ADA · Smart-contract network
The latest available Cardano reference is $0.18829 on ADA/USD at Coinbase Exchange. It is a read-only market observation, not an executable quote.
A proof-of-stake blockchain for applications and digital assets.
Cardano launched in 2017 after research into its Ouroboros proof-of-stake family of protocols.
Cardano appears in this directory for research, not as an endorsement. Its smart-contract network design should be judged through the documented network, supply, control, and failure model rather than through the ADA unit price alone.
The displayed ADA reference is the latest available observation from Coinbase Exchange for ADA/USD. It belongs to that venue, quote asset, and timestamp; Cardano has no single official global price.
An executable ADA order can differ after spread, depth, slippage, fees, payment method, and location. The market label above shows which currency or asset defines the observed price.
Check validator distribution and finality first, then separate base-layer behaviour from application, bridge, oracle, and contract risk.
Cardano uses a programmable base-layer network where validators order transactions and applications execute shared state.
For ADA, staking rewards draw from reserves and fees within a supply capped by the protocol.
Rule changes depend on the client teams, validators, token holders, foundations, and application ecosystem involved in that network.
The documented ADA role includes paying network fees, staking where supported, and interacting with applications.
For Cardano, material risks include validator concentration, client bugs, smart-contract failures, bridge risk, governance changes, and volatile demand for block space.
Confirm the current ADA software or contract, the supply mechanism, parties with upgrade or administrator authority, dependencies such as validators, issuers or bridges, and liquidity in the exact ADA/USD market. Leave any unsupported field unanswered instead of filling it with a market-cap ranking or social claim.

Stake pools produce blocks under Ouroboros, while protocol development and governance have evolved through staged upgrades.
Cardano emphasizes formal methods and on-chain governance, which should be evaluated through actual participation and control distribution.
