A veteran hacker warns how quantum computing can silently dismantle the encryption that protects bitcoin and blockchains. A hacker who has become a defender warns that most of the industry is sleeping with Crypto’s existential threat: quantum computing.

David Carvalho, CEO of the Post-Quantum Infrastructure Company, Nonis Protocol, began to invade 13 years old, experimenting with spam emails to attract job offers and gain attention from employers.

Eventually, this curiosity changed to the formal cyber safety work, where he used the same skills to defend systems instead of probing them. Today, it builds quantum resilient systems for decentralized networks and states that the cryptographic foundations of blockchains such as Bitcoin and Ethereum are dangerously outdated.

“The cryptography behind almost every chain is as weak as the rest of the world’s encryption,” Carvalho told Cointelegraph. “Quantum is coming for everything, as meteors came to the dinosaurs.”

Although Bitcoin and other blockchain developers often say there is still plenty of time to adapt, the window may be closing quickly. Efforts to implement quantum resistant signatures are underway, but Carvalho said it is far from being widespread or treated with the urgency that threats require.

Quantum threats by gathering bitcoin data today
For years, the idea that quantum computers could threaten Bitcoin seemed science fiction. But real -world developments suggest that the threat is changing from theory to initial practice.

Governments and giants of technology are already preparing for what is known as the “harvesting model now, decrypting later”. US federal agencies, such as the National Institute of Standard and Technology, have warned since 2022 on the urgency of adopting quantum resistant algorithms.

, while a White House memorandum led the NSA to advise government contractors to migrate to post -cantum encryption by 2035.

Today’s quantum technology is still short of Bitcoin’s hash sha-236 function or the digital signing algorithm of the elliptical curve (ECDSA) that protects encryption keys. But researchers like Carvalho argue that exponential advances – especially when combined with AI – can come abruptly. State-sponsored actors and cybercriminal groups are already collecting encrypted blockchain data now, hoping to decrypt them when quantum hardware recovers.

“The opponents who collect data from encrypted blockchain at the moment are not waiting to attack today,” said Carvalho. “They are building data sets for tomorrow. When technology reaches, they will unlock a decade of secrets in minutes.”
Despite these warnings, most of the Bitcoin community do not see quantum computing as an immediate threat, and there is no sense of widespread panic.

Current Bitcoin encryption is still considered robust against existing quantum machines, and developers have begun to explore defenses such as BIP-360, which propose quantum resistant addresses. Projects such as Nonoris de Carvalho Protocol are also working to help the transition from blockchains to post-quantum cryptographic patterns.

Quantum AI AI is the true apocalypse of Bitcoin
Although most conversations about quantum threats focus on brute strength attacks on cryptographic keys, Carvalho believes that the real danger is in the convergence of quantum computing and artificial intelligence. Together, he argues, they could allow stealthy and asymmetrical attacks that do not overload cryptographic systems with power, but dismantle them accurately.

“Everyone is waiting for a countdown that won’t come. You won’t receive a warning that a 10 -year -old bitcoin wallet has been cracked. You will only see the moved funds and no one can prove how or whom,” he said.

AI is already incorporated into cyber security – used for intrusions, intelligent contract audit and anomaly detection. But in the wrong hands, the same tools can be reversed. An AI attacker can automatically scan the open source wallets in search of bugs, simulate validator responses, and adapt real time to network behavior. If paired with a quantum computer capable of breaking private elliptical curve keys, the result would not be a high violation, but what Carvalho calls “silent collapse.”

“It’s not just about stealing coins,” he said. “It is about confidence to invisibly. Entire blockchains can be compromised, falsified governance systems and no one would know who did it or how.”

AI -oriented tests found vulnerabilities in cryptographic libraries that traditional tools ignore. Combine this with opponents that stock off encrypted data under the “now harvest now, decrypting” and the bases for a systemic violation may be in force.

Carvalho warned that this could mark Bitcoin’s true apocalypse if left without solution-a dramatic live crack from the Sha-236, but a slow and silent erosion of the trusted layers that keep the system united.

Bitcoin cannot defend against weak links
Despite all the conversation of Bitcoin decentralization, its real -world infrastructure remains deeply centralized. Cloud platforms, mining pools, and validator networks have vulnerable strangulation points that opponents with quantum capacity can explore. If a single cloud provider that hosts hundreds of complete nodes is compromised, the damage may shake throughout the network, regardless of how decentralized the protocol itself claims to be.

“Decentralization is great on paper, but if everyone is routing the same few spaces or trusting a handful of third party Apis, the game is already lost.”
The quantum threat can explore blind points in the systems around it: centralized infrastructure, aging technology and confidence premises.

