Account
A kind of basic object in distributed ledger used to keep the balance and other information of users.
Address
A label consists of string of letters and numbers that anonymously represents user's identity on chain. Crypto assets can be sent to and/or from addresses. CKB address packages Lock Script into a single line, verifiable, and human read friendly format. A single public-private key pair can generate multiple Lock Scripts, consequently multiple addresses.

Asset
A piece of data that has value or that represents an entity having value.
Synonyms
Block
A grouping of transactions, marked with a timestamp, and a fingerprint of the previous block. The block header is hashed to produce a proof of work, thereby validating the transactions. Valid blocks are added to the main blockchain by network consensus.

Block Height
Block height is the total number of blocks that have been confirmed on the blockchain, also used to identify a unique block when specifying a particular block height, as there is always an exact block at any block height.

Block Interval
Also known as Block Time. Block interval is the length of time it takes to create a new block in a cryptocurrency blockchain. Block interval is the measure of the time it takes the miners or validators within a network to verify transactions within one block and produce a new block in that blockchain. The block interval is variable on Nervos blockchain.
The block interval on the Bitcoin blockchain is approximately every 10 minutes. The block interval on Nervos is variable, but is usually under 10 seconds.

Block Propagation
The process of synchronizing a new block to the majority of full nodes in the network. Block propagation is a well-known bottleneck that prevents Bitcoin from scaling.
Block propagation time is an average time that is needed for the new block to reach the majority of nodes in the network. Long block propagation delay reduces the node's resistance against 51% attacks.

Block Reward
The amount of cryptocurrency credited to a miner's account after the miner successfully adds a block of transactions to the blockchain.
In Nervos CKB, block rewards are the CKBytes credited to a miner's account after a block is successfully added to CKB by the miner.
See Also
Block Time
Alternatively referred to as Block Interval.
Synonyms
Blockchain
A data structure maintaining a growing list of records, organized as a chain of blocks. Each block, apart from the first one, is cryptographically linked to the previous block, thus creating a chain-like structure.
The cryptographic link ensures any party with the last block can verify that none of the historical data is modified after the creation of this block.
See Also
BLS Signature
A cryptographic signature scheme for signing and verification. BLS is short for Boneh–Lynn–Shacham.
See Also
Broadcast
Blocks are sent to all nodes in a blockchain network.

Capacity
The maximum space (in bytes) that a Cell can occupy on the Nervos CKB.
