Today, our regular all-team update series is relaunching in a changed and ever growing ecosystem.

A number of improvements to LES code structure and robustness are in the Geth pull-request pipeline (big shout out to Gary Rong) addressing immediate concerns, while the long term direction is being researched and established.

Some teasers that we&#8217;ve dropped along the way revolve around significant <a target=\"_blank\" rel=\"noopener\" class=\"chakra-link css-vezwxf\" href=\"https:\/\/twitter.com\/peter_szilagyi\/status\/1110487398926950400\">performance improvements<\/a> for archive nodes and significant <a target=\"_blank\" rel=\"noopener\" class=\"chakra-link css-vezwxf\" href=\"https:\/\/twitter.com\/peter_szilagyi\/status\/1118420506993156096\">storage reductions<\/a> for full nodes. These seem to be confirmed by <a target=\"_blank\" rel=\"noopener\" class=\"chakra-link css-vezwxf\" href=\"https:\/\/twitter.com\/LedgerQL\/status\/1114478908219514880\">external<\/a> entities <a target=\"_blank\" rel=\"noopener\" class=\"chakra-link css-vezwxf\" href=\"https:\/\/twitter.com\/eduadiez\/status\/1114167656628871168\">too<\/a>, so we&#8217;re really happy about them. We&#8217;ve also been working on a new database format that permits moving a large chunk (estimated at \u2154, per a recent benchmark) of the data of a full node (not archive) onto a HDD, making it easier and more cost efficient to run Ethereum nodes.<\/p>\n<p class=\"chakra-text css-gi02ar\">Lower level networking: the team&#8217;s been focusing on the new discovery specs (ENR and company), with the aim to replace both the old v4 (used by full node) as well as the hacky v5 (used by Geth light clients). This will be the first real upgrade of this infrastructure in the last 4 years, so we have a lot of lessons to incorporate. The aim is to build a much more robust system that can support coexistence of higher level protocols (les) and multiple Ethereum networks (mainnet, testnets, etc).<\/p>\n<p class=\"chakra-text css-gi02ar\">Higher level networking: the light client protocol sports transaction lookups by hash and new RPC APIs to support priority service to paying customers. The team reviewed directions for the LES and PIP protocols, and have agreed to start to establish common directions between Geth and Parity. The first cross-team meeting is coming up in May.<\/p>\n<p class=\"chakra-text css-gi02ar\">We&#8217;ve also focused on separating account management out of Geth into its own signer application called Clef. The first release will be CLI only, but we&#8217;ve been working on multiple proof of concept UIs to make sure we and others can build on top of the building blocks Clef provides. Clef&#8217;s goal is to provide a secure way to manage your Ethereum accounts that can handle both keys as well as hardware wallets; but most importantly, one that can be used by all DApps on your system without each having to roll their own accounts handling!<\/p>\n<p class=\"chakra-text css-gi02ar\">Other smaller features we&#8217;ve been working on include a GraphQL-based API for querying chain data, built in support for smart card wallets, updated Ledger support, Prometheus monitoring support (in addition to InfluxDB which we&#8217;ve already rolled out), BlockScout integration into Puppeth, and more.<\/p>\n<p class=\"chakra-text css-gi02ar\">As we&#8217;re drawing eerily close to the 1.9.0 release, we&#8217;ve kept this section shorter and will do an expanded blog post in the following couple of weeks!