ZIL – Storing Zilliqa on Ledger

Z

There is a difference between a Ledger NanoS and a NanoX. ZIL is one of those differences. In order to store you ZIL on a Ledger you need to store it on a NanoS. If you plug in your Ledger NanoX and search for ZIL, you will find nothing. But if you do that same search while your NanoS is installed you will find the app. The official Ledger Support page for ZIL.

Swapping ETHOS, BQX to VGX

S

The question came up on how you can swap your ETHOS and BQX to VGX. I’m not exactly sure when the rebranding occurred, but ETHOS was rebranded to VGX. You can read the official announcement. But if it’s been rebranded, do you need to swap your coins for new coins? Here is the answer from someone in their tech support group.

Hi,

The Voyager Token (VGX) was previously trading under both BXQ (Bitquence) and ETHOS (Ethos). Not all exchanges or wallets have been able to make appropriate updates to the display name and ticker when these rebranding efforts took place. Binance, in particular, still shows BQX (The Voyager Token) as the ticker symbol and name. Some other wallets and exchanges still show ETHOS.

However, the underlying ETH contract for the token was never changed when the display name and ticker was rebranded. You can seamlessly send funds to and from any exchange or wallet regardless of the name being different. No token swap is needed. BQX, ETHOS and VGX will be received properly across exchanges or wallets even if the display name is not matching.

Kind regards,KELSEY  | CUSTOMER SUPPORT |  ETHOS

Keeping Things Private On Telegram

Here are a few things you might want to do to keep yourself private when using Telegram. All these setting can be found in Privacy and Security settings. These are suggested settings and set them to what you feel comfortable with.

*** IMPORTANT ***Are you tired of being added to a random Telegram channels? I’ve been added to bogus, impersonated Telegram Channels which I thought and appeared to be the original channel i joined. Make sure you set #5 to My contacts.

Privacy1. Hide your Phone number – Set Who can see my phone number to Nobody – Set Who can find me by my number to My Contacts – Add exceptions if you’d like2. Turn off Last seen & online – Set Who can see my last seen time to Nobody – Add exceptions if you’d like3. Set a Profile photo that’s not who you really are – If you would like to set your real photo – Set Who can see my profile photo to My Contacts4. Set Voice calls – Set Who can call me Nobody. Use Signal instead.5. Set Group & channels invite settings – Set to My contactsOtherCheck your Show all Sessions – Check to see if you are signed in on other devicesYou can set a local password with Turn on local passcode – this option sets a password for local accessEnable Two-step verification – It is a email 2FA.

Ad-blocking For YouTube

A

I’ve had a few people ask what I used to block YouTube Ads. If you are NOT running a Pi-hole, this combination might work for you.

Use Brave BrowserUse this Chromium browser plugin –

I’ve heard that the above plugin might not work well when you use it with Google’s Chrome, but that just make sense. It might break a few times, but then they release an update for it and it’s back to no more ads in YouTube.

But if you want the simplest way to block all types of ads, including on YouTube, think about adding a Pi-hole to your network. I’ve almost forgot what ads look like. Honestly, I’m not kidding. Look at the examples below. A Pi-hole is also great for blocking tracking.

ADA Delegating

Here is a great article walking you through the steps of delegating your Cardano ADA.

Below is a quick video on how to stake your ADA on the adalite.io wallet delegating with adalite.io. Staking has been pushed off until August 13, 2020. Payouts won’t be received until August 23rd. See delegation cycle below.

Epoch = 5 days

A few words from AdaLite.ioplease be aware that there are multiple websites mimicking AdaLite interface that are trying to steal the keys to your wallet. Please make sure you check the URL in your browser every time you visit AdaLite that it matches . Never give your mnemonic seed phrase to anyone. 

Horizen – ZEN

H

Below is some information on Horizen’s ZEN and how you can use the ZEN Faucet to earn free ZEN daily.

Main website – website –

The coin can be stored on 2 hardware wallets, Ledger & CoolWallet. There is also a variety of other wallets that you can use –

Free ZEN Coins

ZEN has a Faucet @ The ZEN Faucet can be used ever 20 hours for free ZEN.

It gets a little involved to set up. It requires a @gmail address to have an account set up. If you do set up a ZEN account to use the Faucet, you have to download and install their Sphere desktop wallet. My first attempt while using a test NordVPN account out of London failed. I then tried again using CryptoLab VPN out of Atlanta and everything went through fine.

