Incentive Testnet: An Important Force in Promoting Protocol Success

In recent years, Proof of Stake (PoS) blockchains have become increasingly popular. Obvious signs of this trend include Ethereum's transition from Proof of Work to PoS, the thriving Cosmos ecosystem, and the rise of emerging PoS public chains such as Aptos and Sui.

The PoS mechanism relies on a network of validators, which presents two major challenges for projects: first, the value of internal testing is limited because the network's operation depends on external decentralized participants; second, the operating costs of nodes are high, requiring specialized skills and ongoing investment.

These factors contributed to the rise of the incentivized Testnet. Initially introduced by Cosmos through the Game of Stakes project, the incentivized Testnet provides a decentralized and low-risk testing mechanism for blockchain.

The Essence of the Incentive Testnet

The Incentive Testnet is a gamified project that attracts external validators, developers, and users to participate in blockchain network testing through rewards. This mechanism is primarily used to test the PoS infrastructure, helping projects build a strong network of node operators to ensure stability and decentralization at launch, while simulating a real environment to identify potential issues.

Participants can usually receive native tokens or stablecoins as rewards. Recently, the application scope of incentivizing the Testnet has expanded to testing in multiple areas such as smart contract deployment, governance voting, trading, and cross-chain infrastructure.

Key Considerations for Building an Incentive Testnet

Clearly define the goals

The project team first needs to identify the testing focus, considering scale, admission criteria, and success metrics. In addition to common node infrastructure testing, some projects also use Testnet to educate early users and validate specific features. For example, a certain DEX project successfully recruited over 11,000 traders, which not only tested the efficiency and liquidity of the exchange but also identified and fixed significant vulnerabilities.

Set Participation Threshold

Admission criteria ensure that participants meet minimum standards. Requirements for validators may include hardware configuration, experience and technical skills, and even geographical diversity. The scale of participation is also an important consideration to achieve sufficient decentralization. The thresholds vary for different types of projects, such as exchange functionality tests typically having lower barriers. KYC is a common requirement to ensure compliance and prevent attacks.

Design incentive mechanism

The core of the incentive Testnet lies in ensuring comprehensive testing and community experience accumulation through project design and reward distribution. Testing is usually conducted in phases, gradually covering various aspects of the network. Rewards are mostly in the form of native tokens, with some cases using stablecoins. Reward methods include two categories: task completion-based and performance-based, each with its own emphasis. Projects also need to consider the competitive or collaborative nature of the Testnet to achieve different testing objectives.

Promote the mainnet launch

The success of the Testnet is crucial for the launch of the mainnet. Through the Testnet, validators gain operational experience, developers become familiar with tools and documentation, and community contributors create supportive content. The project team should continuously interact with Testnet participants to maintain community vitality. Some projects further incentivize tool development and community participation by issuing grants and providing token authorizations.

In summary, the incentive Testnet plays an increasingly important role in driving the success of PoS blockchain projects as an innovative mechanism. Through careful design and effective execution, it not only helps projects test key functions but also fosters an active community ecosystem, laying a solid foundation for the smooth launch and long-term development of the mainnet.
