0ｘ 【DEX プロトコル】
Sorry, this entry is only available in 日本語. 0x (https://0xproject.com/) は異なるトークン同士を取引する分散型取引所(DEX)を構築するためのプロトコルで、イーサリアムネットワーク上に構築されています。 一般的なDEXでは、取引注文（オーダーブック）や注文キャンセルなどの全てのトランザクションをブロックチェーン上で処理します。 ブロックチェーンの承認作業には時間とコストがかかりますから、取引時にかかる時間と手数料が多くなってしまいます。 更に、イーサリアムネットワーク全体にも負荷がかかり、DEX以外でのトランザクションを阻害する可能性があります。 0xでは、互いにトークンの取引を行う処理だけをブロックチェーン上で行い、それ以外の取引注文などはオフチェーンで行うようにすることで効率的な取引と低い手数料を可能にします。 0xの仕組み このように0x プロトコル上では、取引の決済のみがイーサリアムブロックチェーン上で行われ、それ以外の取引の注文などはオフチェーンで処理されます。 左側の図で、2から4までがオフチェーンで行われ、7でのみオンチェーンの決済が行われます。 メイカー:...

Sorry, this entry is only available in 日本語. 1. オフショアに関する意識調査結果から 少し古くなりますが、IPAの調査データに次のようなものがあります。IPA (Information technology Promotion Agency) がオフショアに関してIT企業に出したアンケートの結果です。調査Aでは、70％以上が「現在より拡大したい」と言っており、調査Bでは、「70％以上が予定なし」と答えています。 まったく相反するような結果が出ていますが、実はこれ、調査Aは既にオフショアを実施している企業からの回答であり、調査Bは過去に一度もオフショアを実施したことがない企業からの回答なのです。 一概には言えませんが、オフショアで開発を経験した企業はそのメリットを享受し、さらに利益を求めて拡大へと向かい、経験したことがない企業は、実感としてメリットを捉えることができないためにさらにオフショア実施に対して消極的になってしまっているという構図がうかがえます。 2....

タイムスタンプ 【Timestamp】
Sorry, this entry is only available in 日本語. タイムスタンプ （timestamp）はあるイベントが記録された日時・日付・時刻などを記録し、記録が存在していることと改竄されていないことを証明するシステムを指します。 電子署名などで用いられているRFC3161 Time stamp protocolではPKIを利用しており、時刻認証局(TSA:Time-Stamping Authority)がハッシュ値に時刻情報を偽造できないようにして結合したタイムスタンプ(正確にはタイムスタンプトークンと呼びます)を利用者に送付しています。 記録を僅かでも更新した場合、変化したハッシュ値のみがTSAに提示されるので利用者は記録内容を知られずにタイムスタンプを取得できます。 タイムスタンプでの管理が必要なデータは通常、一貫性のある書式で記録されているので異なる記録の比較を簡単に行うことができます。 加えて、時間の経過に伴って変化するイベントの進行状況の追跡が可能となります。 タイムスタンプは一般にイベントの記録作成や時系列（”sequence of events”, SOE）の評価を行うために使用されます。 どちらのケースでも、タイムスタンプはイベント記録を認識するタグのように使われます。 ビットコインのブロックチェーンの例では、各トランザクションやブロックの生成時刻が電子署名と同様の方法でタイムスタンプを用いて管理されています。 多くのOSのファイルシステムではファイルの作成日時（UNIXやUnix系OSではctimeと呼ばれます）、更新日時（mtime）、アクセス日時（atime）がタイムスタンプとして記録されます。 UNIXにおけるstatなどではこれらのデータがシステムコールで取り出すことができます。 タイムスタンプ システムの課題 仮に一貫性のある記録をタイムスタンプとともに作成しても、後から改竄されてしまうと信頼性がなくなってしまいます。 特に、不特定多数からのアクセスが可能な記録は容易に改竄できてしまうため、タイムスタンプを含むデータログの保管システムやサーバには高度なセキュリティが施す必要があります。 タイムスタンプ の例（Wikipediaより引用） 2005-10-30 T 10:45 UTC 2007-11-09 T 11:20 UTC Sat Jul 23 02:16:57 2005...

