The Ripple ecosystem has many participants including gateways, market makers, and users—and we want to make it easier for you to customize the currencies and gateways that you access on Ripple Charts.

Although we have done our best to update the gateway list as often as possible, we are now launching a new feature that will allow you the ability to customize the currencies and gateways available in your Live Charts. The great news is that not only can you customize and add currencies and gateways to your hearts desire, you can also remove currencies and gateways that you never look at, enabling a more customized experience.

Customizing your currencies

Are you the type of person that might only look at 1 or 2 currencies on a regular basis? With the new dropdown customizations, you can now select the specific currencies that you would like to view.


1. Select on “Edit List” in the currency drop down.



2. You can also manage and deselect any currencies you aren’t interested in.



3. Return to the live chart to see your customized list!


Adding new currencies and gateways

Have you ever wanted to see Live Charts for a trading pair that wasn’t supported by the defaults provided by Ripple Charts? You can now add as many custom currencies and gateways as you choose.


1. Go back to the currency and gateway customization page and add your custom currency in the bottom field.



2. Once the currency is added, go to the “Manage Gateways” tab and select the custom currency you want to customize. Select or deselect any gateways that can be associated with the currency or add a custom gateway with the Ripple address or Ripple name.

Currency and gateway customization is only available on the ‘Live Chart’ page as of today. We plan to implement these customizations in the ‘Multi-Markets’ page within the next couple weeks.

Lastly, you’ll notice a slight facelift in the dropdowns as we’ve added new shiny logos for any gateways registered with the International Ripple Business Association (IRBA), a non-profit that sets standards and admits gateways based on their eligibility. Ripple Labs would like to promote best practices around compliance by featuring the logos of gateways that are members of IRBA and KYC their users. If you’re an IRBA member and not listed please contact our support team at . Also, please visit IRBA to become a member.

We hope these updates will provide benefit to those who’ve wanted some flexibility.

I was woken by Vitalik’s call at 5:55 this morning; pitch black outside, nighttime was still upon us. Nonetheless, it was time to leave and this week had best start on the right foot.

The 25-minute walk in darkness from the Zug-based headquarters to the train station was wet. Streetlights reflecting off the puddles on the clean Swiss streets provided a picturesque, if quiet, march into town. I couldn’t help but think the rain running down my face was a very liquid reminder of the impending seasonal change, and then, on consideration, how fast the last nine months had gone.

Solid Foundations

The last week was spent in Zug by the Ethereum foundation board and ÐΞV leadership: Vitalik, Mihai and Taylor who officially form the founation’s board, Anthony and Joseph as the other official advisors and Aeron & Jutta as the ÐΞV executive joined by Jeff and myself wearing multiple hats of ÐΞV and advisory). The chief outcome of this was the dissemination of Vitalik’s superb plan to reform the foundation and turn it into a professional entity. The board will be recruited from accomplished professionals with minimal conflicts of interest; the present set of “founders” officially retired from those positions and a professional executive recruited, the latter process lead by Joseph. Anthony will take a greater ambassadorial role for Ethereum in China and North America. Conversely, ÐΞV will function much more as a department of the Foundation’s executive rather than a largely independent entity. Finally, I presented the release strategy to the others; an event after which I’ve never seen quite so many photos taken of a whiteboard. Needless to say, all was well received by the board and advisors. More information will be coming soon.

As I write this, I’m sitting on a crowded early commuter train, Vinay Gupta in tow, who recently took on a much more substantive role this week as release coordinator. He’ll be helping with release strategy and to keep you informed of our release process. This week, which might rather dramatically be described as ‘pivotal’ in the release process, will see Jeff, Vitalk and me sit around a table and develop all the PoC-9 changes, related unit tests, and integrations in three days, joined by our indomitable Master of Testing, Christoph. The outcome of this week will inform our announcement which will come later this week outlining in clear terms what we will be releasing and when.

I’m sorry it has been so long without an update. The last 2 months has been somewhat busy, choked up with travel and meetings, with the remaining time soaked up by coding, team-leading and management. The team is now substantially formed; the formal security audit started four weeks ago; the bounty programme is running smoothly. The latter processes are the exceedingly capable hands of Jutta and Gustav. Aeron, meanwhile will be stepping down as the ÐΞV head of finance and operations and assuming the role he was initially brought aboard for, system modelling. We’ll hopefully be able to announce his successors next week (yes, that was plural; he has been doing the jobs of 2.5 people over the last few months).

We are also in the process of forming partnerships with third parties in the industry; George, Jutta and myself managing this process; I’m happy to announce that at least three exchanges will be supporting Ether from day one on their trading platforms (details of which we’ll annouce soon), with more exchanges to follow. Marek and Alex are providing technical supprt there with Marek going so far as to make a substantial reference exchange implementation.

