The workshop on cryptographic tools for blockchains aims at discussing cryptographic mechanisms and their use in distributed ledger technologies. The workshop solicits submissions describing current work addressing decentralized cryptocurrencies and distributed ledger technologies, including cryptographic schemes and techniques as well as their applications in blockchain protocols, analytical results, work on systems, and/or position papers.

Topics of interest include, but are not limited to the following techniques and their applications in blockchains:

• Non-interactive zero-knowledge proofs
• Threshold cryptosystems including signatures and encryption
• Verifiable credentials
• Consensus protocols
• Fully homomorphic encryption
• Multi-party computation
• Privacy-preserving smart contracts
• Censorship resistance
• Security of peer-to-peer networks
• Post-quantum cryptography and crypto-agility in blockchain
• Digital Forensics and Incident Response in blockchain 

Submissions should be written in English, formatted in single-column letter-sized or A4-sized format, and prepared as a PDF file. Submissions have to include: a title, author names and affiliations. Additional material such as a more detailed description or presentation slides may be added in an optional appendix. Papers must be submitted via the submission page. There will not be formal proceedings or other forms of official publications of the accepted papers. Authors are encouraged to submit works already published at or submitted to other venues.
