A few weeks ago, Vitalik Buterin was speaking at Devconnect 2025 in Buenos Aires in Argentina. Vitalik shared a very important statement during the event. He warned that elliptic curve cryptography “could break before the next U.S. presidential election in 2028.”
A few days later he posted another warning on X to ensure his message wasn’t ignored:
It’s not the first time the topic of quantum computing has come up. Interestingly, here at DisruptionBanking, we first mentioned quantum computing in a story about Ethereum in 2019. Back then Vitalik was preparing for World War 3, but perhaps he thought he had more time to prepare for quantum computing.
Are Blockchains Ready for Post Quantum Cryptography (PQC)?
As Ethereum relies on elliptic curve cryptography, it is vulnerable to quantum attacks. In October 2024 Vitalik wrote about how “real” quantum computers are not far away. Today he sees them as even closer.
Ethereum isn’t the only blockchain that will be affected by post quantum cryptography. In February Cardano’s Charles Hoskinson held a livestream broadcast titled “Post-Quantum Cardano.” He has also been quoted in multiple press outlets discussing the topic.
Other blockchains are looking at PQC too. In 2022 another leading blockchain, Algorand, introduced State Proofs, a post-quantum secure compact certificate that attests to and compresses the ledger’s state changes happening every 256 rounds. Algorand State Proofs are signed using FALCON, a post-quantum secure digital signature scheme. Incorporating FALCON into the Algorand framework has laid the groundwork for enhancing the resilience of Algorand’s ecosystem against potential quantum threats.
While the leading blockchains are still preparing for post-quantum cryptography, a startup called Krown Network has done more.
Introducing Krown Network
We live in a world where quantum computers are no longer sci-fi but a ticking clock. They are poised to shatter the elliptic curve cryptography that safeguards trillions in digital assets. Krown Network isn’t waiting for the breach. Meet Qastle, their groundbreaking hot wallet, launched on November 1, 2025, as the world’s first mainstream-ready shield against tomorrow’s threats today.
Krown Network is a Layer-1 blockchain ecosystem launching its mainnet on January 3, 2026, designed for high-speed, affordable transactions with native quantum-resistant security to protect against emerging quantum computing threats. James Stephens is the Founder and CEO of Krown Network and Krown Technologies.
James has CBE and CCFI qualifications, and sits on the Forbes Technology Council. Upcoming appearances include a live AMA on 256 MKT as well as the Texas Capital Live show with Lee Bratcher.
The $KROWN token serves as its core utility asset, powering staking, governance, and DeFi features like swaps and rewards within the network’s DEX and earn modules, with a total supply of 100 billion tokens and presale funds already fueling development.
At the heart of it all is Qastle, the world’s first quantum-secured hot wallet (launched November 1, 2025), which combines PQC and Quantum eMotion’s QRNG for unbreakable key generation, enabling seamless multi-chain storage and trading while future-proofing users against “Q-Day” decryption risks.
Qastle is available to download to your smartphone today, with an optional annual premium subscription for enhanced state-of-the-art security. In time, retail investors won’t be the only ones using the wallet. Institutional adoption of the wallet is next on the ambitious startup’s roadmap.
Focus on the Krown Ecosystem
A few weeks ago, Krown raised $1,835,685 during a pre-sale of $KROWN tokens. Amazingly the firm raised $500,000 in just 4 hours on November 6. The next big milestone is the Krown Network Launch Party that takes place in Nashville on January 3, 2026.
The January party is to reward early investors in the token. It is also the day of Krown’s MainNET launch. Together with the blockchain going live, this is the day of the official release of the native $KROWN Coin.
Krown also runs a YouTube channel where James and others frequently share insights with the community. The channel contains recordings of the live, public KrownMEETs where AMAs are hosted monghtly by the Krown C-Suite to help maximize transparency
In a recent KrownMEET event Craig Irvine, CFO of Krown Network shared information about the company’s financials.
