Why Ethereum
Classic?
“Do not go gentle into that good night..”
- Dylan Thomas

4. What Really Went Wrong
… until something goes
wrong that impacts the
interests of a centralized
authority?
The failure of the DAO was not just a program failure, but a failure in risk
management; and it also exposed an even deeper failure of the underlying social
contract: Ethereum transaction/programs would never be changed by a third party.

5. Birth of Ethereum Classic
● “Code is Not Law”: The infrastructure is not there to enforce and uphold law, it's only
a protocol that allows execution of immutable transactions and programs
● User Responsibility: Developers and entrepreneurs need to understand and take
responsibility for legal and regulatory requirements to protect customers
● Legal Recourse: If anything goes wrong the infrastructure can not be controlled into
changing its state, recourse for financial crime and other illegal activities needs to take
place through normal channels
● Protocol Fixes and Updates: Only changes to fix protocol level bugs and implement
updates/upgrades are acceptable at the infrastructure level
Saying “Code is Law” implies infrastructure on which it runs is responsible for
upholding the law… infrastructure is not responsible for greed, ignorance or malicious
behaviour - same as in phone networks, internet and even on the road

6. Minimising Points of Failure
Decentralization of infrastructure is not sufficient; all key aspects of the ecosystem
require a certain level of decentralization to minimize points of failure
Decentralization
of all aspects of
ETC Ecosystem
Technology
• Core Dev/Support
• Operations
• R&D
Community
• Marketing
• Education
• Dapp Dev

● Research/test VM improvements if
deemed fit for implementation

9. Core Development
Growing ETC Development Team on github repository, which is currently being organized and structured
for sustainable development of the core infrastructure

10. Core Dev Focus Points
1. Diffuse Difficulty Bomb
2. Fix ETC Monetary Policy and Possible Options
3. ETC Dapp Browser for End Users
4. UI Components For Dapp Devs
5. ETC Wallet app
6. Java ETC for Fintech and Corporates

11. Difficulty Bomb
Overview
• Difficulty Bomb - exponentially growing
difficulty of Ethereum mining
• Time between mined blocks will become
longer and longer
• Eventually, “final doom” occurs, when no
more blocks can be mined at all
• Serves no useful purpose, other than to break
PoW consensus and push users to PoS
• will make PoW impractical by early 2017
• Diffusing diff bomb is in best interest of all ETC
users and makes PoW viable for long-term
• Long-term decision of ETC consensus algo will
be based on data in 2018, with possibilities
such as PoW, PoS or a hybrid PoW/PoS
Plan
• Changes to: GO-Ethereum, CPP-
Ethereum, EthereumJ,
PyEthereum EthCore Parity
• Implementation needs to be ready
and fully tested by November
2016
• Deployment by end of 2016
• 1-3 months to release
• Mostly part time, but a lot of testing
• Many people involved, pretty much
every ETC project needs to update
• $50,000 to $100,000

12. Fix ETC Monetary Policy
Overview
• Platform token aligns economic incentives of
users, miners and investors
• Current Ethereum monetary policy undefined
(unlimited token inflation)
• ETH policy is supposed to change with a
transition to PoS unpredictably
• Lack of token scarcity does not support long-
term investor confidence
• ETC transition to a long-term PoW necessitates
monetary policy decision
• ETC commitment to a specific monetary policy:
1. provide certainty to the market
2. boost investor confidence
3. creates competitive differentiator to ETH with its
undefined policies
Plan
• Review monetary policy models
and assess pros and cons
• Review in parallel to ETC Diff-
bomb fix, with target to
implement when diff-bomb
hard fork executed
• Any consensus parameters
can be adjusted to comply to
this policy
• Potentially gain research
support from universities

13. Keep unlimited token inflation forever, like current ETH
• Pros: keeps the status quo, encourages token spending
• Cons: long-term monetization uncertain, not a good store of value/investment
Fixed final supply with Bitcoin-like reward cut-offs (halvings)
• Pros: experimentally proven to work for BTC, sustainable token monetization due to scarcity
• Cons: changes existing inflationary parameters, disruptive “halving” events
Fixed final supply with exponential reward adjustments (per epoch)
• Pros: no disruptive “halvings”, sustainable token monetization due to scarcity
• Cons: changes existing inflationary parameters
Fix ETC Monetary Policy - Options

