Aptos Orderless Wev

Aptos Orderless WEV Skill

Trit: +1 (PLUS) - Generative parallel execution

World Extractable Value via Aptos orderless transactions with Strong Parallelism Invariance (SPI) guarantees and GF(3) conservation.

Core Concept

WEV (World Extractable Value) exploits knowledge differentials between domains in orderless execution systems. Unlike MEV (order-dependent extraction), WEV leverages parallel execution invariance.

Aptos Orderless Transactions (AIP-123)

From Aptos Documentation:

• Purpose: Execute transactions out of order for multi-machine signing
• Replay Protection: Uses replayProtectionNonce (random u64)
• Max Expiration: 60 seconds
• Block-STM: Parallel execution engine

// Orderless transaction structure
interface OrderlessTransaction {
  replayProtectionNonce: bigint;  // Random u64 for replay protection
  payload: TransactionPayloadPayload;  // AIP-129 payload
  expirationTimestamp: number;  // Max 60 seconds
}

GF(3) Conservation as Orderless Guarantee

For any valid WEV transaction triplet, the sum of trits must be zero:

PLUS  (+1): Generators (A, B, C, D, E, W, X, Y, Z)
ERGODIC(0): Coordinators (F, G, H, I, J, K, L, M)
MINUS (-1): Validators (N, O, P, Q, R, S, T, U, V)

Sum: 9(+1) + 8(0) + 9(-1) = 0 ✓

WEV Triplet Structure

(defn wev-triplet [from-world to-world mediator]
  (let [trits [(world-trit from-world)   ; PLUS (+1) sender
               (world-trit mediator)      ; ERGODIC (0) coordinator
               (world-trit to-world)]]    ; MINUS (-1) validator
    (assert (zero? (mod (reduce + trits) 3))
            "GF(3) conservation violated!")
    {:transactions [from-world mediator to-world]
     :orderless true
     :conserved true}))

Strong Parallelism Invariance (SPI)

SPI Theorem: For any deterministic generator G with seed s,
             ∀ permutation π of indices I:
             G(s, I) ≡ G(s, π(I)) (modulo ordering)

Verification:

• ordered == reversed == shuffled
• parallel == sequential
• GF(3) sum preserved across all orderings

Open Games Formalization

Orderless Game as Open Game

data OrderlessGame s t a b = OrderlessGame
  { play    :: s -> a                    -- Forward: knowledge state → action
  , coplay  :: s -> b -> t               -- Backward: observation → utility
  , nonce   :: Word64                    -- Replay protection
  , triplet :: (World, World, World)     -- GF(3)-balanced worlds
  }

-- Composition is order-invariant
instance Category OrderlessGame where
  (.) g h = OrderlessGame
    { play = play g . play h
    , coplay = \s b -> coplay h s (coplay g (play h s) b)
    , nonce = xor (nonce g) (nonce h)  -- Combined nonce
    , triplet = mergeTriplets (triplet g) (triplet h)
    }

Epistemic Arbitrage as Nash Equilibrium

-- Knowledge differential game
epistemicArbitrage :: OpenGame KnowledgeState KnowledgeState Action Utility
epistemicArbitrage = OpenGame
  { play = \k -> 
      let diff = knowledgeDifferential k
      in if profitable diff then ExtractWEV else Wait
  , coplay = \k a -> 
      case a of
        ExtractWEV -> k { value = value k + wevProfit }
        Wait -> k
  , equilibrium = \k -> 
      -- Nash: extract iff differential profitable
      profitable (knowledgeDifferential k) == (play k == ExtractWEV)
  }

Mediator Selection Logic

(defn find-mediator [worlds from-world to-world]
  (let [from-trit (get-in worlds [from-world :trit])
        to-trit (get-in worlds [to-world :trit])
        sum-mod3 (mod (+ from-trit to-trit) 3)
        needed-trit (case sum-mod3
                      0  0    ; need 0 to make sum 0
                      1 -1    ; need -1: (1 + (-1) = 0)
                      2  1)]  ; need +1: (2 + 1 = 3 ≡ 0)
    (first (filter #(= needed-trit (get-in worlds [% :trit]))
                   (keys worlds)))))
