LBRY (pronounced “Library”) is a decentralized digital content distribution protocol and a marketplace for the same. It supports a variety of content which includes but not limited to videos, songs, ebooks, etc. LBRY uses blockchain at its core, which enables content to only be controlled by its author/ publisher, not by any third party, effectively eliminating issues like censorship and copyright strikes. Since the code of the LBRY project is open-source, developers can create their own decentralized apps (dApps). Content creators can use these apps to upload their content on the LBRY network and monetize it by setting a fee. LBRY credits or simply LBC is the cryptocurrency created by the LBRY network to fuel its entire digital content market. The LBC coin is required by consumers to access the monetized content on LBRY network. The LBRY platform also allows LBC mining by giving block rewards. Jeremy Kauffman co-founded LBRY Inc. with the vision of a decentralized global content hub, controlled and owned by no one. Currently, Jeremy is the chief executive officer of LBRY Inc. Before working on the LBRY project, Jeremy founded TopScore, a million dollars event and activity registrations startup. There are three other co-founders who serves on different positions in LRBY Inc: Alex Grintsvayg (Chief Technical Officer), Josh Finer (Director of Operations and Analytics), and Jack Robison (Protocol Developer). LBRY provides its own official app, which can be used to store LBC. The LBRY app is available for multiple operating systems such as Windows, MacOS, and Linux. Android and iOS versions are still in development. Other than its official LBRY wallet, users can opt for the Coinomi mobile wallet, which is recommended by LBRY. LBC can only be obtained through exchange. Users can also take advantage of LBC mining and various rewards given in LBC coin by LBRY network to its users. Although the concept behind the LBRY network has a lot of potential for growth, it faces competition directly against the entertainment giants such as YouTube and Netflix, and some of these platforms have been around for more than a decade.
Zcoin (XZC) is a cryptocurrency focused on privacy and decentralization. It is the first coin to implement the Zerocoin protocol that enables financial privacy through the power of zero knowledge proofs with a focus on making privacy easy to use. It is also set to be the first to release MTP an ASIC resistant, anti-botnet proof of work algorithm that remains lightweight to verify to ensure fair distribution of coins and decentralized security. Zcoin is an open source decentralized cryptocurrency that focuses on achieving privacy and anonymity for its users while transacting. To achieve this privacy and anonymity, Zcoin uses zero-knowledge proofs via Zerocoin protocol which is one of the most cited cryptography papers at this point in time. In other words, when you transact using Bitcoin or Ethereum or something similar, your transaction history is always linked to your coins by default which makes you vulnerable. That, because all it takes is one link to your personal information or IP to find out the origin of the coins.However, if you transact using Zcoin’s Zerocoin feature, none of your transaction histories is linked to the actual coins and only the receiver and sender know that you have actually exchanged funds. Zerocoin is a cryptocurrency proposed by Johns Hopkins University professor Matthew D. Green and graduate students Ian Miers and Christina Garman as an extension to the Bitcoin protocol that would add true cryptographic anonymity to Bitcoin transactions. Zerocoin was first implemented into a fully functional cryptocurrency released to the public by Poramin Insom, as Zcoin who is also the lead developer, in September 2016. At the initial stage, Zcoin uses the Lyra2z algorithm for proof of work, then they will transition to a Merkle Tree proof of work algorithm, known as MTP. MTP is a unique memory hard algorithm that aims to solve several problems. Memory hard algorithms help prevent the development of ASICs which lead to centralized mining farms. Memory hard algorithms also prevent the use of botnets infecting computers for mining purposes. If a botnet was using up multiple gigs of memory, you’d be likely to notice something is wrong. “The basic concept is that it should establish the same price/cost for a single computation unit on all platforms meaning that there is no single device that should gain a significant advantage over another for the same price hence promoting egalitarian computing.
