INDEX:80 / Learn / Charles Hoskinson
FROM CARDANO'S BEGINNING TO MIDNIGHT.
Charles Hoskinson is a co-founder of Cardano and founder and CEO of Input Output Group. His story provides a useful route through Cardano's origins, its move from founding-entity stewardship toward community governance, and the newer privacy-focused Midnight network.
Cardano began in 2015. Current Cardano documentation identifies Charles Hoskinson and Jeremy Wood as the people who started the project, with mainnet launching in September 2017.
At genesis, responsibility was divided across three organisations rather than concentrated in one body: Input Output led research and engineering, the Cardano Foundation supported stewardship and ecosystem development, and EMURGO focused on commercial adoption.
The research-first project was formed in 2015 and Cardano mainnet launched in September 2017. In the Byron era the network began in a federated form, with the founding entities responsible for block production and validation.
FOUNDATIONShelley moved Cardano toward decentralized block production, stake pools and community participation rather than relying on the founding entities to operate the network.
DECENTRALIZATIONGoguen brought native assets and programmable smart contracts, including the Mary and Alonzo upgrades, expanding Cardano from a currency ledger into a platform for applications and tokens.
SMART CONTRACTSBasho focuses on scaling and performance. Technologies such as Hydra sit within the wider effort to increase capacity while preserving Cardano's security and settlement model.
SCALINGVoltaire is Cardano's governance era. On-chain governance, DReps, the Constitutional Committee and community decision-making replace the idea that the original organisations should permanently control the chain.
GOVERNANCECardano's current governance documentation records that the pioneer entities — EMURGO, Input Output and the Cardano Foundation — have relinquished the genesis keys as governance has matured and moved to the community.
TODAYInput Output was founded in 2015 and became the principal research and engineering organisation behind Cardano's original protocol work. Its current organisation is broader than Cardano: Input Output now describes itself as a venture studio and systems company spanning research, infrastructure and multiple blockchain ventures.
Charles remains founder and CEO of Input Output. INDEX:80 treats his role as historically important without treating Cardano as a company he controls: the network has deliberately evolved toward decentralized operation and community governance.
Midnight is one of Input Output's major newer ventures. It is a privacy-focused Layer 1 blockchain using zero-knowledge technology for programmable data protection. It has deep Cardano and Input Output roots, but it should not be described simply as a privacy layer for Cardano.
Midnight mainnet's genesis block was created on 17 March 2026. The ecosystem is now supported by the independent Midnight Foundation, while Shielded — a spinout from Input Output — develops privacy-enhancing decentralized technology around the network.
The connection is useful historically: Cardano was conceived as a third-generation blockchain focused on scale, interoperability and governance; Midnight extends Input Output's research into a separate network centred on programmable privacy and data protection.
