ブロック【block】- ブロックチェーン開発 ・オフショア開発なら株式会社BAP
Sorry, this entry is only available in 日本語. ブロックチェーンシステムにおいて、一定量のトランザクションデータをまとめて永続的に記録するファイルを ブロック と呼びます。 ブロックチェーン開発 においてはブロックの設計によってトランザクションスピードに影響がでるため、重要な項目です。 時間とともに新たに生成されたトランザクションデータは、 1.トランザクションプールと呼ばれるデータ貯蔵庫に一時的に保管され、 2. マイニング作業によって新たなブロックとしてまとめあげられ、 3. 正当性が承認されると古いブロックに繋がれてチェーンを形成します。 ブロックがより長くブロックチェーンに埋め込まれるにつれて変更や削除がより困難になり、ブロックチェーンの不可逆的なトランザクション記録が形成されます。 ブロックが存在しないブロックチェーン IOTAやNANOのような、DAG型（有向非巡回グラフ型）と呼ばれるタイプのブロックチェーンは、トランザクションをブロックとして纏めずに関連のあるトランザクション同士をハッシュで繋いでいます。 ブロックがないので、ブロック生成時間や送信速度の遅延、承認報酬のために高い手数料を支払うといった問題を解消することができます。 その一方で、ブロックを形成することで得られてたセキュリティ面の課題が残っており、今後の発展が望まれています。 ブロックチェーン開発 のご相談は株式会社BAPへ 株式会社BAPでは ブロックやチェーンのデザインを含めた開発コンサルティングが可能です。 見積、相談、開発委託などのお問い合わせはこちらへ。...

VPN – 仮想プライベートネットワーク
Sorry, this entry is only available in 日本語. VPN【 Virtual Private Network】 仮想プライベートネットワーク VPN とは、通信事業者の公衆回線を経由して構築された仮想的な組織内ネットワークまたはそのようなネットワークを構築できる通信サービスを指します。 古くは電話回線で用いられていたいたもので、全国に拠点を持つ大企業の内線電話などを公衆網を中継して接続するサービスでした。 その後、VPNは一般的に企業内ネットワークの拠点間接続などに使われ、自社ネットワーク内部の通信と区別がつかないレベルで遠隔地の拠点との通信が行えるようになってきました。 VPNを用いることで、安全な通信ルートを確保した上で重要な情報をやり取りでき、悪意ある外部アクセス者から情報を守ることができるようになります。 活用例としては、空港や駅、商業施設などで使われている無料Wi-Fiサービス上での通信をVPNを用いて暗号化することで通信内容を盗み見られるリスクを避けることができます。 VPN の実装 以前は各拠点間に専用線を入れて直接通信していたケースが見られましたが、近年ではキャリアのバックボーンを利用することでコストを抑えた拠点間接続が可能です。 もちろんバックボーン内では多くの企業のデータが混在することになりますが、データは認証や暗号化によって保護されており、漏洩、盗聴などの危険性は低くなります。 バックボーンにインターネットを利用する「インターネットVPN」も作られており、通常のVPNサービスよりもさらにコストを抑えて利用が可能となっていますが、セキュリティや通信品質の確保はキャリアの通信網を利用するよりもやや難しくなっています。 ブロックチェーンが知られるようになってからは、VPNのブロックチェーン化プロジェクトも発足しています。 一例として、Mysteriumがあり、余分な帯域幅をネットワークに共有するユーザーへの報酬としてデジタル通貨を獲得できるように設計しています。...

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...
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。...
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。...
