 #### ABI for G2 multiexponentiation
 
-G2 multiexponentiation call expects `288*k` bytes as an input that is interpreted as byte concatenation of `k` slices each of them being a byte concatenation of encoding of G2 point (`256` bytes) and encoding of a scalar value (`32` bytes). Output is an encoding of multiexponentiation operation result - a single G2 point (`256` bytes).
