# Core Blockchain v1.2 InterLink Chain is structured across **four synchronized architectural layers**. Each layer addresses a distinct domain, and each builds upon the previous:
LayerNameCore Responsibility
Layer 0ZK-Biometric Identity NetworkVerified participant identity — protecting RWA integrity and AMM pools from bots and Sybil attacks
Layer 1High-Throughput Execution & Consensus EngineScalable EVM throughput, instant deterministic finality tuned for payment-grade settlement
Layer 2Native Economic Primitives (RWA Protocol)Protocol-embedded AMMs that automatically back digital assets with real-world transaction revenue; ITL as payment infrastructure & universal reserve
Layer 3Application & Integration LayerGasless UX via Smart Accounts, MDK super-app ecosystem, and Business Auth SDK
Before a transaction can execute at Layer 1, it must pass through the identity gate at Layer 0. Before a business asset gains market depth, the economic mechanics at Layer 2 must be active. And none of it matters at scale unless Layer 3 makes the entire experience transparent to the millions of businesses and participants who simply want to pay, own, and transact.
### Layer 0: ZK-Biometric Identity Network **Core Responsibility:** Verify that every participant interacting with RWA contracts and AMM pools is a unique, living individual — structurally eliminating bots, scripts, and duplicate accounts before any transaction reaches the execution layer. InterLink's ZK-Biometric Identity Layer performs on-device biometric verification within the device's Secure Enclave, generates a Zero-Knowledge Proof of uniqueness, and mints a singular, non-transferable **InterLink ID** — without ever exposing personal data. The full verification flow is detailed in **Unique Features**. This layer serves as the **protective infrastructure** for the entire RWA engine: * **AMM pool integrity** — Bots cannot obtain an InterLink ID, making protocol-embedded liquidity pools immune to MEV extraction. * **Fair RWA distribution** — Tokenized business dividends and airdrops reach verified holders, not bot farms. * **Payment infrastructure trust** — Transaction fee revenue flowing into AMM pools is guaranteed to represent genuine economic activity from verified participants. *** ### Layer 1: High-Throughput Execution & Consensus Engine **Core Responsibility:** Deliver the raw transaction throughput and instant finality required to serve as global payment infrastructure for tokenized businesses. #### High-Throughput EVM Execution Traditional blockchain networks execute transactions sequentially — each must complete before the next begins. Under load, this creates congestion that spikes fees and degrades user experience. For a payment infrastructure serving thousands of businesses and millions of daily transactions, sequential execution is structurally inadequate. InterLink Chain implements a **High-Throughput EVM** architecture purpose-built to minimize processing overhead and maximize validated transactions per block. Through optimized block pipeline design, state management, and transaction queuing, InterLink targets throughput levels capable of supporting mass-market payment volumes. **Full EVM compatibility is preserved:** standard Solidity contracts deploy without modification, and developers use familiar tooling (Hardhat, Foundry, MetaMask) without friction. Performance is entirely handled at the protocol level. | Metric | InterLink Chain | Ethereum Mainnet | Solana | | --------------------------- | ----------------------- | ---------------------------- | ---------------------------- | | **Target TPS** | 2,000 | \~15 | \~3,000 (variable) | | **Block Time** | \~3 seconds | \~12 seconds | \~0.4 seconds | | **Transaction Finality** | Instant (deterministic) | \~12 minutes (probabilistic) | \~13 seconds (probabilistic) | | **Average Gas Cost** | Near-zero | $2–$50 | \~$0.0025 | | **EVM Compatibility** | Full | Native | Partial (via bridge) | | **Native Sybil-Resistance** | Yes (ZK-Biometric) | No | No | > **Note:** TPS benchmarks reflect the design target for the InterLink Chain Mainnet. Network performance will be publicly verified during the Secure Mainnet phase (Q4 2026). #### Proprietary Consensus Engine: Deterministic Finality In traditional Proof-of-Work or standard block-producing networks, transactions are subject to "probabilistic finality" — users must wait for multiple block confirmations to ensure a transaction is not reorganized. InterLink Chain implements a **proprietary consensus engine** delivering **deterministic finality** within seconds. Operating initially on a deeply monitored Proof-of-Authority (POA) framework — then seamlessly transitioning into open, decentralized validator participation — the engine guarantees that once a transaction is validated, settlement is immediate and irrevocable. This is a non-negotiable requirement for payment infrastructure: a business cannot process a customer payment and wait 12 minutes for confirmation. The InterLink finality model mimics the speed of traditional credit card terminals while providing on-chain cryptographic proof. The consensus messaging and validator signature scheme are architecturally designed to integrate **post-quantum cryptographic algorithms**, ensuring the network's finality remains uncompromised by future quantum computing capabilities. *** ### Layer 2: Native Economic Primitives — The RWA Protocol **Core Responsibility:** Embed the automated liquidity and value capture mechanics that make ITL the payment infrastructure & universal reserve asset, and ensure every tokenized business has protocol-guaranteed market depth. This is the **economic heart** of InterLink Chain. Every other layer exists to support the mechanics described here. #### Protocol-Embedded Liquidity Pools In legacy ecosystems, AMMs (like Uniswap) are secondary DApps built on top of the network. Liquidity is fragmented, unreliable, and subject to third-party risk. InterLink radically breaks this convention by hardcoding liquidity mechanics directly into the base protocol. When an enterprise issues a tokenized representation of its business via the Transaction-Backed Digital Assets Protocol, the network **automatically instantiates** a foundational liquidity pool: * **Formula:** Constant product (`x · y = k`) * **Pairing:** Every RWA token is paired with **ITL** — the network's payment infrastructure & universal reserve currency. * **Depth:** Because liquidity is managed at the protocol level (not the DApp level), optimal trade routing and minimum slippage are computationally guaranteed. * **Sustainability:** Swap fees are automatically distributed to liquidity providers and the protocol revenue mechanism, fueling a self-sustaining liquidity cycle. #### Automated Value Capture Routing This is the economic engine that sustains the entire ecosystem. Rather than relying on speculative traders to support token prices, value capture is natively embedded in the transaction pipeline:
The result: a token whose market value is **mathematically tethered** to the business's real-world performance — not market hype. #### ITL as Payment Infrastructure & Settlement Layer Because every RWA token is structurally paired with ITL, the network establishes ITL as the **settlement currency** for the entire tokenized economy: * **Every new business tokenization** increases structural demand for ITL through the mandatory AMM pairing. * **Every transaction** routed through the payment infrastructure generates fee revenue that flows through ITL-denominated pools — this is the **exogenous value anchor** that prevents circular dependency. * **ITL is the unit of account** for all cross-asset settlement, creating a coherent price discovery mechanism across thousands of diverse business tokens. * **Cross-chain settlement** — InterLink's architecture is designed to support bridge protocols enabling ITL-denominated settlement from external blockchain ecosystems, positioning ITL as a cross-chain reserve asset for tokenized commerce. #### The Economic Flywheel The relationship between business adoption and ITL value is not circular — it is a **virtuous cycle with an exogenous anchor**: 1. **Businesses tokenize** on InterLink → creating ITL demand (AMM pairing) 2. **Customers transact** with businesses → generating fee revenue that flows into ITL pools 3. **Fee revenue** creates persistent buy-pressure on ITL → independent of market speculation 4. **Growing ITL liquidity** makes the platform more attractive for new businesses → attracting more tokenization The critical difference from reflexive models (e.g., Terra/LUNA): the demand for ITL is anchored by **real transaction fee revenue from productive businesses**, not by speculative peg arbitrage. If transaction volume grows, ITL demand grows. The anchor is economic activity — not market sentiment.
### Layer 3: Application & Integration Layer **Core Responsibility:** Make blockchain interaction as simple as using any Web2 app — so that millions of businesses and their customers can access, own, and trade digital assets without friction. #### Gasless Transactions via Smart Accounts In traditional public blockchains, every wallet must hold a volatile native asset to pay transaction fees. This is an invisible barrier that stops ordinary businesses and their customers from adopting Web3. On InterLink, wallets linked to verified InterLink IDs operate as **Smart Accounts**. A **Paymaster mechanism** built directly into the network allows any business — from a corner coffee shop to an enterprise — to sponsor transaction fees for their customers. Users interact, click, pay, and claim rewards without ever seeing a gas prompt. The experience is completely indistinguishable from a conventional mobile app. #### The InterLink Super-App Rather than forcing users to manage browser wallets and DApp URLs, InterLink places everything inside a single **InterLink App**: * Users access financial services, social platforms, games, and commerce in one unified environment. * Any developer or business owner can publish their storefront, service, or game as a **Mini-App** using the **Mini-App Development Kit (MDK)**. * The MDK handles user login, notifications, on-chain payments, and identity checks out of the box. #### The Business Auth SDK The **Business Auth SDK** extends InterLink's identity verification beyond the ecosystem. Any website or platform can integrate a "Login with InterLink ID" button that cryptographically guarantees the person behind the account is a verified, unique participant — eliminating fake accounts and bots at the point of authentication. A local restaurant running a loyalty program, an online store managing memberships, or a community forum moderating users can integrate this with a few lines of code — no blockchain expertise required.
