• Proposal — action or items being proposed by users of the network

• Second — other stakeholders can second (approve) a proposal if they agree with it and want to help it reach public referenda. This requires matching the deposit of the original proposer

  So, if a user(creator of the proposal) has locked/deposited 100 BNC then anyone wanting to second the motion will need to lock in equal amount of BNC.

• Preimage hash — hash of the proposal to be enacted. The first step to make a proposal is to submit a preimage. The hash is just its identifier. The proposer of the preimage can be different than the user that proposes that preimage as a formal proposal

• Minimum preimage deposit — minimum amount of tokens that the proposer needs to pay when submitting a preimage

• Minimum proposal deposit — minimum amount of tokens that the proposer needs to bond when submitting a proposal. Tokens might be locked for an indeterminate amount of time because it is unknown when a proposal may become a referendum (if ever). This is true for tokens bonded by both the proposer and users that second the proposal(currently set at 100 BNC)

• Launch period — how often new public referenda are launched

• Cool-off period — duration (in blocks) in which a proposal may not be re-submitted after being vetoed

For Bifrost, the above parameters have the following values:
