@@ -32,7 +32,7 @@ In this NEP we propose to add the following functions as precompile:
 - ***bls12381_g1_sum*** — the function which adds the points from G1 on an elliptic curve. This function is useful for the aggregation of private keys in BLS Signature. Can be used for simple addition in G1. Separate from multiexp function due to gas cost. A similar function exists in Near for BN254 curve[[10](https://github.com/near/NEPs/issues/98)].
 - ***bls12381_g2_sum*** — the function which adds the points from G2 on an elliptic curve. This function is useful for the aggregation of signatures in BLS Signature. Can be used for simple addition in G2. Separate from multiexp function due to gas cost.
 - ***bls12381_g1_multiexp —*** for points $g_i \in G_1$ and scalars $s_i$ calculate $\sum g_i s_i$. Can be used for multiplication on the scalar. Can be useful for zkSNARKs verification. This operation can be performed in a more optimized way than just straightforward multiplication and addition by using Pippenger algorithm[[25](https://github.com/wborgeaud/python-pippenger/blob/master/pippenger.pdf)]. A similar function exists both in Near for BN254[[10](https://github.com/near/NEPs/issues/98)] and in EIP-2537[[15](https://eips.ethereum.org/EIPS/eip-2537)].

 - ***bls12381_g1_map_to_curve —*** map base field element into the $G_1$ point. Doesn’t perform mapping of the byte string into field elements (can be done in different ways and quite fast). Transfer field element into a curve. It is necessary for signature schemes. Function from EIP-2537[[15](https://eips.ethereum.org/EIPS/eip-2537)].
 - ***bls12381_g2_map_to_curve —*** map extension field element into the $G_2$ point. Doesn’t perform mapping of the byte string into extension field elements. Function from EIP-2537[[15](https://eips.ethereum.org/EIPS/eip-2537)].
 - ***bls12381_g1_decompress —*** accepts points from $G_1$  in compressed form and returns in decompressed form. Some protocols provide points in compressed forms (for example, Light Client updates in Ethereum 2), and decompressing is a time-consuming operation. Other functions accept only decompressed points for simplicity and for gas consumption optimization.
