Cardano: A Peer-Reviewed, Scalable, and Sustainable Proof-of-Stake Blockchain Platform

What is Cardano

Friends, imagine we are building a digital city, and Cardano (ADA) is like the foundation and framework of this city—a very special “blockchain” platform. You can think of blockchain as a public, transparent, and tamper-proof digital ledger, where all transactions and information are recorded and maintained collectively by many people in the network, rather than being controlled by a single central authority.

Cardano aims to be a platform capable of supporting various “decentralized applications” (DApps). DApps (Decentralized Applications) are applications that do not rely on a single server but run on the blockchain, such as decentralized finance (DeFi) services, games, or identity verification systems.

It’s like a highly secure and sustainable digital operating system that not only processes digital currency transactions but also runs complex smart contracts. You can think of a smart contract as a self-executing digital contract: once preset conditions are met, the contract executes automatically, without third-party intervention.

What makes Cardano special is its strong emphasis on scientific research and peer review from the very beginning. This means every major design and technical update is scrutinized and validated by experts, just like scientific papers, striving for the utmost rigor and reliability.

Project Vision and Value Proposition

Cardano’s vision is to build a more secure, scalable, and sustainable blockchain platform to address some of the challenges faced by early blockchain projects (such as Bitcoin and Ethereum), like slow speed, high energy consumption, and limited scalability.

It hopes to provide reliable financial services globally, especially to those currently unable to access traditional banking, achieving “financial inclusion.” Imagine if everyone could securely and conveniently transact, borrow, or even manage their digital identity via their phone—what a huge change that would be!

Compared to similar projects, Cardano emphasizes its “research-first” and “evidence-based development” approach. Instead of developing first and patching later, it conducts in-depth academic research, validates its theoretical foundations through peer-reviewed papers, and then proceeds with engineering implementation. This rigorous development model aims to ensure the system’s security and stability, and better adapt to future development and regulatory needs.

Technical Features

Consensus Mechanism: Ouroboros

Cardano uses a consensus mechanism called Ouroboros, which is a “Proof-of-Stake” (PoS) protocol. You can think of Proof-of-Stake (PoS) as a system where participants in the network “stake” their tokens (ADA) to earn the right to validate transactions and create new blocks, rather than “mining” by consuming large amounts of electricity as in Proof-of-Work (PoW).

Ouroboros is considered the first “provably secure” PoS protocol, meaning it is mathematically proven to be secure and resistant to various attacks. It divides blockchain time into “epochs” and “slots,” with each slot electing a “slot leader” to create new blocks. This mechanism not only greatly reduces energy consumption—making it more environmentally friendly than PoW chains like Bitcoin—but also increases transaction speed and network scalability.

Layered Architecture

Cardano adopts a unique layered architecture, mainly divided into two layers:

• Settlement Layer: This layer mainly handles ADA token transactions, like a bank’s transfer system, ensuring secure and fast movement of funds.
• Computation Layer: This layer focuses on running smart contracts and decentralized applications, like an “operating system” for smart contracts, providing more flexible and powerful functionality.

This separation allows Cardano to be more flexible in upgrades and maintenance, enabling independent improvements to each layer without affecting the entire network’s operation.

Smart Contract Languages: Plutus and Marlowe

Cardano’s smart contract platform is called Goguen, introducing two main smart contract languages:

• Plutus: A smart contract language based on the Haskell programming language, known for its rigor and security, making Plutus smart contracts more reliable.
• Marlowe: A domain-specific language (DSL) designed specifically for financial contracts, allowing non-programmers to easily create and deploy financial smart contracts through a visual interface, lowering the development barrier.

Scaling Solution: Hydra

To further improve transaction processing capacity, Cardano is developing a second-layer (Layer 2) scaling solution called Hydra. You can think of Hydra as opening many “small channels” outside the main chain, each capable of independently processing a large number of transactions, with final results aggregated back to the main chain. In theory, each “head” of Hydra can process up to 1,000 transactions per second, and with multiple heads running simultaneously, the entire system could handle up to 1,000,000 transactions per second, greatly increasing Cardano’s throughput and speed.

Tokenomics

Cardano’s native cryptocurrency is ADA, named after Ada Lovelace, the world’s first computer programmer.

