The first Workshop on *Advanced Security of the Digital Twin and the Metaverse (ASDTM)* http://intelligenttech.org/BCCA2022/Workshops/ASDTM2022/ *In Conjunction with* *The Fourth International Conference on Blockchain Computing and Applications (BCCA 2022)* 5-7 September 2022 (San Antonio, Texas, USA) http://intelligenttech.org/BCCA2022/index.php The real world is surrounded by people, buildings, hospitals, factories, businesses, vehicles, entire cities, and the billions of devices that provide various services and connect us to each other and to this world. The Digital Twin provides an advanced solution to replicate this physical world into a digital clone of it. It is bound to the physical world in real-time allowing it to run simulations on, and understand system patterns, and using AI it allows to learn, predict, and act to improve the provided services (i.e. to save time and money, reduce carbon, to preserve natural resources, to improve safety, etc.). This wave of innovations trends to an interconnectedness that enables the metaverse. In other words, the metaverse provides an exciting immersive experience in a 3d world providing a flexible manner to interact and collaborate with the real-world digital clone. Everything modeled in the real-world Metaverse nears the status of its physical twin including interactions and relations between everything else. To this end, a huge amount of data has to be collected and managed to put heavy challenges on the networking and computing systems. On the other hand, these technologies have strict boundaries related to the security and the privacy of the collected data. By applying the power of the blockchain, new ways to secure, store and manipulate the data can be provided to eliminate boundaries of what can be provided. The potential is limitless to track, manage data and create patterns, and trends, and detect anomalies. The purpose of this workshop is to elaborate on and emphasize the key aspects to secure the metaverse. The workshop welcomes original research and innovative solutions on the above subjects as well as the case studies that explore the potential exploitation of blockchain in the Digital Twin and the Metaverse. Research may cover and focus on either the fundamental methodological studies or the use case and application demonstrations. Topics of interest include, but certainly not limited to: · Blockchain in the metaverse · Blockchain in the digital twin · Edge computing for Internet of Metaverse · Network security of the metaverse · Digital twin and Metaverse privacy · Consensus and mining algorithms suited for the metaverse · Blockchain-based Controlled mobility and QoS in the metaverse · Cybersecurity in the metaverse *Organization Committee:* · Ouns Bouachir, Zayed University, UAE · Müge Erel-Özçevik, Celal Bayar University, Turkey *Important Dates:* · Workshop Papers Due: * 15 July 2022 25 July 2022* · Papers Acceptance Notification: *1 August 2022* · Final Camera-Ready Paper Due: *15 August 2022*
