id="bluesky">bluesky</h3> <p><a href="https://bsky.app" target="_blank">bluesky</a>はprotocol(プロトコル)に<a href="https://github.com/bluesky-social/atproto" target="_blank">at</a>を採用したsnsです。</p> <p><code>at</code>は以降、<code>atproto</code>とします。</p> <p>blueskyは現在、<a href="https://bsky.app/profile/did:plc:oc6vwdlmk2kqyida5i74d3p5/follows" target="_blank">bsky.team</a>が開発、運用している<code>atproto</code>のモデルサービスという位置づけです。</p> <p>bsky.teamの目標は、様々なサービスの裏で<code>atproto</code>が採用され、サービス間で意思疎通を図れるようにすることです。</p> <p>今までのサービスはそのサービス内でしかアカウントが有効ではありませんでした。そのためサービスごとにアカウントを切り替えてやり取りする必要がありました。これを変えていこうという試みです。</p> <p>blueskyは、<code>pds</code>, <code>plc</code>, <code>bgs</code>で動作することを予定しています。</p> <p>それぞれの役割を述べると、pdsがbluesky本体です。</p> <p>plcは<code>dns</code>のようなものでhandleとdidを登録し、名前解決を行います。</p> <p>blueskyは、基本的にpdsのみで動作します。</p> <p>しかし、アカウント作成時はplcに接続するため、plcへの接続がないとエラーになります。</p> <p>アカウントが作成されている状態ではplcは必ずしも必要ありません。handleの登録や変更があったときに必要になります。</p> <p>bgsは他のpdsとつながる際、アカウントのtimelineを構築します。</p> <div class="mermaid"> graph TD; A[pds]-->B[plc]; C[pds]-->B[plc]; D[pds]-->B[plc]; </div> <div class="mermaid"> graph TD; A[pds]-->B[bgs]; C[pds]-->B[bgs]; D[pds]-->B[bgs]; </div> <h4 id="dns">dns</h4> <p>上記のdnsとは何かというと、インターネット上で名前解決を行うサーバーのことを言います。</p> <p>インターネットでは<code>ip address</code>という数字で繋がります。</p> <p>例えば、googleに接続する場合は<code>172.217.25.174</code>です。</p> <pre><code class="lang-sh">$ dig google.com google.com. 291 IN A 172.217.25.174 </code></pre> <p>試しにブラウザにこの数字を入れてみてください。<code>google.com</code>につながるはずです。</p> <p>しかし、数字というのは人間にとって覚えにくく、扱いにくいものなので、通常は、アルファベットに置き換えた名前がつけられます。</p> <p>その名前を<code>ip address</code>という数字につなげる役割を持ったサーバーをdnsと言います。</p> <p>以下は、目的のホストまでの経路を表示するコマンド。いくつかのサーバーを経由して繋がっている事がわかる。</p> <pre><code class="lang-sh">$ traceroute google.com 20.27.177.113 17.253.144.10 172.217.25.174 </code></pre> <p>自分のip addressを知りたければ、<code>ipinfo.io</code>を使うと便利。</p> <pre><code class="lang-sh">$ curl <span class="hljs-_">-s</span>L ipinfo.io 20.27.177.113 </code></pre> <h4 id="plc">plc</h4> <p>現時点でよく使われているplcです。すべてbsky.teamが提供しています。</p> <p><a href="https://plc.directory" target="_blank">https://plc.directory</a></p> <p><a href="https://plc.bsky-sandbox.dev"
