  • Blockchain consensus algorithms explained by a developer (with Jack Tanner)

    ******* Registration (required!) via https://www.eventbrite.com/e/blockchain-consensus-algorithms-explained-with-bitcoin-nxt-ethereum-ripple-eos-and-komodo-tickets-68585877205 ******* This event will be technical in nature and intended for technical professionals and developers with some previous understanding of blockchain concepts. It is offered by Jack Tanner https://jackandtheblockstalk.com/ - nomad developer and educator­ and made possible with the support of https://workonblockchain.com/ . Main presentation: Blockchain consensus algorithms We will explore several different mechanisms for achieving consensus for blockchains and distributed ledges and their characteristics. Rough agenda: * Proof of Work - Bitcoin case study * Proof of Stake - NXT and Ethereum case study * Delegated Proof of Stake - EOS case study * Proof of Authority - Ripple case study * We might talk about LPOS (Tezos), POI (NEM) or DAGs (IOTA) if time permits and if we can prepare in time * Block commitment rounds - Bitcoin, EOS, Cosmos case study Speaker: Jack Tanner Jack is a passionate advocate for Blockchain Technology and loves teaching technical concepts in an understandable way. Jack is a Blockchain Developer and Cryptocurrency Specialist. He recently completed a Masters in Computer Science at Imperial College London and a previous student at The Blockchain Connector Ethereum developer workshop. He currently works as a senior blockchain developer on the Indorse platform, and has been involved in numerous blockchain projects and education events. From Brisbane, Jack is enthusiastic to share his knowledge with his home two before returning to London. Second presentation: Delayed Proof of Work This talk will be about Delayed Proof of Work, a consensus mechanism designed and executed by the Komodo team and available for all under the MIT license. Delayed Proof of Work, dPoW, is an interchain mechanism which continuously secures blockchains into Komodo and Bitcoin. That way smaller blockchains running dPoW are independent and secure while recycling Bitcoin’s hash rate. With dPoW we can build the multi-chain future. Speaker: Bart van Maarseveen Bart van Maarseveen (https://bart.vanmaarseveen.net/) is passionate on decentralisation and open source. He thinks we should always strive to reach maximum decentralisation as power tends to corrupt, always. Bart consults about blockchain solutions and is an entrepreneur in the blockchain space for some time. He is active as co-founder of communities like Blockbar (The Hague) and Blockdam (Amsterdam) and of the mobile DEX wallet CoinCollect. Schedule: 5:45:6:00 - networking with drinks and nibbles 6:00-8:00 - main presentation 8:00-8:30 - second presentation 8:30 - networking with drinks Event Organisers: Jack Tanner https://jackandtheblockstalk.com/ https://twitter.com/jackandtheblock https://www.linkedin.com/in/jack-tanner/

  • [Workshop] Privacy Infrastructure for the Decentralized Web: Secure Computation

    Join us for an active workshop in The Hague, to explore use cases for Secure Computing. We will follow a new meetup formula where we join the Copenhagen and Cape Town meetup groups (comfortably in the same time zone!), have an introductory plenary talk, followed by local workshop groups that report back to the plenary in the end. This requires strict planning and time coordination, so the schedule will be: 18:00 Open doors 18:30 Local introductions 18:45 Introduction to Event by Troels Plenge (Copenhagen) 18:50 Talk by John 'Tux' Pacific (USA) 19:35 Introduction to Workshop session by Troels Plenge 19:40 Workshop in Groups 20:10 Group presentations 20:30 Online event ends - local networking Questions beforehand or want to introduce yourself? Join the Telegram chat at https://t.me/joinchat/G2ov-BWiFRz43jkodBp6hw ************************************************************************** Description ************************************************************************** (See https://docs.google.com/document/d/12e95wRy0rj4jtFfS08y_7ZY5BFsoVktWwaTazCosZkc/edit for the living document) Secure Computation allows for secure, privacy-preserving artificial intelligence. Projects like openmined.org started to research and discover how you could apply machine learning on your personal data without exposing your data to others. Those principles are now starting to be adopted by many projects. In this session we will have a talk by John 'Tux' Pacific, who is a Cryptography Engineer with NuCypher, where they work at building Privacy Infrastructure for the Decentralized Web. He will take us through the different technologies available to achieve secure computation, and explain use-cases of projects applying these technologies. After the session we will have a workshop, where the participants will work in groups (3 to 6 ppl) to find use cases, where these concepts can be applied. This workshop will be hosted as part of the “Global Eth Organizer” network, where world class speakers are broadcasting live to multiple meetup locations worldwide, while the workshop sessions are hosted locally. PARTICIPATING MEETUPS INCLUDE Copenhagen Ethereum Meetup https://www.meetup.com/Copenhagen-Ethereum-Meetup/events/261347503/ Cape Town Ethereum Meetup https://www.meetup.com/Cape-Town-Ethereum-Meetup/events/261346972/ ETH DEV NL - http://ethereum.nl
