The first widely adopted decentralized cryptocurrency, introduced as a peer-to-peer electronic cash system.
Example: An Australian learner can study Bitcoin's payment record without first buying BTC. Bitcoin names the network and its native asset; the learning exercise is separate from a price prediction.
A batch of Bitcoin transactions plus a header that summarises them and links the block to the one before it.
Example: A clerk groups today's receipts into a numbered packet and refers to the earlier packet. This illustrates batching and linking; Bitcoin also checks the transactions and proof of work.
Keep in mind: This definition describes a Bitcoin block. Other blockchains can use different block contents and consensus rules.
What a miner may claim for a valid block: the block subsidy (newly created bitcoin) plus all transaction fees paid by the transactions in that block.
Example: Imagine a delivery worker receiving a scheduled base payment plus the delivery fees collected. Bitcoin's subsidy and transaction fees are separate parts of its block reward.
Keep in mind: The subsidy creates new units; fees transfer existing units. Neither is a guaranteed return for a person buying BTC.
A shared record organised into linked blocks and maintained under a network's rules for checking and agreeing updates. Participants hold or verify the record in ways that depend on the network design.
Example: Several members of a savings club keep matching copies of an agreed record. A blockchain adds rules for checking and ordering updates rather than trusting a single notebook keeper.
A system that lets tokens or messages move between two blockchains, usually by locking or burning assets on one side and minting or releasing them on the other.
Example: A travel desk accepts one voucher and issues a corresponding voucher for another system. If the desk fails, the second voucher may not be redeemable. Blockchain bridges introduce their own trust dependencies.
A service that arranges or executes crypto purchases or sales for customers. Some quote their own dealing prices; others route orders. Check who acts as the counterparty and how spreads and fees are charged.
Example: A currency kiosk quotes a single all in exchange price instead of showing every customer's offer. A crypto broker may work similarly, so compare its quote and disclosed fees.
Keep in mind: Check the actual contract, counterparty and costs. Services can combine broker and exchange functions.
