Companies must be aware of the fusion between quantum computing and cybersecurity

New technological innovations are transforming economies and enhancing our living standards through increased productivity and reduced cost of production. In lieu of this technological evolution, hackers and cyber scammers are innovating new and innovative methods to hack into the systems of individuals and companies and steal the large amounts of data that are being generated with the help of data analytics and AI tools. Hence, cybersecurity has become an integral part of all business strategies and is a means to protect data from intruders. Cybersecurity enables professionals to protect any information available on the devices to assess future risks. One of the key players in this cybersecurity is quantum computing. To replace classical computing and deliver long-standing results, researchers and scientists are exploring quantum computing as a robust tool to enhance the effectiveness of cybersecurity platforms.

Even though there are various ways in which the implications of quantum computing can harm cybersecurity, there are several other qualities of quantum computing that can deliver exponential advantages for certain classes of problems, for example, factoring very large numbers, with profound implications on cybersecurity.

One of the biggest worries that cybersecurity analysts are facing currently is the emergence of new devices that are based on quantum physics and are considered to be superior to standard computers. These devices have the reputation of enabling cyber attackers to break into secure cryptography methods. Classical digital ciphers rely on complex mathematical formulas to convert data into encrypted messages for storage and transmission. Consequently, attackers can break into these cryptography codes and steal confidential information.

Cybersecurity experts believe that eventually, quantum computing developers will pose threats to the national security of a country due to their ability to break into modern cryptography systems and reveal encrypted messages and stored data. Besides, hackers can adopt advanced technologies, such as machine learning skills to develop and distribute deadly forms of malware.

Frauds and cybercriminals can also take advantage of the powers of quantum computing to create various novel approaches to breach cybersecurity firewalls. Even though such activities can also be computationally tolling on classic computers, with the integration of quantum computing technology, hackers can take advantage of its advanced features and create sophisticated attacks on larger networks of devices and networks.

Quantum computing is not just about the doom of cybersecurity applications. The technology can also help create robust cybersecurity encryption methods. With the help of privacy-enhancing computing (PEC) techniques, professionals can keep the data encrypted while in use and can also provide in-transit and at-rest protections. Since data privacy is a hot topic for individuals and business leaders, PEC can be deployed to create stronger encryption models. Also, homomorphic encryption can be deployed that enables the third parties to process encrypted data and provide results without ever having the knowledge of either. This type of encryption can use lattices, or some multi-dimensional algebraic constructs that would be impossible for intruders to crack. Cybersecurity is a good potential solution for different types of cybersecurity and encryption issues. Security-concerned companies must definitely understand the importance of quantum flexibility.

Quantum computing is a fast-approaching technology in the cybersecurity domain. Companies need to immediately leap into action and analyze the different ways to deploy quantum to enhance security and block intruders from stealing confidential data. Currently, the industry is witnessing a substantial increase in investment in solving the core problems around scaling error correction and algorithms. Enterprises should start thinking strategically about the long-term risks and the benefits of quantum computing technology and engage in serious ways to deploy the best practices of cybersecurity.

Quantum Computing and Cybersecurity: A Fusion that Cannot be Ignored - Analytics Insight

The year-that-went was one of general precarity, as fragile attempts at economic recovery were steamrolled by fresh waves of COVID,

Meanwhile, the arts industries squared up to asphyxiating restrictions, while meeting friends to soothe the nerves was marred by anxiety and awkward distancing.

Science thrivingBut necessity is the mother of invention and, in the face of all the challenges, science has thrived.

In Denmark, the worlds first wind-energy island was proposed (and South Korea quickly followed suit), a new species of whale was identified, and a dodgy GPS signal led to the accidental discovery of the worlds most northerly island.

Biggest impactThe biggest revelations hit the headlines far beyond Denmarks borders.

Selected for their impact, innovation and socio-cultural significance, here are Denmarks top five most exciting scientific discoveries of 2021.

