+## BLS12-381 aggregation
+
+CometBFT supports aggregation for BLS12-381 signatures. This drastically
+reduces the size of the blockchain and verification time.
+
+The aggregation won't work if vote extensions are enabled!
+
+To prevent [Rogue Key
+Attacks](https://hackmd.io/@benjaminion/bls12-381#Rogue-key-attacks) a proof of
+possession (PoP) must be required from validators upon the registration. This
+is left to the ABCI application to implement.

Subject: [PATCH 057/118] fix(e2e): fix BLS-related failures (#3726)

Part of #3720

`e2e` tests _require_ a method that generates a private key
deterministically (from a secret). Without such method, is it not
possible for the "tests" step of the `e2e` runner to recreate the node
structure as it exists within the runner itself.

Manual nightly runs:
- [1st
try](https://github.com/cometbft/cometbft/actions/runs/10424046666)
- [2nd
try](https://github.com/cometbft/cometbft/actions/runs/10424939531),
after 53321d4

---

- ~[ ] Tests written/updated~
- ~[ ] Changelog entry added in `.changelog` (we use
[unclog](https://github.com/informalsystems/unclog) to manage our
changelog)~
- ~[ ] Updated relevant documentation (`docs/` or `spec/`) and code
comments~
