What Is InterLink Testnet? Taj Mahal Testnet Guide For Beginners
Sep 07, 2026
Our journey
InterLink Labs has officially launched its first public testnet, named the Taj Mahal Testnet, in April 2026. This marks a major milestone in the project's journey toward building a human-centric Layer 1 blockchain. The testnet is the first phase of a multi-phase program designed to validate the network's performance, security, and scalability before the mainnet launch. This guide explains what the InterLink Testnet is, why it matters, how to join, and what you can do on it.
What is the InterLink Taj Mahal Testnet?
The Taj Mahal Testnet is the first major public testing phase for InterLink Chain, a human-centric Layer 1 blockchain. It went live in April 2026 and represents the beginning of InterLink's transition from development to real-world operation. The testnet is named in honor of the Indian community, recognized as one of the largest communities in the InterLink ecosystem. Each subsequent testnet phase will carry the name of an iconic landmark representing a community honored within the Human Network.
Key Concept: Testnet vs Mainnet
A testnet is a separate blockchain network used for testing purposes. It operates just like the main network but uses test tokens with no real value. Developers and users can experiment, build applications, and identify issues without risking real assets. The testnet phase is essential before launching a stable mainnet. The InterLink Chain will go through multiple testnet phases, each more refined than the last, with the Taj Mahal phase serving as Phase 1.
Why does the Testnet Matter?
The testnet is more than just a technical exercise. It serves several critical purposes for the InterLink ecosystem.
Real Blockchain Utility
Unlike many blockchain projects that launch testnets with no working applications, InterLink already has a live dApp running on its testnet. The first decentralized application, called BitFlip, is a fully on-chain Bitcoin price prediction game. This demonstrates that the InterLink blockchain infrastructure is capable of supporting real decentralized applications with actual economic activity. It also sends a clear signal to developers that the ecosystem is ready for building, encouraging them to explore and contribute to the growing network of Mini-Apps and dApps.
Stress testing the Network
BitFlip is primarily a stress test rather than a consumer product launch. By running a live prediction game with real staking activity, the team is gathering data on how the network handles concurrent transactions and whether finality holds up under genuine user demand. The game operates with 5-minute rounds and continuous user interactions, creating a steady stream of on-chain activity that pushes the network to its limits. This reveals performance bottlenecks, transaction processing capabilities, and potential vulnerabilities that can be addressed before the mainnet launch.
Performance Metrics
The testnet is already demonstrating impressive performance metrics:
- ~2,000 settled TPS in the first testnet phase
- Deterministic finality under 2.3 seconds
- Ultra-low fees and EVM-compatible
- Quantum-resistant cryptography and bot/Sybil defense
Building Trust and Transparency
By showing working applications running live on-chain during the testnet phase, InterLink is demonstrating real infrastructure rather than just theoretical promises. This builds confidence among developers, investors, and users. The testnet also serves as a transparent proof of progress. It shows that InterLink is not relying on white papers and promises alone but is actively delivering functional technology that the community can test and verify for themselves.
How to join the InterLink Testnet?
InterLink has made the testnet accessible to verified users through a straightforward process.
Requirements
- To participate in the testnet, you need:
- A verified InterLink ID with completed facial verification
- A wallet connected to an active loginId
The Testnet Faucet
Verified Human Nodes can claim 0.01 tITL (test ITL) from the faucet to test transactions, smart contracts, and dApps.
How to claim:
- Step 1: Open the faucet portal
- Step 2: Enter your wallet address
- Step 3: The system automatically checks your streak
- Step 4: Claim your test tokens instantly
What you can do on the Testnet?
- Test transactions with ultra-low fees and ~3-5 second finality
- Interact with dApps like BitFlip, the Bitcoin price prediction game
- Deploy smart contracts in an EVM-compatible environment
- Build and test Mini-Apps using the InterLink SDK
- Explore the Human Network with identity-native settlement
BitFlip: The First Testnet dApp
BitFlip is the first fully functional decentralized application to go live on the InterLink Taj Mahal Testnet.
How BitFlip Works
The game is entirely on-chain with:
- No centralized resolver
- No off-chain middleware
- No manual settlement
- No third-party control
Why BitFlip Matters
BitFlip demonstrates that the InterLink blockchain infrastructure can support real decentralized applications instead of just theoretical scaling promises. The system must:
- Record BTC prices accurately
- Process bets quickly
- Lock rounds properly
- Settle rewards automatically
- Avoid downtime or lag
According to InterLink Labs, the RPC infrastructure handled all these tasks continuously without failure during live operation.
What Comes After the Testnet?
The Taj Mahal Testnet is just the beginning. InterLink Chain will go through multiple testnet phases, each more refined than the last.
- Future Testnet Phases: Each subsequent testnet will carry the name of an iconic landmark representing a community honored within the Human Network, with each phase progressively raising the bar across security, scalability, legal compliance, and ecosystem readiness.
- The Path to Mainnet: After the testnet phases are complete, InterLink will transition to its private mainnet. The InterLink Seoul Private Mainnet (Version 6.0) was launched in June 2026, marking the next major milestone after the testnet phase.
- From Testnet to Mainnet: Success on the testnet has already paved the way for mainnet adoption. BitFlip, after proving its viability on the testnet, has officially entered the mainnet. The testnet proved the feasibility; the mainnet is where the real journey begins.
Conclusion
The InterLink Taj Mahal Testnet represents a significant step forward in the project's development. It is not just a technical milestone, it is proof that the InterLink ecosystem can support real applications with real users.
