Cefriel has been working on distributed ledger technologies and smart contracts for years, creating an internal Blockchain Lab. The lab enables rapid development of end-to-end proof of concepts. Cefriel used the lab to develop proof of concepts for two projects - Videosign, which provides proof of publishing for digital media using blockchain, and Readerwallet, a decentralized blockchain-based digital wallet for micropayments. The document discusses Cefriel's approach to blockchain innovation, which involves learning through small experiments, developing minimum viable prototypes, and reducing risks through fast iteration.
