Understanding Midgard L2

Optimistic Rollups: The Core Technology

Optimistic rollups are a cutting-edge scaling solution that processes transactions off-chain, reducing the computational load on the main blockchain. By assuming transactions are valid by default and only verifying them if a fraud proof is submitted, optimistic rollups significantly increase throughput and efficiency.

Seamless Integration with Cardano

Midgard seamlessly integrates with Cardano’s Layer 1 (L1) blockchain. It uses smart contracts to manage state transitions and employs Merkle roots for efficient proof submissions, ensuring that off-chain transactions are secure and verifiable.

Key Features

Explore how does Midgard ensure high transaction throughput while maintaining the robust security and decentralization of Cardano L

Validator Network

Validators play a crucial role in the Midgard protocol. They are responsible for processing transactions off-chain and submitting state updates to the Cardano blockchain. Validators post bonds to ensure their commitment to honest behavior, and their activities are continuously monitored through fraud proofs.

State Management

Midgard maintains a compact and efficient record of the current state, incoming transactions, and next state using Merkle roots. This structure allows for fast and secure transaction processing without overburdening the Cardano network.

Fraud Proof System

The integrity of Midgard is upheld by a robust fraud proof system. During a designated challenge period, participants can contest state updates by submitting fraud proofs. This system ensures that any fraudulent or incorrect state transitions are quickly identified and rectified.

Economic Incentives

To maintain the security and efficiency of the protocol, Midgard employs economic incentives. Validators who act dishonestly risk losing their bonds, while challengers who submit valid fraud proofs are rewarded, ensuring a high level of integrity within the network.

How It Works

At our AI software company, we prioritize meaningful impact and collaboration with like-minded companies. We focus on delivering value, not chasing sales targets.

Transaction Processing

Transactions are initially processed off-chain by validators, who then submit state updates to the L1 State Validator contract on Cardano.

State Commitments

Validators regularly publish state commitments that include the current state, incoming transactions, and the next state, represented in a compact form using Merkle roots.

Fraud Proofs

During a designated challenge period, any participant can contest the validity of state updates by submitting fraud proofs. These proofs demonstrate the invalidity of a state transition, ensuring that any fraudulent activity is quickly identified and rectified.

Economic Incentives

Validators are incentivized to behave honestly through a bonding mechanism, while challengers who successfully submit fraud proofs are rewarded.

Benefits of Midgard L2

Enhanced Scalability

Midgard significantly increases Cardano's transaction throughput, making it capable of supporting a wide range of decentralized applications and services without compromising on performance.

Lower Transaction Costs

By processing transactions off-chain, Midgard reduces the overall cost of transactions, making Cardano more accessible and cost-effective for users.

Robust Security

The combination of optimistic rollups, fraud proofs, and economic incentives ensures that Midgard maintains the high-security standards of the Cardano blockchain, protecting users and their assets.

Get Involved

Whether you’re a developer, SPO, or simply a blockchain enthusiast, Midgard L2 offers numerous opportunities to participate and contribute. Join us in pushing the boundaries of what Cardano can achieve.

Optimistic Rollups

Midgard uses optimistic rollup technology, which assumes transactions are valid by default and only checks them if a fraud proof is submitted. This reduces the computational load on the main blockchain and improves overall efficiency.

Robust Validator Management

The protocol includes a comprehensive validator management system where validators post bonds to ensure honest behavior. Fraud proofs submitted by challengers help maintain the integrity of the system.
