 ==== Decentralization and proof-of-stake consensus
 Cardano achieves full _decentralization_ through over 3,000 community-operated _stake pools_. Over 1.3 million wallets delegate their ada to these pools, representing approximately 64% of the total active ada supply. Network participants validate all blocks and transactions without reliance on a centralized authority, sharing decisions and ownership of information amongst all users. Every ada holder holds a stake in the network, allowing them to delegate their ada to a stake pool to earn rewards and participate in network operations. Stake pool operators can also pledge ada to increase their pool's likelihood of receiving rewards.

Ouroboros has been rigorously proven to provide the same security guarantees as proof-of-work protocols, while being significantly more _energy-efficient_. You can learn more about Ouroboros in the dedicated chapter.

 - _Security_(((security))) — Cardano is developed using _formal methods_, which involve mathematical specifications and proofs to guarantee the functional correctness of its core components, providing the highest level of assurance for digital fund management. The Cardano node is primarily written in _Haskell_, a secure functional programming language that promotes building systems with pure functions, leading to isolated and testable components. Haskell's advanced features enable rigorous code correctness checks, including formal and executable specifications, extensive property-based testing, and simulation. The Ouroboros protocol further establishes rigorous security guarantees, backed by numerous peer-reviewed papers presented at top-tier conferences in cybersecurity and cryptography.
 
-- _Scalability_(((scalibility))) — Cardano is designed to _scale with user demand_, processing an increasing number of transactions and enhancing network bandwidth to manage significant supportive data efficiently. Cardano employs techniques like data compression and offers Hydra, a Layer 2 scalability solution. It also uses input endorsers to improve block propagation times and throughput, supporting higher transaction rates.

 - _Interoperability_(((interoperability))) — this is a fundamental design feature, enabling interaction with other systems. A key innovation is _partner chain support_, facilitating asset transfers between parallel blockchains with different rules, mechanisms, languages, or network utilization methods. Work is ongoing to support cross-chain transfers, multiple token types, and commonly used smart contract languages, with the _partner chains toolkit_ marking the initial step.
