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.
Taking an action intended to reduce exposure to a specified risk, sometimes by taking an offsetting position. It can have costs and leave other risks.
Example: An importer worries that a future foreign-currency invoice will cost more in home currency and considers a way to fix its conversion terms.
Keep in mind: A hedge is not a promise of profit or protection from every possible loss.
An accounting arrangement allowing separately identified positions, including opposite directions, subject to the platform and account settings.
Example: A 1,000-unit long and a new 600-unit short may remain two positions rather than one 400-unit long.
Keep in mind: The label does not prove that the combined account has no risk or costs.
A selected high above a previous comparable selected high under the same observation rule.
Example: Invented confirmed highs of 10 then 12 show a higher high.
Keep in mind: One comparison alone does not establish a complete trend or identify a future move.
A selected low above a previous comparable selected low under the same observation rule.
Example: Invented confirmed lows of 7 then 8 show a higher low.
Keep in mind: Keep timeframe and confirmation rules consistent before combining it with higher-high observations.
Seeing a completed event as more obvious or predictable than it was with the information available beforehand.
Example: After a rainy picnic, someone says the weather was obviously going to turn despite their earlier uncertain forecast.
Keep in mind: Preserve the original dated reasoning rather than rewriting it after the outcome.
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.
