• OnChain Scaling Conferences - 2016

    OnChain Scaling Conferences was a series of three, free, online conferences discussing issues surrounding scaling Bitcoin on-chain that we organised in 2016. A list of distinguished presenters shared their knowledge and ideas about the subject while approaching the problem from a technical, economic, legal or social angle. The events were set up to encourage the free flow of information on the subject and to encourage open and respectful discussion between developers, miners and other ecosystem stakeholders.

    We share some of our favourite presentation videos here.

    Amaury Séchet - A Journey to the Moon
    Bitcoin as a World Currency

    November 30th, 2016 Amaury Séchet presented his vision of how Bitcoin could in fact scale to become a world currency. Much of his comprehensive plan can today be seen in the Bitcoin Cash roadmap on BitcoinCash.org.
    This presentation was made shortly before he left Facebook to join the effort of returning Bitcoin to the goal of decentralised digital peer-to-peer cash for the world. After it became clear the goals were unlikely to be reached following the path of others, he created the Bitcoin ABC implementation with a more recent fork of the Bitcoin Core codebase. With others, he developed it to the full node software which lead the split between Bitcoin (BTC) and Bitcoin Cash (BCH) .

    Dr. Charles Evans - The Micro-Global Economy

    Associate Professor of Economics and Finance at Barry University in Miami, Florida, Dr, Charles Evans presented the compelling reasons for why Bitcoin is such an important innovation and technology and how it can help change the world. And how for this to become a reality the payment characteristics of Bitcoin need to be as frictionless as they were during the first 5 to 6 years.


    One of our favourite presentations and a reminder to all of the reasons for working as hard as we do at reaching the goals by making Bitcoin Cash success.

  • The Future of Bitcoin Conference

    July 30 and 31, 2017 - Arnhem, The Netherlands

    An international Bitcoin development conference focused on the subject of multiple implementations for Bitcoin, scaling Bitcoin on-chain and governance. Set in Bitcoin-city Arnhem, participants and attendees enjoyed being able to spend Bitcoin around the city. With the fees already having risen to uncomfortable heights it was very clear for attendees that something needed to change for this type of Bitcoin functionality to remain leasable. Three evenings and two days filled with presentations, discussions and people meeting face to face strengthened the belief that the clock was ticking and action was needed to return to the goals of economic freedom and financial sovereignty through decentralised digital peer-to-peer cash for the global population.

    Amaury Séchet - Back to Basics

    Presentation by Amaury Séchet on how Bitcoin can scale. Introduction to the Bitcoin ABC software that is to be used by Bitmain as a contingency plan during the activation of SegWit on the Bitcoin network.
    Shortly after this presentation took place Haipo Yang of ViaBTC announced the plan to mine using Bitcoin ABC software on August 1st 2017 and in doing so create a split in the Bitcoin network. ViaBTC exchange would also allow trading of the future tokens created by this split. The name and ticker and logo were not claimed by those moving to 8MB blocks, instead Haipo Yang announced the name would be Bitcoin Cash and the ticker BCC. This would be changed into BCH as the BCC logo was being claimed by another project. The logo was a bit later presented as the flag or bill shaped logo in the same colour orange that included the round Bitcoin logo but tilting it to the left instead of to the right.

    Antony Zegers - The Case for Market Governance of the Bitcoin Protocol

    Governance is still today a hot topic in cryptocurrencies and an ongoing discussion also within Bitcoin Cash. This thought provoking presentation is therefore still more than relevant and a must see for everybody interested in the inner workings of Bitcoin Cash.

    Jihan Wu - Why Bitcoin needs Multiple Implementations

    The keynote presentation by Bitmain co-founder and CEO Jihan Wu goes into the value of having multiple implementations, open source software project organisation and the social contract is broken by the development direction of Bitcoin (BTC) core development team. It gives some insight in why Bitmain and a large part of the Chinese mining community supported the SegWit2X movement but also the network split that took place one month after the conference and that created the Bitcoin Cash network.