Sorry, this entry is only available in 日本語. マイニング は、1.新たなトランザクションのデータをトランザクションプール中から抽出し、2. ハッシュIDを元にいくつかのトランザクションをまとめて新たなブロックを形成し、3. １つ前のブロックに追加するプロセスです。ビットコインやイーサリアムの成功はマイニング報酬による運営者の動機付けに依存しているので、 パブリック型の ブロックチェーン開発 を考える上で、マイニングの設計は重要な意味を持ちます。 ビットコインの場合、このブロック形成のための作業をネットワーク内のマイニング用ノード同士で競争を行い、最も早く追加したマイニング用ノードに対してビットコインが報酬として付与されるようになっています。( PoW ) ビットコインの送信者は、ウォレット内で送金時の手数料を設定できるようになっています。 トランザクションごとに手数料にばらつきが存在するので、マイニングを行う人（マイナー）は手数料の大きいトランザクションばかりをブロックにする傾向があります。 送金時の手数料が高いほど送金が早く済むのはこのためです。 ブロックチェーン開発 は株式会社BAPへ 株式会社BAPは500台のマイニングマシン設定および運営を行った実績があり、 ブロックチェーン開発を手がけています。(詳しくはこちらへ。） 新たなロジックを含むブロックチェーンに関する相談はいつでも受け付けております。 お問い合わせはこちらへ。...
ブロックチェーンの不正を防ぐ3つの暗号技術
Sorry, this entry is only available in 日本語. 前回の記事で ブロックチェーン はネットワークにいる全員で台帳を共有していると言いましたね。 参考：中学生でもわかる！ブロックチェーンの仕組み それでは「悪い人が誰かの台帳にアクセスして書き換えることができるのでは？」と疑問に思う方もいるでしょう。もちろん ブロックチェーン にはデータの不正利用を防ぐ仕組みがあります。今回は不正を防ぐための３つの暗号技術について初心者にも分かりやすく説明します。 １．特定の人にしか見られないようにする暗号技術：公開鍵暗号化方式 ブロックチェーン に用いられる１つ目の暗号技術は公開鍵暗号化方式です。この技術によって、データを盗み見られたり、書き換えられたりすることを防いでいます。鍵による暗号化は共通鍵と公開鍵があります。 ブロックチェーン に用いられている公開鍵暗号化方式をより理解するために、まずは従来の方式である共通鍵暗号化について説明します。 共通鍵暗号化方式は二人が共通の鍵を持っていて、データを暗号化、復号化する方法です。これは、データを送りたい相手に事前に共通鍵を渡しておく必要があるのですが、どうやって共通鍵を渡すかが難しい点です。 情報が漏洩しやすいインターネット上で共通鍵を渡すことは危険であるため、厳重に管理されたルートで相手に渡す必要があります。また、第三者に共通鍵が流出した場合、簡単にデータを開封されてしまいます。このような鍵配送問題を解決したのが公開鍵暗号化方式です。 公開鍵暗号化方式の最大の特徴は暗号化するための鍵と復号化するための鍵が異なるということです。受信者はあらかじめ暗号化用の鍵を送信者に渡しておきます（相手に渡すため公開鍵と言われています）。 そして、暗号化された情報を復号化するための鍵は自分だけが持っておきます（自分だけが持っておくので秘密鍵と言われています）。 そして、送信者は事前に渡された公開鍵でデータを暗号化しておくります。この場合、もしデータが盗まれたとしても秘密鍵がなければ第三者は暗号文を読みとくことができません。 このデータを読むことが出来るのは秘密鍵を持っている受信者のみです。公開鍵暗号化方式は共通鍵暗号化方式の鍵配送問題を解決した暗号方式であり、情報漏洩を防ぐことができます。 しかし、注意すべき点は秘密鍵の管理です。秘密鍵が流出すると情報を盗まれる可能性があるため、秘密鍵の管理は慎重に行う必要があります。 ２．本人を証明するためのしくみ：電子署名 ブロックチェーンに用いられる２つ目の暗号技術は電子署名です。これは紙の文書におけるサインの役割を果たすもので、ネット上のなりすまし対策のために作られました。 電子署名は上記で説明した秘密鍵と公開鍵を利用していますが、注意すべき点は、電子署名と公開鍵暗号方式では鍵の役割が違うことです。 ＜公開鍵暗号方式＞ 秘密鍵：暗号文を復号化する。