A blockchain engineered for the post-quantum world

As the digital world accelerates, ensuring the long-term security of your assets and applications isn’t just important—it’s paramount. But a storm is gathering on the horizon: quantum computing. While this revolutionary technology promises incredible advancements, it also spells doom for today’s cryptographic standards underpinning most blockchains. Quantum computers, wielding tools like Shor’s Algorithm, will shatter these defenses, leaving digital assets and entire ecosystems vulnerable.

The fact is, many organizations have already taken this leap, while blockchain struggles to recognize it: Apple has secured iMessage, Cloudflare is securing HTTPS, and the US Federal Government has mandated all departments and contractors migrate to quantum-safe encryption.

Enter Zond: a pioneering Layer-1 blockchain, meticulously engineered from Ethereum’s proven foundation to proactively neutralize this future challenge. This isn’t a simple upgrade; it’s a paradigm shift toward enduring security in the face of unstoppable quantum progress.

While legacy blockchains grapple with the monumental task of migrating - facing complex technical hurdles, potential compromises in performance, and the daunting challenge of user consensus, Zond is built quantum-ready from day one.

This upgrade highlights the quantum ready smart contracts, opening the door for tokens from vulnerable chains, to find a secure haven, along with asset holders. Zond allows for the development of secure systems safeguarding user identities, votes, and digital assets (including NFTs) against tampering and exploitation. This paves the way for a new era of decentralized applications.

Backed by the QRL Foundation, Zond goes beyond quantum, emerging as a visionary platform designed not merely to withstand the quantum era, but to empower developers and users to thrive within it.

History, Current Status, and Roadmap

Background: The Quantum Resistant Ledger (QRL)

Launched in June 2018 and backed by the visionary QRL Foundation — the same organization powering the Zond upgrade — QRL was the first full-featured network engineered to withstand quantum-computer attacks. Rather than relying on traditional ECDSA, QRL implemented XMSS (eXtended Merkle Signature Scheme), a hash-based, forward-secure signature that’s been audited and proven resistant to quantum-computer attacks.

This long-term success is a testament to the QRL Foundation’s foresight in prioritizing post-quantum cryptography before it was widely recognized as necessary. By staying ahead of emerging threats, QRL has built a rock-solid reputation for security and innovation in a rapidly evolving landscape. Today, as blockchain networks around the world grapple with quantum vulnerabilities, QRL remains a trusted, future-proof platform.

Current Status

Since launch, the QRL Foundation has driven relentless research and development—efforts that began converging into a next-generation protocol by 2020 and culminated in a public devnet pre-release in 2022.

Releases:

1. December 2022 – public devnet pre-release: We kicked off a public development network, allowing community members and dApp builders to experiment with the Zond Virtual Machine (ZVM) and the Hyperion Solidity fork in a low-risk environment.
2. January 2024 – beta-testnet: Building on devnet, we launched our first beta-testnet.
3. Early 2025 – Testnet v1: Following a year of beta testing and incremental upgrades, Testnet v1 went live. This milestone marks our most stable testnet to date.

Roadmap

Zond represents a novel, never-before-attempted blockchain project that’s not seen elsewhere - well beyond a simple token on another blockchain. Technical challenges, audit findings or community-driven changes may require us to adjust things.

1. Further incremental upgrades: Each testnet phase in our roadmap progressively enhances our platform’s functionality and refinement, with each iteration serving as a milestone that brings us closer to a seamless and robust launch.
2. Comprehensive Security Audit & Review: Just like the QRL Foundation did with QRL, we’ll be engaging leading auditors to review Zond’s protocol and smart-contract toolchain.
3. Mainnet Launch (TBD): We have not yet set a mainnet date. The timing will depend on development, audit outcomes, and overall network stability.

Use Cases

Why quantum security matters

Decentralized Finance (DeFi) is revolutionizing the way financial services are provided, offering lending, borrowing, trading, and other financial instruments without traditional intermediaries. However, the security of these DeFi platforms relies on cryptographic algorithms that are vulnerable to quantum computer attacks.

Once large-scale quantum computers are available, they will break many of the encryption algorithms used to secure DeFi transactions, leading to unprecedented thefts and disruptions.

By leveraging Zond’s quantum-secure infrastructure, DeFi innovators can build applications that are not only secure today but will also remain secure in a post-quantum future, safeguarding investments and maintaining trust in DeFi ecosystems.

Use Case: Secure NFT Ecosystems

Non-Fungible Tokens (NFTs) represent unique digital assets, from art and collectibles to virtual real estate and more. The security of NFT ownership and transfer relies on blockchain technology and cryptographic techniques. However, powerful quantum computers threatens the security of these NFT ecosystems by allowing for the forgery of NFTs, theft, or unauthorized transfers. This vulnerability not only affects the financial aspect of NFTs but also the artistic and cultural value they represent, as the provenance and authenticity of digital artworks could be questioned.

Zond addresses this issue by allowing for the minting of NFTs using post-quantum secure cryptographic techniques, ensuring that the ownership and provenance of NFTs are protected against quantum attacks. This provides a secure foundation for NFT marketplaces and ensures that both buyers and sellers can trust the integrity of NFT transactions, preserving the value and authenticity of digital assets.

Use Case: Trustless Governance & Voting

Trustless governance and voting systems on blockchain aim to provide transparent, tamper-proof, and democratic decision-making processes for communities and organizations. These systems rely on cryptographic techniques to ensure the integrity of votes. However, quantum computers could compromise these systems by breaking encryption, allowing for vote manipulation or revealing voter identities.

The use of Zond’s blockchain and Zond Virtual Machine (ZVM) enables the development of voting systems that utilize post-quantum cryptography, ensuring a tamper-proof record of votes and safeguarding the integrity of governance and voting processes against quantum computer attacks.

Use Case: Decentralized Identity (DID) Solutions

Decentralized Identity solutions provide individuals with control over their personal data, enabling self-sovereign identity management. These solutions use blockchain and cryptographic tools to secure and manage identity credentials. However, the rise of quantum computing poses a significant threat to the security of these identities, as quantum computers could decrypt and access sensitive personal information, which could lead to identity theft, fraud, and other malicious activities, undermining the trust that individuals place in decentralized digital identity management systems.

The use of Zond’s blockchain and Zond Virtual Machine (ZVM) enables the development of solutions that are secure against quantum attacks, ensuring that personal data and identity credentials are protected. This allows individuals to manage their identities securely, with the assurance that their data is safeguarded with quantum-resistant algorithms against unauthorized access. Zond makes it easier for projects to offer individuals decentralized identity solutions that are quantum safe, providing a robust and secure foundation for self-sovereign identity management.
