InterLink Seoul Private Mainnet – The Blockchain Foundation

InterLink officially launched its Seoul Private Mainnet (Version 6.0) in June 2026. This marks a major milestone after roughly a year of development. The mainnet is the blockchain foundation that powers all InterLink transactions, staking, and real-world asset tooling. This guide explains what the mainnet is and why it matters for users.

What Is the InterLink Mainnet?

The InterLink Mainnet is the live blockchain network designed to process transactions, smart contracts, staking activities, and other operations within the InterLink ecosystem. The Seoul Private Mainnet (Version 6.0) is the first version of this network. The mainnet is named 'Seoul' as a tribute to South Korea's postwar economic transformation, known as the 'Miracle on the Han River' a symbol for the project's own growth ambitions.

Before a blockchain becomes fully operational, projects typically develop and test their infrastructure in controlled environments. A mainnet represents the stage where the blockchain is running as a live network and can support real ecosystem activities. For InterLink, the mainnet provides the basic infrastructure needed for users and applications to interact with blockchain-based services. Instead of treating transactions, staking, and rewards as separate features, these activities can operate through the same underlying network.

Key features introduced with the Seoul Private Mainnet include:

• Fast transaction settlement with low latency
• Fixed transaction fees for more predictable network costs
• Native ITLG staking directly on the blockchain
• ITL reward distribution through staking activities
• RWA tooling for developing real-world asset applications

In simple terms, the InterLink free mining app is where users interact with the ecosystem, while the mainnet is the blockchain infrastructure supporting those activities.

What Does "Private Mainnet" Mean?

The term “private mainnet” can be confusing for people who are new to blockchain. Unlike a testnet, which is mainly used to test blockchain functions, a private mainnet is a live and functioning network with controlled access. This allows InterLink to operate its blockchain under real conditions while gradually expanding access and functionality.

The private mainnet allows InterLink to:

Test network performance under real economic conditions: InterLink can observe how transactions, staking, rewards, and other network activities perform when the blockchain is operating with real users and economic activity. Monitor stability and security: The controlled environment allows InterLink to identify technical issues, monitor network stability, and strengthen security before expanding access to a wider user base.

Introduce blockchain features gradually:

InterLink can activate new functions in stages, allowing each feature to be tested and adjusted on the live network before being made available more broadly. The ITLX DeFi Wallet is also available on the Seoul Private Mainnet, allowing users to access wallet and DeFi functions within the network. Therefore, “private” does not mean the mainnet is inactive; it means the network is already operating while access and participation remain controlled during this stage. The ITLX DeFi Wallet was connected to the Seoul Private Mainnet infrastructure on June 23, ahead of the official launch, with transactions already settling on InterLink's own chain infrastructure

What Changed With Version 6.0?

The June 2026 launch of Version 6.0 introduced several important changes to the InterLink ecosystem. The most significant difference is that key functions are now connected directly to the live blockchain infrastructure.

Native ITLG Staking

Version 6.0 activates native ITLG staking, allowing eligible users to stake ITLG directly on the InterLink blockchain. Unlike staking handled only at the application level, native staking is recorded and processed on-chain, making it an integrated function of the mainnet. This gives ITLG a direct role in network participation and staking activities.

ITL Rewards

Version 6.0 also enables ITL rewards through ITLG staking, connecting the two tokens within the mainnet's reward mechanism. The basic process is straightforward: stake ITLG → participate in the network → receive ITL rewards. This creates a direct utility for ITLG while giving ITL a role as the reward generated through the staking system.

Real-World Asset Tooling

Version 6.0 introduces the first stage of real-world asset (RWA) infrastructure, providing a foundation for bringing real-world assets and economic activities into blockchain-based applications. This can support future use cases involving tokenized assets, payments, and business-related applications, helping InterLink expand beyond basic digital asset transactions.

Live Private Network Operations

Version 6.0 marks the transition to a live private mainnet, where transactions, staking, rewards, and other blockchain activities can operate under real network conditions. The controlled environment allows InterLink to monitor network performance and gradually develop its infrastructure before broader expansion. It also provides the underlying blockchain foundation for future applications and services built on the InterLink Chain.

Why Does the Mainnet Matter for Users?

The mainnet matters because it gives InterLink users access to blockchain functions that depend on a live network. Its impact is different depending on how a user participates in the ecosystem.

For ITLG Holders

For ITLG holders, the main benefit of the mainnet is the availability of native staking. Eligible users can stake ITLG directly on the InterLink blockchain and receive ITL rewards through the on-chain staking mechanism. This gives ITLG a more practical role within the network by connecting it directly to staking, rewards, and ecosystem participation.

For ITL Holders

For ITL holders, the mainnet provides the infrastructure for using ITL across the InterLink ecosystem. ITL can support blockchain transactions, payments, Mini Apps, and other ecosystem services, allowing the token to function within a live network rather than only within the application environment. As more services are connected to the mainnet, ITL can support a broader range of on-chain activities.

For the InterLink Ecosystem

A functioning mainnet is important because future products need blockchain infrastructure to operate.

The InterLink mainnet is intended to support future applications such as:

• dApps and Mini Apps
• Payment services
• RWA applications
• The IBTE Marketplace
• Cross-chain infrastructure
• Other blockchain-based ecosystem services

Instead of each product operating independently, these applications can potentially use the same underlying network.

For trust and transparency

A live mainnet allows transactions and other blockchain activities to be recorded on-chain, creating a verifiable record of network activity. This provides greater transparency compared with an environment where users can only see activity or balances through a centralized application. For InterLink, moving to a live mainnet therefore represents an important step toward a more functional and transparent blockchain ecosystem. 

Conclusion

The InterLink Seoul Private Mainnet (Version 6.0), developed as part of the InterLink Labs ecosystem, is the foundation upon which the entire ecosystem is built. It enables native staking, ITL rewards, and real-world asset tokenization. For users, this means the project has moved from development to live operations.
