An Annual Event for the Bitcoin Community

  • Pier 35 San Francisco, CA United States (map)
  • Google Calendar ICS

From a white paper, some code and a simple message — “Chancellor on brink of second bailout for banks” — an idea was born that was so powerful it ignited a revolution. Captivated by Bitcoin's potential, individuals from around the world came together and formed a community to develop it.

After 10 years of bugs, hacks, scams, bans, civil war, breakthroughs and fortunes gained and lost, Bitcoin has spread like a virus around the world and has set the stage for a new financial system. Bitcoin's future has never been brighter, but much of the fun and positive spirit that got us here has been abstracted away. It's time for that to change. 

The mission of Bitcoin 2019 is to reignite the BTC community by advancing shared goals and highlighting the people and organizations bringing them into reality. From the biggest miners and most active core devs to Fortune 500 companies and darknet markets, this will be a yearly gathering of old and new friends that inclusively reimagines the narrative around digital value and manifests an amenable answer to the question: “Why does this technology matter?”

CryptoMondays: Whats so Stable about cryptocurrencies (Free)

A panel about stablecoins with Emre Tekisalp of Coinbase, Kory Hoang of Stably, Nik Kunkel of MakerDao, and more.

Event Details

Get your tickets now! Purchase below, this will sell out! (Sorry, no refunds)

All the power of a digital currency but with the stability of fiat, could stable coins be the answer to volatility or do they fundamentally not fit in crypto’s ethos? For years traders have leveraged the stability of stable coins to hold money on exchanges between trades. Fast forward just a few years later and large institutions like Coinbase, Gemeni, and JP Morgan are all throwing their coin into the proverbial fountain. And less obviously (yet so obviously) Facebook appears to have a toe in that fountain as well. Are things about to get a little unstable in the world of stable coins? Come listen to our panel of stable coin experts hash thru it and find out for yourself.


  • Emre Tekisalp from Coinbase

    • Emre Tekisalp leads business development for Coinbase's new businesses, including USDC and Coinbase Wallet. In his two years at Coinbase, he's also led various acquisitions, institutional partnerships and developer relations. Prior to Coinbase, Emre worked in product management and business development at Intel.

  • Kory Hoang from Stably Coin

    • Kory is the CEO & Co-Founder of Stably, a Seattle-based startup that recently listed their USDS token as the 5th fiat-backed stablecoin on Binance, the world's largest cryptocurrency exchange. Prior to founding Stably, Mr. Hoang was a Private Equity Data Analyst for PitchBook in Seattle. Mr. Hoang is also a quant who has consulted for money managers, hedge funds and CTAs on many subjects ranging from VIX derivatives to cryptocurrencies and algorithmic trading. Kory holds a BBA with double major in Finance and Marketing from the University of Washington - Bothell.

  • Nik Kunkel from MakerDao

    • Niklas has been involved in a broad spectrum of projects at MakerDAO, including proxies, decentralized exchanges, and market-making bots. Currently he's focused on building out Maker's next-gen decentralized Oracles for Multi-Collateral Dai.

  • Brandon Iles from Ampleforth

    • Brandon is a co-founder of Ampleforth. He spent over 5 years in Google's Search Ranking and Machine Intelligence groups and later worked in Uber's Location Search and Rider Prediction teams. He mined his first bitcoin so early he doesn't remember when it was and worked on one of the first mobile bitcoin wallets that were released onto the Android app store in 2011. He loves the intersection of Systems, Data, and Intelligence and holds a BS and MCS in Computer Science from Rice University.

Prism: Operating Blockchains At Physical Limits (Free)


Vivek Bagaria, a PhD student at Stanford, will be giving a talk about blockchain scalability.