<\/p>\n<h2 class=\"chakra-heading group css-1kpzc4q\" id=\"grid\" data-group=\"true\"><a class=\"chakra-link css-128fqrf\" aria-label=\"grid permalink\" href=\"#grid\"><svg viewbox=\"0 0 24 24\" focusable=\"false\" class=\"chakra-icon css-173jpr1\"><g fill=\"currentColor\"><path d=\"M10.458,18.374,7.721,21.11a2.853,2.853,0,0,1-3.942,0l-.892-.891a2.787,2.787,0,0,1,0-3.941l5.8-5.8a2.789,2.789,0,0,1,3.942,0l.893.892A1,1,0,0,0,14.94,9.952l-.893-.892a4.791,4.791,0,0,0-6.771,0l-5.8,5.8a4.787,4.787,0,0,0,0,6.77l.892.891a4.785,4.785,0,0,0,6.771,0l2.736-2.735a1,1,0,1,0-1.414-1.415Z\"\/><path d=\"M22.526,2.363l-.892-.892a4.8,4.8,0,0,0-6.77,0l-2.905,2.9a1,1,0,0,0,1.414,1.414l2.9-2.9a2.79,2.79,0,0,1,3.941,0l.893.893a2.786,2.786,0,0,1,0,3.942l-5.8,5.8a2.769,2.769,0,0,1-1.971.817h0a2.766,2.766,0,0,1-1.969-.816,1,1,0,1,0-1.415,1.412,4.751,4.751,0,0,0,3.384,1.4h0a4.752,4.752,0,0,0,3.385-1.4l5.8-5.8a4.786,4.786,0,0,0,0-6.771Z\"\/><\/g><\/svg><\/a>Grid<\/h2>\n<p class=\"chakra-text css-gi02ar\">The Mist Browser was <a target=\"_blank\" rel=\"noopener\" class=\"chakra-link css-vezwxf\" href=\"https:\/\/medium.com\/@avsa\/sunsetting-mist-da21c8e943d2\">sunset<\/a>, but <a target=\"_blank\" rel=\"noopener\" class=\"chakra-link css-vezwxf\" href=\"https:\/\/medium.com\/ethereum-grid\/introducing-ethereum-grid-1e65e7fb771e\">Ethereum Grid<\/a> was born. <a target=\"_blank\" rel=\"noopener\" class=\"chakra-link css-vezwxf\" href=\"https:\/\/github.com\/ethereum\/grid\">Grid<\/a> is a desktop application that allows users to securely download, configure and use various clients and tools in the Ethereum ecosystem.

We&#8217;ve also been working on making the code base more modular to increase maintainability and code reuse between the Ethereum 1.0 and 2.0 parts of the code base. Trinity continues to improve its event-driven architecture and extensibility support.<\/p>\n<p class=\"chakra-text css-gi02ar\">Additionally, Trinity has received many updates working towards a first Ethereum 2.0 testnet. We continue to collaborate with the research team to integrate Eth2 into Trinity.<\/p>\n<p class=\"chakra-text css-gi02ar\">In Eth1.0 news: we&#8217;re currently experimenting with a new feature we call Beam Sync. Imagine starting a Trinity node and having it start processing the latest blocks and serving RPC requests within minutes. Beam Sync will verify blocks as they&#8217;re mined by prioritizing sync of the state used in the latest blocks.<\/p>\n<p class=\"chakra-text css-gi02ar\">And finally on the Eth1.x front, we&#8217;ve been working on the <a target=\"_blank\" rel=\"noopener\" class=\"chakra-link css-vezwxf\" href=\"https:\/\/notes.ethereum.org\/M7DM44r1SWqUBs0wrDi8_Q\">Firehose Sync protocol<\/a>, a new state sync protocol which will radically decrease the amount of time it takes to start a node and download all the data needed to be a first-class node on the Ethereum network. Firehose and Beam Sync enhance each other. Beam Sync is possible with the current network, but will be dramatically improved with the Firehose Sync protocol.<\/p>\n<h3 class=\"chakra-heading group css-xuzltg\" id=\"ewasm-1\" data-group=\"true\"><a class=\"chakra-link css-128fqrf\" aria-label=\"ewasm 1 permalink\" href=\"#ewasm-1\"><svg viewbox=\"0 0 24 24\" focusable=\"false\" class=\"chakra-icon css-173jpr1\"><g fill=\"currentColor\"><path d=\"M10.458,18.374,7.721,21.11a2.853,2.853,0,0,1-3.942,0l-.892-.891a2.787,2.787,0,0,1,0-3.941l5.8-5.8a2.789,2.789,0,0,1,3.942,0l.893.892A1,1,0,0,0,14.94,9.952l-.893-.892a4.791,4.791,0,0,0-6.771,0l-5.8,5.8a4.787,4.787,0,0,0,0,6.77l.892.891a4.785,4.785,0,0,0,6.771,0l2.736-2.735a1,1,0,1,0-1.414-1.415Z\"\/><path d=\"M22.526,2.363l-.892-.892a4.8,4.8,0,0,0-6.77,0l-2.905,2.9a1,1,0,0,0,1.414,1.414l2.9-2.9a2.79,2.79,0,0,1,3.941,0l.893.893a2.786,2.786,0,0,1,0,3.942l-5.8,5.8a2.769,2.769,0,0,1-1.971.817h0a2.766,2.766,0,0,1-1.969-.816,1,1,0,1,0-1.415,1.412,4.751,4.751,0,0,0,3.384,1.4h0a4.752,4.752,0,0,0,3.385-1.4l5.8-5.8a4.786,4.786,0,0,0,0-6.771Z\"\/><\/g><\/svg><\/a>eWASM<\/h3>\n<p class=\"chakra-text css-gi02ar\">We have also been laying some groundwork for eWASM in the last months.