I also finished the first draft of ICAP, the Ethereum Inter-exchange Client Address Protocol, an IBAN-compatible system for referencing and transacting to client accounts aimed to streamline the process of transfering funds, worry-free between exchanges and, ultimately, make KYC and AML pains a thing of the past. The IBAN compatibility may even provide possibility of easy integration with existing banking infrastructure in some future.


Proof-of-Concept releases VII and VIII were released. NatSpec, “natural language specification format” and the basis of our transaction security was prototyped and integrated. Under Marek’s watch, now helped by Fabian, ethereum.js is truly coming of age with a near source-level compatibility with Solidity on contract interaction and support for the typed ABI with calling and events, the latter providing hassle-free state-change reporting. Mix, our IDE, underwent its first release and after some teethng issues is getting good use thanks to the excellent work done by Arkadiy and Yann. Solidity had numerous features added and is swiftly approaching 1.0 status with Christian, Lefteris and Liana to thank. Marian’s work goes ever forward on the network monitoring system while Sven and Heiko have been working diligently on the stress testing infrastructure which analyses and tests the peer network formation and performance. They’ll soon be joined by Alex and Lefteris to accellerate this programme.

So one of the major things that needed sorting for the next release is the proof-of-work algorithm that we’ll use. This had a number of requirements, two of which were actually pulling in opposite directions, but basically it had to be light-client-friendly algorithm whose speed-of-mining is proportional to the IO-bandwidth and which requires a considerable amount of RAM to do so. There was a vague consensus that we (well.. Vitalik and Matthew) head in the direction of a Hasimoto-like algorithm (a proof-of-work designed for the Bitcoin blockchain that aims to be IO-bound, meaning, roughly, that to make it go any faster, you’d need to add more memory rather than just sponsoring a smaller/faster ASIC). Since our blockchain has a number of important differences with the Bitcoin blockchain (mainly in transaction density), stemming from the extremely short 12s block time we’re aiming for, we would have to use not the blockchain data itself like Hashimoto but rather an artifcially created dataset, done with an algorithm known as Dagger (yes, some will remember it as Vitalik’s first and flawed attempt at a memory-hard proof-of-work).

While this looked like a good direction to be going in, a swift audit of Vitalik and Matt’s initial algorithm by Tim Hughes (ex-Director of Technology at Frontier Developments and expert in low-level CPU and GPU operation and optimisation) showed major flaws. With his help, they were able to work together to devise a substantially more watertight algorithm that, we are confident to say, should make the job of developing an FPGA/ASIC sufficiently difficult, especially given our determination to switch to a proof-of-stake system within the next 6-12 months.

Last, but not least, the new website was launched. Kudos to Ian and Konstantin for mucking down and getting it done. Next stop will be the developer site, which will be loosely based on the excellent resource at, the aim to provide a one-stop extravaganza of up to date reference documentation, curated tutorials, examples, recipes, downloads, issue tracking, and build status.


So, as Alex, our networking maestro might say, these are exciting times. When deep in nitty gritty of development you sometimes forget quite how world-altering the technology you’re creating is, which is probably just as well since the gravity of the matter at hand would be continually distracting. Nonetheless, when one starts considering the near-term alterations that we can really bring one realises that the wave of change is at once unavoidable and heading straight for you. For what it’s worth, I find an excellent accompaniment to this crazy life is the superb music of Pretty Lights.

The post Gav’s Ethereum ÐΞV Update V appeared first on .


First of all, happy new year! What a year it has been. With a little luck we’ll surpass last year with an even more awesome year. It’s been too long since I’ve given an update on my side of things and that of the Go team and mostly due to a lack of time. I’ve been so incredibly busy and so many things have happened these past 2 months I’ve hardly had time to sit down and assess it all.

As you may be well aware the audit is looming around the corner and my little baby (go-ethereum!) will undergo it’s full inspection very, very soon. The audit teams will tear it apart and see if the repo contains anything incorrectly implemented as well as search for any major security flaws in the design and implementation. We’ve been pretty solid on tests, testing implementation details as well as consensus tests (thanks to Christoph) and will continue to add more tests over time. We’ll see how they hold up during the audit (though I’m confident we’ll be fine, it’s still a little bit scary (-:)


PoC-7 has been released now for a about a week and has been quite stable (and growing in size!). We’re already hard at work to finalising PoC-8 which includes numerous small changes:

  • Adjusted block time back to 12s (was 4s)
  • Op code PREVHASH has become BLOCKHASH( N ) and therefore PREVHASH = BLOCKHASH(NUMBER - 1)
  • We’ve added an additional pre-compiled contract at address 0x04 which returns the given input (acts like copy / memcpy)



Felix has been hard at work on our new P2P package which has now entered in to v0.1 (PoC-7) and will soon already undergo it’s first upgrade for PoC-8. Felix has done an amazing job on the design of the package and it’s a real pleasure to work with. Auto-generated documentation can be found at GoDoc.


