We believed all along for last three yrs that steem is immutable and decentralized. And we all now discover that that was not the case ever.
How now to believe that Hive will honour these attributes of immutability and decenralization. How did me make sure that what happened on steem will not happen on hive
Every single thing I've ever posted is immutably maintained. Steem (in my opinion) renamed to Hive in HF23 and defended itself very well from a very serious and well-financed attack made possible by the ninja mined stake and the centralization of Steemit, inc. Both of those things do not exist on Hive.
That said, there are still improvements to be made to further secure Hive and prevent this from happening in the future.
