Upcoming update for the Trustlines Blockchain validators

Hello all,

The developers working on the Trustlines Protocol have been following the progress of Open Ethereum and are now proposing a change to start using Open Ethereum v3.1.0 instead of Parity 2.3.6.

We will be moving from the previously used Parity software to the newer Open Ethereum client. This change follows the announcement of Parity transitioning the development of the Parity Ethereum client to the new DAO.

The Parity Ethereum codebase and maintenance will be transitioned to a DAO ownership and maintainer model. We hope this new model can provide the basis for cross-organization collaboration to ensure the codebase gets the attention it needs to realize its full potential.

Open Ethereum has then become overseen by Gnosis to continue development of the former Parity Ethereum client.

Earlier this year, OE had a Release Candidate come out, and now a stable version has been released.

The validator node databases will automatically be migrated to version 16 via the db migration tool developed by the Open Ethereum team.

This proposed change will be implemented soon. The validators who have auto-updates turned on will receive them at that time. Others will need to do the change manually on their nodes.

The exact date and time will be posted soon here.

Further details can be found in the following post.


The update will take place at 12 pm CET on Friday the 18th of December, 2020.

The validators that have auto-update enabled will receive the update automatically.

Others will need to perform the upgrade manually. If you are using Docker, you will find the updated image here around Thursday this week.

Details of the update can be found at https://github.com/trustlines-protocol/blockchain/tree/tlbc-node/release.

This update does not contain changes to the chain specifications. It thus should have minimal effect on the Trustlines Blockchain’s performance.

One more thing. After the update today, validators will need to restart Netstats for Open Ethereum to be shown as the client instead of Parity.
