The only good thing a blockchain is good for is to log every single transaction for every single satoshi ever spent. No place to hide your electronic coins. That is so funny that the fake decentralized system is sold as the opposite. Freedom loving people are fooled(greed wins) into embracing something that will be the greatest tool in their enslavement.
The good folks from steem worked out many of the bugs in the new enslavement currency. This current thing called blockchain is the tyrants wet dream for exchange. But its is like windows 98 already. Have you heard of the new open ledger system called HBAR It spanks all into the ground.
Every transaction is logged and unapproved transactions will not occur.
