold comes not simply from being a commodity, but from a combination of unique characteristics that few other assets can match: scarcity, durability, divisibility, portability, and a global foundation of trust built over thousands of years. 🪙🌍
Gold does not depend on the performance of a single company like stocks, nor does it rely entirely on the credit of a specific institution like fiat currencies. Its value comes from limited supply, universal recognition, and its long-established role as a store of value and a monetary asset throughout human history. ⏳💎
Compared with gold, the value of many other assets depends heavily on specific environments, technological paths, or business models. When new technologies emerge and more efficient products are created, older technologies and outdated business models may gradually lose their competitiveness and eventually be replaced. 💻⚙️
The unique feature of gold is that its value does not rely on a particular technology, company, or profit model. Instead, it is supported by its scarcity and the long-term consensus of human society. Time can change many things, but assets with genuine long-term value tend to withstand economic cycles and the test of history. 🌍⌛

黄金之所以长期拥有特殊的价值，并不仅仅因为它是一种商品，而是因为它具备许多其他资产难以同时拥有的特性：稀缺性、耐久性、可分割性、易储存性以及全球范围内长期形成的信任基础。黄金不会像企业股票一样依赖某个公司的经营能力，也不会像法定货币一样依赖单一机构的信用支持。经过数千年的历史积累，黄金逐渐成为全球认可的价值储存工具，其价值来自真实的稀缺供给、广泛的市场共识以及长期稳定的货币属性。🪙🌍
相比之下，许多资产的价值往往依赖于特定环境、技术路线或商业模式。当新的技术出现、更高效的产品被创造出来时，旧的技术和旧的商业模式可能会逐渐失去竞争力，甚至被市场淘汰。💻⚙️ 黄金的特殊之处在于，它并不依靠某一种技术或企业盈利模式生存，而是依靠长期形成的稀缺性和人类社会对其价值的共同认可。时间可能会改变许多东西，但真正具备长期价值基础的资产，往往能够经受周期变化和历史考验。⏳💎

You’re still waiting for a sign to buy Bitcoin.
The sign appeared back in 2009.
Every day since then has been like a flashing neon billboard saying: “BUY NOW.”
You’ve ignored it for 15 years.
How many more signs do you need before you finally act?

High technology does not necessarily have true universal value on a global scale. In many cases, technologies are heavily dependent on local environments, regulations, and ecosystems. Once removed from their original context, their value often decreases significantly.

I’ve been exploring foreign websites and various interesting resources, and I’ve increasingly felt that truly valuable information rarely exists within the boundaries of one’s own language. When you stay within your native-language sphere, most of what you encounter is repetitive, superficial, and lacking in real value, making it difficult to access genuinely meaningful insights.

安迪·杜弗雷因（Andy Dufresne）是波士顿的一名银行家，因被指控谋杀妻子萝丝及其情夫而在 1947 年被判无期徒刑，送入位于缅因州的肖申克监狱。抵达后，他被迫与凶狠的囚犯们同吃同住，却始终保持沉默和冷静。监狱长诺顿（Samuel Norton）和副监狱长哈德利（Hadley）发现安迪精通财务与税务，便让他负责监狱的账目和洗钱业务，期间安迪帮助诺顿将监狱收入隐藏为个人资产，并为哈德利的“黑手党”式贿赂提供财务掩护。凭此，安迪在监狱中获得相对优渥的工作、单人牢房和图书馆的使用权。
在肖申克，安迪结识了在狱中拥有极高威信的老囚犯埃利斯·“瑞德”·雷丁（Ellis "Red" Redding），两人逐渐成为知心好友。瑞德负责在囚犯之间走私香烟、酒精和其他违禁品，安迪则用自己的专业帮助囚犯们申报税务、办理贷款，甚至为监狱官员办理合法的税务减免。安迪利用这些关系，争取到大量外部图书捐赠，重建了监狱图书室。随后，他发起夜校教育项目，帮助囚犯们完成高中文凭（GED），并亲自教授金融与法律基础，使得监狱内部的文化氛围与自尊心显著提升。
然而，安迪从未放弃逃离的念头。他在监狱墙体后方的排水管道里，利用每晚的刮刀与石块慢慢凿出一条通道，整个过程持续约二十年。为了掩盖敲击声，他选择在每年春季的大雨季节进行工作，并把噪音混入排水系统的水流声中。与此同时，他秘密在监狱图书室的墙后挖掘，一边藏匿工具，一边收集碎石以防被发现。1993 年的一个暴风雨之夜，安迪终于完成穿墙，冲进下水道，顺着渠道滑向外界，并在雨夜的狂风中进入一辆预先停放在监狱附近的废弃卡车，携带了诺顿藏匿的 1,000,000 美元现金。
安迪成功逃脱后，先发制人地向媒体曝光了诺顿的腐败与监狱的种种不法行为，使得监狱长自杀，守卫们被捕。随后，安迪在信中约定的地点——墨西哥的太平洋海岸小镇巴哈（Zihuatanejo）留下了另一封信，指引瑞德在假释后前往。1994 年，瑞德在获得假释并完成康复治疗后，依据安迪的指示乘坐巴士抵达巴哈，二人在白色沙滩上重逢。影片在两人背对夕阳、举手相拥的画面中结束，象征无论身处何种绝望，友谊、坚持与希望总能指引人们走向自由。

Serpent-256:
32-round SPN
→ Designed with the largest security margin
AES-256:
14-round SPN
→ High security margin, but designed with a stronger emphasis on efficiency and balance
Twofish-256:
16-round Feistel structure
→ Complex structure, with a relatively high security margin as recognized during NIST’s evaluation
Camellia-256:
24-round Feistel structure (including FL/FL⁻¹ layers)
→ Features a strong security-oriented design
Kuznyechik-256:
10-round SPN
→ Strong round structure, but with fewer rounds
Assuming we only consider cryptographic design, without considering speed, hardware acceleration, or practical usability, which one is most like building the thickest vault?
Serpent-256
From the perspective of “how far the cipher is from being broken by cryptanalysis,” Serpent has a noticeably more conservative security margin.

Serpent-256：
32 轮 SPN
→ 最大安全余量设计
AES-256：
14 轮 SPN
→ 安全余量较高，但设计更偏向效率和平衡
Twofish-256：
16 轮 Feistel
→ 结构复杂，安全余量也被 NIST 评价为较高
Camellia-256：
24 轮 Feistel（包含 FL/FL⁻¹ 层）
→ 具有较强安全设计
Kuznyechik-256：
10 轮 SPN
→ 每轮结构较强，但轮数较少
假设只看密码学设计，不管速度、不管硬件、不管使用方便，哪个像建造最厚的保险库？
Serpent-256
从“距离被分析突破还有多少轮”这个角度看，Serpent 的安全余量明显更保守。

Zcash 地址主要分为三类：
t1 和 t3 开头的地址属于透明地址，不具备隐私保护，交易金额、余额和交易记录都可以在区块链上公开查看；
z 开头的地址属于屏蔽地址，支持隐私交易，可以隐藏交易金额和交易双方信息，其中包括早期 Sprout 地址和后来的 Sapling 地址；
u 开头的地址属于 Unified Address（统一地址），是目前推荐的新型地址格式，可以包含 Orchard 最新隐私协议，适合现在的新用户使用。
简单来说：
t1、t3 = 不隐私；
z = 隐私；
u = 当前推荐的隐私地址。
可能未来有变化，不过当前是这样
