This document provides an introduction to blockchain and discusses its applications in the energy sector. It defines key concepts of blockchain like distributed ledger, cryptography, consensus, and smart contracts. It also briefly discusses cryptocurrencies and how they aim to function as a medium of exchange, unit of account, and store of value. Blockchain is presented as a key enabler for peer-to-peer energy systems and new energy markets. While the technology is still developing, the future outlook is discussed in the context of digital transformation with blockchain, IoT, and other technologies.

for our clients”

What is Blockchain
A distributed
Ledger with applications beyond Bitcoin
Bitcoin
A currency that leverages
Blockchain technology
BC can enable profound business and
operations transformation
Key concepts
Distributed Ledger
Everyone has the same view of the
ledger and has the same truth
Cryptography
Public key Infrastructure
Integrity and Security of the
information on the BC
Consensus We all agree what the
ledger should look like
Which replaces the need for a third
party to authorize transactions
Smart Contracts
The ability to run additional business logic
means that agreement on the expected
behavior of financial instruments can be
embedded in the BC
In a Distributed System
Eg using Galileo
booking system
Building a system with smart contracts
without human intervention
If we compare where we are in BC
with internet development, we are
building the tcipip layer
A brief foray into
crypto currency
Money
Medium of Exchange
Unit of account
Store of value
Also
Crypto currencies or virtual currencies set out to
mimic those through the combination of
cryptography, game theory and economics
Explaining
“tokens”where BIC is a
token
ICO
Initial Coin Offerings
Eg FileCoin
Uses in energy
Alternative
funding mechanisms
Turning
sunshine into
BIC
People share into
a PV system
EnerChain
Peer to peer energy systems
(Brooklyn Microgrid)
NEM
A new kind of
energy market
BC is a key enabler for this business model but
not the full story mobile smart devices, apis, peer to peer,
etc add more to the puzzle
Game theory
Behavioural economics
Eg SolarCoin
Carbon
Trading
Markets
The future
What’s next for BC?
CryptoKitty
A unique digital asset
With a rarity value
With digital scarcity
Prevents spending the
same currency twice
New tech, blended
Digital Transformation
Web 3.0
BC
IOT
RPA
Robotic Process
Automation
Cloud
AI
Other tech
[Notes]
Discuss the trusted third party
intermediary, Eg the bank or
credit card company
Self regulation in the Voluntary City Friendly
Society with societies being created and creating
their own law (inside the BC)
Technology is
ahead of regulators
What do we need
in a currency?
We must be able to buy something, ie
when we walk into a shop, the shopkeeper
must accept my currency
We need to easily be able to buy and sell the
currency with other currencies, Eg Rands to
Bitcoin, or Rands to Dollars
We need volume
We need volatility