Over the coming months, we expect to see short-lived, and then long-lived, multi-client public testnets.<\/p>\n<p class=\"chakra-text css-gi02ar\">Much of the Phase 0 work is now in the client teams&#8217; hands to bring the beacon chain to production. The client to do list includes: consensus tests, optimizations, efficient aggregation, stable p2p networks, state sync, validator UI\/UX, security reviews, visualizations tools&#8230; Thank (or fund!) your local client team next time you get a chance. They are the unsung heroes in this process and deserve much more support and praise.<\/p>\n<p class=\"chakra-text css-gi02ar\">Phase 1<\/p>\n<p class=\"chakra-text css-gi02ar\">The Phase 1 spec on <a target=\"_blank\" rel=\"noopener\" class=\"chakra-link css-vezwxf\" href=\"https:\/\/github.com\/ethereum\/eth2.0-specs\/blob\/dev\/specs\/core\/1_shard-data-chains.md\">shard data chains<\/a> is primarily in place and has gone through many simplifications the past few months. Most of these simplifications manifest in the &#8220;<a target=\"_blank\" rel=\"noopener\" class=\"chakra-link css-vezwxf\" href=\"https:\/\/github.com\/ethereum\/eth2.0-specs\/blob\/dev\/specs\/core\/1_custody-game.md\">custody game<\/a>&#8220;, reducing the complexity of computation and the complexity of the challenge games when unavailable data. The custody game is now more multi-party computation friendly to help encourage decentralized staking pools.<\/p>\n<p class=\"chakra-text css-gi02ar\">Recently Phase 1 was made executable and has been integrated into the spec test suite. This specification is to be iterated upon, simplified, and prototyped in the coming months.<\/p>\n<p class=\"chakra-text css-gi02ar\">Phase 2<\/p>\n<p class=\"chakra-text css-gi02ar\">Phase 2 has some exciting research underway. There has been much effort in simplifying and abstracting the execution consensus layer through a new path called &#8220;<a target=\"_blank\" rel=\"noopener\" class=\"chakra-link css-vezwxf\" href=\"https:\/\/ethresear.ch\/t\/proposed-further-simplifications-abstraction-for-phase-2\/5445\">execution environments<\/a>&#8220;. Execution environments open up a world of possibility in how the highly scalable data layer of Eth 2.0 might be used. In particular, it might allow us to slot Eth1 into Eth2 to enable a more seamless transition for the community. Much of the research and debate on Phase 2 is happening on <a target=\"_blank\" rel=\"noopener\" class=\"chakra-link css-vezwxf\" href=\"http:\/\/ethresear.ch\/\">http:\/\/ethresear.ch\/<\/a> so check it out!<\/p>\n<p class=\"chakra-text css-gi02ar\">Light clients<\/p>\n<p class=\"chakra-text css-gi02ar\">A <a target=\"_blank\" rel=\"noopener\" class=\"chakra-link css-vezwxf\" href=\"https:\/\/github.com\/ethereum\/eth2.0-specs\/blob\/dev\/specs\/light_client\/sync_protocol.md\">light client specification<\/a> relying upon Phase 1 exists and will be iteratively worked on in the coming quarter. We hope to see a couple of light client implementations being worked on in Q3 or Q4 after the core beacon chain implementations stabilize.