[Apologies, if you receive multiple copies] *The Third IEEE Conference on Blockchain Computing and Applications (BCCA 2021)* *NOV. 15 – 17, 2021 – TARTU, ESTONIA* http://intelligenttech.org/BCCA2021/index.php Blockchain is a revolutionary technology in decentralized systems that enables secure decentralized transaction processing while ensuring data privacy and authenticity. It is now playing a significant role in several areas such the Internet of Things, supply-chain management, manufacturing, cyber-physical systems, healthcare systems, and much more. Unlike centralized transaction processing solutions, blockchain uses a distributed ledger mechanism to record data transactions on multiple devices, this will prevent data breach, identity theft, and a plethora of cyber-related attacks, in essence, leading to a sustainability in data privacy and security. This conference aims at to attract work of both researchers and practitioners in the area of cyber-security to share and exchange their experiences and research studies in both academia and industry in the field of blockchain. Researchers are encouraged to submit original research contributions in all major areas, which include, but not limited to: · *Track 01: Artificial Intelligence and Machine Learning* o Blockchain based artificial Intelligent Systems applications in Computers and Communications o Blockchain based AI and Robotics Technologies o Blockchain based AI and cloud computing o Blockchain based Economic paradigms and game theory o Blockchain based Machine and Deep Learning of Knowledge o Blockchain based Distributed Knowledge and Processing o Blockchain based Humans-Agents Interactions / Human-Robot Interactions · *Track 02: IoT and Cyber-Physical Systems* o Blockchain-based IoT Applications and Services o Blockchain-based security for the Internet of Things and cyber-physical systems o Blockchain-based Internet of Things architectures and protocols o Blockchain in Cyber Physical Systems (CPS) o Blockchain-based application in Intelligent Manufacturing: Industrial Internet of Things, o Blockchain and Secure Critical Infrastructure with Industry 4.0 o Intelligent manufacture and management o Consensus and mining algorithms suited for resource-limited IoTs o Blockchain-based Controlled mobility and QoS o Blockchain-based energy optimization techniques in WSN o Blockchain-based Software defined networks · *Track 03: Big Data* o Blockchain in Data Fusion o Blockchain Analytics and Data mining o Distributed data store for blockchain o Distributed transaction for blockchain o Blockchain based Data Science and Data Engineering o Protocols for management and access using blockchains o Blockchain architectures tailored for domain-specific applications · *Track 04: Security and Privacy on the Blockchain* o Authentication and authorization in Blockchain o Applications of blockchain technologies in digital forensic o Privacy aspects of blockchain technologies o Blockchain-based threat intelligence and threat analytics techniques o Blockchain-based open-source tools o Forensics readiness of blockchain technologies o Blockchain Attacks on Existing Systems o Blockchain Consensus Algorithms o Blockchain-based Intrusion Detection/Prevention o Security and Privacy in Blockchain and Critical Infrastructure o Attacks on Blockchain and Critical Infrastructure o Blockchain and Secure Critical Infrastructure with Smart Grid · *Track 05: Blockchain Research & Applications for Innovative Networks and Services* o State-of-the-art of the Blockchain technology and cybersecurity o Blockchain-based security solutions of smart cities infrastructures o Blockchain in connected and autonomous vehicles (CAV) and ITS) o Blockchain Technologies and Methodologies o Recent development and emerging trends Blockchain o New models, practical solutions and technological advances related to Blockchain o Theory of Blockchain in Cybersecurity o Applications of blockchain technologies in computer & hardware security o Implementation challenges facing blockchain technologies o Blockchain in social networking o Performance metric design, modeling and evaluation of blockchain systems o Network and computing optimization in blockchains o Experimental prototyping and testbeds for blockchains All accepted papers in BCCA 2021 will be submitted to IEEEXplore, dblp and Scopus for inclusion. * Submission Link: *https://easychair.org/conferences/?conf=bcca2021 *Full paper Important Dates:* Submission deadline: July 1st, 2021 Notification of Acceptance: Sept 15th, 2021 Submission of camera-ready: Oct 8th, 2021
