TUM Blockchain Salon

Aims

  • Exploring core technologies for security, scalability, and privacy in Blockchain systems
  • Discussing applications and solutions with requirements met by these core technologies, and to which extent these technologies provide value
  • Exchange on methods for assessment of P2P layer, smart-contract security, and cryptographic innovations
  • Bridge academia, industry, and students and introduce recent topics from various layers of the Blockchain stack and ecosystems

Topical Scope

  • Individual layers of Blockchain Protocols spanning hardware, peer-to-peer network, consensus, execution layers, applications, and ecosystems
  • Innovative scalability and privacy technologies, such as zero knowledge proofs
  • Design, verification, and implementation of smart contracts logic
  • Methods and tools for performance assessment
  • Overview of possible optimization solutions and their applicability to blockchain solutions
  • Applications and use-cases in Web3.0 and Blockchain Technologies and open challenges
