What is BLOCKCHAIN? ❓
P2P network Blockchain is a decentralized P2P network. Decentralized
Why decentralize? Every time you use the Internet, you have
to access a server from your device. Current Internet Server
Problems of the Internet.
Equifax data breach Hackers exposed the Social Security numbers, drivers
licenses and other sensitive info of 143 million Americans
Edward Snowden’s confession Edward Snowden whitsleblower of The NSA surviilance
If decentralized... Transparent
Safer when hacked
Hard to supervise
P2P network What is P2P and Why?
If P2P...
You don’t have to rely on a third party. “Trustless”
How does BLOCKCHAIN work?
Blockchain contains blocks connected to chain.
What is Minning? Gold Bitcoin
Each block contains a “previous block hedder”. transactions transactions transactions
previous block hedder previous block hedder previous block hedder nonce nonce nonce Block hedder Block hedder Block hedder Block n Block n+2 Block n+1
If changed... Each block contains a“previous block hedder”.
Blockchain is like multiple layers. New blocks Recent blocks Old
blocks Very hard to change Almost impossible to change You shouldn’t even think about changing them
Blockchain is immutable. immutable
Why Bitcoin matters? Blockchain Users Miners (12.5BTC+Fees) Transaction Transaction Transaction
want to use Bitcoin but also want someone to check the transactions. want to earn Bitcoin.
Summary Blockchain is... Decentralized P2P Transparent Immutable Bitcoin is... Decentralized
Autonomous
Thank you
