For more than a decade, blockchain developers and enthusiasts have promoted state integrity as their core unique selling proposition, emphasizing that transactions on public blockchains are accessible and visible to everyone. Public blockchains and the pseudonymity of their participants have largely prevailed and now represent the industry standard. However, this model also comes with drawbacks. Once an address has been linked to an institution or individual, all transactions become visible and attributable to the respective entity. 

How can an organization that wants to use a public blockchain for its operations do so without compromising the privacy of sensitive transactions such as payroll payments? Public blockchains such as Ethereum or Solana are not well suited for this purpose, as the risk of linking an address to an organization is simply too high. In recent years, several projects have set out to close precisely this gap in the market by searching for the optimal balance between transparency and privacy. Midnight is one of these projects. 

Midnight describes itself as a fourth generation blockchain that seeks to combine data protection and transparency. Its objective is to provide organizations with a platform for developing regulation friendly decentralized applications. 

The Challenge: Reducing Transparency 

Many of the major traditional blockchains are built on the principle of transparency. Every transaction is publicly visible and permanently stored. Yet this very transparency creates challenges for participants who do not wish, or are not permitted, to make all transactions publicly accessible. Suppliers, pricing, transactions, and trading partners would be publicly visible. Personal data would be exposed, and transactions such as payroll payments could be traced. Purchasing and payment behavior would also be fully transparent. Regulatory requirements such as data protection laws would be difficult to comply with, potentially leading to a loss of trust among customers. 

These limitations have so far prevented blockchain technology from being widely adopted in areas such as healthcare. Projects like Midnight were developed to address precisely these issues and offer viable solutions. Midnight enables programmable privacy with selective disclosure, laying the foundation for new application designs and business models. 

Midnight 

Midnight approaches this challenge by distinguishing between a “public state” and a “private state”. 

The public state contains the information necessary for the functionality and integrity of the network. This includes transaction proofs, cryptographic proofs, and executable smart contract code. Information that is intentionally made public is also part of this state. Everything required for consensus, traceability, and verification remains transparent and visible to all network participants. 

In parallel, a private state exists, anchored locally with​in ​a Trusted Executive Environment (TEE), a secure, isolated chip found in all modern machines and devices that allows applications to verify sensitive data without having to view it. In Midnight’s case, this ensures that sensitive user data is never ​sent to the network​. This includes personal information, identity data, business critical content, and in principle all sensitive data that should not or must not be made public. This information does not leave its local context, yet it remains functionally usable. 

The link between these two states is established through zero knowledge cryptography. This technology makes it possible to prove statements about private data without disclosing the underlying information. A simple example is applying for a loan. Today, confirming creditworthiness typically requires sharing a full credit report, exposing personal details such as exact date of birth, home address, income, and unrelated financial history. With Midnight, a cryptographic proof is sufficient to confirm that an applicant meets the required credit criteria. All other sensitive personal information remains hidden from the lender. 

Midnight operates according to this principle. Zero knowledge technology enables use cases in which statements about underlying data can be verified without revealing the data itself. Midnight’s protection of data and metadata can, for example, facilitate the tokenization of onchain and offchain assets, including tokenized real world assets. Proof of ownership can be recorded onchain without disclosing the identity of the owner, details of the assets, or related activities. 

Midnight could also help create fraud-resistant systems for recording preferences or opinions, such as surveys or voting processes. Eligibility and participation status can be verified without disclosing personal information or capturing individual votes. 

Private Transactions with Clear Compliance Logic 

Unlike most existing blockchains, Midnight protects not only data but also (transaction) metadata through ​its​ dual component tokenomics model that enables the creation of shielded and unshielded assets that can be used to preserve transaction confidentiality when necessary. Business transactions can remain confidential without sacrificing verifiability. At the same time, stable and predictable transaction costs enable reliable planning. 

Another key advantage​ of this model​ lies in the architecture’s regulatory compatibility. With viewing keys, you can selectively disclose specific information when required. Selective disclosure allows regulatory requirements to be met and reporting obligations to authorities to be fulfilled, without compromising user privacy or the confidentiality of sensitive corporate data. 

Network security and decentralization are ensured through collaboration with Cardano stake pool operators. Shielded private data remains decentralized with each respective user and is not aggregated in centralized databases, significantly reducing the risk of hacks. At the same time, native integration with Cardano and planned support for additional blockchains provide high interoperability and flexibility for future use cases. 

The Dual Token Setup with NIGHT and DUST 

Midnight differentiates between two distinct tokens and assigns clearly defined roles within a dual token model. The two tokens, NIGHT and DUST, serve different functions within the ecosystem. 

The NIGHT token is the unshielded native and governance token of the Midnight network. The token is public and transparent. Its primary role is to secure the network and to contribute to the stability of the network as it is used as the reward for block producers on the Midnight blockchain. Additionally, holding NIGHT tokens continuously generates DUST, a shielded resource that’s sole use is powering transactions within the network.  

NIGHT has a maximum supply of 24 billion tokens and follows a disinflationary logic. NIGHT will operate natively on both the Midnight and Cardano blockchains. A bridge will enable tokens to move seamlessly between these two chains, maintaining a constant circulating supply across the entire ecosystem. The DUST-generating function is expected to be live as soon as the mainnet is launched, while the governance function is planned for the future. 

In contrast, DUST is a used for transaction fees and is specifically designed to protect transaction metadata to prevent linkages between individual transactions. The Midnight team frames DUST as the compliance-friendly resource model. DUST is non-transferable and decays if unused. 

Through the clear separation between the two, Midnight’s dual tokenomics model aims to provide a solution that is regulatory robust, as well as technically and economically sustainable. 

Conclusion: The Next Generation of Blockchain 

Midnight seeks to resolve a fundamental dilemma of blockchain technology in the modern era: how to leverage the benefits of decentralized systems without completely sacrificing privacy. It attempts to address this challenge by combining zero knowledge technology with a novel architectural design. 

With its dual state system, the Midnight team aims to enable privacy preserving and regulation friendly blockchain applications. Organizations could thus benefit from the efficiency and transparency of blockchain technology while simultaneously meeting data protection requirements. 

As a fourth generation blockchain, Midnight positions itself at the threshold of a new era, one in which blockchain technology no longer has to choose between transparency and privacy but can integrate both within a single platform.
