Ryodan Systems AG has officially announced the mainnet launch of Intmax, a groundbreaking

layer designed to redefine Layer 2 solutions. This new protocol introduces an entirely novel architecture and a radical stateless design that significantly minimizes on-chain data, enabling ultra-low-cost and privacy-preserving payments on Ethereum, even during periods of heavy network congestion.

The core innovation behind Intmax is its Plasma architecture, a concept first introduced in 2017. While Plasma was initially deemed infeasible, Intmax has successfully overcome its technical limitations, making it the first protocol to realize Plasma’s vision in a practical and scalable manner. Unlike most Layer 2 solutions that focus on scalability through compression and off-chain execution, Intmax adopts a fundamentally different approach. It requires only approximately 5 bytes of on-chain data per transaction while remaining fully secured by Ethereum.

Intmax introduces a novel incentive mechanism called INTMAX Privacy Mining, which rewards users for contributing to network privacy. This mechanism creates a synergy between anonymity and incentives, fostering a healthy, decentralized ecosystem that upholds universal accessibility and the fundamental right to privacy.

The ITX token, which powers Intmax, exists in two forms: as a fast, private, native asset used for real-world payments on Layer 2, and as a standard ERC-20 token compatible with DeFi platforms and exchanges on Layer 1. This dual nature allows ITX to provide privacy and performance without leaving the broader Ethereum ecosystem, making it a unique and powerful asset.

The innovative architecture of Intmax has garnered strong support from the Ethereum core community. Justin Drake, a prominent Ethereum researcher, noted that Intmax is even more efficient than ZKRollup, highlighting that the chain does not verify SNARKs until the very end when users withdraw. Vitalik Buterin, the co-founder of Ethereum, also acknowledged Intmax as a hybrid plasma/rollup construction that puts a very small amount of data per user on-chain, offering properties that are somewhere between plasma and rollups.

Intmax addresses the growing concerns around financial privacy in the rapidly expanding cryptocurrency payment market. By providing a platform for high-volume Ethereum payments, including remittances, payroll, and cross-border settlements, Intmax ensures that sensitive data such as transaction history or account balances never appear on-chain. This design enables a truly secure and private digital cash experience for everyday use.

Leona Hioki, Co-Founder of Intmax, expressed her delight in finally bringing the protocol to the world after a long technical struggle. She emphasized the relentless desire for both privacy and near O(1) scaling, which led to the creation of Intmax. Mai Fujimoto, the other Co-Founder, highlighted the importance of blockchain being freely usable by all, not just the wealthy, due to congestion and high gas fees. She hopes that Intmax will become the foundation that delivers choice and dignity to more people around the world.

Intmax is a stateless Layer 2 protocol for Ethereum, developed by Ryodan Systems AG. It aims to accelerate blockchain mass adoption through constant minimal gas fees, instant transaction finality, and user-centric privacy.
