2 Demystifying Blockchain & its Impact on the Supply Chain Louise Wiggett August 2018

3 Blockchain The Start : 1991 The first work on a cryptographically secured chain of blocks was described in 1991 by Stuart Haber and W. Scott Stornetta They wanted to implement a system where documents' timestamps could not be tampered with or backdated In 1992, Bayer, Haber and Stornetta incorporated Merkle Trees to the design, which improved its efficiency by allowing several documents to be collected into one block 3

4 Blockchain Progress : 2008 The first public blockchain was conceptualized by a person (or group of people) known as Satoshi Nakamoto in 2008 It was implemented the following year by Nakamoto as a core component of the cryptocurrency bitcoin, serving as the public ledger for all transactions on the network However Blockchain is not Bitcoin two concepts that are often confused 4

5 Blockchain Progress : 2016 The words block and chain were used separately in Satoshi Nakamoto's original paper, but were eventually popularized as a single word, blockchain, by 2016 The term blockchain 2.0 refers to new applications of the distributed blockchain database, first emerging in 2014 IBM opened a blockchain innovation research center in Singapore in July 2016 A working group for the World Economic Forum met in November 2016 to discuss the development of governance models related to blockchain 5

6 Blockchain Explosion : 2018 IBM offers a cloud blockchain service based on the open source Hyperledger Fabric project On May 8, 2018 Facebook confirmed that it is opening a new blockchain group which will be headed by David Marcus who previously was in charge of Messenger. According to The Verge, Facebook is planning to launch its own cryptocurrency for facilitating payments on the platform And much more innovation and exponential growth 6

7 Blockchain Summary A blockchain is a decentralized, distributed digital ledger that is used to record transactions across many computers The record cannot be altered retroactively without the alteration of all subsequent blocks and The consensus of the network This allows the participants to verify and audit transactions inexpensively 7

How do the factions ensure a coordinated attack to sack the city 8
