The Future of Scalability Benchmarks: Moving Beyond Peak TPS

Advertised 100,000 TPS is meaningless if the network is congested during a memecoin frenzy. Peak capacity ignores real-world constraints like state growth, mempool dynamics, and validator load.

• Real Bottleneck: State bloat and I/O, not CPU.
• User Impact: High latency and failed transactions during peak demand.
• Industry Shift: Projects like Solana and Sui now emphasize Time-to-Finality and concurrent execution.

True scalability is measured from user click to guaranteed settlement. This stack includes sequencer inclusion, proof generation, and cross-chain verification.

• Key Layer: EigenDA and Avail decouple data availability from execution.
• Bottleneck Shift: Proof generation time on zkEVMs like zkSync and Scroll.
• New Metric: Settlement Assurance Time, combining soft and hard finality.

A chain can be fast in a vacuum but crumble under cross-chain load. The real network is a multi-chain system where LayerZero messages, Circle's CCTP transfers, and Wormhole NFTs create interdependent load.

• New Stress Test: Simultaneous bridge withdrawals and DEX arbitrage.
• Systemic Risk: Congestion on L1 (Ethereum) cascades to all L2s (Arbitrum, Optimism).
• Benchmark Gap: No standard for measuring cross-rollup congestion.

Forget cost-per-transaction. Protocols and users care about cost-per-dollar-settled. This measures economic efficiency for high-value DeFi, NFT mints, and institutional transfers.

• VC Focus: Andreessen Horowitz (a16z) and Paradigm track this for portfolio chains.
• Protocol Example: Uniswap v4 hook execution cost vs. swap value.
• Real Scaling: A chain that's cheap for $10 swaps but expensive for $10M swaps has failed.

Scalability isn't just for users. Complex state access patterns, non-standard precompiles, and unpredictable gas costs on chains like Polygon zkEVM or Base cripple developer iteration speed.

• True Cost: Weeks of optimization for simple contracts.
• Ecosystem Risk: Developers flock to chains with predictable performance (Arbitrum Stylus, Fuel).
• Missing Benchmark: Time-to-first-successful-complex-dApp.

The next benchmark standard will be continuous, adversarial simulation. Services like Chaos Labs will stress-test chains with realistic, malicious load to find breaking points before hackers do.

• Simulate: NFT mint rushes, oracle manipulation, and governance attacks.
• Benchmark: Sustained TPS under attack, not ideal conditions.
• Outcome: A security-scaling score for VCs and protocols.

Advertised 1M TPS is meaningless if node hardware requirements double yearly. The real bottleneck isn't computation, but state bloat that centralizes infrastructure.

• Solana's ~1.2 TB annual state growth demands enterprise-grade hardware.
• Ethereum's ~1 TB full archive node size is mitigated by Erigon's flat structure.
• The benchmark that matters: State Growth per 1000 TPS.

Sustainable scaling is measured by how costs behave during a mempool flood. Base fee volatility is the true stress test.

• Ethereum L1 fees can spike to $200+ during an NFT mint.
• Solana fails this test entirely during congestion, requiring priority fees and experiencing ~50% failed tx rates.
• Arbitrum Nitro and zkSync Era maintain sub-$0.10 median fees by leveraging L1 security for data, not execution.

Users experience latency distributions, not averages. A chain with 2s avg finality but a 60s 99th percentile is unreliable for DeFi.

• Avalanche subnets achieve ~1-2s finality but can suffer from cross-subnet latency.
• Polygon zkEVM leverages Ethereum for ~10 min finality, trading speed for supreme security.
• The key metric is Finality SLA: % of transactions final within a guaranteed window.

High TPS often requires sacrificing validator decentralization. The critical ratio is Nodes / Throughput.

• Solana's ~1,500 validators support high TPS but with high hardware costs, creating centralization pressure.
• Celestia's data availability sampling allows light nodes to scale with the network, preserving decentralization.
• Monad's parallel EVM targets 10k TPS but its decentralization will be proven by its validator set size at launch.

Protocols must be evaluated on the full cost to secure and use them: L1 security costs + L2 operational costs + cross-chain messaging fees.

• Optimism's Bedrock upgrade reduced L1 data costs by ~50%, directly lowering TCO.
• zkRollups like StarkNet have high proving costs but near-zero L1 settlement costs, optimizing for high-volume batches.
• Polygon 2.0's interconnected ZK L2s aim to minimize TCO via shared liquidity and security.

Generic TPS is dead. Scalability is now measured per use case: Perps Latency, NFT Mint Gas Cost, Cross-Swap Slippage.

• dYdX v4 on Cosmos is built for ~1,000 orders/sec with sub-10ms matching engine latency.
• Immutable zkEVM benchmarks >100k NFT mints for < $1 total gas, a metric irrelevant to Uniswap.
• The future is benchmark suites, not single numbers.

Advertised peak TPS ignores the real bottlenecks: state growth, cross-domain latency, and the cost of finality. A chain claiming 100k TPS is meaningless if its state becomes a 10 TB archive or cross-chain messages take 10 minutes.

• Key Insight: Measure time-to-finality and cost-per-finalized-transaction, not raw throughput.
• Action: Audit scaling claims by testing sustained load under adversarial conditions (e.g., spam attacks).

Scalability is now a system design problem. Decouple execution (Rollups, Solana), settlement (Celestia, EigenLayer), and data availability.

• Key Insight: Modular stacks (e.g., using Celestia for DA) can reduce L2 operating costs by >90%.
• Action: Build for intent-based flows (see UniswapX, CowSwap) where users declare outcomes, not transactions, abstracting away chain boundaries.

Real scalability is value moved securely per unit time. A chain with $1B TVL and high velocity is more scalable than one with $10B TVL that's stagnant.

• Key Insight: Track Total Value Secured (TVS) and capital rotation rates. Protocols like EigenLayer monetize security directly.
• Action: For L1s/L2s, incentivize high-value, high-frequency applications (DeFi, gaming) not just NFT mints.

Scalability is worthless if it's siloed. The future is multi-chain, requiring seamless asset and state movement.

• Key Insight: Universal interoperability layers (LayerZero, Chainlink CCIP, Axelar) and shared security models (Polygon AggLayer, Cosmos IBC) are critical infrastructure.
• Action: Evaluate bridges and messaging protocols on latency (~2-5 sec for optimistic, ~1 min for zk), security guarantees (economic vs. cryptographic), and cost.

Users don't care about block time; they care about perceived speed from click to confirmation. This requires optimizing the entire stack, from RPCs to pre-confirmations.

• Key Insight: Instant pre-confirmations via threshold encryption (e.g., EigenLayer) or fast-finality chains (Solana, Sei) set the new UX standard.
• Action: Implement local fee markets and priority lanes to guarantee sub-second feedback for end-users, even during congestion.

High throughput that bankrupts validators or relies on unsustainable token emissions is a dead end. Fee revenue must cover hardware and security costs.

• Key Insight: Analyze a chain's cost-of-production (hardware, bandwidth) vs. protocol revenue. Solana and Monad push hardware limits; Ethereum L2s inherit security but pay for it.
• Action: For investors, model validator profitability. For builders, design for real fee revenue, not just token incentives.
