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.
The bitcoin network is a peer-to-peer payment network that operates on a cryptographic protocol. Users send and receive bitcoins, the units of currency, by broadcasting digitally signed messages to the network using bitcoin cryptocurrency wallet software. Transactions are recorded into a distributed, replicated public database known as the blockchain, with consensus achieved by a proof-of-work system called mining. Satoshi Nakamoto, the designer of bitcoin claimed that design and coding of bitcoin began in 2007. The project was released in 2009 as open source software. The network requires the minimal structure to share transactions. An ad hoc decentralized network of volunteers is sufficient. Messages are broadcast on a best effort basis, and nodes can leave and rejoin the network at will. Upon reconnection, a node downloads and verifies new blocks from other nodes to complete its local copy of the blockchain. A bitcoin is defined by a sequence of digitally signed transactions that began with the bitcoin's creation, as a block reward. The owner of a bitcoin transfers it by digitally signing it over to the next owner using a bitcoin transaction, much like endorsing a traditional bank check. A payee can examine each previous transaction to verify the chain of ownership. Unlike traditional check endorsements, bitcoin transactions are irreversible, which eliminates the risk of chargeback fraud. Although it is possible to handle bitcoins individually, it would be unwieldy to require a separate transaction for every bitcoin in a transaction. Transactions are therefore allowed to contain multiple inputs and outputs, allowing bitcoins to be split and combined. Common transactions will have either a single input from a larger previous transaction or multiple inputs combining smaller amounts, and one or two outputs: one for the payment, and one returning the change, if any, to the sender. Any difference between the total input and output amounts of a transaction goes to miners as a transaction fee. In 2013, Mark Gimein estimated electricity consumption to be about 40.9 megawatts (982 megawatt-hours a day). In 2014, Hass McCook estimated 80.7 megawatts (80,666 kW). As of 2015, The Economist estimated that even if all miners used modern facilities, the combined electricity consumption would be 166.7 megawatts (1.46 terawatt-hours per year). To lower the costs, bitcoin miners have set up in places like Iceland where geothermal energy is cheap and cooling Arctic air is free. Chinese bitcoin miners are known to use hydroelectric power in Tibet to reduce electricity costs. Various potential attacks on the bitcoin network and its use as a payment system, real or theoretical, have been considered. The bitcoin protocol includes several features that protect it against some of those attacks, such as unauthorized spending, double spending, forging bitcoins, and tampering with the blockchain. Other attacks, such as theft of private keys, require due care by users.
