Bitcoinの開発者を名乗る人が現れました。オーストラリアの起業家であるCraig Wright氏は，自身がBitcoinを発明し，Satoshi Nakamotoのペンネームで公開したと述べております。Wright氏はBitcoinを開発したことの技術的な証拠をいくつか提示してきました。しかし，業界の専門家は，より多くの証拠を示さなければ，Bitcoinの考案者であるという証明にはならないと述べております。
記事の中で気になった単語は"cryptographic"です。『Wisdom英和辞典第三版』(三省堂)には"cryp･to-"で「秘密の, 隠れた」という意味がありました。Oxford Dictionaries.comには"cryptograph"で"A coded message"と定義されております。今回取り上げた単語は語尾に"ic"がついており，形容詞となると思われます（http://www.k5.dion.ne.jp/~arcen/newpage3.html）。したがって，"cryptographic"で「暗号の」と訳せると思います。（Ume）
Craig Wright revealed as Bitcoin creator Satoshi Nakamoto
Australian entrepreneur Craig Wright has publicly identified himself as Bitcoin creator Satoshi Nakamoto.
His admission follows years of speculation about who came up with the original ideas underlying the digital cash system.
Mr Wright has provided technical proof to back up his claim using coins known to be owned by Bitcoin's creator.
Prominent members of the Bitcoin community and its core development team say they have confirmed his claims.
But many others in the Bitcoin world are asking for more proof.
Signed blocks
Mr Wright has revealed his identity to three media organisations - the BBC, the Economist and GQ.
At the meeting with the BBC, Mr Wright digitally signed messages using cryptographic keys created during the early days of Bitcoin's development. The keys are inextricably linked to blocks of bitcoins known to have been created or "mined" by Satoshi Nakamoto.
