What Is Liquid Staking?

Staking is the process of committing resources to a cause or investment while retaining ownership and the potential for gains or losses. In traditional finance, it often means investing with an expectation of rewards, balancing risk against potential returns.

 

However, blockchain technology has revolutionized these concepts. Decentralized finance (DeFi) has redefined traditional roles like lending and third-party involvement, with staking at the forefront of this transformation.

 

Liquid staking, a recent innovation in the blockchain sphere, offers a nuanced evolution of staking principles, enhancing security and utility. This article delves into liquid staking, a groundbreaking approach that combines the benefits of staking with improved liquidity and flexibility.

 

Proof Of Stake

The origins of staking lie in a key innovation in blockchain architecture — the proof-of-stake consensus mechanism.

 

The consensus mechanism of a blockchain is the system that determines which network participant gets the privilege of adding a block of new data to the permanent chain. A proof-of-work blockchain, such as bitcoin, bestows this privilege on the winner of a computational competition.

 

This blockchain secures the network by computing power; an opponent attempting to successfully attack such a network (“Bitcoin is backed by the largest computer network in the world, a network orders of magnitude larger than the combined size of the clouds that Amazon, Google, and Microsoft have built over the last 15–20 years.

 

In a sufficiently large network, such as bitcoin, having access to this many computational resources has now proven to be a de facto impossibility. And a “successful” attack only lasts for about 10 minutes: so per game theory, the would-be attacker simply counts the cost in advance of sustaining such an attack, and quickly learns that their resources would be better exhausted by simply buying more bitcoin.

 

Despite the extreme security of a proof-of-work blockchain, this mechanism makes the network inefficient in terms of both energy and output. It requires constantly running an enormous number of computers to secure the network. Proof of stake seeks to address these concerns.

 

A proof-of-stake blockchain hands out the privilege of adding a block at random to a small group of investors who have committed enough money to support the network. The far fewer participants needed means the network is substantially more efficient than proof-of-work chains.

 

Participants in a proof-of-stake blockchain commit value to the network by staking the blockchain’s native token. Staking tokens means locking them up in the network so they can’t be used for a set period of time; i.e., investor funds are not typically considered liquid, once staked.

 

A proof-of-stake chain is secured by the fact that attacking the network would require owning over 51% of all the staked coins. For a sufficiently large blockchain, this would not only be impractically expensive but also destroy the value of the staked tokens, thereby ruining the financial motive for attacking the network in the first place.

 

Why Stake?

To function, proof-of-stake networks need to convince users to stake their tokens, but users hesitate to do so because of the risks inherent in illiquidity.

 

Liquidity is the ability to use your assets, it’s the availability of capital to the market. Something is illiquid when it is not exchangeable; low liquidity means something is difficult to exchange, and high liquidity means something easy to exchange. Consider the differences between buried treasure, a house, and stone-cold cash.

 

When you stake your assets, you give up liquidity by locking the tokens, essentially burying them in the network for a set contracted time. This comes with certain risks that disincentivize participation in the network.

 

Since these tokens are locked, they can’t be sold in the sudden advent of a substantial price drop, meaning they could be worth far less when later unlocked. Additionally, they can’t be removed if a participant needs their money back, or the network is somehow compromised.

 

Proof-of-stake chains do not themselves mitigate this risk, but rather they pay users for taking it. The network acts similarly to how old-school bank savings accounts were designed. Today, proof-of-stake chains reward participants staking by paying a percentage back to the holder based on the size of their stake, which allows holders to earn true passive income on their holdings.

 

The Liquid Staking Revolution

But what if tokens could be staked and receive rewards without making the holder illiquid? It might sound contradictory, but this is the idea behind liquid staking. Liquid staking allows stak
