This presentation is about blockchain. When Thomas Edison invented the electric lamp in 1879, he did not make a market analysis. The market did not have an identified need for a lamp but for light. This is a kind of disruptive original ideas. Satoshi Nakamoto (a person or a group) did not do a market analysis neither . The blockchain was born after the financial crisis of 2008 as people lost trust in banks. Satoshi Nakamoto introduced a new model of trust based on cryptographic proof in a decentralised & distributed ledger. What is bloackchain technology ? Why blockchain is disruptive? And what are the main blockchain technologies ?

5. 3 types of systems

6. Centralized permissioned
Third part trusted system
verifies identities and transactions

7. Dentralized permissionless
Trust comes from the decentralized system
by cryptographic encryption
Nobody can double spend, or double create a
bitcoin or a cryptocurrency

CryptographyGame theory

12. A blockchain is a digitized, decentralized,
public [or private] ledger of all cryptocurrency
public [or any thing of value] transactions.
Constantly growing as ‘completed’ blocks (the most recent transactions)
are recorded and added to it in chronological order, it allows market
participants to keep track of digital currency transactions without central
recordkeeping. Each node (a computer connected to the network) gets a
copy of the blockchain, which is downloaded automatically.

36. Limitations
Technology adoption is still limited(but
will be soon)
PoW consumes lots of energy (eg
Bitcoin)
Regulation is slow

37. Bitcoin Mining Now Consuming More Electricity Than 159
Countries Including Ireland & Most Countries In Africa