1 Innovative chip resolves quantum computing headacheIn October, two young physicists at the University of Copenhagen put us a step closer to building the first large, functional quantum computer. A little background: the brain of a supercomputer is made up of memory devices called qubits. While an ordinary bit can store data in a state of either 1 or 0, a qubit can reside in both states simultaneously known as quantum superposition. Until now, researchers have managed to build small circuits, in which only one qubit can be operated at once. So it was hailed as a global milestone when Professor Federico Fedele and Assistant Professor Anasua Chatterjee simultaneously operated and measured multiple spin qubits on the same quantum chip the entirety of which was no larger than a single bacterium.

2 Broad horizons for broad beansBroad beans are rich in protein, easy to grow and Jamie Oliver the standard marker of populist cuisine makes a dip out of them. But they also produce vicin poisonous to over 400 million people in the world who are predisposed to the hereditary disorder favism. For these people, primarily in Asia, Africa and the Mediterranean countries, vicin can trigger acute anemia and liver disorders. In July, researchers in Copenhagen and Aarhus isolated the gene responsible for forming vicin in broad beans, paving the way for a vicin-free bean that could become a major future protein-source or make a globally appealing appetiser.

3 Metal detector rookie finds 1kg trove of ancient goldIn an absurd stroke of beginners luck, a man called Ole Ginnerup Schytz found fame in September when he picked up a metal detector for the first time and discovered a stunning cache of 6th century gold jewellery near the town of Jelling in Denmark. Experts dubbed it one of the most valuable archaeological finds in Denmarks history on a par with the Golden Horns of Gallehus. The hoards enormous wealth points to a prolific European trade network and suggests Jelling was a major seat of power. The jewellery will go on display at Vejlemuseerne in southern Jutland on 3 February 2022, before being rehomed in the National Museum.

4 Hotrocks could spell the end for lithium batteriesIn May, construction began on GridScale a remarkable new energy plant on the island of Lolland that can store renewable energy in stone. The method involves super-heating and super-cooling crushed pea-sized basalt in insulated steel tanks. The stone can store heat for many days and supply energy for up to a week outperforming lithium batteries on both cost and efficiency. The 35 million kroner plant was quickly dubbed hotrocks by the international community and will continue to be a hot topic into 2022, when moves will be made to integrate it in the Danish national grid.

5 Malaria medicine found to combat COVID-19In December, researchers at Aarhus University discovered that the malaria medicine Atovaquone can prevent COVID-19 infection. The medicine has a protective effect both before and after infection across different viral variants meaning it could be used for both prevention and treatment of COVID-19. Its a big find: Atovaquone is inexpensive, widely available and has already been approved by the US Food and Drug Administration. Its yet to be tested on Omicron, however, and has only been studied using lab-grown human cells.

In review: Top five Danish scientific discoveries of the year - The Post - The Copenhagen Post - Danish news in english

Did you miss a session from GamesBeat's latest event? Head over to the GamesBeat & Facebook Gaming Summit & GamesBeat Summit: Into the Metaverse 2 On Demand page here.

Will blockchain technology be good for the planet? Ive been asking people about that and the first impression is that it will be incredibly wasteful using networks of computers to redundantly verify transactions for cryptocurrencies, nonfungible tokens (NFTs), and ultimately the metaverse. The second impression is that it could be a lot less wasteful shifting to cryptocurrency than relying on our current financial system. I talked about this with one of the experts in the field, and we delved into these myths on a more factual level.

Kiayias is chief scientist at Input Output, a blockchain engineering company. Its the driving force behind the Cardano blockchain, which is a third-generation cryptocurrency, which tries to improve on second-generation cryptocurrencies such as Ethereum and first-generation cryptocurrencies like Bitcoin.

A decentralized cryptocurrency keeps track of all transactions by all addresses on a peer-to-peer shared record. One of Cardanos innovations is the ability to support high-transaction capacities, fast transaction times, and low transaction fees, through a system of proof-of-stake. Cardano is not minable. The blockchain is a record of all transactions, but rather than validation by anyone who performs the proof-of-work, transactions are validated by consensus proof-of-stake. This is also far more environmentally friendly than mining other cryptocurrencies, as they are not using enormous amounts of electricity.

