Why Ethereum Classic?
“Do not go gentle into that good night..”
- Dylan Thomas
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.
Ethereum Website
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
Minimising Points of FailureDecentralization 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
Administration• Governance• Finance Management• Risk Control
Decentralized Infrastructure

compiler● Establishing communication channels
for global coordination and consistency
● Setup global meetups to begin deployment of decentralised community network
● Define framework for Dapp developers
● Defining core social contract● Defining community-driven roadmap● Define governance models for
execution● Design/deploy funding mechanisms
for key infrastructure (build/testing servers, ETC-testnet, web hosting)
● Execute PoW, PoS or Hybrid cons mech
● Execute appropriate monetary policy● Test/implement state sharding● Research/test VM improvements if
deemed fit for implementation
● Further outreach to miners● Extend meetups and conferences● Setup of overall Dev conference ● Deployment of structured Dapp dev
ecosystem and support framework e.g. hackathons and 3rd party funding
3rd Party Products and Services
Ethereum Classic Core Development
“Necessity is the Mother of Invention”- Plato’s Republic
Core DevelopmentGrowing ETC Development Team on github repository, which is currently being organized and structured for sustainable development of the core infrastructure
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
Difficulty BombOverview• 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
Fix ETC Monetary PolicyOverview• 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
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
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
UI Components For Dapp DevsOverview• 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
ETC Wallet AppOverview
• 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
Java ETC for Fintech & CorporatesOverview
• 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
