I'm quoting Anonymint from another thread where he talks about I2P on top of anonymous coins, to ask a development question on how we can implement I2P in Darkcoin.... I've bolded the part which I want to highlight:
However, these low latency networks admit in their FAQs that they are not able to obscure from an adversary who can see both the entry and exit traffic because timing analysis can be employed. If you only have a few pools, then the exit nodes for mining shares and transactions should be known and hackers can target their ISP or upstream router (correct me if I am wrong).
Regarding DRK, I2P integration is planned because without IP obfuscation, anonymity is bust... so, my question is this: Can an I2P network (or the wallet?) be configured in such a way as to group broadcasts at certain time intervals? Like once per minute at 13:56:00, 13:57:00, 13:58:00, 13:59:00, 14:00:00 etc. In this way it would be much more resistant to timing-analysis (or so I figure - may be wrong).
Just throwing thoughts around.