Input Output builds blockchain based products for governments, corporations and academic institutions and upskill people across the world, and it is focused on making blockchain technology that is environmentally friendly. Thats going to be necessary as we move toward the metaverse, the universe of virtual worlds that are all interconnected, like in novels such asSnow CrashandReady Player One. (Kyle Wiggers wrote a piece on the environmental impact of the metaverse).

Three top investment pros open up about what it takes to get your video game funded.

Input Output has contributed $500,000 to Stanford University to allow blockchains to process many transactions even with limited connectivity, providing support for the Tse Lab at the Department of Electrical Engineering of Stanford University. The aim is to enable even smartphones to handle blockchain transactions, while offline, to lessen the amount of electricity used in transactions.

Heres our edited transcript with Kiayias, who is

also chair in cybersecurity and privacy at the University of Edinburgh.

VentureBeat: I wanted to hear more about the work youve been doing. Could you start there? Id like to hear about the background, and the interest youve had in the energy usage of blockchain.

Aggelos Kiayias: Ive been working in cryptography since about the mid-90s. I was a mathematician originally. Cryptography was my passion when I was an undergraduate. It was a very different time, as you know. But were in an exciting time now, especially for those of us working in this area. A lot of these ideas we had on a blackboard, now the time has come to see them implemented, deployed, and used by people. Its a great time.

With respect to energy efficiency, that was one of the very early open questions in the space. Bitcoin was doing something amazing. It was capable of providing an IT service without having any centralized entity that provides it. Its a self-registered service. You could be part of the service provision by just registering yourself as a node. Thats pretty remarkable. It was unheard-of to deploy an IT service like that before. Its great to focus on Bitcoin from this angle, because it moves away the cryptocurrency, so to speak. Theres a lot to learn from Bitcoin just from studying how its possible to deploy a global scale IT service like that, automatically.

At the same time, the observation was, early onwere talking about very soon after Bitcoin was deployed. You had this huge energy expenditure, and it was only getting worse. Another thing that makes the situation even worse than just the energy expenditure is that the product is agnostic of the source of energy. It motivates you to find the cheapest possible energy, and the cheapest energy that you can find might not be an energy that we want to harness. It might be based on non-renewable carbon-based fuels and so forth.

Early on, then, there was an open question around how it was possible to create the service, create the system like that of Bitcoin, but without having the same energy expenditure. That was something that motivated me. It was more than seven years ago when I started working on this, this particular question. Soon we were looking at various flavors of proof of stake. The problem is, none of these protocols were designed in a way that you could be convinced that they would actually work. A lot of my effort was to apply this mathematical rigor that we apply in traditional cryptographic protocol design. Its not so traditional, because cryptography is a very young discipline, but lets say traditional with respect to what you would get in a system like Bitcoin, which is very new, the new kid on the block so to speak.

The question is, is it possible to apply that same mathematical rigor and extract a protocol that can give you the benefits of Bitcoin, this decentralized service provision, an automatic service that can appear out of the self-interest of the nodes that join the network? And it turned out that its possible to do it. We were very good at not only designing the Ouroboros protocol, but getting it deployed, and in general influencing a lot of deployment. The protocol I designed not only found itself as the backbone of Cardano, which Im sure youre familiar with, but also influenced the design of other systems. Polkadot used elements of Ouroboros to design their system, as well as in other efforts.

This is also characteristic of a lot of the work we do. This is work we make publicly available. We have a tradition of scientific peer review. We try to put it in the context of the scientific development of cybersecurity and computer science at large. We validate it not just with cryptocurrency experts, but we validate it in a scientific way with people who have experience in designing computer science protocols, and specifically cryptographic protocols. That gives you a bit of the story behind some of that work.

VentureBeat: What do you think about the energy usage of the different protocols that are out there? If you look at Bitcoin or Ethereum or what some of the Layer-2 solutions do, taking the energy consumption down quite dramatically, to the point where its maybe not as big a concern anymoreare there still some things to be concerned about?

