Bitcoin Cash came about in 2017 and was created to address concerns over Bitcoin's scalability while staying as close to its original vision as a form of digital cash. It’s a hard fork of the Bitcoin blockchain, meaning the network “split” in two at a certain block as decided on by various miners and developers within the Bitcoin network. Bitcoin Cash uses an increased block size with an adjustable level of difficulty to ensure fast transactions as its user base scales. At a technical level, Bitcoin Cash works exactly the same as Bitcoin. Both platforms have a hard cap of 21 million assets, use nodes to validate transactions, and use a PoW consensus algorithm. However, BCH operates faster and has lower transaction fees than its predecessor, thanks to the aforementioned larger block size. Bitcoin Cash can support 25,000 transactions per block compared with Bitcoin’s 1,000 to 1,500 per block. Additionally, as of March 2022, the maximum block size for BCH was increased fourfold to 32 MB.

Bitcoin was created in 2009 by Satoshi Nakamoto, a pseudonymous developer. Bitcoin is designed to be completely decentralized and not controlled by any single authority. With a total supply of 21 million, its scarcity and decentralized nature make it almost impossible to inflate or manipulate. For this reason, many consider bitcoin to be the ultimate store of value or ‘Digital Gold’. Bitcoin is fully open-source and operates on a proof-of-work blockchain, a shared public ledger and history of transactions organized into "blocks" that are "chained" together to prevent tampering. This technology creates a permanent record of each transaction. Users on the Bitcoin network verify transactions through a process known as mining, which is designed to confirm new transactions are consistent with older transactions that have been confirmed in the past, ensuring users can not spend a Bitcoin they don’t have or attempt to double-spend coins.

Samourai Wallet is a privacy-focused Bitcoin wallet that offered Whirlpool coin mixing and Ricochet multi-hop transactions. The prosecution’s central allegations were not simply that “they wrote open-source code.” Prosecutors alleged that the two men developed, promoted, and operated the related services, collected fees, and knew the services were being used to move criminal proceeds. In April 2024, the two were arrested and charged. Prosecutors accused them of conspiring to commit money laundering and of operating an unlicensed money-transmitting business. In November 2025, Rodriguez was sentenced to five years in prison and Hill to four years. Each was also sentenced to three years of supervised release and fined $250,000. The two also agreed to forfeit approximately $237.8 million. The Justice Department’s sentencing announcement said that the forfeiture amount represented traceable criminal proceeds processed through Samourai, and that the two had paid approximately $6.367 million in fees collected by Samourai. What an evil law. This is nothing but the malicious persecution of Bitcoin developers.

I caught the early bus to the downtown office, where I spent the morning answering emails and polishing a project report. For lunch I stopped at the nearby market stall and ate a warm bowl of ramen with a side of pickled vegetables. After a quick walk back to the office, I joined a short video call, wrapped up the day's tasks, and headed home on the evening train, watching the city lights flicker past the windows.

ElectrumはWindows、macOS、Linux、Androidで動作する軽量デスクトップウォレットです。フルブロックチェーンをダウンロードせず、ブロックヘッダーのみを取得する簡易支払い検証（SPV）を使用しており、数分で同期できます。ユーザーはバイトあたりの手数料を手動で設定するか、低・中・高のプリセット手数料を選択して、確認速度とコストのバランスを調整できます。また、2‑of‑2や2‑of‑3などのマルチシグ機能を提供し、資金の安全性を向上させます。ウォレットは12語または24語のニーモニックフレーズを生成し、オフラインでバックアップでき、すべての秘密鍵はローカルで生成・保存されます。オープンソースコードはコミュニティによる監査が可能です。 Wasabi WalletはWindows、macOS、Linuxで利用できるプライバシー重視のデスクトップウォレットで、Bitcoin Coreのフルノード実装を基盤としています。その主要機能はWasabi CoinJoinで、同額のビットコインを定期的に混合し、チェーン上での追跡可能性を低減します。さらに、統合されたTorネットワークを通じてすべてのネットワークトラフィックをルーティングし、ユーザーのIPアドレスを隠蔽します。ウォレットはBIP‑39標準のニーモニックを使用してシードを生成し、秘密鍵はローカルで暗号化保存されます。コードは完全にオープンソースで、セキュリティ監査が可能です。フルノードウォレットであるため、ブロックチェーンデータはローカルに保存され、サードパーティサーバーへの依存がありません。高いプライバシー保護を必要とし、混合待機時間を受け入れられるユーザーに適しています。 Cake Walletは主にMonero（門羅コイン）向けに設計されたオープンソースの非カストディアルウォレットで、Bitcoin（ビットコイン）などの主要暗号資産もサポートしています。プライベートキーは端末内で生成・保存され、内蔵の手数料無料スワップ機能、Silent Payments、Payjoin、Tor接続、自カスタムノード設定などのプライバシー機能が備わっており、助詞フレーズで安全にバックアップできます Cake Wallet is an open‑source non‑custodial wallet primarily focused on Monero (XMR) while also supporting major assets such as Bitcoin (BTC).

