Key Cardano Features

1. Proof of Stake (PoS)

Cardano uses Proof of Stake (PoS) to select validators who produce blocks for the blockchain. Two key participants in this process are:

• Validators: Nodes that add blocks to the blockchain.
• Delegators: ADA holders who delegate their right to produce blocks to a validator.

Anyone holding ADA has the right to produce blocks, but not everyone has the necessary hardware or expertise. Delegation allows ADA holders to participate in network consensus without becoming validators themselves.

When multiple delegators pool their stakes with a validator, it forms a stake pool. Block production occurs during slots, which are grouped into epochs, each lasting about 5 days.

2. Ourobos

Ouroboros powers Cardano as the first secure, peer-reviewed proof-of-stake protocol. It combines advanced technology and verified mechanisms to ensure security and sustainability. With Ouroboros, Cardano provides a secure, energy-efficient blockchain for global, permissionless networks.

3. Hard Fork Combinator

Cardano’s hard fork combinator enables seamless blockchain upgrades without disrupting its history or security. Traditional hard forks often create splits and reset the chain, but Cardano’s method combines old and new codebases into one continuous chain.
