Huawei just recently joined the league of notch smartphones with the release of Huawei P20 and P20 Pro smartphones. The Huawei P20 being the obvious cheaper variant with more comparatively modest specs. The smartphone features a nice hardware and an impressive design to go along with it. The new smartphone has some interesting features with slight upgrades compared to the Huawei P10, its predecessor.

The Huawei P20 qualifies as a good looking smartphone and has a solid build. Considering that recent high-end smartphones have a glass build which is what you have here. The smartphone is attractive because of this and shimmers when light shines on it. While this is good aesthetics, there are numerous available colour variants available which varies on how flashy it appears. It also comes with no audio jack which will certainly be missed by many.
In the display, it has fairly impressive Full HD panel installed on it. Although this us not has impressive like what you have on the more premium Huawei P20 Pro and instead of the OLED screen, the Huawei P20 has only an LCD screen. Rather, it has a resolution of 1080 X 2244 pixels and a pixel density 428 ppi.
Battery and CameraIn terms of battery power, the smartphone comes with just enough to give you ideal daily usage time. Taking power from a 3, 400mAh Li-Po battery, the smartphone should be able to go a day on slightly intensive usage. You could also charge through the USB Type-C port with the fast charge technology feature .
Going along with the recent tide of smartphones, the Huawei P20 has a dual rear camera. The rear side as a 12MP and 20MP camera with flash for more light. On the front side, there is a 24MP camera with AI integration common in premium smartphones lately. This helps in taking better pictures and also automatically tune settings to suite the type of picture to be captured.
Hardware and SoftwareUnder the hood, the Huawei P20 as the combination of a fast SoC, ample memory and storage. While this is impressive enough, the other specs don’t really match up to it. Inside, the smartphones is powered by an Octa-core Hisilicon Kirin 970 processor alongside a Mali-G72 MP12 GPU for graphics.
There is more than enough storage space for an average user despite not supporting expansion with a memory card. Boasting of about 128GB of built-in storage and a 4GB internal memory, performance is sure to be smooth. It also boots the latest Android 8.1 Oreo from the box with EMUI skin on top.
Pricing and AvailabilityThe Huawei P20 is only available in some specific online stores for about 300, 000 naira. Although your location might attract some added costs and also depends the deal in question.

Blockchains, the technology which sits underneath cryptocurrencies like Bitcoin are decentralized ledgers, held by a trustworthy source which tracks who owns what. Long after the Bitcoin hype has died down and the currency has settled at ‘normal’ levels, Blockchains are likely to remain and could underpin much of the high value transaction processing that currently only banks can perform.
Blockchains solve some of the most pressing issues associated with internet trades. Because they hold information securely on multiple computers in parallel they are hard to hack. Since they are decentralized, there are no middle men taking a cut simply for having the only machine that can conduct it. The system is far from perfect as it stands but it holds promise.
Blockchains also have facilities that current processing technology does not. The most useful of these are ‘smart contracts’.
Smart contracts can sit within BlockchainsSmart contracts are also known as ‘Self Executing Contracts.’ Blockchains are electronic in nature which offers the opportunity to build logic into them. Smart contracts are conditional terms which can be stored in many ledgers at once, as a series of rules and which will perform their task automatically.
Since, there can be multiple Blockchains, each storing different types and sorts of information, we might end up with a number of them, backed by institutions we trust (for example, the government) and combining to execute these smart contract agreements.
An example of how smart contracts might work in real lifeHere’s an example of how a smart contract might work in this sort of environment.
Imagine buying your prepaid plan at the local supermarket. You explain what you want to the cashier. He or she takes your money, hits a few keys, confirms your identity with a driver’s license and provides you your prepaid pack.
Now, imagine the same transaction in a world with multiple Blockchains. Let’s assume the US Government has released a Blockchain, which it now uses to verify the identity of citizens. This USA Blockchain is backed by the administration so it is trust worthy and holds details of your social security, birth certificate, driver’s license and, if you’re married, a marriage certificate. For the purposes of this example, you want to buy a prepaid plan, so you’re filling in a form on the AT&T website, from your mobile phone.
The smart contract in the Blockchain behind the website simply waits, as computers will do, forever, until you provide 2 things.
First, a payment of $20 (the sticker price of the prepaid plan you’re buying.) For this component of the transaction, you use a proportion of your Bitcoin balance which is held in the Blockchain to pay for that. Secondly you have to provide your ID for verification. The AT&T Blockchain contacts the government Blockchain which, since you’ve authorized it, confirms your ID for this purpose.The process hasn’t changed. However, the variables involved are now provided once to a Blockchain, issued by a trusted source which stores them securely until you need it. The process no longer includes a cashier at a supermarket. The Blockchain itself conducts the transaction, issuing the prepaid SIM pack when the conditions required are met – here, when ID is provided and payment is made. The logic for the whole thing is built in to the Blockchain. You might also notice, there was no bank involved at all.
Why do we need Smart Contracts?
Smart contracts are clear, easy to build and manage, include no middlemen so they’re cheaper and are more efficient than the delays in payment processing which the banks now currently add. They’re not pie in the sky, either. Ripple, the world’s largest Blockchain can conduct smart contract agreements and is currently valued at $20 billion.
As we’ve said, however, Blockchains in their current form are not perfect. There is a cost in electricity to conduct transactions in Blockchain and it’s rising exponentially. Some estimates suggest that it costs around $150 USD in electricity (although the price of power varies around the world, 15c / KWh is a representative cost and it currently consumes 1000 KWh to transact over a blockchain. That means that, while the prepaid example demonstrates the concept, it’s far more likely that only significant transactions like the purchase of a house will use Blockchains and smart contracts.
Blockchains hold a great deal of interest for banks, governments and other bodies which issue important, identity related information which is used again and again. They and smart contracts are likely to be the building blocks of future financial infrastructure.
