Platformo so začeli razvijati v letu 2015 in jo je javnosti leta 2017 predstavil [[Charles Hoskinson]], ki je soustanovitelj platform [[Ethereum]] in [[BitShares]].<ref>{{Navedi splet|title=Ethereum Cofounder Says Blockchain Presents 'Governance Crisis'|url=https://fortune.com/2019/04/08/ethereum-cofounder-governance-charles-hoskinson/|accessdate=1. aprila 2020|website=Fortune|language=en}}</ref> <ref name="EthereumCo-founder">{{Navedi splet|date=6. oktober 2017|title=ICOs explained|url=https://www.cnbc.com/2017/10/05/how-icos-setting-the-vc-world-ablaze-work.html|accessdate=25. decembra 2018|website=[[CNBC]]|quote="ethereum co-founder Charles Hoskinson says it has become increasingly more challenging to regulate this new asset class" and "ICO market could crash"}}</ref> <ref name="Forbes_Story">{{Navedi novice|last=Au-Yeung|first=Angel|date=7. februar 2018|title=A Fight Over Ethereum Led A Cofounder To Even Greater Crypto Wealth|url=https://www.forbes.com/sites/angelauyeung/2018/02/07/charles-hoskinson-ethereum-iohk-blockchain-crypto-cryptocurrency/|accessdate=12. julija 2020|work=Forbes Magazine|quote=IOHK's key project: Cardano, a public blockchain and smart-contract platform which hosts the Ada cryptocurrency.}}</ref> Hoskinson pravi, da je Ethereum zapustil po sporu glede ohranjanja neprofitnosti platforme Ethereum. Po odhodu je skupaj s fundacijo Cardano in družbo Emurgo soustanovil podjetje IOHK za inženiring veriženja blokov, ki v sodelovanjus fundacijo Cardano in družbo Emurgo razvija platformo Cardano. Platforma je poimenovana po [[Gerolamo Cardano|Gerolamu Cardanu]], kriptovaluta pa po [[Ada Lovelace|Adi Lovelace]].<ref name="ada lovelace">{{Navedi splet|title=What is Ada?|url=https://cardano.org/what-is-ada/|accessdate=23. oktobra 2020}}</ref>
 
Valuta je prvič nastopila s tržno kapitalizacijo 600 milijonov dolarjev. Do konca leta 2017 je dosegla tržno kapitalizacijo 10 milijard dolarjev in leta 2018 na kratko vrednost 33 milijard dolarjev, preden se je vrednost zaradi splošnega zaostrovanja trga kriptovalut znižala na 10 milijard dolarjev. Po poročanju medijske hiše Mashable Cardano trdi, da premaguje obstoječe težave na kriptovalutnem trgu; predvsem to, da je [[bitcoin]] prepočasen in neprilagodljiv ter da [[ether]] ni varen ali razširljiv. Avtorji Cardano štejejo za kriptovaluto tretje generacije.<ref name="CardanoGeneral">{{Navedi splet|date=24. februar 2018|title=Cardano: a rising cryptocurrency|url=https://mashable.com/2018/02/24/cardano-hoskinson-interview/?europe=true#M7WXfcgYIkq2|accessdate=25. decembra 2018|website=[[Mashable]]|quote=Cardano claims it will solve most of the issues that plague well-established cryptocurrencies such as Bitcoin and Ethereum}}<cite class="citation web cs1" data-ve-ignore="true">[https://mashable.com/2018/02/24/cardano-hoskinson-interview/?europe=true#M7WXfcgYIkq2 "Cardano: a rising cryptocurrency"].

Cardano uporablja tehnologijo [[Dokaz o vložku|dokaza o vložku]] [[Ouroboros (protokol)|Ouroboros]]. Bitcoin pa nasprotno uporablja sistem dokaza o delu; za določanje poštene verige blokov se uporabljata prvi vnos v verigo blokov in najdaljša veriga blokov (veriga blokov z največ računalniške moči). Cardano uporablja samo prvi vnos v verigo blokov, nato pa se poštena veriga dokazuje lokalno, ne da bi bila za to potrebna zaupanja vredna stranka.<ref>{{Navedi časopis|last=Badertscher|first=Christian|last2=Gaži|first2=Peter|last3=Kiayias|first3=Aggelos|last4=Russell|first4=Alexander|last5=Zikas|first5=Vassilis|date=2018-01-15|title=Ouroboros Genesis: Composable Proof-of-Stake Blockchains with Dynamic Availability|url=https://doi.org/10.1145/3243734.3243848|journal=Proceedings of the 2018 ACM SIGSAC Conference on Computer and Communications Security|series=CCS '18|location=Toronto, Canada|publisher=Association for Computing Machinery|pages=913–930|doi=10.1145/3243734.3243848|isbn=978-1-4503-5693-0}}</ref>
 
Kriptovaluta Ada deluje v platformi Cardano Ada na poravnalni ravni. Ta raven je podobna kot pri [[Bitcoin|bitcoinu]] in beleži transakcije. Druga raven je računska raven. Ta je podobna [[EthereumEther|etruetherju]] in omogoča izvajanje pametnih pogodb in aplikacij na platformi.<ref name="CardanoGeneral">{{Navedi splet|date=24. februar 2018|title=Cardano: a rising cryptocurrency|url=https://mashable.com/2018/02/24/cardano-hoskinson-interview/?europe=true#M7WXfcgYIkq2|accessdate=25. december 2018|website=[[Mashable]]|quote=Cardano claims it will solve most of the issues that plague well-established cryptocurrencies such as Bitcoin and Ethereum}}<cite class="citation web cs1" data-ve-ignore="true">[https://mashable.com/2018/02/24/cardano-hoskinson-interview/?europe=true#M7WXfcgYIkq2 "Cardano: a rising cryptocurrency"].

Cardano nima [[bel papir|bele knjige]] (predstavitvenega dokumenta).
