Layer 2 Architecture

Trayon is a decentralized Layer 2 built with Polygon CDK (Chain Development Kit), optimized for high-availability data capture and validation, real-time AI oracle processing, and low-cost transactions secured by Ethereum through ZK-proofs.

The layered stack

The protocol is organized into four layers, top to bottom:

┌─────────────────────────────────────────────────┐
│  Application Layer                              │
│  GovTech · Corporate · Judicial · Markets       │
└────────────────┬────────────────────────────────┘
                  │
┌─────────────────▼───────────────────────────────┐
│  Trayon Smart Contracts (Solidity)               │
│  Oracle Manager · Validator Registry · TRAY      │
└─────────────────┬───────────────────────────────┘
                  │
┌─────────────────▼───────────────────────────────┐
│  Trayon Layer 2 (Polygon CDK)                    │
│  Sequencer · EVM State Machine · AI Consensus    │
└─────────────────┬───────────────────────────────┘
                  │
┌─────────────────▼───────────────────────────────┐

│  ZK-SNARK Proofs · Batches to Ethereum/Polygon   │
└─────────────────────────────────────────────────┘

Sequencer node

The sequencer orders incoming transactions, builds batches (capped at 2,000 transactions per batch), computes the resulting state root, and coordinates the consensus round with validators before finalizing a block.

Mempool Manager → Block Producer → Consensus Coordinator → Settlement & ZK Proving
   (order, fee)     (batch, root)     (broadcast, quorum)     (proof, L1 batch)

Validator node

Each validator runs an EVM-compatible state machine, a consensus handler, a stake manager with slashing logic, and an AI processing pipeline that independently verifies proposed data before signing off with a BLS partial signature.

Settlement to Ethereum

Batches are proven with ZK-SNARKs and submitted to Ethereum L1 through Polygon CDK, inheriting Ethereum's security guarantees while keeping transaction costs low and throughput high on Layer 2.

TRAY as the native gas token

TRAY completely replaces ETH as the gas currency inside the Trayon Layer 2. Every transaction — a validated data submission, an oracle query, a governance vote — is metered and paid in TRAY:

Transaction on Trayon L2:
  gasPrice = 10 wei (TRAY)
  gasLimit = 21,000
  fee      = 210,000 TRAY (paid entirely in TRAY, no ETH required)

This removes the friction of holding a separate gas asset — a government agency or auditing firm can transact on Trayon without ever touching ETH — and ties gas demand directly to TRAY's deflationary fee-burn mechanics (see Fee burn & deflation).

// Simplified custom gas token settlement (Polygon CDK)
contract GasToken is ERC20 {
    address public sequencer;

    function payGas(uint256 amount) external {
        require(balanceOf(msg.sender) >= amount, "insufficient TRAY");
        burn(amount);
        emit GasConsumed(msg.sender, amount);
    }
}

Validator node internals

A full validator is more than a single process — it combines state sync, stake management, and AI-assisted verification into one node:

Recommended hardware

ResourceRecommended
CPU16-core (8-core minimum — see Running a Validator)
RAM32 GB
Storage500 GB+ SSD (1 TB NVMe recommended for archive mode)
Network99%+ uptime, <100ms latency to peers

End-to-end validation lifecycle

1. Data ingestion
   AI agents capture data from official APIs (JSON, CSV, HTTP)

2. Consensus phase
   Each validator independently executes the verification algorithm;
   Threshold Signature Scheme requires 2/3+1 agreement; 12s block timeout

3. Commit to blockchain
   Merkle root of validated data + aggregated BLS signature,
   stored via the TrayonOracle smart contract

4. ZK-proof generation
   Sequencer batches state transitions and proves them with a
   ZK-SNARK before submitting to Ethereum L1 via Polygon CDK
See Consensus for the full round timing and slashing conditions, and Oracle & AI Validation for how data is verified before it reaches the sequencer.
