+description: Comparing restaking to Polkadot's native economic security.
+keywords: [ethereum, Ethereum, eigenlayer]
+slug: ../learn-comparisons-restaking
+---
+
+This comparison aims to compare the notion of **restaking**, an up-and-coming way to secure
+decentralized layers built on top of Ethereum, to Polkadot's native economic security. EigenLayer
+will be the primary subject of comparison to Polkadot, as its goals are similar.
+
+## A Quick Summary: Restaking
+
+Restaking's primary focus access to provide **pooled security**, where something like EigenLayer
+will provide cryptoeconomic security for whoever builds on them. Through a series of derived assets,
+backed by pools of staked ETH, different layers and dApps built using EigenLayer will have the
+advantage of economic security without having to create and manage their own token. Effectively,
+this solves the **bootstrap problem** that most new protocols face in the blockchain space.
+
+:::info What is the bootstrap problem?
+
+The bootstrap problem refers to the initial challenge most new protocols face: economic security.
+When a new decentralized protocol is created, it often requires some unit of exchange (usually in
+the form of a token) to deter adversaries from attempting to attack, as the cost of attacking the
+protocol outweighs any potential gain.
+
+Creating and managing a new token comes with a set of challenges - both technical and legal, which
+is why having an available pool of economic security is appealing to new protocols.
+
+:::

+a["Stake(ETH)"] --> b["Recieve(sETH)"] --> c["Restake(sETH)"] --> d["Service X"]
+```
+
+Where staking ETH secures Ethereum, restaking using a protocol like EigenLayer will allow a user to
+allocate some amount of economic security to some Service X, which could be a bridge, layer two
+system, or other (decentralized) layer that requires economic security.
+
+### Restaking vs. Liquid Staking
+
+Liquid Staking preserve liquidity through an LP token (liquidity provider). This LP token is
+exchangeable one-to-one to the native token, but is usable for DeFi purposes (usually in a
+decentralized exchange, or DEX).
+
+The conversion for liquid staking can only occur once. For example,a user may stake 10 DOT natively,
+and the liquid staking protocol returns 10 lpDOT in return. The 10 lpDOT can be used while my 10 DOT
+is staked.
+
+Restaking can occur twice - firstly with staked ETH, for example, then secondly to whichever service
+it chooses to secure.
+
+## A Quick Summary: Polkadot Economic Security (NPoS)
+
+Polkadot's economic security is native to its protocol. Through NPoS, a series of nominators and
+validators ensure the honest allocation of staked tokens and smooth propagation of any network state
+transitions. This includes the security and availability of any parachains that have a registered
+slot on Polkadot.
+
+```mermaid
+flowchart LR
+a["Stake(DOT)"] --> b["Secure X Services"]
+```
+
+Polkadot also has a series of secondary availability and validity checks on candidate blocks before
+going through the finality process with [GRANDPA](../general/glossary.md#grandpa-finality-gadget).
+These checks contribute in ensuring that validators are behaving, and are slashed accordingly.
