How is it related to Serialization?

Tagged Item?

We need to secure the

database part

✓ This is fine

Blockchain Technology

The Basics

6

Peer2Peer

Blockchain implements

a ‘distributed ledger’

Nodes inter-communicate to update and validate any change. No central facility

7

Basic Structure

Each nodes records all the transactions

applied to this Blockchain –

the entire history

How it works

Network

Each Node stores a linked chain of blocks

Nodes participates via unique pointer (‘URL’)

8

Block Structure

Each blocks contains all

necessary data and pointers

to ensure resistance to unauthorized

change

How it works

#1 (First)

9

Chain Structure

Blocks are interlinked via

hashed pointers

(‘hash’ = unidirectional

encryption using SHA256

algorithm)

Challenges

Mining Costs

Network Depth

Node Implementation

19

Mining Cost Target: < $0.1 per code

Etherium mining uses the

principle of ‘Computational

Wall’ as a barrier to excessive

mining’

Too expensive for the mission

Solution: Private Blockchain

As the number of

codes increases,

the energy required

to mine a new one

increases -

exponentially
