 Virtually anything of value can be tracked and
traded on a blockchain network, reducing risk

What is Blockchain ?  Blockchain is a shared, immutable ledger that facilitates the process of recording transactions and tracking assets in a business network.  An asset can be tangible (a house, car, cash, land) or intangible (intellectual property, patents, copyrights, branding).  Virtually anything of value can be tracked and traded on a blockchain network, reducing risk and cutting costs for all involved. (A ledger is a book or collection of accounts in which account transactions are recorded.)
  • 6. Record the transaction Gain consensus Link the blocks Share the ledger STEPS INVOLVED HOW IT WORKS ?
  • 7. Step 1 – Record the transaction A blockchain transaction shows the movement of physical or digital assets from one party to another in the blockchain network. It is recorded as a data block and can include details like these: • Who was involved in the transaction? • What happened during the transaction? • When did the transaction occur?
  • 8. Step 2 – Gain consensus • Most participants on the distributed blockchain network must agree that the recorded transaction is valid. • Depending on the type of network, rules of agreement can vary but are typically established at the start of the network.
  • 9. STEP 3 – LINK THE BLOCKS  Once the participants have reached a consensus, transactions on the blockchain are written into blocks equivalent to the pages of a ledger book.  Along with the transactions, a cryptographic hash is also appended to the new block. The hash acts as a chain that links the blocks together.  This is like stacking wooden blocks to make a tower.
  • 10. Step 4 – Share the ledger •The system distributes the latest copy of the central ledger to all participants
  • 13. It is used in Cryptocurrency (Bitcoin, ethereum, altcoin, litecoin). Used in the smart contract (It is handle autonomously the fulfillment of a contract without needing a third party). It is also used in digital voting. Government registration of land. Transportation and supply chain management. APPLICATION OF BLOCKCHAIN:
  • 14. 1. Bitcoin The primary application of Blockchain is in Cryptocurrencies like Bitcoin. Bitcoin is a decentralized digital currency introduced by Santoshi Nakamoto. 2. Banking Nowadays, Blockchain is also replacing the existing, or we can say overtaking the current Banking system. Because of the Blockchain, the hacking of accounts will become impossible.
  • 15. 3. Healthcare Healthcare is also a domain where Blockchain technology has been used for storing the details of the patients. This technology ensures that anyone accessing this Blockchain can access patients’ data. 4.Voting Blockchain can be used in the next election or Voting because of its unchanging revolutionary nature. Voting will become more secure and fail-proof with the help of Blockchain.
  • 17. CONCLUSION:- • Blockchain is an emerging technology and its use at present is limited only to the crypto currency. This technology is also said to be useful in different sectors in the coming future. It is being tested for the same in different sectors in several countries of the world. It is brought into use in the banking and commerce sectors in different countries. • This technology is becoming popular at a very fast pace and there are many fields where it can bring revolutionary changes.
