A Department of Decentralization event - https://dod.ngo The video features Sergei, a protocol researcher at Vaku, who will discuss the Vaku platform, its relevance for hackathon projects, and demonstrate how to run a node. He begins by contrasting the lack of privacy in Web2 and Web3 communications, emphasizing the need for a secure communication layer in Web3. Sergei explains that Vaku is not a blockchain or messenger but is a privacy-focused messaging protocol for Web3 apps. He details that Vaku can be used for various applications beyond messengers, such as private voting systems, off-chain state machines, multi-signature wallet coordination, and layer 2 roll-up coordination. The talk aims to provide motivation to explore Vaku's documentation and use it in hackathon projects. Additionally, Sergei introduces the design principles of Vaku: being generalized for any data exchange, permissionless participation, and allowing anyone to join and relay messages within its network.
