An application that allows a user to explore the different blocks on a blockchain.
A node that maintains a parachain by collecting parachain transactions and producing state transition proofs for the validators.
Collators and nominators get paid from block production on the network, where collators can set a variable commission rate, which is initially subtracted from the total rewards that collator is entitled to (for that period), where the commission determines the rate of distribution for the remaining rewards set out for the nominators that are backing that collator.
A generic term for a decentralized application, that is, one that runs as part of a distributed network as opposed to being run on a specific system or set of systems.
An epoch is a time duration in the BABE protocol that is broken into smaller time slots. Each slot has at least one slot leader who has the right to propose a block. In Kusama, it is the same duration as a session.
A (whole) number of sessions, which is the period that the validator set (and each validator's active nominator set) is recalculated and where rewards are paid out.
A blockchain that meets several characteristics that allow it to work within the confines of the Polkadot Host. Also known as "parallelized chain.”
Users participate in staking, and the rights and interests obtained by bonding RING or KTON are called power.
Power share is the percentage of Power held in total Power. The greater the power share, the greater the influence of the decision made on the entire chain.
