+Blockchain is a P2P network - and Smoldot tries to connect to a variety of nodes of this network.
 Imagine if all these nodes were to refuse sending data back, that would isolate smoldot from the network - The way that smoldot learns which nodes exist (GOSSIP) is from the nodes themselves (bootnodes).
-If smoldot is only ever connected to malicious nodes, it won&#39;t ever be able to reach non-malicious nodes - if the list of bootnodes only contains malicious nodes, smoldot will never be able to reach any non-malicious node.
+If smoldot is only ever connected to malicious nodes, it won&#39;t ever be able to reach non-malicious nodes
 If the list of bootnodes contains a single honest node, then smoldot will be able to reach the whole network.
 !!! this attack is effectively a denial-of-service, as it will prevent smoldot from accessing the blockchain!</p>
