RFC-0117: The Unbrick Collective

-
- - - -
Start Date22 August 2024
DescriptionThe Unbrick Collective aims to help teams rescuing a para once it stops producing blocks
AuthorsBryan Chen, Pablo Dorado
-
-

Summary

-

A followup of the RFC-0014. This RFC proposes adding a new collective to the Polkadot Collectives -Chain: The Unbrick Collective, as well as improvements in the mechanisms that will allow teams -operating paras that had stopped producing blocks to be assisted, in order to restore the production -of blocks of these paras.

-

Motivation

-

Since the initial launch of Polkadot parachains, there has been many incidients causing parachains -to stop producing new blocks (therefore, being bricked) and many occurrences that requires -Polkadot governance to update the parachain head state/wasm. This can be due to many reasons range -from incorrectly registering the initial head state, inability to use sudo key, bad runtime -migration, bad weight configuration, and bugs in the development of the Polkadot SDK.

-

Currently, when the para is not unlocked in the paras registrar1, the Root origin is required to -perform such actions, involving the governance process to invoke this origin, which can be very -resource expensive for the teams. The long voting and enactment times also could result significant -damage to the parachain and users.

-

Finally, other instances of governance that might enact a call using the Root origin (like the -Polkadot Fellowship), due to the nature of their mission, are not fit to carry these kind of tasks.

-

In consequence, the idea of a Unbrick Collective that can provide assistance to para teams when -they brick and further protection against future halts is reasonable enough.

-

Stakeholders

- -

Explanation

-

The Collective

-

The Unbrick Collective is defined as an unranked collective of members, not paid by the Polkadot -Treasury. Its main goal is to serve as a point of contact and assistance for enacting the actions -needed to unbrick a para. Such actions are:

- -

In order to ensure these changes are safe enough for the network, actions enacted by the Unbrick -Collective must be whitelisted via similar mechanisms followed by collectives like the Polkadot -Fellowship. This will prevent unintended, not overseen changes on other paras to occur.

-

Also, teams might opt-in to delegate handling their para in the registry to the Collective. This -allows to perform similar actions using the paras registrar, allowing for a shorter path to unbrick a -para.

-

The Unbrick Process

-

-    A -- Bricked --> C[Request Unbrick «via governance»]
-    C --> D[unbrick call proposal on WhitelistedUnbrickCaller]
-    C --> E[whitelist call proposal on the Unbrick governance]
-    E -- call whitelisted --> F[unbrick call enacted]

-    O -- Bricked --> P[Collective calls registrar]
-    P --> Y
-    
-    Y[update PVF / head state] -- Unbricked --> Z[End]
-
-

Initially, a para team has two paths to handle a potential unbrick of their para in the case it -stops producing blocks.

-
    -
  1. Opt-in to the Unbrick Collective: This is done by delegating the handling of the para -in the paras registrar to the Collective. This doesn't require unlocking the para. This way, -the collective is enabled to perform changes in the paras registrar without the need for -whitelisting.
    2. -
  2. Request an Unbrick Process: In case the para hasn't delegated its handling in the paras -registrar, it'll be still possible for the para team to submit a proposal to unbrick the para, -assisted by the Collective. This process is expected to be more expedite (and less expensive) -for a team to perform than submitting a proposal on the Root governance track.
    3. -
-

Belonging to the Collective

-

The collective will be initially created without members (no seeding). There will be additional -governance proposals to setup the seed members.

-

The origins able to modify the members of the collective are:

- -

The members are responsible to verify the technical details of the unbrick requests (i.e. the hash -of the new PVF being set). Therefore, they must have the technical capacity to perform such tasks.

-

Suggested requirements to become a member are the following:

- -

Drawbacks

-

The ability to modify the Head State and/or the PVF of a para means a possibility to perform -arbitrary modifications of it (i.e. take control the native parachain token or any bridged assets -in the para).

-

This could introduce a new attack vectorm, and therefore, such great power needs to be handled -carefully.

