Intro

Tensora is an AI-specialized Layer 2 blockchain built on BNB Chain using the OP Stack. It combines Ethereum Virtual Machine compatibility with a decentralized AI inference marketplace inspired by Bittensor's subnet model. Tensora enables developers to deploy smart contracts that natively interact with AI models while paying gas fees in TORA tokens via ERC-4337 account abstraction.

What Makes Tensora Different

Traditional L2s focus on scaling generic computation. Tensora adds a protocol layer for competitive AI markets called subnets. Miners run inference models, validators score outputs, and the chain distributes rewards based on quality. This creates an economic incentive for accurate AI services without relying on centralized APIs.

Unlike Bittensor, which uses a custom blockchain, Tensora runs on the EVM. Developers use Solidity, Hardhat, and Foundry. Existing Ethereum tooling works without modification. The bridge to BNB Chain uses the battle-tested OP Stack standard bridge.

Key Design Decisions

BNB as Native Gas: The L2 VM uses BNB internally for gas accounting. This simplifies OP Stack integration. Users never hold BNB directly; the Paymaster contract converts TORA to BNB on their behalf.

OP Stack Over Custom Chain: Inherits Ethereum's security model, tooling, and bridge infrastructure. Upgrades flow from Optimism's audited codebase.

Calldata DA on BSC: Cheaper than Ethereum mainnet calldata. Sufficient for AI inference workloads. Future migrations to BNB Greenfield or EigenDA remain possible.

Bittensor Model, EVM Native: Tensora replicates Bittensor's incentive structure—miners compete on quality, validators stake and score, rewards follow Yuma consensus—but inside Solidity smart contracts. No custom chain client required.

Who Should Use Tensora

• AI developers who want decentralized inference without Web2 API dependencies

• DeFi protocols integrating ML models for risk scoring or prediction markets

• dApp builders seeking low-cost transactions with built-in AI capabilities

• Miners and validators earning TORA by running models and scoring outputs
