Jumpstart network #918

JesseAbram · 2024-06-28T17:38:09Z

Jumpstarts the network with a global key

Uses same pathways but hardsets global key to 0x000 address

HCastano

There's a couple more things I need to look at, in particular the use of the zero-address around the different calls

pallets/registry/src/lib.rs

+        })]
+        pub fn jump_start_network(origin: OriginFor<T>) -> DispatchResult {
+            let _who = ensure_signed(origin)?;
+            let network_account = H256::zero();


We may want to avoid the zero address here because it has a well-known private key.

I say may instead of must since I don't have a full idea of where this address is actually "used", or if it's more of just a placeholder.

should be easily fixed with a guard on register, good find

Ive had a quick look at this and it looks great. Since it is a step towards having a network parent key but not fully implemented, Im trying to figure out what exactly the scope of this PR is.

This is what i am getting, please correct if wrong:

This adds a 'parent' DKG for the network - but does not yet remove per-user DKG.
The registry pallet tracks whether a network parent key exists (Done), does not exist (Ready) or DKG is in progress (InProgress), but there are not yet restrictions on users signing or registering when the network parent key does not exist.
The network DKG is activated by submitting a jump_start_network extrinsic - but there are currently no restrictions as to who can submit this or how big the network should be (Jump Start network requirements #923).
The network can only be jump started if it is either not yet jump started, or jump starting has been in-progress for at least 50 blocks.
The network is considered successfully jump started on getting register confirmations from all but one of the TSS nodes who participated in the network DKG (i am not totally clear on this, and i feel like it should be 100%).
Signature requests for the parent key account will result in an error.

yes

The registry pallet tracks whether a network parent key exists (Done), does not exist (Ready) or DKG is in progress (InProgress), but there are not yet restrictions on users signing or registering when the network parent key does not exist.

also yes because we don't use it yet.....and as we move the registery flow to the new flow this, is where having a block before jumpstart should be addressed

The network DKG is activated by submitting a jump_start_network extrinsic - but there are currently no restrictions as to who can submit this or how big the network should be (Jump Start network requirements #923).

The network can only be jump started if it is either not yet jump started, or jump starting has been in-progress for at least 50 blocks.

The network is considered successfully jump started on getting register confirmations from all but one of the TSS nodes who participated in the network DKG (i am not totally clear on this, and i feel like it should be 100%).

No it is all of them...... If you are referring to this line https://github.com/entropyxyz/entropy-core/pull/918/files#diff-1e0acd338c23affee5840b8efb06bd46be87c49819841bdcf3ce804631a40b92R340 it is because the last confirmation sets it to done as if there were 4 out of 5 done, this one is the 5th

Signature requests for the parent key account will result in an error.

Getting close!

Couple things:

It's unclear to me why we need to substitute the parent verifying key in the KVDB with 0x00...
I'm still slightly worried about the use of the zero address here, but we could kick this down the road to at least get things moving (maybe we open an issue for right now)
We need to rename comments, errors, etc. to parent

+            );


I think this could be useful to have. E.g we can have the Entropy network control an account on other chains like this.

Obvs this wouldn't work if the parent key address is the zero-address though.

In theory we don't and we can change it, but when we keep it a set amount, we can and it is easier to make it a global constant and have if parent key do x code easier (which we can also add extra security on it too)

I'm still slightly worried about the use of the zero address here, but we could kick this down the road to at least get things moving (maybe we open an issue for right now)

Global constant, I know your impulse, I think it is fine we can make it any random key tbh

We need to rename comments, errors, etc. to parent

HCastano

Few things we need to follow up on, but looks good otherwise!

            data.block_number,
        )
        .await?;
        let verifying_key = key_share.verifying_key().to_encoded_point(true).as_bytes().to_vec();
-        let string_verifying_key = hex::encode(verifying_key.clone()).to_string();
+        let string_verifying_key = if sig_request_account == NETWORK_PARENT_KEY.encode() {
+            hex::encode(*NETWORK_PARENT_KEY)


One suggestion: instead of overwriting the parent's verifying key to be 0x00 we could
have a separate "forbidden key" entry, PARENT_VERIFYING_KEY, which points to the parent
verifying key.

For those checks you mention, we could achieve them the same way, but doing an extra
lookup.

That way we keep the verifying key entries consistent.

sure at this point tho im in favour of opening an issue

Yeah an issue is fine
