Named after George Gordon Byron, 6th Baron Byron or Lord Byron as he was known, was an English Romantic poet. The Byron era is the first era of the Cardano blockchain, and the kickstart of the entire Cardano blockchain.
The actual start of Cardano can be tracked back to 2015, as the founders of Cardano identified three blockchain-specific challenges to solve: scalability to onboard more users and improve blockchain throughput, interoperability to integrate functionalities and features with other systems, and sustainability for Cardano to last for generations.
In order to solve these challenges, a new open-source, decentralized blockchain network needed to be designed and developed.
With that objective, the Byron era officially began in September 2017 with the launch of the federated era of Cardano. In this era, the founding entities of Cardano would establish the basic infrastructure for Cardano including launching the Ouroboros proof-of-stake consensus protocol to enable transactions, developing user wallets, facilitating exchange listings for its native cryptocurrency ADA, and building the worldwide Cardano community.
