Key Takeaways
- Ethereum Classic (ETC) is a decentralized, open-source blockchain platform that runs smart contracts, similar to the original Ethereum (ETH) network.
- Ethereum Classic was launched in 2016 due to a split in the Ethereum blockchain following a hacking incident.
- It uses a Proof-of-Work (PoW) consensus mechanism, unlike Ethereum, which moved to Proof-of-Stake (PoS) in 2022.
What Is Ethereum Classic (ETC)?

Ethereum Classic (ETC) is a decentralized, open-source blockchain platform that supports smart contracts, similar to its more well-known cousin Ethereum (ETH). It originated from the original Ethereum blockchain launched in 2015.
In 2016, a major hacking incident occurred involving The DAO, a decentralized organization built on Ethereum. Hackers exploited a vulnerability and stole significant funds, causing a deep debate within the Ethereum community. The Ethereum blockchain was forked to rectify the situation, creating a new chain (the current Ethereum) where the hack was reversed. Ethereum Classic, however, remained on the original chain, upholding the idea of immutability and the “code is law” principle.
Today, Ethereum Classic presents itself as the original, unaltered Ethereum blockchain, encompassing decentralization, immutability, and adherence to the core blockchain principles.
How Does Ethereum Classic (ETC) Work?
Ethereum Classic (ETC) functions very similarly to its close relative, Ethereum (ETH), but with a key difference: their consensus mechanisms. Here’s a breakdown of how ETC works:

Network Of Nodes
Like most blockchains, ETC relies on a decentralized network of computers called nodes. These nodes work together to verify transactions and maintain the integrity of the blockchain ledger.
Proof-of-Work (PoW) Consensus
Unlike Ethereum, which transitioned to Proof-of-Stake (PoS) in 2022, ETC uses a Proof-of-Work (PoW) consensus mechanism. In PoW, miners compete to solve complex cryptographic puzzles. The first miner to solve the puzzle gets to add the following block of transactions to the blockchain and earn ETC tokens as a reward. Since the Thanos upgrade in November 2020, ETC has used Etchash, a modified version of Ethereum’s Ethash mining algorithm.
Smart Contracts
Similar to Ethereum, ETC supports smart contracts. These self-executing programs run on the blockchain when predetermined conditions are met. Smart contracts enable the creation of decentralized applications (dApps) for various purposes, such as finance, gaming, and supply chain management.
Immutable Ledger
Once a transaction is validated and added to a block, it becomes part of the permanent and immutable public ledger. This ensures transparency and tamper-proof record keeping.

Ethereum Classic (ETC) Token And Tokenomics
Tokenomics
The ETC token is Ethereum Classic’s native cryptocurrency. It is used for:
- Transaction Fees
- Smart Contract Interaction
- Block Rewards For Miners
Token Details
Maximum Supply: 210,700,000 ETC
Circulating Supply: about 158.67 million ETC
Price (early October 2026): about $8.48
Market Capitalization (early October 2026): about $1.35 billion
Price, market capitalization and circulating supply are from CoinGecko as of October 7, 2026, and change constantly.
The supply cap comes from ECIP-1017, which cuts the block reward by 20% every 5 million blocks. The latest cut came at block 25,000,001 on July 22, 2026, when the reward fell from 2.048 to 1.6384 ETC per block.
Distribution
Anyone holding ETH at the time of the fork received the same amount of ETC. This duplicated the existing ETH supply and added it to the new Ethereum Classic chain.
Ethereum Classic Since 2020
ETC was hit by three 51% attacks in August 2020, which reorganized thousands of blocks. In October 2020 the network added a defense called MESS that made long chain reorganizations harder. Developers switched MESS off in the Spiral upgrade in February 2024, because Ethereum’s move to proof of stake had left ETC as the largest network for its kind of mining hardware.
Spiral also brought ETC’s virtual machine closer to Ethereum’s. In July 2025, community developers proposed the Olympia upgrade (ECIPs 1111 to 1114). It would add Ethereum-style EIP-1559 fees and send the base fee to an on-chain treasury instead of burning it. As of October 2026 the proposal is still a draft with no activation block.
The ETC Cooperative has paid for much of the work on the Core-Geth client. Its main income, a share of the fees from the Grayscale Ethereum Classic Trust, ended in March 2022. In its Q3 2025 report, the Cooperative said it was in maintenance mode and would not be sustainable without new sponsors.
Where Can I Buy Ethereum Classic (ETC)?
Binance – Binance is a major exchange offering a wide range of cryptocurrencies. It offers multiple ways to buy crypto, including credit cards, debit cards, and peer-to-peer (P2P) trading.
Bybit – This exchange is known for its derivatives and margin trading features, but you can also use the platform for spot trading.
Coinbase – Coinbase is an American-based cryptocurrency exchange that allows you to buy cryptocurrencies using various payment methods, including bank transfers, debit cards, and wire transfers.
Is Ethereum Classic (ETC) A Good Investment?
Pros
- Immutability – ETC prioritizes the principle of immutability, meaning transactions and code on the blockchain cannot be altered after they are confirmed.
- Fixed Supply – Unlike Ethereum, ETC has a capped maximum supply of about 210.7 million coins, and new issuance drops by 20% every 5 million blocks.
- Decentralization – No central authority governs the network, and decisions are made through community consensus.
Cons
- Smaller Community And Ecosystem – Compared to Ethereum, Ethereum Classic has a smaller developer community and ecosystem. This translates to fewer decentralized applications (dApps) and integrations built on the ETC network.
- Security Risks – Ethereum Classic’s reliance on Proof-of-Work (PoW) consensus makes it susceptible to 51% attacks, in which a malicious actor gains majority control over the mining power to manipulate the network.
- Limited Scalability – The Ethereum Classic network currently faces scalability challenges, which can lead to network congestion and slow transaction times if adoption increases significantly.
Is Ethereum Classic a Good Investment?
Whether Ethereum Classic (ETC) is a good investment depends on your risk tolerance and goals. Remember, this guide only provides a starting point for your research. Always conduct your due diligence before making any investment decisions.
