**Overview:** Adding an extra malus variant focusing on disputing finalized blocks. It will: - wrap around approval-voting - listen to `OverseerSignal::BlockFinalized` and when encountered start a dispute for the `dispute_offset`th ancestor - simply pass through all other messages and signals Add zombienet tests testing various edgecases: - disputing freshly finalized blocks - disputing stale finalized blocks - disputing eagerly pruned finalized blocks (might be separate PR) **TODO:** - [x] Register new malus variant - [x] Simple pass through wrapper (approval-voting) - [x] Simple network definition - [x] Listen to block finalizations - [x] Fetch ancestor hash - [x] Fetch session index - [x] Fetch candidate - [x] Construct and send dispute message - [x] zndsl test 1 checking that disputes on fresh finalizations resolve valid Closes #1365 - [x] zndsl test 2 checking that disputes for too old finalized blocks are not possible Closes #1364 - [ ] zndsl test 3 checking that disputes for candidates with eagerly pruned relay parent state are handled correctly #1359 (deferred to a separate PR) - [x] Unit tests for new malus variant (testing cli etc) - [x] Clean/streamline error handling - [ ] ~~Ensure it tests properly on session boundaries~~ --------- Co-authored-by: Javier Viola <javier@parity.io> Co-authored-by: Marcin S. <marcin@realemail.net> Co-authored-by: Tsvetomir Dimitrov <tsvetomir@parity.io>
NOTE: We have recently made significant changes to our repository structure. In order to streamline our development process and foster better contributions, we have merged three separate repositories Cumulus, Substrate and Polkadot into this repository. Read more about the changes here.
Polkadot SDK
The Polkadot SDK repository provides all the resources needed to start building on the Polkadot network, a multi-chain blockchain platform that enables different blockchains to interoperate and share information in a secure and scalable way. The Polkadot SDK comprises three main pieces of software:
Polkadot
Implementation of a node for the https://polkadot.network in Rust, using the Substrate framework. This directory
currently contains runtimes for the Polkadot, Kusama, Westend, and Rococo networks. In the future, these will be
relocated to the runtimes repository.
Substrate
Substrate is the primary blockchain SDK used by developers to create the parachains that make up the Polkadot network. Additionally, it allows for the development of self-sovereign blockchains that operate completely independently of Polkadot.
Cumulus
Cumulus is a set of tools for writing Substrate-based Polkadot parachains.
