Abstract
Blockchain technology promises decentralized
applications but faces scalability challenges, particularly in smart contract
execution. This study empirically benchmarks Ethereum’s Proof-of-Stake (PoS)
against Solana’s Proof-of-History with Byzantine Fault Tolerance (PoH+BFT) by
deploying identical smart contracts written in Solidity for Ethereum and Rust
for Solana on public testnets and executing controlled simulations using
standardized scripts. Performance was evaluated using Transactions Per Second (TPS),
latency, and transaction cost under controlled conditions. Results show Solana
significantly outperformed Ethereum, achieving 1,823 TPS versus 47 TPS, 0.9s
latency versus 13.2s, and $0.00025 average transaction cost compared to $0.42,
with lower CPU utilization (36% vs. 54%). These findings confirm Solana’s
technical advantage for high-throughput, low-cost applications, while
Ethereum’s ecosystem and stronger decentralization remain compelling for
broader adoption. Overall, this research provides one of the first empirical
smart contract-level comparisons between Ethereum and Solana, highlighting
trade-offs between performance and decentralization, offering practical
insights for developers and organizations, and contributing to cross-platform
benchmarking, consensus mechanism evaluation, and blockchain scalability
research.
