Base-layer networks
Bitcoin prioritises monetary predictability and censorship resistance. Ethereum is a programmable settlement layer. Other networks trade among speed, cost, decentralisation, reliability, and developer reach.
A network's token economics, validator set, client diversity, upgrade process, and bridge exposure matter as much as headline throughput.
Exchanges and custodians
Centralised exchanges connect bank money to crypto and provide liquid order books. Their convenience introduces counterparty risk: customers depend on the operator's reserves, controls, and governance. Decentralised exchanges replace the operator with smart contracts but introduce code, liquidity, and transaction-ordering risks.
Stablecoin issuers
Dollar-linked tokens are the market's working capital. Reserve-backed stablecoins depend on custody, banking partners, and redemption. Crypto-collateralised designs depend on robust collateral and liquidation systems. Algorithmic designs can fail when confidence and liquidity disappear together.
Miners and validators
These operators order transactions and secure consensus. Their incentives come from issuance, transaction fees, and—in some systems—extractable value. Concentration in pools or staking providers can create governance and censorship pressure even when thousands of machines participate.
Institutions and regulators
Asset managers, payment companies, banks, venture funds, and public companies connect crypto markets with traditional capital. Regulators define how exchanges, issuers, taxes, disclosures, and consumer protections operate. Rules vary by jurisdiction and change over time.
When evaluating a project, map every party required for custody, data, liquidity, governance, and redemption. A system is only as resilient as its critical dependencies.