<\/p>\n<h2 class=\"chakra-heading group css-1kpzc4q\" id=\"security-security--consensus-tests\" data-group=\"true\"><a class=\"chakra-link css-128fqrf\" aria-label=\"security security  consensus tests permalink\" href=\"#security-security--consensus-tests\"><svg viewbox=\"0 0 24 24\" focusable=\"false\" class=\"chakra-icon css-173jpr1\"><g fill=\"currentColor\"><path d=\"M10.458,18.374,7.721,21.11a2.853,2.853,0,0,1-3.942,0l-.892-.891a2.787,2.787,0,0,1,0-3.941l5.8-5.8a2.789,2.789,0,0,1,3.942,0l.893.892A1,1,0,0,0,14.94,9.952l-.893-.892a4.791,4.791,0,0,0-6.771,0l-5.8,5.8a4.787,4.787,0,0,0,0,6.77l.892.891a4.785,4.785,0,0,0,6.771,0l2.736-2.735a1,1,0,1,0-1.414-1.415Z\"\/><path d=\"M22.526,2.363l-.892-.892a4.8,4.8,0,0,0-6.77,0l-2.905,2.9a1,1,0,0,0,1.414,1.414l2.9-2.9a2.79,2.79,0,0,1,3.941,0l.893.893a2.786,2.786,0,0,1,0,3.942l-5.8,5.8a2.769,2.769,0,0,1-1.971.817h0a2.766,2.766,0,0,1-1.969-.816,1,1,0,1,0-1.415,1.412,4.751,4.751,0,0,0,3.384,1.4h0a4.752,4.752,0,0,0,3.385-1.4l5.8-5.8a4.786,4.786,0,0,0,0-6.771Z\"\/><\/g><\/svg><\/a>Security [Security \/ Consensus Tests]<\/h2>\n<p class=\"chakra-text css-gi02ar\">We have performed quite extensive metering of the execution of opcodes within Geth, to provide background and analysis for <a target=\"_blank\" rel=\"noopener\" class=\"chakra-link css-vezwxf\" href=\"https:\/\/eips.ethereum.org\/EIPS\/eip-1884\">https:\/\/eips.ethereum.org\/EIPS\/eip-1884<\/a>, which aims to rebalance opcodes that will otherwise lead to severe degradation of the Ethereum network.<\/p>\n<p class=\"chakra-text css-gi02ar\">The hive framework has been updated, and is again running on <a target=\"_blank\" rel=\"noopener\" class=\"chakra-link css-vezwxf\" href=\"https:\/\/hivetests.ethstats.net\">https:\/\/hivetests.ethstats.net<\/a>\/, and we have also re-launched a libfuzzer-based geth\/parity differential fuzzer in a production environment.

Our goal is to provide zkrollup as a proof of concept and then start to explore scaling other kinds of dapps in this way.<\/p>\n<p class=\"chakra-text css-gi02ar\">High level languages are starting to mature which allow developers to build scalable dapps using snarks with less ramp up time.

Together with other useful building blocks, these are now available as part of the ZoKrates standard library. This is accompanied by a new Python library called pycrypto which contains application code that makes it easy to interact with provable ZoKrates programs.<\/p>\n<p class=\"chakra-text css-gi02ar\">To make the most of these building blocks, we&#8217;ve improved optimizations for the ZoKrates compiler and started refactoring the module system to better support composition.<\/p>\n<p class=\"chakra-text css-gi02ar\">We have also specified the ZoKrates DSL grammar formally and are currently working on a more efficient parser implementation based on that specification.<\/p>\n<p class=\"chakra-text css-gi02ar\">As a step towards our goal of a Rust-only codebase, we added support for Bellman which enabled Mac OS X native builds as well as efficiency gains.<\/p>\n<p class=\"chakra-text css-gi02ar\">Finally, we extended our documentation (e.g., tutorial on how to proof pre-images of hashes) and released a blogpost which discusses the challenges of using zkSNARKs in dApps. For developer education, we conducted a workshop at the 2nd ZKProof Workshop, Berkeley. Further workshops are taking place in London and Split in June.<\/p>\n<\/div>\n<p><script async src=\"\/\/platform.twitter.com\/widgets.js\" charset=\"utf-8\"><\/script><br \/>\n<br \/><br \/>\n<br \/><a href=\"https:\/\/blog.ethereum.org\/en\/2019\/06\/21\/ef-supported-teams-development-report-2019-pt-1\">Source link <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Friends, Over the last year, developers and researchers supported by Ethereum Foundation have kept their heads down and continued to produce at a staggering pace.
