blst safety advisory

Although there’s at the moment no identified sensible exploit of this situation, it’s suggested that everybody operating beacon chain purchasers improve to the most recent model in case an exploit is uncovered. Similarly, in case you use blst in your undertaking, we extremely suggest bumping to the most recent model as quickly as doable.

[Note: Teku was not running an affected version of blst, but they have some juicy optimizations recently so you might as well upgrade anyway]

You can learn extra about this situation within the public safety advisory on the blst repo.
