The blockchain is an immutable distributed digital ledger with many use cases beyond cryptocurrencies. To understand the operation or workflow of block chaining, consider  a long series of connected data, organized into blocks that form a chain.  Each block is capable of holding a predetermined amount of data; as it is filled, it is forged into the chain and a new block is formed. whenever you need to secure any money or transfer to another user, you write a  blockchain program  and both of you send the money to the program.  The transaction is sent to a peer-to-peer network consisting of computers known as nodes. Bitcoin’s validation process is performed by miners who are rewarded for their participation in securing the network. The  nodes validates the transaction using cryptographic algorithms.  It’s that simple. All the transaction requests are associated with unique digital signatures which along with public keys are used by each node (comput...

Types of Mobile App Frameworks Native Apps A software program that is developed for use on a particular platform or device such as Android, iOS, and Windows. Apps make use of device features such as RAM, camera, GPS, and so on. Web Apps It  is  an application program that is stored on a remote server and delivered over the Internet through a browser interface .  Such as  online forms, shopping carts , word processors, spreadsheets, video and photo editing, file conversion, file scanning, and email programs . Hybrid Apps A  hybrid app  is one that is written  with HTML, CSS, and JavaScript like web apps.  Hybrid apps are deployed in a native container that uses a mobile WebView object . native code will be used to access the specific features such as accelerometer, camera, contacts… Let’s understand some of the top mobile app development frameworks, which make app development simple: React Native It is built and support...

  What exactly is blockchain? Blockchain is a system of recording information in a way that makes it difficult or impossible to change, hack, or cheat the system. Blockchain is a type of DLT(digital ledger of transactions) that is duplicated and distributed across the entire network of computer systems on the blockchain. Each block in the chain contains a number of transactions, and every time a new transaction occurs on the blockchain, a record of that transaction is added to every participant’s ledger. The transactions are recorded with an immutable cryptographic signature called a hash. It constantly and continually growing as blocks are being added to the chain, which significantly adds to the security of the ledger. If hackers wanted to corrupt a blockchain system, they would have to change every block in the chain, across all of the distributed versions of the chain.
