0.000 HBDHardfork 13: Minimal Steem power to vote + Steem mining bug fixed
<html> <p>The <a href="https://github.com/steemit/steem/releases/tag/0.13.0-rc3"><strong>hardfork</strong></a> scheduled for Mon, 15 Aug 2016 14:00:00 GMT will include the following releases:</p> <p>http://i.imgur.com/ZEfZa81.jpg</p> <ul> <li><a href="https://github.com/steemit/steem/issues/248"><strong>minimal rshares per vote will now be enforced</strong></a></li> </ul> <p>This effectively stops accounts with really low amounts of steem power from voting. Preventing spam of meaningless votes. This update was made with the intention of preventing bot attacks.</p> <p><br></p> <ul> <li><a href="https://github.com/steemit/steem/issues/256"><strong>new proof of work algorithm that prevents short cut calculations </strong></a></li> </ul> <p>After the recent mining attack by a user named 'supercomputer' the steemit devs have been working hard to fix this bug. 'Supercomputer' did this attack by skipping the hashing part of mining and using ECDSA instead. The hacker could submit new blocks, using old blocks and changing their block-id. Then change his private key to sign the new block, effictively skipping the POW. <strong>@arhag</strong> will soon fully disclose how all of this took place.</p> </html>
