Cardano is a decentralized third-generation proof-of-stake (PoS) blockchain platform whose native token is ADA. Is the first blockchain platform to evolve with science and research as the first driven approach.

To provide an inclusive, equitable and resilient infrastructure for financial and social applications on a global scale. One of its main objectives is to provide reliable and secure financial services to those who do not currently have access to them.

The first generation of blockchain and the second generation of blockchain platform, the transaction speed and scalability is poor, the market is in urgent need of a secure and better scalability solution.

To provide the best solution for speed and scaling issues on other blockchains, the Cardano blockchain is divided into two main layers: settlement layer: This layer works like a ledger containing all historical transactions verified by the Cardano PoS protocol. Computing layer: The DApp layer that runs on Cardano and enforces smart contracts.

Layered design, Ouroboros consensus mechanism.

Pledge mining and pay transaction costs.

Ouroboros' percolation-free consensus mechanism for cryptocurrencies based on proof of stake (PoS).

The third generation of public blockchain contract development platform, excellent scalability, security.

1. Layered technology Cardano's multi-layer protocol performs advanced functions and has a settlement layer on top of it, which is perfectly linked to the control layer. The control layer runs smart contracts and only manages identity, while the settlement layer will have an account unit to perform anonymous transfers by users. The agreement will seek a philosophical balance between regulation and decentralization that balances these requirements in subtle but effective ways, pioneering a cryptocurrency approach. 2. The advanced consensus mechanism ADA is developed based on Ouroboros, a proof of interest algorithm. Ouroboros security system can ensure the mathematical accuracy of Cardano functions. Unlike bitcoin's proof-of-work (PoW) consensus form, Cardano uses proof-of-stake (PoS) to reach consensus. Cardano uses the eUTXO model to insert state into every UTXO on the Cardano blockchain. This is not the global state where Ethereum congestion occurs, so it reduces significant bloat (cost) from the user's perspective when interacting on Cardano. The trade-off is that when interacting with a Plutus smart contract, the agent must "consume" the contract, and consumption of the contract creates problems because other agents cannot interact with the contract at the time. This has to do with Cardano's certainty that when you interact with its smart contract, you know exactly what you're going to get at the output. Each block can perform hundreds of transactions, but in order for multiple agents to interact with the same contract.

ADA issued a total of 45 billion yuan, including 25 billion yuan for platform subscription, 5 billion yuan for development company operation support funds, and 15 billion yuan in the form of block awards.

Took lessons from the bitcoin and Ethereum concepts and improved on their shortcomings. Leverage new discoveries such as layered architectures to improve scalability, security, and sustainability. In this way, they create more utility, fix defects, and correct inefficiencies.

Unlike the competition, Cardano relies heavily on academia. The design of the platform was built from the ground up using an evidence-based approach based on the philosophy of science, academic theory and peer-reviewed research, which ensured the technical safety of Cardano to a certain extent.

Although the Cardano network has completed the smart contract upgrade, a variety of ecological applications are ready to be launched, which seems to be "in full bloom", but there is no application that can carry the banner of Cardano. Whether Cardano network itself can withstand the simultaneous influx of a large number of users remains to be tested.

The current market pattern of public chain has been completely changed. ETH, BSC and Polygon have emerged before, and Solana, Terra, Fantom and other new blockchains have emerged later. The public has seen their performance in the market. Need to start effective strategic layout out of their own independent market.

Bakyt Azimkanov, Cardano MARKETING Director: "Let's be clear. There will be bumps in the road. Early user experiences may not be perfect. Some of the early dapps had problems. We'll see some good teams and some bad teams. This is a permissionless decentralized blockchain, so it's inevitable. Some dapps may not be secure. Cardano's Security Layer 1 platform offers robustness and high assurance, while Plutus aims to minimize the possibility of exploit. But poor coding practices always put DApp users at risk. It is also inevitable that we can expect bad actors to want to exploit through hacking, exploitation of vulnerabilities and so on."

The ecological construction is still in the early stage, and the network scalability needs to be tested. The biggest question ADA has faced since its release is the criticism on the total amount of its issued tokens. With 45 billion coins in circulation and 57.61% of the total, ADA was once questioned about the transparency and liquidity of the currency.

The public track is becoming more and more crowded, and the success of the project largely depends on the construction of the ecology. From this point of view, it faces great competition with other smart contract platforms.
