 The curve instantiated by z is investigated by [\[PSNB\]](http://eprint.iacr.org/2010/429) for an efficient implementation.
 Our library implements a fast algorithm, which is proposed by [\[AKLGL\]](http://eprint.iacr.org/2010/526) for this curve.
 The performance of this library is competitive to the state-of-the-art implementation report in [\[ABLR\]](http://sac2013.irmacs.sfu.ca/slides/s1.pdf).
+The old parameters in \[BDMOHT\] are not used now.
 
 * __CurveSNARK__
 Support for the second curve builds on code provided by [SCIPR Lab](http://www.scipr-lab.org/) in [libsnark](https://github.com/scipr-lab/libsnark). The curve was specifically selected for speeding up __Succinct Non-interactive ARguments of Knowledge__ (SNARKs), which benefit from its high 2-adicity (see [\[BCGTV13\]](http://eprint.iacr.org/2013/507) and [\[BCTV14\]](http://eprint.iacr.org/2013/879)).
