Ethereum’s mainnet is organized into three core layers, each serving a specific function to make the blockchain secure, functional, and decentralized. These layers—Data Availability Layer, Consensus Layer, and Execution Layer (EVM)—are essential for Ethereum’s operation. Together, they form a complete blockchain but are separated based on tasks, not physical boundaries. Each layer is contained within Ethereum’s validator nodes, creating a unified yet modular architecture.
Running these programs requires computational power, and just like running any machine, it costs a fee, known as gas. These computation requests consume resources and are paid for using a metered system called gas. This mechanism ensures that the network remains efficient and prevents abuse of computational resources.
Understanding ETH: The Native Token
By using smart contracts and distributed systems, customers can easily build secure decentralized financial applications. For example, DeFi companies are already offering products that enable peer-to-peer lending and borrowing, earning interest on cryptocurrency holdings, trading via decentralized exchanges, and much more. Some popular DeFi platforms include Compound, Aave, UniSwap, and MakerDAO. Its native cryptocurrency, ether (ETH), powers transactions and computational services on the network, facilitating a wide range of applications from decentralized finance to NFTs. The ether spent to power transactions is known as ‘gas’ and is the cost of using the network. Ethereum is a revolutionary blockchain platform that enables developers to create decentralized applications and smart contracts.
- However, Ethereum appears to have a significant, upcoming role in personal and corporate finance and many aspects of modern life.
- In the next section, I will explain how credible block space motivated the rise of the Ethereum Layer 2 ecosystem.
- While it sounds like the perfect platform, Ethereum has a few key issues that need to be worked out.
- This approach required miners to solve complex cryptographic puzzles to validate transactions and create new blocks.
- Ethereum is a decentralized blockchain platform that establishes a peer-to-peer network that securely executes and verifies application code, called smart contracts.
Blockchain is a distributed ledger that records transactions across a network of computers securely and transparently. Each block contains a list of transactions, linked cryptographically to the previous block, forming an immutable chain.

Benefits of building on Ethereum
Their computer power is “proof” of that work, and miners are rewarded in ETH for their efforts. With more blobs per block, Ethereum can handle even greater volumes of transactions off-chain, further reducing congestion and gas fees on the mainnet. Through this layer, Ethereum achieves consensus on legitimate transactions and finalized, making it resistant to double-spending attacks and network manipulation. The Consensus Layer keeps Ethereum decentralized, as validators work together to maintain and secure the chain. One of EIP-1559’s key impacts has been its effect on ETH supply dynamics.
What is Ethereum (ETH) and How Does it Work?
Its adaptability and active community position it as a leading force in blockchain technology. Security vulnerabilities in smart contracts pose risks, https://tokenestra.com/de-ch/ as flawed code can be exploited, leading to financial losses. Regulatory uncertainties also may impact adoption and operation in various jurisdictions.
There isn’t a cap on the total number of ETH that will go into circulation, but its current supply of about 120 million is expected to remain relatively stable.

Ethereum’s merge may convince skeptics that blockchain technologies can work without a huge environmental cost. Ethereum, like Bitcoin, had historically used a “proof-of-work” system to ensure that transactions on the network are recorded correctly. Ethereum has now moved to a “proof-of-stake” system, which instead uses a process known as staking. Axie Infinity is another game that uses blockchain technology and has its own cryptocurrency called Smooth Love Potion (SLP). Anyone can use Ethereum—it’s designed to be scalable, programmable, secure, and decentralized—to create any secured digital technology. Its token is designed to pay for work done supporting the blockchain, but participants can also use it to pay for tangible goods and services if accepted.
The price tested the $1,565 zone, forming a low at $1,564 before starting to consolidate. By integrating these features, the Pectra Upgrade aims to make Ethereum more accessible, efficient, and scalable, benefiting both everyday users and developers within the ecosystem. One proposed solution to address this challenge is to prune blob data older than one month from the mainnet.
