The peer-to-peer network is more vulnerable to low level network attack, than the ever-discussed 51% hashing attack.

You can help, by running a full node that accepts incoming connections.

I am not suggesting a 51% attack is the greatest threat to bitcoin, quite the opposite in fact. A redundancy of 29 is overly redundant a wasteful. I would sleep well at night if it only had a redundancy of 8.

What do you think a good level of redundancy would be?

What redundancy give us is a means of judging relative computational capacity. You could use redundancy to judge the relative growth or contraction of computation strength over time without having to cancel out the effect of Moors Law.

How close are we to a low level network attack, and how are you calculating that?

@hazek. Why have you moved this post to mining? It's about judging bitcoins relative computational strength not mining.

As I explained above, your concept of redundancy is based on an arbitrarily chosen value of "external power". Therefore, it is not a a particularly useful measure of anything.
