À propos de Cardano
Cardano is an open-source, smart-contract-enabled Layer-1 blockchain protocol. It uses a Proof-of-Stake consensus mechanism known as Ouroboros. Cardano is designed for various use cases, including finance, identity management, and supply chain tracking.
Contexte
Cardano was founded in 2015 by Charles Hoskinson (former Co-Founder of Ethereum) and Jeremy Wood (former Executive Assistant at Ethereum). Charles is said to have disagreed with Vitalik Buterin's direction for Ethereum, wishing to create a privately-backed company to oversee network development. Thus, Charles and Jeremy left Ethereum and started a blockchain research and development company called Input Output Hong Kong (IOHK), now rebranded to Input Output Global (IOG). They had the vision of addressing the three challenges facing all blockchains: scalability, interoperability, and sustainability.
Cardano’s development is methodical and deliberate, prioritizing sustainability and stability over speed. Cardano’s roadmap consists of five eras that occur sequentially, though often in parallel, with most eras continuing to be iterated on:
Byron (Foundation)
Shelley (Decentralization)
Goguen (Smart Contracts)
Basho (Scaling)
Voltaire (Governance)