A month or so back I finished the first draft of Whisper for the Go implementation and it’s now passing whisper messages nicely around the network and uses the P2P package mentioned earlier. The Go API is relatively easy and requires almost zero setup.


The backend stack of ethereum has also received its first major (well deserved) overhaul. Viktor’s been incredibly hard at work to reimplement the download manager and the ethereum sub protocol.


Since the first day Dani joined the team he’s passionately been working on the peer selection algorithm and distributed preimage archive. The DPA will be used for our Swarm tech. The spec is about 95% complete and roughly about 50% has been implemented. Progress is going strong!

Both go-ethereum/p2p and go-ethereum/whisper have been developed in such a way that neither require ethereum to operate. If you’re developing in Go and your application requires a P2P network or (dark) messaging try out the packages. An example sub protocol can be found here and an example on how to use Whisper can be found here.

Ams Hub

Now that the hub is finally set up you’re free to drop by and grab a coffee with us. You can find us in the rather posh neighbourhood of Amsterdam Zuid near Museumplein (Alexander Boerstraat 21).

In my next post I hope I’ll have a release candidate for PoC-8 and perhaps even a draft implementation of swarm. But until then, happy whispering and mining!

The post Jeff’s Ethereum ÐΞV Update II appeared first on ethereum blog.

Beim Ethereum IPO ist wieder einmal Sand im Getriebe. Das Fundraising wurde gestoppt, also man kann nicht investieren ab dem 1. Februar. Es wurde auf einen unbestimmten Zeitpunkt nach hinten verschoben.
ethereum – Google Blogsuche

Time for another update! So quite a bit has happened following ÐΞVcon-0, our internal developer’s conference. The conference itself was a great time to get all the developers together and really get to know each other, dissipate a lot of information (back to back presentations for 5 days!) and chat over a lot of ideas. The comms team will be releasing each of the presentations as fast as Ian can get them nicely polished.

During the time since the last update, much has happened including, finally, the release of the Ethereum ÐΞV website, Though relatively simple as present, there are great plans to extend this into a developer’s portal in which you’ll be able to browse the bug bounty programme, look at and, ultimately follow tutorials, look up documentation, find the latest binaries for each platform and see the progress of builds.

As usual I have been mostly between Switzerland, the UK and Berlin, during this time. Now that ÐΞV-Berlin is settled in the hub, we have a great collaboration space in which volunteers can work, collaborate, bond and socialise alongside our more formal hires. Of late, I have been working to finish up the formal specification of Ethereum, the Yellow Paper, and make it up to date with the latest protocol changes in order that the security audit get underway. Together we have been putting the finishing touches on seventh, and likely final, proof-of-concept code, delayed largely due to a desire to make it the final PoC release for protocol changes. I’ve also been doing some nice core refactoring and documentation, specifically removing two long standing dislikes of mine, the State::create and State::call methods and making the State class nicer for creating custom states useful when developing contracts. You can expect to see the fruits of this work in Milestone II of Mix, Ethereum’s official IDE.

Ongoing Recruitment

On that note, I’m happy to announce that we have hired Arkadiy Paronyan, a talented developer originally from Russia who will be working with Yann on the Mix IDE. He’s got off to a great start on his first week helping on the front-end with the second milestone. I’m also very pleased to announce that we hired Gustav Simonsson. Being an expert Erlang with Go experience with considerable expertise in network programming and security reviewing, he will initially be working with Jutta on the Go code base security audit before joining the Go team.

We also have another two recruits: Dimitri Khoklov and Jason Colby. I first met Jason in the fateful week back last January when the early Ethereum collaborators got together for a week before the North American Bitcoin conference where Vitalik gave the first public talk about Ethereum. Jason, who has moved to Berlin from his home in New Hampshire, is mostly working alongside Aeron and Christian to help to look after the hub and looking after various bits of administration that need to be done. Dimitri, who works from Tver in Russia is helping flesh out our unit tests with Christoph, ultimately aiming towards full code coverage.

We have several more recruits that I’d love to mention but can’t announce quite yet – watch this space… (:

Ongoing Projects

I’m happy to say that after a busy weekend, Marek, Caktux, Nick and Sven have managed to get the Build Bot, our CI system, building on all three platforms cleanly again. A special shout goes out to Marek who tirelessly fought with CMake and MSVC to bend the Windows platform to his will. Well done to all involved.

