Solana Infrastructure Landscape

Orthogonal: Tower BFT (32 layers, 12.8s finality) vs Alpenglow (BLS aggregation, 100-150ms)

Solana's evolution from PoH + Tower BFT to BLS-aggregated vote certificates. 100x finality improvement.

Orthogonal: Ed25519 batching (65k+ sigs/sec) vs BLS aggregation (O(1) verification)

Current: Ed25519 batch verification. Future: BLS12-381 for vote aggregation. Performance-security tradeoffs.

Orthogonal: QUIC transport, Turbine propagation, kernel-bypass XDP

UDP-based QUIC for low latency, Turbine for block dissemination. Firedancer's XDP bypasses kernel for 20-30% latency reduction.

Orthogonal: RocksDB LSM (Agave) vs custom tile-based (Firedancer)

Accounts DB stores all on-chain state. Write amplification vs read latency tradeoffs. Snapshot and compaction strategies.

Orthogonal: Production validator client, majority network stake, proven reliability since genesis

Architecture: 610K LOC Rust, RocksDB storage, AVX2 signature verification, GPU-optional

Maintained by: Anza (formerly Solana Labs)

Orthogonal: 1M+ TPS via custom AVX512, kernel-bypass networking (XDP), modular tile architecture

Architecture: 651K LOC C, custom accounts DB, 18-28bp better rewards vs Agave

Stake: 20.9% network stake (Q1 2026), Jump Crypto

Orthogonal: MEV infrastructure, 94% network stake (2025), tip distribution to validators

Architecture: 627K LOC Rust (Agave fork), bundle execution, searcher-validator coordination

Revenue: MEV ≈0.2% of total staking rewards (Q4 2025)

Orthogonal: Cryptoeconomic performance guarantees via on-chain bonds (1 SOL per 10k stake)

Architecture: 24K LOC Rust, slashing-free design, automatic underperformance compensation

Use case: Marinade Protected Staking Rewards, validator trust signaling

Orthogonal: Sub-50ms real-time validator monitoring via Geyser plugin streaming

Architecture: gRPC subscriptions (accounts, blocks, transactions), production RPC providers

Providers: Helius (99.99% uptime), Triton One (~100ms latency)

Orthogonal: Verify 65k+ signatures/sec to sustain high TPS, critical bottleneck

Implementations: Agave (AVX2, ~40k/core), Firedancer (AVX512, ~100k/core), Jito (Agave fork)

Deep dive: Batch verification algorithm, SIMD optimization, GPU acceleration, divide-and-conquer on failure

Orthogonal: UDP-based multiplexed streams, 0-RTT connection, low-latency validator networking

Implementations: Agave (quinn library), Firedancer (kernel-bypass XDP), standard vs custom

Deep dive: QUIC protocol, stream multiplexing, congestion control, kernel-bypass advantages (20-30% latency reduction)

Orthogonal: Store all on-chain account state, high write throughput + fast reads required

Implementations: Agave (RocksDB LSM tree), Firedancer (tile-based memory-mapped), trade-offs

Deep dive: Storage format, indexing, snapshots, compaction, Geyser integration, write amplification analysis

Planned: Tower BFT vs Alpenglow, Turbine block propagation, Vote verification, Geyser plugins, MEV infrastructure, PoH verification, Snapshot mechanisms, Stake delegation mechanics

Status: Research in progress, 9 agents running in parallel
