Project profile

Bitcoinは、個人間の決済とデジタルな価値の移転のための、オープンソースの分散型ネットワークです。サトシ・ナカモトが2008年のホワイトペーパーで構想を示し、ネットワークは2009年に稼働を開始しました。参加者は、銀行や中央の決済運営者に台帳管理を任せることなく価値を移転できます。ブロックチェーンは共有される公開の取引履歴を提供し、プロトコルは取引とブロックが受け入れられる条件を定めます。 BTCはこのネットワークのネイティブ資産で、支払い、送金、取引手数料に使われます。1 BTCは1億サトシに分割できます。ウォレットはBTCの受け取りや使用に必要な鍵と情報を管理し、コイン自体はネットワークの取引記録に表されます。他のブロックチェーンのラップドトークンは、独自の発行・保管の仕組みを通じてBTCを表す資産であり、Bitcoin上のネイティブBTCとは異なります。 Bitcoinはプルーフ・オブ・ワーク(PoW)を採用しています。マイナーは取引を候補ブロックにまとめ、必要な難易度を満たすブロックを作るために計算で競います。フルノードは合意ルールに従って取引とブロックを独立に検証し、マイナーが作ったデータでも無効なら拒否します。マイニングは取引の順序付けに寄与し、過去の履歴を変更するコストを高めますが、他の参加者が受け入れるべきルールをマイナーが単独で決めるわけではありません。 取引には未使用トランザクション出力、すなわちUTXOが使われます。取引は既存の出力を使用して新しい出力を作り、送信者に返すおつりも含めることができます。ノードは、入力がまだ使用されていないこと、使用条件が満たされていること、入力の金額で出力の金額を賄えることを確認します。通常、使用の承認にはデジタル署名が用いられます。有効なブロックに含まれた取引は、後続ブロックが積み重なるにつれて追加の承認を得ますが、ブロック間の時間は一定ではありません。 Bitcoinの合意ルールでは、総発行量の上限は2,100万BTCです。新しいBTCはブロック補助金を通じて流通し、補助金は発行が終わるまで210,000ブロックごとに半減します。マイナーは、新しく発行されるコインとは別に取引手数料も受け取れます。発行スケジュールは固定の暦日ではなくブロック高に従って進み、ネットワークにブロックが加わるにつれて、新たに発行されるBTCの量が段階的に減少します。 Bitcoinは店舗での支払い、国際送金、デジタル資産の直接保有に使われます。自己管理では保有者が取引の署名に使う鍵を管理し、カストディサービスでは提供者が保有者に代わって鍵を管理します。公開台帳ではアドレスを基にオンチェーンの送金を追えますが、アドレスだけで保有者の実際の身元が確定するわけではありません。

AnchorWatch obtains Nevada state charter qualification, providing Bitcoin custody services

BlockBeats news, on October 19, according to The Block, AnchorWatch Trust Company officially opened this Monday, becoming a qualified Bitcoin custody institution licensed in Nevada. The company revealed to the media that the Nevada Financial Institutions Division has officially authorized it to provide custody services. Its target clients mainly include trustees, listed companies, trust institutions, and high-net-worth individuals requiring qualified Bitcoin custody services. In terms of fee structure, AnchorWatch adopts a fixed USD rate based on vault size, rather than a percentage of the assets under custody, with a monthly custody fee capped at $10,000. This means that once a client's monthly fee reaches this cap, no additional custody costs will be incurred regardless of additional Bitcoin purchases or asset growth due to appreciation. Regarding key management and custody architecture, AnchorWatch offers institutional clients two different options. In its flagship model, AnchorWatch Trust Company holds the core keys required for qualified custody, while allowing clients, trustees, or executives to hold an additional key themselves. In another distributed custody model, key control is decentralized among multiple parties, jointly managed by AnchorWatch, BitGo located in the United States, and CoinCorner located on the Isle of Man, further reducing single point of failure risk.

Analyst: Bitcoin MVRV percentile drops below 30, still consistent with accumulation range characteristics

BlockBeats news, on October 18, crypto analyst Darkfost posted that after Bitcoin was resisted near $87,000, the MVRV percentile fell back below 30, entering the transitional phase after market capitulation again. He believes the current valuation still fits the characteristics of an accumulation range. Darkfost explained that MVRV is used to compare Bitcoin's market value with realized value, the latter calculated based on the price at the most recent on-chain movement of each BTC. His method does not simply observe the raw MVRV value but measures the current value's relative position in historical evolution to reduce the impact of Bitcoin's structural changes and market cycles on indicator interpretation, analyzing it within the current market environment. He pointed out that historically, Bitcoin has only been at this valuation level about 25% of the time. Although it has now left the extremely undervalued range that always coincided with market lows in the past, it still fits the characteristics of the historical accumulation range.