開鍵：平文を暗号化する ＜電子署名＞ 秘密鍵：平文に署名をする 公開鍵：署名が正しいか検証する では、電子署名は具体的にどのようにして行われるのでしょうか？メールを例にして説明します。 まず、一郎さんはまい子さんにメールを送るとき、通常のメッセージ（平文）と同時に、秘密鍵によって暗号化したメッセージ（暗号文）も同時に送ります。この過程で、送信するデータを秘密鍵を用いて暗号化することを電子署名といいます。 暗号化されたメッセージを受け取ったまい子さんは、誰の公開鍵で読めるか試してみます。すると、太郎さんの公開鍵で暗号文を読むことができました。さらに、解いた暗号文と平文を比べると一致していました。 こうして、確かに一郎さん本人からのメールだということが分かりました。このように、電子署名を用いると本人が送ったことを証明することができます。 ３．データを瞬時に照合できるしくみ：ハッシュ関数 ブロックチェーンに用いられる３つ目の暗号技術はハッシュ関数です。ハッシュ関数とは、どんな値を入力しても２５６ビットの長さの文字列が出てくる関数のことです。 どんなに長いまたは短い文字列を入力しても、一定の長さのハッシュ値が出てきます。また、入力値が一文字違うだけで、全く異なる文字列がでてきます。 ハッシュ関数の重要な特徴は一方向性です。データをハッシュ化するのは簡単ですが、ハッシュ化された結果から元のデータを推測することは不可能となっています。では、ハッシュ関数はどのように活用されているのでしょうか？ 例えば、オンラインで音楽ファイルなどのデータをダウンロードするときにハッシュ関数が役に立ちます。ダウンロード中にデータが破損する可能性がありますが、ダウンロード後に膨大なデータを隅々までチェックして破損しているかどうか調べるのは大変な作業です。 その際、ダウンロードしたデータのハッシュ値と、ダウンロード元のサイトに載っているハッシュ値を比較します。比較した結果、２つのハッシュ値が一致していれば、正常にダウンロードされたことが確認できます。...

ダナンのIT産業が急成長した理由と今後の課題
Sorry, this entry is only available in 日本語. １． ダナンのIT産業が急成長した理由 ますます発展するベトナムのIT業界の中で、ダナンは特に注目を集めています。ひと昔前、日本企業によるダナンへの投資は、製造・加工業が中心でした。 しかし、10年程前からソフト開発や設計などのIT分野への投資が目立つようになり、2018年には投資件数の25％がIT分野という状況になりました。 このようにダナンのIT産業が注目を浴びるようになった理由は何でしょうか？理由は３つあります。 １-１．人件費が安い ダナンのIT産業が急成長した大きな理由は人件費の安さです。ベトナムはASEAN諸国の中でも人件費が安い国です。ダナンはホーチミン、ハノイに次ぐ第3の都市ですが、その人件費は20％以上も安いと言われています。 賃金（月額） ハノイ ホーチミン ダナン 法定最低賃金 156 156 138 ワーカー（一般工職） 181 193 158 エンジニア（中堅技術者） 346 349 226 単位USD/月（JETRO 2016） さらに、ダナンのIT業界の離職率はわずか8％であり、ハノイやホーチミンが20％であるのに比べて非常に低くなっています。 このように、人件費が安く離職率が低いダナンのIT産業はオフショア開発先として注目を集め、多くの日本企業がダナンへ進出しました。 １-２．国による優遇政策 2010年、ダナンはベトナム政府からIT特区に認定されました。海外のIT企業に対する優遇政策として、法人税免除、土地リース料免除などが適用されました。 このように、国をあげて企業誘致に力を入れたことにより、多くの日本IT企業がダナンへ進出しました。 １-３．若く優秀な人材 若く優秀な人材が多いことも、ダナンのIT産業の成長に貢献しているでしょう。ダナン市には大学と短大が25校あります。その中で、工科大学、IT教育大学、IT短大などITを専攻とする学部・学科があります。 また、IT分野だけではなく、オフショア開発に重要な日本語教育も充実しています。さらに、ベトナムではほとんどの大学でインターンシップが必須となっています。 インターン先でIT企業を志望する学生も多いため、企業にとっては一緒に働いた経験のある学生を雇うことができるというメリットがあります。このように、ダナンはITと言語の両方で、若く優秀な人材が多いと言えるでしょう。 2． ダナンのIT産業...