Christian continues to power through on the Solidity project, aided now by Lefteris who focuses more on the documentation side. The latest feature to be added allows for the creation of new contracts in a beautiful manner with the new keyword. Alex and Sven are beginning to work on the project of introducing network well-formedness into the p2p subsystem using the salient parts of the well-proven Kademlia DHT design. We should begin seeing some of this stuff in the code base within before the year-end.

I’m also happy to announce that the first successful message was sent between Go & C++ clients on our messaging/hash-table hybrid system, codenamed Whisper. Though only at an early proof-of-concept stage, the API is reasonably robust and fixed, so largely ready to prototype applications on.

New Projects

Marian is the lucky guy who has been tasked with developing out what will be our awesome web-based C&C deck. This will provide a public website whose back-end connects to a bunch of nodes around the world and displays real-time information on network status including chain length and a chain-fork early warning system. Though accessible by anyone, we will of course have a dedicated monitor on at all times for this page at the hub.

Sven, Jutta and Heiko have also begun a most interesting and important project: the Ethereum stress-testing project. Designed to study and test the network in a range of real-life adverse situations prior to release, they will construct infrastructure allowing the setup of many (10s, 100s, even 1000s of) nodes each individually remote-controllable and able to simulate circumstances such as ISP attacks, net splits, rogue clients, arrival and departure of large amounts of hash-power and measure attributes like block & transaction propagation times and patterns, uncle rates and fork lengths. A project to watch out for.


The next time I write this I hope to have released PoC-7 and be on the way to the alpha release (not to mention have the Yellow Paper out). I expect Jeff will be doing an update concerning the Go side of things soon enough. Until then, watch out for the PoC-7 release and mine some testnet Ether!

Bei Ethereum gibt es neue Informationen zum IPO. Chefentwickler Vitalik Buterin hat die geänderten IPO-Bedingungen im Bitcointalk veröffentlicht. Überraschend war zunächst einmal die Preiserhöhung für mich. So erhält …
ethereum – Google Blogsuche

I’m Gavin Wood, a co-founder of Ethereum and, along with Vitalik Buterin and Jeffrey Wilcke, one of the three directors of the Eth Dev, the NFP organisation that is managing the development (under contract from Ethereum Suisse) of the Ethereum blockchain. This is a small update to let you all know what has been going on recently.

I sit here on an immaculate couch that has been zapped forward in time from the 1960s. It is in the room that will become the chillout & wind-down room of the heart of the (C++) Ethereum development operation. Surrounding me is Alex Leverington on a Bond villain’s easy chair, and Aeron Buchanan stuck behind a locker that looks as though it was an original prop from M*A*S*H. Lighting equipment from a Soviet Blade Runner, now forgotten except in Berlin’s coolest districts where renaissance chemistry and 60s luxury breath Frankensteinesque life into it, provides an unyielding glow to the work in progress. There is still much to be done here (I feel a little like I’m on the set of Challenge Anneka) but it is undeniably taking shape. This is thanks mostly to our own Anneka Rice, Sarah O’Neill, who is working around the clock to get this place ready for ÐΞVcon-0, our first developer symposium. Helping her, similarly around the clock, is the inimitable Roland, a hardened international interior outfitter whose memoirs I can’t wait to read.

On a personal note, I must say these last few months have been some of the busiest of my life. I spent the last couple of weeks between Switzerland and the UK, visiting Stephan, Ian and Louis. Despite the draws of the north of England, it’s nice to be back in Berlin; the combination of great burgers and cocktails, beautiful surroundings and nice people makes it difficult to leave. Awesome C++ coders are welcome to take that as a hint: we’re still hiring (-:


During the last couple of weeks we’ve made a number of important revisions to the protocol, mostly provisions for creating light-client ÐApp nodes. There will be a directors’ post in due course detailing these, but suffice it to say we are as committed as ever that the Ethereum blockchain make possible the massively multi-user decentralised applications for all sizes of devices. The seventh in our proof-of-concept series is awaiting imminent release and the final in the series, PoC-8 will be starting development shortly.

Fresh meat

As time goes on, our team moves from strength to strength. I’m pleased to announce that Dr. Sven Ehlert has joined us. He will be leading development operations; cleaning up the build process, making the build as robust as possible, assisting Caktux in our CI systems and, most importantly, helping architect a stress-testing harness in which we’ll be simulating a series of extreme situations, measuring and analysing. He’s also a scrum aficionado and will be helping us streamline some of our development processes as our team grows.

