scalar-mult
Use scalar-mult to multiply a point that lies on the BN254 by a specified scalar integer value.
Basic syntax
To multiply a point by a specified scalar integer value, use the following syntax:
(scalar-mult type point1 scalar)
Arguments
Use the following arguments to specify the type, point, and scalar value for multiplication using the scalar-mult Pact function.
| Argument | Type | Description |
|---|---|---|
type | string | Specifies the type of point to multiply. The valid values are "g1" and "g2". |
point1 | point | Specifies the point on the BN254 curve to be multiplied. |
scalar | integer | Specifies the integer value to multiply the point by. |
Return value
The scalar-mult function returns the result of multiplying the specified point by the scalar value.
Examples
The following example demonstrates how to use the scalar-mult function to multiply the point { 'x: 1, 'y: 2 } on curve 'g1 by the scalar value 3:
pact> (scalar-mult 'g1 {'x: 1, 'y: 2} 3)
