Commit IPP & register

Pressing register will freeze 10 IPP from your ledger as a stake. Upon successful dual-QR check-in/check-out the stake is returned and a reward of 25 IPP is credited, leaving a net change of +25 IPP. Failure to complete the dual-QR within the window forfeits the stake (non-recoverable, per Whitepaper §3.4 / D-016).

IPP commitments are non-recoverable. Failure to submit verifiable evidence forfeits the burn. Whitepaper §3.4
