+Big-endian
+A positional number representation where the most significant digit is first in memory. The opposite of little-endian, where the least significant digit is first.
+Block
+A block is where transactions or digital actions are stored. Once a block is full, it gets linked to the previous one, creating a chain of blocks or a "blockchain". More on blocks.
+
+A block is a bundled unit of information that includes an ordered list of transactions and consensus-related information. Blocks are proposed by proof-of-stake validators, at which point they are shared across the entire peer-to-peer network, where they can easily be independently verified by all other nodes. Consensus rules govern what contents of a block are considered valid, and any invalid blocks are disregarded by the network. The ordering of these blocks and the transactions therein create a deterministic chain of events with the end representing the current state of the network.
+Block explorer
+An interface that allows a user to search for information from, and about, a blockchain. This includes retrieving individual transactions, activity associated with specific addresses and information about the network.
+Block header
+The block header is a collection of metadata about a block and a summary of the transactions included in the execution payload.
+Block propagation
+The process of transmitting a confirmed block to all other nodes in the network.
+Block proposer
+The specific validator chosen to create a block in a particular slot.
+Block reward
+The amount of ether rewarded to the proposer of a new valid block.
+Block status
+The states that a block can exist in. The possible states include:
+proposed: the block was proposed by a validator
+scheduled: validators are currently submitting data
+missed/skipped: the proposer did not propose a block within the eligible time frame
+orphaned: the block was reorg'd out by the fork choice algorithm
