Bitcoin Scalability Workshops<= /font>

In recent mont= hs the Bitcoin development community has faced difficult discussions of how= to safely improve the scalability and decentralized nature of the Bitcoin = network. To aid the technical consensus building process we are organizing = a pair of workshops to collect technical criteria, present proposals and ev= aluate technical materials and data with academic discipline and analysis t= hat fully considers the complex tradeoffs between decentralization, utility= , security and operational realities. This may be considered as similar in = intent and process to the NIST-SHA3 design process where performance and se= curity were in a tradeoff for a security critical application.


Since Bitcoin is a P2P currency with many stakeholders, it is impo= rtant to collect requirements as broadly as possible, and through the proce= ss enhance everyone=E2=80=99s understanding of the technical properties of = Bitcoin to help foster an inclusive, transparent, and informed process.


Those with technical interest are invited to participa= te in this pair of workshops with the following intent:


Phase 1: Scene setting, evaluation criteria, and tradeoff analysi= s. =C2=A0

Montreal, Canada: Septemb= er 12th-13th, 2015

Scalabil= ity is not a single parameter; there are many opportunities to make the Bit= coin protocol more efficient and better able to service the needs of its gr= owing userbase. Each approach to further scaling the Bitcoin blockchain inv= olves implicit trade offs of desired properties of the whole system. As a c= ommunity we need to raise awareness of the complex and subtle issues involv= ed, facilitate deeper research and testing of existing proposals, and motiv= ate future work in this area.


=

= The purpose of this w= orkshop is to discuss the general tradeoffs and requirements of any proposal to scale Bitcoin beyond its present limits. Session topics a= re to include the presentation of experimental data relating to known bottl= enecks of Bitcoin=E2=80=99s continued growth and analysis of implicit trade= offs involved in general strategies for enabling future growth.


This event will not host sessions on the topic of any specific= proposals involving changes to the Bitcoin protocol. Such proposals would = be the topic of a 2nd, follow-on Phase 2 workshop described below; this eve= nt is intended to =E2=80=9Cset the stage=E2=80=9D for work on and evaluatio= n of specific proposals in the time between the workshops.

Phase 2 will be planned out further as part of Phase 1 with input = from the participants.


Phase 2: Presentation = and review of technical proposals, with simulation, benchmark results. =C2=A0

Hong Kong, SAR, China: TBD Nov/= Dec 2015

Hopefully to be easier for the Chinese miners to attend, the second wo= rkshop pertaining to actual block size proposals is to be planned for Hong = Kong roughly in the late November to December timeframe.

<= font size=3D"2">

The purpose of this workshop is to present and review actual proposal= s for scaling Bitcoin against the requirements gathered in Phase 1. Multipl= e competing proposals will be presented, with experimental data, and compar= ed against each other. The goal is to raise awareness of scalability issues= and build a pathway toward consensus for increasing Bitcoin=E2=80=99s tran= saction processing capacity or, barring that, identify key areas of further= required research and next steps for moving forward.


Preliminarily, Phase 2 will be a time to share results from experiments = performed as a result of Phase 1 and an opportunity to discuss new developm= ents.


How do the Workshops work?=

  • Both events will be live-streamed with remote partic= ipation facilitated via IRC for parallel online discussion and passing ques= tions to the event.

  • These workshops aim to facilitate the existing Bitcoin Improv= ement Proposals (BIP)[1] process. Most work will be done outside of the wor= kshops 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, and accommodation rec= ommendation are available at scalingbitcoin.org. Registration begins August 12th at an early-bird ticket price of $150 = USD until September 3rd. The ticket prices do not come close to covering th= e venue expense and travel subsidies, hence the need for corporate sponsors= .

  • Plea= se see the FAQ at scalingbitcoin.org which s= hould answer most other questions.


T= ravel Subsidies for Independent/Academic Researchers

There will be an applicati= on process for independent or academic researchers to apply for travel assi= stance to help cover the expense of airfare and hotel fees up to $1,000 per= qualified presenter who intends to give a presentation.=C2=A0 The four und= erwriters of this event have agreed to jointly review applications and cove= r the travel subsidies for qualified presenters. See scalingbitcoin.org for details.


Sponsors of the Montreal Workshop

The first workshop is hosted and with logistics h= andled by the Montreal consultancy CryptoMechanics.


The Underwriters jointly responsible for venue ex= penses and researcher travel subsidies are currently the MIT Digital Curren= cy Initiative, Chaincode Labs, Blockstream, and Chain.com.

= Current sponsors include: Cryptsy, BitcoinTalk, Final Hash, Blockstream, MI= T DCI, Chaincode Labs, IDEO Futures, Kraken, and Chain.com.

Additional sponsors are needed. Please see scalingbitcoin.org for sponsorship details or contact me directly via < pindar d= ot wong at gmail.com >= ;
