The founding members at the time of creation of a network or a channel must also define the policy on how new members will be admitted into the network or a channel. By default, this policy is simply the one chosen by the majority (namely two out of two, two out of three, three out of four, and so on). The members may decide on any other policy for admitting new members in the network. Any change in the policy to admit new members will typically be decided through a business agreement. Once an agreement is reached, the channel configuration can be updated per the current policy to reflect the new policy for admitting new members.