Kiayias: I wouldnt say Im optimistic that Layer-2 is going to help much. The protocol itself, which is the backboneas long as Layer-2 fundamentally relies on Layer-1, and if that Layer-1 is a proof of work-based Layer-1, then the only thing that makes it work is energy expenditure. Energy expenditure is going to go up as long as engaging in this mining operation is profitable. If Layer-1 has high utility, then having high utility is alsoit could also be that it supports a very successful Layer-2 thats also part of its utility. Even if Layer-1 is just the mediator of all the various things that happen at Layer-2, its still going to be a critical part of the infrastructure. Its still going to be profitable to mine with it. Its still going to consume vast amounts of energy. The design of the protocol itself is such that it consumes this amount of energy.

Now, this is not to say that the protocol is flawed. Its designed exactly to do that. The question is whether its worth it. We do a lot of things on planet Earth that consume vast amounts of energy. Bitcoin is one of them. The question we have to constantly ask ourselves is whether this is the best use of the resources we have, the technology we have, at any given time. Technology, after all, is always about finding and optimizing designs, proving them, understanding the problem you want to solve, and finding the most cost-efficient way to do it. In many ways Bitcoin showed the way. However, the way it spends its resources, it doesnt seem, at the moment, to be the best possible use of what we spend versus what we get out of it. Thats not aligning.

VentureBeat: As far as something like Ethereum forking over to proof of stake, do you believe that solves a lot of the problem? Or do we still have problems around that?

Kiayias: It certainly removes the energy expenditure fact. Any proof of stake protocolthere are differences between protocols. There are plenty of differences between proof of stake protocols. But in terms of energy expenditure, proof of stake protocols are similar in the sense that they use relatively small levels of energy, on par with running traditional servers. The difference with proof of work is tremendous. Any proof of stake protocol certainly makes the energy expenditure problem essentially disappear, at least at the level were seeing right now with Bitcoin. Thats only one dimension, though. Energy expenditure is not the only issue that blockchain systems have.

VentureBeat: If they do that, do they trade off something like security?

Kiayias: At the abstract level, you can think of it as a different security assumption. Theyre both secure. But if you look at the theory of security, security is always achieved under certain assumptions. Or to put it differently, its very rare to have a system that has unconditional security, as we say. There do exist some very simple systems in the history of cryptography that are unconditionally secure, but theyre extremely limited in applicability. Typically what you have in security is security proofs or security arguments that are conditional upon certain assumptions or certain behaviors or certain things that youd consider plausible.

Proof of stake or proof of work, they come with different assumptions. Theyre both conditional, I should emphasize. But the set of conditions are different. This doesnt simply mean that one is less secure than the other. In both cases, the conditions that you can argueof course, Im not talking about Ethereum specifically now. Im speaking very broadly about abstract, ideal proof of stake design. Both of these systems can be argued convincingly to be secure under a plausible set of conditions that are different in both cases.

VentureBeat: Ive also heard a very different argument about how the global financial system as it is can be very wasteful. That physical banks use a lot of energy, paper-based systems use a lot of resources. The comparison between that system and a system based on cryptocurrency seems like there is a big difference there. I dont know what youd think of that.

Kiayias: Ive seen this argument as well, but I dont buy it. Bitcoin, just Bitcoin, cannot substitute for the world financial system. A bank is not just a ledger. They have a whole infrastructure that includes customer service, backup systems around what to do when things go wrong. Its endless. There are a lot of other items there. Its possible to make such a comparison, but the places Ive seen this comparison being madeits too simplistic, comparing a brick and mortar world that includes things like customer service with just a ledger. Thats not realistic. Bitcoin, the ledger, is by itself insufficient as a drop-in replacement for the whole banking system.

VentureBeat: I guess its more of a comparison between centralized financial services and decentralized finance.

