Ethereum’s powerful recent “EigenLayer” guarantees a wave of innovation. But is it a threat to the blockchain?

EigenLayer is a brand new protocol, or set of instructions, that sits on top of Ethereum’s foremost blockchain. It offers those that have already invested tokens through staking – a blockchain feature that rewards those that lock up their tokens to secure the network – the chance to re-stake those tokens. The term is what it feels like. Restaking involves users taking Ethereum tokens they’ve already invested after which re-investing them. But as a substitute of receiving a reward from the Ethereum network, as is the case with staking, those that do the restaking are paid by other projects that take part in the blockchain’s existing security pool.

Restaking has been around for a while, but EigenLayer is attempting to speed up the method by adding more participants. The protocol aspires to be something like an Amazon Web Services for cryptoeconomic security.

The implications of this are “profound,” a16z wrote in a blog post in regards to the company, noting that EigenLayer has the potential to speed up innovation on Ethereum “100x faster.” While this looks as if a promising development for the blockchain, EigenLayer has yet to be tested at scale. And while it may lead to a lift in innovation for Ethereum, some point to a serious potential downside: A brand new concentration of risk that, in a worst-case scenario, could harm each users and the broader blockchain ecosystem. Should Ethereum users view EigenLayer with excitement, fear, or each?

“Open a wormhole”

The introduction of EigenLayer is a boon each for investors, who can now more easily earn an extra portion of returns, and for developers, who can more quickly add a layer of trust in the shape of collateral. The problem, nonetheless, is that using the identical collateral pool to secure multiple elements of the blockchain creates recent vulnerabilities.

“It opens a wormhole,” said Rushi Manche, co-founder of Ethereum Layer-2 Movement Labs AssetsSome brought up a troubling hypothesis recommend by EigenLayer critics: What happens if there may be a hack or a bug within the restaking smart contract? How does that affect the broader ecosystem that also relies on that single deposit?

At the identical time, some noted that proponents say that because of EigenLayer, “a whole new design space has opened up for developers,” allowing the identical asset to be prolonged much further and achieved far more. From this angle, the advantages far outweigh the risks. It’s also value considering the downsides of not having tools like EigenLayer available.

Notably, within the absence of restaking, decentralized applications built on Ethereum can have to create their very own proof-of-stake token—a high hurdle for any startup. Restaking allows protocols to tap into the foremost blockchain’s nearly $95 billion in staked Ether for security. Going back to the cloud computing analogy, if hackers need to attack small businesses, they should get past Google Cloud or AWS, which those businesses depend on. EigenLayer’s proponents argue the identical thing: hackers must get past a security system developed by Ethereum, whose market cap is greater than 3 times that of Nike.

But what happens if the identical collateral is used time and again?

“EigenLayer reminds me of the 2008 recession: too little collateral, too much debt. It will be fine,” said one X user Posted— just one in every of many industry observers who drawn Parallels to the financial crash, by which banks repledged subprime mortgage loans.

Austin Campbell, former head of portfolio management at Paxos, said Assets that the comparison shouldn’t be trivial. “At the heart of any leverage system lies the simple truth that the more leverage you use, the more unstable the system is,” he said.

There is a risk of a “cascade of failures” if a project fails, agrees Omid Malekan, an associate professor at Columbia Business School. But he and plenty of experts were also quick to nuance the 2008 parallels: Restaking shouldn’t be about borrowing and lending over and another time. Rather, it involves taking a locked asset and locking it up again. Think of it more like reusing the safety deposit on an apartment to secure more apartments, suggests Jack O’Holleran, CEO of Skale, an Ethereum Layer-2.

But what happens should you trash each apartments?

One scenario of so-called apartment trashing can be if the operators of the restaking services – often known as AVS for “Actively Validately Services” – decided to devalue the tokens that were re-staked. “It could be this ‘house of cards’ effect, but in reverse,” says O’Holleran.

The debate is analogous to criticism of liquid staking provider Lido, which currently accounts for 28% of all Ethereum staked. In theory, Lido introduces a “centralized point of failure” that’s “obviously concerning,” said Tekin Salimi, founding father of dao5 Capital and seed investor at EigenLater AssetsBut in his view, the answer shouldn’t be to stop this innovation, but to diversify liquid staking providers.

EigenLayer acknowledges these concerns, explaining on its website that it has a “veto committee” to curb slashing – the term utilized in the Ethereum world for destroying the collateral of validators who fail to satisfy their obligations – and forestall contagion of the mainnet or other protocols. It will function a “dual-trusted intermediary between AVS and stakers.” So slashing conditions are on the discretion of every AVS, not the general protocol. How that may work in practice, nonetheless, is unclear. In that sense, slashing risks remain “the most real yet undefined” of all of the risks raised, says Vance Spencer, co-founder of crypto enterprise capital firm Framework Ventures.

“Don’t overload the system,” warns Ethereum founder

EigenLayer has raised specific security concerns, but additionally a broader existential one: What proportion of staked tokens will be targeting a separate protocol on Ethereum, which sees decentralization as its highest value? According to O’Holleran, the empowerment of EigenLayer means the Ethereum community is giving significant influence and power to a different system. In addition, copycat restaking services are also popping up, resembling Karak, which announced a $48 million Series A funding round last month. In addition, an unnamed but similar version will launch soon, sources aware of the matter said. Assets.

Vitalik Buterin, the founding father of Ethereum, raised concerns about EigenLayer in a blog post last May. “Be wary of application-layer projects that take actions that might expand the ‘scope’ of blockchain consensus to anything other than verifying the core rules of the Ethereum protocol,” he wrote. Buterin warns of the “slippery slope” where the underlying network’s “fragile” social consensus loses credibility. His message was clear: Don’t overload the network’s consensus.

One of the concentration risks that worries Buterin most is the overloading of system security.

The strength of Ethereum’s security system is directly related to the economic value of the network – it will be prohibitively expensive for hackers to expend the resources to beat the consensus system that protects the network. “We agree that Ether is used to secure the mainnet, and that’s the sole purpose of it,” Campbell says. But should you use your staked tokens to secure Ethereum and other networks, then the surface area of ​​things that Ether is used to secure grows. So the worth resting on each individual point gets larger, Campbell explains, which could provide more attractive incentives for hackers.

The second concentration risk concerns decision-making. Let’s say 40% of Ethereum tokens are eventually re-staked and EigenLayer’s smart contract is hacked or bugged. It’s unclear when there can be consensus to reset Ethereum to release it, explains Tom Schmidt, partner at crypto enterprise capital firm Dragonfly. “I don’t know where that threshold is,” he admits.
