Layer 2 solution provider Tanssi announced that it will deploy the last testnet “Helios” before the mainnet on May 25th. This testnet aims to verify the stability and high performance of its “Appchains” architecture through large-scale stress tests, laying the foundation for the official launch of the mainnet. Tanssi aims to build a dedicated chain for decentralized applications (DApps) with Ethereum-level security and scalability.
Core functions of the testnet: Dual improvements in compatibility and interoperability
The Helios testnet is built based on the Tanssi SDK independently developed by Tanssi and has four core functions:
EVM Full Compatibility: Supports seamless migration of Solidity smart contracts. Developers can directly deploy Ethereum Dapps to the Tanssi application chain without rewriting the code, reducing the difficulty of cross-chain development.
Dynamic Sharding Technology: By using an adaptive sharding algorithm to allocate data processing load, the theoretical throughput can reach up to 5000 TPS, which is nearly a thousand times higher than that of the Ethereum mainnet and can handle high-frequency trading scenarios.
Native Cross-chain Bridging: Integrate the Tanssi Bridge protocol to achieve cross-chain asset circulation with mainstream public chains such as Ethereum and Polygon. Users can directly use assets such as ETH and USDC for transactions within the application chain.
Modular Governance System: Open on-chain governance functions. Participants can participate in parameter voting by staking the native token TAN, such as Gas fee mechanisms and verification node access rules, etc.
Technical architecture: Layered design ensures performance and security
The application chain architecture of Tanssi adopts a “three-layer model” :
Underlying Consensus Layer: Based on Optimistic Rollup technology, it is consistent with the data of the Ethereum mainnet through the fraud proof mechanism and inherits the security of Ethereum.
Intermediate Service Layer: It provides precompiled contract libraries (such as orchards, payment gateways), developer toolkits (Tanssi CLI), and monitoring dashboards to simplify the dApp development process.
Upper Application Layer: Allows each dApp to independently customize chain parameters, such as block time and Gas token type, to form a dedicated application chain and avoid performance bottlenecks caused by resource competition.
The first batch of 50 ecosystem projects will participate in the Helios testnet, including the DeFi protocol Alpaca Finance and the NFT market Mintable, etc. During the testing period, the team will simulate a peak transaction load of 100,000 transactions per second, focusing on key indicators such as cross-shard communication latency and compatibility of smart contract execution.
Industry positioning: Focus on the niche market of the application chain
In the Layer 2 track, general-purpose rollups such as Optimism and Arbitrum occupy the main market. Tanssi focuses on the “application chain” sub-sector, targeting vertical scenarios that require customized infrastructure, such as:
High-frequency Trading dApp: Decentralized exchanges (DEXs) can achieve low-latency order matching through dedicated application chains.
Data-Sensitive Applications: The medical data sharing platform can customize privacy protection modules to ensure the compliant flow of data on the chain.
Enterprise-level Web3 services: Brands can build decentralized membership systems and enhance user stickiness by integrating the Token economic model.
The co-founder of Tanssi said, “The Ethereum ecosystem needs a ‘highway network’ rather than a ‘single route’.” The application chain model can not only meet the performance requirements of different scenarios, but also reduce costs by sharing the underlying security. It is the next stage form of the development of Layer.
Mainnet Planning and Market Outlook
According to the plan, the Tanssi mainnet will be officially launched in Q3 2025, initially supporting 50 parallel application chains. The native token TAN will serve as the basis for cross-chain bridge transaction fees and governance voting weights. In terms of token distribution, 20% is used for ecological incentives (testnet participants can receive early airdrops), 30% belongs to the team, and 50% is released through liquidity mining.
Industry analysts point out that Tanssi’s technical vision is innovative, but its success depends on the technical performance during the testnet period and the progress of ecosystem cooperation. If the Helios testnet operates stably, it may become another highly anticipated modular blockchain solution following the Avalanche subnet and the Cosmos SDK.
With the launch of the Helios testnet, Tanssi is attempting to open up a new track between “universal Layer 2” and “sovereign public chain”. Whether it can ultimately achieve the goal of “Ethereum-level infrastructure” will affect the future development direction of decentralized applications.
