What happens if there are bugs in Ethereum smart contracts? Are smart contract developers the new middlemen? What happened during the Bancor hack? Are Ethereum smart contracts and tokens secure? Could someone make centralised contracts still based on the ERC-20 standard?<br /><br />These questions are from the MOOC 9.6 and 9.7 sessions, and the July monthly Patreon session, which took place on March 23rd, March 30th, and July 28th 2018 respectively. Andreas is a teaching fellow with the University of Nicosia. The first course in their Master of Science in Digital Currency degree, DFIN-511: Introduction to Digital Currencies, is offered for free as an open enrollment MOOC course to anyone interested in learning about the fundamental principles. <br /><br />If you want early-access to talks and a chance to participate in the monthly live Q&As with Andreas, become a patron: <a href="https://www.patreon.com/aantonop" target="_blank" rel="nofollow">https://www.patreon.com/aantonop</a><br /><br />RELATED:<br />The Lion and the Shark: Divergent Evolution in Cryptocurrency - <a href="https://youtu.be/d0x6CtD8iq4" target="_blank" rel="nofollow">https://youtu.be/d0x6CtD8iq4</a><br />Investing in Education instead of Speculation - <a href="https://youtu.be/6uXAbJQoZlE" target="_blank" rel="nofollow">https://youtu.be/6uXAbJQoZlE</a><br />Ethereum, ICOs, and Rocket Science - <a href="https://youtu.be/OWI5-AVndgk" target="_blank" rel="nofollow">https://youtu.be/OWI5-AVndgk</a><br />Slush17 Panel: Farewell to Centralised Data - <a href="https://youtu.be/ul0aGzF-v5c" target="_blank" rel="nofollow">https://youtu.be/ul0aGzF-v5c</a><br />Blockchain vs. Bullshit: Thoughts On The Future of Money - <a href="https://youtu.be/SMEOKDVXlUo" target="_blank" rel="nofollow">https://youtu.be/SMEOKDVXlUo</a><br />Why I'm writing 'Mastering Ethereum' - <a href="https://youtu.be/So6WERp7vLY" target="_blank" rel="nofollow">https://youtu.be/So6WERp7vLY</a><br />Smart contract platforms - <a href="https://youtu.be/XU8Bc5oxneE" target="_blank" rel="nofollow">https://youtu.be/XU8Bc5oxneE</a><br />Impact of smart contracts on law and accounting - <a href="https://youtu.be/K-TRzuPwJCc" target="_blank" rel="nofollow">https://youtu.be/K-TRzuPwJCc</a><br />The legality of smart contracts - <a href="https://youtu.be/eKfnmxSmVF0" target="_blank" rel="nofollow">https://youtu.be/eKfnmxSmVF0</a><br />Gas and resource allocation - <a href="https://youtu.be/HwUJIGlHFes" target="_blank" rel="nofollow">https://youtu.be/HwUJIGlHFes</a><br />Intrinsic vs. extrinsic assets - <a href="https://youtu.be/KDtfFNZy9xg" target="_blank" rel="nofollow">https://youtu.be/KDtfFNZy9xg</a><br />Altcoins and specialisation - <a href="https://youtu.be/b_Yhr8h6xnA" target="_blank" rel="nofollow">https://youtu.be/b_Yhr8h6xnA</a><br />Ether, ICOs, and securities - <a href="https://youtu.be/guBNLSsnAiA" target="_blank" rel="nofollow">https://youtu.be/guBNLSsnAiA</a><br />Unstoppable code - <a href="https://youtu.be/AQx3E3F8Kz4" target="_blank" rel="nofollow">https://youtu.be/AQx3E3F8Kz4</a><br />Airdrop coins and privacy implications - <a href="https://youtu.be/JHRnqJJ0rhc" target="_blank" rel="nofollow">https://youtu.be/JHRnqJJ0rhc</a><br />Initial coin offerings (ICOs) - <a href="https://youtu.be/Q5R8KuxV4A0" target="_blank" rel="nofollow">https://youtu.be/Q5R8KuxV4A0</a><br />The token ICO explosion - <a href="https://youtu.be/vdaW8NtJXuQ" target="_blank" rel="nofollow">https://youtu.be/vdaW8NtJXuQ</a><br />ICOs and responsible investment - <a href="https://youtu.be/C8UdbvrWyvg" target="_blank" rel="nofollow">https://youtu.be/C8UdbvrWyvg</a><br />ICOs and financial regulation - <a href="https://youtu.be/Plu_WX3Gs8E" target="_blank" rel="nofollow">https://youtu.be/Plu_WX3Gs8E</a><br />ICOs, disruption, and self-regulation - <a href="https://youtu.be/yfjgcI8xX3A" target="_blank" rel="nofollow">https://youtu.be/yfjgcI8xX3A</a><br />Scams, gambling, and regulation - <a href="https://youtu.be/fTI88YrN1UE" target="_blank" rel="nofollow">https://youtu.be/fTI88YrN1UE</a><br />ICOs and pyramid schemes - <a href="https://youtu.be/8HYWWP1QU7Q" target="_blank" rel="nofollow">https://youtu.be/8HYWWP1QU7Q</a><br />Directed acyclic graphs (DAGs) and IOTA - <a href="https://youtu.be/lfgMnbb5JeM" target="_blank" rel="nofollow">https://youtu.be/lfgMnbb5JeM</a><br />Scaling and "Satoshi's vision" - <a href="https://youtu.be/Ub2LoTcYV54" target="_blank" rel="nofollow">https://youtu.be/Ub2LoTcYV54</a><br />"Blockchain, not Bitcoin " - <a href="https://youtu.be/r2f0HlaRdgo" target="_blank" rel="nofollow">https://youtu.be/r2f0HlaRdgo</a><br />Reflections on the last five years - <a href="https://youtu.be/NoCi64uaFT0" target="_blank" rel="nofollow">https://youtu.be/NoCi64uaFT0</a><br /><br />Andreas M.
