- 4. What’s Blockchain? Blockchain Technology was originally developed as part of the digital currency Bitcoin. But the two are not the same. Blockchain can support a wide range of applications, It’s already being used for peer to peer payment services, supply chain tracking and more
- 5. A Digital Record A Blockchain is a record of transactions, like a traditional ledger. Transactions can be any write operation, money transfer from a person to another, a purchase at a supermarket
- 6. Distributed Today, transactions are verified by a central authority—like a government or a credit card clearinghouse. Blockchain applications could replace these centralized systems with decentralized ones, where verification comes from the consensus of multiple users.
- 7. Secure Blockchain is designed to store information in a way that makes it virtually impossible to add, remove or change data without being detected by other users.
- 8. How Does It Work? 02
- 9. How Does It Work? ● Gather and order data into blocks ● Chain them together securely using cryptography. A blockchain needs to do two things
- 10. Start With Simple Transaction Let’s assume A sells his car to B Transaction_02 Address 0x0c77c52b355fd6DA8cAfd80D16004807a3bB3EB9 Amount 10k BTC Size 255 Bytes Block Block # 4319 Received 11:46 Sat 9/20/2019
- 11. Start With Simple Transaction The transaction is recorded and shared between network nodes

- 15. Securing The Chain Hash The key of the blockchain security is something called hash.It's a bit of cryptographic math that makes the links between blocks virtually unbreakable. Hash Function A hash function takes the information in each block and uses it to create the hash—a unique string of characters. Hello World! 7f83b1657ff1fc53b92dc1 8148a1d65dfc2d4b1fa3d 677284addd200126d9069
- 16. Securing The Chain Lock It Down! The hash from one block is added to the data in the next block, So when the next block goes through the hash function, a trace of it is woven into the new hash.
- 17. Securing The Chain Lock It Down! Block_00 (Genesis Block) Data: { Transactions:{ } Pervious_Hash:0 } Hash:7f83b1657ff1fc53b92dc18148a1d6 5dfc2d4b1fa3d677284addd200126d9069 Block_01 (Genesis Block) Data: { Transactions:{ } Pervious_Hash:7f83b1657ff1fc53b 92dc18148a1d65dfc2d4b1fa3d677284addd2 00126d9069 } Hash:f4e5f3a4579ce87db8537bbb0621e 64fc14e39cde263c275ef201e5712dfdba0
- 18. Securing The Chain Lock It Down! So if there's any attempt to alter a previously created block, the hash that's encoded in the next block won't match up anymore. This mismatch will continue through all subsequent blocks denoting an alteration in the chain.
- 19. Securing The Chain Distribute The Blockchain Since all participants have a copy of the entire blockchain, they can detect any tampering. So when the hashes match up across the chain, all parties know that they can trust their records.
- 22. Bitcoin Blockchain Bitcoin is a cryptocurrency, a form of electronic cash. It is a decentralized digital currency without a central bank or single administrator that can be sent from user to user on the peer-to-peer bitcoin blockchain network without the need for intermediaries.
- 23. Ethereum Blockchain Ethereum is a global, open-source platform for decentralized applications. On Ethereum, you can write code that controls digital value, runs exactly as programmed, and is accessible anywhere in the world.
- 24. Libra Blockchain A simple global currency and financial infrastructure that empowers billions of people. Reinvent money. Transform the global economy. So people everywhere can live better lives.
- 26. Blockchain In Action The technology is still new, but its potential is enormous. Here are some examples of how blockchain could hypothetically transform everyday transactions. Because blockchains establish trust, they provide a simple, paperless way to establish ownership of money, information and objects—like Digital ID.
- 27. Digital ID Blockchain can track more than commercial transactions; it can also hold and protect sensitive information. For example, ID papers have traditionally been issued and monitored by governments. But digitally-issued identification via blockchain could be a more secure mechanism.
- 28. ID at Your Fingertips An international ID blockchain, accessible anywhere in the world, allows people to prove their identity, connect with family members and even receive money without a bank account.
- 29. ID at Your Fingertips The fingerprint is digitized and the information is added to the blockchain, along with her name and other key information. Name John Doe DOB 1996/11/11 Location NEW YORK CIty Marital Status Single
- 30. Beyond The First Steps 05
- 31. Are Businesses Ready for Blockchain? For businesses, blockchain could be a radical departure from manual processes. And new costs and risks come with any new technology. Companies might be reluctant to make that leap. 2.Global Companies Start Adopting Blockchain 4.Majority Of Companies Have Blockchain Projects In Production 5.Widespread Adoption Of Blockchain 3.Early Adopters Begin To Benefit 1.Companies Piloting Uses Of Blockchain Technology
- 32. Are Businesses Ready for Blockchain? Can the technology handle the high volume required for mainstream commercial work? Even the most established blockchain—the one used for Bitcoin—can only process five to eight transactions a second.
- 33. The Takeaway 06
- 34. Blockchain could be a revolution in the way everyone—businesses, governments, organizations and individuals—work together. It provides a simple, secure way to establish trust for virtually any kind of transaction, helping simplify the movement of money, products or sensitive information worldwide.
