Nodes compete to solve computationally intensive cryptographic puzzles (SHA-256, Scrypt, Ethash). The winner broadcasts the valid block and receives newly minted coins as a block reward. Difficulty adjusts dynamically to maintain target block intervals.
Validators lock (stake) existing tokens as collateral to gain the right to propose and attest to new blocks. New coins are issued as staking rewards proportional to stake size. Slashing penalizes dishonest validators by destroying staked tokens.
Supply is minted entirely at genesis (pre-mine) or released on a programmatic schedule via smart contracts — no energy-intensive consensus required. Tokens are distributed via ICO, TGE, airdrops, liquidity incentives, or governance treasury allocations.
New tokens are minted 1:1 against deposited collateral (fiat, crypto, or government backing). Issuers maintain reserves and can mint/burn tokens to maintain peg. CBDCs are centrally issued by sovereign banks with full monetary policy control.
The original cryptocurrency model. Native blockchain currencies secured by computational work. The blockchain IS the ledger; miners compete to extend it and earn block rewards.
Programmable blockchains that host decentralized applications. Native tokens serve as gas fuel, staking collateral, and governance rights. Validators earn staking yields rather than mining rewards.
Cryptocurrencies engineered to maintain a stable price peg, typically to USD. Three distinct architectures: fiat-backed, crypto-backed, and algorithmic. The stability mechanism defines risk profile and decentralization.
Tokens that govern decentralized financial protocols — DEXs, lending markets, yield optimizers. Created via token generation events (TGE), liquidity mining, or DAO treasury allocations. Confer voting rights over protocol parameters.
Cryptocurrencies driven by internet culture, social momentum, and community identity rather than fundamental utility. Often launched with no pre-mine and unlimited or enormous supply. Value is purely speculative and community-driven.
Sovereign digital currencies issued directly by central banks. Legal tender in digital form — neither decentralized nor permissionless. Programmed with monetary policy rules, KYC/AML enforcement, and potential expiry/spending restrictions.
Tokens with specific in-protocol utility: paying transaction fees, accessing services, incentivizing node operators, or representing computational resources. Often pre-mined at launch and released via vesting schedules or ecosystem incentives.
Non-fungible tokens represent unique digital ownership — art, collectibles, virtual land, game items, and intellectual property rights. Gaming tokens (fungible) serve as in-game currency within play-to-earn ecosystems, minted as player rewards.
