Summary

This MIP introduces the Informer as proposed by the Biarritz Model.

The informer provides an estimate of the circulating $L1MOVE and $L2MOVE tokens. It acknowledges that the measured value will be off due to

  • inflight tokens
  • differences in the clock of different layers

However it provides some bounds and approaches to get an estimate that should not be too far off.

MIP-57


We refer to the following illustration for a bridge transfer from L1 to L2, which is taken from [MIP-39](https://github.com/movementlabsxyz/MIP/pull/39).

@apenzk The content of the MIP still references the HTLV bridge at some locations. We may replace them with to acknowledge the new architecture?


## Abstract

The Informer for the HTLC-based Native Bridge (in the following called simply the Native Bridge) is introduced to collect information about the state from L1 and L2 and provide this information to components of the Native Bridge. The provided information is critical to the safe operation of bridge components such as the Rate-Limiter, the Security Fund, and the Bridge Operator.
