A written summary by Sathya Peri of the 2018 MIT Bitcoin Expo talk given by Will Warren.
Most decentralized cryptocurrencies today rely on the proof-of-work consensus protocol pioneered by Bitcoin. While an ingenious design, proof of work has several downsides, including its enormous energy consumption. A promising candidate for replacing proof of work is proof of stake.
We present Ouroboros (CRYPTO ‘17), the first blockchain protocol based on proof of stake with rigorous security guarantees. We detail how Ouroboros operates, the provable guarantees it provides and the main challenges in proving these guarantees.
Speaker: Peter Gaži
Date: Monday, January 8, 2018
Time: 9:00 AM – 10:00 AM
Location: MIT 32-141 (Stata Center, 32 Vassar Street, Cambridge, Room 141)
The club had its first Open Discussion of the semester on 11/14. Ryan Stirling moderated the discussions centred around Bitcoin Scaling.
Block propagation time, its relation to the block size and to the incentives for a miner, adversarial model, etc. were a few among several other related topics discussed among a room full of attendees. The full minutes of the meeting can be read at this link.
We hope to have more open discussions and presentations in the coming weeks. Our meetings are always open to the public; every Tuesday, 8 PM, at 5-217. Hope to see you at the next meeting.

LBRY is a decentralized digital marketplace that uses blockchain technology to fix two of the biggest flaws of BitTorrent: discovery and monetization. Via an entirely peer-to-peer network, LBRY maps URLs like lbry://itsadisaster to the Hollywood film starring David Cross and Julia Stiles (film company Oscilloscope Laboratories is one of their early partners).
Come meet the CEO, Jeremy Kauffman, for an introduction to the LBRY protocol. LBRY is offering paid internships both this semester and next. LBRY is entirely open source. You can explore the source here or read more here.
LBRY will also be offering beta invite codes and credits to anyone who attends (though if you’re even moderately clever there’s no need to wait for a code to start using it 😉

Matt Liston from Gnosis is visiting to talk to us about prediction markets and their applications, Futarchy, and their upcoming crowdsale. A high level overview of the Gnosis prediction and oracle market will be presented along with a survey of applications including forecasting, betting, action incentive, governance, and insurance. The presentation will conclude with crowdsale and DAO structuring details and an open Q&A.
Hosted by ConsenSys and the MIT Bitcoin Club. Refreshments will be provided!

Airbitz has pioneered Edge Security–a new way to secure your most valuable data that’s easy enough for anyone to use. They are best known for their feature rich Bitcoin mobile app which is built on the Edge Security platform and allows users to buy, sell, spend, and secure their bitcoin.
Paul Puey is the CEO and co-founder of Airbitz. Paul is a proud Electrical Engineering and Computer Science graduate of UC Berkeley with a wide range of technical skills from low-level 3D graphics engineering to development of custom web CMS systems, even before people knew what a CMS was. He held lead engineering positions with Nvidia and Chromatic Research, but most recently owned and operated several non-technical small businesses throughout California. There he learned the importance of the intersection of people, business, and technology.
Instead of keeping up with a pile of usernames and passwords, imagine if you could access your online accounts with one private ID. It’s called BitID, and it’s available today. BitID uses the same cryptography that Bitcoin uses to prove the ownership of a particular key, even when the environment is unreliable or untrustworthy. With BitID, you can use your Bitcoin wallet to sign a message with your private key to login to online accounts. No sensitive, targetable personal information is ever exchanged.
Paul will be presenting BitID via video call.
