Did Stephen Wolfram's Knowledge Engine Just Become a Quantum Neural Blockchain AI?

Quantum Computing is a new paradigm in computer science that leverages quantum phenomena like superposition, entanglement and interference to gain a significant speedup over classical algorithms when solving some complex problems. Here is a post to find out more about quantum computing. This opens incredible new opportunities in science and business, but also new threats.

A quantum algorithm created by Peter Shor in provides an exponential speedup to integer factorization and the discrete logarithm problem. The intractability of these problems is, precisely, the foundation of most of the public key cryptography the world uses today, like RSA and Elliptic Curve.

While breaking our current keys might take several thousand years using classical algorithms, it could be a task of just a few hours for a large quantum computer. Another quantum algorithm created by Lov Grover in provides a quadratic speedup to reverse a black-box function. This reduces the security of any generic hash function or symmetric key cryptosystem. So, quantum computers will have the ability to reduce or eliminate the security of our current cryptography.

Latest roadmaps expect to reach the 1 million qubit milestone by the end of this decade. Estimations are that RSA and Elliptic Curve cryptography will be broken somewhere between the 30s and mid 40s. The cryptography community is actively involved in addressing this risk by designing new cryptosystems that can be executed in classical computers but cannot be attacked by quantum computers.

This is called Post Quantum Cryptography. NIST, the US National Institute of Standards and Technology, is now in the process of creating a post quantum crypto standard which is expected to be ready between and We can expect to be changing our crypto algorithms to new post quantum alternatives in the second half of this decade.

Considering how cryptography is embedded in all our IT processes, this will not be a simple task. Before the time for migration arrives, we can get ready by analyzing how we use cryptography today. One of the most important features of Blockchain is immutability. Data, hashes and signatures in a blockchain are expected to be there forever.

And available to scrutiny by attackers. So, current blockchains will also need their own migration. This will likely take the form of a fork or a protocol update, creating a new post-quantum chain or addresses and a limited window of time for users to migrate their data and assets. Adapting blockchains to the postquantum era will require increased storage and computing resources. Probably the evolution of technology will account for that in most cases.

Perhaps IoT applications, where resource constraints are greatest, will have greater difficulty in adapting. There are several ongoing efforts to understand how blockchains might adapt to the postquantum era. To learn more, I suggest that you visit these resources:. What is quantum computing?

If quantum computers threaten blockchains, quantum blockchains could be the defense

Two researchers from Victoria University of Wellington in New Zealand have proposed a new quantum blockchain technology that, by exploiting quantum entanglement across time, could greatly increase the security of future blockchain systems operating on quantum networks. Visser and Rajan are persuaded that their quantum blockchain concept could permit watertight tamper-proofing of all records and transactions. Entangled non-local correlation seems instantaneous, or at least it propagates much faster than other physical interactions. In particular, entanglement between particles too remote to exchange signals limited by the speed of light has been repeatedly confirmed in research labs. It turns out that probing the state of one particle in an entangled pair affects the state of the other particle in subtle ways. For cryptography, entanglement is a double-edged sword.

A quantum blockchain can stop quantum computing from hacking it

There are often talks revolving around the quantum computing revolution and its advantages to the computing world. However, there is also a downside to quantum computers. Quantum computers pose a threat to cryptocurrencies, and they could introduce changes that the cryptocurrency owners will not like. Quantum computers, with their unique property of quantum entanglement of particles, are very secure modes of information and it would be impossible to break it. It uses something called as a quantum key distribution QKD that helps them to keep the security intact. Cryptocurrency work involves a private key that is used to access Blockchain and Bitcoin contained on it. Each transaction has its own cryptographic hash.

Quantum Entanglement: What it is & Why it is important

The coherence of a qubit, roughly speaking, is its ability to maintain superposition over time. The DiVincenzo criteria are a list of conditions that are necessary to construct a quantum computer, and they were first proposed by the theoretical physicist David P. The two additional conditions are necessary to implement quantum communication, such as that used in the quantum key distribution. Quantum entanglement is a special connection between two qubits. There are many ways of generating entanglement.

Previous Story

We outline a quantum-enabled blockchain architecture based on a consortium of quantum servers. The network is hybridised, utilising digital systems for sharing and processing classical information combined with a fibre-optic infrastructure and quantum devices for transmitting and processing quantum information. We deliver an energy efficient interactive mining protocol enacted between clients and servers which uses quantum information encoded in light and removes the need for trust in network infrastructure. Instead, clients on the network need only trust the transparent network code, and that their devices adhere to the rules of quantum physics. To demonstrate the energy efficiency of the mining protocol, we elaborate upon the results of two previous experiments one performed over 1km of optical fibre as applied to this work. Finally, we address some key vulnerabilities, explore open questions, and observe forward-compatibility with the quantum internet and quantum computing technologies.

Stranger Than Fiction: How Entanglement Could Save Blockchain From the Threat of Quantum Computing

The biggest danger to Blockchain networks from quantum computing is its ability to break traditional encryption 3. Google sent shockwaves around the internet when it was claimed, had built a quantum computer able to solve formerly impossible mathematical calculations—with some fearing crypto industry could be at risk 7. Quantum computing is the area of study focused on developing computer technology based on the principles of quantum theory. The quantum computer, following the laws of quantum physics, would gain enormous processing power through the ability to be in multiple states, and to perform tasks using all possible permutations simultaneously 5. Classical computin g relies, at its ultimate level, on principles expressed by Boolean algebra. Data must be processed in an exclusive binary state at any point in time or bits. While the time that each transistor or capacitor need be either in 0 or 1 before switching states is now measurable in billionths of a second, there is still a limit as to how quickly these devices can be made to switch state. As we progress to smaller and faster circuits, we begin to reach the physical limits of materials and the threshold for classical laws of physics to apply.

What Quantum Computers Mean for the Future of Blockchain

Fintech is becoming an increasingly important sector within financial services. Many of our clients are wary of cryptocurrencies but have a greater belief in the future of blockchain technology. However the potential arrival of quantum computing could be a total game changer yet is rarely discussed outside the sphere of scientific journals. For the time being this is clearly at prototype stage but the following interesting article from Cointelegraph examines the potential impact of quantum computing on the blockchain sector.

Will quantum computing impact the blockchain space?

The electricity transactions of microgrids face several problems: the high platform management cost, the low security, and the untimely consumption of scattered electricity. To solve these problems, this paper presents a multi-microgrid thermal game model based on quantum blockchain. Specifically, a dynamic model was established for the noncooperative game between aggregators, microgrids, and large users to maximize the benefit of each party, and to realize the timely consumption of scattered electricity. Next, a transaction platform was constructed based on the two-round password based authenticated key exchange PAKE protocol, which eliminates non-interactive zero-knowledge NIZK , aiming to substantially enhance the post-quantum security of transactions. Then, the quantum signature using two-particle entangled Bell states was adopted to safeguard the quantum communication of electricity transactions, and authenticate the nodes.

The mathematical principle of blockchains can be used in improving AI research and security. Do you think that blockchain security will be as strong in the post-quantum computer era as it is nowadays? Discovering a block might be "hard" if you're not ready to throw a couple million dollars in mining operations when applicable - as many DLTs use pre minted tokens , but what happens when we introduce quantum computing to the mainstream public? In opposition to traditional blockchain platforms, the Tangle uses Directed Acyclic Graph as its backbone, or simply DAG which allows the network to possess abilities like infinite scalability an other aspect that no other DLT possesses at the moment , quantum-proof security, and literally 0 transaction fees, as the network is not relying on blockchain and "miners".
