About Radius

What is Radius?

Radius is a trustless shared sequencing layer that offers sequencing-as-a-service and cross-rollup interoperability solutions for rollups. Rollups are specialized blockchains that move executions off-chain to enhance transaction processing speed and overall blockchain performance.
Validators and sequencers play a critical role in the sequencing and block-building process in the current blockchain landscape. However, they also have the ability to censor and extract MEV (Miner Extractable Value), which has resulted in significant financial losses for users in recent years.
Radius addresses this issue by implementing a zero-knowledge cryptographic solution that prioritizes user protection from harmful MEV and censorship. This ensures that the sequencing process is free from any malicious activities, providing a safer and more secure environment for users. Additionally, rollups can generate profits through atomic cross-rollup transactions, facilitated by an open marketplace for profit-seeking traders. This creates a unique revenue stream for rollups and contributes to the overall expansion of the ecosystem.

Why Radius?

Radius offers unique benefits for rollups while simplifying their deployment in a modular fashion:
  1. 1.
    Protection Against Harmful MEV and Censorship: Radius provides user protection against censorship and harmful MEV through encryption features and zero-knowledge. This creates a secure and reliable environment for end-users, particularly high-volume traders.
  2. 2.
    Profitability through Cross-Rollup Transactions: Rollups earn profits through atomic cross-rollup transactions such as arbitrage, liquidation, and backruns, which are captured by traders and searchers through an open marketplace. This improves the price stability and capital efficiency throughout the rollup ecosystem as profit-seekers compete through auctions.
  3. 3.
    Single Sequencer for Maximum Scalability: Radius helps rollups achieve their maximum scalability potential by using a single sequencer elected every epoch. This eliminates the need for consensus mechanisms that often come with performance tradeoffs over a single sequencer. To address the risks of a centralized sequencer, Radius uses a zero-knowledge cryptographic solution called PVDE to eliminate the need for trust in sequencing.
