+## Project Overview :page_facing_up:
+
+Cyferio Hub is a confidential rollup router designed to bring scalability, privacy, and interoperability to Polkadot, its parachains, and external ecosystems such as Ethereum, Bitcoin, and Solana. The Cyferio SDK complements this by simplifying the creation and management of confidential (FHE-based) rollups, offering developers a toolkit to deploy privacy-preserving, scalable, and interoperable solutions.

+
+
+### Overview
+
+Cyferio Hub, built on top of Substrate, serves as a cache layer that links rollups to the Polkadot parachains. This integration simplifies cross-chain communication, enhances scalability, and allows developers to easily build and deploy applications. By providing a seamless settlement layer, Cyferio Hub extends the capabilities of existing rollups across various blockchain networks.

+
+Moreover, with the Cyferio SDK, developers can easily create confidential rollups that are compatible with existing Substrate-based applications. This compatibility ensures a smooth transition path for developers who are already familiar with Substrate's framework and ecosystem. Also, it brings privacy features to the table using FHE (Fully Homomorphic Encryption), such as confidential transactions, confidential governance, and confidential identity layer, engaging new users to the ecosystem.

+
+Last but not least, Cyferio Hub has been recognized for its innovative approach, winning <u>**the first prize in the "Building a Blockchain Based on Polkadot SDK" category**</u> and <u>**the Best Innovation Award**</u> at the [Polkadot Hackathon 2024 in Bangkok](https://x.com/OneBlock_/status/1857774803396210770). The team is confident in the project's potential to advance confidential applications across the blockchain ecosystem.
+
+### Project Details
+
+The Cyferio Hub project aims to unlock confidential applications with FHE rollups that are connected to the Polkadot and broader blockchain ecosystem. Our solution will be a fundamental infrastructure for all confidential applications with Cyferio SDK as FHE rollup framework and Cyferio Hub as a rollup router connecting these confidential rollups to the Polkadot parachains and other L1s. This will enable developers to build applications with comprehensive privacy-preserving use cases that are hard to achieve with general-purpose FHE rollups.
+
+Cyferio Hub is built on Substrate, leveraging its modular architecture to integrate with multiple rollups, parachains, and L1s. Cyferio SDK is a modular rollup framework with FHE integration that simplifies the creation and management of confidential rollups, providing developers with the necessary tools to build privacy-preserving applications. Our prior work includes a Proof of Concept (PoC) and a Minimum Viable Product (MVP) as documented in [Cyferio Hub](https://github.com/cyferio-labs/cyferio-hub-node), [Cyferio SDK](https://github.com/cyferio-labs/tmc), and [Website](https://cyferio.com).
+
+Additionally, we will further enhance the scalability and speed of transaction processing within Cyferio Hub by collaborating with DragonflyDB to develop an in-memory storage solution. This collaboration will ensure that our infrastructure can support the growing demands of privacy-preserving applications and cross-chain interoperability, providing a robust and efficient solution for developers.
+
+Furthermore, we are committed to fostering innovative privacy-preserving projects within the Polkadot ecosystem by incubating teams that are building novel confidential applications using Cyferio's tech stack. Our incubation program will provide these teams with the necessary resources, mentorship, and support to grow and scale their projects. By leveraging Cyferio Hub and Cyferio SDK, these teams will be able to develop cutting-edge privacy-preserving solutions that enhance the overall capabilities of the Polkadot network.

+
+
+### Ecosystem Fit
+
+Cyferio Hub unlocks a new dimension of applications with privacy-preserving use cases by integrating FHE rollups and cross-chain interoperability on the Polkadot ecosystem. Our target audience includes parachain developers and appchain developers seeking confidential rollup solutions and cross-chain data interoperability.
+
+For instance, with the upgrades of JAM (Join-Accumulate Machine), we envision that the FHE rollups created by Cyferio SDK can be deployed on JAM and leverage its advantages to enhance Developer Accessibility, Economic Flexibility with Agile Coretime, and improved Scalability.
+
+Moreover, we expect to integrate with Acala to leverage its mature DeFi platform and provide a new flavor of DeFi applications with on-chain confidentiality provided by FHE rollup. Privacy-preserving applications such as confidential stablecoin payment system, confidential lending protocol, and confidential DEXs can be built on top of it.
+
+Projects such as Fhenix offer FHE rollup solutions on Ethereum, but Cyferio Hub is the first project that brings FHE rollups to the Polkadot ecosystem and makes it furthermore compatible with the broader blockchain ecosystem. Therefore, with the cross-chain settlement and interoperability features provided by Cyferio Hub, we aim to expand the Polkadot ecosystem by bringing applications on other rollups to it.
