Ethereum's PeerDAS vs. Solana Scaling: Which Wins the Speed Game in 2025?
For years, Solana has been the DeFi’s Ferrari: fast, sleek, and designed for blistering throughput.
Ethereum, meanwhile, has played the role of the secure yet slow semi-truck: low throughput, high fees, but trusted to haul the world’s largest DeFi and institutional value.
But all of that changes on December 3, 2025, when Ethereum launches PeerDAS, a data-availability breakthrough inside the Fusaka upgrade that promises:
8× more data capacity
Sub-$1 swaps on Layer 2 rollups
100,000+ TPS potential through L2 scaling
Is Ethereum finally catching up to Solana or is Solana still too fast to beat?
As of November 2025:
Solana processes 78M+ daily transactions, with fees under a penny.
Ethereum L1 processes ~1.5M, while L2s push that to ~10M.
Post-PeerDAS, ETH aims for 50M+ daily and 12,000–100,000 TPS via rollups.
It’s a battle for the future of DeFi, NFTs, gaming, real-world assets (RWAs), and enterprise blockchain adoption.
Core Architectures: Modular Ethereum vs. Monolithic Solana
Comparing Solana and Ethereum is like comparing a racecar to a fleet of self-driving electric vans.
Solana: The Monolithic Speed Machine
Solana bundles execution, settlement, and data availability into a single L1 engine.
Proof-of-History + Tower BFT
~400ms block times
Theoretical 65,000 TPS
Real-world 950–4,700 TPS after the 2025 compute limit upgrade
Finality in ~12.8s
This “everything on L1” design makes Solana fast, but creates single-state pressure, which has led to congestion and outages.
Ethereum: Modular, Secure, L2-Powered
Ethereum keeps L1 extremely secure and offloads execution to Layer 2 rollups.
PeerDAS changes everything:
Nodes only sample 1–2% of data (instead of 100%)
Bandwidth reduced ~80%
Blobs increased from 6 → 48 per block
L1 capacity rises to ~40–60 TPS
L2 TPS jumps to 10,000+, with a roadmap toward 100,000+ TPS
PeerDAS makes Ethereum’s modular design feel fast without compromising decentralization.
Winner (Architecture):
Solana for raw speed today. Ethereum for long-term scalability and security.
TPS & Throughput: Solana’s Sprint vs. Ethereum’s Marathon
Real-World TPS Comparison (ETH vs SOL Nov 2025)
Solana TPS Strengths
Handles memecoin and perps mania (1,800 TPS during 2025 frenzy)
Processes 60% of perp DEX volume
Lightning-fast UX
Weakness: Spam attacks can cause 2–4 hour outages, five between 2024–2025.
Ethereum TPS Strengths
PeerDAS enables 12,000 TPS by 2026 (comparable to Visa)
Zero downtime since 2015
Prioritizes safety over hype
Winner (TPS):
Solana in 2025; Ethereum by 2026 if scaling plays out.
Fees & Costs: Pennies vs. Predictable Scaling
Solana Fees (2025)
Sub-$0.01 average
Perfect for gaming, social apps, microtransactions
$9B DeFi TVL
Ethereum Fees
L1: $2–$5 during peaks
L2s: $0.05–$0.20 post-Pectra
PeerDAS: 50–70% cheaper L2 blobs → sub-penny swaps
Example: Uniswap on Base drops from ~$1 → $0.10
Winner (Fees):
Tie. Solana is cheaper today, Ethereum catches up with PeerDAS.
Decentralization & Reliability: The Security Showdown
Ethereum: The Security King
1,000+ Nakamoto coefficient
1T+ secured on-chain
Can run a node on Raspberry Pi post-PeerDAS
10+ years without outages
Rollup diversity reduces systemic risk
Solana: Incredible Speed, Lower Redundancy
~844–903 validators
Nakamoto coefficient: ~20
Stake-weighted QoS favors large validators
Multiple outages (4+ hour halt in 2024)
Winner (Security & Reliability):
Ethereum by a wide margin.
Ecosystems: Who’s Building the Future?
Ethereum
$500B+ DeFi TVL
$10B NFT market
80% of stablecoins run on ETH rails
Institutional dominance: ETH ETFs, staked ETH, RWAs
Fusaka + PeerDAS could anchor $1T+ on-chain assets by 2026
Solana
2.3M+ daily active users
Strong meme coin, gaming, and social presence
78% developer growth
ETFs from Fidelity & BlackRock
$9B TVL
The “consumer chain” of crypto
Winner (Ecosystem):
Ethereum for depth; Solana for UX and growth.
Future Outlook: Who Wins in 2026?
Ethereum’s Path
PeerDAS + Danksharding → 100,000 TPS
No outages
Highest security
Enterprise adoption momentum
Solana’s Path
Firedancer (Q2 2026) → 1M+ TPS
Alpenglow: 150ms finality
Still working on decentralization and reliability
Prime hub for perps, gaming, memes, and high-frequency apps
Analyst Consensus
ETH ≈ $10,000 roadmap
SOL ≈ $1,000–$2,000 roadmap
Multi-chain world: ETH = security base layer, SOL = high-speed user layer
Final Verdict
PeerDAS finally makes Ethereum fast, while Solana continues to dominate the UX race. Both chains will likely win because they serve different purposes in a multi-chain future.
