Methods

rnfElement → () Source #

Flat Element Source #

We don't support direct flat encoding of G1 elements because of the expense of on-chain uncompression. Users should convert between G1 elements and bytestrings using compress and uncompress: the bytestrings can be flat-encoded in the usual way.

hashToGroup ∷ ByteString → ByteString → Either BLS12_381_Error Element Source #

compressElement → ByteString Source #

Compress a G2 element to a bytestring. This serialises a curve point to its x coordinate only, using an extra bit to determine which of two possible y coordinates the point has. The compressed bytestring is 96 bytes long. See https://github.com/supranational/blst#serialization-format

uncompress ∷ ByteString → Either BLSTError Element Source #

Uncompress a bytestring to get a G2 point. This will fail if any of the following are true: * The bytestring is not exactly 96 bytes long * The most significant three bits are used incorrectly * The bytestring encodes a field element which is not the x coordinate of a point on the E2 curve * The bytestring does represent a point on the E2 curve, but the point is not in the G2 subgroup

offchain_zeroElement Source #

The zero element of G2. This cannot be flat-serialised and is provided only for off-chain testing.

compressed_zero ∷ ByteString Source #

The zero element of G2 compressed into a bytestring. This is provided for convenience in PlutusTx and is not exported as a builtin.

compressed_generator ∷ ByteString Source #

The standard generator of G2 compressed into a bytestring. This is provided for convenience in PlutusTx and is not exported as a builtin.

memSizeBytesInt Source #

Memory usage of a G2 point (288 bytes)

compressedSizeBytesInt Source #

Compressed size of a G2 point (96 bytes)
