Overview

What is Matrix?

Matrix is an Unstoppable Execution Rollup built on top of BNB Chain L1, reconstructed with the Facet technology stack and deeply adapted to BNB’s PoSA consensus model. It fully relies on BNB for sequencing, data availability, and finality, while scaling ecosystem-wide throughput through an independent, high-performance execution environment. Matrix has no centralized sequencer, no multisig, and no admin controls, and it does not modify any consensus or protocol parameters of BNB. As long as BNB continues to run, Matrix cannot be halted, paused, or reset.

Why Matrix?

BNB Chain has become one of the world’s largest application-oriented blockchains, but as a single-chain state machine, its execution resources face inherent scalability limits:

• High-frequency DeFi, GameFi, and AI Agent workloads continuously increase execution pressure

• Network congestion leads to volatile gas fees and rising latency

• All applications compete for the same execution layer, making performance isolation impossible

• Raising the gas limit or modifying consensus parameters would affect all users and introduce unacceptable risk

Matrix provides BNB with a native, compatible, and governance-free scalability path by moving execution off-chain without altering consensus, delivering a 3–5× increase in effective execution throughput for the entire ecosystem.

Core Properties

Unstoppable Execution

Matrix processes inputs in a fully decentralized manner, with no sequencer, no committee, no multisig management, and no controllable switches. The Inbox is an ownerless EOA with no upgrade path and no pause capability — it operates solely based on BNB’s normal block production. Users can always submit calldata directly to the Inbox, meaning Matrix can only halt if BNB itself stops.

BNB-Secured Architecture

All of Matrix’s security comes directly from BNB: BNB determines ordering, carries the data, and provides finality, while Matrix simply executes that data. There is no additional validator set, no bridge administrator, and no new trust assumptions. Matrix security = BNB security.

Zero Modification to BNB

Matrix does not modify any underlying component of BNB:

• No BNB fork

• No parameter changes

• No DA expansion

• No new modules added

• No consensus upgrades or governance required

BNB can continue operating exactly as it does today, while Matrix provides scalability in a minimally coupled manner.

Execution-Only Rollup

BNB provides strong ordering and permanent data availability for all inputs. Matrix-node and Matrix-geth focus solely on executing these inputs, delivering a lightweight, efficient, and verifiable execution layer that scales independently.

What Matrix Enables

3–5× Throughput

Enabled by Matrix’s compact calldata encoding, zero-BNB transaction paradigm, and batched execution pipeline, BNB is able to accommodate substantially higher effective transactional throughput without incurring additional load on the underlying L1 infrastructure.

More Stable Gas Costs

Because execution load is handled within Matrix, gas volatility on the BNB main chain does not directly impact DApp performance, enabling a more stable and predictable fee curve.

High-Real-Time Execution Environment

Matrix is optimized for high-frequency workloads—such as DeFi bots, games, AI agents, and real-time data systems—providing a more predictable and lower-latency execution experience.

Full Compatibility with the Existing BNB Tooling

Matrix preserves full EVM compatibility, enabling developers to deploy applications without modifying any contracts or tooling. All user inputs are submitted to the Inbox as BNB L1 transactions (calldata), which ensures that:

• Wallets, RPC endpoints, and SDKs require no changes

• All BNB infrastructure components remain natively compatible

• No new blockchain needs to be introduced

Developers can immediately deploy existing DApps onto Matrix and directly benefit from higher throughput and a more stable, predictable execution environment.
