Call for Proposals

The second Scaling Bitcoin Workshop will take place 8th  October 2016 - 9th  October 2016 at the Politecnico di Milano Piazza Leonardo da Vinci, 32 20133 Milano - Italy. We are accepting technical proposals for improving Bitcoin performance including designs, experimental results, and comparisons against other proposals. The goals are twofold: 1) to present potential solutions to scalability challenges while identifying key areas for further research and 2) provide a venue where researchers, developers, and miners can communicate about Bitcoin development.

We are accepting two types of proposals: one in which accepted authors will have an opportunity to give a 20-30 minute presentation at the workshop, and another where accepted authors can run an hour-long interactive workshop.

Topics of interest include:

  • Improving Bitcoin throughput
  • Layer 2 ideas (i.e. payment channels, etc.)
  • Security and privacy
  • Incentives and fee structures
  • Testing, simulation, and modeling
  • Network resilience
  • Anti-spam measures
  • Block size proposals
  • Mining concerns
  • Community coordination

All as related to the scalability of Bitcoin.

Important Dates

  • 2016-09-09 23:59 UTC - Last day for submission
  • 2016-09-23 23:59 UTC - Last day for notification of acceptance and feedback

Formatting

We are doing rolling acceptance, so submit your proposal as soon as you can. Proposals may be submitted as a BIP or as a 1-2 page extended abstract describing ideas, designs, and expected experimental results. Indicate in the proposal whether you are interested in speaking, running an interactive workshop, or both. If you are interested in running an interactive workshop, please include an agenda.

Proposals should be submitted to proposals@scalingbitcoin.org by 2016-09-09 23:59 UTC.

All talks will be livestreamed and published online, including slide decks.

Workshop

How do the Workshops work?

  • Events are live-streamed with remote participation facilitated via IRC for parallel online discussion and passing questions to the event.
  • These workshops aim to facilitate the existing Bitcoin Improvement Proposals process. Most work will be done outside of the workshops in the intervening months. The workshops serve to be additive to the design and review process by raising awareness of diverse points of view, studies, simulations and proposals.
  • Travel, venue details, accommodation recommendation are available below.
  • Please see the FAQ section below, it should answer most other questions.

FAQ

  • What does it cost?

    To encourage continuity of ongoing discussions, all Phase 1 and 2 participants are invited to Scaling Bitcoin 2016 "Retarget" in Milan at $150 USD (same as for Montreal and Hong Kong). From August 15th, tickets may be available at $300 USD/ticket -- subject to availability.

  • I need some sort of document for a travel visa

    (Info: http://vistoperitalia.esteri.it/home/en) You are responsible for figuring out your own personal visa requirements to enter Italy. If you need a letter of invitation, then please correspond with simona.macellari at theinnovationgroup.it (please include your name as in your passport, title and correspondence address).

  • I can’t go but I want to participate!

    The event will be livestreamed, and you will be able to participate via IRC. Although it is naturally easier to participate in person, everyone at the event will have a desk in front of them and will be encouraged to join in online discussions with global participants who are viewing the live stream. It is also important to understand that no decisions are to be made at the workshop. (read more below)

  • How do I give a presentation?

    You can submit your proposal to proposals@scalingbitcoin.org (see CFP above). If you’ve worked on research, we recommend that you post the results, including papers, simulation results, and source code, to the bitcoin-dev discussion list. Depending on the quantity of accepted presentations, the workshop will allot a fair amount of time to each presenter. If people have substantially overlapping plans, they may be suggested to merge. Publishing a paper is NOT required—if you have a good presentation plan, you can propose a detailed summary.

  • Why Milan?

    The third workshop is being planned for Milan, Italy to make it easier for the European Bitcoin community members to attend. Milan is an international and avant-garde city with a charming Bitcoin community of developers and adopters. Together, BlockchainLab and AssoB.it, have created a vibrant environment for Bitcoin related starts-ups where they have fostered inclusive, rigorous and amicable technical discussions.

  • Are any decisions made at the workshop?

    Absolutely no decisions are made at workshops, as this would run the risk of being rushed and unfair to the global community unable to attend in person. The workshop is about raising awareness of issues and proposals, finding common ground, and encouraging public discussion within the existing mechanism of technical progress through the Bitcoin Improvement Proposal process.

  • Will there be a debate?

    There will probably be no debate, and the workshop organizers and participants will be operating with the goal of making the event low-stress and non-confrontational. The intent of the workshops are to showcase diverse points of view and promote open-mindedness in order to improve our collective understanding of how to improve Bitcoin’s scalability. In-person debates could too easily do a disservice to the future of Bitcoin in being about solidifying simplified positions for the purpose of winning political points. It would be unreasonable to entrust the safety and security of the future of Bitcoin to smooth talking at a one-time event rather than deliberate technical study with time for the global community to weigh in.

  • Can we discuss governance of the Bitcoin projects at this workshop?

    Scaling Bitcoin Workshops are focused on raising technical awareness of scalability issues, simulations and proposals to improve scalability. For now the participants want this to be entirely focused on the science and engineering, which is how Open Source Software development has proven to deliver excellence.

  • Future Workshops? Workshop BIP?

    We aim to host a Scaling Bitcoin Workshop once per year. If you would like to host next year's event please complete the following form https://goo.gl/forms/kAqlSE3MqJL3hkI72

  • Are there Vegetarian, Gluten-Free Options for the Food?

    Yes. Please email contact@scalingbitcoin.org if we can be of any assistance.

  • Is there Wheel Chair Access to these social events?

    Yes, all venues have been audited and are wheel-chair friendly. Please email contact@scalingbitcoin.org if we can be of any assistance.

  • How do you translate Bitcoin terminology to Italian?

    Bitcoin terminology is available at: http://scalingbitcoin.org/technical-terms

    Il Codice di Condotta in Italiano è reperibile qui
