Quantum Resistant Ledger is a cryptocurrency based on the Python programming language, aimed at combating future attacks by quantum computers. This cryptocurrency is the brainchild of Peter Waterland who realised that Bitcoin, Ethereum, and other such cryptocurrencies have no protection against future technology. It claims to be a “future-proof” cryptocurrency which enables transactions and decentralized communication while providing protection against classical as well as quantum computer attacks. The Quantum Resistant Ledger company was founded by Peter Waterland, who found that Bitcoin, as well as Ethereum signatures are susceptible to attacks by powerful quantum computers. His research on quantum computers and signature programs let to the development of this new cryptocurrency, designed to be resistant to the present classical attacks as well as any future quantum computer attacks. Their team is made up of a diverse range of members spread out across the world, including developers (core, blockchain, mobile developers, etc.), analysts, advisors, marketing managers, designers and more. Quantum Resistant Ledger is the first ever cryptocurrency and the only one in existence as of August 2018, to consider the threat that the future technology of quantum computing poses to cryptocurrencies and their working. It uses a technology specifically designed for post-quantum security, called XMSS, which makes it secure against powerful quantum computers even while using a Proof-of-Stake consensus mechanism. Security against cyber-attacks is a very serious concern in this digital age, especially when you have digital assets whose loss is likely to lead you to bankruptcy. QRL is the first blockchain technology that provides durability and stability through resistance to quantum computer attacks. The encryption methods used by modern blockchains can become vulnerable to quantum computers over the next ten years. QRL tries to create a blockchain with long-term stability. By using blockchain technology, the QRL platform creates a “ledger” that generates hashes in such a way that it is virtually impenetrable to any type of computer attack.
CommerceBlock is a public blockchain infrastructure company that is architecting a platform that allows anyone to build and use financial products and services historically reserved for commercial banking customers. The CommerceBlock network will be the first technology platform that provides a combination of trust minimal trade, decentralised contract execution, on-chain derivatives, and asset-backed token issuance to public blockchains. The advent of the Bitcoin protocol has enabled permission-less financial innovation. CommerceBlock’s product offerings provide a suite of tools that enables anyone to build and use services that construct contracts, manage trade flows, engage in multiparty dispute management, issue assets, and hedge currency risk. Developers and end users will be able to manage all stages of a business interaction and fulfil their contractual obligations by utilising the CommerceBlock platform. These services will be integrated into infrastructure we have already implemented. We have released the first open-source implementation of the pay-to-contract and homomorphic address protocol outlined by Timo Hanke and Ilja Gerhardt. The protocol has been designed in such a way that all business logic, customer funds, and trade details are managed on the client side meaning at no point does CommerceBlock have access to customer funds or private information.
