14. The blockchain is a simple yet ingenious way of passing information from A to B in a fully automated and safe manner.
15. The ticket is a block, which will be added to a ticket blockchain.
16. Decentralized blockchains are immutable, which means that the data entered is irreversible.
17. Blockchain seems complicated, and it definitely can be, but its core concept is really quite simple.
18. One key difference between a typical database and a blockchain is the way the data is structured.
19. A blockchain collects information together in groups, also known as blocks, that hold sets of information.
20. The first blockchain was conceptualized by a person (or group of people) known as Satoshi Nakamoto in 2008.
21. A blockchain database is managed autonomously using a peer-to-peer network and a distributed timestamping server.
22. The use of a blockchain removes the characteristic of infinite reproducibility from a digital asset.
23. Each block includes the cryptographic hash of the prior block in the blockchain, linking the two.

33. Few people understand what it is, but Wall Street banks, IT organizations, and consultants are buzzing about blockchain technology.
34. Blockchain technology offers a way for untrusted parties to reach consensus on a common digital history.
35. This explainer will offer simple definitions and analogies for blockchain technology.
36. It will also define Bitcoin, Bitcoin Cash, Ethereum, Litecoin, blockchain, and initial coin offerings.
37. Transactions are collected into blocks before being added to the Blockchain.
38. Of course, although the original Blockchain was intended to manage Bitcoin, other virtual currencies, such as Ether, can be used.

40. It's important to understand why Bitcoin and blockchain are not the same thing.
41. Garzik said Bitcoin was just the first demo application of what blockchain can do.
42. Because the blockchain verifies each transaction through PoW, this means no trust is required between participants in a transaction.
43. Let’s say that this 2MB block is validated by an updated node and added on to the blockchain.
44. It will try to add its block to the blockchain, but it will detect that the latest block is not valid.
45. Who paved the way for blockchains?
46. In June, Facebook announced Libra, a new blockchain that will support a digital currency.
47. But replacing government with corporations is not exactly the revolution that enthusiasts imagined blockchain would bring.
48. Other so-called “private” blockchains, like Libra, are growing in popularity.
49. Blockchain is best known as the technology underpinning the controversial Bitcoin cryptocurrency.
50. Bitcoin and by extension blockchain were created by someone using the nickname Satoshi Nakamoto.
51. Blockchain is a public ledger consisting of all transactions taken place across a peer-to-peer network.
52. In Bitcoin, the blockchain refers to all transactions that have ever been executed in the network.
53. Most tellingly, large investments in blockchain are being made.
