Nillion seeks to become one of the most powerful pro-privacy tools within the Arbitrum ecosystem and by extension, the Ethereum ecosystem.
The digital world has made our privacy a primary concern, and that is precisely what Nillion's recent integration with Arbitrum seeks to drive. This collaboration of technologies promises to revolutionize the way sensitive data is handled in the blockchain ecosystem. It not only seeks to improve privacy, but also optimize the way high-value data is processed and stored on the Ethereum network.
Boosting Arbitrum privacy
But above all, the integration of Nillion with Arbitrum responds to the growing need for solutions that are not only scalable, but also guarantee the security and privacy of information. Recall that Arbitrum, as a Layer 2 scaling solution, has demonstrated its ability to process transactions faster and cheaper than the Ethereum mainnet. However, despite these advantages, data privacy remains a critical challenge, especially in applications that handle sensitive information, such as decentralized finance (DeFi) and social media.
To address this situation, Nillion was born. Nillion seeks to address this need through an innovative multiparty computing protocol (Multi Party Computing – MPC) accompanied with a homomorphic cryptography system, and the combination of both allows something surprising: perform calculations on encrypted data without the need to decrypt it. This capability is essential to maintain the confidentiality of information while taking advantage of the benefits of decentralized applications.
How does Nillion work?
The way Nillion works is the union of solid cryptographic concepts and cutting-edge technologies. Firstly, because Nillion adopts an innovative approach based on Multi-Party Computing (MPC) to safeguard data privacy. This advanced protocol allows information to be fragmented into multiple parts, known as "shares", which are distributed among various nodes on the network. As a result, no single node has access to all of the information, ensuring that data remains confidential and protected from unauthorized access.
At the same time, Nillion makes use of information theoretical security (ITS) concepts, this with the purpose of adding a homomorphic cryptography capacity that falls into its main cryptography scheme: Linear Secret Sharing Scheme (LSSS), which adds a strong layer of security and privacy over all this development.
Nillion MPC Protocol Phases
Of course, all this is condensed in the way the Nillion protocol works, where we can highlight the following phases:
- Preprocessing to Create Shares: In this initial phase, the shares corresponding to each factor and term of the sum of products expression are generated and distributed. This process is based on standard MPC techniques and is crucial as it is performed independently of the input values. This means that the creation of shares is not influenced by the information to be processed, but depends solely on the number of entries involved. This approach ensures that shares are secure and that sensitive information is not exposed at this stage.
- Non-Interactive Calculation on Masked Factors: The second phase of the protocol focuses on performing calculations on the private data that has been masked. This stage is divided into three essential substages:
- Tickets: During this stage, the previously generated shares are distributed among the nodes and combined with user inputs to create the masked factors. This process is essential to ensure that each node only has access to part of the information, thus maintaining data privacy.
- Evaluation: In this phase, operations are performed directly on the masked data. Thanks to the properties of multi-party computing, nodes can perform complex calculations without needing to know the original data, which minimizes the risk of leaks of sensitive information.
- Departure from: Finally, in this stage the results of the calculations carried out are revealed. However, even at this point, the exposed information is guaranteed not to compromise the privacy of the original data, as only the necessary results and not the underlying data are presented.
This comprehensive and meticulous approach by Nillion not only protects data confidentiality, but also enables efficient and secure collaborative calculations, which is especially valuable in applications where privacy is critical, such as in finance, healthcare and in the management of personal data.

Greater privacy in Arbitrum
Of course, Nillion's integration with Arbitrum offers a number of significant privacy advantages for users. First of all, it allows secure data storage, meaning that users will be able to store sensitive information securely on the Nillion network. This helps prevent data from being exposed to possible attacks or leaks, providing greater peace of mind to users.
Another important advantage is found in the use of computing without decryption. Thanks to Nillion's blind computing technology, it is possible to perform calculations on encrypted data without the need to decrypt it. This approach eliminates the risk of sensitive information being exposed during the calculation process, which is critical to maintaining data privacy.
La secure collaboration is also a highlight of this integration. It allows multiple parties to collaborate on calculations on combined data sets without revealing the underlying information. This feature is especially useful in applications where privacy is essential, such as credit evaluation or data analysis, as it makes it easier to work together without compromising the confidentiality of the information.
Expandable to the entire ecosystem
Additionally, users will benefit from access to an expanded ecosystem. With over 600 dApps in the Arbitrum ecosystem, Nillion's integration will allow these applications to take advantage of blind computing capabilities. This will open new possibilities for the development of privacy-focused applications, thus expanding opportunities for developers and users.
Beyond privacy capabilities, Nillion offers other advantages that can benefit both users and developers. One of them is the Scalability. Nillion's architecture is designed to be highly scalable, allowing large volumes of data to be processed efficiently, adapting to the changing needs of users.
La interoperability is another key aspect. Nillion is compatible with other blockchain platforms, making it easier to integrate into different ecosystems and increasing its usefulness. This means that developers can use Nillion in combination with other technologies, expanding the possibilities for innovation.
Lastly, Nillion guarantees a robust security. It uses advanced encryption algorithms and a decentralized approach to ensure data protection, which is essential in an environment where cyber threats are increasingly common. This strong security allows users to trust that their information is protected.
The rebirth of digital privacy
Nillion's integration with Arbitrum represents a significant step forward in the search for solutions that offer both scalability and privacy in the Ethereum ecosystem. Combining Arbitrum's scaling capabilities with Nillion's privacy technologies opens up a range of possibilities for developing decentralized applications that can operate more securely and privately.
This collaboration will not only benefit current users of both platforms, but will also attract new participants to the blockchain space, driving the adoption of privacy-first technologies in an increasingly digitalized environment.
