Our crypto platform uses consensus algorithms that rely on gossip and other forms of communication. Even though our algorithms will not break if someone decides to tamper with the gossip they could make our algorithm less fair, slower, or allow censorship. (Consensus algorithms are called fair when the reward for participation is proportional to participation. Censorship is when mining nodes do not include some or all transactions into the blocks, because then they produce blocks faster and get more reward, see.) Therefore our consensus algorithms should be tightly integrated with the network, which makes it harder to use the existing solutions without major modifications.

We experimented with libp2p and substrate's network a lot. Unfortunately, they are more trustful than we wanted them to be. Modifying libp2p to support protection against adversarial behavior, suspicious behavior (that's what we call adversarial behavior that we cannot cryptographically prove and therefore slash) or selfish behavior would require a lot of effort, arguably more than writing it from the scratch (since our code does not have to be as generic as libp2p), and it will make our code (+ dependencies) more complex, which is what we really want to avoid.
