What is CIP-21 in Cardano?

The Cardano Improvement Proposal (CIP) process is a community-driven mechanism for proposing, discussing, and implementing improvements, upgrades, and changes to the Cardano protocol and ecosystem.

Cardano's role in climate action encompasses its commitment to reducing carbon emissions, promoting renewable energy, and driving sustainable.

Cardano ensures compatibility with legacy systems through interoperability standards and middleware that facilitate seamless integration with traditional IT infrastructure.

Cardano enables fast, secure, cost-effective cross-border payments by leveraging blockchain, bypassing traditional banks, and reducing fees.

Cardano employs a proof-of-stake (PoS) consensus mechanism called Ouroboros, ensuring network security and consensus by selecting participants, known as stakeholders, to validate transactions and produce new blocks based on the amount of ADA they hold and are willing to "stake" as collateral.
