### Description
|
|
|
|
|
|
|
|
|
|
Currently, RLN v1 allows for a fixed message rate of 1/msg per epoch while RLN v2 allows for n msgs/epoch.
|
|
|
|
|
The goal of this milestone is designing the key derivation and related cryptographic components for allowing several n msgs/epoch constraints.
|
|
|
|
|
For example: 24 msg / day && 1 msg/10 seconds.
|
|
|
|
|
|
|
|
|
|
* the nullifier defined in the [RLN RFC](https://rfc.vac.dev/spec/32/#slashing-and-shamirs-secret-sharing) has to be adapted accordingly.
|
|
|
|
|
|
|
|
|
|
### Justification
|
|
|
|
|
|
2024-05-02 14:10:28 +05:30
|
|
|
Dynamic epoch sizes are required for users who have smaller messaging needs, to optimize for stake used.
|
|
|
|
|
rln-v3 will allow that.