We're very happy to have Vivek Bagaria [1] speaking on "Prism: Operating Blockchains At Physical Limits" [2]. Vivek is a PhD student at Stanford, working with David Tse [3] on machine learning, computational genomics, and statistics. We are always happy to hear new approaches solving to blockchain scalability, which is the first on Vitalik's list of "Problems" [4]. This is the first time I've seen a blockchain paper come from electrical engineering (information theory) academics; I'm looking forward to the talk! Vivek's abstract follows:

"Transaction throughput, confirmation latency and confirmation reliability are important performance measures of a blockchain protocol. These measures are limited by two underlying physical network attributes: communication capacity and speed-of-light propagation delay. Existing systems operate far away from these physical limits. In this work we introduce Prism, a new blockchain protocol, which can provably achieve 1) security against up to 50% adversarial hashing power; 2) optimal throughput up to the capacity C of the network; 3) confirmation latency for honest transactions proportional to the propagation delay D, with confirmation error probability exponentially small in the bandwidth-delay product CD ; 4) eventual total ordering of all transactions. Our approach to the design of this protocol is based on deconstructing the blockchain into its basic functionalities and systematically scaling up these functionalities to approach their physical limits."

We are very grateful to BNY Mellon Innovations [5] for hosting us and the Decentralization Foundation [6] for sponsoring. Please join us!

Socratic Seminar #10 (Free)

Discussion groups to discuss research and development of Bitcoin and related protocols.

Inspired by Bitdevs NY, this is an event for those interested in discussing and participating in the research and development of Bitcoin and related protocols. Unlike the monthly speaker event, the Socratic Seminar events are formatted to foster debate, information sharing and lively discussion.

Discussion topics from a variety of sources are collated by meetup members in the weeks preceding the events. We investigate pull requests in the Bitcoin Core, lnd, grin and other relevant repositories; we study network statistics, research papers, technical blog posts and other interesting content. To complete the meeting, members present open source projects, companies, research and other relevant materials. A feedback and Q&A section follow.

A newsletter is sent out the day of the event which outlines discussion topics. Archives of discussion topics and presentations can be found in the event descriptions of past meetups. The discussion portion of the event is NEVER recorded. It is recommended that you have a firm grasp of the basics of Bitcoin in order to extract the most value from our Socratic events.

Please contact the organizers if you'd like to present at a future Socratic event or have a recommended topic for discussion: leishman3 at gmail. There are different requirements for presentation depending on the type of project.

ECO Fashion Week SF presents : Blockchain for Sustainability


ECO Fashion Week | San Francisco presents : Blockchain for Sustainability

A newfound use case for blockchain proves that the technology could solve one of the world's most pressing issues: climate change. Blockchain is a term that people, from finance to food safety to supply chain operations, are encountering. . For this transformation towards sustainability Blockchain based applications could be an important enabling technology.

Blockchain offers the possibility to digitize and monitor clean energy production and consumption in a manner where more proactive decisions can be made, and more enduring and sustainable energy initiatives created. As a new digital age arrives, blockchain-based solutions oriented towards clean energy management stand to be automated through smart contracts, with additional decision making being done by artificially intelligent and “big-data” based machinery. In many ways, the tip of the iceberg is just being discovered.

In the fashion industry, that has seen major sweatshop scandals, consumers are becoming increasingly interested in ethical production. Organizations are now working with small textile producers to increase awareness around the value of what they produce, sharing the information as data on the blockchain with final consumers.

Hands-on Dapp creation with AmberData (Free)

We're happy to have Shawn Douglass and Joanes Espanol from Amberdata give an overview of their block explorer and other tools, including hands-on tutorials on building an Ethereum Dapp. Please bring your laptop so you can participate in the hands-on part of the event. We're also happy to have Danny Yang give a 5-minute demo of Blockseer [2], including their transaction graph visualization.

Amberdata's abstract: "Getting real-time Ethereum blockchain data and insights is hard. Now that tokens are traded across hundreds of crypto-exchanges, market insights and transparency have also become massively complex. The lifeblood of crypto economics, on-chain events, and transactions are inseparable from on-exchange economics. Amberdata incorporates on-chain and market data into a single API enabling institutional investors and value chain participants to build real-time data-powered applications."

"Amberdata will demonstrate their newly-released Data API, and walk thru hands-on tutorials building an Ethereum dapp, a lite wallet, and other applications."