-

Testing, Security, and Privacy

-

The implementation of this RFC will be tested on testnets (Rococo and Westend) first.

-

An audit will be required to ensure the implementation doesn't introduce unwanted side effects.

-

There are no privacy related concerns.

-

Performance, Ergonomics, and Compatibility

    The full nodes of the Polkadot peer-to-peer network maintain a distributed hash table (DHT), which is currently used for full nodes discovery and validators discovery purposes.

    Motivation

    The maintenance of bootnodes has long been an annoyance for everyone.

    When a bootnode is newly-deployed or removed, every chain specification must be updated in order to take the update into account. This has lead to various non-optimal solutions, such as pulling chain specifications from GitHub repositories. When it comes to RPC nodes, UX developers often have trouble finding up-to-date addresses of parachain RPC nodes. With the ongoing migration from RPC nodes to light clients, similar problems would happen with chain specifications as well.

    @@ -4847,9 +4682,9 @@ When it comes to RPC nodes, UX developers often have trouble finding up-to-date

    Because the list of bootnodes in chain specifications is so annoying to modify, the consequence is that the number of bootnodes is rather low (typically between 2 and 15). In order to better resist downtimes and DoS attacks, a better solution would be to use every node of a certain chain as potential bootnode, rather than special-casing some specific nodes.

    While this RFC doesn't solve these problems for relay chains, it aims at solving it for parachains by storing the list of all the full nodes of a parachain on the relay chain DHT.

    Assuming that this RFC is implemented, and that light clients are used, deploying a parachain wouldn't require more work than registering it onto the relay chain and starting the collators. There wouldn't be any need for special infrastructure nodes anymore.

    Explanation

    The content of this RFC only applies for parachains and parachain nodes that are "Substrate-compatible". It is in no way mandatory for parachains to comply to this RFC.

    Note that "Substrate-compatible" is very loosely defined as "implements the same mechanisms and networking protocols as Substrate". The author of this RFC believes that "Substrate-compatible" should be very precisely specified, but there is controversy on this topic.

    While a lot of this RFC concerns the implementation of parachain nodes, it makes use of the resources of the Polkadot chain, and as such it is important to describe them in the Polkadot specification.

    @@ -4886,10 +4721,10 @@ message Response {

    The maximum size of a response is set to an arbitrary 16kiB. The responding side should make sure to conform to this limit. Given that fork_id is typically very small and that the only variable-length field is addrs, this is easily achieved by limiting the number of addresses.

    Implementers should be aware that addrs might be very large, and are encouraged to limit the number of addrs to an implementation-defined value.

    -

    Drawbacks

    +

    Drawbacks

    The peer_id and addrs fields are in theory not strictly needed, as the PeerId and addresses could be always equal to the PeerId and addresses of the node being registered as the provider and serving the response. However, the Cumulus implementation currently uses two different networking stacks, one of the parachain and one for the relay chain, using two separate PeerIds and addresses, and as such the PeerId and addresses of the other networking stack must be indicated. Asking them to use only one networking stack wouldn't feasible in a realistic time frame.

    The values of the genesis_hash and fork_id fields cannot be verified by the requester and are expected to be unused at the moment. Instead, a client that desires connecting to a parachain is expected to obtain the genesis hash and fork ID of the parachain from the parachain chain specification. These fields are included in the networking protocol nonetheless in case an acceptable solution is found in the future, and in order to allow use cases such as discovering parachains in a not-strictly-trusted way.

    Because not all nodes want to be used as bootnodes, implementers are encouraged to provide a way to disable this mechanism. However, it is very much encouraged to leave this mechanism on by default for all parachain nodes.

    This mechanism doesn't add or remove any security by itself, as it relies on existing mechanisms. However, if the principle of chain specification bootnodes is entirely replaced with the mechanism described in this RFC (which is the objective), then it becomes important whether the mechanism in this RFC can be abused in order to make a parachain unreachable.

