(ValueWalk)   Johann Polecsak, co-founder and CTO of QANplatform was recently interviewed by ValueWalk about the blockchain and quantum computing.  Polecsak discusses quantum computing’s threats to the blockchain and how these can be prevented, and what the company is working on to offer a way out of the problem.
Polecsak explained the most worrying and already proven part is that quantum computers will be able to break most asymmetric cryptography-related schemes, including the digital signature scheme used by bitcoin, Ethereum, and other cryptocurrencies.
He said “QANplatform’s mission is to build a future-proof blockchain platform, not just another one on the list. Quantum-resistant security is our USP, but we put an enormous focus on lowering the entry barrier for the developer community, so startups and enterprises can build their Proofs of Concept (PoC) and Minimum Viable Products (MVP) as fast as possible to accelerate mass adoption.
The company raised a total of $2.8 million in funding over two rounds in June –in the VC round it raised $2.1 million with investments from Fairum Ventures, DeltaHub Capital, Insignius Capital, and BlackDragon.
Polecsak explained QANplatform has implemented a post-quantum signature scheme which is used to cross-sign transactions for when quantum computers become available. “We solve this issue by building integrations for existing and widely used and loved programming languages (Rust), DevOps technologies (Docker, Kubernetes), and Cloud platforms. Developers will build quantum-resistant smart contracts, DApps, DeFi solutions, tokens and cryptocurrencies, and NFTs on top of the QAN blockchain platform.
Polecsak discussed blockchain security networks in the next five years. “One thing is for sure, there will certainly be more focus on blockchain security as the criminals step up their game and try to get one step ahead of the networks.’
It is an incredibly complex matter to design and build decentralized systems like blockchains, let alone making them financially viable for a decentralized community where every single participant type is financially motivated to act according to the sustainability requirements of such a system.