Kiayias: Yes, thats true. A comparison like that could be made. But I havent seen it being made in a convincing way. And I should say, even if someone makes this comparison convincingly, why not use less energy? Even if Bitcoin is more competitive energy-wise, we should still ask the question, whats the absolute minimum of energy we need to get a service like that? Just because Bitcoin is better than System X, that doesnt meanthe question here is not just what system is better, but if you want to do the job that System X does, whats the absolute minimum amount of energy we need?

This is the way we ask questions in computer science. Computer scientists look at questions like this. The problem, lets say, is sorting an array. The question is, whats the minimum number of comparisons you need? Its not about finding one algorithm and proving it. Its finding the best possible algorithm that does it. Im keen on doing this. This is what motivates my research and the research we do at Input Output. Certainly I think this is the right question to ask.

VentureBeat: I wrote about Ubisofts effort to bring NFTs into their games recently. They said that they were using Tezos, and that it was a lot more energy efficient. A transaction in Tezos was using a millionth of the energy of a Bitcoin transaction, so you dont have the gas fees. It was more like the equivalent of a couple of Google searches. It sounded good, but it seemed like the problem is that not many people are going to use that protocol.

Kiayias: Tezos is a proof of stake system, so these numbers are not surprising. Bitcoin is immensely more energy-hungry compared to any proof of stake system out there right now. In terms of the infrastructure, from the point of view of the end user, these things shouldnt matter too much. The end user tries to play a game or tries to exchange some artifacts they have, some art. Where the user does it is something that many end users are not too concerned about themselves.

But what are concerned about here, as far as the basic infrastructure questionwhat is a sound infrastructure to base the security of these transactions upon? This is the question that motivates the work were doing. This is the right question to ask. Theres plenty of systems out there, but the real question to ask is, are they secure? Have they been analyzed? What are their credentials? Were still at the very beginning of assessing system security in the blockchain space.

VentureBeat: Do you worry that were already wed to Bitcoin and Ethereum to the point where we might not be able to change?

Kiayias: No, I dont think so, to be honest. Were still very early. Were exploring so many different ways of doing this. There are a lot of things that everyone in the space is learning. Were still way too early to say that somehow the first mover advantage is going to eliminate possibilities for other systems beyond Bitcoin and Ethereum to be successful. Theres certainly a lot of room for that.

You could even imagine a setting where theres a multitude of systems that are all interoperable, with trustless bridges connecting them and the ability for people to seamlessly transfer assets between systems, without actually caring about how it works. If you look at the internet itself, its a connection of quite diverse networking backbones, but we dont care now. The packets coming from my machine reach yours and vice versa. Everything is happening seamlessly in the background because the internet infrastructure has been optimized to work like this.

This is a viable future for the blockchain space. You have a lot of systems that interoperate. Eventually what you expect is that some of the systems will go away and some of the other systems will grow, depending on their ability to scale, have sound economics, and interoperate with existing systems and legacy infrastructure. Thats very important. You cant imagine this technology in complete isolation. It must interoperate with existing infrastructure and financial systems and so forth.

VentureBeat: Do you think, for things like NFTs and games, that theres an obvious solution yet, an ideal protocol?

Kiayias: I should say theres a lot of research to do even in the NFT space. The basic backbone of what is an NFT is well-understood, and there are systems that can give you that. I have to point out, however, that Ive also seen a lot of subpar implementation of the NFT concept. In other words, even though the expertise is there around how to provide the basic NFT, its a bit unfortunate that I also see a lot of insecure implementations of that concept in different platforms. However, at this point in time, there are systems, Cardano included, that can give you a sound implementation of the NFT concept. They can be readily used by those that want to use such systems.

VentureBeat: If blockchain overcomes the energy challenge, do you think thats the main challenge that it faces in adoption? Or do you think there are other challenges, other problems that have to be overcome?

Kiayias: No, there are more. There are definitely more. There are a few different ones that require expertise from different areas. Certainly energy efficiency is obviously one of them, but then we also have scalability. The work that we hinted at in the beginning of this conversation with Stanford has to do with scalability. Some of the research that the team at Stanford that were funding through this gift, its working around this next generation of scalability for Layer-1 operations. Layer-1 is an ever-expanding database. The question is, is it possible to have small, finite nodes to support that infrastructure without sacrificing the security of the system?

