A peer-to-peer network(P2P) is a decentralized model that includes a group of nodes which save and share recordscollectively; here, each node or device acts as individual peer.The communication in P2P does not have any central control or administration, and all the nodes in the network have equal rights in handling the tasks. This architecture is categorized into three different networks:Structured P2P, unstructured P2P and hybrid P2P networks. In the structured P2P systems, all the nodes or devices will be organized and can search the desired data efficiently in the network. In unstructured P2P systems, the network connection will happen randomly, whereas the hybrid models work by combining both client server and P2P models (Verheye, et.al, 2020). Nowadays, P2P is the foundation for cryptocurrencies and an important part of the blockchain industry.

Peer-to-peer (P2P) systems enable users to easily share files, by downloading data simultaneously from multiple sources and sharing many different file types. Good and Krekelberg (2003) illustrate HCI problems with P2P file-sharing systems such as KaZaA. KaZaA, the most popular and widely used P2P tool in 2003, had an average of 120 million downloads worldwide and 3 million users online at any given time during the course of the study. Good et al. conducted a user study of KaZaA and found that a large proportion of users unwillingly share personal and private files, leaving them at risk of being taken advantage of through unknown exposure of PI. The majority of the users in the study were unable to correctly determine the files they were sharing. Many thought they were sharing no files when they were actually sharing all the files on their hard drive.

P2P systems are distributed systems able to form self-organizing overlay networks to provide efficient search/distribution of data items [1]. By introducing the concept of peer, i.e., an entity that provides and, at the same time, consumes resources/services offered by others entities, P2P systems go beyond the traditional client/server paradigm thanks to its features of self-organization, fault-tolerance, and high scalability. In the last years, the P2P paradigm has gained popularity as a consequence of the diffusion of Internet file sharing applications like Napster [2], Gnutella [3], and Emule [4], which have allowed millions of users to share files in a decentralized manner.

During the COVID-19 restrictions, solutions were sought to advance engagement with online experiences using interactive cloud-based collaborative web platforms, including Padlet6 (n.d.). Such platforms allow users to upload and share files to virtual bulletin boards in real time. With regards to Padlet, files are easily accessible, can be anonymous and have the advantage of providing instant visual representation of posts, without having to scroll through discussion threads (Ellis, 2015). Platforms such as Padlet allow PSTs to anonymously post their solutions online, think about their strategy in their own time, and visually see all the class’s responses (Fisher, 2017). For example, Figure 4 shows an example of Padlet responses to the Number Talk challenge: ‘Do the following in your head 25 + 89, record your thinking for solving the problem and post to Padlet’.

After yet quite different from Facebook, YouTube was made public in 2005. The users can upload and share videos to the public or private. These social media have become popular because users can easily discover new things, greatly impacting the entertainment industry (Stokel-Walker 2019).
