Blockchain Technology – Uses, Benefits, and Top Companies

Blockchain technology, the core framework behind cryptocurrencies like Bitcoin, is gaining popularity. As per estimates, there are 170 million blockchain wallets worldwide and counting. Blockchain technology is expected to see an annual growth of 56.3%, which should increase its value to over $163 billion by 2029. However, these are only projections, and there is a lot for one to understand before trying out the features of such a complex technology.

Understanding blockchain
A blockchain is a distributed database that maintains a growing list of records, called blocks, linked together using cryptography. Each digital block contains a timestamp, transaction data, and a cryptographic hash of the previous block. In other words, the blockchain is a decentralized public ledger. Since the same data is duplicated across multiple computers in real-time, the records are nearly impossible to alter without changing them on another system.

Uses of the technology
The implementation of blockchain stretches far beyond recording and storing cryptocurrency transactions. Developers are gradually testing the technology’s uses across other avenues. For instance, blockchain can help monitor business supply chains in real-time to eliminate errors and check the quality of products. It can also help organizations process payments and make money transfers within minutes. Further, the technology can allow people to protect their digital identities, letting them pick who has access. Similarly, business data can be securely shared and stored. A decentralized database ensures various artists, open-source developers, and creators get the required copyright and royalty protection. In addition, blockchain helps wirelessly identify and manage multiple devices, such as smartphones, cars, and other electronics. Even healthcare professionals can use the technology to manage electronic health records and clinical trial data in compliance with existing guidelines.

Benefits
Completing transactions with blockchain helps save time. The technology is also more secure from potential tempering, fraudulent account creations, and scams, so transactions require minimal oversight. Further, people can exchange items of value directly, saving money.

Top blockchain development companies
With cryptocurrencies gaining traction, several businesses have started exploring and developing the technology. A few top companies are:

LeewayHertz
This promising blockchain development company specializes in the internet of things (IoT), artificial intelligence (AI), cloud services, and virtual reality. LeewayHertz is also famous for providing end-to-end blockchain solutions. These include blockchain development, blockchain consulting for user experience and design, deployment and upgrades, and maintenance solutions.

ConsenSys
ConsenSys is another top development company for Ethereum. They build developer tools, blockchain-based applications, and solutions for enterprises on the Ethereum blockchain. Moreover, ConsenSys offers blockchain-based solutions for institutional capital markets, payments, asset management, decentralized finance, and global trade and commerce. Some of their products with millions of users include Quorum, Codefi, Diligence, Truffle, and Metamask.

MLG Blockchain
The developer caters to enterprises dealing with capital management, ITO liquidation, and drawing up SAFT investment agreements. MLG Blockchain is experienced in developing blockchain applications on platforms like EOS, Ethereum, Hyperledger, and Neo. These applications can be used immediately after integration with business software.

Coinbase
Coinbase is well-known for providing financial infrastructure globally with the help of its transaction services and curated technology designed for the cryptocurrency economy. The company offers institutions a deep liquidity pool, enabling them to transact in crypto assets. They allow crypto users to invest, save, spend, earn and utilize cryptocurrencies. Coinbase also enables crypto-ecosystem developers to create crypto-based applications while securely accepting crypto assets as payment.

Innovecs
Innovecs specializes in blockchain application development, distributed money transfer solutions, enterprise cryptocurrency platforms, loyalty programs, and distributed document management. These services are offered to various industries, including healthcare, e-commerce, and retail. Work across such avenues has enabled the company to understand blockchain technology better and improve its services.

Requirements for becoming a blockchain developer
Many individuals aspire to develop a custom blockchain. If you are also interested in learning and creating such technology, you should:

Learn a high-level programming language
To become a blockchain developer, one must be proficient in at least one high-level programming language. A few popular examples are C#, Java, JavaScript, Python, C++, Golang, Ruby, and Solidity.

Understand blockchain technology well
Blockchain developers must understand how a decentralized network works. They should also be able to answer questions about multiple blockchains, as each blockchain application is different. To start, one can study core blockchain development concepts, such as security for peer-to-peer networks, consensus algorithms, and distributed ledger technology.

Study cryptography and security principles
Since blockchain technology is based on cryptography, one must understand the concept and its security principles. Cryptography is a method of keeping information on a blockchain secure without requiring a third party to manage and handle its security.

Get experience with peer-to-peer networking
The blockchain network is decentralized, so there is no central control or point of failure. A custom blockchain developer or someone who works for a blockchain company must be well-versed in such peer-to-peer networking and distributed systems to ensure the blockchain functions smoothly.

Learn about smart digital contracts
Smart contracts are an essential element of blockchain technology. They contain the terms and conditions between two or more parties in the agreement. Once this contract goes live, it runs autonomously without the involvement of a third party. A developer will need to write and execute smart contracts to ensure the blockchain functions without hiccups.

Gain knowledge about algorithms
A blockchain algorithm is used to execute tasks and solve problems. A few popular algorithms in the industry include Delegated Proof of Stake (DPoS), Proof of Stake (PoS), and Proof of Work (PoW). As a blockchain developer, one should be able to write algorithms for purposes like balance confirmation and digital signature verification. They should also be able to validate and process new transactions written to the blockchain, implement consensus protocols, and write applications that utilize stored information on a blockchain.

