All you need to know about Bitcoin .


The new currency that most people feel sceptical adopting. Bitcoin  is a digital currency that backers/investors of the cryptocurrency hope it will soon replace the traditional currency . A scare to Central banks. 

Bitcoin is used in online payment and transactions are recorded in a public ledger called  a  Blockchain   which was originally developed as the accounting method for the virtual currency.

A block records some or all of the recent transactions then goes into the blockchain as a permanent database.  After a block is completed a new block is generated.  The blocks would be in a chronological  order .

The blockchain would have addresses and user transactions stored in the blocks from the first block to the latest block added to the chain. The blocks are added through cryptography making it hard to be altered and the transactions cannot be deleted.  ( No more corruption) .

Relating to the real world,  block chains are like a full history of the financial institutions’ transactions and each block represent a financial statement for a user. 

 Blockchains use distributed ledger technology (DLT) . This simply means transactions are verified by other users.  Copies of the transactions are sent to different users to be verified. This makes it more difficult  for a hack to happen as it would have to hack all the copies of the transaction not only one. 

The verification  of the transactions brings me to the next important thing to know,  bitcoin mining. 

Bitcoin mining is the process by which transactions  are verified and added to the public ledger –  the block chain. Mining involves compiling the transactions into blocks and solving computational puzzles, the first user to solve the puzzle gets to place the block on the block chain and gets a reward.  

The reward is the transaction fees associated with the transactions compiled in the blocks and also users can receive newly released bitcoin. Sounds like a good business to venture in, keeping in mind that one bitcoin =  798,139  kenyan shillings  or $7,950   As of now writing this article.

The value of bitcoin has been on a downward trend, this may be due to IMF’s head, Christine  Lagarde urging on regulators around the world to crack down on cryptocurrencies citing that it may be a major vehicle in money laundering and financing of terrorism.  Google then went on to ban ads for cryptocurrencies.

Let’s  see how the cryptocurrency will be faring these coming weeks. 

Later on techies 🙌👋

Faiba sim card not compatible  with your device?  here’s  why


What do you look for when purchasing a smartphone?  To many people,  ram,  camera,  storage,  battery.  Not saying that’s not important,  it is.  

But to really enjoy what the service providers offer, we need to look at the nitty-gritty specifications.

The latest network we have in Kenya  is the 4G. It’s  only provided by only three service providers  the latest being faiba, the other two are Safaricom and Tellkom.  The network  uses specific frequencies and bands which vary across the network operators. This is what ultimately  determines if your phone will work with an operator.

Lets look at the frequencies and bands used by each network operator in Kenya 

Network            Frequency      Band
Safaricom          800 MHz         20
                           1800 MHz        3

Telkom Kenya   800 MHz         20

Faiba 4G            700 MHz         28

To come by smartphones having all the frequencies used by the network operators is tricky.  Both Telkom and Safaricom use 20 (800) while faiba solely uses  28 (700).

So your phone might be 4G enabled but it should also support the 700 MHz frequency and 28 band to be able to use a faiba sim card. 

The frequencies and bands are usually provided for as part of the product info when purchasing a smartphone. 

Here’s  a look at the different types of smartphones that support faiba 4G

    Mark Zuckerberg responds to the Cambridge Analytica scandal


    He chose to respond to this through his facebook page.

    Briefly all i can say is he’s assured facebook users that this cannot happen again, i mean if that’s what it takes to save your life’s work. 

    He started off by saying this

    We have a responsibility to protect your data, and if we can’t then we don’t deserve to serve you. I’ve been working to understand exactly what happened and how to make sure this doesn’t happen again. The good news is that the most important actions to prevent this from happening again today we have already taken years ago. But we also made mistakes, there’s more to do, and we need to step up and do it“.

    Then he went on to explain the timeline of events according to them how they handled the events as they unfolded until last week.

    He also said that the app that collected user data was developed before facebook limited access to user data, and such activity cannot happen again as they have developed measures.

    He finished his post by assuring users AGAIN 😒

    While this specific issue involving Cambridge Analytica should no longer happen with new apps today, that doesn’t change what happened in the past. We will learn from this experience to secure our platform further and make our community safer for everyone going forward.

    Is it time to part ways with facebook?

    You decide 😊

    Cambridge Analytica uncovered


    Its probably the top headline around the globe, Cambridge Analytica.

    Well, what is it?

    Cambridge Analytica is a data analysis firm. It collects data on users, raw data, on the internet and make constructive information that help in creating tailor made advertisements, That’s pretty much how data analysis firms operate.

    But how different did Cambridge Analytica conduct its business.

    What really happened?

    The company partnered with Facebook collecting user data on Facebook users. The info of which would only be for research purposes. At least, that’s what they told Facebook.

    The company developed an app, ‘thisisyourdigitallife’ which many fb users downloaded not knowing by pressing the download button they are giving out their personal info and that of their friends to the company.

    With that kind of information like what people like, dislike, where they live and there Friend’s info too, Cambridge Analytica would build profiles using the collected data. Which would help in the political campaigns.
    The Trump campaign invested heavily on Facebook, especially in the last few months leading to the election. All of its campaign advertising on the platform was led by Cambridge Analytica data.

    According to reports we do know Chief Security Officer Alex Stamos, plans to leave the company in August over the way executives are handling the scandal.

    Zuckerberg had this to say relating to the cambridge Analytica scandal

    Relating to the Kenyan elections between 2013 and 2017, the managing director, Mark turnbull said this to an undercover investigative reporting team from channel 4 “We have rebranded the entire party twice, written the manifesto, done research, analysis, messaging. I think we wrote all the speeches and we staged the whole thing – so just about every element of this candidate,”

    He was regarding to Kenyatta’s political party known as National Alliance until 2016 then named Jubilee afterwards.
