SEU-Solana · Zero-Overhead Runtime for Agent Economies

State Execution Unit powered by the u64se engine · Bare-Metal 5-Byte Wire, Branchless ALU, 108x Parallel Packing

As autonomous trading agents, liquidation bots, and decentralized orderbooks scale on Solana, dynamic Borsh serialization imposes a severe compute ceiling. This proposal presents SEU-Solana: zero-heap register-mapped architectures with pure ALU core execution (~8 CU) within deterministic 340 CU instruction step transitions live on Solana Devnet.

Comparative Execution Surfaces Standard Borsh vs Deterministic Register Machine
Dynamic Borsh & Macro State Model
Anchor and Borsh frameworks decode data by traversing byte streams on the heap. Multiple nested conditionals generate branch-heavy SBF bytecode, causing unpredictable latency jitter under network congestion
Average Compute Cost
2,400 — 6,800 CU
Zero-Heap Register Execution Unit
Direct pointer casting into aligned memory slices. Arithmetic masks validate state bounds without conditional jumps, guaranteeing flat O(1) latency and eliminating heap fragmentation
Deterministic Cost
<1,900 CU (Step: 340 CU · ALU Core: ~8 CU)
Dynamic Compute Unit Clamping & Sealevel Economics The 1,850 CU Mathematical Envelope · 108x Block Density
Theorem & Equation · Dynamic Clamping
Why 1,850 CU? The Envelope Equation
Solana transactions default to reserving 200,000 CU if unconstrained. The State Execution Unit dynamically clamps its execution budget using the exact linear envelope:
L(H) = C_runtime + H × C_step + Δ_slack envelope
C_run = 850 (Auth) + 120 (Clock) + 440 (Wire) ≈ 1,410 CU
L(1) = 1,410 (Base) + 340 (Step) + 100 (Slack) 1,850 CU
C_step = 332 (Dispatch & Boundary) + 8 (Pure ALU Core) 340 CU
ALU = Branchless 64-Bit Register Bitmask ~8 CU
L(1) = 1,850 CU Step = 340 CU ALU Core = ~8 CU Slack = 100 CU
Validator Scheduler · 99.08% Lock Reduction
Dynamic vs Static Sealevel Scheduling
Solana blocks cap total compute at 48,000,000 CU. Unconstrained programs lock 200,000 CU per transaction, limiting a block to only 240 transactions
Default : 48,000,000 CU / 200,000 CU (Anchor) 240 tx / blk
u64se (SEU) : 48,000,000 CU / 1,850 CU (Clamped) 25,945 tx / blk
Density = 25,945 tx / 240 tx (Block Packing) 108.1× Gain
Locks = 1 - (1,850 CU / 200,000 CU) 99.08% Freed
108x Density 99.08% Lock Drop Zero Fee Waste

64-Bit State Atom Zero-Heap Register Allocation

Traditional Solana programs allocate dynamic vector buffers on the heap to deserialize accounts. The SEU-Solana runtime eliminates heap allocations entirely (no_allocator!()). The state is packed into a compact 64-bit transparent integer register