3 Reasons to Choose the Google Pixel 6 Series

Google launched its popular smartphone series in October 2021: the Google Pixel 6 and the Google Pixel 6 Pro. Many reviewers believe it is the most significant update since the launch of Pixel. These phones compete with premium offerings from competitors, like the iPhone 13 series and the Samsung Galaxy S21 series. But does the latest smartphone live up to the hype? A look at the features can help you decide. Enhanced design At first glance, you will notice Google's new design approach on both the Pixel 6 and the Pixel 6 Pro. They seem to have discontinued the plastic back with a square camera array at the top corner. Instead, the devices now have a glass back with a horizontal camera bar that holds the lenses and flashlight. The choice of colors varies depending on the model you pick. While the Pixel 6 is available in Stormy Black, Kinda Coral, and Sorta Seafoam, the advanced 6 Pro features in Stormy Black, Sorta Sunny, and Cloudy White. Better specifications Leading carriers like Verizon offer 5G connectivity for both the Pixel 6 and the 6 Pro, making 5G the default network choice. Apart from that, here are the individual features and specifications that make these devices attractive: Google Pixel 6 The Google Pixel 6 5G smartphone is beautifully designed. At 6.4 inches, the display is neither too big nor too small. It is larger than the latest iPhone 13 but less than OnePlus 9. The FHD+ OLED screen with an adaptive refresh rate of 90 Hz is great for smooth scrolling and gameplay. The best advantage is that the refresh rate can be reduced to 60 Hz to preserve the battery. At the back, the Pixel 6 has an upgraded rear camera array. The primary wide-angle camera is now 50 MP, up from a mere 12 MP. The front camera is 8 MP. Under the hood, it packs 8 GB of RAM, the Google Tensor CPU, and the Titan M2™ security coprocessor. The performance of the Tensor chip is said to be 80 percent faster than any other previously used in a Pixel phone. It may not be a tall claim, but reviewers and first-time users have not complained of sluggishness when multitasking. The new animations by Android 12 are also fluid and do not stutter. The phone has several new software tricks integrated for both everyday use and enhanced photos. One such feature in both Pixel phones is the Magic Eraser that you can use to remove unwanted items in a photo automatically or by simply circling the object. While the edits may appear obvious, they are certainly handy in excluding unnecessary elements. The Pixel 6 comes with storage options of 128 GB and 256 GB, allowing you to store your favorite photos and download games and apps without worrying. The battery capacity is 4614 mAh. Google Pixel 6 Pro If you are a Pixel fan but want more than what the above Google Pixel 6 5G smartphone offers, the Pro version may be suitable. It has a larger screen at 6.7 inches with a QHD+ OLED display. While the Pixel 6 has a refresh rate of up to 90 Hz, this one offers up to 120 Hz for an even smoother scrolling and gaming experience. You can reduce the refresh rate to 90 Hz to preserve battery life. The device has an additional 48 MP telephoto lens in its rear camera array, and the front camera is 11.1 MP. The quality of photos in the latest Pixel series has improved. Portrait pictures can differentiate between the foreground and background more consistently than its predecessors. Also, the pictures are more life-like, an approach that leading brands take with their flagship cellphones. The Pixel 6 Pro has 12 GB of RAM powered by the Titan M2™ security coprocessor. If you are looking for more significant storage, there is a 512 GB option, unlike the Pixel 6, which only offers 128 GB and 256 GB. The estimated battery size is 5003 mAh. Improved operating system The latest Android update makes Google Pixel 6 5G a smart cellphone. Android 12 feels like the OS has moved a step forward. You not only receive a long and attractive list of new features, but the design approach is also welcoming. Some fresh features make it fun to use your phone. For instance, an animation makes the screen gradually fade and turn into a power button when you lock your phone or put it to sleep. A similar effect is applied when closing an app and returning to the home screen. The new OS also brings many new privacy features. For instance, the device sends notifications or prompts when an app is accessing your phone's camera or microphone. In addition, a privacy dashboard shows how frequently these apps are using personal information and suggests ways to secure your account. You can also control how you wish to share your location information with an app. If you are interested in purchasing these phones, they are available on the official website and in leading gadget stores. Do not forget to look for offers on Google Pixel 6 5G smartphones. Some retailers allow you to trade in an old phone for credit. All you need to do is bring the used phone during purchase. Then based on its condition, the store offers a discount on the new phone. Apart from this, network carriers offer beneficial deals and financing options.

