June 20 UPDATE – We are pleased to announce ZenCash 2.0.14 for Linux is available. All node operators, exchanges, and pool operators must update from the previous version before June 28th when the current version is deprecated and will stop working (at block 332576). – Source ZenCash Blog

BUILDING FROM SOURCE

To upgrade from any version prior to 2.0.14 you will have to re-clone the repository. The ZencashOfficial/zen repository was replaced by a new repository based on Zcash upstream with a different commit history, merging/pulling is not possible without issues.

Refer to detailed instructions to build from the source to update the zend daemon.

What is required to host ZENCash Super Nodes

We are hosting ZenCash Super Nodes – check here!

ZenCash team recently announced the plans to add Super Nodes to the ZenCash network by the end of 2018. This step will place ZenCash to be much more than a cryptocurrency.

An updated white paper has been released this week outlining greater details, for more information please download ZenCash Supernode White paper.

Within just three months of launching their secure node system, ZenCash’s network has reached over 9000+ nodes. If you are interested in hosting your secure node, we are here to help you. Please contact us for more details or visit our thesecurenodes.com.

What is a Super Node?

 

Basically ZenCash Super Nodes will be even more powerful than Secure Nodes, tasked with managing key network and system functions, including hosting multiple services on sidechains, tracking and measuring Secure Node uptime, and queuing the node payment schedule for miners.

Super Nodes will ensure the utility not only of ZenCash as a currency, but also the future services that will be layered in the infrastructure.

What is a requirement for Super Node?

Super nodes must follow higher criteria:

At least 500 ZEN in a t-address for staking
Multiple CPU cores
8GB of RAM or more
100GB of storage or more
96% node uptime per day
Our target Super Node and Secure Node counts are between 2000-2,500 Super Nodes and 20,000-25,000 Secure Nodes, respectively.

When is Super Nodes going to be released?

As mentioned earlier ZenCash team is planning to add this functionality by end of 2018. The testing may begin sometime in July 2018 though.

What is the reward payout for Super Node?

The current block reward will be changed from 3.5% to 10% secure nodes, 10% supernodes, 10% treasury, and 70% miners. Good news, isn’t it? If you would like to find out ROI, you may visit ZenCash ROI Calculator.

An updated white paper has been released this week outlining greater details, for more information please download ZenCash Supernode White paper.

Is TheSecureNodes Team going to provide Super Nodes hosting?

Of course yes, we are, managed services company, we currently provide managed hosting for secure nodes. We have plans in place to start managed hosting for Super Nodes as well.

For any queries please contact us. We are available on WhatsApp as well.

Update ZEN Secure node zend daemon

As we all know Zen version 2.0.11 has been released to solves some blockchain indexing issues on secure nodes. The current version 2.0.10 will be deprecated in April and hence all Secure Nodes need to be updated before then.

For higher up-time and better performance, we recommend using Contabo VPS for hosting secure nodes.

Here are few simple steps to update the zend daemon on your ZEN secure nodes:

  • Updating the zend daemon from new APT repo:

The APT repo has just been updated with the SSL/TLS bug fix. To install the updated daemon with minimal downtime you can do the following:

sudo apt-get update
sudo apt-get install zen
zen-cli stop (then wait for 5 seconds)
zend

You can verify that you are at the latest version by running:

zen-cli getnetworkinfo | grep version

 

  • This process will only work for those who built their zend from source not the APT repo:

To update the zend daemon on your secure nodes you would have needed to have built your zend daemon from source. If you did this, you can update your secure nodes by running the following:

Navigate to the zen directory, if you followed mine or Blockops guides this will be located in the zencash directory:

cd ~/zencash/zen/

Next we need to fetch the updated code:

git fetch origin
git checkout master

Note: if it asks you to ‘git pull’ please run

git pull

Now we need to build the daemon:

./zcutil/build.sh -j$(nproc)

Now we need to stop the zend daemon and update zend and zen-cli binaries in /usr/bin. This can be done by running the following commands, if you use monit to run your zend daemon.

sudo monit stop zend

wait for 5 seconds and then run:

sudo cp src/zend /usr/bin
sudo cp src/zen-cli /usr/bin
sudo monit start zend

If you do not use monit on your secure nodes you can stop the daemon by running:

zen-cli stop

(wait 5 seconds)

sudo cp src/zend /usr/bin
sudo cp src/zen-cli /usr/bin

And finally starting the daemon again:

zend

You can verify that you are at the latest version by running:

zen-cli getnetworkinfo | grep version
