Lido has been at the forefront of Ethereum staking, offering a secure and efficient platform for users to stake their ETH and earn rewards. With the Lido V2 mainnet upgrade, the protocol takes a major step forward, addressing key challenges and paving the way for a more robust and decentralized ecosystem.

We’ve distilled everything you need to know about the upgrade - and why it’s so significant in the ETH staking ecosystem.

Lido V2 brings two vital components to the Lido protocol: withdrawals and the staking router.

  1. Withdrawals: Ethereum stakers on Lido can now easily convert and exit their stETH tokens back to ETH at a 1:1 ratio. This feature achieves a crucial milestone by providing an open on/off ramp into the Ethereum staking ecosystem. Users can unstake their ETH directly through the protocol, streamlining the process and making it more user-friendly.
  2. Staking Router: The new modular architectural design of the staking router allows for the inclusion of various types of Node Operators. This ranges from individual stakers to DAOs and Distributed Validator Technology (DVT) clusters. The staking router promotes a diverse and inclusive validator ecosystem, expanding opportunities for participation and further decentralization.


  • Enhanced User Experience: By introducing in-protocol ETH withdrawals, Lido V2 simplifies the staking process, providing users with more flexibility and control over their assets.
  • Protocol Decentralization: The staking router enables the inclusion of a broader range of Node Operators, fostering a more diverse validator ecosystem. This decentralization is essential for the long-term sustainability and security of the Ethereum network.

Impact on Ethereum Staking

The Lido V2 upgrade positively impacts the Ethereum staking landscape:

  • Increased Exposure: With the ability to unstake ETH through Lido, users have a seamless on/off ramp to participate in Ethereum staking, enhancing overall exposure to this growing ecosystem.
  • Streamlined Integration: The modular design of the staking router opens doors for various types of Node Operators, encouraging wider participation and creating opportunities for new stakeholders.

Following the successful on-chain vote and the launch of Lido V2 on the Ethereum mainnet, the market responded with enthusiasm. Following the announcement, the Lido DAO token (LDO) experienced a 10% price rally , reflecting the market's recognition of the significance of the upgrade and its potential impact on Ethereum staking.

Lido’s V2 mainnet marks a significant milestone for the Lido protocol and Ethereum staking as a whole. With the introduction of in-protocol ETH withdrawals and the innovative staking router, it empowers users, promotes decentralization, and strengthens the overall Ethereum ecosystem. As institutional interest in staking continues to grow, Lido's advancements align perfectly with this trend.

Key Takeaways: The Evolution of Shared Security
A digestable summary of the evolution of shared security and its various implemetation strategies
May 16, 2023
5 min read

The second chapter of our Q1 2023 Quarterly Insights comprehensively examines the evolution of shared security in PoS networks. It delves into the various strategies employed by different networks to implement shared security, shedding light on the incentives and risks involved. This article distills the key takeaways from our research, offering a succinct summary of the various approaches to shared security.

What is shared security?

Shared security is a form of improving the safety of a blockchain by using resources from other blockchains. It works similarly to merge mining in PoW networks, where miners use one blockchain to mine another.

To make this concept  work, there needs to be at least one blockchain providing security and another one using it. The system must allow for penalties if either blockchain misbehaves, usually by reducing their stake.

Use Cases

There are two key motivations behind the concept:

  1. To make it easier to launch new chains by using already secure and established chains as a foundation
  2. To allow people to participate in multiple PoS chains without having to deploy additional capital.

Different approaches to shared security


Rollups, or  ‘Layer 2s’ are shared security solutions that take execution off the main chain to scale computation and memory while keeping settlement on the Layer 1 chain.

Essentially, Rollups democratize execution by offering a fully compatible environment for easy application deployment and value transfer, but lower transaction cost. They guarantee security through smart contracts deployed on the Layer 1 to store transaction data, monitor state updates, and track user deposits.

There are two types of rollups: Optimistic and Zero-knowledge (ZK)

  • Otimistic Rollups: These are fraud proof based protocols that ensure that a state transition* is correct. There is a Dispute Time Delay (DTD) period during which a user can dispute an incorrect state. Optimistic rollups have two additional layers: the sequencer and validators. The sequencer sorts and commits transactions to the Layer 1 while validators run fraud proofs.
  • ZK rollups: By contrast, ZK rollups use validity proofs to verify state transitions.The operator submits transaction data to the Layer 1 and publishes the validity proofs that provide a cryptographic guarantee that the proposed state changes are true. ZK rollups have faster transaction finality than optimistic rollups.

*A State Transitions is a change in the overall state of the network, which can occur when a user sends a transaction that updates the state of their account or interacts with a smart contract that changes the state of the network.


EigenLayer is a protocol built on Ethereum that allows users who hold ETH or ETH liquid staking tokens to restake their tokens and earn additional rewards. Restaking involves users giving their tokens to a service, which uses the tokens to secure its own network and other networks.

However, by doing so, users take on the risk of being slashed if they act maliciously according to the rules set out in the service's slashing contract.

EigenLayer uses the slashing contract to determine whether a user has acted maliciously and to slash their tokens accordingly. The protocol is currently on testnet and has recently raised $50 million in a Series A funding round led by Blockchain Capital, with participation from Coinbase Ventures and Polychain Capital.

ICS: replicated and mesh security

Replicated security, a system that first went live on the Cosmos Hub in March 2023 as the initial version of the Interchain Security protocol (“ICS”), allows other Cosmos chains to apply to get the entire security of the Cosmos Hub validator set.

In other words, by participating in ICS, a consumer chain can leverage the security of the Cosmos Hub validator set to ensure that its own blockchain is secure. This is done by having the validators of the Cosmos Hub also run the code of the consumer chain, and being subject to slashing for any downtime or fraudulent behavior.

However, there are some challenges with this approach, such as scaling issues and the potential for poor performance if the validator set of a consumer chain secured by multiple providers grows too large.

To address these challenges, a new approach called Mesh Security was proposed by Sunny Aggarwal, the CEO of Osmosis. Mesh Security allows for delegators on the provider chains to re-delegate their tokens to validators on the consumer chain's own validator set, without any additional overhead. This means that operators who already run nodes for both the provider and consumer chain can be delegated more voting power on the consumer chain, resulting in an approach that is similar to what EigenLayer is proposing for Ethereum.


Babylon is a project that aims to improve the security of Cosmos zones and other PoS chains by using the security of Bitcoin. It is made up of three components:

  1. Bitcoin, which serves as a timestamping service.
  2. The Babylon chain, which is a Cosmos zone that acts as the middle layer.
  3. Other Cosmos zones, which are the consumers of security.

Babylon operates by receiving streams of transaction data checkpoints from multiple PoS chains and then combines these checkpoints into a single stream which is posted to Bitcoin. To achieve this, it uses the IBC (Inter-Blockchain Communication) protocol to trigger a transaction sent to the miners. This transaction is added to the Bitcoin ledger, effectively timestamping the events occurring in other blockchains through a process known as ‘checkpointing’.  

Currently, Babylon is on testnet, and 13 Cosmos zones are experimenting with it.

Overall, shared security aims to improve decentralization of applications and increase the cost of corruption of lower value networks. However, despite its advantages, shared security also carries inherent risks. It can compromise decentralization, opening doors to higher levels of contagiousness during stress scenarios.  Additionally, it may introduce risks to smart contract implementations, as users may lose their tokens due to factors outside of the base protocol layer.
