RequestMembership

To request membership, the prospective member needs to call requestMembership() function.

When the transaction is sucessful, whitelisters can start verification process. If the application is accepted, whitelisters can whitelistApplicant():

After two whitelisters approve the application, the account that initiated the membership request is ready to become a new member. The only step left is to pay the membership fee. It is sufficient for the account to transfer the required minimum amount of cryptocurrency (by default, ETH) along with the payMembershipFee() function.
