 #### BLS Signatures
 
-Eth2 makes use of BLS signatures as specified in the [IETF draft BLS specification](https://tools.ietf.org/html/draft-irtf-cfrg-bls-signature-02). Specifically, eth2 uses the `BLS_SIG_BLS12381G2_XMD:SHA-256_SSWU_RO_POP_` ciphersuite which implements the following interfaces:
