It was humbling to see how Ethereum has attracted such a magnificent team of incredibly talented people from such a wide variety of backgrounds. Next up, Stephan Tual gave a talk highlighting the important role of the UK based communications team in building a strong and populous Ethereum community.
Still, there is always more to be done. With the inclusion of 4 new members to the team, new educational tools on the horizon and increased interaction with the community, Stephan hopes Ethereum can become a worldwide phenomenon as we move forward to the release of the genesis block. This will hopefully increase the overall output whilst breaking down what is a truly enormous project into manageable pieces.
You can try solidity in your browser now. The concept is to intertwine documentation and code in Solidity so that the documentation can be used by the client to alert the user of any significant actions that may take place as a consequence of running the code in certain smart contracts. Marek Kotewicz then gave an update on the Javascript API in a workshop setting allowing a lot of to-and-fro with the audience. He explained how it works, how to use it with smart contracts and what tools will be available to enable its use and uptake in the future.
Participants of the network share their computing power and in return receive a token of worth, incentivising their continued participation. Users can also access the resources to implement their own tasks and distribute them across the network. CI is a concept intended to improve the quality of whichever project it is being used with. Though Ethereum already uses CI, we wish to further refine the process as we move forward. To this end, Sven introduced several new and different implementations to make the developers lives easier as the project moves forward.
With Martin Becze arriving from San Francisco, we had representatives for each client ready for a panel talk later on in the day. Each person had a chance to stand up and offer their own personal 30 second definition on what Ethereum is. The answers were diverse, and it was interesting to see how people changed their angle of approach depending on which audience the explanation was aimed at. Jeff Wilcke also gave a brief update on Ethereum Go client on the whiteboard before the panel discussion.
Each took turns outlining how each client handles state transactions, moves account balances, runs the EVM and saves data to accounts whilst handling sucides and out-of-gas exceptions. Questions where then posed by the audience, discussions continued on late into the night as day 3 drew to a close. Day 4 — Thursday 27th Nov — Robustness and security. To this end, the Ethereum team is working very hard to audit the software with several external partners and ensure network stability from the release of the genesis block onwards.
The goal of the project is to again use continuous integration and take it one step further. With CI, the Dev team can test to make sure that each client will behave correctly when it executes a contract.
In this respect it will simulate how clients would interact with the blockchain in the real world. This will allow us to understand how the network will behave if the clients have different properties. For instance — clients with low bandwidth and less cpu power interacting with those with more resources available. The project pays special attention to how this will affect potential forks of the blockchain. Later on, the team will simulate attacks on the Ethereum blockchain and network to test its durability and resilience.
After the workshop, Christoph Jenzsch presented on the why and how of unit testing in the Ethereum project. In his talk, Christoph described several different types of test that need to be carried out — unit tests, integration tests and system tests.
She explained how our approach to security is to initiate both an internal audit and a massive external audit with established software security firms, academics, blockchain research firms and companies interested in utilising Ethereum all taking part. Jutta is also working on a bounty program which will be open to the community rewarding those who test and explore the protocol and software.
The p2p networking protocol is geared towards security as it is entirely encrypted from end to end. He contrasted the Ethereum network with the internet as we know it today, emphasising the difference between using SSL certificates and p2p anonymous networks. Gavin followed up with a presentation on the what and why of Whisper: Consensus is expensive, and for things like pure communications there are more elegant solutions available than using blockchain tech, hence the need for Whisper.
This will allow peers to connect to other peers distributed throughout the network instead of peer that are simply close to each other. By deterministically connecting to random peers, you know that each peer will have a better picture of the overall state of the network, increasing its viability.
The fifth and final day of DEVcon 0! Vitalik Buterin and Vlad Zamfir started off day five with a whiteboard presentation on Ethereum 1. There are several problems that need to be solved as blockchain technology moves forward in the future — scalability and blockchain interoperability being at the forefront of those issues.
The idea of Ethereum interacting with thousands of other blockchains is an attractive one, this in itself solves certain scalability problems in that work can distributed across many chains as opposed to bloating one central chain. Gavin then joined Vitalik and together they talked about the Ethereum Light-Client. A light client protocol is especially important for Ethereum as it will allow it to run on low capacity environments such as mobile phones, IoT Internet of Things devices and browser extensions.
The two explained the development process and usage of Patricia Merkle Trees to implement it. Expect the light client to be ready for the release of Ethereum 1. Mix is being developed in conjunction with Alethzero and expected to be released in the next 12 to 18 months. It supports a rather amazing feature set, including documentation, compiler and debugger integration as you type, information on code health, valid invariant, code structure and code formatting, as well as variable values and assertion truth annotations.
Finally, Vitalik wrapped up the event with a presentation showing some ideas for Ethereum 2. Amazing team, you are building the future of human, machine, and program interaction. You are the best!
