Typedef Documentation

typedef struct scv_profile_ scv_profile

Usage:

On any [service] node that participates in Service / Path verfication:

Step 1: Initialize this library by calling scv_init() Step 2: Setup a Service chain validation profile that contains all the parameters needed to compute cumulative: Call these functions: scv_profile_find scv_profile_create scv_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: scv_set_validator Step 3a: At the initial Service node to generate Random number that will be read by all other nodes: scv_generate_random Step 3b: At all service nodes including initial and verifier call this to compute cumulative: scv_update_cumulative Step 4: At the verifier: scv_validate