You are forced to use a @gmail address to sign up for an account. You are incentivized to verify your ZEN address, use a Brave Browser, add social media like FarceBook, Twitter & Linkedin. If you come back each day and get more free ZEN, you also recieve bonus ZEN.

*** Notes ***You might get an error if you use a VPN and come from a different IP address. I found this to be the case. Just come from one IP address and you shouldn’t run into any issues.

Pi-hole Where To Place It On Your Network

P

Re-configure your router so that Pi-hole is the DNS Server for your network

To have Pi-hole automatically used by all the clients on your network, you have to reconfigure your home/office router to use a different DNS server. If you have never tinkered with the settings on your home router, this may be a little challenging.

Your first step is to find out the IP address of your router and log into it with a web browser.

You Have Two Choices For Router Configuration

Most users at this point will have to make a choice when it comes to changing the configuration of their router:

Some users may have no choice but to go with the ‘red pill’ option and have to disable DHCP services on their router because they do not get the option of changing DNS Servers. Let’s discuss these options properly.

The Blue Pill: Change the IP address of the DNS Server your router uses

This setting will have minimal impact on your current network setup. By default, most routers will make themselves the DNS Server for clients on the network. By replacing the DNS server that your router uses with Pi-hole’s DNS server, it will mean all the devices on your network which get an IP address from the router, will use Pi-hole for DNS. Some routers, like my own, may allow setting the DNS server in the configuration for the DHCP service.

Log into your router as an administrator.Set the primary and secondary DNS server to be the IP address of your Pi-hole. See the image below and follow the Blue Text.There are too many different routers give step-by-step instructions on changing the DNS server settings, if you get stuck, try searching for the model of your router and the phrase “change DNS server settings”.Save the setting on the router, and reboot all of your devices and that’s it! You’ve now got the basic Pi-hole ad blocking enabled for your entire network!

TIP: Some routers will want a primary and secondary DNS Server. If your router requires two values, try putting in the IP address of your Pi-hole for both primary and secondary.

If you cannot make these above changes to your router because it has been locked-down by your ISP, or the router you are using does not support the option, you will have to choose the ‘red pill’ option below.

The Red Pill: Disable your router’s DHCP service and have Pi-hole take over

DHCP is the protocol used to give out IP addresses to devices on a network. A service running on your router typically does this. You can disable this service on your router, and have Pi-hole take over performing the DHCP service. You may not wish to do this right away, but once you get a feel for the Pi-hole console, this is something you will want to do. On my network, I have Pi-hole take over DHCP so that local network name resolution works appropriately and Pi-hole can identify devices in its audit log by hostname instead of IP address.

Log into the Pi-hole administrator console  where 192.168.x.x is the IP address you have set for your Pi-hole.Click on the settings menu on the left-hand side.Under settings, there should be a section for turning the Pi-hole DHCP server. Click the checkbox to enable DHCP. The default settings provided should be ok. Just check that the IP address range makes sense for your network, and that the router address is correct. I personally like setting the DHCP lease time to be at least a day. For further discussion about these settings refer to this page.Once you have reviewed the DHCP options and clicked enable, click Save.Log into your router and disable DHCP (make sure you do this after you turn on Pi-hole’s DHCP). if you get stuck, try searching for the model of your router and the phrase “disable DHCP”Reboot a device on your network and reload the Settings page on your Pi-hole and expand the DHCP leases control, you should see the name of the device you restarted come up in the list.You should now have Pi-hole running DHCP services on your network.

Where To Get A Pi-hole

Pi-hole Update Software

P

How to update your RaspberryPi OS Running Pi-hole

To update software in RaspberryPi OS, you can use the apt tool in a terminal. Open a terminal window from the taskbar or application menu.

First, update your system’s package list by entering the following command:

sudo apt update

Next, upgrade all your installed packages to their latest versions with the following command:

sudo apt-get upgrade

The commands you just ran will update the operating system (OS) on your Pi-hole, but will not update the Pi-hole software. You need to run the commands below to update the Pi-hole software.
If you are running your Pi-hole as a truly self-contained DNS resolver via Unbound, make sure to update your /etc/dnsmasq.d/01-pihole.conf file

The command below will show you the version your Pi-hole is running

sudo pihole -v

The command below will upgrade your Pi-hole to the latest version

sudo pihole -up

Generally speaking, doing this regularly will keep your installation up to date for the particular major Raspberry Pi OS release you are using (e.g. Stretch). It will not update from one major release to another, for example, Stretch to Buster.

Use the following command to reset your password

pihole -a -p

Install Pi-hole –
