Typedef Documentation

pot_profile

typedef struct pot_profile_ pot_profile

Usage:

On any node that participates in Proof of Transit:

Step 1: Initialize this library by calling pot_init() Step 2: Setup a proof of transit profile that contains all the parameters needed to compute cumulative: Call these functions: pot_profile_find pot_profile_create pot_profile_set_bit_mask - To setup how large we want the numbers used in the computation and random number <= 64 bits Step 2a: For validator do this: pot_set_validator Step 2b: On initial node enable the profile to be used: pot_profile_set_active / pot_profile_get_active will return the profile Step 3a: At the initial node to generate Random number that will be read by all other nodes: pot_generate_random Step 3b: At all nodes including initial and verifier call this to compute cumulative: pot_update_cumulative Step 4: At the verifier: pot_validate
