What Is Ethereum?

Ethereum is a blockchain platform that allows developers to create decentralized apps (dApps) and smart contracts that may be executed on its network. It was launched in 2015. Ethereum smart contracts are self-executing contracts that run automatically when certain predetermined conditions are met.

Ether is the coin used to pay fees and incentives to Ethereum network participants. In addition, it can be used to transfer value across borders and to other network users. Like other cryptocurrencies, Ether is decentralized, meaning a single authority does not control it.

Below are the features of the Ethereum blockchain.

  1. Smart contract platform: Ethereum is primarily known for its ability to execute smart contracts, which are self-executing contracts that can be programmed to trigger actions automatically based on predefined conditions.

  2. Decentralized applications (dApps): Developers can use Ethereum to build decentralized applications that are not controlled by any central authority, allowing for increased transparency, security, and censorship resistance.

  3. Second largest cryptocurrency: Ethereum is the second largest cryptocurrency by market capitalization, with a market cap of over $216 billion as of March 2023.

  4. Ethereum Virtual Machine (EVM): The Ethereum Virtual Machine (EVM) is a runtime environment that allows for the execution of smart contracts on the Ethereum network.

  5. Ethereum Improvement Proposals (EIPs): EIPs are proposals for changes or improvements to the Ethereum network, which are reviewed and approved by the community before implementation. EIPs have played a significant role in shaping the evolution of the Ethereum network over time.

Differences Between Solana and Ethereum

Solana (SOL) and Ethereum (ETH) are popular blockchain networks. Still, they have some key differences, which will discuss in this section based on smart contracts, token addresses, consensus algorithms, transaction fees, scalability, and transaction speed.

Smart Contracts

Ethereum and Solana support smart contracts and decentralized applications (dApps). Still, Ethereum is more established in this area and has a larger developer community.

Token Addresses

On Ethereum, token addresses are represented by the Ethereum address format, a 42-character string starting with “0x”. The first 20 characters represent the token contract address, while the remaining characters represent a unique identifier for a specific token.

On Solana, token addresses are represented by the Solana Address format that starts with a number and a letter, e.g., ‘5f.’ The address is a 44-character string long consisting of a public key and a program ID. The public key is used to identify the token owner. In contrast, the program ID is used to identify the token program on the Solana network.

Consensus Algorithm

Solana uses a proof-of-stake (PoS) consensus mechanism called Proof of History (PoH), allowing faster transaction processing and lower fees. As of September 2022, Ethereum uses the PoS consensus mechanism.

Transaction Fees

Transaction fees on Solana are generally lower than on Ethereum (ETH), especially during periods of high network congestion on Ethereum. This is due to Solana’s efficient PoH consensus mechanism, which allows faster transaction processing times and lower fees. As a result, Solana’s fees are generally lower and more predictable, making it a more cost-effective option for users and developers.

On Ethereum, transaction fees are determined by market demand and network congestion, with fees increasing during periods of high activity. This has resulted in high gas fees, especially for popular DeFi applications and NFT transactions.


Solana has higher scalability than Ethereum, which can handle up to 65,000 transactions per second. In comparison, Ethereum can process up to 15 transactions per second.

Transaction Speed

Solana’s innovative PoH consensus mechanism allows for faster transaction processing times. At the same time, Ethereum has had issues with slow transaction speeds and high gas fees during network congestion.