Electrum is a lightweight desktop wallet that works on Windows, macOS, Linux, and Android. It uses Simplified Payment Verification (SPV) to download only block headers instead of the full blockchain, allowing synchronization within minutes. Users can manually set the fee per byte or choose low/medium/high preset fees to balance confirmation speed and cost, and it offers multi‑signature options such as 2‑of‑2 and 2‑of‑3 for added security. The wallet generates a 12‑ or 24‑word mnemonic that can be backed up offline; all private keys are generated and stored locally, and the software’s open‑source code can be audited by the community. Wasabi Wallet is a privacy‑focused desktop wallet available for Windows, macOS, and Linux, built on the Bitcoin Core full‑node implementation. Its core feature is Wasabi CoinJoin, which periodically mixes users’ coins of equal amounts to reduce on‑chain traceability, and all network traffic is routed through an integrated Tor network to hide the user’s IP address. The wallet uses a BIP‑39 standard mnemonic to generate a seed, encrypts private keys locally, and its code is completely open source for security auditing. Because it is a full‑node wallet, blockchain data is stored locally, eliminating reliance on third‑party servers; it is ideal for users who require strong privacy protection and are willing to tolerate the mixing waiting time.

The Shamir secret sharing scheme (1979) is a fundamental cryptographic primitive. Its idea is to split a secret value (e.g., a private key) into n shares such that any t shares can reconstruct the secret, while t – 1 shares reveal no information about it.

Taproot’s upgrade, enabled by BIP 340, introduced Schnorr signatures to Bitcoin. A key mathematical property of Schnorr is linearity: given valid signatures for public keys P₁ and P₂, you can add those signatures together to obtain a valid signature for the combined public key P₁ + P₂. This property makes key‑aggregation protocols possible. MuSig2 (BIP 327) is a two‑round interactive signing protocol for n‑of‑n key aggregation. All participants combine their individual public keys into a single aggregate public key, then jointly produce a 64‑byte Schnorr signature. On‑chain, the result is indistinguishable from a single‑signer Taproot spend: no script is revealed, no private keys are exposed, and the transaction cost is the same as a regular single‑key payment. MuSig2 solves the privacy and cost issues of script‑based multisignatures, but it has a crucial limitation: every one of the n participants must cooperate. If even a single signer cannot participate or does not respond, the group cannot produce a signature. It does not support threshold schemes; full participation is required.

Taproot のアップグレードは BIP 340 によってビットコインで Schnorr 署名を可能にしました。Schnorr の重要な数学的性質のひとつは線形性です。すなわち、公開鍵 P₁ と P₂ に対応する有効な署名があれば、これらを加算することで、合成公開鍵 P₁ + P₂ に対する有効な署名を得ることができます。この性質により、キー集約プロトコルが実現可能になります。 MuSig2（BIP 327）は、n‑of‑n キー集約を行う 2 ラウンドの対話型署名プロトコルです。すべての参加者はそれぞれの公開鍵を集約して 1 つの合成公開鍵を作り、共同で 64 バイトの Schnorr 署名を生成します。チェーン上では、この結果は単一署名者による Taproot の支払いと区別がつかず、スクリプトは公開されず、個々の秘密鍵も露出しません。取引コストは他の単一鍵支払いと同等です。 MuSig2 はスクリプトマルチシグのプライバシーとコストの問題を解決しますが、重要な制限があります。すべての n 名の参加者が協力しなければならず、たとえ 1 名でも参加できない、または応答しない場合、グループ全体で署名を生成することはできません。閾値方式はサポートされておらず、全員の参加が必須です。

Shamirの秘密分散（1979年）という基礎的な暗号学的プリミティブに基づいています。その仕組みは、秘密の値（たとえば秘密鍵）を n 個のシェアに分割し、任意の t 個のシェアがあれば秘密を復元できる一方、t−1 個のシェアからは秘密に関する情報を一切得られないようにするものです。

scarce assets.

When someone tries to buy all the world's supply of a scarce asset, the more they buy the higher the price goes. At some point, it gets too expensive for them to buy any more. It's great for the people who owned it beforehand because they get to sell it to the corner at crazy high prices. As the price keeps going up and up, some people keep holding out for yet higher prices and refuse to sell.
