In lessons 1 to 5 of this course, we explained how Proof of Work (POW) operates in detail.
For Ethereum Classic (ETC), POW benefits include:
- Decentralization
- Hard money
- Permissionless access
- Censorship resistance
In Lesson 6, we explore Ethereum Classic’s advantages over Bitcoin (BTC) and Ethereum (ETH).
Satoshi Nakamoto Originally Planned Smart Contracts for Bitcoin
Satoshi Nakamoto envisioned Bitcoin’s programmability, as shown in his June 2010 comment:
"The design supports all kinds of transaction types I designed years ago. Escrow, bonds, third-party arbitration, multi-signature contracts, etc. If Bitcoin gains traction, these will be explored later—but they must be designed upfront to ensure future compatibility."
– Satoshi Nakamoto
This reveals Nakamoto’s alignment with cypherpunk ideals—where monetary innovation, Bit Gold, and smart contracts were pioneered.
Why Smart Contracts Failed on Bitcoin
Bitcoin’s design inherently restricts smart contract functionality due to:
- A limited scripting language
- The Unspent Transaction Output (UTXO) model
Attempts like Colored Coins and MasterCoin tried adding programmability but faced technical barriers. Ultimately, Bitcoin remained a pure cryptocurrency.
The Invention of Ethereum Classic
Vitalik Buterin created Ethereum Classic (original Ethereum) to merge digital gold (like BTC) with programmability (via smart contracts).
Key innovations:
- Account system (replacing UTXO)
- Ethereum Virtual Machine (EVM)
- Smart contract execution
- GAS system (preventing spam/ensuring miner payments)
Smart contracts became blockchain’s second-most pivotal invention after Nakamoto Consensus.
The 2016 Split: Ethereum vs. Ethereum Classic
Two chains emerged after Ethereum’s community forked the original blockchain to reverse a $50M hack of TheDAO (a decentralized fund).
Ethereum Classic (ETC) upheld immutability by preserving the unaltered chain, while Ethereum (ETH) implemented the fork.
👉 Why ETC’s immutability matters
Ethereum’s 2022 Shift to Proof of Stake
In September 2022, Ethereum abandoned POW for Proof of Stake (POS), leaving ETC as the largest POW smart contract blockchain.
ETC’s hash rate surged from 25 TH/s to 200+ TH/s, stabilizing at ~150 TH/s—showcasing robust security.
ETC: Bitcoin’s Philosophy + Ethereum’s Technology
Ethereum Classic uniquely merges:
- BTC’s hard-money ethos (fixed supply)
- ETH’s programmability (smart contracts)
Result: Programmable digital gold.
Key Advantages of Ethereum Classic
| Advantage | ETC | BTC | ETH |
|---|---|---|---|
| POW Security | ✅ | ✅ | ❌ |
| Smart Contracts | ✅ | ❌ | ✅ |
| Fixed Supply | ✅ | ✅ | ❌ |
| Full Replication | ✅ | ✅ | ✅ |
| Composability | ✅ | ❌ | ✅ |
| Largest POW Smart Chain | ✅ | ❌ | ❌ |
ETC’s 7 core strengths make it the most secure platform for decentralized applications.
FAQs
Q1: Why is ETC more secure than ETH?
A1: ETC retains POW’s battle-tested security, while ETH’s POS is newer and less decentralized.
Q2: Can ETC scale like Ethereum?
A2: Yes—layer-2 solutions (e.g., Sidechains) are compatible without sacrificing POW.
Q3: How does ETC’s fixed supply work?
A3: Like BTC, ETC has a hard cap (~210M ETC), ensuring scarcity.
