Crypto terms, explained plainly
124 short definitions and a handful of guides. Every term links to the coins and charts where you will meet it, and the ones the model actually uses say so.

A

- AltcoinBasics
Any crypto asset other than Bitcoin; a broad label rather than a shared design.
B
- Bitcoin dominanceBasics
Bitcoin's share of the total crypto market cap, used as a rough risk-appetite gauge.
C
- Circulating supplyBasics
The coins that exist and can be traded right now, as opposed to the total ever created.
- Consensus mechanismBasics
The rule that decides which version of a chain's history is correct — proof of work or proof of stake.
D
- DrawdownBasics
The fall from a previous peak to the current low; max drawdown is the worst one on record.

G
- Genesis blockBasics
The first block of a blockchain, the anchor every later block traces back to.
H
- HalvingBasics
The scheduled cut in new Bitcoin issued per block, every 210,000 blocks, roughly four years.

The hard ceiling on how many coins a protocol will ever create, where one exists.
P
- PegBasics
The target price a stablecoin or wrapped asset is meant to hold, usually $1.
- Proof of stakeBasics
Consensus by locking tokens to propose and attest blocks, with slashing for misbehaviour.
