Network analysis deflates Bitcoin’s anonymity myth

Charting transactions from an alleged theft

Censorship and jurisdiction in Turkey

The Turkish Internet has been crippled in recent weeks due to an unprecedented conflict between the Turkish courts and Google. If you are not familiar with the background to this case, you will find some excellent write-ups in various places (such as this BBC summary).
