1. Introduction

1.1 Status Network and Linea Integration

Status Network aims to introduce gasless transactions at scale. To achieve this, SN will integrate the gasless module directly into the Linea stack rather than creating a separate fork. Using Linea's existing architecture and plugin system reduces maintenance and aligns SN closely with ongoing Linea developments. This setup prevents ecosystem fragmentation by positioning SN as a collaborative extension of Linea.

The key component of this gasless approach is Vac's Rate Limiting Nullifier, which permits transaction rate limitation without the need for traditional gas fees. The document describes the architecture and integration elements needed to safely enable gasless transactions.

1.2 RLN

RLN is a zero-knowledge system designed to prevent spam without compromising user privacy unless a violation occurs. It replaces traditional gas fees with cryptographic rate limits enforced via ZKPs and Shamir's Secret Sharing.

RLN characteristics:

• Zero-Knowledge Proofs: Users generate ZKPs verifying their RLN group membership without revealing their identity. The group membership indicates the maximum gasless transaction throughput for each tier.
• Shamir's Secret Sharing and Nullifiers: Users hold a secret key used to generate unique nullifiers for transactions. If a user exceeds their transaction limit within an epoch (e.g., block or timestamp), their secret key becomes recoverable, exposing them.
• Spam Detection: Users exceeding limits effectively reveal their secret, leading to penalties like Deny List inclusion, higher future gas costs, or potential token slashing.

2. System Overview

2.1 User Onboarding and Karma

Users earn Karma, a non-transferable, soulbound token, through actions benefiting the network:

• Bridging whitelisted yield-bearing assets (ETH and DAI initially)
• Staking SNT tokens
• Interacting with whitelisted Status Network apps
• Paying premium gas fees or donating to the public funding pool
• Participating in pre-launch initiatives (TVL pre-deposit, testnet interactions, etc.)

A user's transaction capabilities are directly determined by karma, which discourages Sybil attacks and rewards constructive network contributions.
