+### 2026-03-04: Treasury and Staking Rewards modalities
+
+We didn't get these right at the start. They should have been:
+
+| Modality                       | Start                  | Cliff                  | End                    |

+| Staking Rewards Year 3-6       | 2028-02-05T00:00:00Z   | 2028-03-05T00:00:00Z   | 2031-02-05T00:00:00Z   |
+| Staking Rewards Year 7 - 10    | 2031-02-05T00:00:00Z   | 2031-03-05T00:00:00Z   | 2035-02-05T00:00:00Z   |
+| Treasury                       | 2026-03-05T00:00:00Z   | 2026-04-05T00:00:00Z   | 2031-02-05T00:00:00Z   |

+
+The differences are:
+
+- The split on Staking Rewards is such that we can distribute different amounts
+  of tokens to time spans (instead of having a single sum over a single linear
+  vesting period).
+- The treasury is end date was one month too short.
+
+The beneficiary for all of those is 0xd5259b6E9D8a413889953a1F3195D8F8350642dE,
+idOS's main treasury wallet.
+
+Translating that to IDOSVesting constructor parameters, we get:
+
+| Modality                    | beneficiary                                | startTimestamp | durationSeconds | cliffSeconds |
