Having risks to be potentiall abused by attackers are good. It's good for investors to see the announcement that emphasize PHORE has zero risk, and does not the same as other Zerocoins. Unfortunately, I still don't know how the PHORE team can make it. The image shows Synapse, so what are main mechanism of the Synapse that can help PHORE become zero-risk coin. Being a zero-risk coin is amazing, but it is clearly a very ambitious target because attackers don't feel tired with their efforts to find out weaknesses of networks to do their attacks and steal money.
Synapse is a sharding architecture which means they can have different privacy protocols (Zerocoin / Ring CT....etc) on different shards. This means users can have a choice of what Privacy protocol they use provided there is a shard built for it.
