MISSION:
-----------------------------------------------------------------------------------------------
Blockchain technology is renowned for its decentralized ledger system, which ensures secure, transparent, and tamper-proof transactions across distributed networks. It allows information to be shared and verified by a network of participants without a central authority to manage or validate the data. Once added to the Blockchain, records are stored in a cryptographically secured, immutable, and chronological sequence, rendering any alteration virtually impossible. This structure significantly enhances security, improving trust among participants. The Complex Network perspective can be applied to real-world systems (i.e., social networks, criminal networks, biological networks, power grids, air transports, and inter-bank communications) by structuring them in nodes and edges. The synergy between Blockchain and Complex Network theory enhances the reliability and authenticity of connections across decentralized networks, ensuring data exchanges are secure, tamper-resistant, and verifiable. This emphasis on trusted connectivity will provide a stronger foundation for secure distributed systems that encourage greater trust in decentralized applications and networks. By exploring the structural features of Blockchain networks through the lens of Complex Network theory, this Workshop investigates potential vulnerabilities, enhancing the design of more secure consensus mechanisms, and integrating graph concepts to improve efficiency, scalability, and transaction processing speed and throughput.

PAPER SUBMISSION:
-----------------------------------------------------------------------------------------------

NetBlock4TC accepts contributions 3 types of contributions:
1. Long papers (not previously published work) (12 pages)
2. Short papers (not previously published work) (8 pages)
3. Extended abstracts (about published or unpublished research) (2 to 4 pages).

The submission guidelines valid for the workshop are the same as for the FRCSS conference.
They can be found at: https://iutdijon.u-bourgogne.fr/ccs-france/submissions/


PAPER ACCEPTANCE AND PROCEEDINGS INCLUSION:
-----------------------------------------------------------------------------------------------

All accepted papers will be presented at the workshop.
However, inclusion in the official conference proceedings edited by Springer is subject to a final quality check conducted by the conference organizers.

1. Long papers (12 pages) and short papers (8 pages):
- May be included in the proceedings after the final quality check.
- If a paper does not meet the publication standards, it will still be accepted for workshop presentation but not included in the proceedings. Authors of these papers may submit an extended abstract for inclusion in the Book of Abstracts.

2. Extended abstracts:
- Will not be reviewed for proceedings inclusion but will be automatically published in the Book of Abstracts.

Authors will be notified separately regarding the final status of their paper in the proceedings.

Selected submissions of unpublished work will be invited for publication in special issues of partner journals as Applied Network Science published by Springer Nature or Frontiers in Big Data edited by Frontiers.
