WORKSHOP HISTORY
=================

Since the emergence of Bitcoin in 2009, a wide array of
cryptocurrencies and blockchain-based systems have been introduced,
achieving varying degrees of adoption and success. While some of
these projects are incremental variations of Bitcoin, others present
novel consensus mechanisms, governance models, privacy-enhancing
technologies, or explore use cases beyond digital currency—such as
decentralized finance (DeFi), non-fungible tokens (NFTs),
decentralized autonomous organizations (DAOs), and scalable Layer 2
solutions. Despite these innovations, many proposed systems are
released as rapid prototypes or proof-of-concept implementations,
often lacking rigorous scientific evaluation.

This workshop aims to serve as a dedicated forum for researchers to
critically assess existing systems, explore emerging paradigms such
as zero-knowledge proofs, cross-chain interoperability, and
sustainable consensus, and propose robust frameworks that contribute
to a sound scientific foundation for the ongoing development of
blockchain technologies and next-generation decentralized systems.


The main topics include (but are not limited to):


* Anonymity and privacy in cryptocurrencies
* Blockchain Governance
* Privacy-preserving technologies
* Blockchain based trust systems
* Security analysis of existing cryptocurrencies
* Formal threat models in cryptocurrency systems
* Scalability and Performance Optimization
* Second Layer Solutions
* P2P network cryptocurrencies analysis
* Blockchain-based Identity Management
* Private transactions in blockchain based systems
* New usages of the blockchain technology
* Scalability solutions for blockchain systems
* Interoperability and Cross-Chain Technologies
* Distributed consensus and fault tolerance
* Blockchain Analytics and Forensics
* Blockchain Architecture and Consensus Mechanisms
* On-chain and off-chain code synergies
* Smart Contracts and Decentralized Applications (DApps)
* NFTs (Non-Fungible Tokens) and Digital Assets
* Decentralized Finance (DeFi)
* Blockchain Education and Adoption Challenges
* Quantum Computing and Blockchain Security




===================
