Understanding Layer 2 Solutions

Midgard L2 is the pioneering optimistic rollup protocol designed to enhance the scalability of the Cardano blockchain. By leveraging advanced Layer 2 technology, Midgard ensures high transaction throughput while maintaining the robust security and decentralization of Cardano’s Layer 1

1. The Need for Layer 2

As blockchain networks grow in popularity and usage, they often face scalability challenges. High transaction volumes can lead to network congestion, resulting in slower transaction times and higher fees. Layer 2 solutions aim to alleviate these issues by enabling faster, cheaper, and more scalable transactions.

2. How Layer 2 Works

Layer 2 solutions operate on top of the main blockchain, or Layer 1, but execute transactions off-chain. This means that while the primary blockchain remains secure and decentralized, the transaction processing happens off-chain, leading to increased throughput and reduced costs.

Types of Layer 2 Solutions

Optimistic Rollups

Optimistic rollups assume transactions are valid by default and only verify them if a fraud proof is submitted. This reduces the need for immediate on-chain computation, significantly increasing transaction throughput and efficiency. Midgard L2, for example, utilizes optimistic rollups to scale the Cardano blockchain effectively.

State Channels

State channels allow users to conduct multiple transactions off-chain, with only the final state being recorded on the main blockchain. This reduces the number of on-chain transactions, leading to faster and cheaper operations.

Sidechains

Sidechains are independent blockchains that run parallel to the main blockchain. They allow for assets to be transferred between the main chain and the sidechain, enabling complex operations and applications without burdening the primary network.

Plasma

Plasma chains are smaller, more efficient blockchains that run alongside the main blockchain. They process transactions independently and periodically submit proofs to the main chain, ensuring security and integrity while reducing the load on the primary network.
