Solidity Storage Array Bug Announcement This blog post is about two bugs connected to storage arrays which are otherwise unrelated. Both have been present in the compiler for a long time and have only been discovered now even though a contract containing them should very likely show malfunctions in tests. Daenam Kim with help from Nguyen Pham, both from Curvegrid discovered an issue where invalid data is stored in connection with arrays of signed integers. This bug has been present since Solidity 0.4.7 and we consider it the more serious of the two. If these arrays use negative integers in…

After many months of silence, we’re proud to announce the v1.9.0 release of Go Ethereum! Although this release has been in the making for a lot longer than we anticipated, we’re confident there will be some juicy feature for everyone to enjoy! Warning: We’ve tried our best to squash all the bugs, but as with all major releases, we advise everyone to take extra care when upgrading. The v1.9.0 release contains database schema changes, meaning it’s not possible to downgrade once updated. We also recommend a fresh fast sync as it can drastically reduce the database size. Some of the…

By now, we hope you’ve heard the news: In just two days, on July 17, 2019, the first wave of general Devcon tickets will go online at 6:00am PT / 9:00am ET / 3:00pm CEST / 10:00pm JST.

Further, we’ve maintained our limit of 20 tickets per organization to help as many teams as…

各位, With well under three months to go until Devcon, we are moving at full speed toward Osaka! You’ll hear about first programming details and more in the coming days, and with ticket sales now underway, we thought it time for a more formal update! First, Wave 2 of ticket sales are tentatively scheduled to take place on August 6th. We’ve learned and patched a lot following the last round. We used a new, open source ticketing platform this year, and while the platform itself performed admirably, we didn’t get everything right on our configurations for the first production run.…

各位, We are now fewer than 60 days away from Devcon, and we wanted to provide important updates and further details about how to obtain remaining Devcon tickets for everyone looking to join us in Osaka.

We are happy to announce the launch of a large-scale translation program for Ethereum.org, which will translate the website and other resources into more than 15 languages.

Today, we are thrilled to launch our first full translation: a Korean version of the website, available now at ethereum.org/ko. In the coming weeks, our program will expand with an…
