- # Tendermint fork detection and IBC fork detection
-
- ## Status
-
- This is a work in progress.
- This directory captures the ongoing work and discussion on fork
- detection both in the context of a Tendermint light node and in the
- context of IBC. It contains the following files
-
- ### detection.md
-
- a draft of the light node fork detection including "proof of fork"
- definition, that is, the data structure to submit evidence to full
- nodes.
-
- ### [discussions.md](./discussions.md)
-
- A collection of ideas and intuitions from recent discussions
-
- - the outcome of recent discussion
- - a sketch of the light client supervisor to provide the context in
- which fork detection happens
- - a discussion about lightstore semantics
-
- ### [req-ibc-detection.md](./req-ibc-detection.md)
-
- - a collection of requirements for fork detection in the IBC
- context. In particular it contains a section "Required Changes in
- ICS 007" with necessary updates to ICS 007 to support Tendermint
- fork detection
-
- ### [draft-functions.md](./draft-functions.md)
-
- In order to address the collected requirements, we started to sketch
- some functions that we will need in the future when we specify in more
- detail the
-
- - fork detections
- - proof of fork generation
- - proof of fork verification
-
- on the following components.
-
- - IBC on-chain components
- - Relayer
-
- ### TODOs
-
- We decided to merge the files while there are still open points to
- address to record the current state an move forward. In particular,
- the following points need to be addressed:
-
- - <https://github.com/informalsystems/tendermint-rs/pull/479#discussion_r466504876>
-
- - <https://github.com/informalsystems/tendermint-rs/pull/479#discussion_r466493900>
-
- - <https://github.com/informalsystems/tendermint-rs/pull/479#discussion_r466489045>
-
- - <https://github.com/informalsystems/tendermint-rs/pull/479#discussion_r466491471>
-
- Most likely we will write a specification on the light client
- supervisor along the outcomes of
-
- - <https://github.com/informalsystems/tendermint-rs/pull/509>
-
- that also addresses initialization
-
- - <https://github.com/tendermint/spec/issues/131>
