Security Deposit

A security deposit is the collateral provided by a validator to participate in the consensus process. This deposit is locked within the protocol and serves as a guarantee of honest behavior.

If the validator violates protocol rules, such as by double signing, the deposit is subject to being slashed. This creates an economic bond between the validator's actions and their financial capital.

The size of the deposit is often a factor in determining the validator's weight in the consensus process. It ensures that those with the most influence over the network also have the most to lose if the network is compromised.

The security deposit is a central element of the economic security of Proof of Stake blockchains. It transforms trust from a social or legal contract into an automated, verifiable economic constraint.

For investors and delegators, the security deposit provides a layer of assurance that the validator is incentivized to act correctly. It is a critical concept for understanding how trust is engineered in decentralized systems.