So far, blockchains like Bitcoin, Ethereum, and others, theyre quite monolithic in what they consider the concept of a full node. This is something that knows everything and checks everything. Obviously, by itself, this is not scalable in the future. Were talking about a neverending, ever-expanding database. We definitely need to solve that problem, and without a lot of work, a lot of research, both within Input Output and with partners like Stanfordtheres a lot of work weve done with others confronting the scalability problem.

Meanwhile, in all of these systems, you self-register because youre incentivized to do so. Theres a lot of research that still needs to be done to validate the soundness of the mechanisms that these systems use to incentivize the participants. For example, you can see in recent times all the debate that exists around pricing transactions. There are big issues in Bitcoin, and Ethereum as well, but Bitcoin has transactions which are extremely expensive. You can start asking the same principal questions. Whats the best way, if you want to auction this desirable space for transactions on the blockchainwhats the best way to price it so that you can still not break the incentives of the system participants?

These are just two examples where we do active research. There are lots of open questions to solve.

VentureBeat: Every now and then I also hear that quantum computing is going to be a threat to blockchain. It seems like it could also be used to defend blockchains. I dont know how serious a problem that is.

Kiayias: We take it seriously, very seriously. Its definitely not feasible at the moment with the quantum computing capabilities that exist right now. Its still an open question as to how well these techniques are going to scale. But its a very serious concern, and we have to understand how to develop protocols that, as we call it in security sometimes, are post-quantum secure. How can you develop a protocol that, after a quantum computer exists, still retains its security?

The good news, and perhaps something that people misunderstand sometimes, is that you do not need a quantum computer to be protected from a quantum adversary. Its possible to develop classical algorithms, classical cryptography techniques, that are secure even against quantum attackers. Thats something weve demonstrated in other areas of security, for example secure communications between websites, clients and servers. Its something that we understand how to do in a way thats post-quantum secure. Bringing this technology and understanding the right technology for the blockchain space is an ongoing research effort. Im quite active in this myself right now, together with my colleagues, but theres a general effort toward making blockchains post-quantum secure. Its something we take seriously, but its definitely within the realm of feasibility for the next few years, to have blockchains which are completely quantum safe, so to speak.

VentureBeat: Whats your own feeling about the potential for the decentralized internet, decentralized web, versus what we have right now thats centralized around big tech companies?

Kiayias: Im very enthusiastic about this. This is going to be one of the best applications of blockchain technology. Right now, what we observe is that all this centralization around the big corporations that basically silo a lot of informationin many ways it can be argued that it should be more of a public resource and less of something that one specific company should be able to capitalize on. There are a lot of issues of basic human rights. Do I have a right to see what information is collected about me? Do I have the right to transfer my information? Do I have the right to erase some of the information thats collected about me? These are basic questions that concern people in the IT law space, the legal aspects of information technology.

Blockchain systems do provide a lot of tools that can be used to make this situation better from the point of view of regulation. These ideas sometimes are called reg tech, regulatory technology. These are techniques that could be very useful in the future, and could upgrade the way we do regulatory compliance. Lets say regulatory compliance could catch up with the times. Im very optimistic about this. Some of the regulations we use right now are very antiquated. Were in a world where big corporations can just do regulatory arbitrage. They have a department in some jurisdiction where they operate because its advantageous for them to be there. Its a perversion of how the system should work on a global scale.

I do think that building these applications on top of a substrate of blockchain technology could somehow elevate the internet into something that has memory, something that has the ability for users to engage in a neutral space, without being locked into a particular company. This is a very promising direction for blockchain technology, and I think thats going to have a big impact on what we do in the next few years.

VentureBeat: Do you think theres some limited form of decentralization thats more ideal than complete decentralization? Do we need to form lots of DAOs in order to replace companies, things like that?

