I've heard that Iran has hacked Israel's SSV blockchain (allegedly operated by Mossad and used to pay operatives) and obtained 8 TB of personal information about who their operatives are.  Do any of your blockheads know anything about this blockchain and if this could possibly be? 

 > who their operatives are

They are Jews. 

 What means hacking a Blockchain and revealing data? A centralized Blockchain is useless afaik
