Was Ist Cardano Get started today VideoCardano Staking: Wie stake ich ADA richtig?
Cardano was founded by Jeremy Wood and Charles Hoskinson. It launched in September , which makes it one of the newest cryptocurrencies on the market.
Nevertheless, it managed to climb the rankings by offering a novel approach to the technology. But more on that later.
Charles Hoskinson is an entrepreneur who also took part in founding Ethereum, another innovative platform that launched two years prior to Cardano.
The main differentiating factor of Cardano from the beginning was going to be the academic approach to the technology. This is evident in the naming as well.
Cardano itself takes its name from Girolamo Cardano, an Italian polymath who is credited with the first systematic computations of probabilities.
Furthermore, ADA, which is the native cryptocurrency of the platform is named after Ada Lovelace who was the daughter of Lord Byron, a mathematician who is considered to be the first computer programmer.
There are three organizations that oversee the development of Cardano platform. The Cardano Foundation, which is an independent standards body based in Switzerland, acts as the supervisor and educational body of the platform.
The mission of this organization is to promote and standardize the Cardano Protocol. It is a cryptocurrency research and development company that has been contracted to oversee the development of Cardano platform until The third organization that supports Cardano is called Emurgo.
Emurgo is a venture capital company that helps the platform by integrating and implementing applications on Cardano blockchain. The organization finds and funds such projects to promote the adoption of Cardano blockchain.
The meaning of ADA is simple, it is a cryptocurrency that is based on the Cardano platform. The cryptocurrency provides users with money transfer functionality.
This is the most basic functionality offered by the blockchain networks and the one that was introduced the first. Many believe that digital coins will substitute fiat money to become the most widely used form of currency in the future.
What came about from that was Cardano. As mentioned before, Cardano is unique in the sense that it is built on scientific philosophy and peer-reviewed academic research.
The Cardano team wants to adhere to a set of principles and philosophies. They did not set out with a proper roadmap or a white paper.
Total scalability is a three-headed hydra so to speak. One needs to take care of three separate elements:. Many articles have been written on the lack of throughput in Bitcoin and Ethereum.
Bitcoin manages 7 transactions per second and Ethereum manages This is absolutely not acceptable for a financial system.
Cardano hopes to solve this problem with their consensus mechanism, Ouroboros. It is a provably secure proof-of-stake algorithm. Ouroboros was actually peer-reviewed and approved during Crypto Ouroboros, as stated earlier is a proof-of-stake algorithm.
Before we get deeper into the mechanism, we must know what proof of stake is. Bitcoin and Ethereum for now at least follows the proof-of-work protocol.
That, in essence, is what the proof-of-work system is. Solving the puzzle is difficult but checking whether the solution is actually correct or not is easy.
This is the system that Bitcoin and Ethereum till now have been using. However, there are some fundamental flaws in the system. Ouroboros looks at the distribution of the tokens in the ecosystem and from a source of random numbers, it divides the world into epochs.
Each epoch is then divided into slots. The Slot leader act like miners does in a POW protocol in the sense that they are the ones who choose the blocks that get added to the blockchain.
They can, however, add only one block. As you can see, the slot leaders have a very important role to play in the ecosystem.
These stakeholders are called electors and they are the ones who elect the slot leaders for the next epoch during the current epoch. The more stake the stakeholder has in the system, the more chance they get to be elected as slot leaders.
Now, since the slot leaders have a lot of power, special care must be taken to make the election as unbiased as possible.
There must be some amount of randomness involved. This is why a multiparty computation MPC is done to achieve some form of randomness.
Though the results are randomly generated by each elector, they eventually agree on the same final value. The commitment is a message that contains encrypted shares keep this in mind for the recovery phase and a proof of secret.
After that, an elector signs the commitment with their private key and specifies the epoch number and attaches their public key. Doing this solves two purposes:.
After this is done, the elector sends their commitments to other electors. Think of commitments like a locked box that has a secret in it and there is a special value that unlocks the box.
These openings are also put into the block and then becomes part of the blockchain. By this time, an elector has both commitments and openings.
However, some electors may act maliciously and publish their commitment without the opening. Basically, give the locked box without the passphrase.
In order to circumnavigate this, the honest electors can post all the encrypted shares as mentioned in commitment phase and simply reconstruct the secrets.
This way, even if certain electors act in a malicious manner, the system will still work. This is how Ouroboros gets its Byzantine Fault Tolerance.
Eventually, an elector verifies that the commitments and openings match and when that happens, the secrets from the commitments are extracted which forms a seed.
The seed is a randomly generated byte string. We are electing slot leaders for the next epoch. In order to make sure that the election is as unbiased as possible we needed some sort of randomness.
Now it is time to select the Slot Leaders. To ensure unbiased results, the election system is configured for two inputs. The first one is a multiparty computation system.
The second input is the distribution of wealth or stake. Nodes with greater stake or more coins have increased probability of being elected slot leaders.
Ouroboros also differs from other algorithms in the type and form of incentives offered to stakeholders. The Proof of Work algorithm offers rewards in the form of coins and transaction fees to miners.
Economic rewards are also split between three stakeholders: input endorsers, multiparty computation stakeholders, and slot leaders.
Liveness is complementary to Persistence. For example, they assume that nodes in its network are not absent for prolonged periods of time.
Critics say the assumptions made to implement these properties are faulty. For example, they say the properties assume synchronization between ledgers at any given point of time.
There is the danger that input endorsers, who are responsible for approving transactions for slot leaders, may end up approving the same set of transactions from two different slot leaders.
Die Summe aller Stakes ergibt immer 1 und alle Werte bilden eine Wahrscheinlichkeitsverteilung. Dieser wird dann zum Schöpfer eines neuen Blocks.
Cardano ist zudem die erste Kryptowährung die auf dem Haskell-Code basiert. Dieses Protokoll ist ausgerichtet auf den Schutz der Privatsphäre der Nutzer berücksichtigt aber auch die Bedürfnisse der Regulierungsbehörden.
ADA ist die erste Kryptowährung das mit seinem Protokoll die Anforderungen nuanciert und auf effektiv ausbalanciert.
Dabei ist das ganze System so aufgebaut das man es schnell anpassen kann und bei Bedarf lässt sich dieses schnell weiterentwickeln. Es wird auch in Zukunft möglich sein dezentrale Anwendungen auf der Cardano-Blockchain auszuführen.
Somit kann man den vollen Funktionsumfang von ADA nutzen. Zudem wird verstärkt an der langfristigen Skalierbarkeit gearbeitet um so die Fähigkeiten dieser Kryptowährung zu erweitern.
Während Cardano Ethereum in vielerlei Hinsicht ähnlich ist, gibt es mehrere Unterschiede zwischen den beiden Blockchain-Plattformen:. Die gesamte Planung von Cardano ähnelt sehr der von Ethereum.
Aber nicht nur das allein sondern auch der Zahlungsverkehr von Saaten, Notenbanken und internationalen Unternehmen soll das System verarbeiten können.
Um dies zu erreichen muss ich Cardano deutlich von anderen Kryptowährungen abheben.Yoroi zum Beispiel kann als Erweiterung in Chrome und Firefox installiert werden. US-Dollar in mehr als 1.
