-    Unlike other messaging platforms, SimpleX has <strong>no identifiers assigned to the users</strong>. It does not rely on phone numbers, domain-based addresses (like email or XMPP), usernames, public keys or even random numbers to identify its users — we don't know how many people use our SimpleX servers.
+    他のメッセージング プラットフォームとは異なり、SimpleX には<strong>ユーザーに割り当てられる識別子がありません</strong>。 ユーザーを識別するために、電話番号、ドメインベースのアドレス (電子メールや XMPP など)、ユーザー名、公開キー、さらには乱数にも依存しません。 —我々もSimpleX サーバーを何人が使用しているかはわかりません。
 </p>
 <p>
-    To deliver messages SimpleX uses <a href="https://csrc.nist.gov/glossary/term/Pairwise_Pseudonymous_Identifier">pairwise anonymous addresses</a> of unidirectional message queues, separate for received and sent messages, usually via different servers. Using SimpleX is like having <strong>a different “burner” email or phone for each contact</strong>, and no hassle to manage them.
+    メッセージを配信するために、SimpleX は一方向メッセージ キューの<a href="https://csrc.nist.gov/glossary/term/Pairwise_Pseudonymous_Identifier">ペアワイズ匿名アドレス</a>を使用し、受信メッセージと送信メッセージに分けて、通常は異なるサーバーを経由します。 SimpleX を使用することは、<strong>別の「バーナー」 を使用するようなものです。 連絡先ごとにメールまたは電話</strong>を使用できるため、管理に手間がかかりません。
 </p>
 <p>
-    This design protects the privacy of who you are communicating with, hiding it from SimpleX platform servers and from any observers. To hide your IP address from the servers, you can <strong>connect to SimpleX servers via Tor</strong>.
+    この設計により、通信相手のプライバシーが保護され、SimpleX プラットフォーム サーバーや監視者からプライバシーが隠されます。 IP アドレスをサーバーから隠すには、<strong>Tor 経由で SimpleX サーバーに接続</strong>します。

