Can you describe how a snowflake ID would help? Imagine the data contains two Rare Items, when it should only contain one instance. They both have different snowflake IDs. How do you determine which is authentic? The timestamp on the duplicated item could have been spoofed.

I think the real solution to this problem is just to trust a centralized actor and single large database that is shared across all servers. Not what the author wants to hear, but most games don't need the level of decentralization of PoW or PoS for all of their game assets. But a fully decentralized MMO would be cool in theory.
