How Blockchain Manages Transactions - Quick Recap

  • Blockchain stores each transaction in Blocks. No one can tamper or change the details. 
  • The people who are making a transaction in Blockchain world they both have same copies. 
  • No possibility of changing these records by parties involved. So it is robust.

  4. Stores all records permanently.
  5. One cannot edit or manipulate the data.
  6. Hacking is not possible.  In Blockchain one cannot hack the data. Since it is distributed.
  7. The centralized processing is slower. Whereas Blockchain is much faster. Verification and completing a transaction is much faster.
  8. The centralized system is expensive. Each server in the network charges some amount as processing fee. In Blockchain, you can eliminate intermediaries.
  9. The Centralized databases are expensive to carry transactions of low value. The fee to pay intermediaries is huge.
  10. Data in Blockchain cannot be edited. In the case of Centralized databases, the Banks or Private Organizations can edit it.
  11. Maintenance of Blockchain is cheaper.

Key Disadvantages of Blockchain

15 awesome Java Interview Questions to know

Image
Java interview is one of the tough interviews for developers coming from other technologies. So I have given very basic interview questions they asked. Really awesome to know these questions.


1. What is JVM? Why is Java called the ‘Platform Independent Programming Language’?
JVM, or the Java Virtual Machine, is an interpreter that accepts ‘Bytecode’ and executes it.
Java has been termed as a ‘Platform Independent Language’ as it primarily works on the notion of ‘compile once, run everywhere’. Here’s a sequential step establishing the Platform independence feature in Java: The Java Compiler outputs Non-Executable Codes called ‘Bytecode’. Bytecode is a highly optimized set of a computer instruction which could be executed by the Java Virtual Machine (JVM). The translation into Bytecode makes a program easier to be executed across a wide range of platforms since all we need is a JVM designed for that particular platform. JVMs for various platforms might vary in configuration, those they w…
