What are the disadvantages of sync?

I'm curious, what are the potential drawbacks of using synchronization, or 'sync', in the context of cryptocurrency and finance? Could it lead to delays in transactions? Are there any risks of data loss or inconsistencies arising from synchronization issues? Additionally, could it impose significant overhead on the system, affecting performance and scalability? I'm interested in understanding the full picture of what one might be sacrificing when opting for sync in these complex financial environments.
