Era switch to Pythagoras​

We have introduced the Pythagoras era in the Mithril networks. The switch to Pythagoras is a significant milestone that brings new features and improvements to the Mithril protocol.

danger

Mithril signer versions compatible with the new Pythagoras era are:

  • 0.2.221
  • 0.2.209
  • 0.2.200.

All other versions are not compatible with the new era and must be updated.

tip

You can easily update your Mithril signer with this one-line command (it will be downloaded to the current directory by default; you can specify a custom folder with the -p option):

curl --proto '=https' --tlsv1.2 -sSf https://raw.githubusercontent.com/input-output-hk/mithril/refs/heads/main/mithril-install.sh | sh -s -- -c mithril-signer -d latest -p $(pwd)

info

We use the era switch mechanism to introduce breaking changes in the Mithril protocol. Because these features are not backward compatible with the previous era, at least 95% of the stake must be running the new version for Pythagoras to activate. Refer to the Mithril network upgrade strategy ADR for more details.
