Why did STEEM blockchain froze ?

Apparently someone initiated a transfer ? of negative VESTS (VESTING SHARES)

THERE IS NOTHING TO BE PANICED ABOUT

Once the chain comes back, we should be able to see the transactions and get more details.

the details of the fix:

We can see the following changes in the code and an account nijeah

auto account = find< account_object, by_name >( "nijeah" ); if( account != nullptr && account->to_withdraw < 0 ) { auto session = start_undo_session( true ); modify( *account, []( account_object& a ) { a.to_withdraw = 0; a.next_vesting_withdrawal = fc::time_point_sec::maximum(); }); session.squash(); }

nijeah

So it seems the account had withdrawn -1,000,000,000,000 VESTS from vesting balance! yea, NEGATIVE!!!!!.

Basically powerdown!

7 days ago Start power down of NaN STEEM
7 days ago Start power down of NaN STEEM
7 days ago Start power down of NaN STEEM
7 days ago Start power down of NaN STEEM

Now, (-1,000,000,000,000 ) will make the total STEEM in supply to negative and thus the blockchain on its knees.

@nijeah vs @haejin

I love this bug for the account which is used to demonstrate the bug.

All hail @haijin and @nijeah :-D

Michael Vandeberg (@vandeberg) : Appreciate your hard work and the fixes. Hats off to you!
