+# Activity Streak Program
+
+The purpose of the activity streak program is to reward loyal, active traders with the following tiered benefits:
+
+- a greater share of rewards schemes
+- an accelerated vesting rate on locked rewards
+
+Parties access higher tiers and greater benefits by maintaining an activity streak. The length of a streak is measured in epochs and a party is considered active if they made a trade or held an open position during the epoch. If a party is inactive for more than a specified number of epochs they lose their streak.
+
+## Network parameters
+
+- `rewards.activityStreak.benefitTiers`: is an ordered list of dictionaries defining the requirements and benefits for each tier.
+- `rewards.activityStreak.inactivityLimit`: the maximum number of epochs a trader can be inactive before loosing their streak.
+- `rewards.activityStreak.minQuantumOpenVolume`: the minimum open notional volume (expressed in quantum) for a trader to be considered active in an epoch
+- `rewards.activityStreak.minQuantumTradeVolume`: the minimum trade volume (expressed in quantum) for a trader to be considered active in an epoch
+
+
+## Governance proposals
+
+The network parameter [`rewards.activityStreak.benefitTiers`](#network-parameters) can be updated via a `UpdateNetworkParameter` governance proposal. Each tier in the ordered list must have the following fields:
+
+- `minimum_activity_streak`: int greater or equal to `0` defining the minimum activity streak a party must have to access this tier
+- `reward_multiplier`: float greater or equal to `1` defining the factor to scale a parties [reward shares]() by
+- `vesting_multiplier`: float greater or equal to `1` defining the factor to scale a parties [base vesting rate]() by
+
+*Example:*
+```proto
+message UpdateNetworkParameter{
+    changes: NetworkParameter{
+        key: "rewards.activityStreak.benefitTiers",
+        value: [
+            {"minimum_activity_streak": 1, "reward_multiplier": 1.0, "vesting_multiplier": 1.05},
+            {"minimum_activity_streak": 7, "reward_multiplier": 5.0, "vesting_multiplier": 1.25},
+            {"minimum_activity_streak": 31, "reward_multiplier": 10.0, "vesting_multiplier": 1.50},
+            {"minimum_activity_streak": 365, "reward_multiplier": 20.0, "vesting_multiplier": 2.00},
+
+        ],
+    }
+}
+```
+
+## Activity streak mechanics
+
+The following steps should occur **before** rewards are [distributed] and [vested].
+
+### Setting activity / inactivity streak
+
+For the feature, the network must track each parties "activity streak". At the end of an epoch:
+
+- if a party was "active" in the epoch
+
+    - increment their `activity_streak` by `1`
+    - reset their `inactivity_streak` to `0`.
+
+- if a party was "inactive" in the epoch
+
+    - increment their `inactivity_streak` streak by `1`
+    - if their `inactivity_streak` is greater than or equal to the `rewards.activityStreak.streakLength`, reset their `activity_streak` to `0`.
+
+A party is defined as active if they fulfil **either** of the following criteria:
+
+- their open interest was strictly greater than `rewards.activityStreak.minQuantumOpenVolume` at any point in the epoch
+- their total trade volume was strictly greater than `rewards.activityStreak.minQuantumTradeVolume` at the end of the epoch
+
+### Setting activity benefits
+
+After determining a parties "activity streak" there `reward_distribution_activity_multiplier` and `reward_vesting_activity_multiplier` should be set according to the highest tier they qualify for.
+
+```pseudo
+Given:
+    rewards.activityStreak.benefitTiers: [
+        [
+            {"minimum_activity_streak": 1, "reward_multiplier": 1.0, "vesting_multiplier": 1.05},
+            {"minimum_activity_streak": 7, "reward_multiplier": 5.0, "vesting_multiplier": 1.25},
+            {"minimum_activity_streak": 31, "reward_multiplier": 10.0, "vesting_multiplier": 1.50},
+            {"minimum_activity_streak": 365, "reward_multiplier": 20.0, "vesting_multiplier": 2.00},
+
+        ],
+    ]
+
+And:
+    activity_streak=48
+    inactivity_streak=3
+
+Then:
+    reward_distribution_activity_multiplier=10.0
+    reward_vesting_activity_multiplier=1.50
+```
+
+### Applying activity benefits
+
+#### Applying the activity reward multiplier
+
+The `activity_streak_reward_multiplier` scales the parties [reward share]() for all rewards they are eligible for.
+
+#### Applying the activity vesting multiplier
+
+The `activity_streak_vesting_multiplier` scales the parties [vesting rate]() of all funds locked in the parties vesting accounts.
+
+
+## APIs
+
+### Parties API
+
+Must expose the following:
+
+- a parties `activity_streak`
+- a parties `inactivity_streak`
+- whether a party has been considered "active" in the current epoch
+- a parties current `reward_distribution_activity_multiplier`
+- a parties current `reward_vesting_activity_multiplier`
+
+## Acceptance Criteria
+
+### Governance proposals
+
+TBD
+
+### Setting activity / inactivity streak
+
+TBD
+
+### Setting activity benefits
+
+TBD
