Staking and yield: key words
Read the word, say the meaning out loud, then open the card.
Yield
What an investment earns over a year, shown as a percentage of the amount put in. Source
Staking
Locking up a proof-of-stake network's coins so that they can be used to help run the network, in return for rewards. Source
Issuance
Creating new coins that did not exist before. On proof-of-stake networks, new coins are paid to validators as rewards. Source
MEV (maximal extractable value)
Extra value a block producer can take by choosing which transactions go into a block, and in what order. Source
Slashing
The penalty for provable cheating by a validator: part of its stake is destroyed and it is forced out of the network. Source
Inactivity leak
An Ethereum emergency rule that slowly drains the stake of offline validators until the active ones hold more than two-thirds of it. Source
Exit queue
The rate-limited wait to stop staking. How long it takes depends on how many others are leaving at the same time. Source
Withdrawal address
The address a validator's staked ETH and rewards are sent to. On Ethereum it can be set only once. Source
Staking as a service
Delegated staking: you deposit your own 32 ETH, and a third-party operator runs the validator for a fee. Source
Liquid staking token (LST)
A receipt token for coins staked through a pool, which can be traded or used while the coins stay staked. Source
Rebasing token
A token whose balance in your wallet changes as rewards, or losses, are added. Lido's stETH is one. Source
Restaking
Using coins that are already staked to help secure other services too, for extra rewards and extra risks. Source
Actively Validated Service (AVS)
A service, such as a price oracle or a bridge, that is secured by restaked ETH and pays rewards for it. Source
APR (annual percentage rate)
A yearly rate that does not include the effect of compounding. Source
APY (annual percentage yield)
A yearly rate that includes the effect of compounding, worked out over a 365-day year. Source
Token dilution
When new tokens are created, each existing token becomes a smaller share of the total supply. Source
