Mantle is the first modular Ethereum L2 solution to completely reimagine the interplay between a blockchain's many moving parts, including data availability, greater performance, security, and more. Its inception and proposal date back to June 2022. Mantle is a language layer 2 (L2) that is compatible with the Ethereum Virtual Machine (EVM), allowing developers to use Ethereum's smart contracts and tools with minimum modification. Mantle uses optimistic rollups and an enhanced data availability solution in its modular design. Through the use of optimistic rollups, both computation and state storage may be moved off-chain. By reducing the amount of computation that must be sent and processed on the Ethereum Mainnet, Mantle's throughput may be increased at a reduced cost.

BitDAO is one of the largest decentralized autonomous organizations (DAO) in the world. The Mantle network will carry on BitDAO's mission to increase web3's global acceptance by making it easier for consumers and developers to join the network. Mantle will employ BIT tokens for its transaction processing, project facilitation, and stakeholder rewards. The whole BitDAO community and ecosystem fully supports Mantle as the first Ethereum layer-2 controlled by a DAO. With its low fees and clever architecture, Mantle is the next step toward a decentralized future.

While these scaling solutions boast of the potential to increase the capacity of the Ethereum network, they frequently come at the expense of security and integrity. To avoid having their own security compromised, decentralized protocols that handle high volumes of liquidity cannot be deployed on these chains. Hyperscalability on the Ethereum network is made possible by Mantle, which employs roll-up technology and a decentralized data availability layer to boost efficiency and speed while decreasing costs and latency. Mantle's unrivaled security comes in the form of an Ethereum roll-up technology built inside a user- and developer-friendly EVM environment.

Modular Data Availability on Mantle can boost transaction throughput beyond existing L2 systems, while also decreasing processing needs and improving decentralization without compromising security. Mantle considerably minimizes the trust risk of L2 execution outcomes through the use of Multi-Party Computation (MPC). The challenge period for withdrawals can be reduced thanks to Threshold Signature Scheme (TSS) technology, which increases confidence in off-chain transaction execution outcomes. To solve the problems of network censorship and single-point failure, Mantle employs a Decentralized Sequencer to promote safe and trustless block generation.

Mantle is a technological stack that leverages, and to scale Ethereum without sacrificing web3 requirements.

Functions such as Mantle's execution, consensus, settlement, and data availability are handled by distinct layers that may be operated by various players in the network. Mantle saves a lot of money on gas and gains performance as a consequence. The trilemma between scalability, security, and decentralization in blockchain technology is resolved by this. Instead of only complete node validators on layer-1, all users now benefit from the enhanced security. Technology like fraud proofs and ZK proofs can lower the total execution and validation burden on the nodes since they do not need to execute all the transactions for validity checking if they operate on their own layers.

To ensure data availability at the layer-2 level, Ethereum's current trust network is used via the re-staking protocol EigenLayer. However, the same high standard of security that underpins Ethereum's Mainnet is also applied here. That's why Mantle takes advantage of EigenLayer's EigenDA solution for data availability so that nodes on the Mantle network may provide those services. Using BIT staking, validators may offer their services and participate in Mantle's economic model, which in yield creates new revenue streams. These then add to the fullness and precision of block data in Mantle's execution layer. Since EigenDA compartmentalizes the two, data availability and consensus may be handled independently. It also keeps an erasure rate such that whole block data may be rebuilt from block data fragments from both layer-2 and layer-1 sources, and it includes a unicast channel for data exchange between network members to maximize efficiency in data storage and transmission. The high throughput required by web3 applications of the future would be provided by such a system, and the staking value of BIT would expand in tandem with its governance features.

Only one Sequencer is managed by the core team of the rollup in the classic optimistic rollup paradigm. A "soft confirmation" is immediately sent to the user when their transaction is registered on layer-1. Despite appearances, having only one group responsible for running the Sequencer introduces a potential for serious mistakes. This creates a security issue since only the Sequencer may submit transaction bundles to the layer-1 contract with priority write access to the layer-2 network. The Sequencer is decentralized in Mantle, allowing for anybody can join the permissionless set of layer-2 block creators.

In the optimistic model, rollups depend on their network's players to behave ethically. Therefore, the network's security must be improved by the careful deployment of fraud proofs. Of course, there will be difficulties along the way. The current state of the on-chain verifier can only execute instructions in a low-level virtual computer. In other words, it is not always the case that the contents of the fraud proof come straight from a compliant EVM client. Still, even if it is, the on-chain verifier is effectively oblivious to the source of the fraud proof, thus there is no way to prove it. Consequently, this disrupts the Ethereum client's built-in mechanism for trust reduction. To address this problem, Mantle adopts a strategy that compiles and verifies fraud proofs directly using EVM instructions, allowing all Ethereum clients to communicate with a unified proof system in a transparent manner. As a result, verifiers, compilers, and clients can have as little trust in each other as possible.

When a user of a wallet, a decentralized application (DApp), or a script begins transferring cash or carrying out an operation, the transaction is introduced to the Mantle network for the first time. A request may be crafted, signed with private keys, and delivered to the Mantle network for Sequencer processing using the available tools, including the integrated Mantle SDK. Mantle's ability to generate low transaction fees is due to the fact that the fixed expenses are spread across several transactions within a batch of pending blocks. After this, the MPC nodes do further checks on the block data before broadcasting it to the Ethereum network through Sequencer, where it will be received by the various participants on Mantle and Ethereum. While on Ethereum the communicated data is recorded on-chain after going via Ethereum's consensus mechanism, rollup verifiers on Mantle will synchronize the data to make it accessible for other users and DApps. The data will also be synchronized and made available with the help of the Data Availability nodes on Mantle. These nodes will be rewarded with BIT tokens for their efforts.

ETH and other tokens can't simply be moved between Mantle (layer 2) and Ethereum (layer 1) without a bridge between the two blockchains.

On addition of its present use as the DAO's governance token, BIT tokens will be used by Mantle as part of the BitDAO effort for gas costs, staking, and other ecosystem services. With this, the BIT token's utility may expand exponentially, driving up both demand and token usage. By using BitDAO's native token BIT as a universal currency for all developments, both established and emerging communities will be able to reinforce and contribute to the extension of the Mantle network while reaping financial benefits in return. Utilizing BitDAO's preexisting partner ecosystem, developers and consumers may employ Mantle's blockchain to power web3 apps and functionalities.

As of November 30th, 2022, BitDAO has announced the official soft launch of Mantle. The public Mantle testnet launched on January 10, 2023. The Mantle team plans to release the mainnet in Q2/Q3 of 2023, and there will be a substantial incentive scheme for developers when the mainnet is released.

There are a lot of layer-2 solutions available now, but what makes Mantle stand out is its focus on addressing problems that other solutions have ignored. It has the potential to transform the web3 ecosystem and deliver a more scalable and secure solution because to its modular Data Availability, Multi-Party Computation, and Decentralized Sequencer capabilities.