14. ETC Dapp Browser for End Users
Overview
• A DApp Browser is a desktop application
with an embedded browser to run web
applications that operate with Ethereum
Blockchain and Smart Contracts.
Examples: ETH Mist, Metamask
• It’s a key user facing application, and
provides the window for the wider
world into the Blockchain
• ETC cannot rely on ETH Mist because
the communities have different visions
and are moving in different directions
• Existing Mist have many UI/UX issues
and too slow, people will are keen to
use alternatives
Plan
• Write Launcher and bundled Dapps
1. Wallet
2. Tokens
3. Contracts Viewer
• Long project, ~3-5 months to first public
release for team of 2-4 devs
• QA, design and management
• Requires continuous improvement after
initial launch (planned Q1 2017)
• Project can be split in smaller milestones
• $200,000 for first public release

15. UI Components For Dapp Devs
Overview
• Important to provide Classic Ethereum
guidelines, and use ETC Brand with 3rd
party Dapps
• Existing ETH UI components under LGPL,
cannot be used by commercial companies
• Targets Dapp Developers community,
need to attract new Dapp developers by
giving:
– Ready to use UI components
– And reusable design style
– Bootstrap code samples and documentation
• Ideally ETC should have a Developer
Advocate to make it easy using ETC stack
by other developers
Plan
• JavaScript UI Components for modern
frameworks (React, Angular)
• Rich documentation and website with
examples
• Open Source, commercial friendly
license (MIT/BSD/Apache2)
• 2-3 developers, graphical designer
• 1-2 month
• $30,000

16. ETC Wallet App
Overview
• The most popular demanded feature for a
wallet app is to check current balance,
accept incoming transfer, send a
transaction, or possible sign a multisig
transfer
• ETH Mist it too slow for this task and
focused on Dapps services
• ETC needs a lightweight native
application Focused on only one function:
Wallet services, without Dapps
• Need to support standard token contracts
and multisigs
Plan
• 1-2 go/rust developers
• UX design, graphical design
• QA
• 2-3 months for a first
public release
• $40,000-$50,000

17. Java ETC for Fintech & Corporates
Overview
• Java & JVM is main platform for corporates
and banks
• Challenging to use NodeJS and other “cool”
tools in enterprise development, CTOs will
never agree on that
• ETH doesn’t provide any tools for Java, it’s
hard to use in enterprise, this a blocker
• Ethereum lacks tools for integration testing
and code analysis - required for corporate
development
• As Ethereum is becoming the main
blockchain and smart contracts platform
ETC is going to implement a set of tools for
Ethereum for Java
Plan
• Set of small independent projects:
1. Java API to ethereum blockchain
2. Smart Contract management tools for Java
3. Testing environment integrated with JVM
test tools
4. Plugins for major IDEs (run, syntax helpers)
5. Plugins for major build tools (reports, code
generators, integrations)
• 1-2 man-month per project
• About $10,000 per project

(OpenSource)
Fundonomy is a platform for ETC community to launch a project funding contract on the ETC Blockchain,
with no technical experience required, and receive ETC funding from contributors. Contributors can also
judge performance and use the platform to record scores in an open reputation utility contract

27. ETC is Key Component in the Stack
Web Application Layer – Is about information sharing
• Powerful project marketing tools to spread messages
across all social networks with a single user friendly
interface
• Communications and group management tools to
enables users to manage campaigns before, during
and after they launch
• Allows users to build communities and relationships
Blockchain Layer – Is about storing and managing
value
• Collection of funds at little or no cost
• Holding of funds securely that release on key triggers
e.g. dates, completion of milestones etc
• Reputation score becomes a source of value that
should be independent of anyone party and can
become a utility that can be tapped into for any funding
contract on or off fundonmy
