In Bitcoin, the scheduled reduction by half of the new block subsidy every 210,000 blocks under its issuance rules. It changes new issuance, not existing wallet balances or transaction fees.
Example: A production schedule cuts new output after a specified count, rather than on an exact calendar anniversary. Bitcoin's halving is tied to block height and does not halve existing balances.
A fixed-length fingerprint produced from data by a specified cryptographic hash function, within that function’s supported input limits. Identical inputs give the same output. Changed inputs ordinarily give different outputs, although collisions are mathematically possible.
Example: A file checking tool produces a fingerprint for a receipt file. A changed file will normally have a different fingerprint. A hash is not encryption and does not prove that the receipt's contents are true.
A token whose contract lets people buy but blocks or heavily penalises selling, usually through hidden rules that only the creator can bypass.
Example: A shop takes payment but secretly blocks returns under rules the owner can bypass. A token can similarly permit buying while imposing hidden barriers to selling.
A wallet whose private keys are stored on an internet-connected device: convenient for regular use, but more exposed to malware and remote attacks.
Example: Keeping a spending wallet on a phone is convenient, like keeping everyday cash within reach. An online signing environment also increases exposure to malware and deceptive requests.
