LBRY (/ˈlaɪbrɛri/),[4] is a blockchain-based file-sharing and payment network that powers decentralized platforms, primarily social networks and video platforms. LBRY's creators also created Odysee, an open-source video-sharing website that uses the network, and that was split into a separate company on October 1, 2021.[4][5][6] Video platforms built on LBRY, such as Odysee, have been described as decentralized alternatives to YouTube.[7] The company has described Odysee and other platforms it has built utilizing its LBRY protocol as platforms for free speech and lightly moderates content, including removing pornography or the promotion of violence and terrorism.[4] LBRY's CEO is Jeremy Kauffman,[8] a libertarian activist[9] who was inspired to create LBRY to "provide people with choices for content," implicitly critical of the curated choices provided by YouTube.[10]
The LBRY protocol is a decentralized file-sharing and payment network built using blockchain and BitTorrent technology.[11] It allows anyone to create an account and register content that cannot be deleted by the company.[12] LBRY uses BitTorrent technology to serve content without relying on their own servers by using peer-to-peer file-sharing.[13] Creators can record video content to the LBRY blockchain, as well as other digital content including music, images, podcasts, and e-books.[11] The LBRY projects are open source.[11]

Free, open-source FTP client FileZilla, which has been piloting the Storj decentralized storage for nearly a year, had been making money through its free file-sharing service, which is hosted on SourceForge.net. (It pitches users third-party software or offers to let them make money by testing a new web or mobile application. In turn, FileZilla shares revenue with the third-party software vendors.)
The idea of using P2P networks to aggregate computer resources is not new. In the early 2000s, BitTorrent opened as a distributed file-sharing service and grew to handle more than half of the internet's file-sharing bandwidth.

This study discusses how blockchain-based sharing services can contribute to smart cities based on a conceptual framework. We hope it can stimulate interest in theory and practice to foster discussions in this area.
As such, to grasp the effects of emerging blockchain technology on the growth of smart cities, it calls forth the use of an observation perspective to identify their essential elements. To address this problem, we propose a triangle framework of human, technology, and organization to identify the features of smart cities from the angle of the sharing economy. We apply this framework to analyze the influence of blockchains on building smart cities. The rest of the paper is arranged as follows. In Section Smart cities and the sharing economy , we explore the relationship between the sharing economy and smart cities. We propose the aforementioned triangle framework in Section A conceptual framework of smart cities from a sharing economy perspective . In Section Blockchain-based sharing services: Toward smart cities , we analyze the features of the management and computing of blockchain-based sharing services within the framework and consider what blockchains may contribute to smart city development. In Section Conclusions , we draw our conclusions.
The sharing economy has created a number of opportunities for smart cities in terms of improving asset utilization and effectively reducing transaction costs and waste (Tedjasaputra and Sari 2016). Improving the use of assets implies numerous positive consequences, for instance, energy saving and congestion decreasing. While sharing goods and services in marketplaces has a long history, and old-fashioned face-to-face sharing still happens in communities everywhere, Internet intermediaries can now support these transactions and match supply and demand in real time on a large scale. On websites, people can find rooms to stay in (Airbnb, Roomorama), as well as for using tools (SnapGoods), cars, bikes (RelayRides, Wheelz), and ad hoc taxi services (Uber, Lyft). These websites unlock the value inherent in sharing spare resources as two-sided platforms, and offer many advantages to attract the two groups via network effects (Eisenmann et al. 2006).
To understand the blockchain solution, we summarize the features of the management and computing of blockchain-based sharing services via the triangle framework of service orientation (Zhao et al. 2008). Altogether, there are six types of service relationships among human, technology, and organization. As shown in Fig. 3, where each arrow indicates a type of service relationship, the management of blockchain-based sharing services mainly deals with relationships involving people, while the computing of blockchain-based sharing services mostly relates to relationships involving technology.
Due to the change in the trust model of blockchain-based system, the service relationship between the elements of human and organization in blockchain-based sharing services has become democratized. In blockchain-based sharing services, trust is not placed in an individual, but rather distributed across the entire population. The use of central authorities is replaced by a community of peers in the form of a peer-to-peer network; no one can unilaterally take actions on behalf of the community. In such a democratized context, governments cannot manipulate an election by coercing individuals, and corporations cannot unilaterally break the rules of the system.
The distributed nature in a service relationship between technology and organization is an important aspect of the computing of blockchain-based sharing services. Distributed computing and distributed algorithms allow democratized nodes in a blockchain to reach a consensus. In a distributed system, different nodes need to prove that they are working toward the same goal and ensure consistency. Bitcoin creator Satoshi Nakamoto proposed the proof of work (POW) mechanism to create distributed consensus in a process of repeatedly running hashing algorithms to validate electronic transactions, or so-called bitcoin mining (Nakamoto 2008). According to IBM (IBM 2015), adopting distributed computing to process hundreds of billions of IoT transactions that occur daily can significantly reduce costs associated with installing and maintaining large amounts of centralized data; thus, blockchain technology has democratized devices in terms of distributed computing, which will ensure the future of the IoT.
The Filecoin project is open source and encourages storage providers, consumers and developers to build apps on top of its file system. It is worth noting, however, that the Lotus nodes used by Filecoin are only supported on Linux and MacOS. Windows is not yet supported.
The software uses Reed-Solomon erasure coding to ensure redundancy and make it possible to recover a file from only 10 of its segments. The software also uses the open source Threefish algorithm to encrypt the segments before sending them to the storage hosts. Renters use Siacoin to purchase storage, and hosts use Siacoin as collateral when storing files.
Open source cloud storage data is available and accessible 247 from a remote location. Many organizations are using their own solutions to cloud storage and data privacy. You can access data stored on cloud storage using mobile apps or web based systems. Businesses organizations are shifting from the local storage drive to self hosted cloud storage. Cloud storage has made data sharing and collaboration easier. Now many people are using open source self hosted cloud storage tools for file sharing purposes. Cloud storage field is under active development because of potential threats including loss of data or information, data hacking and other attacks.
