FIMK 0.3.3 is based on NXT 1.2.6.
This is a hard fork everyone MUST update to this release.
This release and all future releases blacklist any peer that is on or below
version 0.3.2.
On startup a one time scan and verification of the blockchain will be performed.
Deleting your folder blockchain is not required for this update.
About the hard fork:
On Friday December 19th 2014 we were informed of a theft of 57 Million FIMK
from a user's account by a hacker, who gained gained access to the accounts
through the user carelessly sending his account passphrases to a rigged public
node. The hacker transferred a total of approx. 57 Million FIMK from several
accounts to 59 other accounts, each account receiving roughly 1M FIMK.
In total this amounts to 13.9 % of all FIMK in existence at this time.
As the portion of stolen funds is a significant portion of the total FIMK in
circulation, the association is obliged to intervene. To avoid a situation
where FIMK would at the mercy of a thief in possession of a large portion of
total funds, strengthening her stake by forging constantly and thus gaining
undue control of the network, AND likely dumping some of the large stash
constantly rendering the remaining FIMK worthless (as has happened before with
other coins in similar large scale incidents) the association decided to freeze
the hacker assets by releasing customized emergency version of the FIMKrypto
server which does just that.
This release temporarily seals the stolen FIMK in the protocol making them
untouchable by no one, not even by the association. This is done to prevent
mixing of the stolen funds through further transfers to obfuscate the origin,
which we were able to prevent just in time. The following steps and measures
to be taken for the frozen stash are discussed with the community and decided
on the basis of those discussions.
Mandatory update
Earlier server releases (before 0.3.3) are blacklisted by default to prevent
the chance of future forks and keep the network coherent.
Hacker accounts locked
There are 59 accounts identified that hold the stolen FIMK, the public keys to
these accounts are locked from making outgoing transactions and are not allowed
to forge blocks.
