Bitcoin privacy is not about “hiding transactions” 🔒 — it is about reducing the connection between real-world identities and on-chain activities 🌐. To improve privacy, there are several approaches: use non-custodial wallets 🛡️, avoid repeatedly using the same address over a long period of time 🔑, minimize address linkability when receiving and sending funds 🔗, and use privacy-focused wallets and technologies such as CoinJoin and similar solutions 🕵️‍♂️.

I used to never understand the purpose of commercial monopolies. Now, it seems to me that some restrictions are not solely about profit, but also about preventing certain extreme and unhealthy forces from expanding uncontrollably through open environments. Open source is a great concept, but excessive openness can also become a vulnerability that may be exploited.

Yes. Most Nostr clients let you block users. After blocking someone, their posts and interactions are usually hidden in your client. However, this only applies to your client, not the entire Nostr network. Other clients or relays may still display that user’s content. はい。ほとんどのNostrクライアントでは、ユーザーをブロックできます。ブロックすると、通常はそのユーザーの投稿や交流内容が自分のクライアント上で非表示になります。 ただし、これは自分のクライアント内だけで有効で、Nostrネットワーク全体に適用されるわけではありません。他のクライアントやリレーでは、そのユーザーのコンテンツが表示される場合があります。

Cake Wallet is an open-source, non-custodial, multi-currency cryptocurrency wallet developed by Cake Labs. It is available on Android, iOS, macOS, and Linux. Because it is non-custodial, users control their own private keys and are responsible for backing up and protecting their recovery seed. Cake Wallet supports several cryptocurrencies, including Monero (XMR), Bitcoin (BTC), Ethereum (ETH), Litecoin (LTC), Bitcoin Cash (BCH), Polygon (POL), Solana (SOL), Tron (TRX), Nano (XNO), Zano (ZANO), and Decred (DCR). The exact assets and features may vary depending on the version and platform. <citation src="3"></citation> The wallet provides features such as sending and receiving cryptocurrency, built-in cryptocurrency swaps, purchasing and selling selected cryptocurrencies, multiple wallets and accounts, custom node selection, QR-code payments, hardware-wallet support, and backup and restore functions. <citation src="1,3,4"></citation> Cake Wallet has a strong focus on privacy, especially through its Monero support. It also provides Bitcoin privacy features such as Silent Payments and PayJoin, Litecoin MWEB support, and Tor integration. However, using a privacy-focused wallet does not automatically make every transaction completely anonymous; privacy depends on the cryptocurrency, settings, network connection, and the way the wallet is used. Cake Wallet is suitable for users who want a mobile-friendly, self-custodial wallet with support for Monero, Bitcoin, and other cryptocurrencies. It is not a hardware wallet by itself, although it can work with supported hardware wallets. Users should download it only from the official website or verified app stores, and should never share their recovery seed or private keys. Cake Walletは、Cake Labsが開発するオープンソースの非カストディアル型マルチ通貨暗号資産ウォレットです。Android、iOS、macOS、Linuxに対応しています。非カストディアル型であるため、秘密鍵はユーザー自身が管理し、リカバリーシードのバックアップと保護についてもユーザー自身が責任を負います。 Cake Walletは、Monero（XMR）、Bitcoin（BTC）、Ethereum（ETH）、Litecoin（LTC）、Bitcoin Cash（BCH）、Polygon（POL）、Solana（SOL）、Tron（TRX）、Nano（XNO）、Zano（ZANO）、Decred（DCR）など、複数の暗号資産に対応しています。対応する資産や機能は、アプリのバージョンや利用するプラットフォームによって異なる場合があります。 主な機能には、暗号資産の送受信、ウォレット内での交換、対応する暗号資産の購入と売却、複数のウォレットやアカウントの管理、カスタムノードの選択、QRコードによる支払い、ハードウェアウォレットとの連携、バックアップと復元などがあります。 Cake Walletは、特にMoneroへの対応を中心に、プライバシーを重視しています。また、BitcoinのSilent PaymentsやPayJoin、LitecoinのMWEB、Tor接続にも対応しています。ただし、プライバシー重視のウォレットを使用しただけで、すべての取引が完全に匿名になるわけではありません。実際のプライバシー保護のレベルは、使用する暗号資産、設定、ネットワーク接続、ウォレットの使い方によって異なります。 Cake Walletは、Monero、Bitcoin、その他の暗号資産を、使いやすいモバイル中心の自己管理型ウォレットで管理したいユーザーに適しています。Cake Wallet自体はハードウェアウォレットではありませんが、対応するハードウェアウォレットと連携できます。アプリは公式サイトまたは確認済みのアプリストアからダウンロードし、リカバリーシードや秘密鍵は絶対に他人に教えないでください。

