SCMT news

New Website Launched!

In March 2018 SCMT created a plan to design and build a new website for the Syscoin community. We wanted to create a platform where the existing community and newcomers alike could find information about Syscoin, and submit their own content in the form of articles, meetup announcements, ICO info, news updates, tutorials, FAQs, and information on existing and forthcoming features.

Additionally, we are also able to publish information via the community website that BCF cannot legally share, such as information about upcoming ICOs, airdrops and other projects on the Syscoin chain.

Special thanks to our slack member @aegisker from http://dotline.si for building the website! We are proud to present Syscoin.community - enjoy your stay!

Technical Updates

Poloniex

The Poloniex wallet is now running on the 3.0 chain and they have opened up their wallets for withdrawals and deposits. Coincidentally, today 24 new Masternodes came online!

Syscoin Qt 3.0.5.

New Qt wallet release: Syscoin Qt 3.0.5. You can find it here. As stated above, upgrading to Syscoin Qt 3.0.5 is mandatory. Upgrading Sentinel to 1.1.1. is mandatory for all masternodes. Instructions for the mandatory upgrade for Qt 3.0.5 are:

Step 1: Login to the vps

Step 2.1: If you used Justin’s script, run this command and choose ‘y’ to upgrade

‘bash <(curl -sL https://raw.githubusercontent.com/einalex/syscoin-scripts/master/masternode.sh)’

Step 2.2: If you used BCNF’s manual guide instead, run these commands in vps:

`~/syscoin/src/syscoin-cli stop` `cd ~/syscoin` `git checkout master && git pull` `./autogen.sh` `./configure` `make -j$(nproc) -pipe` `~/syscoin/src/syscoind` `cd ~/syscoin/src/sentinel` `git checkout master` `git pull`

Masternodes

At the moment of publishing there are ~1113 masternodes online.

Masternode daily reward calculation: 37411.2 SYS per day divided across the number of active masternodes (Currently ~1064).

‘Seniority’ will get you +3% ROI on your block reward for every 4 months running your MN. For example, after the first 4 months, you will get 25.98 + 3% = 26.77 rewards per block.

Latest release wallet for creating/managing masternodes is QT 3.0.5. Latest release for Sentinel is 1.1.1.

Checking masternodes

You can check your nodes with your server console on your server (e.g. Putty). Uptime of your master node can be checked by inserting this line into you server console (e.g. Putty):

syscoin-cli masternodelist activeseconds | grep [your IP address]
