Can't worms simply relay to each other the message signed by the botnet master? No Sybil attack there.
The trend of throwing blockchains at problems for which they are totally uncalled for is profoundly annoying.
- kordless 12y agoThe use of the blockchain here appears to be based on the fact shutting down the Bitcoin network is considered to be impossible, at least for the immediate purpose of stopping the control of a botnet. I assume a Sybil attack can still occur within a peer-to-peer network that uses signed messages because of the location and addresses of the nodes can't be signed as well. i.e. the node you are talking to may be repeating previously re-transmitted signed messages, or simply not sending messages at all. It's not as if the master can sign a message vouching for the entire network's current state...
