Ethereum: A Decentralized, Open-Source Blockchain is an open source, a distributed software platform that is based on blockchain technology. It has its own native cryptocurrency called Ethereum and a programming language called Solidity.

Ethereum’s website is not what you imagine when you think about the classic website. Most of its content is educational, often technical and aimed both at professionals and complete beginners, so the support of native language is super important for its visitors.

“We understood that we needed a localization tool that is easy to use, easy to get onboarded to and has an advanced functionality like translation memory and glossary, so we chose Crowdin.” Luka Kropec, Translation Project Lead at

Who And How Translates Content

Ethereum’s visitors and users are the people who do the translations, as the team chooses to combine translation by volunteers and proofreading by the agency in their translation strategy.

“We add new languages to Crowdin whenever there is a request. Now we enabled 87 target languages and 48 of them are live on our website.” Luka Kropec, Translation Project Lead at

The new language goes live as soon as all the content is translated. To prioritize certain pages and make it easier to manage the localization, created 19 folders, so community translators can work with them gradually, starting from the most important ones like the home page, site navigation, and other essential information.

As the website is open source, the content there changes often. Thus, the team chooses to update sources every month. Their workflow looks like this:

  1. At the beginning of the month, they update sources at Crowdin.
  2. Run the pre-translation by translation memory.
  3. The translators have time to translate new content. And whenever a folder is fully translated, the team orders proofreading from the translation agency.
  4. The team pulls all approved translations back to their website.

“The crowdsourcing and easy collaboration functionality that Crowdin offers is one of the main reasons we prefer Crowdin over other professional tools.” Luka Kropec, Translation Project Lead at

Video Localization with the Help of Video Preview App

Context is important to receive high-quality localization results. The screenshots, live previews and comments play an essential role for your translation team, saving their and managers’ time as well.

What if you need to localize video subtitles? The best decision would be to have this video open right in front of a translator. I hope you don’t think that we advise you to open your video in a separate browser tab and constantly click from tab to tab. The best option would be to do just like the team does – use our Video Preview app. The app allows you to specify the video URL for every file with subtitles and lets your translators preview the video during translation.

How Collaborates and Ensures Quality of Community Translations at Crowdin

Now, around 4000 people participate in the localization of content. Many companies probably dream of having so many people willing to help them localize their products. However, it’s important to keep in mind how hard it can be to manage such a number of people properly. The Ethereum team handle it with a bang. And all thanks to a few things:

Translation guides and terminology base

Besides general information that includes in the description of every translation project they have, the team also has a list of resources to help people jump into their translation workflow faster. They include the following:

The important part of their translation program is the project glossary. The team collected essential terms often found in the content and their translations from a few native speakers. Then they chose one variant of translations of the most frequent ones. Now, when translating content, users can use pre-selected translations for specific terms from the glossary.

Translation agency

To ensure the high quality of the content that appears on the website and other resources, the team does proofreading by a professional translation agency.

“We love Crowdin for the user management and ability to manage access levels, so everyone can do their job, and we won’t worry about problems with permissions.”

They onboarded a few managers from the agency to their translation projects, and that’s it. Managers simply invited their colleagues to projects as proofreaders, so they could start working on the tasks.

The right tool to collaborate

Crowdin allows you to translate online with all the benefits of a desktop CAT tool and be sure that you’re working on the latest file version. Translate, review, and manage your work in the cloud. Invite your colleagues to help and set up different permissions.
