Similar to the comparison of Android and iOS, or Microsoft and Mac, the cryptocurrency field features a significant rivalry between Ethereum and Solana—two of the foremost decentralized blockchain platforms competing for prominence in the decentralized finance (DeFi) landscape.
This guide explores the distinctions between Ethereum and Solana by examining the essential features and architectures of each blockchain, outlining their advantages and drawbacks for users and developers alike.
We’ll begin with the basics before delving into the more intricate elements.
What Is Ethereum?
Ethereum ranks as the second-largest blockchain protocol and is the leading DeFi platform for decentralized applications (dApps). It hosts a variety of major crypto projects, encompassing liquid staking, decentralized exchanges (DEXs), and platforms for tokenizing real-world assets.
Regarded as the trailblazer of DeFi, Ethereum was one of the first blockchains to integrate smart contracts, all thanks to the Ethereum Virtual Machine (EVM), which revolutionized smart contract execution within blockchain protocols.
The EVM is tasked with executing smart contracts and overseeing the state of the Ethereum network. The term “state” essentially refers to the current condition, or snapshot, of all data stored within the system at any moment. This encompasses everything from an account’s balance to the smart contract code itself.
State transitions describe how the blockchain’s state evolves in reaction to transactions. When a transaction is conducted on Ethereum, the state transitions occur, meaning the existing state (the previous data) is updated to include the new transactions and generate a revised state.
Why is the state significant in Ethereum?
- Accountability: Users can always verify account balances and the status of contracts.
- Smart Contract Execution: The Ethereum Virtual Machine (EVM) relies on the state to determine the behavior of smart contracts during execution.
- Consensus: Each computer within the network maintains its own version of the world state, ensuring uniformity and preventing potential conflicts.
Instead of being inscribed directly onto a blockchain (akin to a permanent ledger), this world state is organized within a Merkle Patricia Trie (MPT), a structure created for efficient searching and updating. Each transaction prompts an update to the world state to reflect the alterations made.
Additionally, the EVM utilizes a stack-based architecture, which processes data by temporarily storing it in a stack while contracts are executed. This framework is essential for how Ethereum manages and operates its decentralized system.
The image above illustrates the key components of the EVM:
- Stack: This component holds temporary data during contract execution, operating with 32-byte items that allow operations like pushing (adding) and popping (removing) values from the stack.
- Memory: A volatile, linear storage space that retains temporary data only throughout a transaction’s duration, accommodating data types such as arrays and strings, which are cleared after the transaction ends.
- Storage: A permanent storage area retaining contract-specific information, such as balances and code hashes, persisting after transactions, mapping 32-byte keys to associated values.
- Program Counter (PC): A pointer signaling the next operation to execute from the bytecode.
- Gas: A measurement unit that quantifies computational work, with each operation consuming a defined amount of gas, which helps prevent misuse of the network by controlling resource utilization.
Ethereum’s architecture also comprises numerous other technical specifications that expanded following the network’s transition from PoW to PoS, enhancing energy efficiency. These and other aspects will be explored in subsequent sections of this guide.

What Is Solana?
Solana stands as a prominent blockchain, boasting an ecosystem rich with outstanding DeFi projects.
The platform employs an intricate architecture and toolset to ensure scalability and achieve rapid block processing speeds, capable of handling over 60,000 transactions per second. This enables users and developers to trade digital assets and develop decentralized applications (dApps) with remarkable ease and efficiency.
Solana is powered by a highly sophisticated consensus algorithm known as Proof of History (PoH).
Proof of History (PoH): Solana’s Cryptographic Clock
PoH serves as Solana’s consensus mechanism and is instrumental in its scalability.
This algorithm generates a verifiable record of events occurring at specific intervals on the network. It utilizes a high-frequency Verifiable Delay Function (VDF) to ensure that each block producer has adequately waited before creating the next block.
PoH integrates with Solana’s PoS-based Tower BFT—Byzantine Fault Tolerance—algorithm, an enhanced version of the Practical Byzantine Fault Tolerance (PBFT) protocol that utilizes the PoH-based cryptographic clock to minimize the time and energy necessary for nodes to reach consensus. This method also addresses common issues such as varying node speeds and rollback costs, facilitating seamless and secure operations.
Moreover, Solana’s PoH employs the SHA256 algorithm (a cryptographic function also used by Bitcoin) to create a sequence of hashes. Validators document specific information linked to the hash index, with timestamps generated as data is integrated into the chain. This timestamping process permits Solana to handle thousands of transactions per second without the need for conventional node-based validation for each transaction.
