Architectural Differences

Aptos: Parallel Execution via Block-STM

Account-based model with concurrent transaction processing.
Block-STM engine optimizes throughput by validating dependencies post-execution.
Modular upgrades enable seamless governance.

Sui: Object-Centric Scalability

Independent object operations bypass consensus for simple transactions.
Horizontal validator scaling claims "near-unlimited" capacity.
Optimized for low-latency use cases like gaming and social apps.

Consensus Mechanisms

| Feature | Aptos (BFT Consensus) | Sui (Narwhal + Bullshark) |
|--------------|----------------------|--------------------------|
| Finality | ~0.9 seconds | 2-3 seconds (theoretical) |
| Security | Byzantine Fault Tolerance | Parallel validator processing |
| Use Case | High-frequency DeFi | Mass-scale dApps |

Tokenomics Comparison

Sui (Capped Supply)

10 billion max supply with allocations for:
- Community (50%)
- Team/Investors (34%)
- Storage fund (16%) → Deflationary mechanism

Aptos (Uncapped Inflation)

Decreasing annual issuance starting at 7%.
Transaction fee burns offset inflation.
Staking rewards drive participation.

Ecosystem Growth

Both chains excel in:

DeFi protocols (Aptos’ liquid staking vs. Sui’s deep liquidity pools)
NFT/gaming integrations
Enterprise adoption
