Cardano
Welcome to Cardano!
Cardano is a public blockchain platform. It is open-source and decentralized, with consensus achieved using proof of stake. It can facilitate peer-to-peer transactions with its internal cryptocurrency, ADA.
Cardano's development began in 2015, led by Ethereum co-founder Charles Hoskinson. The project is overseen and supervised by the Cardano Foundation based in Zug, Switzerland. When launched in 2017, it was the largest cryptocurrency to use a proof-of-stake blockchain, which is seen as a greener alternative to proof-of-work protocols. On this community you can learn more about the project, understand its great potential and engage in the worldwide Cardano community!
**Governance: ** Cardano is controlled by three entities:
Cardano Foundation: aims to standardize and promote the ecosystem (based in Switzerland). As of 2021, Frederik Gregaard is known to be the CEO of the Cardano Foundation.
IOHK: an engineering company responsible for building the Cardano blockchain.
Emurgo: responsible for commercial applications, based in Japan.
The platform is named after Italian mathematician Gerolamo Cardano, while the cryptocurrency itself is named after the English mathematician Ada Lovelace. The Ada sub-unit is the Lovelace; one Ada = 1,000,000 Lovelaces. Cardano differentiates itself from many other cryptocurrencies by focusing on scientific research and working together with universities.
Technical design:
Atypically, Cardano does not have a white paper. Instead, it uses design principles intended to overcome issues faced by earlier cryptocurrencies such as scalability, interoperability, and regulatory compliance. Cardano claims that it overcomes problems found in other cryptocurrencies: mainly that Bitcoin is too slow and inflexible, and that Ethereum is not safe or scalable. Like Bitcoin, Cardano uses a UTXO ledger model, though it is an extended version (EUTXO) to facilitate smart contracts and scripting languages.
Cardano uses a proof-of-stake (PoS) protocol named Ouroboros; this is in contrast to Bitcoin and Ethereum, which use proof-of-work protocols (though the latter switched over in 2022). Proof-of-stake blockchains use far less energy than proof-of-work chains. This is achieved by eliminating the computing resources that a proof of work algorithm requires. In February 2021, Hoskinson estimated the Cardano network used 6 GWh annually, less than 0.01% of the 110.53 TWh used by the Bitcoin network as calculated by the University of Cambridge.
Within the Cardano platform, Ada exists on the settlement layer. This layer is similar to Bitcoin and keeps track of transactions. The second layer is the computation layer and is designed to be similar to Ethereum, enabling smart contracts and applications to run on the platform.
The cryptocurrency Ada (ADA) can be stored on Cardano's native digital wallet named "Daedalus". The wallet downloads a full copy of the entire Cardano blockchain transaction history. Users face the risk of losing access to funds if the wallet's seed phrase is lost or stolen. The review in Investopedia highlighted the wallet's security and noted the lack of: mobile support, support for other tokens, and "onramp" to purchase assets with money.
Development phases of Cardano, or "eras", are named after notable figures in poetry and computer science: Byron, Shelley, Goguen, Basho and Voltaire. The first three stages implemented a basic blockchain, and then implemented decentralization and smart contracts. The Basho era focuses on scaling the blockchain. Voltaire, the final era, adds voting and treasury management functionality to the blockchain.
Once Voltaire is complete IOHK has said it plans to release the development of the network entirely to the community.
As with other proof-of-stake cryptocurrencies, Cardano offers "staking", which allows token holders to set-aside (delegate) tokens to potentially "validate" transactions on the same blockchain. The quantity of tokens staked corresponds with the likelihood of being chosen to validate a transaction, and thus be rewarded by the algorithm with more of the same token. Cardano's Daedalus wallet allows for staking. For Cardano, users participate in "staking pools" with other token-holders.

When you say ‘crypto’, do you mean cryptocurrency or an application of blockchain in a non-currency role?
I’m genuinely intrigued by the idea because I hate hate hate unnecessary middlepersons. I am sincerely interested how crypto/blockchain would help achieve this worthy goal.
If you can feasibly think of a way to effectively decentralize computation in order to create incentives for server owners to run a public network without involving crypto, I am all ears. If not, of course I am talking about cryptocurrency.
I have committed a lot of thought on this topic and, IMO, crypto is currently the only way to run a decentralized, open source platform where the nodes have an incentive to behave honestly.
Lemmy is a great case in point. On a long enough timeline, instance operators will need to secure funding or they will need to shut down. If they had some kind of openly-auditable incentive mechanism with rewards for longevity and reliability, it would be the best possible way to keep the system self-sustaining, uncorrupted by external financial influence, censorship-free, and reliable. *Even if Lemmy were considered a public good, funded by governments, even that would introduce a tendency toward censorship which might not exist if you compared it with a crypto-based system. *
ps. if you think I am crazy for thinking about this stuff in regards to lemmy/kbin right now, have a look at kbin's source code.
pps. I am psyched to have these kinds of discussions. Thanks for the engagement and keep it going. It's fascinating to me.
To play devil's advocate, the biggest issues I can currently find with this idea:
Thanks for clarifying! The devil is certainly in the details. Worth hashing out.
Thanks for pointing out how cryptocurrency might be used to incentivize running a server to enable “p2p” ride sharing. I mean it’s not exactly p2p if there’s a server in the middle, but that’s how it would appear to riders and drivers ideally.
As a non sequitur, everyone always forgets about craigslist. They are still around and are quite active, not the same as in the early days but craigslist is still a viable concern.
There’s nothing fancy or exotic about their tech, the innovation and disruption came from the business model alone. Just throwing that out there as an appeal for simplicity and a discussion point. Maybe follow a craigslist model and charge a small fee for commercial load-sharing and the personal ride-shares can free-ride on the same infrastructure?
I have a bias toward simplifying big ideas as much as possible. The main challenge with a cryptocurrency based approach is you have to have mass adoption of two big new ideas at the same time: crypto and decentralized ride-sharing.
Again, great discussion point. I want this idea to take root so I am just being a devil’s advocate. I realize this is a cardano forum, so naturally the audience will like the application of cryptocurrency.
no problem! I will edit this comment more later but I have a big smile on my face because you come from the same spirit of intellectual honesty and idealistic curiosity that I do.
In the vast possibilities of technological evolution, should an innovation emerge that propels us closer to a truly egalitarian civilization, whether it be cryptocurrency or of some other nature, it is the outcome, not the medium, that truly resonates with me.
Ha! Looking forward to it. It would be interesting to cross post or repost this in different communities to get different audiences.
I could see Minneapolis saying ‘byeeee’ to Uber and making a public service. That isn’t much different from governments giving out taxi medallions, save that they hopefully wouldn’t limit the supply to create artificial scarcity.
Anyhow, good times!