It is with great pleasure I can also announce that Dr. Jutta Steiner will also be working closely with us in the capacity of managing our security audit. As well as being an enthusiastic ÐApp-developer, she comes with an excellent track record of handling projects and a superb understanding of not only this cutting edge technology but also the human processes that must go on behind it.

I must also shout out to Dr. Andreas Lubbe; though a long-time member of the Berlin Ethereum community and having worked on Ethereum-related code (a notable devotee of node.js), we have recently started working much more closely together on the secure Ethereum contract documentation (SECDoc) framework and the associated natural language specification format, NatSpec. I look forward to some great collaboration.

Aside from Lefteris, who began his first official day with us today (working with Christian on Solidity, and more specifically on the SECDoc and NatSpec portions of it), we have two new developers joining us: Yann Levreau and Arkadiy Paronyan. Yann, a recent arrival in Berlin from his native France will be joined by Arkadiy who is travelling all the way from Moscow to become part of the team. Both have substantial experience in C++ and related technologies and will be helping us flesh out the developer tools and in particular pave the way to the IDE vision.

Finally, I’m happy to report that Christoph Jentzsch, though originally joining us for only 2 months (while taking time out from his doctoral studies), will be joining the project full time in the new year and continuing his much appreciated work on our tests and the general C++ health and robustness.


As time rushes by, Sarah, Roland and their team rush even more to finish our hub. For they know that come Monday the 24th, Berlin will have some new arrivals. Developers and collaborators from around the globe will descend on 37a Waldemarstraße, Berlin 10999 for a week of getting everybody on the same page. It is DEVcon-0: ethereum’s first developer symposium.

Conceived by myself and Jeff on a sleepy train from Zug to Zurich as a means of getting the Amsterdam/Go guys on the same page as the Berlin/C++ guys it has evolved into a showcase, set of seminars and workshops of all of ÐΞV, our technologies, our personnel and some of our close collaborators. It is a chance for us each to build lasting professional relationships and bond in what will become a project that may if not define, certainly form a hallmark, on our professional lifes.

Our hub will play host to around 40 people, the vast majority of which are accomplished technical minds that Jeff, myself or Vitalik has at one point or another mentioned, and for the period of a week we will be chatting, mingling and sharing our ideas, hopes and dreams for everything blockchain, decentralised and disruption related. It’s going to be awesome: look out for the videos!

Ever closer

Aside from the continuing work towards starting PoC-8 and the alpha series, I’m glad to report that the Solidity project storms onwards under the stewardship of Christian: the first contracts compiled with Solidity have been delivered and tested working on the testnet, and as I write this I see another Pull Request for state mappings. Great stuff.

Alex has also been working tirelessly on our crypto code and is now beginning work on the p2p layer, the full strategy for which we’ll be seeing in his address at ÐΞVcon. Marek and Marian have also been busy on the Javascript API, and I can assure any Javascript ÐApp developers that they will have a lot to look forward to in PoC-8.

Summing Up

There are also a few other developments and personnel I’d love to announce, but I fear, once again, it will have to wait until next time. Watch this space for a post-ÐΞVcon update!


The post Gav’s Ethereum ÐΞV Update III appeared first on ethereum blog.

ethereum blog

Hi, I’m Stephan Tual, and I’ve been responsible for Ethereum’s adoption and education since January as CCO. I’m also leading our UK ÐΞV hub, located at Co-Work in Putney (South West London).

I feel really privileged to be able to lead the effort on the communication strategy at ÐΞV. For the very first time, we’re seeing the mainstream public take a genuine interest in the potential of decentralisation. The feeling of excitement about what ‘could be’ when I first read Vitalik’s whitepaper on that fateful Christmas afternoon is now shared by dozens of thousands of technologists, developers and entrepreneurs.

Thanks to the Ether sale, a group of smart, hardworking individuals is now able to work full time on solving core technical and adoption challenges, and to deliver a solution at 10x the speed an equivalent garage-based initiative would have taken. With Ethereums’ APIs supporting Gav’s vision for web 3, it finally is in the reach of the community to build decentralized applications without middlemen. By democratizing access to programmable blockchain technology, Ethereum empowers software developers and entrepreneurs to make a major impact on not only the decentralisation of the economy, but also social structures, voting mechanisms and so much more. It’s a very ambitious project, and everyone at ÐΞV feels a strong sense of duty to to deliver on this vision.

As part of our efforts, technology is – of course – key, but so is adoption. Ethereum without dapps (decentralized apps) would be akin to a video game console without launch titles, and, just like any protocol, we expect the applications to be the real stars of the show. Here’s how we plan to spread the word and support developers in their efforts.


