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.

The MIT Bitcoin Club provides forums where Bitcoin-related ideas, projects, programs, events, and businesses can be studied, discussed, and developed. We often get questions from Bitcoin enthusiasts and experts on how they can get involved with the Club. Here are five ways you can do so:-
1. Subscribe to our newsletter
Our weekly newsletter is the central source of information which announces the times and agenda for all our events. Additionally, the newsletter shares details of important Bitcoin and Blockchain related events/news which might be useful for the members. Subscribing to the newsletter should be your first step in getting involved.
2. Attend our meetings
Our core event, the weekly Tuesday meetings are always open to the public. Come attend them every Tuesday at 8 PM and participate in the discussions. We meet throughout the fall and spring semesters. Meetings are typically held in MIT Building 5, room 217.
3. Join our Slack Channel
We have a very active channel on Slack where you can share your questions and answers 24/7/365. Join it now.
4. Follow us on Social Media
Follow our twitter handle @MITBitcoinClub and like our Facebook page to get regular updates about our events and news related to Bitcoin.
5. Visit our Blog
Although we may not post blog posts very regularly, it is not a bad idea to check the blog once in a while. Some of the old blog posts are very interesting and informative.
Always feel free to send a message to us if you need any information.
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 😉
The Electronic Frontier Alliance is a grassroots network of community and campus organizations across the United States working to educate our neighbors about the importance of digital rights. As a member organization of the EFA, MIT Bitcoin Club believes that technology should support the intellectual freedom at the heart of a democratic society. In the digital age, that entails advancing:
People should be able to speak their minds to whoever will listen.
Technology should be trustworthy and answer to its users.
Technology should allow private and anonymous speech, and allow users to set their own parameters about what to share with whom.
Technology should promote progress by allowing people to build on the ideas, creations, and inventions of others.
Access to Knowledge:
Curiosity should be rewarded, not stifled.

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!
You can visit the meetup page for this event, or checkout the Gnosis website as they launch their beta.

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.
