Returns cost of the Poseidon hash function for the given number of inputs is determined by the following quadratic function:

61*n^2 + 542

Which aproximates the results of benchmarks of light-posiedon library[0]. These results assume 1 CU per 33 ns. Examples:

  • 1 input
    • light-poseidon benchmark: 18,303 / 33 ≈ 555
    • function: 61*1^2 + 542 = 603
  • 2 inputs
    • light-poseidon benchmark: 25,866 / 33 ≈ 784
    • function: 61*2^2 + 542 = 786
  • 3 inputs
    • light-poseidon benchmark: 37,549 / 33 ≈ 1,138
    • function; 61*3^2 + 542 = 1091
