Rc/andromeda #6747

AdoAdoAdo · 2025-01-28T14:20:07Z

Reasoning behind the pull request

Implementation of Andromeda consensus described here: https://agora.multiversx.com/t/mip-25-removing-confirmation-blocks-andromeda/482 :

removes block equivocation reasons
removes forking reasons
increases consensus size to 400/400 for all shards

Integration of the Andromeda consensus:

removes confirmation blocks - due to all of the above, finality for all blocks becomes instant
fixed ordering in consensus group during an epoch

Proposed changes

The equivalent consensus proofs are introduced for removing equivocation on voted blocks
Increase consensus size for shards and adapt the rating and rewards accordingly - uniform handling on all shards
Consensus state machine changed to reflect the usage of equivalent consensus proofs, removed consensus header interceptor and switched to general header interceptor.
Propagation of the proposed block directly to all interested shards, as the block will no longer be changed through consensus
Epoch trigger, block tracker, fork detector, notarization and execution rules changed to support instant finality.
New topic/requesters/resolvers/interceptors/storage/pool for equivalent consensus proofs and introduced anti flood protections
Delayed block data propagation adapted for equivalent proofs and instant finality
Adapted node network sync, import DB sync, bootstrapping from DB

Testing procedure

chaos testing - with the chaos testing framework
load testing - txgen scenarios
performance testing & analysis vs Spica - performance analysis framework with record-replay txgen scenarios
chain simulator tests
shadow fork testing
full automated functional testing & system tests
backup machines testing
full history nodes tests
reset heavy test
upgrade test
backwards compatibility (importDB) tests
half network upgrade system test
rosetta checks

Pre-requisites

Based on the Contributing Guidelines the PR author and the reviewers must check the following requirements are met:

was the PR targeted to the correct branch?
if this is a larger feature that probably needs more than one PR, is there a feat branch created?
if this is a feat branch merging, do all satellite projects have a proper tag inside go.mod?