Top Features That Make Dell XPS 15 a Great Laptop

Dell’s XPS 15 laptops have become a favorite among buyers. At first glance, it is not easy to understand how such a light, delicate laptop packs such an impressive performance. But, with just one use, you can experience its superior functioning and handy features, which also justify the gadget’s price tag. If you want a new Dell laptop, either a previous-generation model or the latest one, then the XPS 15 is the best option.  Configuration and pricing The base model offers features like 8 GB RAM, Intel Core i5-12500H processor, 512GB SSD, and UHD graphics and comes at a price of $1,449, which is also Dell XPS 15’s lowest price yet. However, if you do not wish to forego the other premium offerings, you can opt for the high-end Dell XPS 15 with 64GB RAM, Intel Core i9-12900HK CPU, and 4TB SSD, and it is priced at $3,899. Based on the configuration and display quality you choose, expect to shell out anywhere between $1,400 and $4,000 on a new Dell XPS 15. Design Dell’s lightweight XPS 15 is a perfect choice for people looking for an elegant, fast, and performance-driven gadget. When looking at Dell XPS 15 options and comparing older gadgets in the series, you will find a few unique features in the latest model. Here are some of the key features of the new laptop: Equipped with an aluminum body, this sleek laptop is available in two color options: a Platinum silver exterior paired with a black interior and a Frost exterior with Artic white interior. The laptop design has been revamped and now has a gigantic touchpad that takes up almost half the deck space. On either side of the keyboard, upward-firing tweeters are paired with woofers to deliver excellent-quality audio. Dell first introduced the top speakers in 2020, and it looks like this audio setup is here to stay, like the computer’s thin-bezel design. This is one of the few laptops that have an edge-to-edge display. It sports a narrow border around its 15.6-inch screen and comes with an IR camera. A key safety feature here is a fingerprint sensor for easy and secure login. While this can be considered an ultra-thin laptop, it is not extremely light. The solid aluminum body, although premium, limits the portability of the laptop. The dimensions of this 4.3-pound gadget are 13.6x9.1x0.7 inches. However, rest assured that you are trading in the easy portability of XPS 15 for a superior quality body and build. Additionally, you will not notice any hairline gaps or keyboard flex with this laptop. Ports The left side of the laptop sports a lock slot. Adjacent to this slot is a set of two Thunderbolt 4 ports that can be used for transferring data, charging, and connecting other peripheral devices. On the right, you get a headphone jack, a full SD card slot, and a USB Type-C port. Surprisingly, Dell XPS 15 is probably one of the few laptops that still come with a full SD card slot. This feature is a boon for videographers and photographers. That said, when you compare the gadget with a few competitor laptops, the SD card slot here replaces an additional USB-C port. Another key convenience that buyers might miss is a USB-A port. However, Dell does try to make up for its absence by offering adapters that help convert a USB Type C port to a USB Type A. Display As people are only just beginning to get used to the color vibrancy and reproduction rate of an OLED screen on televisions, Dell has already managed to offer the technology in its laptops. The details in this design make you pay attention to every that pops up on your laptop screen, and you will be able to notice details that you have otherwise missed on other displays. The laptop can truly transport you to a different place as soon as you play a video on it. Not just that, you can also try playing a 4K definition video. You can play with colors and contrast settings and choose from multiple presets in the Dell CinemaColor application. It even overcomes a common issue people have with OLED screens, i.e., their brightness. The brightness on the Dell XPS 15 OLED display is as great as on some other premium laptops, if not better. This makes it easier to look at the screen in bright places. Additionally, the touchscreen is extremely easy to operate. Touchpad and keyboard The laptop comes with a massive touchpad with a glass-coated surface that makes it satin-smooth. The touchpad is smart enough not to react to accidental swipes. It is fast to pick up gestures like two and three-finger swipes and pinch-to-zoom functions. As for the keyboard, it is big enough to help you avoid typos. However, people with small hands might find it difficult to reach a few keys like backspace and ESC without lifting their hands. That said, you do not get exceptional technology in the keyboard, which can seem a little underwhelming considering all the other attractive features of the laptop. Performance It may look like a slim and delicate machine, but that does not reflect in the gadget’s performance. You can think of the computer as a person with invisible muscle strength. So, based on the configuration you choose, you can get extremely powerful performance with this ultra-thin laptop. This will let you run heavy apps and games with speed and precision and without any glitches.  So keep an eye out for discounts during the Dell XPS 15 sale on the brand’s official website and get the best deal on your brand-new gadget.

Essential Points and Services to Consider for Gutter Protection

Renovation and upgrades are not just limited to the aesthetic changes around the house. It also includes the necessary repairs and maintenance to ensure there are no unnoticed damages that could worsen with time. Rain gutters collect all the water and provide a proper outlet flow to prevent leaks during a heavy pour. And gutter protection systems ensure these drainage outlets operate efficiently. Here are essential points to consider before installing these systems. Gutter guards function as a primary filter Protective covers prevent leaves, mud, sticks, and even smaller rodents or pests from washing into the small opening designed for water collection. This helps lower the cost of maintenance significantly, as you do not have to frequently clean these outlets. Most guards have a crisscross mesh pattern that allows only liquids to flow into the drainage system. With protective covers installed, you spend no more than a couple of hundred dollars to have the entire system serviced twice a year. Long-term utility benefits When water flows freely within the drainage system, it reduces the risk of pooling or overflowing and ultimately leaking. Water pooling, if left unchecked, can also damage the structural integrity of the home. Moreover, dirty, backed-up rainwater becomes a breeding ground for mosquitoes and other parasites, increasing the risk of infection.
