Mantle Network is a Layer-2 scaling solution compatible with Ethereum Virtual Machine (EVM). It employs Optimistic rollups to enable swift and cost-effective transactions. By processing transactions off-chain and settling them on-chain, Mantle Network ensures efficiency while utilizing Ethereum's capabilities. ^[1]

Overview

Mantle Network focuses on developing a scaling solution compatible with Ethereum's ecosystem, ensuring seamless interoperability for existing contracts and tools with minimal adjustments. Leveraging its modular architecture, Mantle Network integrates an optimistic rollup mechanism with innovative data availability solutions, enhancing accessibility and affordability while maintaining Ethereum's security standards. ^[1]

The protocol design emphasizes enhancing user experience by reducing costs and improving usability, simplifying developer development processes, and providing a robust infrastructure for the emerging generation of decentralized applications (dApps). By adopting a rollup structure, Mantle Network harnesses Ethereum's validators and consensus protocols to significantly diminish gas fees, decrease transaction latency, and augment throughput. Users have the flexibility to tailor transaction confirmation requirements, enabling near real-time confirmation with optimized security parameters. ^[1]

Mantle Network's modular architecture segregates transaction execution, consensus, settlement, and storage functions into distinct modules within the chain. This includes an EVM-compatible execution layer for transaction processing, a consensus and settlement layer executed on Ethereum's platform, and an external data availability component, currently Mantle DA powered by EigenDA technology. ^[1]

History

The Mantle Network, initiated in July 2023, was the first Layer-2 solution launched by a DAO. Originating from BitDAO, known for its substantial treasury in the crypto realm, the network underwent consolidation with Mantle following a community vote in May 2023. This merger led to the rebranding of BitDAO as 'Mantle Governance,' with all BIT tokens converted to MNT tokens at a 1:1 ratio in June 2023. ^[2]

Features

Modular Blockchain Rollups

Mantle Network implements a layered approach to its execution, consensus, settlement, and data availability functions, allowing different network actors to manage specialized layers. This architectural design enables Mantle Network to achieve notable reductions in gas costs and overall performance enhancements. ^[3]

Employing a Modular Rollup model, Mantle Network optimizes fundamental blockchain operations, addressing a significant challenge in the blockchain community: the Scalability, Security, and Decentralization trilemma. ^[3]

The segregation of resources enhances network efficiency by allocating specific tasks to each layer, ensuring that all users benefit from improved security, unlike the reliance solely on full node validators in Layer-1 (L1). Operating on separate layers alleviates the execution and validation burden on nodes, as technologies like fraud proofs and ZK proofs no longer require them to execute all transactions for validity checks. ^[3]

Data Availability

Mantle Network addresses security concerns inherent in rollup architecture by leveraging EigenLayer, a re-staking protocol. EigenLayer utilizes Ethereum's trusted network to ensure data availability for Layer-2 solutions while maintaining security levels akin to the Ethereum Mainnet. Through EigenLayer's data availability solution, known as EigenDA, Mantle Network enables nodes to furnish data availability services. Validators engage in Mantle Network's economic model by staking $MNT tokens, unlocking additional yield prospects. This participation enhances block data completeness and accuracy within Mantle Network's execution layer. ^[3]

EigenDA separates the data availability from the consensus layer and implements a unicast channel for efficient data storage and transmission among network participants. It also maintains an erasure rate, facilitating complete block data reconstruction through data pieces from both Layer-2 and Layer-1 sources. This solution enhances the utility of $MNT beyond governance functions, offering increased staking opportunities while furnishing the requisite high throughput for next-generation Web3 applications. ^[3]

Fraud Proofs

In the optimistic model embraced by rollups, trust in network participants' good behavior is assumed, necessitating robust fraud proofs implementation to fortify network integrity. However, implementing fraud proofs poses challenges. ^[3]

Currently, the on-chain verifier can only execute instructions in a lower-level virtual machine, requiring fraud proofs to be translated into this language by EVM clients. Consequently, the content of fraud proofs is often not directly obtained from compliant EVM clients, and there are no means of verifying their source, as the on-chain verifier lacks visibility of the fraud proof producer. This hampers trust minimization embedded in Ethereum clients. ^[3]

Mantle Network tackles this issue by adopting an approach that directly compiles and verifies fraud proofs using EVM instructions. This allows all Ethereum clients to openly interact with a shared proof system, reducing trust assumptions among verifiers, compilers, and clients. ^[3]

Transaction Lifecycle

Transactions within Mantle Network begin when initiated by a wallet user, dApp, or script. Tools like Mantle SDK facilitate request creation, signing, and submission for Sequencer processing. Upon verification, transactions are added to pending blocks, leveraging batch processing to distribute fixed costs and minimize transaction fees. ^[3]

Subsequently, Threshold Signature Scheme nodes verify block data before transmission to the Ethereum network through Sequencer. Rollup verifiers synchronize data within the Mantle Network for accessibility by users and dApps, while Ethereum records transmitted data on-chain via its consensus mechanism. Moreover, Data Availability nodes synchronize and ensure data access within the Mantle Network, earning $MNT tokens as rewards. ^[3]

$MNT Token

The $MNT tokens fulfill dual roles within the Mantle Ecosystem, serving as governance and utility tokens. In governance, each $MNT token carries an equal weight in voting rights, allowing token holders to engage in DAO decision-making processes. As a utility token, $MNT is utilized to cover gas fees on the Mantle Network and can also serve as collateral for Mantle Network nodes. Operating as an ERC-20 token, $MNT shares comparable functionality with other Layer-2 blockchain tokens. ^[3]

Tokenomics

The initial distribution of Mantle (MNT) tokens was as follows: ^[4]

• 49.00% is allocated to Treasury
• 51.00% is allocated to Circulating

Citizens of Mantle

Becoming a Citizen of Mantle provides individuals access to an immersive experience within the Mantle Ecosystem. A Citizen of Mantle NFT avatar is a faithful companion on a journey of building, connecting, playing, earning, and trading within the Mantle network. As users achieve milestones within the Mantle Ecosystem, their NFT avatars will evolve, gaining various traits. These avatars reflect the engagement and accomplishments within the Mantle Ecosystem, unlocking future benefits and opportunities as participants progress. ^[5]

Mantle LSP

Mantle Liquid Staking Protocol (LSP) operates as a permissionless and non-custodial ETH liquid staking protocol deployed on Ethereum L1 and governed by Mantle. It features a simple and modern design coupled with robust risk management measures, drawing on Mantle Ecosystem resources to offer a rewarding experience and bolster Mantle's yield potential. Mantle Staked Ether ($mETH) functions as the value-accumulating receipt token within Mantle LSP, facilitating the pooling of ETH deposits from stakers. Stakers receive $mETH tokens representing their claim to the staked principal and accrued rewards, which can be utilized in other applications. Upon unstaking, stakers receive their staked ETH and any rewards earned during the staking period, including issuance, priority fees, and maximal extractible value (MEV), distributed among stakers, LSP, and node operators. ^[6]