Some projects are already being prepared. Oak Non-Noris, for example, are based on national security structures to build decentralized systems designed for a post-quantum world. Others are developing quantum -resistant rollups, new key formats, and protocol updates through Bitcoin (beeps) proposals or leveraging inherently secure technologies such as Starkware Starks.

The threat is approaching, but the answer is also growing. What remains is whether the cryptographic ecosystem will act before it is too late.

The UK’s electricity market has recently gone through some serious changes. There used to be a very straight option among a handful of big names, something more has turned into more complex – and is ready to excavate deep for more interesting businesses.

Most of the companies are still stuck with the same power supplier UK that they have used for years, are completely unaware that better deals are sitting there that are waiting to grab.

Old guard vs new wave

Everyone knows about traditional energy suppliers – British gas, EON, EDF – they are still large -scale players. But they are no longer the only game in the city. Dozens of new companies have made their way into the market, and some of them are offering deals that will make your accountants very happy.

What has changed here: These new business power suppliers do not have the same overhead cost as large corporations. There is no fancy headquarters in London, no army of middle managers, no mass advertising budget. They can pass those savings directly to their customers.

A manufacturing company in Leeds recently switched from one of a small expert supplier from Big Six and cut their electricity costs by 18%. A reduction of 18% to make only a phone call and fill some paperwork. This is the real money living in a business rather than disappearing in a large corporate machine.

Why size doesn’t always matter

The largest utility provider is not necessarily the best utility provider. Certainly, major companies have resources and nationwide coverage, but they also have bureaucracy, insult and a tendency to treat all customers in the same way.

Small energy suppliers often provide better customer service. When your power is out or your bill looks wrong, you talk to someone who can actually fix things in the call center instead of some poor person, who is reading from a computer screen. These suppliers get it – when your business cannot operate, you are losing money every minute.

There is a hotel chain that turned into a medium -sized power supplier UK after getting fed up with the customer service of its previous supplier. The new company assigned him a dedicated account manager who understands his business, knows the period of their extreme demand, and can adjust the contracts based on seasonal variations. Try to get that level service from the call center.

Technology revolution

Smart meters and digital platforms have completely changed how business power suppliers work. Real-time monitoring, automatic billing, and demand forecasting-technology, five years ago, is now standard.

But here is the interesting part: not all suppliers are using this technique equally well. Some have invested heavy in sophisticated systems that can adapt your energy use and identify cost-saved opportunities. Others are still originally on the spreadsheet and are expecting the best.

Smart utility provider companies are using data analytics to offer dynamic pricing that reflects real market conditions. Instead of paying the same rate 24/7, businesses can now use tariffs that vary depending on demand, day time and even weather conditions.

Regional advantage no one talks

Most businesses matter more than realization. An power supplier UK that focuses on specific areas, often has advantages that national companies cannot match. They understand the local infrastructure, having relationships with regional grid operators, and can respond rapidly when the problem occurs.

Scotland’s renewable energy surplus creates opportunities for Scottish businesses that do not exist anywhere else. The industrial heritage of northern England means that some suppliers are experts of high-manufacturing customers. Even the energy suppliers in London are especially focus on unique challenges of dense urban commercial districts.

Price vs. Service balance

The cheapest is not always the best, but the most expensive is not always better. Trick business is looking for power suppliers who provide competitive pricing for your specific situation and the correct balance of reliable service.

A restaurant group learned it hard when they switched to the cheapest supplier they could find. The rates were fantastic, but when they had billing issues, the customer service was no one. He finished switching again within six months, losing the money at the initial ending fee.

The best utility provider relationship is created at transparency, reliability and mutual understanding. The value matters, obviously, but knowing that your supplier will be when you need them.

What is coming next

The UK electricity market is still growing rapidly. Battery storage, electric vehicle charging, and renewable energy certificates, and new opportunities and challenges are continuously emerging.

Some energy suppliers have come to know how the wind is blowing and they are getting ready for it. While others are still trapped in the past, these companies are throwing money in solar projects, electric car charging points and all types of green tech, which need businesses over the next few years.

Bottom line

The UK’s electricity market offers more options than ever, but the option does not mean anything if you do not exercise it. Most businesses are paying more than the requirement because they have not disturbed to detect their options.

The power supplier in the UK has changed dramatically, and in the last few years, companies reviewing their arrangements have almost certainly missing from better deals. Whether it is low prices, better service, or more flexible terms, opportunities are waiting for businesses ready to look beyond clear options.

The question is not whether better deals exist; They do. The question is whether you are going to find them before your rivals.
