Restaking describes the process that allows users to obtain additional network security through their existing staked assets. Users of proof of stake systems lock their tokens to validate network operations which results in the users receiving extra rewards for their efforts.
Users of traditional staking systems give their tokens to validators who use them to protect blockchain networks. The system provides them with staking rewards. Restaking builds on this structure by enabling those staked tokens, or the rights associated with them, to also secure other decentralized services. Organizations can use data availability layers, oracle networks, or other blockchain protocols to establish their operational framework.
Restaking aims to enhance capital efficiency for financial operations. The participants who take this approach can earn additional rewards because they provide security across multiple systems while their tokens remain unlocked. The system will bring more liquidity into the space while it provides growth support for new protocols which require financial support.
The process of restaking creates new risk elements which did not previously exist. Slashing penalties will apply to staked assets when a validator executes improper actions or when one of the linked services experiences downtime. The presence of multiple layers which use the same collateral results in compounded risk. Critics argue that this might create systemic risk because interconnected services will experience stress simultaneously.

The Ethereum development community has started to discuss restaking because new infrastructure projects need shared security systems. The crypto reporting field uses the term to describe staking innovation and protocol expansion and security framework development. People who understand restaking will discover through this knowledge how blockchain networks test new methods for distributing capital between risk and reward.