Electrum: Classic, lightweight, fast, and feature-rich. It is suitable for everyday use and advanced users, but privacy protection is not its main focus. Wasabi: Focused on privacy. It supports CoinJoin mixing, which can improve transaction privacy, but it is relatively complex to use and is more suitable for users who have specific privacy needs. Sparrow Wallet: Feature-rich, with a strong focus on privacy and user control. It supports hardware wallets, PSBT, and various node connection methods, and it can also be used with CoinJoin. It is generally considered more modern than Electrum and more flexible than Wasabi.

24単語のランダムな助記符（ニーモニック）を解読することの真の難しさは、その天文学的な組み合わせ数にあります。2,048単語のワードリストに基づくと、基礎となるエントロピーは256ビットであり、攻撃者は2の256乗通りという、約1.15 × 10の77乗という膨大な組み合わせに直面することになります。たとえ毎秒10京回の試行が可能なスーパーコンピュータが存在したとしても、全ての可能性を網羅するのにかかる時間は約3.6 × 10の54乗年となり、現在の宇宙の年齢である138億年を遥かに上回ります。 Open Electrum, select View → Show Console, and enter: make_seed(nbits=256, language="english", seed_type="segwit")

The true difficulty of cracking a 24-word random mnemonic seed lies in its astronomical number of possible combinations. Based on a wordlist of 2,048 words, the underlying entropy is 256 bits, meaning an attacker faces 2 to the power of 256 possible combinations—a value approximately equal to 1.15 times 10 to the 77th power. Even assuming the existence of a supercomputer capable of making 100 quadrillion attempts per second, the time required to traverse all possibilities would be roughly 3.6 times 10 to the 54th power years, while the current age of the universe is only 13.8 billion years.

seed = make_seed(nbits=256, language="english", seed_type="segwit") print(seed) from electrum.mnemonic import calc_seed_type calc_seed_type(seed) Expected result: 'segwit'

Electrum: Generate a 24-Word Native SegWit Seed from the Console Open Electrum, select View → Show Console, and enter: make_seed(nbits=256, language="english", seed_type="segwit") This generates a 24-word Electrum seed for a native SegWit wallet. Write the words down in the correct order and store them offline. Never share the seed, upload it to a website, save it in cloud storage, or store it in an unencrypted file.

Whenever personal information is leaked, they simply blame hackers or cyberattackers. It’s completely absurd. The real root of the problem is their heavy-handed push for an extreme real-name identification system.

- Pinch of salt – a tiny handful taken between thumb and forefinger. - Clove of garlic – one individual segment of a garlic head; the usual “single garlic piece.” - Dash of sugar – a quick shake from the container, a little less than a pinch. - Knob of butter – a small, rounded piece you can scoop with a knife or spoon. - Splash of milk – a brief pour, just enough to add a hint of moisture or flavor. How to use them: replace the generic word “little” with the ingredient‑specific term when writing or speaking recipes. The pattern is always “[quantity word] of [ingredient],” matching how native speakers normally measure each item. For example: “Add a pinch of salt,” “Stir in a dash of sugar,” “Melt a knob of butter.”

Coldcard 事件集中爆发于 2026年7月30日前后，但漏洞实际上早在 2021年3月 的固件更新中就已被引入：部分设备在生成钱包助记词时没有正确使用硬件随机数，而是采用了可被推测的软件随机数据，使攻击者能够计算出私钥并转走比特币。7月底，多批 Coldcard 钱包遭到集中清空；截至8月初，公开统计的损失已接近 1,367枚比特币、约8,900万美元。 漏洞源于Coldcard在 2021年3月17日 发布的4.0.0固件所引入的随机数生成错误，使部分设备生成的助记词随机性严重不足，攻击者可能离线推算私钥； 约500个单签钱包在25分钟内被转走约594枚比特币；Galaxy Research 后续采用更宽的地址聚类口径，估计首轮攻击在41分钟内涉及1,196个地址、约1,082.65枚比特币，截至8月1日三轮可疑盗转合计约1,367枚比特币。
