Consensus rules
The protocol rules that determine whether blockchain transactions and blocks are valid.
PLAIN-ENGLISH DEFINITION
In more detail
These are the checks that keep the ledger consistent: who can spend, what a valid block contains and how much new value may be created. Full nodes enforce them locally. A powerful miner or validator cannot make a rule-breaking block valid just by announcing it loudly.
IN THE WILD
How you might use it
A miner proposes a Bitcoin block that claims too much newly issued BTC. Nodes following the rules reject it.
