Blockchain is a decentralized ledger technology that records transactions and is distributed across the entire network. It is a system of recording data in a way that is nearly impossible to change. The decentralized technology is exceptionally good at eliminating third parties involved in any transaction. It provides a secure sharing environment and maintains transparency throughout the system.
The significant intrinsic features of Blockchain are:
Transparency: Blockchain maintains a transparent ecosystem throughout the network. It helps detect and identify suspicious actions/users on the distributed network.
Auditability: It is most helpful for the supply chain stakeholders, as it allows to trace back the products’ provenance and track their entire development.
Decentralization: The control of the entire network is distributed among the participating node. No single authority can claim dominion over the whole network. The consensus protocols are used to govern the network.
Immutability: Public-key cryptography ensures immutability by electronically signing every transaction on the ledger.
Anonymity: The identities of the network participants are kept anonymous during transactions to maintain the privacy and security of data.
Open-source accessibility: Blockchain provides open access to all; any authorized user can access the data available on the ledger.
What is the Blockchain development process?
Blockchain development is carried out in the following six stages:
Determine the objective
The initial step for Blockchain development is to identify the problem statement and propose a solution for it. Also, determine if you require to build the solution from scratch or some modifications and advancements would work. Analyze what features and use cases are needed for the application.
For example, a healthcare organization would need to develop a Blockchain-based application that must support health record exchange, remote patient monitoring, video conferencing, etc.
Choose a suitable Blockchain platform
Developing a Blockchain application requires thorough research, advanced technical skills and a considerable investment of time and effort. Make sure to create the Blockchain application on top of a Blockchain platform that meets your business requirements. Identify and select the right Blockchain platform for your application considering the factors like consensus mechanism, language used, etc.
For example, Ethereum is used to develop an Ethereum-based application that provides a decentralized environment with Smart contracts.
Blockchain model ideation
Once the Blockchain platform is selected, the focus must shift to drafting business requirements and brainstorming ideas. Identify the technology components that are added as off-chain or on-chain entities on the Blockchain ecosystem. Plan out the roadmap of the product to build the application within the decided deadline. Create a Blockchain model and design the conceptual workflow of the application. Besides, it is crucial to determine that the Blockchain network will be permissioned or permissionless.
Proof-of-concept means realizing a particular idea or method to demonstrate its feasibility and verify that certain concepts or theories have practical potential. In simple terms, proof-of-concept is done to represent the practical applicability of an idea. A theoretical build-up is designed and after the proposal is accepted, a prototype is prepared, which includes sketches, information architectures, designs and tested products. Once the client approves the PoC, the next step is preparing visual and technical methods.
Visual and technical designs
At this stage, the entire planning and preparation for the application development are complete. Now, start creating UIs for each software component. Create APIs that are required for integrating with user interfaces to run the application at the back-end. The application is ready after the admin consoles and user interfaces are designed.
At this stage, API integration is done for particular use cases of the application. An application is developed under multiple versions. The Pre-alpha version is the one that does not go under formal testing. After the client approves, it is moved to the Alpha stage. The developers implement white-box testing techniques at this stage. Next is the Beta version, which is released after the alpha version. Beta version is the application that has the complete feature set but might carry some unknown bugs. It is shared with a particular group of people outside the organization to test the app’s functionality. After the beta version is successfully tested, the final Release version is launched.
These are the most fundamental stages involved in the Blockchain development process. While going through the journey of Blockchain development, several complexities might arise. Make sure to hire the best and experienced Blockchain development company with a team of trained and expert developers who understand working with Blockchain technology.
Google is offering some YouTube TV subscribers a free TiVo Stream 4K or Chromecast with Google TV
Google is offering some YouTube TV subscribers a free TiVo Stream 4K or Chromecast with Google TV. It’s not satisfactory how widespread this promotion is or if it’s identified with the Roku dispute where the streaming service said it was looking for replacement devices to provide for current members.
Update: Other YouTube TV clients are getting a free Chromecast with Google TV ($49.99). This isn’t the first time Google has run this particular device promo.
To ensure our loyal YouTube TV members have a great watch experience (including the ability to watch 4K content on our optional new add-on service coming soon!), we want to offer you a free TiVo® Stream 4K device.
The streaming dongle typically costs $39.99 — however there’s at present a $10 discount. In the interim, it’s not satisfactory if TiVo will make any more Android TV-powered devices. The redemption process involves visiting the TiVo store — which is slammed with volume however will at last allow you to put in a request — and entering a unique code remembered for the present email.
During checkout, enter the unique code in the “Enter Promotion Code” box, and select “Apply Code” to ensure your discount is applied. Be sure to act fast though, as this offer is only available until July 2, 2021, or while supplies last.
The TiVo Stream 4K is powered by an Amlogic S905Y2 with 2GB of DDR4 RAM and 8GB of capacity. It upholds Dolby Vision HDR, Dolby Atmos, and 4K UHD. Google notably calls out on the latter capability in front of an add-on that allows for higher-resolution streaming. It was first declared in February, and the company says it’s “coming soon.”