    For this reason, an attacker can abuse this mechanism by randomly generating libp2p PeerIds until they find the 20 entries closest to the key representing the target parachain. They are then in control of the parachain bootnodes. Because the key changes periodically and isn't predictable, and assuming that the Polkadot DHT is sufficiently large, it is not realistic for an attack like this to be maintained in the long term.

    Furthermore, parachain clients are expected to cache a list of known good nodes on their disk. If the mechanism described in this RFC went down, it would only prevent new nodes from accessing the parachain, while clients that have connected before would not be affected.

    Performance

    The DHT mechanism generally has a low overhead, especially given that publishing providers is done only every 24 hours.

    Doing a Kademlia iterative query then sending a provider record shouldn't take more than around 50 kiB in total of bandwidth for the parachain bootnode.

    Assuming 1000 parachain full nodes, the 20 Polkadot full nodes corresponding to a specific parachain will each receive a sudden spike of a few megabytes of networking traffic when the key rotates. Again, this is relatively negligible. If this becomes a problem, one can add a random delay before a parachain full node registers itself to be the provider of the key corresponding to BabeApi_next_epoch.

    Maybe the biggest uncertainty is the traffic that the 20 Polkadot full nodes will receive from light clients that desire knowing the bootnodes of a parachain. Light clients are generally encouraged to cache the peers that they use between restarts, so they should only query these 20 Polkadot full nodes at their first initialization. If this every becomes a problem, this value of 20 is an arbitrary constant that can be increased for more redundancy.

    It's in the interest of the Polkadot community to have a consistent and predictable Treasury income, because volatility in the inflow can be damaging, especially in situations when it is insufficient. As such, this RFC operates under the presumption of a steady and sustainable Treasury income flow, which is crucial for the Polkadot community's stability. The assurance of a predictable Treasury income, as outlined in a prior discussion here, or through other equally effective measures, serves as a baseline assumption for this argument.

    Consequently, we need not concern ourselves with this particular issue here. This naturally begs the question - why should we introduce additional volatility to the Treasury by aligning it with the variable Coretime sales? It's worth noting that Coretime revenues often exhibit an inverse relationship with periods when Treasury spending should ideally be ramped up. During periods of low Coretime utilization (indicated by lower revenue), Treasury should spend more on projects and endeavours to increase the demand for Coretime. This pattern underscores that Coretime sales, by their very nature, are an inconsistent and unpredictable source of funding for the Treasury. Given the importance of maintaining a steady and predictable inflow, it's unnecessary to rely on another volatile mechanism. Some might argue that we could have both: a steady inflow (from inflation) and some added bonus from Coretime sales, but burning the revenue would offer further benefits as described below.

    Summary

    Since the introduction of the Collectives parachain, many groups have expressed interest in forming new -- or migrating existing groups into -- on-chain collectives. While adding a new collective is relatively simple from a technical standpoint, the Fellowship will need to merge new pallets into the Collectives parachain for each new collective. This RFC proposes a means for the network to ratify a new collective, thus instructing the Fellowship to instate it in the runtime.

    Drawbacks

    Other than all other system chains, development and maintenance of the Encointer Network is mainly financed by the KSM Treasury and possibly the DOT Treasury in the future. Encointer is dedicated to maintaining its network and runtime code for as long as possible, but there is a dependency on funding which is not in the hands of the fellowship. The only risk in the context of funding, however, is that the Encointer runtime will see less frequent updates if there's less funding.

    Summary

    The Relay Chain contains most of the core logic for the Polkadot network. While this was necessary prior to the launch of parachains and development of XCM, most of this logic can exist in parachains. This is a proposal to migrate several subsystems into system parachains.

    Polkadot's scaling approach allows many distinct state machines (known generally as parachains) to operate with common guarantees about the validity and security of their state transitions. Polkadot provides these common guarantees by executing the state transitions on a strict subset (a backing @@ -6297,13 +6132,13 @@ blockspace) to the network.
