In most current blockchains, a single token often serves multiple roles simultaneously, such as paying transaction fees, securing the network, and providing rewards for validators. However, this model also presents a significant issue: transaction fees often expose a lot of metadata such as wallet addresses, timestamps, and the relationships between transactions. This undermines privacy, especially for blockchains aimed at data security.
Midnight takes a different approach. Instead of using a single token, this network implements a two-token model that operates in parallel, consisting of NIGHT and DUST. Each token has its own role, thereby separating the network security mechanism from the transaction operation mechanism. This design helps balance the necessary transparency for the ecosystem and the ability to protect user data.
1. NIGHT: The core token that secures the network
NIGHT is the main token of the Midnight ecosystem and serves a role similar to the native token of many other blockchains. It is used for critical activities such as participating in consensus, network governance, and receiving block rewards.
The supply of NIGHT is designed to be fixed and tends to be deflationary, providing economic incentives for those participating in securing the network. Since this is a non-anonymous (unshielded token), transactions related to NIGHT can be tracked on the blockchain like regular tokens.
A notable point is that NIGHT will initially exist as a Cardano Native Asset. This allows Midnight to leverage the existing infrastructure and ecosystem of Cardano, while also enabling this token to easily access liquidity in the market. In addition to securing the network, NIGHT is also used for governance participation, allowing the community to decide the future development direction of the ecosystem.
2. DUST: The energy source for transaction operations
If NIGHT plays a role in securing the network, then DUST is the 'fuel' that operates the Midnight blockchain. DUST is used to process transactions and ensures that operations on the network run smoothly.
Unlike traditional gas tokens, DUST is a metadata-protected resource (shielded resource). This means that when users make transactions, the information related to metadata will be concealed, helping to limit chain analysis and traceability of identity.
This design helps Midnight maintain higher privacy compared to many other blockchains, where transaction fees often expose a lot of data that can be analyzed.
3. DUST is not a store of value asset
An important characteristic of DUST is that it is not designed to store value. Midnight describes DUST as energy in the physical world: it has utility value but will 'diminish' over time.
This means that DUST will gradually decline if not used, rather than accumulating like a typical token. This mechanism helps prevent speculation on transaction fee tokens while keeping network usage costs stable and predictable.
In addition, DUST cannot be transferred between wallets, which helps address legal concerns often associated with anonymous tokens. Since it does not function as a trading asset, the likelihood of being regarded by regulators as a financial token is lower.
4. The relationship between NIGHT and DUST
The two tokens in the Midnight ecosystem do not exist independently but are designed to complement each other.
A quantity of NIGHT will generate DUST over time, similar to a continuously replenished energy source. This ensures that the network always has enough 'fuel' to operate transactions while maintaining a balance between demand and supply of DUST.
This mechanism brings several important benefits. First, it completely separates the network security token from the token used for transaction fees. Second, it creates a stable and predictable fee level, reducing the risk of cost volatility when the network becomes congested.
Conclusion
The two-token model of Midnight is a relatively new approach in blockchain design. Instead of consolidating all functions into a single token, this system clearly separates NIGHT – the security and governance token, and DUST – the operational resource for transactions.
This design helps Midnight tackle two challenging issues of current blockchain technology: protecting user privacy and maintaining liquidity of the network token. If implemented effectively, the NIGHT and DUST model could become a notable design direction for privacy-focused blockchains in the future.
