Glossary: Nonce
A nonce is a random number miners change repeatedly while hashing to find a valid block hash below the target difficulty.
Makar
Glossary: Difficulty Adjustment
The automatic process that changes mining difficulty to keep block times consistent as network hashrate changes.
Glossary: Block Height
Block height is the position number of a block in the blockchain, counting from the first block ever created.
Glossary: Block Time
Block time is the average amount of time it takes for miners to find a new block and add it to the blockchain.
Glossary: Merkle Root
A single hash that represents all transactions in a block, created by combining transaction hashes in a tree structure.
Glossary: Confirmation
A block confirmation occurs when a new block is added on top of the block containing your transaction, making it harder to reverse.
Glossary: Genesis Block
The first block ever mined in a blockchain, hardcoded into the software and serving as the foundation for all subsequent blocks.
Glossary: Mempool
The mempool is the waiting room for unconfirmed transactions before miners include them in a block and add them to the blockchain.
Glossary: Full Node
A full node is a computer that stores the complete blockchain and independently verifies all transactions and blocks without trusting anyone else.
Glossary: Peer-to-Peer (P2P)
A peer-to-peer network lets computers connect directly without a central server, which is how cryptocurrency blockchains operate.
