BRAINS 2023 Keynotes Speakers
Title: Blockchain Consensus Protocols, from Bitcoin to Ethereum 2.0.
Abstract: Bitcoin introduced a fully decentralized, peer-to-peer consensus protocol that enables secure transaction validation in an open network, marking a departure from previous Byzantine Fault Tolerant (BFT) protocols primarily designed for closed networks. An innovative combination of cryptographic and incentive mechanisms ensures the protocol’s robustness over the years. However, it’s important to acknowledge the considerable energy consumption of Bitcoin’s Proof-of-Work mechanism, which remains a significant concern. To address these energy concerns, there have been efforts to transition to more environmentally friendly solutions, such as Proof-of-Stake BFT protocols, like Ethereum 2.0. While these newer proposals hold promise in terms of energy efficiency, they come with complexities and ongoing issues in incentive design. In this talk I will present the main features and differences of Proof-Stake-BFT proposals with respect to Bitcoin, to appreciate their maturity and outline open issues and ongoing research challenges.

Title: Creating Business Value with a Decentralized Approach
Abstract: This keynote gives an insight into how technological concepts such as DLT are translated into business value at Deutsche Telekom. Today, also large corporations transact using intermediaries: banks, notaries, governments, stock exchanges, social networks, clearing houses, etc. These intermediaries provide the trust that is necessary when transacting with business partners. However, intermediaries create dependencies, cost, and slow down processes. T-Labs, the R&D unit of Deutsche Telekom, is researching the role of decentralized approaches such as blockchain and distributed ledger technology in the areas of telco with a focus in three key subtopics: communication networks, finance, and digital identity. The aim is to create solutions that overcome the drawbacks of centralized approaches and intermediaries. The keynote includes some concrete examples of past and ongoing projects.

Title: In education, from vision to pan European public and innovative transformation
Abstract: Last year, Vitalik Buterin said a « one sole token » would be convenient for non transferable assets such as a diploma ? You may wonder why more and more people in blockchain technologies speak about issuing and verifying diploma, skills and competences or even « micro-credits » in a wallet ? the fact is that higher education eco-system has quickly understood how to take the best advantages of the new ideas and technologies, in particular in the open source family.
