Our implementation of epidemic routing allows anyone to create new messages that are then propagated by everyone else. This makes it very easy for an attacker to flood the network with useless messages.
Currently using Bitcoin's proof-of-work to make it difficult to jam the network with useless, but that PoW is vulnerable to mining ASICs that can sign messages relatively inexpensively.
Ideas to consider
- Ethereum's PoW, Ethash, requires lots of memory so it's not vulnerable to ASICs
- Zero-knowledge proof
