    Suspect that this is caused by a runtime upgrade changing the epoch duration introduced by #436

  • Why nextFeeMultiplier is -1 in Kusama and Crab

    Why nextFeeMultiplier is -1 in Kusama and Crab

    Queried value from chain state is Fixed128 -1,000,000,000,000,000,000

    Fixed128 is a signed fixed-point number with fixed-point accuracy of 10 ** 18, so it is -1 actrully, and removed all length fee and weight fee as a result, only base fee are computed.

  • Final Check List

    Final Check List

    Code Hygiene + Genesis

    • [x] Ensure that you are using a stable Substrate release.
    • [x] Avoid using experimental or untested features of Substrate on genesis.
    • [x] Avoid deviating from defaults, especially in consensus-relevant code, unless you have a strong understanding of the side-effects.
    • [x] If you have a custom SessionManager in your runtime, and are using frame_session, ensure/verify that it always gives the session module a complete set of keys.
    • [x] Validate/audit your chainspec - ensure all configs are set and all values are correct (as expected in terms of data types and defaults).
    • [x] Validator Nodes in config should all have all required session keys - session keys in config should all be present on a node.
    • [x] Sessions keys in config and in the runtime should be in the same order.
    • [x] Sanity Check: Can you achieve finality with the number of validators you control at genesis?
    • [x] Ensure as many dependencies as possible are crates following semver.
    • [x] Sanity check your block time/slot length and session/epoch length - if you have too few blocks for a given validator set/session, sync will be slowed - and it is very difficult to change these specific constants post-launch.
    • [ ] Benchmark any custom runtime functions - use benchmark values of existing runtime functions to specify accurate weights for your custom functions.
    • [x] "Canary Net"s and public testnets are pretty critical to having networks with realistic/real state/value to better test things like migrations and the economics of your network - if it is not already in the plans, consider building and maintaining at least one.

    Launch Checklist

    • [x] Are your genesis validators online and available? Do you have communication lines open to any third-party validators?
    • [x] Consider having a private "dry run" where you execute the public chainspec unreleased on your own infrastructure.

    Ops, Infrastructure, and Maintenance

    • [x] What is your CI infrastructure like for node or runtime upgrades? Can you release a critical upgrade within a single era as determined in your chainspec, and have validators upgrade?

    Upgrades and Future-proofing

    • [ ] What is your process for runtime upgrades? Are you familiar with using srtool (or equivalent) for deterministic builds? Users will need to verify runtime upgrades as well - you will need a process for communicating upgrades with them.
    • [x] For any upstream Substrate update: are you educated on exactly how this update may change your runtime, where the migration code is, if any, and any other breaking changes or changes in behavior it may present?
    • [x] For any runtime upgrade that changes storage format: have you written migration code (for your own pallets) and determined how to safely perform the upgrade on your network?
    • [x] Sanity Check: verify that any linked data in your runtime is migrated in an order/manner that does not break links.
    • [x] For all runtime upgrades: have you already tested out the runtime upgrades and any relevant migrations on a local or public testnet?
    • [x] Have you tested the latest version of the upgrade, including "minor last-minute changes"?

    • [x] Darwinia dev-net.

  • Crab grandpa finality issues

    Crab grandpa finality issues

    In v0.5.0 devnet testing, the finalized block stall on zero. Here is some analysis about the case:

    Reproduce the steps:

    1. There are 4 validators configed in genesis session with session keys, including grandpa key(ed25519), two of them get online intime with right keys before the on_session_change, but the other two didn't. Because there are only 2/4 (< 2/3) validators gossiping the grandpa, so the blocks in genesis didn't get finalized.

    2. After several session, other validators start bond and start validating, and the grandpa authorities set get changed, even though there might be > 2/3 validators online now, the blocks in later session didn't get finalized because there are previous blocks(those in the genesis session) remain unfinalized.

    Notice the assumption here: Blocks in one session must be finalized by the grandpa keys set of that session, cannot finalized by the keys set in latest session, this assumption need to be confirmed. Because in p2p networks, you cannot make sure what happens to the other offline branch and its successor key sets which could be different. The branches might just fork due to network connections and can not see each other, from decentralized perspective, you can not determine which branch should get finalized.

    For the case in crab v0.5.0 devnet, the two genesis offline validators start validating later, but used different grandpa keys by setting rotate_keys using rpc call. Although they have same validator id with genesis config, but because the grandpa key has changed, so I guess that changed grandpa key will not work to help reach finality consensus for genesis session blocks.

    Maybe we can make a experiment by requesting the two offline validator to change their grandpa keys back to the keys in genesis config and see whether it will helps?

    Currently, substrate lacks diagnostic methods except -lafg option, but some works is already in progress to help improve this.
