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.
0x is an open protocol that is designed to offer a decentralized exchange as part of the Ethereum blockchain. 0x is made using a protocol that involves Ethereum smart contacts that allow those around the world to run a decentralized exchange. The team behind 0x strongly believes that in the future, you will find thousands of tokens from Ethereum and that 0x can provide an efficient and trustworthy way to exchange them. 0x have several benefits such as it can be any asset. The 0x protocol facilitates the exchange of a growing number of Ethereum-based tokens including currencies, game items, and many more digital assets. Besides, it has a networked liquidity. By sharing a standard API, relayers can easily aggregate liquidity pools, creating network effects around liquidity that compound as more relayers come online. 0x also can be exchanged anywhere. 0x allows trade functionality to fade into the background, enabling developers to focus on building while 0x handles the exchange. The co-founders of 0x are Will Warren and Amir Bandeali, the first of which is the CEO and the second of which is the CTO. Both are in smart contract research and development. Warren used to conduct applied physics research at the Los Alamos National Laboratory after studying mechanical engineering at UC San Diego. Bandeali used to be a fixed income trader with DRW after he studied finance at the University of Illinois, Urbana-Champaign. 0x doesn’t charge fees of any type to use their protocol; it is free. However, if someone chooses to create a decentralized cryptocurrency exchange using the protocol, that person, known as a Relayer, can charge fees. How does it work? 0x protocol works where : A “Creator” sends his request and at that same point the request is posted in an off-chain arrange/order book by the “Relayer”, next to which the request is acknowledged by the “Taker” by pushing the exchange into the task’s DEX smart contract. Thus, the 0x protocol uses off-chain order books, which is maintained by a relayer for settlement of trade between two parties. Relayers, being behind the maintenance and creation of these channels are incentivised by charging and collecting fees. 0x (ZRX) Token: ZRX token is the unique aspect of 0x project which will be used to pay ‘relayers the trading fees by the users of the protocol. It is also a governance token in a decentralized form for the 0x protocol’s upgrade.
