SAFE Network concerns from an old employee

Have you seen something closer to an actual algorithm or description? There are some critical parts missing. How do the other nodes verify that there was no collusion when generating the ID?

Wait a second, you made the following statement some time ago:

@vtnerd

I think the second major problem is related to the close group attack mentioned on Google Groups, but I failed to bring another thought to attention (I will take the blame for that). The “closest” public-key in terms of XOR space is determined by the longest prefix. This indicates to me that the person with the most computing power can generate the highest number of closest keys, and this person will be capable of setting any desired value immediately.

So you said that people can target an address when they have “the most computing power” and when I point out that this isn’t the case as one can’t choose it’s own address in the network you ask me for an algorithm? So you didn’t had a clue in the first place then? Just firing some shots around without knowing how this stuff really works? Here’s a diagram by the way.

We are talking about different things. In my prior posts “partition” is referring to the possibility that multiple SAFE networks could exist simultaneously. For instance, imagine if a data center went offline entirely. The SAFE nodes inside the data center will think that the remainder of the world lost connection, and continue to operate.

No they can’t. The network operates on XOR-level as you know. It doesn’t really care about IP’s. So when a datacentre goes down with 1000 nodes, chances are extremely big these nodes are in 1000 different groups. So if each group has 12 nodes active, they all go from 12 to 11 and there is no problem at all. The 1000 nodes can’t do a thing on their own as they’re removed from the groups they were in.

@vtnerd

I strongly dislike the current group design that never tries to achieve consensus with other members of the group.

Group Consensus is one of the basics of the SAFE network.
