Manual research claims

A manual research claim (MRC) is a way to be paid the research reward without staking a block yourself: the wallet asks the next staker to pay it as part of their block, for a fee. It is for researchers whose wallet is small or is not often open.

Gridcoin pays in two layers. The block reward goes to whoever stakes a block, so it depends on how often your wallet stakes. The research reward builds up with the time since your last payout and your magnitude, not with how often you stake: it waits for you. Staking pays it whole. If you stake rarely or your wallet is closed most of the time, an MRC pays only that second layer: you ask the next staker to include your claim in their block.

There is a fee. The wallet does not allow a claim inside the first 10 minutes after your last payout (the whole reward would be the fee). After that the fee is 40 % of the reward of those 10 minutes, a fixed amount, so as a share of what you claim it falls the longer you wait: fee = 40 % × 10 minutes ÷ the time since the last payout. Of every fee the foundation gets four fifths (the share was set by a poll) and the staker that includes the claim the rest. A claim cannot pay more than the accrual limit, two days of the highest magnitude a CPID can have, so a long wait can lose reward as well as pay less in fees.

From the wallet's rules (MRC::GetFee(), the foundation share and the output limit in its consensus reference). The figures below are what the chain has paid.

No claim waits. A block takes what has been sent about every 90 seconds, so this list is usually empty.
