The emergence of Bitcoin, decentralized cryptocurrencies and the fundamental innovation blockchain have allowed for entities to trade and interact without a central trusted third party. This has led to a captivating research activity in multiple domains, across different venues, such as top security, distributed systems conferences, journals as well as a vibrant startup rush on this new technology. The first IEEE (under application) CRYPTO VALLEY conference on Blockchain Technology aims to unite interested scholars as well as industrial members from all relevant disciplines who study and work in the space of blockchain technology. Suggested contribution topics include (but are not limited to) empirical and theoretical studies of: Anonymity and privacy issues and measures to enhance them Applications using or built on top of blockchains Atomic Swapping and cross blockchain communication Big Data and blockchain technology Bitcoin, Ethereum, Monero, ZCash protocol, other coins and extensions (cryptography, scripting/smart contract language etc.) Case studies (e.g., of adoption, attacks, forks, scams, …) Censorship Consensus protocols for blockchains Cryptocurrency adoption and economic impacts Decentralized Applications (Exchanges, Mining Pools, Trading Platforms) Developing countries adoption of blockchain Economic and monetary aspects Forensics and monitoring Formal Verification of Blockchain Protocols, Smart Contracts Fraud detection and financial crime prevention Governance Identity, Identification and trust in blockchain systems Implications for existing business models Interfacing fiat and cryptocurrencies Intermediates in different industries and their future Internet of things (IoT) and blockchain technology Legal implications of smart contracts Legal, ethical and societal aspects of (decentralized) virtual currencies, ICO/TGE New applications and business models for permissioned/permissionless blockchain Off-chain payment channels Peer-to-peer networks Permissioned (e.g. Hyperledger) and permissionless (e.g. Bitcoin) blockchains Privacy and anonymity-enhancing technologies Proof-of-work, -stake, -burn, and virtual mining Real-world measurements and metrics Regulation and law enforcement Relation to other payment systems Scalability and scalable services for blockchain systems Security of Blockchain Protocols Smart Contract Programming Languages and VM's Transaction graph analysis Usability and user studies Where does a blockchain makes sense? The conference solicits manuscripts that represent significant and novel research contributions. Submissions must not substantially overlap with works that have been published or that are simultaneously submitted to a journal or a conference with proceedings. Submissions should follow the IEEE Conference Proceedings Format format and should not exceed 10 pages, excluding references and well-marked appendices. There is no limit on the length of the references and appendices. Accepted papers will appear in the IEEE proceedings published by IEEE. Authors who seek to submit their works to journals may opt-out by publishing an extended abstract only. Short papers (4 pages or less including references and appendices) are also welcome and should be submitted with "(short paper)" in the title. All submissions will be reviewed double-blind, and as such should not contain author names, must be anonymous, no acknowledgments, affiliations, or obvious references.
