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.
Bluzelle is a decentralized, scalable database service that aims to provide an effective data storage solution for the newly emerging blockchain ecosystem. It provides a solution to the scaling problems that developers of decentralized applications (dApps) face while using centralized infrastructure and traditional cloud-based databases. Bluzelle uses reliable ”swarm” technology, in which it stores tiny bits of data in groups of nodes or “swarms” which are distributed across the globe. Since this makes it independent of single data centres, Bluzelle’s scaling ability is limitless. Bluzelle adjusts the number of nodes and their location dynamically, reducing request time and improving overall performance. Bluzelle's swarm technology makes it extremely reliable as it redundantly stores pieces of data across the globe, eliminating a single point of failure. Since there are no data centres, Bluzelle’s resources are provided by network “producers”, who earn funds and pass on the savings to users. Bluzelle held an ICO from January to February 2018, selling 33% of its total supply of 500 million BLZ tokens and earning $19.5 million USD in the process. As of July 2018, Bluzelle has a circulating supply of about 183.02 million BLZ, with an individual price of $0.328 and consequently a market cap of around $60.25 million USD. The potential of an endlessly scalable storage service which is quick in its scaling, which is capable of storing any amount of data in a decentralized manner, is one that many investors may have an eye for. BLZ is still new and in its beginning stages, but its experienced team and excellent advisors work in its favour and are indicative of a bright future for the BLZ token. Investing in the token may not give high returns in a short period (since the cryptocurrency is so new and difficult to predict). So some more research is advised.
