Name changes for GrandPa and Beefy notifications protocols #10463

acatangiu · 2021-12-10T12:05:05Z

polkadot companion: paritytech/polkadot#4519
cumulus companion: paritytech/cumulus#870

First commit still uses static protocol name, but removes paritytech.

Following commits add support for building dynamic protocol name using /<genesis-hash> prefix. /<fork-id> is also appended to the prefix if the chain has forked.

Introduces fork_id in the substrate ChainSpec definition.

Fixes #7252
Fixes paritytech/grandpa-bridge-gadget#240
Related to #7746

I think that the protocolId should not be re-purposed as a "hard fork identifier". We should instead introduce a new optional field in the chain spec and deprecate protocolId.

The reasons are:

We've written documentation and guides about this protocolId, and the new role of this hard fork identifier is different enough that it would just be confusing (example)
Most chains will never encounter any hard fork, and I don't see why you'd need to use both the genesis hash plus an arbitrary string, rather than just the genesis hash. So the default value for this new hard fork identifier should be None, meaning it's not used. And we would like all existing chains (assuming they're not a hard fork) to switch to a value of None rather than keep their existing protocolId.

A minor unrelated point is that I think it should be /<hash>/<id> and not /<id>/<hash>
It is possible to have multiple ids with the same hash, but (normally) never multiple hashes with the same id.

@tomaka were you thinking something like this: d4b616a ?

tomaka · 2021-12-13T12:29:05Z

Yes!

'fork_id' is used to uniquely identify forks of the same chain/network 'ChainSpec' trait provides default 'None' implementation, meaning this chain hasn't been forked.

Could you please not force push? 🙏 I was in the middle of reviewing and this ruins reviews in progress.

👍 This looks good to me from a networking perspective, but I don't know what others think of the changes in bin/* and in Grandpa & Beefy.

Anything parachain teams needs to be aware of about this? Will this cause any compatibility issues?
Looks like this only touches Grandpa/Beefy which only exists on relaychain so there should be no effect on parachain?
It does introduce a fork id but it should be fully backward compatible if we just leave it to none?

Nothing changes for parachains. You just use None for fork_id.

And the code is also backwards compatible for the relay chain.
