These companies and entities also act as increasingly powerful intermediaries that enable, authenticate and settle digital transactions– of property, currency, identity/reputation, and many other forms of digital data. Blockchain, or cryptographically-secured replicated databases, has the potential to decentralize the transfer of value over the Internet, creating secure, decentralized peer-to-peer economies of trust. By doing so, blockchain disintermediates traditional industries, taking out rent-seeking middlemen who levy taxes on end-users as verifiers, trust-providers or settlors of transactions. Imagine a currency without a central bank (Bitcoin), a portable digital identity without a centralized authenticator (uPort), or a peer-to-peer global file storage system without reliance on centralized cloud-based server providers (Filecoin). Thus far, the “blockchain revolution” has been powered by speculative investment and misunderstanding. But we at Dunya Labs believe that innovations in cryptographically secured, replicated networks are maturing, and the exploration of blockchain as a foundational technology is moving into a mature phase driven by research and execution. Many esteemed academics and cryptographers have joined the field, including Silvio Micali (Algorand), Benn Lynn of BLS Signature Scheme (DFINITY), Andrew Yao (Conflux), Xinmin Luo (DFINITY), Dan Boneh, and more. We are building a knowledge company that focuses on just research and execution. Our mission is to bring blockchain use-cases to market.