This free TiVo Stream could likewise be Google’s secondary response to Roku blocking the YouTube TV application in the midst of an contract debate. Back in May, it said it was in “discussions with other partners to secure free streaming devices in case YouTube TV members face any access issues on Roku.” That said, it’s not exceptionally targeted as my account has never been related with a Roku device.
In order to be eligible, users must be active subscribers of YouTube TV and have made at least 1 valid payment. One device per household. Eligible participants will be contacted by YouTube TV by email, and must visit the promotion link provided and take action in order to claim the offer.
Our review from last year noticed how the TiVo Stream 4K provided an “excellent live TV experience,” while they were likewise fond to the “peanut” voice remote.
With the Stream 4K, TiVo clearly had one goal in mind. The brand wanted its dongle to offer a single spot for users to access not just content from TiVo, but from everywhere. That’s accomplished by the Stream+ app, preloaded on the Stream 4K.
That app is set up with a home screen that pulls in trending content, shows, and movies you’ve recently watched, live TV, recommendations, and much more.
The red PS5 controller is a other red to the red Xbox Series X controller
While the PS5’s divisive two-tone design has driven some to swap out large pieces of plastic for a more unified look, this month did in any event see Sony release some official new color options for the excellent DualSense controller. There are now “cosmic red” and “midnight black” models that may interest you more than the black and white default.
The black controller doesn’t appear to be too interesting, however as an enthusiast of red objects they requested the red one in to perceive what it looks in person. The tone is entirely strange — Sony’s marketing information puts the controller before a bright red nebula, with regards to the “cosmic red” name, and it’s a very decent match.
Essentially, it’s a little pinker than you may expect, falling somewhere between crimson, ruby, and raspberry. They think it looks great with the black trim and manages to feel appropriate for the PS5’s aesthetic.
What’s more, indeed, the little PlayStation symbols microtexture is back, however it’s still essentially difficult to see with the naked eye:
Sony is very delayed to release its first PS5 regulator shading varieties. Microsoft had dark, white, and blue options available at the dispatch of the Xbox Series X and Series S, and before long circled back to red, yellow, and camo options.
They have the red Series X regulator as well, and it’s a significantly more clear, essential shading conceal than the PS5. The thing that matters is clear when they’re close to one another.
The red and black PS5 controllers are out this week in Japan and ought to be accessible one week from now in North America, however like the PS5 itself it’ll probably be difficult to find stock. The black version expenses $69.99, while the red form is for some inexplicable reason $5 more expensive at $74.99.
Facebook Messenger adds Venmo-like QR codes for person-to-person payments in the US
This spring, Facebook affirmed it was testing Venmo-like QR codes for person-to-person payments inside its application in the U.S. Today, the organization reported those codes are launching publicly to all U.S. clients, permitting anybody to send or request money through Facebook Pay — regardless of whether they’re not Facebook friends.
The QR codes work correspondingly to those found in other payment apps, as Venmo.
The feature can be found under the “Facebook Pay” section in Messenger’s settings, gotten to by tapping on your profile icon at the top left of the screen. Here, you’ll be given your personalized QR code which looks similar as a regular QR code aside from that it features your profile icon in the middle.
Under, you’ll be shown your own Facebook Pay UR which is in the organization of “https://m.me/pay/UserName.” This can likewise be copied and sent to different clients when you’re requesting a payment.
Facebook takes note of that the codes will work between any U.S. Courier clients, and will not need a different payment app or any kind of contact section or upload process to begin.
Clients who need to have the option to send and receive money in Messenger must be in any event 18 years of age, and should have a Visa or Mastercard check card, a PayPal record or one of the upheld prepaid cards or government-issued cards, to utilize the installments highlight. They’ll likewise have to set their preferred currency to U.S. dollars in the application.
After arrangement is finished, you can pick which payment technique you need as your default and optionally protect payments behind a PIN code based on your personal preference.
The QR code is likewise accessible from the Facebook Pay section of the main Facebook application, in a carousel at the top of the screen.
Facebook Pay first launched in November 2019, as an approach to set up an installment framework that reaches out across the organization’s applications for person-to-person payments, yet in addition different highlights, similar to donations, Stars and e-commerce, in addition to other things. Despite the fact that the QR codes follow Venmo and others, the service the way things are today isn’t really an adversary to payment applications because Facebook partners with PayPal as one of the upheld payment methods.
In any case, albeit the payments experience is independent from Facebook’s cryptocurrency wallet, Novi, that is something that could maybe change later on.
The element was presented close by a couple of other Messenger updates, including a new Quick Reply bar that makes it simpler to react to a photograph or video without getting back to the main chat thread. Facebook likewise added new chat themes including one for Olivia Rodrigo fans, another for World Oceans Day, and one that promotes the new F9 film.
