The blockchain ecosystem is set to witness a transformative leap in privacy and enterprise adoption with the introduction of Midnight, a privacy-centric sidechain developed under the Cardano banner. Announced at ScotFest 2022 in Edinburgh, Scotland, this project represents a significant stride in Cardano’s ongoing commitment to innovation.

The Genesis of Midnight

Midnight’s journey began five years ago, with an official introduction on social media platform X (formerly Twitter) space on 10 October 2023 by Charles Hoskinson, CEO of Input Output Global (“IOG”) and Founder of Cardano, alongside Midnight CEO Eran Barak.

Midnight’s Core: A Privacy-Centric Blockchain

According to a blog post by TapTools published on 12 October 2023, Midnight distinguishes itself as a 4th generation blockchain, squarely focusing on addressing the inherent privacy issues in blockchain technology. It leverages the robust Zk-SNARK technology – a cryptographic tool enabling verification of possession of certain information without revealing the information itself. This protocol plays an instrumental role in protecting user identities and ensuring transaction confidentiality. Additionally, Midnight’s GDPR compliance and regulation-friendly nature are augmented by Kachina, a next-gen virtual machine that facilitates private smart contracts.

Enterprise Emphasis: Breaking Barriers in Blockchain Adoption

Enterprises have traditionally been wary of blockchain technology due to privacy concerns. Midnight addresses this barrier by providing a dual ledger system – both public and private – enabling enterprises to manage data disclosure levels. Eran Barak stresses the importance of data and metadata confidentiality, a crucial aspect for enterprise dApps deployment. Furthermore, Midnight’s focus on service availability and reliability reflects in its design philosophy, mirroring Input Output Global’s approach with Cardano, known for its exceptional uptime record.

Service Availability and Cost Predictability

Midnight goes beyond just privacy; it emphasizes service availability, ensuring users have uninterrupted access to their data – a vital feature for enterprises where downtime can incur significant costs. Moreover, it offers cost predictability and budget-friendly fee structures, with the added convenience of fiat settlements for enterprise transactions.

Bridging Traditional and Decentralized Finance

Midnight is poised to be a catalyst in the integration of traditional finance (TradFi) with the blockchain industry. By creating an accessible bridge between TradFi and decentralized finance (DeFi), Midnight aims to dismantle adoption hurdles, positioning both itself and Cardano as frontrunners in this integration process.

Innovative Technological Foundation

Rooted in the concepts outlined in Input Output’s “Minotaur” whitepaper, Midnight is developed as the first 4th generation blockchain. It incorporates multi-resource consensus, identity protection, ZK Snark technology, and private smart contracts. Hoskinson views Midnight as a technologically sophisticated product, combining proof of work and proof of stake in a novel amalgamation, symbolizing the innovative spirit of this project.


Charles Hoskinson articulates the significance of Midnight in the broader Cardano ecosystem, highlighting its potential to revolutionize industry applications and serve as a bridge between traditional and decentralized finance. Midnight, with its unique features and focus on privacy and enterprise adaptability, stands as a testament to Cardano’s visionary approach in the blockchain domain, poised to redefine how privacy and technology converge in the blockchain landscape.
