Boosting allows Grain holders to signal high value things that merit the SourceCred community’s attention. Grain holders do this by staking their Grain to a node to boost it. When things are boosted those who contribute to or engage with those things will earn more Cred because the amount of Cred flowing to that node is boosted. Whoever boosted a node loses their Grain, but they gain a percentage of the Cred that will flow through the node. This incentivizes people to only boost things they think will actually be valuable and produce more Cred in the future, and it incentivizes the community to pay attention to things that are boosted because they will get more Cred for doing so.