Kiayias: Its a great question. Whats the right level of decentralization for a particular type of application or system? Im very confident that theres going to be a wide spectrum. We cannot decentralize everything. Not everything makes sense to be decentralized. We still want to have services that operate as centralized entities in one way or another, just because there are needs for peak performance or agility.

Decentralized systems, no matter how you design them, are highly distributed. Their responsiveness will always be beaten by a super efficient, optimized centralized system. As the saying goes, the benevolent dictatorship is the best system that you could ever have, because theres only one dictator, he acts in everyones best interests, and he can act immediately and solve every problem without any delay. The only problem is that theres a scarcity of benevolent dictators.

Thats something we can solve with decentralization. Weve solved it historically with democracy. As we can see in the way human societies have evolved over thousands of years, theyve moved to settings where you have some centralization. You have a president or a prime minister. But you also have decentralized components of operation. You have elections. You have hierarchies of management. You have separation of duties, separation of parts of the government. This is not new. If you study political systems you can see a diverse landscape of some decentralized processes, some centralized, and a lot of checks and balances that glue everything together. I think exactly the same thing is going to happen in information technology.

VentureBeat: What are the areas of research that youre most excited about? What do you think is worth a lot of your time right now?

Kiayias: At this particular point in time, Ill mention scalability, which Im working on very actively with the team at Input Output. We have a lot of questions about how to optimize these functions. Making the system scalable, it also has to be agile, because different use cases on top of a blockchain require different types of operations. You want to create a system that somehow shapes itself according to a particular use case. Scaling for the occasion is always an important concern. Theres a lot of research going on about this right now.

I mentioned economics and game theory. Another topic Im working on actively right now with the team is governance. I cant emphasize this enough. Sound governance of a decentralized project on blockchain systems that are live is extremely important for their long-term success. One of the biggest problems weve seen in the space so far is systems getting into trouble because they cant properly manage the way that the system evolves. Its impossible, if we look at the history of software systems, to have the perfect system that stays there forever. What we know instead is that, first of all, bugs do happen. They have to be patched and corrected expediently. At the same time, circumstances do change. You have to be able to adapt. Governance and software updates in the decentralized setting is an extremely important question. Its something were very actively working on. So those are three examples of the top research streams we have going on right now.

VentureBeat: Are there any subjects where youre worried about the state of things, the direction that were going?

Kiayias: In the long term, nothing specifically. The whole space is maturing rapidly. We will be able to solve the main questions. Im very optimistic about the future, about the whole direction were going. I see a lot of bright people in the industry space. I see a lot of good expertise participating. I believe all of the major questions will be solved, from a technological point of view.

About the social aspects, one issue that worries me is that a lot of the research and a lot of the development were doing is driven collectively, the whole blockchain space by computer scientists and software engineers. We know from the history of recent information technology services like Facebook that you can do things, if you dont have an interdisciplinary approach of understanding the questions that youre trying to solveits possible to create systems that can do a lot of harm. Weve seen this, in the case of Facebook, with the spread of misinformation that has hurt public health in some cases during the pandemic, as well as in the case of Myanmar. There are a lot of cases where well-intentioned technology development has led to adverse effects.

What Im trying to do, and something were striving toward at Input Output, is to promote interdisciplinary work and research. Thats something I look forward to being more active with in 2022 and further on, so we develop solutions that really solve the important problems we want to solve, without creating new problems as happened with the hasty development of information technology services that weve seen in other cases, like Facebook as I mentioned.

VentureBeat: Do you have some confidence that, say, within five years well be able to solve the energy usage problem? Can we get to an ideal protocol?

Kiayias: First of all, I think energy usage is something that weve taken care of already. Cardano and other systems are going in this direction. We have a sound infrastructure that is not energy-hungry. But as for all the other questions, because there are many other questionsgovernance, as I mentioned, is a key question. Scalability in all use cases is a key question. The next five-year window is enough time to develop systems that are resilient and reasonably capable of evolving so that they are exceptionally long-lived. Im confident that the research and development weve done so far, and thats going to happen in the next five years, will take us to that point.