• Token Symbol: ADA
• Issuing Chain: Cardano blockchain
• Maximum Supply: ADA’s total supply is hard-capped at 45 billion, giving it scarcity and preventing inflation from unlimited issuance.
• Current and Future Circulation: As of November 2023, about 36.365 billion ADA are in circulation, with the remaining ADA gradually entering the market through staking rewards and other means.
• Inflation/Burn: ADA’s monetary policy is transparent. In each epoch (about every five days), a portion of the unissued ADA reserve flows into the reward pool, part of which is used to reward stakers, and another part goes to the treasury for project development.
• Token Utility:
  • Transaction Fees: Any transaction on the Cardano network requires ADA as a fee.
  • Staking: ADA holders can stake their tokens to a “stake pool” to participate in network security and earn ADA rewards.
  • Governance: ADA holders have voting rights and can participate in Cardano network governance, voting on important proposals such as protocol upgrades and fund allocation, jointly deciding the project’s future direction.
  • Smart Contract and DApp Interaction: ADA is the default currency for interacting with smart contracts and decentralized applications on Cardano.
• Token Distribution: The initial ADA distribution included: 57.6% distributed via public sale (ICO), 30.9% for network incentives and ecosystem growth, 5.5% allocated to IOHK, 4.6% to EMURGO, and 1.4% to the Cardano Foundation.

Team, Governance, and Funding

Core Team and Partner Organizations

The Cardano project is developed and maintained by three independent entities, each with its own responsibilities, jointly driving the development of the Cardano ecosystem:

• Input Output Global (IOG, formerly IOHK): A blockchain engineering and research company founded in 2015 by Ethereum co-founder Charles Hoskinson and Jeremy Wood. IOG is responsible for Cardano’s core technology development and research, adhering to rigorous academic methods and evidence-based development.
• Cardano Foundation: An independent non-profit organization based in Switzerland. Its role is to oversee Cardano’s development, promote its ecosystem, and work with regulators to advance blockchain legislation and business standards.
• EMURGO: Cardano’s official commercial arm, responsible for driving Cardano’s commercial adoption and ecosystem growth through investment, project incubation, and providing solutions.

Governance Mechanism

Cardano’s governance model aims for true decentralization, allowing ADA holders to participate in platform decision-making. With the advent of the Voltaire era, Cardano is transitioning to a system fully maintained and governed by the community.

Core governance mechanisms include:

• CIP-1694: An important improvement proposal introducing a tricameral governance structure, aiming to give every ADA holder a voice in governance.
• Delegated Representatives (DReps): ADA holders can delegate their voting rights to DReps, who vote on their behalf.
• Stake Pool Operators (SPOs): These are node operators who maintain the network and produce blocks, and also participate in voting on certain governance actions.
• Constitutional Committee (CC): A committee composed of elected representatives responsible for ensuring governance actions comply with Cardano’s constitution.

Any ADA holder can submit governance proposals, which require approval from at least two governance roles (DReps, SPOs, and CC) to be executed. In addition, Cardano has a treasury system to fund community-proposed projects and development.

Roadmap

Cardano’s development roadmap is divided into five main “eras,” each focusing on delivering a specific set of features, with work proceeding in parallel.

• Byron Era: Cardano’s founding phase, establishing the basic blockchain network, allowing users to buy and sell ADA, and launching wallets such as Daedalus and Yoroi.
• Shelley Era: This phase achieved network decentralization, transferring block production and transaction validation power from founding entities to a distributed community of stake pool operators, and introduced staking rewards.
• Goguen Era: This phase introduced smart contract functionality, enabling developers to build decentralized applications (DApps) on Cardano, including smart contract languages like Plutus and Marlowe.
• Basho Era: This phase focuses on network scalability, aiming to improve Cardano’s performance and throughput, for example through second-layer solutions like Hydra.
• Voltaire Era: The final stage of Cardano’s roadmap, aiming for full decentralized governance, introducing voting and treasury systems to allow the community to autonomously decide the network’s future development and fund usage.

Currently, Cardano is in the development of the Basho and Voltaire eras, with plans to complete the roadmap within the next two and a half years.

Common Risk Warnings

Investing in any cryptocurrency comes with risks, and Cardano is no exception. Here are some common risks to be aware of:

• Market Volatility Risk: The cryptocurrency market is extremely volatile, and ADA’s price may rise or fall sharply in a short period. Even with staking rewards, market price fluctuations cannot be completely eliminated.
• Technical and Security Risks: Although Cardano is known for its rigorous development approach, smart contracts may still have vulnerabilities that malicious actors could exploit. In addition, network attacks (such as double-spending attacks) and software bugs may affect network security.
• Competition Risk: Cardano operates in a highly competitive smart contract blockchain sector, facing competition from projects like Ethereum, Solana, Avalanche, and more. If Cardano is slow in user adoption and application development, it may affect its long-term sustainability.
• Governance Risk: Although decentralized governance is Cardano’s goal, internal community disagreements or malicious behavior could still lead to governance disputes or protocol instability.
• Compliance and Operational Risk: The global cryptocurrency regulatory environment is constantly evolving, and uncertain regulatory policies may pose legal risks to the Cardano ecosystem.
• Fraud Risk: The crypto space is rife with scams, such as fake giveaways, phishing, and fraudulent investment opportunities. Be wary of any promise asking you to send ADA for “double returns” or requesting your seed phrase (recovery phrase).

Remember: Any investment claiming “guaranteed high returns” is a red flag. Never share your seed phrase or private key.
