THE ADVANTAGES &  DISADVANTAGES OF BLOCKCHAIN TECHNOLOGY & COMPUTING





some more in depth & on paper explanation can be seen below 




Advantages of Blockchain Technology & Computing:


This section discusses the ADVANTAGES of blockchain technology  &  computing




1.Open: One of the major advantages of blockchain technology is that it is accessible to all means anyone can become a participant in the contribution to blockchain technology, one does not require any permission from anybody to join the distributed network.







2.Verifiable: Blockchain technology is used to store information in a decentralized manner so everyone can verify the correctness of the information by using zero-knowledge proof through which one party proves the correctness of data to another party without revealing anything about data.








3.Permanent: Records or information which is stored using blockchain technology is permanent means one needs not worry about losing the data because duplicate copies are stored at each local node as it is a decentralized network that has a number of trustworthy nodes.








4.Tighter Security: Blockchain uses hashing techniques to store each transaction on a block that is connected to each other so it has tighter security. It uses SHA 256 hashing technique for storing transactions.








5.Immutability: Data cannot be tampered with in blockchain technology due to its decentralized structure so any change will be reflected in all the nodes so one cannot do fraud here, hence it can be claimed that transactions are tamper-proof.








6.Transparency: It makes histories of transactions transparent everywhere all the nodes in the network have a copy of the transaction in the network. If any changes occur in the transaction it is visible to the other nodes.







7.Efficiency: Blockchain removes any third-party intervention between transactions and removes the mistake making the system efficient and faster. Settlement is made easier and smooth.






8.Cost Reduction: As blockchain needs no third man it reduces the cost for the businesses and gives trust to the other
 partner.

Disadvantages of Blockchain Technology & Computing :




This section discusses the DISADVANTAGES of blockchain technology   &  computing 


1.Scalability: It is one of the biggest drawbacks of blockchain technology as it cannot be scaled due to the fixed size of the block for storing information. The block size is 1 MB due to which it can hold only a couple of transactions on a single block.



2.Energy Consuming: For verifying any transaction a lot of energy is used so it becomes a problem according to the survey it is considered that 0.3 percent of the world’s electricity had been used by 2018 in the verification of transactions done using blockchain technology.





3.Time-consuming:To add the next block in the chain miners need to compute nonce values many times so this is a time-consuming process and needs to be speed up to be used for industrial purposes.


4.Legal Formalities: In some countries, the use of blockchain technology applications is banned like cryptocurrency due to some environmental issues they are not promoting to use blockchain technology in the commercial sector.



5.Storage: Blockchain databases are stored on all the nodes of the network creates an issue with the storage, increasing number of transactions will require more storage.
Regulations: Blockchain faces challenges with some financial institution. Other aspects of technology will be required in order to adopt blockchain in wider aspect.

INTO THE WORLD OF DE-FI! SERIES NAME:- "LEVEL UP" BY = CHITEKI KUN! -(N.S.R) DE-FI MEANS "DECENTRALIZED FINANCE"!   POD-3............................ let us see some ADVANTAGES & DISADVANTAGES of   CRYPTO-MINING let's jump together folk's Downsides of Mining :- The risks of mining are often financial and regulatory. As aforementioned, Bitcoin mining, and mining in general, is a financial risk because one could go through all the effort of purchasing hundreds or thousands of dollars worth of mining equipment only to have no return on their investment. That said, this risk can be mitigated by joining mining pools. If you are considering mining and live in an area where it is prohibited, you should reconsider. It may also be a good idea to research your country's regulation and overall sentiment toward cryptocurrency before investing in mining equipment. One additional potential risk from the growth of Bitcoin mining (and other  systems as well) is t

  INTO THE WORLD OF  " QUANTUM COMPUTER  & COMPUTING " SERIES NAME: - " LEVEL UP " BY = CHITEKI KUN!-(N.S.R) WHAT IS A QUANTUM COMPUTER:- Quantum computers are machines that use the properties of QUANTUM PHYSICS to store data and perform computations. This can be extremely advantageous for certain tasks where they could vastly outperform .Supercomputers,Classical computers, which include smartphones and laptops, encode information in binary “bits” that can either be 0s or 1s. In a quantum computer, the basic unit of memory is a (quantum bit) or QUBIT. WHAT IS QUBIT :- In quantum computing, a qubit or quantum bit is a basic unit of quantum information—the quantum version of the classic binary bit physically realized with a two-state device. A qubit is a two-state quantum-mechanical system, one of the simplest quantum systems displaying the peculiarity of quantum mechanics. Qubits are made using physical systems, such as the spin of an electron or the orientation
