Blockchain four possible disadvantages really you need to know

There are some possible disadvantages. But, these are just a list sof ar. You already came to know about complete information on Blockchain in my previous post. Here the details are as follows. The disadvantages are as follows:
  • Lack of privacy
  • Loss of personal responsibility
  • Loss of jobs
  • Reintermediation


Lack of Privacy

Public blockchains do not hide any of their data. Instead, everyone is able to read the whole history of transactions. This level of transparency is frightening for those who want to protect their privacy. These concerns are understandable when taking into account the level at which personal data are already collected and utilized by large corporations or intelligence agencies.

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 toward trust in protocols and technology may lead to a loss of personal service and personal responsibility.

Loss of Jobs
Automation and standardization have not only shaped the process and the costs of producing goods but also caused friction in the labor market. Many players in the financial industry such as banks, brokers, custodians, money-transfer agencies, and notaries are directly tied to their roles as intermediaries. Many jobs in these institutions could be at risk when a huge portion of financial transactions are processed in an automated fashion through the blockchain.

Reintermediation
The complexity and its open legal status may discourage individual people as well as organizations from using the blockchain, which can cause an effect that counteracts disintermediation. Instead of using the blockchain in order to interact with contracting parties directly, people may decide to utilize services offered by intermediaries, which in turn use the blockchain. This effect could seriously slow down the adoption of the blockchain and counteract some of its major accomplishments.

Data science Secrets Simple Project Useful for Practice

I want to share with you how to use Python for your Data science or analytics Projects. Many programmers struggle to learn Data science because they do not know where to start. You can get hands on if you start with a mini project.

I have used Ubuntu Operating System for this project Skills You Must Need to become a Data Scientist You need dual skills - Learning and Apply knowledge. In Data science you need to learn and apply your knowledge. After study engineering, any person getsB Tech or M Tech Degree. You can become a real engineer if you apply engineering principles. So Data science also the same.

Data Visualization in Python is my simple project Importance of Data Data is the precious resource in resolving Machine Learning and Data Science Problems. Define first what is your problem.

Top Solidity Interview Questions for Sure Success

Solidity is the prime language to write logic for smart contracts in Ethereum blockchain. These are selected interview questions refresh before you take any interview.

Interview Questions on Solidity1. What is Solidity?

A) Solidity is the main language that you can use to write programs in Blockchain, such as smart contracts.

2. Where the Solidity programs run in Ethereum?

A). Those will run in EVM. You can also call it as Ethereum virtual Machine.

3. What kind of logic a Smart Contract can contain?

A contract in the sense of Solidity is a collection of code (its functions) and data (itsstate) that resides at a specific address on the Ethereum blockchain

4). Can the source code of smart contract accessible to the outside world? 

A). No, it is not possible to access source code to the network. Also, there is a limited access to one smart contract logic to the other smart contract logic. Eve, file system and other processes cannot access the source code.

Actually the code is sand boxed an…

Automation developer these are top Skills you need to learn

Robotic process automation is an upcoming IT skill. Three tools are popular. It is difficult to learn all three tool. So, learn anyone 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 is 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 tool and do practice well.

Ok.

You may ask a question about how to do it. Join in good training institute and learn one tool.  Take online classes to learn faster.

8 Popular Encryption methods real Usage

Encryption works as it replaces original data with some special characters and stores the data. You need a private key to decrypt the data. Else it is not possible to understand encrypted data even for hackers.

Private keys are two types. Sender uses one private key and receiver uses one other private key.
I have given in this post about 8 encryption methods.

 Different Encryption Methods Classic CipherRandom Key GenerationRSA TokenHash FunctionsMac value - Message Authentication codeKey HashTLS ProtocolAuthenticated Cipher  1. Classic Cipher The best example is this kind of algorithm was used in world war -II communication machines. 2. Random Key Generations One kind of security. They use an algorithm that sends random numbers. People use that number as a password.
3. RSA Token Every 60 seconds a token is generated. Mostly people use for financial applications. An extra identity mechanism along with user id and password. 4. Hash Functions It assigns a hash va…

Three popular RPA tools functional differences

Robotic process automation is growing area and many IT developers across the board started up-skill in this popular area. I have written this post for the benefit of Software developers who are interested in RPA also called Robotic Process Automation.


In my previous post, I have described that total 12 tools are available in the market. Out of those 3 tools are most popular. Those are Automation anywhere, BluePrism and Uipath. Many programmers asked what are the differences between these tools. I have given differences of all these three RPA tools.

BluePrism 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 and is supported by a comprehensive methodology, operational framework and provided as packaged software.The technology is developed and deployed within a “corridor of IT governance” and has sophisticated error handling and process modelling capabilities to ens…
