Siacoin to Undergo a Hardfork on Jan 21

The hardfork of Siacoin will occur at block 139,000 on January 21 to ensure that when ASICs begin mining Siacoin in 2018 the change in hashrate will not break Sia's consensus functionality

The moderator of the official Siacoin thread on Reddit has presented the information regarding the upcoming Siacoin hard fork. It will occur at block 139,000, and will not result in new coins, because this is going to be an uncontroversial hardfork and the development team has not expressed interest in supporting it.

Moreover, it is known that there are two separate hardforks, and the first one have already occured at block 135,000, on December 6, 2017. But that hardfork contained an unforeseen bug, which became the reason for Siacoin to undergo a second hardfork, which will occur at block 139,000.

The main reason for the upcoming hard fork is that the difficult adjustment algorithm of Sia needs a change to make sure that when ASICs begin mining Siacoin in 2018, the massive change in hashrate will not break Sia's consensus functionality.

After the fork occures, the block times will be reduced from 30 minutes to 10 minutes, and for Siacoin miners it will bring mining yields back to the same level they were before the first hardfork.

Earlier today we have reported that AntPool, one of the largest crypto-currency mining pools, added support for the mining of the Siacoin token.

At the moment of press, these are the main market parameters of Siacoin:

  • Average price: $0,050988
  • Market cap: $1 600 832 980
  • 24h volume: $104 331 000

Microsoft Word Has Mining Vulnerability, Votiro Says

According to researhers, vulnerability is caused by the new feature of Microsoft Word

Java mining scripts for Monero can be run inside Word documents. This became possible thanks to a new feature that appeared in the latest versions of Microsoft Office products. It allows you to add text to the video using the iframe insertion code. The file itself does not become harder, because the view is done online. This is reporte by Block Tribune.

The problem was noticed by a researcher from the Israeli company Votiro Amit Dori. He writes that the video player is actually a disguised Internet Explorer browser that operates in an offline mode. In addition, Word allows you to insert links to any site on the Internet, even if it is not in the white list.

You can protect yourself by maintaining an up-to-date machine with all security patches and updates installed. Furthermore, if you spot a serious CPU rise while watching an online video in Word, be aware it might be an in-browser miner and close the video frame.

The scammer can place the video in his own domain, adding to it a Java-script for mining. It is worth the user to click on the playback, as the crypto miner starts to mine Monero, parasitizing on the power of its processor.
