Satoshi Nakamoto`s last message:-

“There’s more work to do on DoS, but I’m doing a quick build of what I have so far in case it’s needed, before venturing into more complex ideas. The build for this is version 0.3.19… Added some DoS controls.

As Gavin and I have said clearly before, the software is not at all resistant to DoS attacks. This is one improvement, but there are still more ways to attack than I can count. I’m leaving the -limitfreerelay part as a switch for now and it’s there if you need it.”
