Crate noble_tips[][src]

Tipping Module ( noble-tips )

NOTE: This noble is tightly coupled with noble-treasury.

A subsystem to allow for an agile “tipping” process, whereby a reward may be given without first having a pre-determined stakeholder group come to consensus on how much should be paid.

A group of Tippers is determined through the config Config. After half of these have declared some amount that they believe a particular reported reason deserves, then a countdown period is entered where any remaining members can declare their tip amounts also. After the close of the countdown period, the median of all declared tips is paid to the reported beneficiary, along with any finders fee, in case of a public (and bonded) original report.


Tipping protocol:

  • Tipping: The process of gathering declarations of amounts to tip and taking the median amount to be transferred from the treasury to a beneficiary account.
  • Tip Reason: The reason for a tip; generally a URL which embodies or explains why a particular individual (identified by an account ID) is worthy of a recognition by the treasury.
  • Finder: The original public reporter of some reason for tipping.
  • Finders Fee: Some proportion of the tip amount that is paid to the reporter of the tip, rather than the main beneficiary.

Autogenerated weights for noble_tips



An open tipping “motion”. Retains all details of a tip including information on the finder and the members who have voted.


Simple preimage lookup from the reason’s hash to the original data. Again, has an insecure enumerable hash since the key is guaranteed to be the result of a secure hash.


TipsMap that are not yet completed. Keyed by the hash of (reason, who) from the value. This has the insecure enumerable hash function since the key itself is already guaranteed to be a secure hash.
