Key Points
Ryan Berckmans, an experienced investor and engineer in the Ethereum ecosystem, has recently called on the community to address a potential crisis.
He has warned of a potential catastrophic failure within the Ethereum network if the upcoming Pectra hard fork does not include the Ethereum Improvement Proposal (EIP) 7251, also known as “maxeb.”
This proposal is aimed at mitigating a critical vulnerability in the network’s capacity to handle an increasing number of staked ETH by allowing for greater consolidation of validators.
The Potential Catastrophe for Ethereum
Berckmans expressed his concerns on X (formerly Twitter).
He stated that the Pectra hard fork should include EIP-7251.
Without it, Ethereum may not have a realistic defense against the possibility of staked ETH % growing to ~50%+ before a future ~2026 hard fork after Pectra.
He emphasized the severity of the situation by outlining the potential consequences of inaction, which could be disastrous for Ethereum.
EIP-7251 proposes an increase in the maximum effective balance for validators.
The current limit is 32 ETH, but the proposal suggests an unlimited amount.
This adjustment is meant to mitigate the risks associated with an overly fragmented validator pool, which could compromise the beacon chain’s stability.
Berckmans explained the technical challenges facing the network.
He stated that if staked ETH grows to ~50%+, that could result in severe-to-fatal beacon chain instability.
He noted that the network was not designed for such a large number of validators.
He also discussed the impracticality of modifying the beacon chain within the timeframe of the Pectra hard fork to support a higher percentage of staked ETH.
He stated that fixing the beacon chain to natively support 50%+ staked ETH is impossible for Pectra.
A longer-term solution is still in the research phase.
The Implications of “Maxeb”
The proposal is not just a temporary measure but a strategic enhancement to reduce the number of validators.
This is done without compromising the network’s decentralized ethos or altering its monetary policy.
Berckmans emphasized that EIP-7251 maxeb is more or less ready to go and achieves this goal of reducing the number of validators without being a monetary policy or issuance change.
He dismissed concerns that EIP-7251 might disproportionately benefit large staking operators or alter the network’s reward structure.
He stated that maxeb does not change issuance or staking rewards, is not a monetary policy change, and does not help the ‘rich get richer’.
Additionally, Berckmans highlighted the operational benefits that maxeb offers, especially for staking operators who currently manage multiple validators.
He noted that maxeb automatically, passively reinvests staking rewards, removing the need to make new transactions to stake every 32 ETH of rewards.
He also stated that maxeb can reduce devops costs and complexity for staking operators by letting them run one validator instead of dozens or tens of thousands of validators.
He concluded with a call to action, emphasizing the critical nature of this decision for Ethereum’s future.
He warned that if we don’t include maxeb in Pectra, we might be faced with a potentially disastrous situation in which we have to choose between the beacon chain falling over (Ethereum breaks) or making an emergency large change to monetary policy (heavily reducing staking rewards) to shrink the number of validators.
Despite the technical rationale behind EIP-7251, the proposal has received critical reactions from the broader crypto community, particularly among Bitcoin supporters.
Checkmatey, Glassnode’s Lead On-chain Analyst, offered a critical view, remarking that it is alarming when a proof-of-stake network is designed such that it becomes unstable when too many people stake.
At press time, ETH traded at $3,770.