Building a curriculum: We’re building an extensive curriculum adapted to both teachers and self-learners at home, at hackathons and in universities around the globe. Consisting of well defined modules progressing over time in their complexity, our goal is to establish a learning standard that will be of course completely free of charge and 100% Open Source.

Content aggregation: at the moment we are aware that information on how to ‘get into’ Ethereum is a little bit fragmented between forums, multiple wikis and various 3rd party sites. A subdomain to our website will be created during the course of the next few months to access this valuable information easily and in one place.

Produce tutorials, videos and articles: tutorials are key to learn a new set of languages and tools. By producing both videos and text-based tutorials, we intend to give the community an insiders’s view on best practices, from structuring contract storage to leveraging the new whisper P2P messaging system for example.

CodeAcademy-like site: not everyone likes to learn within a classroom environment, and some feel constrained by linear tutorials. With a release date coinciding with the launch of Ethereum, we’re partnering with a US-based company to build a CodeAcademy-like site within a gamified environment, where you’ll be able to learn at your own pace how to build dapps and their backend contracts.

University chapters: Vitalik and I recently gave a presentation at Cambridge University and Ethereum will participate in the Hackathon on Transparency on November 26 at the University of Geneva. Encouraged by the enthusiasm we’ve witnessed in the academic world, we are working to support directly the Oxbridge Blocktech Network (OBN) in their efforts to build a network of chapters, firstly within the UK then throughout Europe.

I’m happy to announce that Ken Kappler has joined the UK team to help with these educational efforts. Many of you in London know Ken as he’s been a semi-permanent fixture at all our meetups and hackathons, kindly helping behind the scenes. Ken, known as BlueChain on IRC, is also the writer behind which will soon merge with our own education site.

Ken will lead a weekly ‘Ethereum Clinic’ on IRC to answer any questions you might have with your current project. Times will be posted on our forums.


Encouraging the creation of new meetups: we now have an extensive network of 85 meetups worldwide, which is an amazing achievement but not sufficient to handle the overwhelming demand for regular catchups in a format that’s appropriate for the local needs and culture. We intend to encourage the creation of new meetups in almost every country and major urban hubs.

Tooling and support: in order to drive the effort to create and maintain such a large network of international meetups, we will be providing tools for meetup leaders to interact with each other, gain access to the core dev team for video-conference or physical interventions, and exchange information about speakers. These tools will of course be free to use and access.

Collaterals and venues: for the meetups that are the most active, Ethereum is considering, where appropriate, the use of small bursaries so that meetup leaders in these ‘core locales’ do not have to contend with the full costs of collaterals and venues. We will also work with our partners to help meetups secure sponsorships and access to free locations to hold their mini-conferences.

Global Hackathon: Starting this week, the Ethereum workshops are going to slowly transform into proper hackathons. We are working with wonderful locations around the globe, the vast majority of which started off as Ethereum meetups, to organize a worldwide hackathon with some great ETH prizes for the best dapps.

We’re very lucky to welcome Anthony D’onofrio to drive these very important initiatives. Anthony starts on the 10th of this month and will also cover the North American region from a community perspective – you probably already know him as ‘Texture’, his handle on most forums and channels.


I’m incredibly proud that Ethereum’s exposure in the community has been entirely organic since day one. This has been the result of major, time consuming efforts to identify Ethereum projects in the wild, reaching out directly and building a strong relationship with our user base. We have achieved several key milestones, including over 10,000 followers on Twitter, 100,000 page views per month on our website, similar numbers on our forums and the growth trend only continues to accelerate.

Historically, Ethereum has never used PR as a tool to increase adoption, relying instead on word of mouth, meetups and conferences to spread the word. As the media attention is now intensifying rapidly, I’m pleased to welcome Freya Stevens to the team as PR/Marketing lead. Freya will help us build a shared database of media leads, write articles and make complex technology palatable to the general public while identifying strong story angles. Freya is based out of Cambridge, UK.

Also with a view to to scale up these initiatives we’re proud to welcome George Hallam to the team, AKA thehighfiveghost, who recently posted a survey so you can let Ethereum know how well we’re doing our job as custodians and developers of the platform. George, as a key supporter to the London community, will be already be familiar to many.

As part of these efforts, expect to see a lot more interactions on Reddit, IRC, Discuss and of course our very own forums. George will also help me identify key Ethereum-based projects and make contact to see how we can best help with information, connections and inclusion as guests in our weekly video updates, shot at our Putney Studio.

In order to produce very high quality content, we are also welcoming Ian Meikle to the London Hub. Ian is the creator of most of the video materials you might have seen relating to Ethereum, including the superb video loop that has been a staple at many Ethereum meetups. Ian will leverage the equipment at our studio to create explainer videos, interview key players in the space, and record panels led by Vinay Gupta, who joins the coms team as Strategic Consultant.

