Heiamback talks about "grassroots technological anonymous crypto-currency", I wonder if by this he means Bitcoin or a totally anonymous currency without a public ledger like Monero.
Monero has a public ledger which attempts to provide anonymity via autonomous mixing with Cryptonote's one-time ring signatures. Monero does not have anonymity of the IP address sending the transaction to the public ledger, thus it doesn't have total anonymity. Fluffypony was proposing to add I2P (a.k.a. Darknet) integration, but I don't think any free onion routing "darknet" network can be resistant to Sybil attacks on anonymity. We've seen the Tor "darknet" fail spectacularly with its hidden services.
Anonymity is difficult with Bitcoin (but not impossible if you are expert). Bitcoin is an important bridge between the legal tender national currencies and the altcoins.
There are many technologies in play here, and there are more coming. Stay tuned.
As far as I know Tor never got compromised given the guy hosting the hidden service didn't do anything stupid, which has been the case every single time. It's like saying Bitcoin is not secure because all those exchange hacks. If you keep your Bitcoin with you in a safe computer they are safe, if u run Tor with no javascript etc in a safe OS and dont reveal private information you are safe imo.
