Fresh off the launch of its first production-ready version Homestead, a number of bitcoin industry startups have begun to take a closer look at Ethereum, exploring its capabilities as part of pilot projects.Coming amid the ongoing block size debate, as well Coinbase CEO Brian Armstrong’s pointed criticisms of the bitcoin network, the event sparked speculation on social media forums in the days leading up to the event.However, while Coinbase co-founders Brian Armstrong and Fred Ehrsam were present at the event, there were no major announcements or indications that the startup was moving to formally embrace or begin building products on top of the technology.Comprising roughly 30 slides, Buterin's presentation gave an overview of Ethereum’s path forward, which will include two additional releases, dubbed Metropolis and Serenity, to be launched at later dates.Buterin discussed network statistics including the number of decentralized applications running on the platform, the price of its native token, ether, and the rising number of global meetups dedicated to Ethereum.

Still, Buterin sought to downplay expectations for the platform, indicating that, despite assertions, the toughest work for Ethereum's development team lies ahead.For example, Buterin said that ensuring optional privacy on the network and proving it can scale are current points of concern.Elsewhere, slides touched on the platform’s three-stage planned transition from proof of work to proof of stake transaction validation, and proposed improvements to its Ethereum virtual machines which handle the blockchain's internal state.The event was open to the public, and according to its Meetup page, drew roughly 40 attendees.Share Published on May 10, 2014 "The ethereum Experience" was a presentation by Dr Gavin Wood hosted at the ethereum London Meetup.Gavin presents an exclusive update in the latest developments of the ethereum platform, including some never-seen-before UI mockups of what ethereum might eventually look like at launch.Gavin also covers a more generalist view of ethereum and how it could fit in a zero-trust, decentralized 'Web 3.0' model as part of an ecosystem of decentralized content distribution, messaging and networking.
