Origin and Development History
Birth Background
Ethereum was created by Vitalik Buterin and co-founders in 2015, aiming to solve the inability of Bitcoin to support complex programmable logic and decentralized applications.
It emerged during the blockchain technology boom, with the goal of providing a platform for developers to build decentralized applications without intermediaries and transforming the current landscape.
The launch of Ethereum brought unprecedented possibilities to developers, entrepreneurs, and users seeking financial sovereignty.
Key Milestones
- 2015: Mainnet launch, realizing smart contract functionality and decentralized application support.
- 2020: Launch of the Beacon Chain, initiating the transition to Proof of Stake consensus mechanism.
- 2022: Completion of The Merge upgrade, successfully transitioning from Proof of Work to Proof of Stake, reducing energy consumption.
- 2025: Ecosystem explosion, with DeFi protocols and NFT platforms continuing to flourish across the network.
With support from the Ethereum Foundation, developer community, and ecosystem participants, Ethereum continues to optimize its technology, security, and real-world applications.
How Ethereum Works
No Central Control
Ethereum operates on a decentralized network of computers (nodes) distributed globally, free from control by banks or governments.
These nodes collaborate to validate transactions, ensuring the system remains transparent and attack-resistant, granting users greater autonomy and enhancing network resilience.
Blockchain Core
Ethereum's blockchain is a public, immutable digital ledger that records every transaction.
Transactions are grouped into blocks and linked through cryptographic hashes to form a secure chain.
Anyone can view the records, establishing trust without intermediaries.
Layer 2 scaling solutions such as Rollups further enhance performance and transaction throughput.
Ensuring Fairness
Ethereum adopts Proof of Stake (PoS) to validate transactions and prevent fraudulent activities such as double-spending.
Validators maintain network security through staking ETH and running validator nodes, earning ETH rewards in return.
Its innovation includes significantly reduced energy consumption compared to Proof of Work while maintaining high security.
Secure Transactions
Ethereum uses public-private key cryptography to protect transactions:
- Private keys (like secret passwords) are used to sign transactions
- Public keys (like account numbers) are used to verify ownership
This mechanism ensures fund security while transactions maintain pseudonymity.
Additional security features include support for multi-signature wallets and ongoing research into zero-knowledge proof technologies.
Circulation Overview
As of 13 January 2026, Ethereum's circulating supply stands at 120,694,705.62 ETH, with a total supply of 120,694,705.62 ETH. The platform operates on an inflationary model where new coins enter the market through block rewards and transaction fee mechanisms, which influence its supply-demand dynamics. The circulating supply represents 100% of the total supply, indicating full market availability.
Price Volatility
Ethereum reached its highest price of $4,946.05 on 25 August 2025, driven by favorable market conditions and increased adoption. Its lowest price was $0.432979, recorded on 20 October 2015, during the early stages of the platform's development. These fluctuations reflect market sentiment, adoption trends, and external factors affecting the broader cryptocurrency ecosystem.