In London, and above and beyond our existing panels, socials and hackathons, regular ‘show and tell’ are being scheduled for dapp developers to present their work and receive feedback, a model we intend to promote internationally within the month.

And of course, last but not least, expect a major refresh to our website, with beautiful, clean content, practical examples of dapps, a dynamic meetup map and links to all our newly created assets and community points of contacts.

In conclusion

The question we’re going to continue asking ourselves everyday is how do we support you, the community, in building kick-ass dapps and being successful in your venture on our platform. I hope the above gives you a quick intro as to our plans. I’ll be issuing regular updates both on this blog and on our youtube.

The post Ethereum Community and Adoption Update – Week 1 appeared first on ethereum blog.

ethereum blog

I thought it was about time I’d give an update on my side of things for those interested in knowing how we’re doing on the Dutch side. My name is Jeff, a founder of Ethereum and one of the three directors (alongside Vitalik and Gavin) of Ethereum ÐΞV, the development entity building Ethereum and all the associated tech.

Over the past months I’ve been been looking for a suitable office space to host the Amsterdam Hub. Unfortunately it takes more work than I initially anticipated and have got nothing to show for so far. I’ve past on this tasks to my good friend and now colleague Maran. Maran will do all he can to find the best suitable place for the Ams hub and the development of Mist. Those who are using the Ethereum Programming language mutan you may want to switch over to Serpent or the soon to be de-facto programming language Solidity. I’ve made the sensible decision to focus my attention on to more pressing matters such as the development of the protocol and the browser. Perhaps in the future I’ll have time to pick up it’s development again.

ÐΞV Amsterdam

The lawyers have finally, after 2 months, gotten around to set up the company here in Amsterdam (ugh, the Dutch and their bureaucracy eh) and we’ve found a bank that is willing to accept us as their loyal customers (…). At the moment we have a few options for our office space and I’ll write about them as soon as I know something more concrete.

The Team

It’s about time the Ams team got a proper introduction. These guys do some serious good work!

The first that joined the Ams team is Alex van de Sande (aka avsa). Alex is a gifted UX engineer and he’s been with us for quite a while. It was only a matter of time before he became an official member of the ÐΞV team. Alex has taken up the task of UI development and UX expert and is prototyping the latest of the Web3 browser.

The second that joined the team is Viktor Trón. Vik is a crazy math-head and is currently hacking away at the new DEVP2P and testing it rigourously. I’ve known Vik all the way back since the start of the project somewhere in Jan/Feb, he’s a great guy and a real asset to this team.

The third that joined the team is Felix Lange. Felix is a die-hard Gopher (yay!) and the first thing he pointed out to me was that I had done a bad job looking after my go routines and there were a lot of race conditions, so nice of him (-; Felix is going to work on the Whisper implementation once the spec has been formally finalised. Felix is a super star gopher and has the ability to become a true Ethereum Core Dev.

The fourth that joined the team is Daniel Nagy. Daniel has a history in crypto and security and his first tasks is to create a comprehensive spec for our DHT implementation and the development thereof.

Last but certainly not least is Maran Hidskes. Maran has been on this team before but in a completely different role. Maran used to work on the protocol but after spawning a crying, -peeing, -pooping machine new member of his family he decided to take some time off. Now his main role is to look after the daunting task; the administration of ÐΞV Amsterdam.

Even though they are not on anyone’s team, I like to thank Nick, Caktux and Joris for their ongoing effort in developing out our build systems. I’d also like to thank Nick specifically for pointing out the inconsistencies between our implementations: Nick, you truly are a great pain in my ass (-;


While we are marching towards the next instalment in the Proof of Concept (PoC-7) we still have got quite some work ahead of us.

Recently I’ve started to build a toolset so we may test out Christoph (he’s on the Berlin team) awesome tests suit. Christoph has put a tremendous amount of work in developing out a proper testing suit for the Ethereum protocol. I never knew people could enjoy writing tests like you do, you’ve got my uttermost most respect.

I’ve also started a cross-implementation JavaScript framework called ethereum.js. Ethereum.js is quickly gaining adoption from the rest of the Ether Hackers and is already in use by the Go websocket & JSON RPC implementation, C++ JSON RPC implementation and the Node.js implementation. Ethereum.js is a true ÐΞV cross implementation team effort.

Our Polish partners at IMAPP (Paweł and Artur) have completed their first implementation of the JIT-compiled LLVM-based EVM implementation and have agreed to create a Go bridge so that Mist may benefit from the speed increase in running Ethereum contracts mentioned earlier in Gav’s update.