Craig shared with the community on November 20 how Krown is very strong financially and how he thinks that the company is about to get stronger. He explained more about the Series A capital raise of $8 million that Krown is in process with currently.
Craig shared on the video that people want to invest because Krown is building the first quantum secure blockchain and ecosystem. He added how the Qastle wallet launch in November and the mainnet launch in January could lead the company to grow exponentially in 2027 and 2028. The target for the company is to be profitable by the end of 2027.
Krown Network Visibility
In October Krown was at ISC2 in Nashville where the imminent launch of the Qastle Wallet was unveiled. ISC2 Security Congress is a place where cybersecurity professionals can meet to discuss software security and AI, emerging threats and risk management.
In late October a Jumbotron billboard promoting Qastle in Times Square opposite the NASDAQ Screen went live.
To help raise further awareness of the Krown Network and Qastle, there is a growing ecosystem that you can access in Telegram. A lot of the members of the Telegram group are hodling the $Krown coin. But many of them are also interested in Quantum eMotion Corp (TSXV:QNC.V | OTCQB:QNCCF | FRA:34Q0), which Bloomberg describes as a communication solutions company engaged in developing and marketing cryptographic solutions based on Quantum Random Number Generator technology.
Quantum eMotion (QeM) has been a constant partner to Krown. The firm is listed on the Toronto-based TSX Venture Exchange. Some of the members of the Krown ecosystem have joined because they also invest in QeM stock. Others have joined after seeing stories about Krown on Marketwatch or Yahoo Finance. The Telegram channel includes members from all over the world, Canada, the U.S., Germany, Australia and many more. They are exceptionally welcoming.
What About Security Accreditation?
Quantum Computing is a very advanced technology. One of the leaders in the space is IBM that has several quantum computers in New York and Germany. The IBM Qiskit platform is something we have written about before at DisruptionBanking. More importantly, the tie-up between QeM and Krown involves a collaboration with the Platform for Digital and Quantum Innovation (PINQ2). This project is conducted in partnership with IBM Quantum’s Qiskit platform and aims to enhance Quantum eMotion’s QRNG2 technology and assess its resistance to simulated quantum computer attacks.
Krown has since published the results which confirms Quantum-Grade Protection in the Qastle Wallet.
Krown’s Plans for 2026
We spoke to Peter Biggs, CMO at Krown, about the company’s plans for 2026. Outside of a billboard in Times Square, Krown was also visible in the Football Championship in the United Kingdom, where it sponsors Southampton FC. The first match as sponsors took place on November 25. It was an electrifying contest with Leicester City which ended 3-0 to Southampton. Krown’s sponsored players this season are ex-Chelsea and Barcelona midfielder Oriol Romeu, and on the women’s team they sponsor striker Ellie Brazil.
There have been numerous mentions of Krown Network in various publications too. The firm has also begun a multi-year, six-figure deal with Cointelegraph and the last Krown Round Table livestream was broadcast from the ISC2 conference in Nashville.
Into 2026 raising visibility will continue to be a priority for Peter and the team at Krown.
For now, the priorities are on growing retail adoption, Peter explained. Institutional adoption is on the roadmap for the future. In the meantime, one of the challenges for Krown is getting its token listed on the major cryptocurrency exchanges. Another step would be exploring sponsorship of the Bitcoin 2026 conference, probably the most important crypto event in the world.
Krown Network Joins the Texas Blockchain Council
In the meantime, Krown Network has joined the Texas Blockchain Council. James spoke on the recent KrownMEET about his respect for the innovation that is happening in Texas. Not only is there a new Texas Stock Exchange going live in early 2026, but Coinbase just moved to the Lone Star State. He explained how many data centers are in Texas and more are moving to Texas, and many of them will need help understanding the threat of quantum computing.
If you haven’t done it already, place a bookmark next to Krown Network. We interview a lot of founders of promising startups at DisruptionBanking, and it’s rare to hear a story that offers the type of solutions that Krown does. It’s not a matter of whether you need Krown or the Qastle wallet, it’s a matter of how long you can delay getting involved.
