WebThus a commitment to 19.1 bits requires at most lpl+2 log IqI bits. Furthermore, by first computing the product gh a commitment to s can be done in less than 21q1 multiplications modulop or less than two multiplications pr. bit of s. Thus the commitment scheme is quite efficient with respect to the size of
