Ecosystem
The ecosystem layer in Casper encompasses dApp design and operation.
Entry point
See EntryPoint and Defining the Contract Entry Points.
Equivocation
A process where dishonest nodes sign conflicting consensus messages. If a node is caught equivocating, other validators will ignore its messages, and the node will become inactive.
Era
A period of time during which the validator set does not change.
In a Casper network, validators cannot join and leave at any point in time, but only at era boundaries. An era's validators are determined using an auction. At the beginning of the era, the validators create a new instance of the consensus protocol and run this instance until they finalize the era's last block (see booking block).
Eviction
Validators that fail to participate in era will have their bid deactivated by the protocol, suspending their participation until they signal readiness to resume participation by invoking a method in the auction contract.
External client
Any hardware/software connecting to a Node for the purpose of sending transactions or querying the state of the blockchain.