-    <a href="https://en.wikipedia.org/wiki/Peer-to-peer">P2P</a> messaging protocols and apps have various problems that make them less reliable than SimpleX, more complex to analyse, and vulnerable to several types of attack.
+    <a href="https://en.wikipedia.org/wiki/Peer-to-peer">P2P</a> メッセージング プロトコルとアプリには、SimpleX よりも信頼性が低く、分析がより複雑になるさまざまな問題があり、 いくつかの種類の攻撃に対して脆弱です。
 </p>
 <ol style="list-style: auto; padding-left: 1em;">
     <li>
-        P2P networks rely on some variant of <a href="https://en.wikipedia.org/wiki/Distributed_hash_table">DHT</a> to route messages. DHT designs have to balance delivery guarantee and latency. SimpleX has both better delivery guarantee and lower latency than P2P, because the message can be redundantly passed via several servers in parallel, using the servers chosen by the recipient. In P2P networks the message is passed through <em>O(log N)</em> nodes sequentially, using nodes chosen by the algorithm.
+        P2P ネットワークは、メッセージをルーティングするために <a href="https://en.wikipedia.org/wiki/Distributed_hash_table">DHT</a> の一部の変種に依存します。 DHT の設計では、配信保証と遅延のバランスを取る必要があります。 SimpleX は、受信者が選択したサーバーを使用して、メッセージを複数のサーバーを介して並行して冗長的に渡すことができるため、P2P よりも優れた配信保証と低い遅延の両方を備えています。 P2P ネットワークでは、メッセージはアルゴリズムによって選択されたノードを使用して、<em>O(log N)</em> 個のノードを順番に通過します。
     </li>
     <li>
-        SimpleX design, unlike most P2P networks, has no global user identifiers of any kind, even temporary, and only uses temporary pairwise identifiers, providing better anonymity and metadata protection.
+        SimpleX 設計は、ほとんどの P2P ネットワークとは異なり、一時的であってもいかなる種類のグローバル ユーザー識別子も持たず、一時的なペアごとの識別子のみを使用するため、より優れた匿名性とメタデータ保護が提供されます。
     </li>
     <li>
-        P2P does not solve <a href="https://en.wikipedia.org/wiki/Man-in-the-middle_attack">MITM attack</a> problem, and most existing implementations do not use out-of-band messages for the initial key exchange. SimpleX uses out-of-band messages or, in some cases, pre-existing secure and trusted connections for the initial key exchange.
+        P2P は <a href="https://en.wikipedia.org/wiki/Man-in-the-middle_ Attack">MITM 攻撃</a> 問題を解決せず、既存の実装のほとんどは最初の鍵交換に帯域外メッセージを使用していません 。 SimpleX は、最初のキー交換に帯域外メッセージを使用するか、場合によっては既存の安全で信頼できる接続を使用します。
     </li>
     <li>
-        P2P implementations can be blocked by some Internet providers (like <a href="https://en.wikipedia.org/wiki/BitTorrent">BitTorrent</a>). SimpleX is transport agnostic - it can work over standard web protocols, e.g. WebSockets.
+        P2P の実装は、一部のインターネット プロバイダー (<a href="https://en.wikipedia.org/wiki/BitTorrent">BitTorrent</a> など) によってブロックされる場合があります。 SimpleX はトランスポートに依存しません- WebSocketのような標準的な Web プロトコル上で動作します。
     </li>
     <li>
-        All known P2P networks may be vulnerable to <a href="https://en.wikipedia.org/wiki/Sybil_attack">Sybil attack</a>, because each node is discoverable, and the network operates as a whole. Known measures to mitigate it require either a centralized component or expensive <a href="https://en.wikipedia.org/wiki/Proof_of_work">proof of work</a>. SimpleX network has no server discoverability, it is fragmented and operates as multiple isolated sub-networks, making network-wide attacks impossible.
+        すべての既知の P2P ネットワークは、各ノードが検出可能であり、ネットワーク全体が動作するため、<a href="https://en.wikipedia.org/wiki/Sybil_question">Sybil 攻撃</a>に対して脆弱である可能性があります。 この問題を軽減する既知の対策には、一元化されたコンポーネントか、高価な<a href="https://en.wikipedia.org/wiki/Proof_of_work">作業証明</a>が必要です。 SimpleX ネットワークにはサーバーの検出機能がなく、断片化されており、複数の分離されたサブネットワークとして動作するため、ネットワーク全体への攻撃は不可能です。
     </li>
     <li>
-        P2P networks may be vulnerable to <a href="https://www.usenix.org/conference/woot15/workshop-program/presentation/p2p-file-sharing-hell-exploiting-bittorrent">DRDoS attack</a>, when the clients can rebroadcast and amplify traffic, resulting in network-wide denial of service. SimpleX clients only relay traffic from known connection and cannot be used by an attacker to amplify the traffic in the whole network.
+        P2P ネットワークは、<a href="https://www.usenix.org/conference/woot15/workshop-program/presentation/p2p-file-sharing-hell-exploiting-bittorrent">DRDoS 攻撃</a>に対して脆弱になる可能性があります。 クライアントがトラフィックを再ブロードキャストして増幅する可能性があり、その結果、ネットワーク全体のサービス拒否が発生する可能性があります。 SimpleX クライアントは既知の接続からのトラフィックのみを中継するため、攻撃者がネットワーク全体のトラフィックを増幅するために使用することはできません。

Unlike client-server architecture, all peers in a P2P network both provide and consume the resources. In the context of messaging, P2P architecture usually means that the messages are sent between peers, without user accounts or messages being stored on any servers. Examples are Tox, Briar, Cwtch and many others.</p><p>The advantage is that the participants do not depend on any servers. There are <a href="./SIMPLEX.md#comparison-with-p2p9-messaging-protocols">multiple downsides</a> to that architecture, such as no asynchronous message delivery, the need for network-wide peer addresses, possibility of network-wide attacks, that are usually mitigated only by using a centralized authority.

Unlike client-server architecture, all peers in a P2P network both provide and consume the resources. In the context of messaging, P2P architecture usually means that the messages are sent between peers, without user accounts or messages being stored on any servers. Examples are Tox, Briar, Cwtch and many others.</p><p>The advantage is that the participants do not depend on any servers. There are <a href="./SIMPLEX.md#comparison-with-p2p9-messaging-protocols">multiple downsides</a> to that architecture, such as no asynchronous message delivery, the need for network-wide peer addresses, possibility of network-wide attacks, that are usually mitigated only by using a centralized authority.
