Greetings Friends;

In this article, I’ll discuss Leviathan, the post-quantum solution the market needs to take a quantum leap as quickly as possible. After all, why wait if the solution is right here in our hands? So, if you live in the real world, you know that transparency has limits and that the more freedom you have to come and go, the greater the future disruption will be and the higher the probability that you are being watched, due to the complexity of people’s interactions and the current system, right? So is it correct to say that transparency is the solution to humanity’s problems? Is staying in the loop and knowing everything about others the ultimate solution? I don’t know about you, but for me, it’s a bit unsettling to realize that transparency has become a glass house across hundreds of ecosystems of varying levels and access across the entire planet, and it persists. Now, applying this analysis to the crypto world… Imagine you decide to switch from traditional finance to the world of decentralized finance; the famous DeFi. So far, so good, right? However, as time goes on, you discover that this technological advancement and leap forward is nothing more than a future trap where your actions in the DeFi ecosystem will remain public forever; meaning all your transactions, balances, and financial strategies will be public forever, where any person, institution, or government agency can see them... Is that what your dream and your adventure in the new world(crypto) boils down to?

However, your persistence is neutral and positive, and you ask me: What’s the problem? I’ll tell you there isn’t one; where the transparency of today’s DeFi can be useful for auditing, but terrible for financial privacy. If you receive a salary in crypto, pay a vendor, or simply want to save money, anyone with a blockchain explorer can track your transactions… the basics of randomness. But... but again, the problem gets serious: in the future, when quantum computers may be able to break the cryptography that protects most blockchains today, and since the beginning the core narrative has been about how having a private, fast, and secure bank against future threats; without giving up on DeFi innovation?

The answer to all questions and dilemmas is? Leviathan

What is Leviathan? A Layer 2(L2) Network? What does its Emergence Signify?

First of all, the term “Leviathan” is not associated with the extreme connotations of the mythological and demonic creature, where that meaning is reduced to a spiritual entity that dwells in the waters and represents spiritual blindness and destruction, embodying the insidious nature of evil. The idea of adopting this name for the Leviathan project is more succinct: although it has synonyms and dark associations, it carries with it the idea of opposing the divine order. In other words, this name represents opposition to the current system(DeFi), which needs to be dismantled as quickly as possible due to the coming new age of quantum computing.

Furthermore, Leviathan is the first post-quantum privacy Layer 2(L2) built on Neptune Privacy(NXT). In simple terms, it acts as a “shielding layer” on top of the XNT network.

In other words, the concept boils down to:

- Layer 2 (L2): It is a network that runs on top of XNT, inheriting its security, but processing transactions much faster and with greater privacy.


- Post-Quantum Privacy: This means that no future quantum computer will be able to break its encryption. Your financial data will remain secure for decades.

- Settlement on XNT: Leviathan bundles thousands of private transactions, proves they are correct using advanced mathematics(zk-STARKs), and records only a summary proof on XNT.

Therefore, when you use Leviathan, your transactions are completely invisible to the public. No one can see who sent the funds, who received them, the amount involved, or which smart contract was executed. Only you and the other party involved have access.

 

The Technology Behind It and the Paradigm Shift Brought About by the Miden Protocol...

To be clear, the XNT developers did not build Miden. So, they admire the project. In practice, Miden is a very well-supported and highly anticipated programmable layer 2, built on top of Ethereum, for now. The Miden developers intend to build their own private layer 1 to place Miden on top of it, with a stated three-year roadmap. Until then, they inherit all the transparency and risks of Ethereum. Neptune Privacy is a fully private, quantum-resistant, and scalable layer 1.

To explore the scalability aspect, the Neptune roadmap included building a fully programmable layer on top of Neptune Privacy, allowing it to explore a full range of DeFi features and applications(Dex, lending, etc.), while remaining completely private and quantum-resistant. With this, a layer 2, Leviathan, was built. Both layers are settled with $XNT. The thing is, Miden's technology served as inspiration for the creation of Leviathan, where the developers realized that the perfect L1 layer Miden wanted to build over the next 3 years already existed… Neptune Privacy. It's the ideal foundation layer for Miden. They just didn't know it.

So, essentially, the developers "took Miden's foundation" and placed it on top of Neptune Privacy. And that's what we call Leviathan.

Why Is It Revolutionary? Will Leviathan Implement Miden?

Until now, blockchain privacy solutions have had major limitations:

Tornado Cash – It only mixed ETH/ERC-20 tokens, was not programmable, and was targeted by governments.

Monero(XMR) – It is private, but not programmable and has limited scalability.

Aztec – Promised privacy on Ethereum, but faced technical challenges and changed course.

Leviathan, by implementing Miden as a Layer 2 solution, solves all three problems at once:

- Programmable privacy (you decide what to hide and what to reveal).

- True scalability(3,000+ TPS, 1-second blocks).

- Quantum resistance (your funds will be secure even when quantum computers exist).

Conclusion

To sum up, what should we keep in mind about this revolution? Simple: L2 Leviathan isn’t just another cryptocurrency project; it marks the first time a post-quantum, programmable privacy protocol is available as an XNT Layer 2 solution, and it’s already up and running(with a testnet coming soon).

Benefits?

1. Instant and Low-Cost Transactions:
Your transaction is confirmed almost immediately and at low fees, allowing you to bundle many transactions into a single proof, resulting in minimal transaction costs.

2. Total Privacy by Default:
No one sees your balance; no one tracks who you’ve sent payments to; and no one knows which smart contracts you’re using.