Finally, the UX and UI refinement of Mist, our flagship consumer product and next-generation browser, continues at great pace. An early ‘preview’ of the Mist interface can be downloaded here. It’s going to be impossible to deliver that type of behemoth of a browser for the first version but it will certainly be the end-goal.


I shall try to keep up writing blog post with updates regarding Mist, the protocol and ÐΞV in general so stay tuned!

The post Jeff’s Ethereum ÐΞV Update I appeared first on ethereum blog.

Well… what a busy two weeks. I thought it about time to make another update for any of you who might be interested in how we’re doing. If you don’t already know, I’m Gavin, a founder of Ethereum and one of the three directors (alongside Vitalik and Jeffrey) of Ethereum ÐΞV, the development entity building Ethereum and all the associated technology.

After doing some recruitment on behalf of DEV in Bucharest with the help of Mihai Alisie and the lovely Roxanna Sureanu I spent the last week at my home (and coincidentally, the Ethereum HQ) in Zug, Switzerland. During this time I was able to get going on the first prototype of Whisper, our secure identity-based communications protocol, finishing with a small IRC-like ÐApp demonstrating how easy it is to use. For those interested, there is more information on Whisper in the Ethereum Github wiki and a nice little screenshot on my twitter feed. In addition to this I’ve been helping finalise the soon-to-be-announced PoC-7 specification and working towards a PoC-8 (final). Finally, during our brief time together in Zug, Jeffrey, Vitalik and I drafted our strategy concerning identity and key management; this will be developed further during the coming weeks.


In Berlin, Sarah has been super-busy with the builders getting the hub ready. Here’s a couple pictures of the work in progress that is the Berlin hub. It might not look like much yet, but we’re on target to be moved in by mid-November. I’m particularly happy with Sarah’s efforts to find a genuine 70′s barrista espresso machine (-:

I’m excited to announce that Christian Vömel is joining the team in Berlin to be the Office Manager of ÐΞVHUB Berlin. Christian has many years experience including having worked in an international environment and has even taught office management! He’ll be taking some of the load from our frankly much-overworked company secretary Aeron Buchanan.

The Team Grows

We’ve finalised a number of new hires over the past couple of weeks: Network engineer Lefteris Karapetsas will be joining the Berlin team imminently. Having considerable experience with state-of-the-art network traffic analysis and deep-packet inspection systems, he’ll be helping audit our network protocols, however (like much of our team) truly multidisciplinary, he’ll also be working on NatSpec, the code name for our Natural Language Formal Contract Specification system, a cornerstone of our transaction security model.

I’m happy to announce that Ian Meikle, the accomplished videographer who co-authored the impressive “Koyaanis-glitchy” Ethereum brand video has been moved to ÐΞV to help with the communications team. He who shall be known only as Texture has also joined the comms side with Stephan to help with the strategy stateside and coordinate the worldwide meetup and hackathon network. Great to see such a capable and passionate designer on the team; I know he has a good few ideas for ÐApps!

Two more hires under Stephan in the comms team include Ken Kappler, handling the developer education direction, hackathons, ethereum curriculum and university partnerships. George Hallam has also been employed to evangelize ethereum to startups and partners, boost the reach of our formal network and generally help Stephan in the quest of having everybody know what Ethereum is and how it can help them.

Jeff’s team has also been expanded recently too; he’ll be telling you about his developments in an imminent post.

Further Developments

Aside from the aforementioned progress with Whisper and PoC-7, Christoph has been continuing his great work with the tests repository. Christian has been making great progress with the Solidity language having recently placed the first Solidity-compiled program onto the testnet block chain only a few days ago.

Marek has studiously been moving C++ over to a JSON-RPC and Javascript front-end fundamentally unified and bound to the Go client. Alex meanwhile has been grappling with the C++ crypto back-end and has done a great job of reducing bloat and extraneous dependencies.

Of late, the comms team has some good news brewing, in particular, it is in contact with some world-class education establishments regarding the possibility of eduction partnership and the formation of a network of chapters both in the UK and internationally. Watch this space (-:

Finally, our Polish partners at IMAPP (Paweł and Artur) have completed their first implementation of the JIT-compiled LLVM-based EVM implementation. They are reporting an average of 30x speedup (as high as 100x!) for non-external EVM instructions over the already best-in-class basic C++-based EVM implementation. Brilliant work and we’re looking forward to more improvements and optimisations yet.

And the rest…

So much to come; there are a couple of announcements (including a slew of imminent hires) I’d love to make but they need to be finalised before I can write about them here. Look out for the next update!
