Software designed to harm you or your device, for example by stealing data, watching what you type or changing what you copy, paste or see.
Example: A fake update installs a program that watches passwords or changes payment details. Obtain software through verified channels and inspect requests before approving them.
The latest price of one token multiplied by its circulating supply: a snapshot estimate, not money invested or money that could be withdrawn.
Example: An invented price of USD 3 times two million circulating units gives USD 6 million. It does not show that USD 6 million was deposited or can be withdrawn at that price.
An informal belief that one crypto network or asset should dominate, or has meaningful long-term value while alternatives do not. Bitcoin maximalism is one example; people who use the label can hold different views.
Example: A phone fan insists one brand should replace all others. A similar attachment to one crypto network can discourage fair comparison of evidence and tradeoffs.
The stated upper supply limit under an asset's current rules, where such a limit exists. Check how the limit is enforced and whether anyone has power to change those rules.
Example: A ticket printer has a stated lifetime printing limit. Check whether the token's rules actually enforce a cap and who could change those rules.
Keep in mind: A stated maximum is different from currently circulating units or total units already created.
A crypto-asset whose appeal comes mainly from a joke, theme or online community rather than from a product or service.
Example: A themed souvenir becomes popular because an online community enjoys the joke. Popularity can change quickly and does not itself establish cash flows or useful rights.
An extra field, sent with a transfer on certain networks, that tells a receiving service which customer the funds belong to when many customers share one address.
Example: A shared apartment building has one street address but separate flat numbers. A receiving service may need a tag or memo to credit the correct customer.
A node's list of valid transactions that have been broadcast but not yet included in a block.
Example: Different shops have different queues of pending requests. Nodes likewise can have different pending transaction sets; there is not necessarily one identical global mempool.
Creating valid Bitcoin blocks, which requires showing proof of work. A miner is a person who runs mining machines, or the machine itself.
Example: A Bitcoin miner searches for a qualifying header hash, while nodes still check all the block rules. Finding a hash does not make an otherwise invalid transaction acceptable.
A wallet that needs signatures from a set number of separate keys (for example, two of three) before a transaction is valid.
Example: A savings club requires two approvals out of three authorised signers. A two of three wallet similarly needs the required distinct keys; two copies of one key do not provide two signers.
