Merkwürdig find ich die Aussage, daß Bitcoin mit der US-Regierung zusammenarbeite,
wie kann denn Software/Code/ein Protokoll mit der Regierung zusammenarbeiten?
Ob dies den Bitcoin betrifft ist die Frage bzw. dürften ein Geheimdienst 'der kann' dieses Wissen gut für sich behalten.
https://bitcointalk.org/index.php?topic=206630.0In between theory and practice, was Moty Yung's very entertaining invited talk about Kleptography -- using cryptographic techniques for offensive, malicious purposes, rather than defenses, typically against other cryptographic systems. As an example, he gave a public-private RSA key generation algorithm, which is indistinguishable from an honest, random one in a black box manner, and even if reverse engineered, the keys generated with it can be factored only with the effort of factoring a key half that long. The attacker, however, that pushes this key generation algorithm on unsuspecting victims, will be able to factor their keys with very little effort."
