Blockchain applications are growing in the financial world. Security is the main motto behind blockchain applications. You cannot tamper a record once created. What is a platform   A platform is a place where you can develop applications. Top Blockchain Cloud Platforms The development needs to create a project and deploy it into production. So that the real use can feel by users at their end. Ok... Let us come to three popular cloud platforms that are highly used in Blockchain applications: HyperLedger IBM BlueMix Microsoft Azure #1. HyperLedger The Hyperledger project is led by Executive Director Brian Behlendorf, who has decades of experience dating back to the original Linux Foundation and Apache Foundation, as well as being a CTO of the World Economic Forum. So it's not surprising that Hyperledger has been well received. You can learn hyper Ledger here. Many of the top business and industry leaders have joined the project, including Accenture, Cisco, Fujitsu

Bitcoin was the first project developed by using blockchain. My post is to share Blockchain keywords by using an example of Bitcoin. Let us ready... Blockchain is new technology. Understanding its principles makes you helpful to apply in your projects.  Initially, the purpose of  Blockchain development was to carry mining. In general, mining means search and find value. Usually, mining processes are two types. Those are data mining and bitcoin mining . Blockchain Glossary Blockchain - only blocks involved. The data which was finalized stored in blocks. Bitcoin Ledger - It is a public ledger Ledger or Blockchain - The chain of blocks Functions of Blockchain - It validates each transaction, Keeps track, and verifies ownership Double Spending- It prevents duplicating the Cryptocurrency for using next time. Consensus mechanism - It is also called PoW (proof of work). This mechanism avoids double-spending Group of Transactions - When a new group of transactions created, t

Here are the disadvantages of Blockchain. Below, you will find the list of these. Blockchain Disadvantages Lack of privacy Loss of personal responsibility Loss of jobs Reintermediation 1. Lack of Privacy Public blockchains do not hide any of their data. Instead, everyone can read the complete history of transactions. This level of transparency is frightening for those who want to protect their privacy. These concerns are understandable when considering the level at which personal data are already collected and utilized by large corporations or intelligence agencies. 2. Loss of Responsibility Loss of personal responsibility is often considered a consequence of disintermediation. Intermediaries not only bring different parties of a contract together but may also provide guarantees. They offer reconciliation in cases when transactions do not work out as intended, and they are also obliged to take responsibility for their actions. The shift from trust in people and human organizations to

Robotic process  automation  is an upcoming IT skill. Three tools are popular. It is difficult to learn all three tools. So, learn anyone's tool to start your career in automation. To get a job in this line, I found in my research that some programming skills and Hand-on training on any one of the tools are required. Also, try to know  the differences between popular RPA tools . Skills Companies Looking in Automation Engineers All big companies looking for candidates having experience in Automation Anywhere , Blue Prism, and UIPath. It is not possible to learn all tools. Learn anyone's tool and do practice well. Ok. You may ask a question about how to do it. Join in a good training institute and learn one tool.  Take online classes to learn faster.

Robotic process automation is a grown-up area. Many IT developers across the board started up-skill in this popular area. This post is useful for Software developers who are interested in RPA (Robotic Process Automation). In my previous post , I have shared twelve RPA tools. Out of those, three tools are the most popular. Those are Automation Anywhere, BluePrism, and Uipath. This post covers differences in these tools. Blue Prism Blue Prism has taken a simple concept, replicating user activity on the desktop, and made it enterprise strength. The technology is scalable, secure, resilient, and flexible. It is has a comprehensive methodology, operational framework, and provided as packaged software. The technology is developed and deployed within a corridor of IT governance. It has sophisticated error handling and process modeling capabilities to ensure it can perform at scale within demanding, highly sophisticated operating environments. The combination of SOA/BPMS and Blue Prism pl

SBI is now pressing ahead with its first implementation of the decentralized technology by using an enterprise blockchain solution for managing its Know Your Customer (KYC) system, via a new partnership with Intel that sees the technology giant become the consortium’s official technology advisor. What is KYC Know your customer means all banks update information about their customers. Customer details are Phone number, Aadhar Card, PAN, Home Address, etc. These details are mandatory to update once in six months. Blockchain Platform to Use in KYC is Hyperledger Sawtooth The enterprise blockchain will run on Hyperledger Sawtooth, a modular platform for developing and deploying blockchains, developed by Intel – a member of the open-source Linux Foundation-led Hyperledger project. The blockchain will also be supplemented by Intel Software Guard Extensions (SGX) to boost the blockchain’s privacy, security, and scalability. The blockchain solution will be delivered by Primechain, an Indian bl
