blst safety advisory

[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 may learn extra about this subject within the public safety advisory on the blst repo.
Beacon Chain safety+testing RfP
Reminder! There’s an excellent Beacon Chain safety+testing RfP.
The EF is on the lookout for any proposals that additional the safety and robustness of the Beacon Chain and the upcoming merge (migration from PoW to PoS). Reside community evaluation, formal verification, shopper load testing, new consensus vectors — simply to call a number of potential paths.
