Discussion on Node Operator Admission Criteria and Process

Hi all,

I wanted to open this thread to kickstart the discussion on the process of adding node operators to the Lido DAO.

As most of you know, node operators are at the heart of Lido; since earnings and slashing losses are socialized across all stETH holders, node operators need to be trusted and experienced entities that are able to run validating nodes of the highest possible quality in terms of security, availability, and reliability. I suggest to use this thread to start discussing the selection criteria and validator key distribution process for node operators.


Decentralize Lido further by adding best-in-class node operators with secure and reliable setups. This should lower the risk to stETH holders through diversification and introducing uncorrelated setups, which is especially important in light of Eth2’s anti-correlation penalties.

Suggested Criteria

  1. Dedicated team/company that can respond to potential incidents 24/7.
  2. Experience in operating staking infrastructure.
  • To evaluate this, a proxy like AUM (staked assets in $) could be used: e.g. at least $25m in assets staked.
  • Another proxy could be how long the team has been operating node infrastructure. We could e.g. say the team needs to have operated nodes for at least 2 years.
  1. Experience in operating Ethereum validators.
  • We could require proving that new node operators have already been running Ethereum validators without incidents for some timeframe.
  1. Other factors:
  • It will be desirable to add node operators that provide additional value to the DAO, e.g. in terms of developing helpful tools, helping with business development and marketing, etc. These factors should be covered in applications for LDO holders to consider for voting on new operators.

Discussion on # of node operators and approach to distributing keys

There’s also a need for a wider discussion on how many node operating entities the DAO needs and how to distribute keys among them. As of now, we seem to gravitate towards all initial node operators controlling the same amount of keys. I think we need to establish a more sophisticated process/mechanisms for deciding how to distribute “voting power” across node operating entities going forward. Clearly, new node operators should first get trialed with fewer amount of keys and then be “promoted” over time. I think it could be interesting to introduce some kind of tiered system, e.g. have newcomer operators with an initial limited amount of keys, then some further levels throughout which limits increase (i.e. established operators, core operators,…). There could be infrequent LDO votings to determine the distribution among those tiers. This is just an initial idea that needs further thought.

Curious to hear what other people think should be the evaluation criteria and mechanism for distributing keys. I think Lido has a unique opportunity to build one of the strongest and most resilient validator sets in crypto and we are excited by the promise of this!

There are a few topics tied to this one:

  1. when Lido should start to board new validators?
  2. as per @JK_stakefish post - how do we ensure alignment of the new operators?

For 1. I think there should be a couple of criteria crossed: first, a threshold of total staked eth % for each node operator of Lido: 0.5% of total ether staked per Lido operator (I think that’s the case already)? 1%?
The other is sustainability. Ops should be comfortably sustainable for an operator. ATM an operator earn from ~$400 to ~$1000 per month, which is not enough to pay hardware and labor costs for quality ethereum ops. When more validators come online, this will grow to 5-10x of this which feels like good enough. I think we’ll be able to cross the sustainability threshold in 2-3 weeks.

Overall, I think we’ll be ready to onboard a new operator in 2-3 weeks from now and the next one, depending on the stETH supply growth, pretty soon after that; by then we should have a simple process to determine that we have an open slot.

For 2. I’ll defer to the main distribution discussion for now.

Excellent points made, I especially like the point @JK_stakefish brings up in his linked post.

Regarding 1), I think we should start figuring out a process for this ASAP, especially as I expect there to be more interest in becoming a node operator than slots available. As JK puts it, we want “top tier validators” and this shouldn’t be decided by whoever can rush to a vote quickest.

I like the idea of a tiered approach, though lower tiers would probably not be profitable and this could raise issues. So it is probably better to start with 1-2 reputable operators and get them to a sizeable amount of validators quickly.

Would be helpful to see applicants provide data on their node performance, as it’s pretty hard to trust a new provider with community funds with no tangible proof of competency. We might want to clarify this in the application form to ensure best node providers can surface because a lot of applicants are pushing forward vague setups or architecture which show more knowledge of cloud computing than node running (even though the former is definitely helpful).

I second this, however this puts a barrier to entry to potentially good ETH node providers in terms of capital requirement.

That said, there are many protocols with lower (or null) capital requirements on which they can cut their teeth and gather performance data to show, circling back to the point above.

Should we suggest node providers get more node providing experience if we turn them down to ensure a supply of higher quality applications and node providers down the line?

In the end the supply of node providers won’t be infinite so we might as well help those who come to see Lido improve for the future rounds, making sure they understand we expect improvements.

Tailored feedback would probably require too much time given the application volume but some guidelines to share could be considered.

We can also think that all of the information about what makes a great node provider is out here in the open on the forum and that node providers who are able to find it and improve the quality of their application are also demonstrating a willingness to contribute to the community by taking a deep look at the forum while preparing their application, so we wouldn’t need to push the information to applicants as the motivated ones will find it anyway.

would love @Izzy thoughts on this as you’re looking closely at the process