What is Lean Startup? Success stories
Sorry, this entry is only available in 日本語 and Tiếng Việt. リーンスタート（lean start）とは、起業や新規事業などの立ち上げ（スタートアップ）が効率的に成功するためのマネジメント手法を指す言葉です。新規事業の立ち上げ時は人員や資金などのリソースが限られており、事業を安定して運営できるようになるまで非常にシビアなマネジメントが必要になります。システム開発に関しても同様で、開発費用や開発方法など、スタートアップの事業形態に即した方法を考える必要があります。この記事では、オフショア企業でのラボ型開発を活用することで、スタートアップが得られる大きなメリットについて知ることができます。 1. リーンスタートとは リーンスタートとは、アメリカの起業家エリック・リース氏が2008年に提唱した、起業や新規事業などの立ち上げ（スタートアップ）のためのマネジメント手法のことです。 リーンスタートは、事業家の思い込みで顧客にとって無価値な製品やサービスを開発してしまうことに伴う、時間、労力、資源、情熱のムダをなくすための方法論であり、最低限のコストと短いサイクルで仮説の構築と検証を繰り返しながら、市場やユーザーのニーズを探り当てていくのが特徴です。 2. 有名なリーンスタート成功事例 リーンスタートの成功事例として、代表的なものを２つ挙げます。 2.1．Instagram リーンスタートアップ事例中で最も有名なのが、Instagramです。 2010年10月6日にアップルのApp Storeに登場して以来、凄まじいスピードで多くのユーザーを虜にし、2020年3月現在、世界のインスタユーザーは10億人超えています。 日本でも2014年2月に日本語アカウントが開設され、月間アクティブユーザー数は、2015年6月に810万人、2016年3月に1200万人、同年12月に1600万人、2017年10月に2000万人を記録と、「インスタ映え」という言葉が流行語になるほど、その人気は凄まじいものです Instagramですが、もともとは「Burbn」という位置情報アプリとしてスタートしました。 しかし、一度リリースしたものの、思った以上に人気が出なかったことから、アイディアの構築・計測・学習を繰り返し、「写真の共有機能が最も人気」ということを見つけ出しました。 その結果、Burbnは写真投稿をメインにしたSNSに方向転換し、写真投稿・コメント・いいねの3機能を含んだ「Instagram」というサービスに昇華させました。 その後も、仮説検証を進め、アイディアの構築・計測・学習を進めていき、写真のエフェクトやストーリー、ショッピングなど、さまざまな機能の追加を行い、現在も変化を遂げています。 2.2．食べログ カカクコムグループが運営するグルメサイト「食べログ」は、日本企業におけるリーンスタートの代表的事例と言われています。2005年3月からサービスを開始し、レストランのユーザーによる5段階評価が掲載されるサイトを構築しました。 当初はグルメ本の情報をもとにした手打ちのデータベースで、担当者曰く、考えているものの30%しか実現に至らなかったとのことです。はじめはユーザー数が数十人程度だった食べログも、ユーザーの改善要望に可能な限り対応し、現在のシステムへ改善していきました。 その結果、現在は月間PV数が20億以上、月間利用者数は1億5万人以上となっています。リーンスタートの実践をきっかけに、右肩上がりの売上を誇るサービスに成長しています。 3. BAPの成功事例 3.1 ．動画編集・投稿型SNS『ジモフル』ー株式会社ジモフル様ご提供サービス https://jimoful.com/ ユーザーがカメラで撮影した動画や写真をアップロードし、システム上で動画作成・編集・投稿が可能です。他ユーザーからの動画の評価に応じて換金可能なアイテムを取得できます。 3.2．LIVE配信アプリ 『LIVE DREAMER』ーDreamer株式会社様ご提供サービス https://live-dreamer.com/ 誰でもアーティストやパフォーマーになって、動画やLIVEの配信が可能なアプリです。リスナーはLIVE配信中に課金アイテムを用いて投げ銭をすることができます。...

オフショアを始める前にやっておきたいこと
Sorry, this entry is only available in 日本語. 1. オフショアに関する意識調査結果から 少し古くなりますが、IPAの調査データに次のようなものがあります。IPA (Information technology Promotion Agency) がオフショアに関してIT企業に出したアンケートの結果です。調査Aでは、70％以上が「現在より拡大したい」と言っており、調査Bでは、「70％以上が予定なし」と答えています。 まったく相反するような結果が出ていますが、実はこれ、調査Aは既にオフショアを実施している企業からの回答であり、調査Bは過去に一度もオフショアを実施したことがない企業からの回答なのです。 一概には言えませんが、オフショアで開発を経験した企業はそのメリットを享受し、さらに利益を求めて拡大へと向かい、経験したことがない企業は、実感としてメリットを捉えることができないためにさらにオフショア実施に対して消極的になってしまっているという構図がうかがえます。 2. オフショアを始める前に何をする必要があるか？ このように経験したことがない企業が、オフショアを検討し始める際には当然のごとく不安が付きまとうことになります。また、何も考えずにオフショアを始めたのでは、過去の失敗事例同様の結末になりかねません。オフショアでの開発は、少なからずリスクが存在します。ここでは、リスクに対する不安を少しでも和らげるために、何をすれば良いかについて紹介します。オフショアを始める前には、最低でも次のことはやっておきましょう。 目的を明確にする 概要を理解する オフショアの事例を研究する オフショア先（国）候補を決める 2.1 目的を明確にする まず、オフショアの目的を明確にしておきましょう。目的により、オフショアの進め方、オフショア先が違ってきます。目的としては次のようなものが考えられます。 コスト削減 人件費の低い国での労働力を活用し、開発予算を抑えます 人材不足解消 日本国内での人材不足解消の手段を海外に求めます スキル導入 自社に技術スキルがなく、即時にそのスキルを導入したい場合に活用します 2.2 概要を理解する 次に、オフショアの契約形態とそのフォーメーションについて理解しておきましょう。大きく分けると受託開発型とラボ型の二つに分類することができます。 受託開発型 オフショア側に納品責任が有る、日本で一般的に採用されているものと同様の契約モデルです。事前に決められた仕様、期間、金額通りにシステムを納品することでプロジェクトが完了します。現地とブリッジSEを窓口にして開発を進めます。 ラボ型開発 同ーのオフショアチームを一定期間、一定予算で抱え込んで開発を進めるやり方です。お客様は、ブリッジSEを通して、或いは直接オフショア側のチームに指示を与えます。 3. オフショアの事例を研究する 目的がはっきりして、オフショアの概要を理解したら、次に他部門・他社のいろいろな事例について研究するとよいでしょう。先達が残してくれた事例は、失敗しないための貴重な財産になります。事例については、インターネットを検索しても、すぐにたくさんの成功事例、失敗事例を見つけることができます。その事例から、注意点やリスクを自分で読み取ることはとても役に立つでしょう。...
